Abstract

The invention relates to an LED electronic display screen circuit board waterproof method and a display module. The display module comprises a bottom case, a face shield and an LED circuit board, the LED circuit board is installed on the front surface of the bottom case, and waterproof glue is poured into the front surface of the LED circuit board. In order to prevent rainwater from entering the back side of the bottom case, the inner side of a framework of the bottom case is provided with a base plate, positions, of the base plate, corresponding to the a signal port and a power supply port of the LED circuit board are provided with a first pass-through opening and a second pass-through opening, when the LED circuit board is installed on the bottom case, the signal port and the power supply port pass through the pass-through openings, and waterproof glue is poured into the periphery of the signal port and the power supply port, thus, the back side of the display module is waterproof, in order to ensure that a driving integrated circuit on the LED circuit board maintains a good heat dissipation effect, the position, of the base plate, corresponding to the driving integrated circuit on the LED circuit board is provided with a heat dissipation block, and the driving integrated circuit on the LED circuit board clings to the inner surface of the heat dissipation block. Compared with the existing products, the display module is advantaged in that a waterproof aim is reached, and the heat dissipation problem is solved.

Description

technical field [0001] The invention relates to the field of LED electronic display screens, in particular to a method for waterproofing circuit boards of LED electronic display screens and a display unit module. Background technique [0002] Outdoor LED display integrates microelectronics technology, computer technology and information processing. It has bright colors, wide dynamic range, high brightness, low working voltage, low power consumption, long life, impact resistance, bright colors and stable and reliable work. Advantages, become the most advantageous new generation of outdoor large-scale display media. [0003] Outdoor LED electronic display is composed of a large number of light-emitting diodes and electronic components. Its waterproof, dustproof and anti-corrosion become an important technical link of outdoor LED electronic display. Usually, the waterproof level is required to reach IP65. In the current products, the display module of the LED electronic displa...
