Abstract

The invention discloses a micro light emitting diode display panel and a display device, wherein the micro light emitting diode display panel comprises: an upper substrate, a lower substrate, an upper electrode, a lower electrode, a first micro light emitting diode, a second micro light emitting diode and a third micro light emitting diode A light emitting diode and an image sensor array, wherein the upper substrate and the lower substrate are arranged at intervals in the first direction; the upper electrode is arranged on the side of the upper substrate close to the lower substrate, and the lower electrode is arranged on the side of the lower substrate close to the upper substrate; The first micro light emitting diode, the second micro light emitting diode, the third micro light emitting diode and the image sensor array are all arranged between the upper electrode and the lower electrode, and the first micro light emitting diode, the second micro light emitting diode, the third micro light emitting diode and the image sensor array are arranged at intervals along the second direction. The micro light-emitting diode display panel provided by the present invention not only has excellent display performance, but also has a scanning function.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a micro light emitting diode display panel and a display device. Background technique [0002] The use of LED (Light Emitting Diode, light emitting diode) in display elements originates from the application of TFT-LCD (thin film transistor-liquid crystal display, thin film transistor-liquid crystal display) backlight module. TFT-LCD is a non-self-illuminating flat-panel display, and its component functions are similar to light control switches, requiring a backlight module to provide a light source. Since TFT-LCD began to flourish in the 1990s, some manufacturers have used LEDs as the backlight of liquid crystal displays, which have the characteristics of high color saturation, power saving, and thinness. However, due to factors such as high cost, poor heat dissipation, and low photoelectric efficiency, it was not widely used in TFT-LCD products. [0003] By the 2000s, white L...
