However, some disadvantages of the current display devices are still existed, such as: the conventional process still cannot make the pixel units of the same display panel have the same characteristics, so that the pixel units disposed at different positions or driven by different chips have different driving effects, and thus the driving current/voltage required by each pixel unit is different. However, the difference of the driving current/voltage required by the pixel units will cause the brightness unevenness among the pixel units during driving, thereby generating color shift, and the viewer will feel the above disadvantage more obviously under the display frame with low brightness.

In one embodiment, the data driver disables the first pixel from emitting light when the first set of displayed gray scale data is less than or equal to a first gray scale threshold, and disables the second pixel from emitting light when the second set of displayed gray scale data is less than or equal to a second gray scale threshold, the second gray scale threshold being greater than the first gray scale threshold.

The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
referring to fig. 1, fig. 1 is a schematic view of an embodiment of a Display device 100, and the Display device 100 is, for example, an Active Matrix Organic Light Emitting Display (AMOLED). The display device 100 includes a data driver 10, a gate driver 20, and a plurality of pixels 30, each pixel 30 including a plurality of sub-pixels 31. In this embodiment, each pixel 30 includes four sub-pixels 31, but not limited thereto. Each sub-pixel 31 is electrically coupled to the data driver 10 via the data line DL and the gate driver 20 via the gate line GL, a plurality of sub-pixels 31 in the same column are electrically coupled to the same data line DL, and a plurality of sub-pixels 31 in the same row are electrically coupled to the same gate line GL. Each sub-pixel 31 is configured to receive the gate driving signal transmitted by the gate driver 20 and is enabled by the gate driving signal, the enabled sub-pixel 31 receives the display data transmitted by the data driver 10, the display data is the driving current/voltage, and the display data corresponds to a gray scale data, and the gray scale data corresponds to a defined brightness, so that the enabled sub-pixel 31 can emit light according to the gray scale data.
An example of the arrangement of the pixels 30 is further described below. Referring to fig. 2A, fig. 2A is a schematic diagram of an arrangement embodiment of a pixel 30 according to the present invention. In the embodiment of the present invention, the pixel 30 includes four sub-pixels 31, each sub-pixel 31 corresponds to one of the three primary colors, so the pixel 30 includes a sub-pixel 31a corresponding to the red primary color R, a sub-pixel 31B and a sub-pixel 31c corresponding to the green primary color G, and a sub-pixel 31d corresponding to the blue primary color B. The pixel 30 is divided into a first pixel 30a and a second pixel 30b, the first pixel 30a is used for displaying a first set of gray scale data during a frame period, the second pixel is used for displaying a second set of gray scale data during a frame period, and the first pixel 30a and the second pixel 30b are adjacent to each other and form a pixel group 30G. In the embodiment shown in fig. 2A, the first pixels 30a and the second pixels 30b are adjacent to each other in a first direction X and a second direction Y, and are arranged in a staggered manner, and the first pixels 30a and the second pixels 30b adjacent to each other in the first direction X form a pixel group 30G, wherein the first direction X and the second direction Y are orthogonal to each other.
Referring to fig. 2B, fig. 2B is a schematic diagram of a second embodiment of the arrangement of pixels 30 according to the present invention. The difference between fig. 2B and fig. 2A is that, in the embodiment of fig. 2B, each pixel group 30G includes a first pixel 30a and two second pixels 30B in the first direction X and the second direction Y, and one of the second pixels 30B is disposed between the other second pixel 30B and the first pixel 30 a. In addition, each first pixel 30a is disposed between two second pixels 30b, and the two second pixels 30b are different pixel groups 30G. As shown in the first row of fig. 2B, taking the first pixel 30a and two consecutive second pixels 30B located at the right hand side of the first pixel 30a as an example of a pixel group 30G, in the same pixel group 30G, the left side of the second pixel 30B is configured with an adjacent first pixel 30a, and the right side of the second pixel 30B is configured with another second pixel 30B.
Referring to fig. 2C, fig. 2C is a third schematic diagram of an arrangement embodiment of a pixel 30 according to the present invention. The difference between fig. 2C and fig. 2A is that in the embodiment of fig. 2C, each pixel group 30G includes two first pixels 30a and one second pixel 30b in the first direction X and the second direction Y. In each pixel group 30G, one of the first pixels 30a is disposed between the other first pixel 30a and the second pixel 30 b. In addition, each second pixel 30b is disposed between two first pixels 30a, and the two first pixels 30a are different pixel groups 30G. As shown in the first column of fig. 2C, taking the second pixel 30b and two consecutive first pixels 30a located at the left of the second pixel 30b as an example of a pixel group 30G, in the same pixel group 30G, another adjacent first pixel 30a is disposed at the left of the first pixel 30a, and an adjacent second pixel 30b is disposed at the right of the first pixel 30 a.
Referring to fig. 2D, fig. 2D is a fourth schematic diagram of an arrangement embodiment of a pixel 30 according to the invention. Fig. 2D differs from fig. 2A in that, in the first direction X and the second direction Y, each pixel group 30G includes two first pixels 30a and two second pixels 30b, the two first pixels 30a are adjacent to each other, the two second pixels 30b are adjacent to each other, and one first pixel 30a and one second pixel 30b of the pixel group 30G are adjacent to each other. In the first direction X and the second direction Y, the first pixel 30a is disposed between another first pixel 30a and the second pixel 30b, and the second pixel 30a is disposed between the first pixel 30a and another second pixel 30b, taking a single first pixel 30a or two second pixels 30b as an example.
Therefore, in conjunction with the pixel 30 arrangement embodiments shown in fig. 2A-2D, the data driver 10 of the present invention is configured to determine whether to make the first pixel 30a and the second pixel 30b emit light according to the first gray scale data set, the second gray scale data set, the first gray scale threshold value and the second gray scale threshold value, wherein the second gray scale threshold value is greater than the first gray scale threshold value. Further, in the current display frame, when the first set of gray scale data for displaying is less than or equal to the first gray scale threshold, the data driver 10 makes the first pixel 30a emit no light, and when the second set of gray scale data for displaying is less than or equal to the second gray scale threshold, the data driver 10 makes the second pixel 30b emit no light. The non-light emission is, for example, a non-light emission signal transmitted by the data driver 10 to the electrically coupled first pixel 30a or the electrically coupled second pixel 30 b. That is, when the gray-scale values of the first and second sets of gray-scale data are both greater than the second gray-scale threshold value, the first and second pixels 30a and 30b emit light normally; when the gray scale values of the first and second sets of gray scale data are both less than the second gray scale threshold value and greater than the first gray scale threshold value, the first pixel 30a emits light normally, and the second pixel 30b does not emit light; when the gray-scale values of the first and second sets of gray-scale data are both less than the first gray-scale threshold value, the first pixel 30a and the second pixel 30b do not emit light.
In one embodiment, the second gray level threshold value may range from 10 to 20 gray levels, and the first gray level threshold value may range from 5 to 10 gray levels. For example, the first gray level threshold may be 5 gray levels, and the second gray level threshold may be 10 gray levels. In other embodiments, the first gray level threshold may be 7 gray levels, and the second gray level threshold may be 15 gray levels. In another embodiment, the first gray level threshold may be 10 gray levels, and the second gray level threshold may be 20 gray levels.
Referring to fig. 3A and 3B, fig. 3A and 3B are schematic diagrams of an embodiment of a pixel display. In the embodiment of fig. 3A, when the gray scale value of the first set of gray scale data is greater than the first gray scale threshold value and the gray scale value of the second set of gray scale data is greater than the second gray scale threshold value, the data driver 10 generates corresponding display data according to the first set of gray scale data and the second set of gray scale data, so that the first pixel 30a and the second pixel 30b display according to the corresponding display data. In the embodiment of fig. 3B, when the gray level of the first set of gray scale data is greater than the first gray level threshold, but the gray level of the second set of gray scale data is less than or equal to the second gray level threshold, that is, the second set of gray scale data has relatively low luminance, the data driver 10 generates corresponding display data according to the first set of gray scale data, and the data driver 10 generates a non-emitting signal according to the second set of gray scale data, so that the first pixel 30a performs normal display according to the corresponding display data, but the second pixel 30B does not perform light-emitting display because it receives the non-emitting signal, and the display effect is as shown in fig. 3B. In the embodiment of displaying a monochrome screen, the difference between the above-mentioned display modes is that when the pixels 30 need to be displayed according to the display data, only the sub-pixels 31 corresponding to the specific primary color of each pixel 30 emit light.
In the present invention, the display effect under low brightness, that is, the display effect when the second pixel 30b does not emit light, can be further adjusted by changing the ratio of the first pixel 30a and the second pixel 30b in the pixel group 30G. For example, in the embodiment of FIG. 3B, when the second pixel 30B does not emit light, the pixel group 30G displays half of the gray-scale data of the first set. Taking the first set of gray scale data as 10 gray scales as an example, the gray scale value displayed by the pixel group 30G is 5 gray scales at this time. Also taking fig. 2B as an example, the pixel group 30G includes a first pixel 30a and two second pixels 30B, and taking the first set of gray scale data as 9 gray scales as an example, when the second pixel 30B does not emit light, since two of the three pixels do not emit light at this time, for this pixel group 30G, the displayed gray scale value is one third of the first set of gray scale data, that is, 3 gray scales. Therefore, by doing so, the pixel group 30G can display a lower gray scale value than the first set of gray scale data as desired.
In addition, in different display frames, the first pixel 30a and the two second pixels 30B are displayed in an interlaced manner, which is further described with reference to fig. 4A, 4B and 4C. In this embodiment, each pixel group 30G includes a first pixel 30a and two second pixels 30 b. Fig. 4A shows an embodiment of a pixel 30 for displaying a first frame, fig. 4B shows an embodiment of a pixel for displaying a second frame, and fig. 4C shows an embodiment of a pixel for displaying a third frame, wherein the display times of the first frame, the second frame and the third frame are adjacent, and the display time of the first frame is earlier than that of the second frame, and the display time of the second frame is earlier than that of the third frame. Taking the first pixel 30a in the first row of the figure and indicated by the arrow in fig. 4A as an example, when displaying the second frame, the first pixel 30a is replaced by the adjacent second pixel 30 b. That is, the second pixel 30B, which is located at the left of the first pixel 30a in fig. 4A, receives the first set of gray scale data in fig. 4B to be converted into the first pixel 30a indicated by the arrow, and the first pixel 30a indicated by the arrow in fig. 4A receives the second set of gray scale data to be converted into the second pixel 30B. Then, when displaying the third frame, the first pixel 30a indicated by the arrow in FIG. 4B is converted into the second pixel 30B, and the second pixel 30B to the left of the first pixel 30a indicated by the arrow in FIG. 4B is converted into the first pixel 30a when displaying the third frame, as shown in FIG. 4C. And at the time of fig. 4C, all pixels 30 complete one pixel interleaving cycle. By this, it is effectively avoided that the specific pixel continues to be the first pixel 30a and has a relatively long display time, which leads to early aging, and thus the display lifetime of the display device 100 can be effectively prolonged.
In summary, the present invention also provides an embodiment of a driving method of a display device. Referring to FIG. 5, in step 501, each first pixel displays a respective first set of gray scale data and each second pixel displays a respective second set of gray scale data during the time of displaying the first frame. In step 502, the data driver 10 determines whether to make the corresponding first pixel 30a and the second pixel 30b according to the first display data and the second display data. Further, when the data driver 10 determines that the first set of gray scale data is less than or equal to the first gray scale threshold, the data driver 10 makes the first pixel 30a corresponding to the display not emit light, and when the data driver 10 determines that the second set of gray scale data is less than or equal to the second gray scale threshold, the data driver 10 makes the second pixel 30b corresponding to the display not emit light. In step 503, during the time of displaying the second frame, a part of the first pixels 30a is configured as the second pixels 30b, and a part of the second pixels 30b is configured as the first pixels 30a, i.e. the first pixels 30a and the second pixels 30b are alternately displayed.
In summary, the present invention uses the pixel arrangement and the setting of the gray level threshold to make some pixels not emit light when displaying a low-brightness display screen, so as to improve the brightness non-uniformity and color cast among the pixels. In addition, because the visual sensitivity of the viewer is low under low brightness, even if part of the pixels do not emit light, the experience effect of the viewer is not influenced.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.

each first pixel correspondingly displays a respective first group of gray scale data and each second pixel correspondingly displays a respective second group of gray scale data during the time of displaying a first frame; and
enabling the data driver to determine whether to enable the first pixel and the second pixel of the corresponding pixel group to emit light according to the first group of gray scale data and the second group of gray scale data;
wherein the step of enabling the data driver to determine whether to enable the corresponding first pixel and the second pixel to emit light according to the first set of gray scale data and the second set of gray scale data further comprises:
the data driver judges that the first group of gray scale data is less than or equal to a first gray scale threshold value, and the data driver enables the first pixel which is correspondingly displayed not to emit light; and
the data driver judges that the second group of gray scale data is less than or equal to a second gray scale threshold value, the data driver enables the second pixel which is correspondingly displayed not to emit light, and the second gray scale threshold value is greater than the first gray scale threshold value;
when the gray scale values of the first and second sets of gray scale data are both less than the second gray scale threshold value and greater than the first gray scale threshold value, the first pixel emits light and the second pixel adjacent to the first pixel does not emit light in the pixel group.
11. The driving method as claimed in claim 10, wherein the driving method comprises the steps of:
the data driver configures a portion of the first pixels as the second pixels and a portion of the second pixels as the first pixels at a time when a second frame is displayed, the first frame being adjacent to the second frame in time and the second frame being later than the first frame.
