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% loss of light efficiency of CF. Requirements for Microdisplay Devices

Abstract

The invention belongs to the technical field of micro display, and particularly relates to a high-brightness and high-color-gamut silicon-based OLED micro display device. According to the silicon-based OLED micro display, a color filter does not need to be prepared, emission of RGB and other OLEDs of various colors can be achieved through adjustment of the corresponding pixel layers, the brightness and efficiency of a silicon-based OLED manufactured in the prior art can be greatly improved under the condition that it is guaranteed that the silicon-based OLED micro display is high in PPI, powerconsumption of the silicon-based OLED display device is reduced under the same brightness condition, and meanwhile, the problem of poor color gamut in a scheme including white light OLEDs and color filters in the prior art can be greatly improved.

Description

technical field [0001] The invention belongs to the field of micro-display technology, in particular to a silicon-based OLED micro-display device with high brightness and high color gamut. 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...
