FIG. 1B is an embodiment of the display panel 14 described above. In this embodiment, the display panel 14 includes three columns of pixels, and each column of pixels includes three pixels as an example to illustrate the arrangement of pixels, but not For this reason, each pixel is electrically coupled to the data driver 12 and the gate driver 13. The display panel 14 of the embodiment includes a first pixel 141, a second pixel 142, and a third pixel 143 in each column of pixels. The first column of pixels is the first pixel 141 from left to right. a second pixel 142 and a third pixel 143. The second column of pixels from left to right is a third pixel 143, a first pixel 141, and a second pixel 142. The three columns of pixels from left to right are the second pixel 142, the third pixel 143, and the first pixel 141. The first pixel 141 includes a first sub-pixel 1411 and a second sub-pixel 1412. The second pixel includes a third sub-pixel 1421 and a fourth sub-pixel 1422. The third pixel includes a first pixel. The fifth sub-pixel 1431 and a sixth sub-pixel 1432, the second pixel 142 is adjacent to the first pixel 141, and the third pixel 143 is adjacent to the first pixel 141, in this embodiment, the third The sub-pixel 1421 is further adjacent to the first pixel 141, and the fifth sub-pixel 1431 is further adjacent to the first pixel 141, wherein the first sub-pixel 1411 is used to display a first color display data, and the second The sub-pixel 1412 is for displaying a second color display data, the third sub-pixel 1421 is for displaying a third color display data, and the fourth sub-pixel 1422 is for displaying the first color display data and the second color. One of the displayed materials, the fifth sub-pixel 1431 is for displaying the third color display data, and the sixth sub-pixel 1432 is for displaying one of the first color display data and the second color display data, wherein The first color display data, the second color display data, and the third color display data are RGB three originals Wherein one of each other and do not overlap.

The following is an example of the pixel in the second column of FIG. 1B, and cooperates with FIG. 1A. FIG. 2A illustrates the driving manner of the display panel 14. First, the control circuit 11 receives, by the outside, a first display material, a second display material, and a third display data corresponding to the first pixel 141, the second pixel 142, and the third pixel 143, and each of the display materials includes The first color display material, the second color display material, and the third color display material are described above (step 201). Then, the control circuit 11 converts the first color display data, the second color display data, and the third color display data into corresponding first color display data brightness, second color display data brightness, and third color display data brightness (step 202).

Next, the first color of the first pixel 14 is used as an example for description, but it is not limited thereto. The control circuit 11 first determines whether the brightness difference between the third color display material brightness corresponding to the first pixel 14 and the corresponding second pixel and the third color display material brightness of the third pixel is greater than a brightness threshold value (step 203). ). That is, if the third color of the first pixel 14 shows that the data brightness is L ₁₄₁ , the third color of the second pixel 142 shows that the data brightness is L ₁₄₂ , and the third color of the third pixel 143 shows that the data brightness is L ₁₄₃ When the luminance threshold is T _th , the control circuit 11 determines whether |L ₁₄₁ -L ₁₄₂ |>T _th or |L ₁₄₁ -L ₁₄₃ |>T _th , and in this embodiment, compares the first pixel 141 The second pixel 142 on both sides and the third color of the third pixel 143 indicate whether the brightness difference between the brightness of the data and the brightness of the third color of the first pixel 141 is greater than a brightness threshold, but in other implementations In the example, the brightness of the display data of the upper, lower, upper left, lower left, upper right, or lower right pixels of the first pixel 141 may also be compared, but not limited thereto.

If the second pixel 142 or the third pixel 143 is one of the third The brightness of the color display data is greater than the brightness of the third color display data corresponding to the first pixel 141, and the control circuit 11 assigns the brightness of the third color display data corresponding to the first pixel 141 to have a display material for displaying the third color. One of the second pixel 142 and the third pixel 143 of the sub-pixel is displayed (step 204). Otherwise, the control circuit will not perform luminance allocation, but directly performs step 205.

Since in this embodiment, each pixel cannot display all of it by itself. The RGB three primary colors, so the control circuit 11 needs to adjust the brightness of the first color display material of each pixel, the brightness of the second color display data, and the brightness of the third color display data according to the specific rendering matrix corresponding to the display panel 14, and obtain the update first. The color displays the brightness of the data, updates the brightness of the second color display material, and updates the brightness of the third color display data (step 205), so that the display panel 14 can still normally display the display data received by the control circuit 11.

Finally, the first color will be updated to display the brightness of the data, and the second color will be updated. Displaying the brightness of the color and updating the brightness of the third color display data into the updated first color display data of the grayscale value display data, updating the second color display data, and updating the third color display data (step 206), so that the display panel 14 can be The data is displayed in grayscale values for display.

Please refer to FIG. 2B. In step 204, the second picture is further determined. Whether the display brightness of the third sub-pixel 1421 for displaying the third color display data in the element 142 is greater than the display brightness of the fifth sub-pixel 1431 for displaying the third color display data in the third pixel 143 (step 2041) If the display brightness of the third sub-pixel 1421 is greater than the display brightness of the fifth sub-pixel 1431, the control circuit 11 assigns the third color display data brightness of the first pixel 141 to the third sub-pixel 1421 for performing. Display (step 2042a). Conversely, when the display brightness of the third sub-pixel 1421 is less than or equal to the display brightness of the fifth sub-pixel 1431, the control circuit 11 displays the data brightness of the third color of the first pixel 141. The fifth sub-pixel 1421 is assigned for display (step 2042b). In other embodiments, step 204 includes determining whether the display brightness of the third sub-pixel 1421 of the second pixel 142 for displaying the third color display data is greater than or equal to the third pixel 143 for displaying the third color. The brightness of the fifth sub-pixel 1431 of the color display data (step 2041), if the display brightness of the third sub-pixel 1421 is greater than or equal to the display brightness of the fifth sub-pixel 1431, the control circuit 11 will display the first pixel. The third color display material brightness of 141 is allocated to the third sub-pixel 1421 for display (step 2042a), and conversely, when the display brightness of the third sub-pixel 1421 is smaller than the display brightness of the fifth sub-pixel 1431, the control circuit 11 assigns the third color display material brightness of the first pixel 141 to the fifth sub-pixel 1421 for display (step 2042b).

Taking the display brightness of the third sub-pixel 1421 greater than the display brightness of the fifth sub-pixel 1431 as an example, the control circuit 11 then determines the third color display data brightness of the first pixel 141 plus the third sub-pixel 1421 originally required. One of the displayed display brightnesses is added to the brightness value whether it is less than or equal to a brightness maximum value, and the brightness maximum value is the maximum brightness value that can be displayed for each sub-pixel, that is, if the third color of the first pixel 141 is displayed. The brightness is L ₁₄₁ , the display brightness of the third sub-pixel 1421 is L ₁₄₂₁ , the maximum brightness is L _max , and the added brightness value is L ₁₄₁ + L ₁₄₂₁ = L _add , and the control circuit 11 determines whether L _add L _max (step 2043).

If so, the display brightness of the third sub-pixel 1421 is updated to the added brightness value, and the control circuit 11 updates the brightness of the third color display material corresponding to the first pixel to zero brightness (step 2043a). If not, the display brightness of the third sub-pixel 1421 is updated to the brightness maximum value, and the control circuit 11 updates the brightness of the third color display data corresponding to the first pixel 141 to the brightness of the added brightness value minus the maximum brightness value. . That is, the brightness of the third color display data corresponding to the first pixel 141 is updated to the brightness of L _add -L _max (step 2043b), and step 205 is continued (step 2044), and the third pixel corresponding to the first pixel 141 The color display data brightness is not zero brightness, so the third color display material brightness corresponding to the first pixel 141 can be displayed by the specific rendering matrix of step 205, and assigned to other pixels displaying the third color display data.

In step 2043, if the display brightness of the third sub-pixel 1421 is less than or equal to the display brightness of the fifth sub-pixel 1431, the control circuit 11 determines the third color of the first pixel 141 to display the brightness of the data plus the fifth sub-picture. Whether the summed brightness value of the display brightness originally required to be displayed is less than or equal to the above-mentioned brightness maximum value, that is, if the third color of the first pixel 141 indicates that the data brightness is L ₁₄₁ , the display of the fifth sub-pixel 1431 The brightness is L ₁₄₃₁ , the maximum brightness is L _max , and the added brightness value is L ₁₄₁ + L ₁₄₃₁ = L _add , and the control circuit 11 determines whether L _add L _max .

If so, the display brightness of the fifth sub-pixel 1431 is updated to the added brightness value, and the control circuit 11 updates the brightness of the third color display material corresponding to the first pixel to zero brightness (step 2043a). If not, the display brightness of the fifth sub-pixel 1431 is updated to the brightness maximum value, and the control circuit 11 updates the brightness of the third color display data corresponding to the first pixel 141 to the added brightness value minus the brightness maximum value. . That is, the brightness of the third color display data corresponding to the first pixel 141 is updated to the brightness of L _add -L _max (step 2043b), and step 205 is continued (step 2044), and the third pixel corresponding to the first pixel 141 The color display data brightness is not zero brightness, so the third color display material brightness corresponding to the first pixel 141 can be displayed by the specific rendering matrix of step 205, and assigned to other pixels displaying the third color display data.

According to the above content, and taking the brightness of the data displayed in the third color as an example, in the case where the brightness of the data of the third color of the first pixel 141 needs to be allocated, the present invention can further extract the following features: when the second pixel 142 original third color display data brightness is greater than the third pixel 143 When the second pixel of the second pixel 142 shows that the brightness of the data is less than the third pixel 143 Wherein, the SL ₁₄₂ is the third color of the first pixel 141, the second pixel 142 is displayed after the brightness is completed, and the third color is displayed, and the SL ₁₄₃ is the third color of the first pixel 141. The third pixel 143 after the distribution displays the brightness of the data, the BL ₁₄₁ is the brightness of the third color corresponding to the first pixel 141 and has not been allocated, and the BL ₁₄₂ is corresponding to the second pixel 142 and has not yet been allocated. The third color displays the brightness of the data, and BL ₁₄₃ is the brightness of the third color corresponding to the third pixel 143 and has not been allocated.

The display panel driving method of the present invention will be described below in conjunction with data. First, please refer to FIG. 3A. FIG. 3A is a schematic diagram of the luminance change of the pixel directly performing the rendering matrix operation. First, in FIG. 3A, the A area on the left-hand side is the first pixel 141, the second pixel 142, and the third pixel. 143 displays the brightness of the material in the original third color that has not been subjected to any brightness distribution, that is, the third color of the first pixel 141 shows a brightness of 4095, and the third color of the second pixel 142 shows a brightness of 3750. The third color of the three pixels 143 shows that the brightness of the data is 2000, and after the rendering matrix operation, the brightness of the third color display material of each pixel is converted into the B area of the right hand side, that is, the first pixel 141 The third color indicates that the brightness of the material changes to 0 due to the rendering matrix, and the third color of the second pixel 142 indicates that the brightness of the material is changed to 3865, the third color of the third pixel 143 indicates that the brightness of the data is changed to 2698 due to the rendering matrix, and the first pixel 141 cannot display the third color display data by itself, so the third color of the first pixel 141 displays the brightness of the data. The second pixel 142 and the third pixel 143, which can display the brightness of the third color display material, are allocated by the rendering matrix, but are not limited thereto.

Referring to FIG. 3B, FIG. 3B is a schematic diagram of the brightness change of the driving method of the present invention. First, the A area on the left-hand side of FIG. 3B is the same as FIG. 3A, and is the first pixel 141, the second pixel 142, and the third pixel. 143 displays the brightness of the material in the original third color that has not been subjected to any brightness distribution. Next, the A ₁ region in the middle of FIG. 3B will be described with reference to FIGS. 2A and 2B. First, after receiving the brightness of the third color display data of the first pixel 141, the second pixel 142, and the third pixel 143, the control circuit 11 determines that the third color of the first pixel 141 displays the brightness of the data and the second picture. The third color of the prime 142 and the third pixel 143 indicates whether the brightness difference of the brightness of the data is greater than the brightness threshold value, that is, whether there is a |4095-3750|>brightness threshold value or a |4095-2000|>brightness threshold value (Step 203), if one of the luminance differences is greater than the luminance threshold, then step 204 is performed. In step 2041, the display brightness levels of the third sub-pixel 1421 and the fifth sub-pixel 1431 for displaying the brightness of the third display material in the second pixel 142 and the third pixel 143 are determined, as shown in the left hand side of FIG. 3B. In the A area, the third color of the second pixel 142 shows that the data brightness 3750 is greater than the third color display data brightness 2000 of the third pixel 143, so the control circuit 11 displays the data in the third color of the first pixel 141. The brightness 4095 is allocated to the second pixel 142 (step 2042a), and it is determined whether the third color display material brightness of the first pixel 141 plus the third color display material brightness of the second pixel 142 is less than or equal to the brightness maximum value ( Step 2043). In this embodiment, the maximum brightness value is 4095, and the added brightness value of the brightness of the third color of the first pixel 141 plus the brightness of the third color of the second pixel 142 is 4095+3750= 7845, which is greater than the maximum value of the brightness, so step 2043b is performed to update the brightness of the third color display data of the second pixel 142 to the maximum value of the brightness, and the third color of the first pixel 141 displays the brightness of the data as the added brightness value. to the maximum brightness, i.e. 7845-4095 = 3750, the first pixel 141, a second 142 and a third color pixel a third pixel 143 of the display data to change the luminance of the luminance A ₁ is shown in an intermediate 3B, the After the rendering matrix operation, the luminance changes of the first pixel 141, the second pixel 142, and the third pixel 143 are as shown in the B region on the right-hand side of FIG. 3B. Comparing FIG. 3A with the B region of FIG. 3B, it is apparent that the second pixel 142 showing higher brightness in FIG. 3A shows higher brightness in FIG. 3B and lower brightness in FIG. 3A. The three pixels 143 show lower brightness in FIG. 3B, that is to say, through the driving method of the present invention, higher brightness contrast between pixels can be achieved, and the sharpness of the display picture is effectively improved.

Since the display panel of the present invention and the driving method thereof are corresponding When the third color of the first pixel indicates that the brightness of the data is greater than the brightness of the brightness of the second color or the third color of the third pixel, the third color display data corresponding to the first pixel is allocated to the second color. A pixel with a higher third color display material brightness in the pixel or the third pixel is displayed, compared to the sub-pixel rendering technique that only uses the rendering matrix operation, without adjusting the direction and coefficient of the rendering matrix, The pixel that originally has the higher brightness of the third color display material will display the brightness of the third color display material with higher brightness, and the pixel with the lower brightness of the third color display material will display the lower brightness. The three colors display the brightness of the data, so that the pixels can have higher brightness contrast when displaying the third color display data, and the effect of sharpening the display image is achieved.
