CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to Taiwan Patent Application No. 104135109 filed in the Taiwan Patent Office on Oct. 26, 2015, the entire content of which is incorporated herein by reference.
BACKGROUND OF THE DISCLOSURE
This application relates to a display technology, and in particular, to a display panel.
In order to solve the side-view color washout problem of a display apparatus, a single subpixel of the display apparatus is usually divided into two areas, and appropriate circuitry is applied to drive the two areas of the single subpixel with different pixel voltages. With this arrangement, the single subpixel displays two different gray level-to-brightness curves, which serves to alleviate the color washout problem.
In order to meet consumer expectations of picture clarity, high resolution is a design goal in the development of a display apparatus. However, if the foregoing single subpixel area division technology is adopted in a display apparatus with high resolution, transmittance of the display apparatus is reduced.

DETAILED DESCRIPTION OF THE DISCLOSURE
In order to make the description of this disclosure more comprehensive, implementation aspects and specific embodiments of the present disclosure are illustratively described below, but are not intended to be the sole means or form of implementing or applying the specific embodiments of the present disclosure. Implementation manners cover features of a plurality of specific embodiments, and method steps and a sequence thereof used for constructing and operating the specific embodiments. However, other specific embodiments may be also used to achieve the same or equivalent function and sequence of steps.
Unless otherwise defined in this specification, meanings of scientific and technical terms used herein are the same as the common meanings that are understood by a person of ordinary skill in the art. Use of a singular noun used in this specification covers a plural form of the noun, and a plural noun also covers a singular form of the noun, except when such interpretation would give rise to a contextual conflict.
FIG. 1A is a schematic diagram of a display panel according to an embodiment of the present disclosure. The display panel 100 includes a driver (not shown in the figure), 3*X data lines D1 to Dx, Y scan lines G1 to Gy, and X*Y pixels P11 to Pxy. The X and Y are positive integers. Each pixel includes a first color subpixel SP1, a second color subpixel SP2 and a third color subpixel SP3. Furthermore, each pixel includes a switch T electrically connecting to the data line and scan line respectively. The driver is configured to receive display data with X*Y resolution; the 3*X data lines D1 to Dx are electrically connected to the driver and are configured to receive a plurality of pixel voltages; the X*Y pixels P11 to Pxy are electrically connected to the data lines D1 to Dx and the scan lines G1 to Gy; and when all gray levels of a first color display data set happen to be identical to one another and lower than a first threshold value, the pixel voltages of the corresponding plurality of first color sub-pixels are nevertheless not identical.
The disclosure uses a driver to enable, when all gray levels of a first color display data set happen to be identical to one another and lower than a first threshold value, the pixel voltages of the corresponding plurality of first color pixels are nevertheless not identical, thereby alleviating the color washout problem. An original structure of a pixel does not need to be changed in the display panel 100 of the embodiment of the disclosure. Therefore, as compared with the prior art, the disclosure improves transmittance of a display panel.
FIG. 1B is a schematic diagram of a driver of a display panel according to another embodiment of the disclosure. As shown in the figure, a driver 110 includes a first gamma lookup table (LUT1) 112 and a second gamma lookup table (LUT2) 114. In operation, the first gamma lookup table (LUT1) 112 is configured to separately receive the display data and provide a plurality of first pixel voltages. The second gamma lookup table (LUT2) 114 is configured to separately receive the display data and provide a plurality of second pixel voltages. Therefore the driver 110 produces a first pixel voltage and a second pixel voltage corresponding to each gray level in the display data. In the embodiment shown in FIG. 1A, a pixel in an odd row receives one of the first pixel voltages, and a pixel in an even row receives one of the second pixel voltages. For example, a pixel in a first row R1 receives one of the first pixel voltages, and a pixel in a second row R2 receives one of the second pixel voltages. As compared with the prior art in which a single subpixel is divided into two areas, the present disclosure, rather than changing an original structure of a pixel, instead uses two pixels that are located at a same column and at two adjacent rows. These two adjacent pixels in column direction are regarded as a main pixel M and a secondary pixel S. For example, a pixel in the first row R1 is regarded as a main pixel M, and a pixel in the second row R2 is regarded as a secondary pixel S, and the driver 110 separately provides a first pixel voltage to the main pixel M and a second pixel voltage to the secondary pixel S, so as to enable the two pixels to display with different voltage-to-brightness curves, thereby alleviating the color washout problem. Furthermore, the pixels in the first row R1 and the pixels in the second row R2 at the same column receive pixel voltages corresponding to different display data. For example, the pixel P11 receives the first pixel voltage corresponding to a first display data and the pixel P21 receives the second pixel voltage corresponding to a second display data. In other words, any pixel receiving the first pixel voltage is regards as main pixel M and any pixel receiving the second pixel voltage is regards as secondary pixel S.
FIG. 1C is a schematic structural diagram of a display panel according to another embodiment of the disclosure. Each of the X*Y pixels P11 to Pxy shown in FIG. 1A includes a first color subpixel SP1, a second color subpixel SP2, and a third color subpixel SP3; the first color subpixels SP1 and the third color subpixels SP3 in odd rows receive first pixel voltages; the second color subpixels SP2 in the odd rows receive second pixel voltages; the first color subpixels SP1 and the third color subpixels SP3 in even rows receive the second pixel voltages; and the second color subpixels SP2 in the even rows receive the first pixel voltages. As compared with the prior art in which a single subpixel is divided into two areas, rather than change an original structure of a subpixel, the disclosure uses two subpixels located in two adjacent rows as the main subpixel m and a secondary subpixel s, and a driver 110 separately provides a first pixel voltage and a second pixel voltage to the main subpixel m and the secondary subpixel s, so as to enable the two subpixels to be displayed with different brightnesses, thereby alleviating the color washout problem.
FIG. 2A is a schematic diagram of a display panel according to yet another embodiment of the disclosure. As shown in the figure, X*Y pixels P11 to Pxy include a first pixel and a second pixel adjacent to each other; the first pixel and the second pixel receive a first pixel voltage; and other pixels adjacent to the first pixel and the second pixel receive a second pixel voltage. For example, X*Y pixels P11 to Pxy include a pixel P11 and a pixel P12 adjacent to each other; the pixel P11 and the pixel P12 receive a first pixel voltage; and other pixels (such as pixels P13, P21, and P22) adjacent to the pixel P11 and the pixel P12 receive a second pixel voltage. Furthermore, any pixel receiving the first pixel voltage is regards as main pixel M and any pixel receiving the second pixel voltage is regards as secondary pixel S. Further referring to FIG. 2A, a first pixel P11 and a second pixel P12 in a first row R1 separately receive the first pixel voltage; a third pixel P13 and a fourth pixel P14 in the first row R1 separately receive the second pixel voltage; a first pixel P21 and a second pixel P22 in a second row R2 separately receive the second pixel voltage; a third pixel P23 and a fourth pixel P24 separately receive the first pixel voltage; and the display panel is expanded according to pixel arrays of the foregoing pixels P11 to P24.
FIG. 2B is a schematic structural diagram of a display panel according to still another embodiment of the disclosure. Each of X*Y pixels P11 to Pxy includes a first color subpixel SP1, a second color subpixel SP2, and a third color subpixel SP3; the first color subpixels SP1 and the third color subpixels SP3 receive a voltage from either the first pixel voltages or the second pixel voltages, and the second subpixels SP2 receive a voltage from the other of the first pixel voltages and the second pixel voltages. In other words, any subpixel receiving the first pixel voltage is regards as main subpixel m and any subpixel receiving the second pixel voltage is regards as secondary subpixel s. For example, first color subpixels SP1 and third color subpixels SP3 in a pixel P11 and a pixel P12 receive first pixel voltages, and second color subpixels SP2 receive second pixel voltages; first color subpixels SP1 and third color subpixels SP3 in a pixel P13 and a pixel P14 receive the second pixel voltages, and second color subpixels SP2 receive the first pixel voltages; first color subpixels SP1 and third color subpixels SP3 in a pixel P21 and a pixel P22 receive the second pixel voltages, and second color subpixels SP2 receive the first pixel voltages; first color subpixels SP1 and third color subpixels SP3 in a pixel P23 and a pixel P24 receive the first pixel voltages, and second color subpixels SP2 receive the second pixel voltages; and the display panel is expanded according to pixel arrays of the foregoing pixels P11 to P24. In other words, one of any two adjacent subpixels in a same column receives a voltage from the first pixel voltages, and the other subpixel receives a voltage from the second pixel voltages.
FIG. 3A is a schematic diagram of a display panel according to another embodiment of the disclosure. As shown in the figure, X*Y pixels P11 to Pxy include a first pixel and a second pixel adjacent to each other; the first pixel receives a voltage from the first pixel voltages; and the second pixel receives a voltage from the second pixel voltages. For example, X*Y pixels P11 to Pxy include a pixel P11 and a pixel P12 adjacent to each other; the pixel P11 receives a voltage from the first pixel voltages, and the pixel P12 receives a voltage from the second pixel voltages; a pixel P21 adjacent to the pixel P11 receives a voltage from the second pixel voltages, and a pixel P22 adjacent to the pixel P12 receives a voltage from the first pixel voltages; and the display panel is expanded according to pixel arrays of the foregoing pixels P11 to P22.
FIG. 3B is a schematic structural diagram of a display panel according to yet another embodiment of the disclosure. As shown in the figure, each of X*Y pixels P11 to Pxy includes the first color subpixels SP1, the second color subpixels SP2 and the third color subpixels SP3; subpixels corresponding to odd columns and odd rows receive first pixel voltages; subpixels corresponding to even columns and even rows receive first pixel voltages; subpixels corresponding to the odd columns and the even rows receive second pixel voltages; and subpixels corresponding to the even columns and the odd rows receive second pixel voltages.
FIG. 4 is a schematic diagram of a curve of gray-level versus voltage according to an embodiment of the disclosure. In a display panel of the disclosure, two pixels (or two subpixels) that are located at a same column and at two adjacent rows separately receive a voltage from the first pixel voltages and a voltage from the second pixel voltages, respectively. Therefore, from the perspective of the overall frame image, two pixels (or two subpixels) that are located at a same column and at two adjacent rows are displayed with different brightness, and a brightness difference between the two pixels (or two subpixels) causes a stripe phenomenon on the frame image. Referring to FIG. 3A and FIG. 3B, any two adjacent pixels (or any two adjacent subpixels) in a display panel separately receive different pixel voltages, which might cause a broken color phenomenon when a frame image is displayed. In this situation, the display is unable to display the color that is intended. The foregoing problem causes poor user perception and reduced resolution.
In order to solve the foregoing problem, referring to FIG. 1B and FIG. 4 together, when all gray levels of a first color display data set received by a driver 100 happen to be identical to one another and higher than a threshold value GL1, the driver 110 provides identical pixel voltages to the X*Y pixels P11 to Pxy through data lines D1 to Dn. For example, when all gray levels of a first color display data set received by a first gamma lookup table (LUT1) 112 and a second gamma lookup table (LUT2) 114 of a driver 110 happen to be identical to one another and higher than or equal to a gray level of L192 (using a gray level range of L0 to L255 as an example in this embodiment), a first pixel voltage VM provided by the first gamma lookup table (LUT1) 112 is equal to a second pixel voltage VS provided by the second gamma lookup table (LUT2) 114, and in this way, adjacent pixels (subpixels) are displayed with a same brightness, so as to ameliorate the stripe phenomenon and color shift phenomenon introduced above, and improve the viewing experience of a user of the display panel. However, the disclosure is not limited to the foregoing threshold value, and the foregoing threshold value can be adaptively selected according to actual requirements when the disclosure is implemented.
FIG. 5 is a data verification diagram of the embodiment shown in FIG. 4 according to another embodiment of the disclosure. As shown in the figure, a curve C1 is a brightness curve of a front view of a display panel; a curve C2 is a brightness curve of a side view of the display panel when different pixel voltages are adopted in the disclosure; and a curve C3 is a brightness curve of a side view of the display panel in a case in which pixel voltages are derived from the same gray level-to-voltage curve when a gray level is high in the disclosure. First, it can be deduced from a comparison between the curve C1 and the curve C2 that a difference between the curve C1 and the curve C2 is stable. Therefore, no matter whether the displayed colors are red, green, blue, or otherwise, the brightness levels synthesized by the curve C1 and the curve C2 are stable, and a situation in which any particular color is spuriously brighter is avoided. In this way, a color washout problem can be prevented. Second, it can be deduced from a comparison between the curve C2 and the curve C3 that even if the curve C3 indicates that the pixel voltages are derived from the same gray level-to-voltage curve when the gray level is high, the difference between the curve C3 and the curve C2 indicating that the pixel voltages are not adjusted is very small. Therefore, deriving the pixel voltages from the same gray level-to-voltage curve when the gray level is high can also solve the color washout problem, and can further improve a stripe phenomenon and a color shift phenomenon of an overall frame and improve viewing experience of a user on a display panel.
FIG. 6 is a schematic diagram of a curve of gray-level versus voltage according to yet another embodiment of the disclosure. To solve problems of the foregoing stripe phenomenon and color shift phenomenon of an overall frame, besides the manner of adjusting the pixel voltages to be derived from the same gray level-to-voltage curve when the gray level of the display is high as shown in FIG. 4, the pixel voltages can be further derived from the same gray level-to-voltage curve when the gray level of the display is low. Referring to FIG. 1B and FIG. 6 together, when all gray levels of a first color display data received by a driver 110 are lower than a threshold value GL2, the driver 110 provides an identical pixel voltage to the X*Y pixels P11 to Pxy through data lines D1 to Dn. For example, when all gray levels of a first color display data set received by a first gamma lookup table (LUT1) 112 and a second gamma lookup table (LUT2) 114 of a driver 110 are lower than or equal to a gray level of L32, a first pixel voltage VM provided by the first gamma lookup table (LUT1) 112 is equal to a second pixel voltage VS provided by the second gamma lookup table (LUT2) 114, and in this way, adjacent pixels (subpixels) are displayed with a same brightness, so as to improve a stripe phenomenon and a color shift phenomenon of an overall frame, and improve the viewing experience of a user of the display panel. In another embodiment, the foregoing threshold value may be a gray level of L5 (using a gray level range of L0 to L255 as an example in this embodiment). However, the disclosure is not limited to the foregoing threshold value, and the foregoing threshold value can be adaptively selected according to actual requirements when the disclosure is implemented.
FIG. 7 is a data verification diagram of the embodiment shown in FIG. 6 according to still another embodiment of the disclosure. As shown in the figure, a curve C1 is a brightness curve of a front view of a display panel; a curve C2 is a brightness curve of a side view of the display panel when different pixel voltages are adopted in the disclosure; and a curve C3 is a brightness curve of a side view of the display panel in a case in which pixel voltages are derived from the same gray level-to-voltage curve when a gray level is high or when a gray level is low in the disclosure. It should be noted that the comparison between the curve C1 and the curve C2 is described in the prior embodiment, and is not described herein again. Second, it can be deduced from a comparison between the curve C2 and the curve C3 that even if the curve C3 indicates that the pixel voltages are derived from the same gray level-to-voltage curve when the gray level is high or when the gray level is low, a difference between the curve C3 and the curve C2 indicating that the pixel voltages are not adjusted is very small. Therefore, it can be proved that a manner of adjusting the pixel voltages to be derived from the same gray level-to-voltage curve when the gray level is high or when the gray level is low in the disclosure can also help ameliorate the color washout problem, and can further improve a stripe phenomenon and a color shift phenomenon of an overall frame and improve viewing experience of a user on a display panel.
FIG. 8 is a schematic diagram of a display panel according to an embodiment of the disclosure. FIG. 9 is a schematic diagram of data voltages and reference voltages according to another embodiment of the disclosure. It should be noted that an architecture of a display panel of FIG. 8 is similar to that of FIG. 3B. In order to make the specification of this application concise, the architecture of the display panel of FIG. 8 is not further described herein. In FIG. 8, it can be seen that polarities of main subpixels m in a same scan line are all the same polarities, and polarities of secondary subpixels s are all the same polarities. As for impacts of the foregoing phenomenon, refer to FIG. 9. First, an ideal common voltage Vcom should be maintained at a same voltage value as shown in FIG. 9. However, the polarities of the main subpixels m in the same scan line are all the same polarities, and therefore, once a data voltage provided by a data line D1 is changed to a high level, the common voltage Vcom is pulled towards the positive polarity, so that a voltage of the main subpixels m becomes smaller, and a voltage of the secondary subpixels s becomes larger, causing a gamma curve to change, so as to cause a horizontal crosstalk (H-Crosstalk) phenomenon.
In order to solve the foregoing problem, the disclosure performs different configurations on polarities of data voltages provided by data lines, so as to enable polarities of data signals received by main subpixels m in a same row to include a positive polarity and a negative polarity instead of including a same polarity only, so that a common voltage Vcom is maintained at a same voltage value, thereby further improving an H-Crosstalk phenomenon. Refer to the following FIG. 10A to FIG. 12A for a detailed polarity configuration manner of the data voltages.
FIG. 10A is a schematic diagram of polarity configurations of data voltages according to yet another embodiment of the disclosure. As shown in the figure, polarities of data voltages provided by every four data lines are configured to be a positive polarity (+), a positive polarity (+), a negative polarity (−), and a negative polarity (−). Accordingly, in a same row, polarities of data signals received by a main subpixel m, a secondary subpixel s, a main subpixel m, and a secondary subpixel s are sequentially a positive polarity (+), a positive polarity (+), a negative polarity (−), and a negative polarity (−). FIG. 10B is a schematic diagram of a display panel and polarities of subpixels thereof according to still another embodiment of the disclosure, where polarities of adjacent subpixels in a same column may be different, but the disclosure is not limited thereto, and polarity conversion may be applied by every N rows. FIG. 10B shows a state of a display panel to which the polarity configurations of data voltages in FIG. 10A are applied. It can be seen from FIG. 10B that polarities of data signals received by main subpixels m in a same row include a positive polarity and a negative polarity instead of including a positive polarity only, so that a common voltage Vcom is maintained at a same voltage value, thereby further improving an H-Crosstalk phenomenon.
FIG. 11A is a schematic diagram of polarity configurations of data voltages according to another embodiment of the disclosure. As shown in the figure, polarities of data voltages provided by every eight data lines are configured to be a positive polarity (+), a negative polarity (−), a negative polarity (−), a positive polarity (+), a negative polarity (−), a positive polarity (+), a positive polarity (+), and a negative polarity (−). Accordingly, in a same row, polarities of data signals separately received by main subpixels m and secondary subpixels s arranged in an interlaced manner are sequentially a positive polarity (+), a negative polarity (−), a negative polarity (−), a positive polarity (+), a negative polarity (−), a positive polarity (+), a positive polarity (+), and a negative polarity (−). FIG. 11B is a schematic diagram of a display panel and polarities of subpixels thereof according to yet another embodiment of the disclosure, where polarities of subpixels in a same column may change by every two rows, but the disclosure is not limited thereto, and polarity conversion may be applied by every N rows. FIG. 11B shows a state of a display panel to which the polarity configurations of data voltages in FIG. 11A are applied. It can be seen from FIG. 11B that polarities of data signals received by main subpixels m in a same row include a positive polarity and a negative polarity instead of including a positive polarity only, so that a common voltage Vcom is maintained at a same voltage value, thereby further improving an H-Crosstalk phenomenon.
FIG. 12A is a schematic diagram of polarity configurations of data voltages according to still another embodiment of the disclosure. As shown in the figure, polarities of data voltages provided by every eight data lines are configured to be a positive polarity (+), a positive polarity (+), a positive polarity (+), a positive polarity (+), a negative polarity (−), a negative polarity (−), a negative polarity (−), and a negative polarity (−). Accordingly, in a same row, polarities of data signals separately received by main subpixels m and secondary subpixels s arranged in an interlaced manner are sequentially a positive polarity (+), a positive polarity (+), a positive polarity (+), a positive polarity (+), a negative polarity (−), a negative polarity (−), a negative polarity (−), and a negative polarity (−). FIG. 12B is a schematic diagram of a display panel and polarities of subpixels thereof according to another embodiment of the disclosure, where polarities of subpixels in a same column may change by every two rows, but the disclosure is not limited thereto, and polarity conversion may be applied by every N rows. FIG. 12B shows a state of a display panel to which the polarity configurations of data voltages in FIG. 12A are applied. It can be seen from FIG. 12B that polarities of data signals received by main subpixels m in a same row include a positive polarity and a negative polarity instead of including a positive polarity only, so that a common voltage Vcom is maintained at a same voltage value, thereby further improving an H-Crosstalk phenomenon.
In the embodiments of FIG. 10A to FIG. 12A, data lines at two sides of some subpixels are of the same polarity, for example, in FIG. 10A, data lines D1 and D2 are of the same polarity (+), and data lines D3 and D4 are of the same polarity (−), thus causing vertical crosstalk (V-Crosstalk). In order to improve the V-Crosstalk, the disclosure performs configuration on polarity conversion adopted by data lines, and refer to the following FIG. 13.
FIG. 13 is a schematic diagram of data voltages and reference voltages according to still another embodiment of the disclosure. As shown in the figure, a data line D1 and a data line D2 adopt dot polarity conversion, and data voltages provided by the data line D1 and the data line D2 are periodically converted between a positive polarity and a negative polarity. In a short time period, a voltage value of a common voltage Vcom at a specific time point may be slightly pulled up or pulled down, but, in view of a long time period, an average voltage of the common voltage Vcom remains unchanged. Hence, it can be known that a configuration manner of polarity conversion performed on data lines in the disclosure can surely solve the V-Crosstalk problem. In addition, a cycle of the dot polarity conversion should not be excessively long, so as to prevent a state of liquid crystals from being affected, and further prevent more display problems from being caused. The cycle of the dot polarity conversion adopted in the disclosure is lower than 1 millisecond (ms), and therefore, the average voltage of the common voltage Vcom can remain unchanged on the premise of not affecting the liquid crystals, so as to solve the V-Crosstalk problem. In an embodiment, the disclosure may adopt N-line dot polarity conversion. In order to prevent a cycle of the dot polarity conversion from being excessively long, and further prevent a state of liquid crystals from being affected, the disclosure may adopt 32-line dot polarity conversion or 64-line dot polarity conversion, so as to solve a V-Crosstalk problem. However, the disclosure is not limited to the foregoing value, and the foregoing value can be adaptively selected according to actual requirements when the disclosure is implemented. Furthermore, the first color, the second color and the third color in the abovementioned embodiments of the disclosure, preferred are different from each other, for example, red color, green color, and blue color, but not limited its. For example, the first color subpixel can be red color subpixel, the second color subpixel can be green color subpixel, and the third color subpixel can be blue color subpixel, but not limited its.
It can be seen from the foregoing description of the disclosure that application of the disclosure allows for a display panel that solves the side-view color washout, striping, color shift, H-crosstalk and V-crosstalk problems without the transmittance reduction problem of typical a subpixel area division technology.
Specific embodiments of the disclosure are disclosed in the above description, but are not intended to limit the disclosure to only these embodiments. A person of ordinary skill in the art can understand various variations and modifications to the embodiments without departing from the principle and spirit of the disclosure. Therefore, the protection scope of the disclosure should be subject to the scope defined by the claims.
