Embodiment 1

[0030] A silicon-based true RGB display device, such as figure 1 As shown, a light-emitting layer 4 is arranged between the hole transport layer 3 and the hole blocking layer 5 of the silicon-based real RGB display device;

[0031] The light emitting layer 4 includes a red light optical compensation layer 4-1, a common blue light emitting layer 4-2, a red light emitting layer 4-3 and a green light emitting layer 4-4;

[0032] Wherein, the red light optical compensation layer is disposed on the hole transport layer, but the upper surface of the hole transport layer is not completely covered by the red light optical compensation layer.

[0033] The red light optical compensation layer is set corresponding to the same width as the red light emitting layer, so as to realize optical compensation for the red light emitting layer and improve the color gamut of the silicon-based real RGB display device.

[0034] The red light emitting layer and the green light emitting layer are adj...

Embodiment 2

[0058] A silicon-based true RGB display device, such as figure 2 As shown, a light-emitting layer 4 is arranged between the hole transport layer 3 and the hole blocking layer 5 of the silicon-based real RGB display device;

[0059] The light emitting layer 4 includes a red light optical compensation layer 4-1, a common blue light emitting layer 4-2, a red light emitting layer 4-3 and a green light emitting layer 4-4;

[0060] Wherein, the red light optical compensation layer is disposed on the hole transport layer, but the upper surface of the hole transport layer is not completely covered by the red light optical compensation layer.

[0061] The red light optical compensation layer is set corresponding to the same width as the red light emitting layer, so as to realize optical compensation for the red light emitting layer and improve the color gamut of the silicon-based true RGB display device.

[0062] The red light emitting layer and the green light emitting layer are adj...

Abstract

The invention discloses a silicon-based real RGB display device and a display device. A light-emitting layer is arranged between a hole transport layer and a hole barrier layer of the silicon-based real RGB display device; the light-emitting layer comprises a red light optical compensation layer, a common blue light-emitting layer, a red light-emitting layer and a green light-emitting layer, wherein the red light optical compensation layer is arranged on the hole transport layer, but an upper surface of the hole transport layer is not completely covered by the red light optical compensation layer; the common blue light emitting layer is arranged on the red light optical compensation layer and the hole transmission layer which is not covered by the red light optical compensation layer, or the common blue light emitting layer is arranged below the hole blocking layer; problems that an existing silicon-based real RGB display device is low in performance and short in service life can be solved, a charge generation layer (CGL) does not need to be arranged in the device structure, and a crosstalk problem in a silicon substrate can be reduced.

Description

technical field [0001] The invention belongs to the technical field of RGB display devices, and in particular relates to a silicon-based real RGB display device and a display device. Background technique [0002] Compared with the traditional AMOLED display technology, the silicon-based OLED microdisplay is based on a single crystal silicon chip, and with the help of a mature CMOS process, the pixel size is smaller and the integration level is higher. It can be made into a near-eye display comparable to a large-screen display. products have received widespread attention. Based on its technical advantages and broad market, silicon-based OLED microdisplays will set off a new wave of near-eye displays in the military and consumer electronics fields, bringing unprecedented visual experience to users. [0003] Most of the existing high-ppi silicon-based OLED full-color products use WOLED (white OLED) + CF (color filter) technology, and the device structure used is generally a tw...
