Abstract

The invention relates to an LED display panel, a production method and electronic equipment. In the production method of the LED display panel, a method of respectively producing a driving circuit layer and flip LED chips at first and then transferring the flip LED chips to the driving circuit layer is abandoned, the flip LED chips are arranged on a substrate to form an LED chip layer, and then the driving circuit layer is directly formed on the LED chip layer. The manufacturing process of the driving circuit layer and the process of binding the flip LED chip and the driving circuit layer are combined together, the process of transferring the flip LED chip and binding the flip LED chip to the driving circuit layer is omitted, the manufacturing process of the LED display panel is simplified, and the production efficiency of the LED display panel is improved. In addition, the process of welding and binding the flip LED chips is omitted, the problem that the driving circuit layer deforms due to the influence of a high temperature can be avoided, and the quality of the LED display panel is further maintained.

Description

technical field [0001] The invention relates to the field of display, in particular to an LED display panel, a preparation method and an electronic device. Background technique [0002] When preparing the LED display panel, the LED chip prepared on the growth substrate will be transferred to the driving backplane after a series of processes such as transfer and crystal expansion, and the bump metal (Bump) or bump will be melted at high temperature. The lower metal (Under bump metal, UBM) realizes the bonding with the driver backplane. The manufacturing process of such an LED display panel is complicated. Especially in the process of welding the electrodes of the LED chip by melting the bump at a high temperature, phenomena such as offset, rotation and tilt of the LED chip are prone to occur, which leads to the problem of poor quality of the LED display panel. [0003] Therefore, how to simplify the manufacturing process of the LED display panel and improve the quality of th...
