Abstract

The invention discloses a pixel structure and an organic light-emitting display adopting the pixel structure. Wherein, the pixel structure includes a plurality of pixels, each pixel is composed of a plurality of sub-pixels, at least one pixel constitutes a pixel unit, vertically adjacent pixel units are arranged in a vertical mirror image, and / or horizontally adjacent pixel units are arranged in a Horizontal mirror arrangement. The present invention can increase the opening area of ​​the Mask during evaporation, reduce the difficulty of making the Mask process, and also reduce the evaporation process by using a reasonable pixel arrangement structure and sharing an opening on the Mask with the sub-pixels of adjacent pixels for evaporation. difficulty. There is no need to reserve a gap when evaporating the sub-pixels of the adjacent pixels of the Mask, and a real high PPI can be achieved while maintaining the requirements of the aperture ratio. In addition, the present invention can also increase the strength of the Mask, making it difficult to deform during use, improving product yield, extending the life of the Mask, and reducing costs.

Description

technical field

[0001] The present invention relates to the field of organic light-emitting display technology, in particular to a pixel structure and an organic light-emitting display using the pixel structure. Background technique

[0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) is an active light-emitting device. Compared with the traditional LCD (Liquid Crystal Display, liquid crystal display) display method, OLED display technology does not require a backlight and has the characteristic of self-luminescence. OLEDs use very thin layers of organic materials and glass substrates that emit light when an electric current passes through them. 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. OLED display is expected to become the next-generation flat panel display technology after LCD, and it is one of the mos...
