Description

technical field

[0001] The embodiments of the present invention relate to the field of display technology, and in particular to a light emitting diode chip array and a display panel. Background technique

[0002] Micro Light Emitting Diode (micro-LED / ΞΌLED) display panels integrate light emitting diode (Light Emitting Diode, LED) chips with a size of less than 100 microns on a substrate as display pixels to realize image display. Each display pixel can be addressed and individually driven to light up, so the Micro-LED display panel is a self-illuminating display panel.

[0003] In the prior art, a Micro-LED display panel includes an LED chip array and a driving backplane. Due to the high requirements for the number of pixels (Pixels Per Inch, PPI) of the Micro-LED display panel, the display pixels are usually small, and the distance between adjacent LED chips is very small. Therefore, the existing LED chip array is bonded to the driving backplane ( When bonding), there is a...
