Pixel structure, metal mask and oled display

Abstract

In accordance with one aspect of the disclosure, a pixel structure is provided including a plurality of pixel rows, each pixel row has first pixel units, second pixel units and third pixel units that are arranged sequentially in circles and have different colors, and each first pixel unit, each second pixel unit and each third pixel unit respectively consist of three first sub pixels having equal areas, three second sub pixels having equal areas and three third sub pixels having equal areas; the pixel units of the same color in odd and even rows among the plurality of pixel rows are staggered at a predetermined width; and one first sub pixel, one second sub pixel and one third sub pixel which are adjacent to one another in two adjacent pixel rows constitute a display pixel. The invention can increase the distance among the pixels of the same color, achieve a high resolution ratio, and enable the distance among apertures of a metal mask plate to reach the maximum, thereby improving the evaporation quality of the pixel structure.

Description

technical field [0001] The invention relates to a pixel arrangement method, in particular to a pixel structure for an organic light emitting diode (OLED) display screen, a metal mask plate and an OLED display screen. Background technique [0002] Compared with the traditional LCD display method, OLED display technology does not require a backlight. It has the characteristic of self-luminescence, and uses a very thin film layer of organic material and a glass substrate. When an electric current passes through it, the organic material will emit light. Therefore, OLED displays can significantly save power, can be made lighter and thinner, can withstand a wider range of temperature changes than LCD displays, and have a larger viewing angle. Among them, the light-emitting layer of the OLED screen is generally made of organic materials and organic light-emitting components are formed on the corresponding pixel positions on the array substrate through a high-definition metal mask ...

Problems solved by technology

However, the strip-shaped opening 31" needs to maintain its straightness and flatness, which is difficult to achieve on a fine metal mask

[0011] In summary, the existing metal masks have the above disadvantages, especially in the need to improve the resolution, the existing pixel arrangement and metal masks are difficult to achieve high resolution to ensure the quality of evaporation need
