A liquid crystal display (LCD) usually has a plurality of pixels (e.g., each pixel includes a red sub-pixel, a green sub-pixel and a blue sub-pixel), and the plurality of pixels may cooperate with one another to enable the LCD to display images.
Each of the above-mentioned pixels further includes a white sub-pixel, so that the white sub-pixel may be used to improve a display brightness of the LCD.
However, since an area occupied by each pixel in the LCD is basically constant, and a ratio of an area occupied by the white sub-pixel to a total area occupied by the red sub-pixel, the green sub-pixel and the blue sub-pixel in each pixel is high, it is easy to make a ratio of brightness of white light displayed by the white sub-pixel to brightness of white light displayed by the red sub-pixel, the green sub-pixel and the blue sub-pixel together high, which exceeds a brightness specification of white light of a product, thereby easily causing the waste of the white light. Moreover, a proportion of the total area occupied by the red sub-pixel, the green sub-pixel and the blue sub-pixel is small, so that a brightness of a single color image, such as red, green, or blue is easily reduced, and in turn, image quality of the single color image is reduced.
Based on this, some embodiments of the present disclosure provide an array substrate 100. As shown in
Colors corresponding to the plurality of primary color sub-pixel regions P1 may include a first color, a second color and a third color. The first color, the second color and the third color include various types, which may be selectively set according to actual needs.
In some embodiments, as shown in
In some other examples, the first color includes magenta, the second color includes yellow, and the third color includes cyan. That is, the plurality of primary color sub-pixel regions P1 may include a plurality of magenta sub-pixel regions, a plurality of yellow sub-pixel regions, and a plurality of cyan sub-pixel regions.
The plurality of sub-pixel regions P are arranged in an array, that is, the plurality of white sub-pixel regions W1 and the plurality of primary color sub-pixel regions P1 are arranged in the array. An arrangement between the plurality of white sub-pixel regions W1 and the plurality of primary color sub-pixel regions P1 includes various types, which may be selectively set according to actual needs.
Herein, the arrangement between the plurality of white sub-pixel regions W1 and the plurality of primary color sub-pixel regions P1 will be schematically illustrated by considering an example where the plurality of primary color sub-pixel regions P1 include the plurality of red sub-pixel regions R1, the plurality of green sub-pixel regions G1 and the plurality of blue sub-pixel regions B1.
In some examples, as shown in
In some other examples, as shown in
In still some other examples, as shown in
It will be noted that, in the row direction X, in the multiple sub-pixel regions P in each row, there is no limitation to the single arrangement in which the red sub-pixel region R1, the green sub-pixel region G1, the blue sub-pixel region B1, and the white sub-pixel region W1 are alternately arranged in sequence, and these sub-pixel regions may be arranged in other orders, for example, two or three of the red sub-pixel region R1, the green sub-pixel region G1, the blue sub-pixel region B1 and the white sub-pixel region W1 are alternately arranged in sequence. Accordingly, the arrangement between the plurality of white sub-pixel regions W1 and the plurality of primary color sub-pixel regions P1 is not limited to the three illustrated above.
In addition, in the column direction Y, dimensions of the plurality of sub-pixel regions P included in the array substrate 100 are equal or substantially equal. In borders of the multiple sub-pixel regions P in each row, connection lines between some of the borders located at a same side in the row direction X are straight lines or substantially straight lines.
In some examples, the row direction X intersects the column direction Y. An included angle between the row direction X and the column direction Y may be selectively set according to actual needs. For example, the row direction X and the column direction Y may be perpendicular to each other.
The “row” mentioned herein does not refer to a row direction on paper; the “column” mentioned herein does not refer to a column direction on paper. In some cases, embodiments involving “row direction” may be implemented in a case of “column direction”, and vice versa. It is also within the scope of the claims to be protected by the present disclosure to rotate or mirror the solution of the present disclosure by 90°.
In some embodiments, as shown in
The first substrate 1 may include various types, which may be selectively set according to actual needs.
For example, the first substrate 1 may be a blank base substrate. For another example, the first substrate 1 may include the blank base substrate and a functional film (e.g., a buffer layer) disposed on a side of the blank base substrate.
The blank base substrate may include various types, which may be selectively set according to actual needs. For example, the blank base substrate may be a polymethyl methacrylate (PMMA) base substrate or a glass base substrate.
In some embodiments, the array substrate 100 further includes a plurality of sub-pixels S disposed on a side of the first substrate 1. In a case where the first substrate 1 includes the blank base substrate and the functional film disposed on the side of the blank base substrate, the plurality of sub-pixels S may be disposed on a side of the functional film away from the blank base substrate.
In some examples, the plurality of sub-pixels S include a plurality of white sub-pixels W2 and a plurality of primary color sub-pixels S1.
Here, colors corresponding to the plurality of primary color sub-pixels S1 are the same as the colors corresponding to the plurality of primary color sub-pixel regions P1. That is, the plurality of primary color sub-pixels S1 may include a plurality of first color pixels S11, a plurality of second color sub-pixels S12 and a plurality of third color sub-pixels S13.
In a case where the plurality of primary color sub-pixel regions P1 include the plurality of red sub-pixel regions R1, the plurality of green sub-pixel regions G1 and the plurality of blue sub-pixel regions B1, the plurality of first color sub-pixels S11 may include a plurality of red sub-pixels R2, the plurality of second color sub-pixels S12 may include a plurality of green sub-pixels G2, and the plurality of third color sub-pixels S13 may include a plurality of blue sub-pixels B2. In a case where the plurality of primary color sub-pixel regions P1 include the plurality of magenta sub-pixel regions, the plurality of yellow sub-pixel regions, and the plurality of cyan sub-pixel regions, the plurality of first color sub-pixels S11 may include a plurality of magenta sub-pixels, the plurality of second color sub-pixels S12 may include a plurality of yellow sub-pixels, and the plurality of third color sub-pixels S13 may include a plurality of cyan sub-pixels.
It will be noted that arrangement positions of the plurality of white sub-pixels W2 correspond to arrangement positions of the plurality of white sub-pixel regions W1, and arrangement positions of the plurality of primary color sub-pixels S1 correspond to arrangement positions of the plurality of primary color sub-pixel regions P1. That is, an arrangement between the plurality of white sub-pixels W2 and the plurality of primary color sub-pixels S1 is the same as the arrangement between the plurality of white sub-pixel regions W1 and the plurality of primary color sub-pixel regions P1.

It will be noted that the area of the above-mentioned opening refers to a difference between an area occupied by a sub-pixel region P and an area occupied by light-shielding patterns 2 located in the sub-pixel region P.
Therefore, in the array substrate 100 provided by some embodiments of the present disclosure, by setting the arrangement of the plurality of sub-pixels S, in the column direction Y, the side of each white sub-pixel W2 is adjacent to the at least one primary color sub-pixel S1, and the part of the plurality of light-shielding patterns 2 included in the primary color sub-pixel S1 are disposed in the white sub-pixel region W1 where the white sub-pixel W2 is located, and the other part of the plurality of light-shielding patterns 2 are disposed in the primary color sub-pixel region P1 corresponding to the primary color sub-pixel S1, so that the area of the opening of the white sub-pixel W2 may be effectively reduced, and an area of an opening of the primary color sub-pixel S1 adjacent to the white sub-pixel W2 may be increased. It is beneficial to reduce a ratio of an area occupied by the plurality of white sub-pixels W2 to a total area occupied by the plurality of primary color sub-pixels S1 in the array substrate 100. Furthermore, a ratio between brightness of white light displayed by the plurality of white sub-pixels W2 and brightness of white light displayed by the plurality of primary color sub-pixels S1 together is reduced, so that the brightness specification of the white light is avoided being exceeded, and the waste of the white light is reduced and even avoided. Moreover, in a case where the array substrate 100 is applied to an LCD, image quality of a single color image displayed by the LCD may be effectively improved.
In addition, on the basis that in the column direction Y, the part of the plurality of light-shielding patterns 2 of the primary color sub-pixel S1 adjacent to the white sub-pixel W2 are disposed in the white sub-pixel region W1 where the white sub-pixel W2 is located, dimensions of the white sub-pixel W1 and the primary color sub-pixel S1 in the row direction X may be reduced, and dimensions of two primary color sub-pixels S1 disposed on two opposite sides (the two opposite sides in the row direction X) of the primary color sub-pixel S1 in the row direction X are increased. That is, areas of openings of the two primary color sub-pixels S1 are increased, so that the ratio of the area occupied by the plurality of white sub-pixels W2 to the total area occupied by the plurality of primary color sub-pixels S1 in the array substrate 100 may be further reduced, the waste of the white light is further reduced or even avoided, display brightness of the plurality of primary color sub-pixels S1 is improved, and the image quality of the single color image displayed by the LCD may be further improved.
In some embodiments, as shown in
In some examples, as shown in
This means that, in the row direction X, thin film transistors 21 in multiple sub-pixels in a same row may be electrically connected to a same gate line GL; in the column direction Y, thin film transistors 21 in multiple sub-pixels in a same column may be electrically connected to a same data line DL.
An arrangement of the gate line GL, the data line DL and the thin film transistor 21 includes various types, the arrangement is related to a structure of the thin film transistor 21 (the thin film transistor 21 is a single-gate transistor or a double-gate transistor). Here, in an example where the thin film transistor 21 is the single-gate transistor, the arrangement of the three is schematically described.
For example, as shown in
For another example, every two gate lines GL and pluralities of thin film transistors 21 in two rows are alternately arranged in sequence, and each data line DL and the plurality of thin film transistors 21 in the same column may also be alternately arranged in sequence. That is, the plurality of thin film transistors 21 in the same row may be adjacent to one gate line GL, and the plurality of thin film transistors 21 in the same column may be adjacent to two data lines DL.
In some examples, as shown in
Here, there exits an example where in the column direction Y, the two primary color sub-pixels S1 adjacent to the white sub-pixel W2 are both green sub-pixels G2.
For example, as shown in
In this case, the thin film transistor 21 may occupy a portion of the white sub-pixel W2, so that the area of the opening of the white sub-pixel W2 is reduced, and an area of an opening of the green sub-pixel G2 is increased. In this way, the ratio of the area occupied by the white sub-pixel to the total area occupied by the red sub-pixel, the green sub-pixel and the blue sub-pixel may be effectively adjusted.
It will be noted that, in this case, as shown in
For example, as shown in
In this way, the portion GL1, passing through the green sub-pixel G2, of the gate line GL may occupy a portion of the white sub-pixel W2, so as to reduce the area of the opening of the white sub-pixel W2. Moreover, on the basis that the portion GL1, passing through the green sub-pixel G2, of the gate line GL is bent toward the white sub-pixel W2, the thin film transistor 21 in the green sub-pixel G2 is shifted toward the white sub-pixel W2 accordingly, so that a dimension of the area of the opening of the green sub-pixel G2 is increased. In this way, it may be ensured an adjusting effect on the ratio of the area occupied by the white sub-pixel W2 to the total area occupied by the red sub-pixel R2, the green sub-pixel G2 and the blue sub-pixel B2.
It will be noted that, in this case, as shown in
For example, as shown in
In this way, it may further ensure the adjusting effect on the ratio of the area occupied by the white sub-pixel W2 to the total area occupied by the red sub-pixel R2, the green sub-pixel G2 and the blue sub-pixel B2, and in turn, the effect of improving the image quality of the single color image displayed by the LCD to which the array substrate 100 is applied is ensured.
The thin film transistor 21 includes various types. For example, a thin film transistor 21 in at least one sub-pixel S is a top-gate thin film transistor. For another example, a thin film transistor 21 in at least one sub-pixel S is a bottom-gate thin film transistor. Here, in some embodiments of the present disclosure, the thin film transistors 21 in the plurality of sub-pixels S included in the array substrate 100 are all top-gate thin film transistors.
In some examples, as shown in
It will be noted that, the “same layer” mentioned herein refers to a layer structure formed by a film layer for forming specific patterns by a same film forming process and then by one patterning process using a same mask. Depending on different specific patterns, a patterning process may include several exposure, development or etching processes, and the specific patterns in the formed layer structure may be continuous or discontinuous, and these specific patterns may also be at different heights or have different thicknesses. In this way, the plurality of data lines DL and sources 213 and drains 214 of the plurality of thin film transistors 21 may be formed simultaneously, which is beneficial to simplifying the manufacturing process of the array substrate 100.
A shape of an orthogonal projection of the active layer 211 on the first substrate 1 includes various types. For example, as shown in
An opening direction of the active layer 211 may be selectively set according to actual needs, which is not limited in the present disclosure.
For example, opening directions of active layers 211 of all thin film transistors 21 in the array substrate 100 are in a same direction. In this way, it is beneficial to reduce the difficulty of manufacturing the array substrate 100.
In addition, as shown in
In some embodiments, as shown in
In some embodiments, in the plurality of primary color sub-pixels S1 included in the array substrate 100, a ratio of areas of openings of the first color sub-pixel S11, the second color sub-pixel S12, the third color sub-pixel S13 and the white sub-pixel W2 is in a range of (0.8 to 1.2):(0.8 to 1.2):(0.8 to 1.2):(0.4 to 0.8).
Here, in the column direction Y, the two primary color sub-pixels S1 adjacent to the white sub-pixel W2 are both second color sub-pixels S12, and in the row direction X, a first color sub-pixel S11 and a third color sub-pixel S13 are respectively disposed on two opposite sides of the second color sub-pixel S12. In the column direction Y, a part of light-shielding patterns 2 included in a second color sub-pixel S12 adjacent to the white sub-pixel W2 are disposed in the white sub-pixel region W1 where the white sub-pixel W2 is located; alternatively, based on this, dimensions of the white sub-pixel W1 and the second color sub-pixel S12 in the row direction X are reduced, and dimensions of the first color sub-pixel S11 and the third color sub-pixel S13 in the row direction X are increased, so that the ratio of the areas of the openings the first color sub-pixel S11, the second color sub-pixel S12, the third color sub-pixel S13 and the white sub-pixel W2 is made to be within the above range, and the ratio between the brightness of the white light displayed by the plurality of white sub-pixels W2 and the brightness of the white light displayed by the plurality of primary color sub-pixels S1 together is in a range of 2:5 to 6:5, inclusive. In this way, it may reduce or even avoid the waste of white light. Moreover, it is beneficial to improve the image quality of the single color image displayed by the LCD to which the above-mentioned array substrate 100 is applied.
For example, the ratio of the areas of the openings of the first color sub-pixel S11, the second color sub-pixel S12, the third color sub-pixel S13 and the white sub-pixel W2 may be 1:1:1:½, 1:1:1: 27/50, 1:1:1: 11/20 or 1:1:1:⅔.
It will be noted that each numerical value in the above proportional range is only for representing a degree of fluctuation compared to the numerical value 1, and does not represent an actual value of an area of an opening of each sub-pixel.
In the following, by considering an example where the first color sub-pixel S11 includes the red sub-pixel R2, the second color sub-pixel S12 includes the green sub-pixel G2, and the third color sub-pixel S13 includes the blue sub-pixel B2, a dimension relationship between the three and the white sub-pixel W2 will be schematically illustrated. As shown in
In some examples, as shown in
In this way, it may be ensured that the areas of the openings of the red sub-pixel R2, the green sub-pixel G2 and the blue sub-pixel B2 are equal or substantially equal, and the areas of the openings of the three are greater than the area of the opening of the white sub-pixel W2.
It will be noted that a dimension of an opening of each sub-pixel S in the row direction X, for example, may refer to a maximum dimension in the row direction X, or may refer to a minimum dimension in the row direction X, or may refer to an average dimension in the row direction X.
In some examples, in the row direction X, a ratio of the dimension LRX of the opening OR of the red sub-pixel R2, the dimension LGX of the opening OG of the green sub-pixel G2, the dimension LBX of the opening OB of the blue sub-pixel B2 and the dimension LWX of the opening OW of the white sub-pixel W2 is in a range of (1.4 to 1.5):(1.2 to 1.4):(1.4 to 1.5):1; in the column direction Y, a ratio of the dimension LRY of the opening OR of the red sub-pixel R2, the dimension LGY of the opening OG of the green sub-pixel G2, the dimension LBY of the opening OB of the blue sub-pixel B2 and the dimension LWY of the opening OW of the white sub-pixel W2 is in a range of (1.2 to 1.3):(1.3 to 1.8):(1.2 to 1.3):1.
For example, the ratio of LRX, LGX, LBX, and LWX may be 1.4:1.2:1.4:1, 1.42:1.23:1.45:1, or 1.5:1.4:1.5:1. For example, LRX may be 22 μm, LGX may be 21 μm, LBX may be 22 μm, and LWX may be 15 μm.
For example, the ratio of LRY, LGY, LBY, and LWY may be 1.2:1.3:1.2:1, 1.25:1.4:1.26:1, or 1.3:1.8:1.3:1. For example, LRY may be 50.4 μm, LGY may be 54.6 μm, LBY may be 50.4 μm, and LWY may be 42 μm.
In the present disclosure, by setting the ratio of LRX, LGX, LBX, and LWX in the row direction X and the ratio of LRY, LGY, LBY, and LWY, white point coordinates of the red sub-pixel R2, the green sub-pixel G2 and the blue sub-pixel B2 are ensured while decreasing the brightness of the white light displayed by the white sub-pixel W2 and increasing the brightness of the white light displayed by the red sub-pixel R2, the green sub-pixel G2 and the blue sub-pixel B2 together.

Here, a relationship between the common electrode 3 and the common electrode line VL includes various types, which may be selectively set according to actual needs.
For example, common electrodes 3 may be electrically connected to the common electrode lines VL in one-to-one correspondence. In this way, the number of the common electrode lines VL may be reduced, and in turn, a space ratio of the common electrode lines VL in the array substrate 100 is reduced.
For example, each common electrode 3 may be electrically connected to multiple common electrode lines VL. In this way, in a case where a connection between a common electrode line VL in the multiple common electrode lines VL and the common electrode 3 is abnormal, other common electrode lines VL may also be used to transmit the common voltage signal to the common electrode 3, which is beneficial to improve the reliability between the common electrode 3 and the common electrode lines VL.
A relationship between the common electrode 3 and the sub-pixel S includes various types, which may be selectively set according to actual needs.
For example, the common electrodes 3 and the sub-pixels S are in one-to-one correspondence. That is, each sub-pixel S includes a single common electrode 3. In this way, each sub-pixel S may be provided with a common voltage signal independently, so as to avoid a situation of cross-talk between common voltage signals in different sub-pixels S.
For example, as shown in
Here, the number of the sub-pixels S corresponding to each common electrode 3 may be selectively set according to actual needs. For example, each common electrode 3 may correspond to two sub-pixels S, three sub-pixels S, or four sub-pixels S.
Alternatively, as shown in
In a case where each common electrode 3 corresponds to the multiple sub-pixels S, common electrodes 3 in the plurality of sub-pixels S may be adopt a connection, for example, as shown in
A positional relationship between the pluralities of common electrode lines VL and sub-pixels S includes various types. Here, by considering an example where the plurality of primary color sub-pixels S1 include the plurality of red sub-pixels R2, the plurality of green sub-pixels G2 and the plurality of blue sub-pixels B2, and the arrangement between the pluralities of primary color sub-pixels S1 and white sub-pixels W2 is as shown in
A positional relationship between the pluralities of common electrode lines VL and common electrodes 3 includes various types. For example, as shown in
By providing the common electrode lines VL and the data lines DL in the same layer, the common electrode lines VL and the data lines DL may be manufactured in a single pattern process simultaneously, which is beneficial to simplify the manufacturing process of the array substrate 100. Moreover, since the common electrode lines VL and the data lines DL have a same extending direction, by providing the common electrode lines VL and the data lines DL in the same layer, a case where the common electrode lines VL and the data lines DL cross to cause a short circuit may be avoided, in addition, the number of film layers included in the array substrate 100 may be reduced, so as to avoid increasing a thickness of the array substrate 100.
In some examples, as shown in
Here, ratios of the dimension LVL of each common electrode line VL in the direction perpendicular to the column direction Y and dimensions LDL of different data lines DL in the direction perpendicular to the column direction Y may be same or different.
For example, the ratios of the dimension of each common electrode line VL in the direction perpendicular to the column direction Y and the dimensions of the different data lines DL in the direction perpendicular to the column direction Y are the same. In this case, the ratio may be, for example, 1:2, 1: 3/2 or 1:1.
For example, the ratios of the dimension LVL of each common electrode line VL in the direction perpendicular to the column direction Y and the dimensions LDL of the different data lines DL in the direction perpendicular to the column direction Y are different. For example, as shown in
It will be noted that the dimension LVL of each common electrode line VL in the direction perpendicular to the column direction Y may refer to, for example, an average dimension LVL of each common electrode line VL in the direction perpendicular to the column direction Y, and the dimension LDL of the data line DL in the direction perpendicular to the column direction Y may refer to, for example, an average dimension LDL of each data line DL in the direction Y perpendicular to the column.
In some examples, the common electrode 3 also serves as a touch electrode, and the common electrode line VL also serves as a touch signal line.
Base on this, the array substrate 100 provided by some embodiments of the present disclosure may be applied to a LCD of a self-capacitance mode, and the LCD may realize a display function and a touch control function in different time periods.
In a display period, the common electrode line VL may be used to transmit a common voltage signal to the common electrode 3.
In a touch period, the common electrode line VL may be used to input a signal (e.g., a touch detection signal) to the common electrode 3, and output a signal (e.g., a capacitance signal) from the common electrode 3. In this case, when a human body does not touch the LCD, a capacitance provided by each common electrode is at a fixed value; and when the human body touches the LCD, a capacitance provided by a common electrode corresponding to a position touched by the human body is at a sum of the fixed value and a capacitance value of the human body, and then capacitance values of all common electrodes may be transmitted by the common electrode lines VL, so that the position touched by the human body may be determined by detecting a change of a capacitance value of each common electrode 3.

In some examples, as shown in
For example, a pixel electrode 4 in the white sub-pixel W2 has one slit 41, and a pixel electrode 4 in each primary color sub-pixel S1 has two slits 41.
By providing the at least one slit 41 in the pixel electrode 4, in a case where in the same sub-pixel S, the common electrode 3 has a common voltage signal and the pixel electrode 4 has a data voltage signal, it is possible to make a portion of an electric field generated between the common electrode 3 and the pixel electrode 4 on a side of the pixel electrode 4 away from the common electrode 3 through the at least one slit. In the case where the array substrate 100 is applied to the LCD, the portion of the electric field on the side of the pixel electrode 4 away from the common electrode 3 may be used to drive liquid crystal molecules to rotate, so that the LCD may realize image display.
In some examples, materials of the common electrode 3 and the pixel electrode 4 may adopt a conductive material with a high light transmittance. For example, the conductive material may be indium tin oxide (ITO), indium zinc oxide (IZO) or the like. In this way, it may avoid affecting the display effect of the LCD.

In some examples, in a case where the plurality of primary color sub-pixels S1 include the plurality of red sub-pixels R2, the plurality of green sub-pixels G2, and the plurality of blue sub-pixels B2, as shown in
In the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the white sub-pixel W2 is the same or substantially the same as the dimension L41X of the slit 41 of the pixel electrode 4 in the green sub-pixel G2; and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the white sub-pixel W2 is the same or substantially the same as the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the green sub-pixel G2. In this way, the data lines DL may be prevented from having a folded line shape.
For example, in the row direction X, the ratio of the dimension L41X of the slit 41 and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the white sub-pixel W2 is in a range of (2.4 to 2.8):(2.0 to 2.7). In this case, the ratio of the dimension L41X of the slit 41 and the dimension L42X of the strip-shaped sub-electrode 42 in the pixel electrode 4 of the green sub-pixel G2 may also be in the range of (2.4 to 2.8):(2.0 to 2.7).
For example, in the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the white sub-pixel W2 is 2.4 μm, and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the white sub-pixel W2 is 2.0 μm, in this case, the ratio between the two is 2.4:2.0. For another example, in the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the white sub-pixel W2 is 2.8 μm, and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the white sub-pixel W2 is 2.7 μm, in this case, the ratio between the two is 2.8:2.7. For yet another example, in the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the white sub-pixel W2 is 2.6 μm, and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the white sub-pixel W2 is 2.5 μm, in this case, the ratio between the two is 2.6:2.5.
In some examples, in the case where the plurality of primary color sub-pixels S1 include the plurality of red sub-pixels R2, the plurality of green sub-pixels G2 and the plurality of blue sub-pixels B2, as shown in
In the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the red sub-pixel R2 is the same or substantially the same as the dimension L41X of the slit 41 of the pixel electrode 4 in the blue sub-pixel B2; and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the red sub-pixel R2 is the same or substantially the same as the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the blue sub-pixel B2. In this way, the data lines DL may be prevented from having a folded line shape.
For example, in the row direction X, the ratio between the dimension L41X of the slit 41 and the dimension L42X of the stripe-shaped sub-electrode 42 of the pixel electrode 4 in the red sub-pixel R2 is in a range of (2.2 to 2.8):(2.0 to 2.5). In this case, the ratio between the dimension L41X of the slit 41 and the dimension L42X of the stripe-shaped sub-electrode 42 of the pixel electrode 4 in the blue sub-pixel B2 may also be in the range of (2.2 to 2.8):(2.0 to 2.5).
For example, in the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the red sub-pixel R2 is 2.8 μm, and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the red sub-pixel R2 is 2.0 μm, in this case, the ratio between the two is 2.8:2.0. For another example, in the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the red sub-pixel R2 is 2.2 μm, and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the red sub-pixel R2 is 2.5 μm, in this case, the ratio between the two is 2.2:2.5. For yet another example, in the row direction X, the dimension L41X of the slit 41 of the pixel electrode 4 in the red sub-pixel R2 is 2.4 μm, and the dimension L42X of the strip-shaped sub-electrode 42 of the pixel electrode 4 in the red sub-pixel R2 is 2.3 μm, in this case, the ratio between the two is 2.4:2.3.
By setting a dimension relationship between the slit 41 and the strip-shaped sub-electrode 42 of the pixel electrode 4 in each sub-pixel S in the row direction X, it may be ensured that the portion of the electric field generated on the side of the pixel electrode 4 away from the common electrode 3 is a parallel electric field or substantially a parallel electric field. In this way, in the case where the array substrate 100 is applied to the LCD, it may be ensured that the liquid crystal molecules in the LCD may generate an angular deflection in a direction parallel to a plane where the LCD is located due to an action of the portion of the electric field, so as to change polarization state of polarized light.
It will be noted that, in the row direction X, the dimension L41X of the slit 41 and the dimension L42X of the strip-shaped sub-electrode 42 of each pixel electrode 4, for example, refer to maximum dimensions in the row direction X, or refer to minimum dimensions in the row direction, or refer to average dimensions in the row direction X.
Some embodiments of the present disclosure provide a display apparatus 1000. As shown in
In some examples, the liquid crystal layer 300 includes a plurality of liquid crystal molecules. During the display process of the display apparatus 1000, the electric field generated between the pixel electrodes 4 and the common electrodes 3 in the array substrate 100 may drive the liquid crystal molecules in the liquid crystal layer 300 to rotate, so that the display apparatus 1000 may achieve image display.
In some examples, as shown in
The beneficial effects that may be achieved by the display apparatus 1000 provided in some embodiments of the present disclosure are the same as the beneficial effects that may be achieved by the array substrate 100 provided in some of the above embodiments, and will not be repeated herein.
It will be noted that in a case where the ratio between the brightness of the white light displayed by the plurality of white sub-pixels W2 and the brightness of the white light displayed by the plurality of primary color sub-pixels S1 together in the array substrate 100 is reduced, display brightness of the display apparatus 1000 may still be improved. For example, in the display apparatus 1000 provided in some embodiments of the present disclosure, the display brightness may be improved by 3% compared with a common LCD.
In addition, in a case where the array substrate 100 provided in some of the above embodiments is applied to the display apparatus 1000, it is beneficial to improve resistance to misalignment between the array substrate 100 and the counter substrate 200. For example, in a case where an alignment shift occurs between the array substrate 100 and the counter substrate 200, the display apparatus 1000 provided in some embodiments of the present disclosure may be improved by 2% compared with the common LCD.
In some embodiments, as shown in
Here, the second substrate 5 may have, for example, a same structure as the first substrate 1.
In some embodiments, as shown in
In some examples, the black matrix 6 is configured to shield the plurality of gate lines GL, the plurality of data lines DL and the plurality of thin film transistors 21 in the array substrate 100.
For example, orthogonal projections of the plurality of thin film transistors 21 on the first substrate 1 may be within a range of an orthogonal projection of the black matrix 6 on the first substrate 1. In this way, the black matrix 6 may be used to block the external light emitted to the plurality of thin film transistors 21, so as to prevent the external light from adversely affecting the performance of the plurality of thin film transistors 21.
For example, orthogonal projections of the plurality of gate lines GL and the plurality of data lines DL on the first substrate 1 may be located within the range of the orthogonal projection of the black matrix 6 on the first substrate 1. In this way, the black matrix 6 may be used to block the external light emitted to the plurality of gate lines GL and the plurality of data lines DL, so as to avoid reflection of the external light off the plurality of gate lines GL and the plurality of data lines DL, which is beneficial to make the display apparatus 1000 have a high contrast ratio.
As shown in
In some embodiments, as shown in
Here, in an example, the plurality of primary color sub-pixels S1 in the array substrate 100 include the plurality of red sub-pixels R2, the plurality of green sub-pixels G2 and the plurality of blue sub-pixels B2, accordingly, the color filter layer 7 includes red filter portions 71 respectively corresponding to the plurality of red sub-pixels R2, green filter portions 72 respectively corresponding to the plurality of green sub-pixels G2, and blue filter portions 73 respectively corresponding to the plurality of blue sub-pixels B2.
It will be noted that a surface of the color filter layer 7 away from the second substrate 5 and a surface of the black matrix 6 away from the second substrate 5 may be flush with each other. Alternatively, compared with the second substrate 5, the surface of the color filter layer 7 away from the second substrate 5 is higher or lower than the surface of the black matrix 6 away from the second substrate 5.
In some embodiments, as shown in
There is no need to provide the color filter layer 7 in the plurality of first openings K1 corresponding to the plurality of white sub-pixels W2, therefore, after the planarization layer 8 is formed, the portion of the planarization layer 8 may naturally fall into the plurality of first openings K1, so as to fill spaces in the plurality of first openings K1. In this way, a thickness of a portion of the liquid crystal layer 300 (i.e., a dimension in a direction perpendicular to the second substrate 5) corresponding to the plurality of second openings K2 and a thickness of a portion (i.e., a dimension in the direction perpendicular to the second substrate 5) corresponding to the plurality of first openings K1 are equal or substantially equal, which is beneficial to avoid affecting the light output effect.
In some embodiments, the display apparatus 1000 further includes a plurality of separation spacers disposed between the array substrate 100 and the counter substrate 200.
In some examples, the plurality of separation spacers are configured to support the array substrate 100 and the counter substrate 200, so that distances between of the array substrate 100 and the counter substrate 200 at different positions are consistent or substantially consistent, so as to avoid affecting the display effect of the display apparatus 1000.
In some examples, in a case where in the column direction Y, the part of the light-shielding patterns 2 of the primary color sub-pixel S1 adjacent to the white sub-pixel W2 are disposed in the white sub-pixel region W1 where the white sub-pixel W2 is located, an area of a portion of the white sub-pixel region W1 shielded by the black matrix 6 is increased. Based on this, the separation spacers may be disposed in positions corresponding to the white sub-pixel regions W1, so that the separation spacers may be well provided while avoiding an additional increase in an area of the portion blocked by the black matrix 6, and in tum, it is avoided to reduce the aperture ratio of the display apparatus 1000.
In some examples, as shown in
For example, as shown in
In some embodiments, in a case where the common electrodes 3 in the array substrate 100 also serve as the touch electrodes, and the common electrode lines VL also serve as the touch signal lines, the display apparatus 1000 further includes a touch and display driver integration (TDDI) chip disposed in a bezel area of the array substrate 100.
In some examples, the TDDI chip is configured to transmit the common voltage signals to the common electrodes 3 of the array substrate 100 through the common electrode lines VL in the display period of the display apparatus 1000, so that the common electrodes 3 may cooperate with the pixel electrodes 4 to make the display apparatus 1000 display images. The TDDI chip is further configured to transmit the touch control signals to the common electrodes 3 through the common electrode lines VL in the touch period of the display apparatus 1000, so as to realize the touch function by using the common electrodes 3.
By providing the TDDI chip, different signals may be transmitted to the common electrodes 3 in different periods, so that the display apparatus 1000 may realize different functions. That is, the touch function and the display function are integrated together, which is beneficial to simplify the structure of the display apparatus 1000 and simplify the manufacturing process of the display apparatus 1000.
In some embodiments, the display apparatus 1000 may be any apparatus that displays an image whether in motion (e.g., a video) or stationary (e.g., a still image), and whether textual or graphical.
