Abstract

The invention relates to a drive-control LED digital display screen, and belongs to the technical field of display. The LED digital display screen comprises a PCB, LED patch lamps and a plastic shell; the PCB comprises a preset number of LED bonding pads which are arranged on the PCB, the LED bonding pads are correspondingly connected with a universal communication port connection socket through circuits, and the PCB further comprises an LED driving chip and positioning holes; each LED patch lamp is installed on the corresponding LED bonding pad of the PCB in an attached mode; the surface side of the plastic shell is provided with reflection cavities, the position of the center of the bottom cavity opening of each reflection cavity corresponds to one LED patch lamp, the back side of the plastic shell is provided with positioning columns, and the positioning columns and the positioning holes in the PCB are riveted in an aligned mode respectively. According to the LED digital display screen, the LED driving chip is integrated into the LED digital display screen, modularization and integration of the LED digital display screen and the drive control function are achieved, connection with an electric appliance control panel adopts the universal communication port connection socket instead of a guide needle pin connection mode of a traditional LED digital display screen, and installation is more standardized and simplified.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a drive-controlled LED digital display screen. Background technique [0002] The manufacturing process of the traditional LED digital display usually adopts the way of guide pins to connect the light source, PCB (Printed Circuit Board, printed circuit board) board and plastic shell and other components through the guide pin pins. The light source used is LED Epistar. When manufacturing the LED digital display, the staff binds the LED crystal to the PCB board through the binding process, and then conducts the positive and negative poles of the LED crystal by welding the metal welding wire, and finally the finished LED digital display is manufactured through The guide pins on the PCB board are connected to the electrical control board, such as figure 1 As shown, it shows a schematic diagram of a traditional LED digital display, where a is a guide pin, b is an LED chip, c is a ...
