Abstract

The invention provides a display panel and a display device. The display panel comprises a driving backboard, a driving circuit, a first electrode layer, a micro LED, a second electrode layer and a binding layer. The first electrode layer on the driving circuit is provided with a first protruding structure, and the second electrode layer under the micro LED is provided with a second protruding structure. The binding layer is arranged between the first electrode layer and the second electrode layer. The contact area between the binding layer and the first electrode layer or the contact area between the binding layer and the second electrode layer is increased, so that the problem that the micro LED falls off is solved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Compared with the current LCD and OLED display devices, Micro-LED display devices have the advantages of fast response, high color gamut, high resolution, and low energy consumption. But its technical difficulties are many and complex, especially its key technology: mass transfer technology. [0003] Micro LED chips need to be transferred to the required positions one by one after the production is completed. The number of micro LED chips to be transferred is large and the position accuracy after transfer is high, which consumes a lot of resources. With the development of technology, mass transfer technology has developed many technical branches, such as electrostatic adsorption, laser burning and so on. [0004] Mass transfer technology is to bind a huge number of micro-LED chips to the drive ci...
