Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] figure 1 It is a schematic diagram of the preparation process of an existing Micro LED display panel. see figure 1 , the display panel includes a driving backplane 11 and a Micro LED chip 10 arranged on the driving backplane 11. The driving backplane 11 is usually grown on a substrate such as glass / flexible substrate / silicon / PCB by CVD, PVD and other technologies to grow TFT / MOS and other functional devices, its temperature resistance is not high, and the preparation of Micro LED chip 10 uses MOCVD or AL...

Abstract

The invention discloses a light emitting diode display panel, a preparation method thereof and a display device. The light emitting diode display panel comprises a metal substrate, a plurality of inorganic light-emitting diodes located on the first side of the metal substrate and a plurality of driving units located on the second side of the metal substrate, and the first side and the second sideare oppositely arranged. The inorganic light emitting diode comprises a first semiconductor layer and a second semiconductor layer, the metal substrate at least comprises a first electrode part and asecond electrode part which are insulated from each other, the first electrode part is electrically connected with the first semiconductor layer, and the second electrode part is electrically connected with the second semiconductor layer; the driving unit is electrically connected with the first electrode part, or the driving unit is electrically connected with the second electrode part. Accordingto the light emitting diode display panel, the preparation method thereof and the display device, inorganic light-emitting diodes prepared on other native substrates do not need to be transferred through a huge transfer technology, and the problems of low efficiency and yield caused by the adoption of the huge transfer technology in the prior art are solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a light emitting diode display panel, a manufacturing method thereof, and a display device. Background technique [0002] Micro light-emitting diode (Micro light-emitting diode, Micro LED) is a light-emitting diode with a size of micron. Due to the small size of Micro LED, it can be used as a pixel on a display panel. The display panel prepared by using Micro LED can be It is called Micro LED display panel. Compared with Organic Light-Emitting Diode (OLED) display panels, the service life and viewing angle of Micro LED display panels are superior to OLED display panels, so Micro LED display technology has become the focus of research in the field of display technology. [0003] In the prior art, the Micro LED chip particles are transferred from the original substrate to the substrate with the driving circuit through the mass transfer technology. The tr...
