In order to make the objects, the technical solutions and the advantages of the present disclosure more apparent, the present disclosure will be described hereinafter in a clear and complete manner in conjunction with the drawings and embodiments.
In the related art, due to the limitation of pixel arrangement, for a same data line, if a first data voltage corresponding to a sub-pixel in a first color is outputted in an nth row, a second data voltage corresponding to a sub-pixel in a second color needs to be outputted in an (n+1)th row, resulting in a voltage swing on the data line and thereby an increase in the power consumption of a display product. Moreover, when a data signal is transmitted from a central processing unit (CPU) to a driving chip, large power consumption also occurs for the display product.
As shown in
For example, the display device includes a display sub-circuitry 30, the display sub-circuitry 30 includes a display region and a peripheral region surrounding the display region, and the plurality of sub-pixels is located in the display region. The data line includes a portion located in the display region and a portion located in the peripheral region, the portion of the data line in the display region is coupled to the plurality of sub-pixels in a same color, and the portion of the data line in the peripheral region is coupled to the driving module 20.
For example, the control module 10 outputs three groups of first data signals, a first group of first data signals corresponds to red sub-pixels, a second group of first data signals corresponds to green sub-pixels, and a third group of first data signals corresponds to blue sub-pixels. For example, the control module 10 transmits a plurality of groups of first data signals to the driving module 20 separately. As shown in
For example, the plurality of sub-pixels is arranged in an array form and includes sub-pixels arranged in a plurality of rows, and at least two sub-pixels in the sub-pixels in each row are in different colors.
For example, the driving module 20 is configured to rearrange the plurality of groups of first data signals to obtain a plurality of groups of second data signals, and each group of second data signals corresponds to sub-pixels in one row. When the sub-pixels in each row are scanned, the driving module 20 writes a group of second data signals corresponding to the sub-pixels in each row into the sub-pixels through the plurality of data lines, so as to achieve a display function of the display device.
For example, the control module 10 includes, but not limited to, an application processor (AP) (also called as a CPU) of a mobile phone.

The driving module is configured to rearrange the plurality of groups of first data signals to obtain a plurality of groups of second data signals, and each group of second data signals corresponds to the sub-pixels arranged in one row.
Each group of first data signals corresponds to the sub-pixels in a same color, so the data signals in each group of first data signals are similar to each other, and a swing frequency and a swing amplitude of the data signal in each group of first data signals are greatly reduced. In this way, it is able to remarkably reduce the power consumption of the control module 10 when the control module 10 outputs each group of first data signals to the driving module 20, thereby to achieve a better power-saving effect.
The driving module 20 rearranges the plurality of groups of first data signals to obtain the plurality of groups of second data signals corresponding to the sub-pixels in each row. During the display, when the sub-pixels in each row are scanned, the driving module 20 writes the group of second data signals corresponding to the sub-pixels in each row into the sub-pixels in a corresponding row through the plurality of data lines, so as to achieve a normal display function of the display device.

Each group of first data signals corresponds to the sub-pixels in a same color, so the data signals in each group of first data signals are similar to each other, and a swing frequency and a swing amplitude of the data signal in each group of first data signals are greatly reduced. In this way, it is able to remarkably reduce the power consumption when each group of first data signals is outputted to the driving module 20, thereby to achieve a better power-saving effect.
In addition, each group of first data signals corresponds to the sub-pixels in a same color, so the data signals in each group of first data signals are similar to each other. In this way, it is able to facilitate the compression of the plurality of groups of first data signals through the data compression sub-module 103.

The data processing sub-module 203 is configured to process the plurality of groups of second data signals through a sub-pixel rendering algorithm so as to obtain the plurality of groups of second data signals corresponding to the sub-pixels in each row in an RGBG arrangement mode in
According to the display device in the embodiments of the present disclosure, the driving module 20 includes the data decompression sub-module 201, the data rearrangement sub-module 202 and the data processing sub-module 203, so as to transmit the plurality of first data signals to the plurality of data lines after compression, rearrangement and data processing. An object of the sub-pixel rendering algorithm is to enable the plurality of groups of second data signals to correspond to an actual arrangement mode of the sub-pixels in the display device, so as to write the data signals into the sub-pixels in each row in a better manner.

As shown in
According to the display device in the embodiments of the present disclosure, each first data line 41 is coupled to the first sub-pixels in a corresponding sub-pixel group, so that the sub-pixels coupled to the first data line 41 are the first sub-pixels in a same color. When the first data line 41 transmits the data signals to the sub-pixels and there is a small change in an image displayed by the display device, the data signal transmitted through the first data line 41 is maintained as a constant voltage for a long time period, so as to reduce a change frequency of the data signal transmitted through the first data line 41. When an image displayed by the display device is refreshed, voltage values of the desired data signals for the first sub-pixels are similar to each other, so a swing amplitude of the data signal transmitted through the first data line 41 is small, and there is a small change frequency of the data signal. In this regard, it is able to reduce the power consumption. In addition, the above arrangement mode of the first data lines 41 and the second data lines 42 is adapted to the conventional RGBG arrangement mode, without any need to change the arrangement mode of pixels.
As shown in
For example, the plurality of sub-pixels includes sub-pixels arranged in a plurality of rows in a second direction, and the sub-pixels in each row include sub-pixels arranged in a first direction. For example, the sub-pixels in each row include, but not limited to, first sub-pixels, third sub-pixels and second sub-pixels arranged alternately in sequence in the first direction.
As shown in
For example, the first connection portion 411 includes at least a portion extending in a third direction, and the third direction intersects both the first direction and the second direction.
For example, the plurality of first connection portions 411 is coupled to each other in an end-to-end manner, and the second connection portion 412 is coupled to the driving module 20.
As shown in
According to the display device in the embodiments of the present disclosure, each second data line 42 is coupled to the first sub-pixels in a corresponding sub-pixel group, so that the sub-pixels coupled to the second data line 42 are the first sub-pixels in a same color. When the second data line 42 transmits the data signals to the sub-pixels and there is a small change in an image displayed by the display device, the data signal transmitted through the second data line 42 is maintained as a constant voltage for a long time period, so as to reduce a change frequency of the data signal transmitted through the second data line 42. When an image displayed by the display device is refreshed, voltage values of the desired data signals for the second sub-pixels are similar to each other, so a swing amplitude of the data signal transmitted through the second data line 42 is small, and there is a small change frequency of the data signal. In this regard, it is able to reduce the power consumption.
As shown in
As shown in
For example, the third connection portion 421 includes at least a portion
extending in the third direction.
For example, the plurality of third connection portions 421 is coupled to each other in an end-to-end manner, and the fourth connection portion 422 is coupled to the driving module 20.
For example, an orthogonal projection of the third connection portion 421 onto a base substrate of the display device partially overlaps with an orthogonal projection of the first connection portion 411 onto the base substrate. For example, the first connection portion 411 is arranged at a layer different from the third connection portion 421.
According to the display device in the embodiments of the present disclosure, when the first data lines 41 and the second data lines 42 are arranged as mentioned hereinabove, it is able to reduce the power consumption of the display device without any additional data lines.
For example, a length of the first data line 41 is the same as a length of the second data line 42, so as to reduce the occurrence of a signal delay for the sub-pixels.
As shown in
For example, the fourth data line 44 includes at least a portion extending in the second direction, and the fifth data line 45 includes at least a portion extending in the second direction.
For example, the fourth data line 44 is arranged at a same layer and made of a same material as the fifth data line 45.
According to the display device in the embodiments of the present disclosure, each fourth data line 44 is coupled to the first sub-pixels in the sub-pixels in a corresponding first column, and each fifth data line 45 is coupled to the second sub-pixels in the sub-pixels in the corresponding first column, so that the sub-pixels coupled to the fourth data line 44 are the first sub-pixels in a same color, and the sub-pixels coupled to the fifth data line 45 are the second sub-pixels in a same color.
When the data signals are transmitted to the sub-pixels through the fourth data lines 44 and the fifth data lines 45 and there is a small change in an image displayed by the display device, the data signals transmitted through the fourth data line 44 and the fifth data line 45 are maintained as constant voltages for a long time period, so as to reduce a change frequency of the data signals transmitted through the fourth data line 44 and the fifth data line 45. When an image displayed by the display device is refreshed, voltage values of the desired data signals for the first sub-pixels are similar to each other and voltage values of the desired data signals for the second sub-pixels are similar to each other, so swing amplitudes of the data signals transmitted through the fourth data lines 44 and the fifth data lines 45 are small, and there is a small change frequency of the data signals. In this regard, it is able to reduce the power consumption.
Based on the above-mentioned arrangement mode, although the quantity of data lines is increased, a load of each data line, the swing amplitude and the frequency of the data line are reduced, so it is still able to reduce the power consumption.
As shown in
For example, the third data line 43 includes at least a portion extending in the second direction.
As shown in
For example, the length of the first data line 41 and the length of the second data line 42 are greater than a length of the third data line 43.
For example, the third data line 43, the first connection portion 411 and the third connection portion 421 are arranged at different layers. For example, the display device includes three data line layers, the first connection portion 411 is arranged at a first data line layer, the third connection portion 421 is arranged at a second data line layer, and the third data line 43 is arranged at a third data line layer.
In a possible embodiment of the present disclosure, the first connection portion 411 and/or the third connection portion 421 do not overlap with the other sub-pixels. For example, the first connection portion 411 and/or the third connection portion 421 do not overlap with an anode of the green (G) pixel, so as to reduce a parasitic capacitance generated by the data line.

When the data signals are transmitted to the sub-pixels through the sixth data line 46, the seventh data line 47 and the eighth data line 48 and there is a small change in an image displayed by the display device, the data signals transmitted through the sixth data line 46, the seventh data line 47 and the eighth data line 48 are maintained as constant voltages for a long time period, so as to reduce a change frequency of the data signals transmitted through the sixth data line 46, the seventh data line 47 and the eighth data line 48. When an image displayed by the display device is refreshed, voltage values of the desired data signals for the first sub-pixels are similar to each other, voltage values of the desired data signals for the second sub-pixels are similar to each other, and voltage values of the desired data signals for the third sub-pixels are similar to each other, so swing amplitudes of the data signals transmitted through the sixth data line 46, the seventh data line 47 and the eighth data line 48 are small, and there is a small change frequency of the data signals. In this regard, it is able to reduce the power consumption.
Based on the above-mentioned arrangement mode, although the quantity of data lines is increased, a load of each data line, the swing amplitude and the frequency of the data line are reduced, so it is still able to reduce the power consumption.

In this way, it is able to remarkably reduce the power consumption of the control module 10 when the control module 10 outputs each group of first data signals to the driving module 20, thereby to achieve a better power-saving effect.

Depending on different specific patterns, a single patterning process may include multiple exposing, development or etching processes, and the specific patterns in the layer structure may be continuous or discontinuous. These specific patterns may also be arranged at different levels or have different thicknesses.
In the embodiments of the present disclosure, the order of the steps is not limited to the serial numbers thereof. For a person skilled in the art, any change in the order of the steps shall also fall within the scope of the present disclosure if without any creative effort.
It should be further appreciated that, the above embodiments have been described in a progressive manner, and the same or similar contents in the embodiments have not been repeated, i.e., each embodiment has merely focused on the difference from the others. Especially, the method embodiments are substantially similar to the product embodiments, and thus have been described in a simple manner.
Unless otherwise defined, any technical or scientific term used herein shall have the common meaning understood by a person of ordinary skills. Such words as “first” and “second” used in the specification and claims are merely used to differentiate different components rather than to represent any order, number or importance. Similarly, such words as “one” or “one of” are merely used to represent the existence of at least one member, rather than to limit the number thereof. Such words as “include” or “including” intends to indicate that an element or object before the word contains an element or object or equivalents thereof listed after the word, without excluding any other element or object. Such words as “connect/connected to” or “couple/coupled to” may include electrical connection, direct or indirect, rather than to be limited to physical or mechanical connection. Such words as “on”, “under”, “left” and “right” are merely used to represent relative position relationship, and when an absolute position of the object is changed, the relative position relationship will be changed too.
It should be appreciated that, in the case that such an element as layer, film, region or substrate is arranged “on” or “under” another element, it may be directly arranged “on” or “under” the other element, or an intermediate element may be arranged therebetween.
In the above description, the features, structures, materials or characteristics may be combined in any embodiment or embodiments in an appropriate manner.
The above embodiments are for illustrative purposes only, but the present disclosure is not limited thereto. Obviously, a person skilled in the art may make further modifications and improvements without departing from the spirit of the present disclosure, and these modifications and improvements shall also fall within the scope of the present disclosure.
