In this application, the area of the first sub-pixel is larger than that of the second sub-pixel, and the area of the first sub-pixel is larger than that of the third sub-pixel, that is, the area of the red sub-pixel 11 is larger than the area of the blue sub-pixel 12, and the red sub-pixel The area of the pixel 11 is larger than the area of the green sub-pixel 13. In the case where the same data voltage is applied to the red sub-pixel 11, the green sub-pixel 13, and the blue sub-pixel 12, the red sub-pixel 11 has a large area, which can improve the transmittance of red light, increase the long-wavelength light, and shorten the The reduction of light in the band is beneficial to reducing the color temperature of the display screen, making the display screen warmer to the human eye, consistent with the visual characteristics of Asians, improving the comfort of the human eye and the user experience.

In a pixel unit 10, the blue sub-pixel 12 and the green sub-pixel 13 are located in the same row, and the red sub-pixel 11 is located in another row. This arrangement is beneficial to the red sub-pixel 11, the blue sub-pixel 12, and the green sub-pixel 13. The distance between any two is close or even equal, which is conducive to the improvement of color mixing effect. Of course, the blue sub-pixel 12 and the green sub-pixel 13 may also be located in the same column, and the red sub-pixel 11 is located in another column. Such a setting is also conducive to any arbitrary relationship between the red, blue, and green sub-pixels 11, 12, and 13.

As shown in FIG. 3, in one pixel unit 10, the blue sub-pixel 12 and the green sub-pixel 13 are located below the red sub-pixel 11, and in a pixel unit 10 adjacent to the same row, the blue sub-pixels 12 and The green sub-pixel 13 is located above the red sub-pixel 11. In addition, the distances between the center points of any two sub-pixels of the blue sub-pixel 12, the green sub-pixel 13, and the red sub-pixel 11 are equal, and the three primary colors of the blue sub-pixel 12, the green sub-pixel 13, and the red sub-pixel 11 are respectively The distance between the center points of any two beams of colored light is also equal, which is beneficial to achieve a better color mixing effect.

As shown in FIG. 3 to FIG. 5, the pixel structure of the present application further includes a plurality of scan lines 14 sequentially arranged along a column direction and a plurality of data lines 15 arranged sequentially along a row direction and intersecting the plurality of scan lines 14. Each pixel unit 10 is connected to two scan lines 14 and two data lines 15, wherein the red sub-pixel 11 is connected to one scan line 14, and the blue sub-pixel 12 and the green sub-pixel 13 are connected to an adjacent scan line 14. The red sub-pixel 11 and the green sub-pixel 13 (or the blue sub-pixel 12) are connected to one data line 15, and the remaining blue sub-pixel 12 (or the green sub-pixel 13) is connected to an adjacent data line 15. Moreover, the scanning lines 15 are all located on the same side of the red sub-pixel 11 (or the green sub-pixel 13 and the blue sub-pixel 12) connected to it, as above (here refers to the upper side which can be determined by the observer based on FIG. 3 to FIG. 5) .

Taking the example shown in FIG. 3 as an example, in the first pixel unit 10 in the first row and the first column, the red sub-pixel 11 is connected to the G1-th scan line 14 and the D1-th data line 15 and the green sub-pixel 13 is connected To the G2 scanning line 14 and the D1 data line 15, the blue sub-pixel 12 is connected to the G2 scanning line 14 and the D2 data line 15; the second pixel unit in the first row and the second column In 10, the red sub-pixel 11 is connected to the G2 scan line 14 and the D3 data line 15, the green sub-pixel 13 is connected to the G1 scan line 14 and the D2 data line 15, and the blue sub-pixel 12 is connected to The G2 scan line 14 and the D3 data line 15.

Therefore, in the pixel structure of the present application, the two pixel units 10 are driven by two scanning lines 14 and three data lines 15 in total. In the pixel structure of the present application, the number of scanning lines 14 is doubled, and the data lines are doubled. The number of 15 is reduced by 1/2. Accordingly, the number of gate drivers is doubled, and the number of source drivers can be reduced by 1/2. Based on the cost of the source driver, it is lower than that of the gate driver. The applied pixel structure can also reduce costs.

In addition, the scanning lines 15 are all located on the same side of the red sub-pixel 11 (or the green sub-pixel 13 and the blue sub-pixel 12) connected to it, so that two adjacent scanning lines 15 are separated by the red sub-pixel 11 (or the green sub-pixel 13). Pixels 13 and blue sub-pixels 12) are spaced apart. In the same area of the display area, even if the number of scanning lines 15 doubles, the distance between two adjacent scanning lines 15 will not decrease. As a result, the distance between two adjacent scanning lines 15 is too small, which causes a capacitive effect, etc., which affects the performance of the scanning lines 15 or affects the manufacturing process of the scanning lines 15.

Specifically, an implementation solution is provided. The above-mentioned two adjacent pixel units 10 located in the same row share a data line 15. The green sub-pixels 13 of one pixel unit 10 and the adjacent pixel unit located in the same row may be used. The blue sub-pixels 12 of 10 are connected to the same data line 15. As shown in FIG. 3, in one pixel unit 10, the red sub-pixel 11 is connected to the 3M-2 data line 15 through the first thin-film transistor 16, and the green sub-pixel 13 is connected to the 3M-2 through the second thin-film transistor 17. Data lines 15, the blue sub-pixels 12 are connected to the 3M-1 data line 15 through the third thin-film transistor 18, are located in the same row and adjacent to the pixel unit 10, and the red sub-pixels 11 are connected through the first thin-film transistor 16 To the 3M data line 15, the green sub-pixel 13 is connected to the 3M-1 data line 15 through the second thin film transistor 17, and the blue sub-pixel 12 is connected to the 3M data line 15, M through the third thin film transistor 18. Is a positive integer.

Provide another implementation solution. The above-mentioned data line 15 located in the same row and adjacent two pixel units 10 may also be the green sub-pixel 13 of one pixel unit 10 and one pixel unit located in the same row and adjacent to each other. The green sub-pixels 13 of 10 are connected to the same data line 15 (the 3M-1 data line 15), as shown in FIG. 5, or the blue sub-pixels 12 of one pixel unit 10 are located in the same row and adjacent to each other. The blue sub-pixel 12 of the pixel unit 10 is connected to the same data line 15 (3M-1 data line 15), as shown in FIG. 4. That is, in two pixel units 10 located in the same row and adjacent to each other, in addition to the two red sub-pixels 11 being staggered, the two green sub-pixels 13 and the two blue sub-pixels 12 are also swapped respectively. Arranged, two green sub-pixels 13 are set between the two blue sub-pixels 12, and two blue sub-pixels 12 are set between the two green sub-pixels 13 to further improve the color mixing effect.

The red sub-pixel 11 includes The first sub-red pixel area 111 and the second sub-red pixel area 112, the sum of the areas of the first sub-red pixel area 111 and the second sub-red pixel area 112 is greater than the area of the blue sub-pixel 12, The area is equal to the area of the green sub-pixel 13, so that when the same data voltage is applied to all of the red sub-pixel 11, green sub-pixel 13, and blue sub-pixel 12, the transmittance of red light is increased, thereby reducing the display. The color temperature of the picture improves the comfort of the human eye and improves the user experience.

In the case where the same data voltage is applied to the red sub-pixel 11, the green sub-pixel 13, and the blue sub-pixel 12, the area of the red sub-pixel 11 is large, which can improve the transmittance of red light in the light of the backlight module, and has a long The increase of the light in the band and the decrease in the light in the short band are conducive to reducing the color temperature of the display screen, making the display screen seen by human eyes warmer, conforming to the visual characteristics of Asians, improving the comfort of the human eye and improving the user experience.

The above are only optional embodiments of the present application, and are not intended to limit the present application. For those skilled in the art, this application may have various modifications and changes. Any modification, equivalent replacement, or improvement made within the spirit and principle of this application shall be included in the scope of claims of this application.
