Abstract

The invention relates to a unit board and a manufacturing method thereof. The unit board manufacturing method comprises the following steps: die-bonding a plurality of pixel units on a circuit board,and enabling the pixel units to be arranged at intervals; spraying black ink to the gap between any pixel unit and the pixel units around the pixel unit to form a prefabricated unit board; and packaging the area where the pixel units and the black ink are located on the prefabricated unit board. The unit board manufacturing method is applied to the unit board. According to the unit board and the manufacturing method thereof, after the pixel units are die-bonded on the circuit board, a gap is formed between any pixel unit and the pixel units around the pixel unit, and the contrast ratio of theunit board can be improved by spraying black ink to the gap. After ink is sprayed to the gap formed between any pixel unit and the pixel units around the pixel unit, the area where the pixel units andthe black ink are located is packaged, and therefore, the area where the pixel units and the black ink are located can be protected.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a unit board and a manufacturing method thereof. Background technique [0002] Large-sized micro-pitch display screens are all spliced ​​by unit boards. The color reproduction of the unit boards plays a decisive role in the display effect of the display. However, the current unit boards generally have the problem of low contrast, which leads to low color reproduction. , affecting the display effect. Contents of the invention [0003] Based on this, it is necessary to provide a method for manufacturing a unit board and a unit board for improving the contrast of the unit board. [0004] Its technical scheme is as follows: [0005] A method for making a cell plate, comprising: [0006] Solidifying a plurality of pixel units on the circuit board, and arranging the plurality of pixel units at intervals; [0007] spraying black ink in the gap between any one of the pixel ...
