Abstract

The invention provides a pixel structure and manufacture method thereof. The pixel structure comprises a substrate and pixel units on the substrate. Each of the pixel unit comprises a pixel circuit structural layer, a pixel definition layer, a pixel electrode, inorganic LED subpixel and a first OLED subpixel. The pixle circuit structural layer is formed on the surface of the substrate; the pixel definition layer is formed on the pixel circuit structural layer and has a first opening and a second opening; the pixel electrode is disposed in the first and second openings and electrically connected with the pixle circuit structural layer; the inorganic LED subpixel comprises an ahesion layer, a first semiconductor layer, a second semiconductor layer; the first OLED subpixel comprises a first transmission layer and a second transmission layer; beam emitted by the inorganic LED subpixel has a different color from that of beam emitted by the first OLED subpixel. The pixel structure can solve problems that blue light OLED subpixel has a relatively low luminous efficiency, and that red light OLED has a relatively low luminous efficiency after miniaturation.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure and a manufacturing method thereof. Background technique [0002] With the advancement of technology, the display has gradually changed from a relatively thick cathode ray tube (Cathode Ray Tube, CRT) display to a relatively flat and thin liquid crystal display (Liquid Crystal Display, LCD) or organic light emitting diode (Organic Light Emitting Diode, OLED) display. [0003] The liquid crystal display uses the backlight module to emit light, and generates light of different brightness and color through liquid crystal molecules and color filters respectively. Therefore, each pixel of the liquid crystal display cannot emit light by itself, and it is a passive light-emitting display. LCD monitors have a long lifespan and do not suffer from image burn-in. In addition, with the development of thin film transistor technology, each pixel in the liquid cryst...
