Problems solved by technology

[0003] Nowadays, the use of fine mask (FMM) technology is difficult to meet the high-definition pixel requirements of silicon-based OLEDs, so the colorization scheme of silicon-based OLEDs can only use white OLED + color filter (CF) technical solutions.
However, silicon-based OLED devices using this solution are limited by the relatively low efficiency of white OLEDs and the 70% light efficiency loss of CF. The brightness of silicon-based OLED products is greatly limited, and it is difficult to meet the requirements of head-mounted displays, especially AR head-mounted displays. Requirements for Microdisplay Devices

Abstract

The invention belongs to the technical field of microdisplay, in particular to a silicon-based OLED microdisplay device with high brightness and high color gamut. The silicon-based OLED microdisplay of the present invention does not need to prepare color filters, and can realize RGB and other color OLED emission through the adjustment of the corresponding pixel layer. Under the condition of ensuring the high PPI of the silicon-based OLED microdisplay, the existing The brightness and efficiency of the silicon-based OLED produced in the technology can reduce the power consumption of the silicon-based OLED display device under the same brightness condition, and at the same time can greatly improve the poor color gamut of the white OLED plus color filter scheme in the prior art. question.

Description

technical field [0001] The invention belongs to the field of micro-display technology, in particular to a silicon-based OLED micro-display device. Background technique [0002] Silicon-based OLED (Organic Light Emitting Display) is known as the dark horse of next-generation display technology. It is different from conventional AMOLED devices that use amorphous silicon, microcrystalline silicon or low-temperature polycrystalline silicon thin-film transistors as backplanes. It is based on single-crystal silicon As an active organic light-emitting diode display device made of an active driving backplane, the pixel size is 1 / 10 of the traditional display device, and the fineness is much higher than that of the traditional device. It has high resolution, high integration, low power consumption, and small size. Small, light weight and many other advantages. Silicon-based OLED microdisplays have been widely used in military markets such as machine-mounted helmets, gun sights, and ...
