Abstract

The invention relates to the technical field of semiconductor photoelectrons, in particular to a full-color high-resolution micro-display chip based on gallium nitride LEDs and the quantum dot technology.Cadmium selenide (CdSe) quantum dots (QD) of different scales are stimulated by light emitting of the gallium nitride LEDs to generate red, green and blue three radical colors respectively.The chip is composed of the red micron-grade LED capable of independently emitting light, the green micron-grade LED capable of independently emitting light and the blue micron-grade LED capable of independently emitting light.Each stimulated quantum dot is composed of n-Gan and p-Gan, wherein an inverted GaN-based LED is adopted for a Gan-based blue light chip of the stimulated quantum dot, electrodes of the p-GaN are transferred to another substrate through a bonding method, and a drive circuit of pixels is formed on the substrate.The scheme of generating a red, green and blue full-color micro displayer by stimulating the CdSe quantum dots through the GaN blue light chip is adopted, and therefore a better color gamut cover rate, higher color control accuracy and higher red, green and blue color purity are achieved.The advantages of the simple process and low cost are achieved.

Description

technical field [0001] The invention relates to the technical field of semiconductor optoelectronics, in particular to a full-color high-resolution micro-display chip based on gallium nitride LED and quantum dot technology. Background technique [0002] Wearable technology: With the development of Internet +, the rise of the Internet of Things, the development of virtual display (VR) and augmented reality (AR) technologies, wearable electronic products have begun to enter people's production and life. The most representative is Google's "Google Glass". The light-emitting chips used in such glasses have developed from LCD and OLED to array light-emitting diodes (Micro-array-LED). [0003] Micro-array-LED technology refers to the whole array of high-density micro-sized LEDs integrated on a chip. Like an LED display, each pixel can be addressed and individually driven to light up. It can be regarded as a reduced version of an outdoor LED display. The pixel distance is reduced...
