LED display screen module and preparation method thereof

Abstract

The invention discloses an LED display screen module and a preparation method thereof, relates to a display screen technology, and aims at solving the problems that a display screen is large in heat productivity and uneven in temperature distribution and consequently the phenomena of local high temperature, display chromatic aberration and the like are prone to occurring in daily work. The LED display screen module is characterized in that the LED display screen module comprises a dot matrix panel, a heat dissipation substrate and a mounting shell; the heat dissipation substrate is embedded in the mounting shell and is detachably connected with the dot matrix panel; a plurality of caulking grooves are formed in the peripheral wall of the mounting shell, and a plurality of elastic fasteners which are embedded in the caulking grooves to be connected with the mounting shell are arranged on the peripheral wall of the dot matrix panel; and a power supply module, a stress detection module, a temperature detection module and a cooling fan are arranged in the mounting shell. The temperature detection module collects the temperature of the heat dissipation substrate, the heat dissipation fan can be driven to adjust the rotating speed along with the temperature change on the heat dissipation substrate through the pulse generation circuit, more energy is saved, and heat dissipation of the heat dissipation substrate can be accelerated when heat is accumulated.

Description

technical field [0001] The invention relates to display screen technology, more specifically, it relates to an LED display screen module and a preparation method thereof. Background technique [0002] The continuous development of society and the vigorous advocacy of the country have made the LED industry one of the most active industries today, and LED display products have gradually entered various fields of society and life. At the same time, with the innovation and development of LED display technology, the small-pitch seamless connection LED display module with high resolution per unit area has become the mainstream product of LED display, which can display higher-definition graphic images And video, it can also display more video and image images, especially in the application of image stitching, which can achieve seamless and arbitrary large-area stitching. [0003] At present, due to the dense arrangement of chips and IC components on the back of the LED display, th...
