Problems solved by technology

[0004] Due to the lower limit of the opening area of ​​the mask, and in order to avoid the influence of tolerance in the manufacturing process, it is necessary to reserve enough gaps between the openings of adjacent pixels, so that the pixel density cannot be greatly increased.
Moreover, sub-pixels of different ...

Abstract

A pixel array and a manufacturing method thereof, and an organic light emitting diode array substrate are disclosed. The pixel array comprises a plurality of pixels. Each pixel comprises four sub-pixels. Sizes of the four sub-pixels are the same and shapes of the four sub-pixels are an isosceles trapezoid. The four sub-pixels are arranged in a shape of a half of a regular hexagon. A display screen possessing the above structure has high rotation symmetry. A high resolution ratio and a high homogeneous degree can be acquired from each direction of the display screen.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a pixel array, a manufacturing method thereof, and an organic light emitting diode array substrate. Background technique [0002] The light-emitting structure of an organic light-emitting diode (Organic Light-Emitting Diode, OLED) device includes a pair of electrodes and an organic light-emitting layer. When a DC voltage is applied, holes are injected into the organic light-emitting layer from the anode, and electrons are injected into the organic light-emitting layer from the cathode. When it reaches the ground state, it will emit photons and emit light. [0003] There are many methods for manufacturing OLED displays, among which OLED evaporation technology is to form organic light-emitting devices by evaporating organic light-emitting materials and passing through high-precision metal masks (FineMetalMask, FMM) at positions corresponding to pixels on the array substr...
