Abstract

The invention discloses an LED display screen module test system which comprises a test platform, a current detection device, a voltage detection device, an overcurrent protection device, an overvoltage protection device and a power supply module, wherein the current detection device, the voltage detection device, the overcurrent protection device, the overvoltage protection device and the power supply module are arranged on the test platform. The current detection device and the voltage detection device are used for detecting current and voltage values of an LED display screen module in real time. When the current and voltage values of the LED display screen module surpass the maximum current and voltage values respectively, the overcurrent protection device and the overvoltage protection device work and cut off the power supply of the power supply module. The test system allows varies circuit boards to be fixedly arranged on the test platform in the sample testing process, thereby preventing short circuit due to mutual contact, saving space and improving reliability; and the overcurrent and overvoltage protection circuits are added, so that reliability and safety of the system are enhanced.

Description

technical field [0001] The invention discloses a LED display screen module testing system, in particular relates to a testing system for LED factory prototype testing, and belongs to the field of electronic equipment. Background technique [0002] The LED industry is a rapidly developing emerging industry. LED display is widely used in advertising media, stage background, building decoration, traffic information, sports venues, etc. With the growing market demand for LED display screens, more and more manufacturers have emerged. Although the LED display has developed rapidly in recent years, as an emerging industry and the excessive pursuit of interests by various manufacturers, the LED display industry does not have a unified industry standard. Therefore, the supporting facilities of the LED display , testing facilities have not been well developed. [0003] LED display manufacturers develop their own products according to their own company conditions and customer requir...
