Wide-color-gamut high-brightness evenness OLED pixel array

Abstract

The invention discloses a wide-color-gamut high-brightness evenness OLED pixel array. Each pixel of an OLED component is composed of a sub-pixel R, a sub-pixel G, a sub-pixel B and a sub-pixel Y, wherein the four sub-pixels are not arranged in order. A driving IC is used for driving all the sub-pixels to control the chromaticity output of pixels. A white light-emitting pixel W is distributed among every four sub-pixels which are the sub-pixel R, the sub-pixel G, the sub-pixel B and the sub-pixel Y. The white light-emitting pixels W are driven and controlled by the driving IC in the image display process of the component. Each pixel is of an RGBY+W star class or annular pixel array structure. The RGBY+W star class or annular pixel array structure is adopted, the display color gamut of the OLED component can be effectively increased, besides, brightness compensation can be performed on bright unevenness which is caused by the limit of the technology in the manufacturing process of the OLED component, and the problem that due to the limit of the technology, the brightness unevenness is generated is solved.

Description

technical field [0001] The invention belongs to the field of OLED display technology, in particular to an OLED pixel array with wide color gamut and high brightness uniformity. Background technique [0002] OLED (Organic Light Emitting Diode) is an organic electroluminescent technology. Its light-emitting principle is: sandwich an organic light-emitting material between a transparent anode and a metal reflective cathode, and apply a voltage to the organic film, under the action of an external electric field , electrons and holes are respectively injected from the cathode and anode into the organic functional film, and the injected electrons and holes migrate from the electron transport layer and the hole transport layer to the light-emitting layer respectively, and recombine in the light-emitting layer to form excitons, and the exciton radiative transition Photons are generated to complete the light-emitting process, which can be used as both display technology and lighting ...
