Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and in particular to an anti-interference circuit module of an LED screen. Background Art

[0002] In simple terms, the LCD module is a screen plus a backlight component. The display component of an LCD TV is the LCD module. The principle of LCD display is that the backlight component emits uniform surface light, which is transmitted to our eyes through the LCD screen. The function of the screen is to process these lights by pixels to display images. There are at least the following disadvantages in the use of existing LED display screens: 1. During the use of existing LED display screens, they are easily affected by external electromagnetic interference, causing abnormal display of the LCD circuit module, affecting the normal use of the LCD circuit module, and reducing practicality; 2. The existing LED display screens will use anti-blue light panels when in use, but the anti-blue light panels are directly fixed on the LCD circuit module, which is not convenient for disassembly and replacement. Therefore, when the anti-blue light panel is worn, it will affect the visual effect of the LCD module. Therefore, we have launched an LED screen anti-interference circuit module.
