High-resolution OLED device and masking plate for manufacturing same

Abstract

A high-resolution OLED device comprises pixel units which are distributed into matrixes, each pixel unit comprises four pixels, and each pixel comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel; each red sub-pixel, the corresponding green sub-pixel and the corresponding blue sub-pixel are distributed in a shape like a Chinese character 'pin' in the corresponding pixel, and the red sub-pixels, the green sub-pixels and the blue sub-pixels of every two adjacent pixels in each pixel unit are symmetrical with respect to the public edge of the corresponding pixels. The high-resolution OLED device has the advantages that a manufacturing method is based on the proven FMM technique in the industry, but according to the special pixel distribution mode, a MASK evaporated with organic light-emitting materials is in a mesh shape, and each open hole corresponds to four sub-pixels. Under the situation of the same resolution, sizes of the open holes and sizes of connection bridges of the MASK are larger. A high-resolution OLED display screen can be manufactured on the basis the proven FMM technique in the industry; alternatively under the situation of the same resolution, the requirement for MASK processing and OLED display screen manufacturing processes can be reduced, and improvement on the product yield is facilitated.

Description

technical field [0001] The invention belongs to the field of organic light-emitting diode (OLED) display technology, and relates to a pixel arrangement structure of an OLED display panel, in particular to a high-resolution OLED device panel structure and a mask plate for manufacturing the OLED panel. Background technique [0002] Organic Light Emitting Diode (OLED) display is recognized by the industry as the second largest display after Liquid Crystal Display (LCD) due to its thinness, active light emission, fast response speed, wide viewing angle, rich colors and high brightness, low power consumption, high and low temperature resistance and many other advantages. The third-generation display technology can be widely used in terminal products such as smartphones, tablets, and TVs. However, personal mobile products such as smartphones on the market recently put forward higher and higher resolution requirements for display screens. The screen resolution (that is, pixel densi...
