Abstract

The invention relates to an AMOLED transparent display pixel structure, belonging to the technical field of display. The transparent display pixel structure comprises a plurality of pixels, each pixelcomprises three sub-pixels with different colors, and the light emitting area of each sub-pixel is provided with a transparent area. The transparent areas in the adjacent sub pixels in the pixel structure are located at different positions (the position of a top portion, the position of a middle portion and the position of a bottom portion) of the sub pixels. According to the AMOLED transparent display pixel structure, the transparent areas are arranged at different positions in the sub-pixels, so that the problem of displaying transverse stripes is effectively solved while the light transmittance is ensured.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an AMOLED transparent display pixel structure. Background technique [0002] Transparent display refers to a display that can form a transparent display state so that observers can see the image behind the screen. It is a brand-new display technology that can be applied to display devices such as mobile phones, notebook computers, display windows, and billboards. Active matrix organic light-emitting diodes (AMOLED) have the advantages of self-luminescence, high luminous efficiency, low operating voltage, thin panel thickness, flexible panel and simple manufacturing process, etc., and are often used to make transparent displays. The principle of AMOLED self-luminescence is: the indium tin oxide semiconductor (ITO) electrode and the metal electrode fabricated on the backplane are respectively used as the anode and cathode of the device, and the organic semiconductor material and t...
