Problems solved by technology

The electrical drive IC is mainly used to adjust the luminous efficiency of the light-emitting diode through the use of algorithms, while the pixel circuit mainly uses TFT, and each TFT component has a difference in capability, which makes it necessary to use a compensation circuit to overcome the process Defects caused by TFT, but the use of compensation circuits in TFT will also have reliability problems
Compensation by the driver IC will mainly generate additional costs and increase the production cost.

Abstract

The invention belongs to the technical field of semiconductors, and provides a display device and a preparation method thereof, wherein the display device comprises a substrate, light-emitting diodes and a light reflecting part; the light-emitting diodes are arranged on the substrate, and the light reflecting part is arranged around the light-emitting diodes; and the reflecting area of the light reflecting part is set according to the light-emitting efficiency of the light-emitting diodes. According to the scheme, the light-emitting efficiency of the light-emitting diodes of different colors is balanced by regulating and controlling the reflecting area of the light reflecting part, the brightness of the light-emitting diodes is balanced, and the display effect of the display device is improved; the mode of regulating and controlling the light-emitting efficiency of the light-emitting diodes of different colors is compensated by applying an optical reflection physical phenomenon; and compared with an existing method for driving an IC and a pixel circuit, the method of compensating electrically has the advantages that the stability is better, and the cost is lower.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductors, in particular to a display device and a manufacturing method thereof. Background technique [0002] A Light Emitting Diode (LED) is a device that converts an electrical signal into a form of infrared rays, visible light beams, etc. by utilizing the properties of compound semiconductors. LEDs are widely used in home appliances, remote controls, electronic display panels and various automation devices. As LEDs are used in a wide range of electronic devices, the application field of LEDs is constantly developing towards miniaturization technology, which also makes the display performance requirements of LEDs more and more stringent. [0003] There are differences between different colors of light-emitting diodes. In the light-emitting curves of RGB three-color light-emitting diodes, the linearity of red light and blue-green light are different, and the luminous efficiency of the thr...
