Abstract

The present invention provides a light-emitting diode display, which includes a first substrate, on which a pixel unit is arranged, and the pixel unit includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, and the green sub-pixel is a green micro-luminescent Diodes, the green micro-LEDs include: an initial green micro-LED; a green color-resist covering layer, the green color-resist covering layer covers the outer surface of the initial green micro-LED, the green color-resist covering layer has at least An opening; and, a first contact electrode disposed on the green color-resist covering layer, and the first contact electrode is electrically connected to the initial green micro-LED from the at least one opening; wherein, the green color-resist covering layer It is used to filter out the light with a wavelength of 600nm to 650nm in the light emitted by the initial green micro light emitting diode; thereby improving the display quality of the display.

Description

technical field [0001] The present invention relates to a light emitting diode display, more particularly to a display of micro light emitting diodes. Background technique [0002] With the advancement of technology, the display has gradually changed from a relatively thick cathode ray tube (Cathode Ray Tube, CRT) display to a relatively flat and thin liquid crystal display (Liquid Crystal Display, LCD), plasma display (Plasma Display Panel, PDP) , organic light emitting diode (Organic Light Emitting Diode, OLED) display or micro light emitting diode (Micro LED) display, etc. [0003] Full-color light-emitting diode displays can use miniaturized light-emitting diodes (Micro LEDs) to form red, green, and blue sub-pixels, without the need for color filters in traditional liquid crystal displays. This structure is simpler and smaller. Moreover, the light emitting diode can be fabricated on a flexible substrate, so that the light emitting diode display is not only light and thi...
