Abstract

The invention discloses an LED (light emitting diode) display screen unit, an assembling method and an LED display screen. The LED display screen unit comprises an after-body support frame, a PCB (printed circuit board) board and two magic tapes, wherein the after-body support frame comprises a dead plate and multiple frame bodies sequentially connected from head to tail, the dead plate comprises a front end face and a rear end face, the PCB board is fixed to the front end face, said multiple frame bodies are fixed to the rear end face, each frame body comprises an outer side on which multiple horizontal reinforcing ribs and multiple longitudinal reinforcing ribs are arranged, each horizontal reinforcing rib and each longitudinal reinforcing rib are intersected, each outer side is further provided with a plurality of deflector holes passing through the corresponding frame body, and the after-body support frame is provided with at least one metal screw connected with the PCB board; the after-body support frame further comprises two opposite connecting end faces, each connecting end face is provided with a clamping slot, each magic tape comprises a back glue line and a hairy layer arranged on the back glue, and each back glue line is fixed to the corresponding clamping slot.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to an LED display unit, an assembly method and an LED display. Background technique [0002] LED (light emitting diode abbreviation) display unit is favored by a wide range of users because of its high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and stable performance. At present, the rear support frame of the LED display unit is made of polycarbonate (hereinafter referred to as PC material), and its mechanical strength is poor. And because the PC material is an insulating material, it is difficult for the rear body support frame made of the PC material to release the static electricity generated by the LED display unit. In addition, when the LED display unit is used in an outdoor environment, especially in a rainy day, water tends to accumulate on the back of the rear body support frame and the hollow frame reinforcing rib, which...
