Currently, most digital tube applications are to weld the digital tubes on the circuit board, and the driver chip and the digital tube are welded separately. In this production process, both the driver chip and the digital tube need to occupy a certain space on the circuit board, which may increase the size of the circuit board, which is not conducive to the miniaturization and integration of the product. It also requires two weldings, and the manufacturing process of the digital tube display module is more complicated. Utility Model Content
