Embodiment Construction

[0031] The embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] like figure 1 shown, figure 1 It is a schematic structural diagram of a display module. The display module includes an array substrate 11 , and the array substrate 11 includes a base 111 and a thin film transistor 112 disposed on the surface of the base 111 . A first electrode 12 is provided on the surface of the array substrate 11 for electrically connecting with the second electrode 131 of the Micro-LED 13 by eutectic welding. In order to a...

Abstract

The invention discloses a display module and a manufacturing method thereof. According to the technical scheme, a light absorption layer is arranged on an array substrate, a part of a first electrode is exposed out of the light absorption layer, the thickness of the light absorption layer is larger than the sum of the thickness of the first electrode and the thickness of a conductive adhesive on the surface of the first electrode, and a mounting groove is formed in the side, away from the array substrate, of the light absorption layer; and the light-emitting element is installed in the installation groove and connected with the first electrode through the conductive adhesive. The light absorption layer surrounds the side wall of the light-emitting element, so that the crosstalk problem of emergent light of the side wall of the light-emitting element can be avoided. In addition, the light absorption layer further comprises a diversion trench, the diversion trench can collect the overflowed conductive adhesive when the light-emitting element is installed, and the problem that other areas are polluted by the overflowed conductive adhesive can be avoided.

Description

technical field [0001] The present application relates to the technical field of display devices, and more particularly, to a display module and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display function are widely used in people's daily life and work, and become an indispensable tool for people today. The main component of the electronic device to realize the display function is the display module. [0003] Micro-LED (Micro Light Emitting Diode) is a new generation of display elements. Compared with traditional multiple OLEDs (Organic Light Emitting Diode), it not only has higher luminous brightness and luminous efficiency, but also has lower power consumption. Micro-LED is to thin, miniaturize and array LED, and its size is less than 100μm. [0004] In the existing display modules made of Micro-LEDs, the separately prepared Micro-LEDs are generally transfe...
