Problems solved by technology

[0005] In order to solve the above problems, the present invention provides an array substrate and a transfer method. The array substrate can avoid the contact between the micro-devices that do not need to be transferred and the array substrate by providing the bonding bumps, thereby solving the problem of ACF bonding faced by ACF bonding. It is easy to have holes or tears, and it is impossible to repair the Micro LED

Abstract

The present invention provides an array substrate and a transfer method. The array substrate is provided with a plurality of bonding bumps, and each of the bonding bumps is configured to at least hold a micro device on its surface, so that The held micro-device is electrically connected to the array substrate; the array substrate and the transfer method of the present invention enable the array substrate to contact the micro-device only through the bonding bumps, thereby avoiding the need for transfer of the micro-device The contact with the array substrate can further solve the problems faced by ACF bonding that the ACF is prone to holes or tears and cannot be repaired for Micro LEDs.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a transfer method. Background technique [0002] Compared with OLED displays, Micro LED displays have the advantages of high reliability, high color gamut, high brightness, high transparency, and high PPI. In addition, the packaging requirements of Micro LED displays are low, and it is easier to achieve flexible and seamless splicing displays. Therefore, Micro LED display is a future display rate with great development potential in the future. [0003] figure 1 It is a process flow chart of the existing transfer method. like figure 1 As shown, in the existing transfer technology, the contact area between the Micro LED array device 20 and the ACF (Anisotropic Conductive Film) adhesive layer 11 of the array substrate 10 is large, making it difficult for the Micro LED 21 to be separated after selective transfer, and it is also easy to cause the ACF adhesi...
