Abstract

The invention provides a light-emitting diode chip and an application thereof. The light-emitting diode chip comprises a plurality of light-emitting diodes, a plurality of electrical connecting pieces and a packaging body, wherein the plurality of electrical connecting pieces are respectively connected with the plurality of light-emitting diodes; the packaging body is used for integrating the plurality of light-emitting diodes into the light-emitting diode chip, and the plurality of light-emitting diodes have the same light color. According to the light-emitting diode chip and the application thereof provided by the invention, the transfer printing yield in the manufacturing process of a light-emitting diode panel is improved.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to a light emitting diode chip and its application. Background technique [0002] Micro light-emitting diodes (Micro LEDs) are the light sources for next-generation displays that are currently under intense research. Micro LED displays have the advantages of low power consumption, high brightness, ultra-high resolution, ultra-high color saturation, fast response, low energy consumption, and long life. In addition, the power consumption of a micro-LED display is about 10% of that of a liquid crystal display (LCD) or 50% of that of an organic light-emitting diode display (OLED). Compared with the same self-luminous OLED, the brightness is 30 times higher, and the resolution can reach 1500PPI (pixel density, Pixels Per Inch). These obvious advantages of the micro light-emitting diode display make it expected to replace the current OLED and LCD and become the next-generation display. Mi...
