Description

Display device and electronic apparatus
Technical Field

Background
As shown in fig. 1, as the viewing angle between the viewer and the display increases, the color shift perceived by the viewer tends to be more severe from slight.
At the same time, there is also a large difference between the front-view luminance and the side-view luminance perceived by the viewer, and as shown in fig. 2, the ordinate represents the luminance percentage, the abscissa represents the gray scale, the curve S1 represents the luminance change in the side view, and the curve S2 represents the luminance change in the front view.
Based on the above-described problems, the related art improves the viewing angle by using a design technique of 8 domains (domains), but the design technique may cause a decrease in transmittance, which in turn may cause a deterioration in power consumption.
In addition, the related art also has a similar effect achieved by a spatial compensation technique in the timing controller (Tcon). However, this spatial compensation technique causes a decrease in picture resolution and a poor picture quality. Specifically, as shown in fig. 3, the first to fifth columns from left to right are respectively 0 gray scale, 64 gray scale, 128 gray scale, 192 gray scale and 255 gray scale, and the gray scale distribution of the corresponding sub-pixels is that the gray scale distribution of each sub-pixel remains the same, for example, the gray scale of each sub-pixel is 128 gray scale when the spatial compensation is not performed. After the spatial compensation technique is adopted, four sub-pixels distributed in an array are used as a minimum repeating unit, in the minimum repeating unit, the sub-pixels in the upper row keep higher same gray level, the sub-pixels in the lower row keep lower same gray level, so that liquid crystals have different deflection angles, the gray level in the upper row is overlapped with the gray level in the lower row and is consistent with the target gray level after being averaged, and the spatial compensation technique can improve the visual angle, but also reduces half of the picture resolution. The visual effect of the spatial compensation technique is shown in fig. 4, the right graph in fig. 4 is the original graph, and the left graph in fig. 4 is the display effect after the spatial compensation technique, and it can be obviously seen that compared with the right graph, the left graph has rough picture and larger granular feel.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In view of the above-mentioned problem that the viewing angle and the transmittance are difficult to be improved simultaneously, the present embodiment provides a display device, referring to fig. 5 to 8, as shown in fig. 5, the display device includes a display panel 100 and a timing controller 200, the display panel 100 includes at least one sub-pixel array 110, and each sub-pixel array 110 includes a plurality of sub-pixels 111; the timing controller 200 is connected with the display panel 100; the timing controller 200 includes at least one set of spatial compensation tables 210, at least one set of temporal compensation tables 220, and a temporal control module 230, wherein the spatial compensation tables 210 are used for configuring different gray scales to the plurality of sub-pixels 111 in each sub-pixel array 110 in one frame; the time compensation table 220 is used for configuring a plurality of gray scales to at least one sub-pixel array 110 in one frame; the time control module 230 is used for controlling the working time of each gray level in the time compensation table 220.
It can be appreciated that in the display device provided in this embodiment, by executing at least one set of the spatial compensation tables 210 by the timing controller 200 to spatially compensate, different gray scales can be configured to the plurality of sub-pixels 111 in each sub-pixel array 110 in one frame, and the viewer can see the display effect of the middle gray scale, so that the spatial compensation can reduce the resolution degradation compared to the sacrifice of the brightness of one row of sub-pixels 111 in the related art; the time control module 230 controls the working time of the corresponding gray scale in the time compensation table 220 to compensate in time, so that a viewer can see the display effect of the middle gray scale, and in combination with the space compensation, not only can the graininess and the flicker feel be reduced, but also the transmittance and the brightness difference between the front side views, namely the viewing angle, can be improved compared with 8 domains.
In one embodiment, as shown in fig. 5 and 6, each sub-pixel array 110 includes an upper left sub-pixel 111, an upper right sub-pixel 111, a lower left sub-pixel 111 and a lower right sub-pixel distributed in an array, and in the same frame, the spatial compensation table 210 sequentially configures a first gray scale, a second gray scale, a third gray scale and a fourth gray scale to the upper left sub-pixel 111, the upper right sub-pixel 111, the lower left sub-pixel 111 and the lower right sub-pixel respectively; the first gray scale, the second gray scale, the third gray scale and the fourth gray scale are different from each other.
It should be noted that, the number of the sub-pixels 111 distributed in the array included in each sub-pixel array 110 is not limited to four in the present embodiment, and may be an even number of six, eight, ten, or the like. Compared with the case that the same row of the sub-pixels 111 in the same sub-pixel array 110 is assigned the same gray level in fig. 3, which results in sacrificing the brightness of one row of the sub-pixels 111, the brightness of one row of the sub-pixels 111 is not lost in the same sub-pixel array 110, and the human eye recognizes the average gray level of one sub-pixel array 110 due to the spatial combination of the different gray levels of the same sub-pixel array 110, so that a plurality of different intermediate gray levels, for example, 1/4 gray levels, 2/4 gray levels, 3/4 gray levels, and the like can be further combined between the four different gray levels.
In one embodiment, the first gray scale, the second gray scale, the third gray scale, and the fourth gray scale decrease in sequence.
It should be noted that the first gray level, the second gray level, the third gray level, and the fourth gray level may also be sequentially increased, that is, the sizes of the first gray level, the second gray level, the third gray level, and the fourth gray level may be sequentially changed. The two gray scale arrangement sequences can be used as a preferred embodiment, so that the arrangement of the gray scales in the sub-pixel array 110 is gradually changed, which is beneficial to slowing down or avoiding the graininess.
Specifically, the working principle of the spatial compensation table 210 provided in the present application is shown in fig. 6, where the first row in fig. 6 is a schematic diagram in which each sub-pixel 111 is assigned the same gray level before spatial compensation is performed. The second row in fig. 6 is a schematic diagram after spatial compensation as shown in fig. 3. The third row in fig. 6 is a schematic diagram after executing the spatial compensation table 210 provided herein. In fig. 6, the five columns from left to right are respectively assigned values of the gray scale of each sub-pixel 111 under the gray scale of 0, the gray scale of 64, the gray scale of 128, the gray scale of 192 and the gray scale of 255, for example, taking the gray scale of 64 as an example, the gray scale of each sub-pixel 111 shown in the first row is 64; each sub-pixel 111 in the upper row of the sub-pixel array 110 in the second row has one gray level, and each sub-pixel 111 in the lower row of the sub-pixel array 110 in the second row has another gray level; and each of the sub-pixels 111 in the same sub-pixel array 110 in the third row has a different gray scale from each other, wherein the gray scale average value of each of the sub-pixels 111 in the same sub-pixel array 110 is 64 gray scales.
In one embodiment, as shown in fig. 5 and 7, the time control module 230 controls the time compensation table 220 to configure a gray scale to at least one sub-pixel array 110 in a first period of a frame; the time control module 230 controls the time compensation table 220 to configure another gray scale to the at least one sub-pixel array 110 in a second period of time of a frame; wherein the first time period is different from the second time period.
It should be noted that, in this embodiment, a frame may include a plurality of time periods that do not overlap in time, for example, a first time period, a second time period, a third time period, and so on, each time period may correspond to a gray scale, and the more the time periods are divided, the better the time compensation effect provided in this application is. Wherein the first time period may be earlier or later than the second time period.
Different gray scales are configured in different time periods, so that the display brightness of different time periods in one frame can be changed, the display brightness of one frame is further adjusted, and the fusion of brightness is realized by utilizing the visual inertia of human eyes, namely, the brightness feeling of the human eyes can not disappear immediately along with the disappearance of the brightness of an object, so that the compensation of the application in time is realized.
Specifically, the working principle of the time compensation table 220 provided in the present application is shown in fig. 7, where the first column, the second column, the third column and the fourth column from left to right are the first Frame (1 st), the second Frame (2 nd), the third Frame (3 rd) and the fourth Frame (4 th) in four consecutive frames (frames), respectively. The first row is a frame corresponding to a gray level 255, the fifth row is a frame corresponding to a gray level 0, the two gray levels are two end points of the gray level 256, and there is no modulation space. In the second row, the first three frames of pictures can be configured to be 255 gray scales, and the fourth frame of pictures can be configured to be 0 gray scale, so that higher gray scales required by human eyes can be realized. In the third row, the first frame may be configured to be 255 gray scales, the second frame may be configured to be 0 gray scales, the third frame may be configured to be 255 gray scales, and the fourth frame may be configured to be 0 gray scales to realize lower gray scales required for human eyes to view. In the fourth row, the first frame may be configured to be 255 gray scales, the second frame may be configured to be 0 gray scales, the third frame may be configured to be 0 gray scales, and the fourth frame may be configured to be 0 gray scales to realize lower gray scales required for human eyes to view.
It should be noted that fig. 7 only shows the switching of gray levels between frames, and similarly, the time compensation table 220 in the present application can implement the switching of gray levels in different time periods within a frame in combination with the time control module 230, so as to implement more precise and fine time compensation.
In one embodiment, as shown in fig. 5 and 8, the timing controller 200 further includes at least one set of weight coefficient tables, each item of data in the weight coefficient tables includes a spatial compensation coefficient and a temporal compensation coefficient, the spatial compensation coefficient is used to scale each gray level in the spatial compensation table 210, and the temporal compensation coefficient is used to scale each gray level in the temporal compensation table 220; the timing controller 200 determines a gray scale range of the frame according to the received video signal, and invokes a corresponding spatial compensation coefficient and a corresponding temporal compensation coefficient according to the gray scale range of the frame.
It should be noted that, since the sensitivity of human eyes to different brightness is different, the embodiment can adjust the time compensation table 220 by the time compensation coefficient in the frame with low gray level to easily cause the flickering problem, and adjust the space compensation table 210 by the space compensation coefficient in the frame with high gray level to easily cause the graininess problem.
As shown in fig. 8, the curve S3 is a spatial compensation coefficient corresponding to different gray levels, and the curve S4 is a temporal compensation coefficient corresponding to different gray levels. It can be understood that different point values in the curves S3 and S4 correspond to different spatial compensation coefficients and temporal compensation coefficients, so as to form each item of data in the weight coefficient table, thereby obtaining the corresponding weight coefficient table.
In one embodiment, the gray scale range includes a low gray scale range, a medium gray scale range, and a high gray scale range; the spatial compensation coefficient is larger than the time compensation coefficient along with the increase of gray scale in the low gray scale range; the spatial compensation coefficient is equal to the time compensation coefficient along with the increase of gray scale in the middle gray scale range; the spatial compensation coefficient is smaller than the temporal compensation coefficient as the gray scale increases in the high gray scale range.
It should be noted that, the spatial compensation table 210, the time compensation table 220 and the time control module 230 can avoid the technical problems of transmittance decrease and resolution decrease perfectly, and improve the display effect of the brightness difference between the viewing angles, i.e. the front side views. On the basis of the embodiment, the magnitude relation between the space compensation coefficient and the time compensation coefficient is configured in different gray scale ranges, so that further optimization of flicker and granular feeling can be realized.
In one embodiment, the spatial compensation coefficient gradually decreases and the temporal compensation coefficient gradually increases with the increase of the gray scale in the low gray scale range and the high gray scale range; the spatial compensation coefficient and the time compensation coefficient are kept unchanged along with the increase of gray scale in the middle gray scale range.
It should be noted that, in the present embodiment, the trend of the spatial compensation coefficient and the temporal compensation coefficient in different gray scale ranges is the preferred embodiment obtained by long-term research and practice of the inventor, and the present embodiment can achieve a better display effect.
In one embodiment, in the low gray scale range, the spatial compensation coefficient ranges from 1 or more to 1.6 or less; in the middle gray scale range, the spatial compensation coefficient is equal to 1; in the high gray scale range, the range of the spatial compensation coefficient is greater than or equal to 0.35 and less than or equal to 1.
