Abstract

The invention provides a light-emitting diode chip and a manufacturing method thereof, and belongs to the technical field of semiconductors. The light-emitting diode chip further comprises a plurality of light-emitting adjusting assemblies located on a P-type semiconductor layer, the light-emitting adjusting assemblies are arranged on the P-type semiconductor layer in an array mode, the structures of the light-emitting adjusting assemblies are the same, each light-emitting adjusting assembly comprises an indium tin oxide unit, a plurality of light-transmitting walls and a plurality of first control wires, the plurality of light-transmitting walls are arranged at intervals in the circumferential direction of the indium tin oxide unit, one end of each first control wire is connected with one light-transmitting wall, the first control wires are used for receiving first control signals and transmitting the first control signals to the light-transmitting walls, and the first control signals are used for changing the size of an electric field in the light-transmitting walls so as to adjust the light transmission of the light-transmitting walls. The LED chip can control the light emitting direction of the side surface of the light-emitting diode chip, so that the display screen reaches a display angle expected by a user, the use experience of the user is improved, and the leakage of display information is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductors, in particular to a light emitting diode chip and a manufacturing method thereof. Background technique [0002] A light emitting diode (English: Light Emitting Diode, referred to as: LED) is a semiconductor device that can emit light. By using different semiconductor materials and structures, LEDs can cover a full color range from ultraviolet to infrared, and have been widely used in economic life such as display, decoration, and communication. [0003] At present, the display screens of personal electronic products such as mobile phones are gradually adopting LED display planes. The current LED chips all emit light directly to form a display screen, and the viewing angle of the light can reach about 160 degrees, and there is no difference in each direction. However, if there is no difference in the display screen, people around the user can also clearly see the information on th...
