Problems solved by technology
However, whether it is a GOB film or a COB film, the material of the encapsulation layer 103 covering the LED light source 102 is a soft material, and the hardness basically cannot exceed 1H.
Therefore, display defects such as air bubbles and dents may appear in the encapsulation layer 103, causing wrinkles or fine dents in the coating layer 105 covering the encapsulation layer 103 to fail to achieve the desired optical effect; even the back adhesive layer 104 and the encapsulation layer Problems such as cavities, air pockets and delamination caused by material mismatch between 103 also make the coating layer 105 uneven and fail to achieve the desired performance

The invention provides an LED display module and a manufacturing method thereof. The manufacturing method comprises the following steps: providing a substrate and an LED light source; fixing the LED light source on the front side of the substrate; forming an encapsulation layer around the LED light source and on the front side of the substrate; A support layer is formed on the front side of the encapsulation layer, so that the support layer has a flat front side; a coating layer is formed on the front side of the support layer. In the LED display module manufactured by the manufacturing method of the present invention, a support layer is added between the encapsulation layer and the coating layer, and the support layer has a flat front surface, and the flatness of the front surface will not be affected by external Therefore, when the coating layer is laminated on the front surface of the support layer, it can ensure that the coating layer has an ultra-high flatness, and avoid wrinkles or fineness of the coating layer. depression, so as to achieve the desired optical display effect and application performance.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to an LED display module and a manufacturing method thereof. Background technique [0002] With the in-depth study of tiny dot pitch displays such as Mini LED (Mini Light Emitting Diode, sub-millimeter light-emitting diode), Micro LED (Micro Light Emitting Diode, micro light-emitting diode) and the refinement of people's cognition, people's current There are higher requirements for the optical performance of the small-pitch display adjacent to the tiny dot pitch, for example, whether it is possible to obtain a high-definition display comparable to OLED (Organic Light Emitting Diode, organic light-emitting diode), ultra-high contrast, black level and ink color consistency properties, etc., and whether it can be used for 3D display or touch control. This greatly expands the application scenarios of such small-pitch displays. Small-pitch seamless LED display modules with...
