Abstract

The invention discloses an LED (Light Emitting Diode) display screen module with separated lamp boards and driving boards. The LED display screen module comprises a circuit board, wherein the circuit board comprises a plurality of groups of LED lamp boards and a plurality of groups of driving boards, which are matched and connected mutually; each module comprises the plurality of groups of LED lamp boards and the plurality of driving boards, which are matched and connected mutually, and the large module is divided into a plurality of independent display units, so that signal interfaces and power supply interfaces can be more accurately butted; a PIN needle is not easy to bend and break and the connectedness of signals is enhanced; the frame loss rate of signal transmission is reduced and the time consumed in a module mounting process is reduced; meanwhile, the heat dissipation effect is further enhanced.

Description

technical field [0001] The invention belongs to the application field of electronic products, and in particular relates to an LED display module with separated lamp drive. Background technique [0002] In terms of circuit board design, the LED full-color display is generally composed of a light board and a driver board. There are currently two designs on the market, one is that the light board and the driver board are separated into two circuit boards, and the other is that the light board and the driver board are combined on one circuit board. [0003] The separation of the LED display light area means that the LED light and the driver chip are not on the same PCB board. The actual situation is that the PCB board on which the LED lamp is soldered is connected to the PCB board on which the driver chip is soldered through an array. Considering factors such as dot spacing, size, heat generation, etc., modules below P12 basically adopt the method of separating the lamp driver...
