Problems solved by technology

However, it is difficult for existing OLEDs to meet the high-resolution and high-brightness requirements of electronic devices for display screens, because when the resolution of OLEDs reaches more than 300PPI (pixels per inch), the pixel arrangement structure of traditional RGB stripes is difficult to achieve. Evaporate organic light-emitting materials with a metal mask, and due to the low aperture ratio, the current density injected into the OLED is high, and it is necessary to choose a compromise between brightness and life
In order to improve this problem in the industry, although some manufacturers have proposed a more efficient pixel arrangement called "PenTileRGB", but this arrangement has problems such as increased image crosstalk, obvious moiré effect, and deterioration of oblique line aliasing.

Abstract

The invention provides an OLED (Organic Light Emitting Diode) pixel arrangement structure. The OLED pixel arrangement structure comprises an R sub-pixel group, a G sub-pixel group and a B sub-pixel group; the R sub-pixel group is formed by plural R sub-pixels; the G sub-pixel group is formed by plural G sub-pixels; the B sub-pixel group is formed by plural B sub-pixels; the R sub-pixel group, the G sub-pixel group and the B sub-pixel group are arranged separately to enable every adjacent R sub-pixel, G sub-pixel and B sub-pixel which are arranged in the R sub-pixel group, the G sub-pixel group and the B sub-pixel group respectively to form a pixel. According to the OLED pixel arrangement structure, the same color of sub-pixels are gathered into a sub-pixel unit and accordingly the opening rate of a metal mask template can be improved under the same resolution of an OLED display screen in comparison with the single sub-pixel in the prior art, the problem that the manufacture of the metal mask template is difficult is solved, or every sub-pixel in one sub-pixel unit can be small under the same opening rate of the metal mask template so as to well improve the resolution of the OLED display screen.

Description

technical field [0001] The invention relates to OLED display technology, in particular to an OLED pixel arrangement structure. 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 and ma...
