Embodiment approach

[0050] However, for some other large-scale lamp panels, on the one hand, it does not require too high precision, on the other hand, because of the large imaging area, the coating workload will increase exponentially. At this time, the row-by-row (column) coating method is adopted Obviously not suitable, in order to deal with this situation, the present invention also discloses a second preferred embodiment, which specifically includes the following steps:

[0051] S21: Manufacture the screen plate according to the size determined in step S10, the screen plate is provided with a number of gaps, so that when it is docked with the bottom plate, it can only completely cover the light-emitting surface of the LED lamp bead, and does not cover the blank area on the bottom plate.

[0052] S22: Position and connect the screen board to the light board so that the light-emitting surface of the LED lamp beads is blocked by the screen board. The positioning pins on the board are docked to ...

Abstract

The invention discloses a manufacturing process for an LED lamp panel of low reflectivity, the LED lamp panel and an LED display screen. The LED lamp panel comprises a base plate, and a plurality of LED lamp beads are distributed on the base plate. The manufacturing method includes the following steps that S10, the size of the space between the LED lamp beads is determined; S20, the area, which is not distributed with the LED lamp beads, of the base plate is coated with a light absorption material according to the size determined by the step S10; S30, the light absorption material is solidified on the base plate. By means of the manufacturing process for the LED lamp panel of low reflectivity, the LED lamp panel and the LED display screen, the colors of the lamp panel can be kept consistent, the bad phenomena of chromatic aberration, color lumps and the like are avoided, light reflection can further be reduced at the same time, hence, the contrast ratio of a display is enhanced, and the development quality is improved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a manufacturing process of an LED lamp board; the invention also relates to an LED lamp board and an LED display screen. Background technique [0002] LED display is a flat panel display that realizes image display through light-emitting diodes. It is welcomed by people because of its advantages such as longevity, and is widely used in various fields in people's life and work. In the prior art, the light-emitting diodes are first uniformly fixed on the base plate, and then the base plate is integrally spliced ​​to form a light board. In order to achieve a better imaging effect, it is generally required that the color of the base plate be uniform and have a high contrast. However, in the actual production process, the color of the bottom plate is difficult to be completely consistent, resulting in adverse conditions such as chromatic aberration and color blocks on the screen. ...
