Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a micro light-emitting diode display panel and a display device. 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, a third micro light-emitting diode and an image sensor array, wherein the upper substrate and the lower substrate are arranged in a spacing mode in a first direction; the upper electrode is arranged at the side, close to the lower substrate, of the upper substrate, and the lower electrode is arranged atthe side, close to the upper substrate, of the lower substrate; 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 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 andthe image sensor array are distributed in a spacing mode along a second direction. The micro light-emitting diode display panel has a scanning function in addition to excellent display performance.

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...
