Abstract
The present invention provides a light-emitting device, a manufacturing method thereof, and a display panel. The light-emitting device includes a semiconductor layer, and the semiconductor layer includes a first semiconductor layer, a light-emitting layer, and a second semiconductor layer stacked; an insulating layer, and the insulating layer includes: a first semiconductor layer. A retaining wall, a second retaining wall and a third retaining wall, the first retaining wall surrounds the outer wall of the semiconductor layer, the second retaining wall at least partially protrudes from the middle area of the surface of the second semiconductor layer, the third retaining wall and The second barrier is spaced apart; the first electrode, the first electrode covers the surfaces of the first barrier and the third barrier that are not in contact with the semiconductor layer and is connected to the first semiconductor layer; the second electrode, the second electrode covers The second barrier is also connected to the second semiconductor layer. According to the light-emitting device of the embodiment of the present invention, most of the semiconductor layer is surrounded by the metal used to make the electrodes, and the metal is used to reflect the light that hits the side and bottom, so that the brightness of the light-emitting device can be effectively improved without increasing the power, thereby reducing Backplane power consumption.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a light-emitting device, a manufacturing method thereof, and a display panel. Background technique [0002] LED display technology has developed into one of the hot spots of future display technology. Micro LED display technology has independent pixel control, independent lighting control, high brightness, low power consumption, ultra-high resolution and high color. The bonding technology between the Micro LED and the backplane determines the product yield and repair difficulty. The current mainstream technology is to fabricate microtubes at the N-type semiconductor end and the P-type semiconductor end after the light-emitting device is fabricated to bond with the display panel. However, such a design requires sacrificing a certain light-emitting area, thereby reducing the brightness of the light-emitting device. SUMMARY OF THE INVENTION [0003] In view of this, the ...
