Abstract

The red light micro light-emitting diode display panel comprises a driving backboard, an electrode array, an ultraviolet light micro light-emitting diode and a red light quantum dot layer. The electrode array is located on the driving backboard. And the ultraviolet light micro light-emitting diode is arranged on the electrode array. And the red light quantum dot layer is arranged on the ultraviolet light micro light-emitting diode. The red light micro light-emitting diode display panel of the discrete substrate display device achieves the technical effect of improving the quantum dot conversion efficiency through the ultraviolet light micro light-emitting diodes and the red light quantum dot layer. Therefore, the red light micro-light-emitting diode display panel, the green light micro-light-emitting diode display panel and the blue light micro-light-emitting diode display panel in the discrete substrate display device can all have enough external quantum efficiency, and the requirement of a full-color display device is met.

Description

technical field [0001] The present invention relates to a red light micro-light emitting diode display panel and a discrete substrate display device. Background technique [0002] Based on the miniaturization trend of today's micro-LED display devices, the influence of the decrease in the external quantum efficiency of micro-LEDs with size reduction is increasing. Taking a display device with three colors of red, blue and green as an example, it is difficult to improve the external quantum efficiency of red light-emitting diodes. In some discrete substrate display devices, the red light-emitting diode display panels are fabricated with structures such as mixed materials (eg, quaternary compounds) or nano-pillars. However, the above method has disadvantages such as high cost, poor efficiency and low yield. [0003] In view of this, how to provide a red light-emitting diode display panel that can overcome the above problems is still one of the goals of the current industry r...
