Embodiment 1
[0077] In the embodiment of the present invention, such as Figure 12 As shown, the first sub-pixel is R, the second pixel is B, the third sub-pixel is G, the first pixel group is R-R-B, and the second pixel group is G-G-B, then the first pixel group is continuously and repeatedly arranged along the first direction , the second pixel group is continuously and repeatedly arranged along the first direction, and, in the embodiment of the present invention, the first direction is a direction with an included angle of 45 degrees with the Y axis;
[0078]In the pixel array area, each minimum arrangement unit includes two different types of sub-pixels, and in the pixel array area, the B color is arranged in a second direction, that is, the second direction is parallel to the Y-axis direction;
[0079] In the pixel array area, the distances between R, G, and B in the first pixel group and the second pixel are equal;
[0080] The shape of the three sub-pixels R, G, and B is a rectangl...
Embodiment 2
[0086] In order to better meet the high PPI requirement of OLED, in the embodiment of the present invention, as Figure 13 As shown, three sub-pixels are arranged in each minimum arrangement unit to improve the physical PPI of OLED;
[0087] Among them, the first sub-pixel is R, the second sub-pixel is B, the third sub-pixel is G, the first pixel group is R-R-B, and the second pixel group is G-G-B, then the first pixel group is continuously and repeatedly arranged along the first direction , the second pixel group is continuously and repeatedly arranged along the first direction;
[0088] In each smallest arrangement unit, B is located at the first intersection point of the smallest arrangement unit, R is located at any position on the line connecting the first intersection point of the smallest arrangement unit and the first vertex of the smallest arrangement unit, and B is located at the first intersection of the smallest arrangement unit Any position on the line between an...

Abstract
The present invention provides a pixel array, which relates to the field of organic light emitting diode display technology. The method includes: the pixel array includes a first pixel group and a second pixel group, and the first pixel group includes at least two first sub-pixels and a second pixel group arranged continuously. Two sub-pixels, the second pixel group includes at least two third sub-pixels and one second sub-pixel arranged continuously; the first pixel group and the second pixel group are repeatedly arranged in the first direction, and the line where the first pixel group is located is the same as The straight lines where the second pixel group is located are parallel and alternately and repeatedly arranged; the number of first sub-pixels, second sub-pixels and third sub-pixels included in at most four adjacent minimum arrangement units in the pixel array is the same. In the embodiment of the present invention, the above-mentioned pixel array effectively solves the problem in the prior art that it is difficult to make corresponding openings for the R and G colors when the OLED has a high PPI, and ensures the luminous efficiency of the three types of pixels.
Description
technical field [0001] The invention relates to the technical field of light emitting diode display, in particular to a pixel array. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) displays are famous for their thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, and high and low temperature resistance. It is recognized by the industry as the third generation of display technology after liquid crystal display (LCD). According to the driving method, OLED is divided into passive OLED (Passive Matrix OLED, PMOLED) and active OLED (Active Matrix OLED, AMOLED). PMOLED is also called passive matrix OLED, and AMOLED is also called active matrix OLED. PMOLED can only To produce small-sized, low-resolution display panels, AMOLED can realize large-sized, high-resolution panels because it integrates a thin-film transistor (TFT) and a capacitor in each pixel ...
