Problems solved by technology

[0003] The traditional test method needs to be powered on and off manually, and each product takes 1-2 seconds more time, which reduces the test efficiency; and power on without confirming whether the connection is OK, resulting in product damage; In addition, manual operation negligently electrifies Plugging and unplugging the product is very easy to damage the product
Traditional test methods are difficult to avoid product damage caused by misalignment and live plugging during testing, and frequent switching is required, resulting in low efficiency

Abstract

The invention discloses an LCM (liquid crystal module) testing control system based on capacitance monitoring, and relates to the technical field of LCM testing control. According to the system, a terminal capacitance monitor is connected with a power-on self-detecting unit through a sensing transmission module. The LCM testing control system comprises a product control driving unit and a terminal power supply control unit, the power-on self-detecting unit is connected with the product control driving unit through data signal analysis and signal driving transmission control module, and the terminal power supply control unit is connected with the product control driving unit through a signal transmission and electric control module. The LCM testing control system is used for performing analysis, so that efficient low-loss product testing operation is performed. The system drives a product testing system to automatically detect the connection state of a product, automatic power-on is performed when the tested product is connected, automatic power-off is performed when the product is taken, and damage to the product due to hot plugging or connection deviation is avoided.

Description

technical field [0001] The invention belongs to the technical field of LCM test control, in particular to an LCM test control system based on capacitance value monitoring. Background technique [0002] With the widening application of display screens, the company's order volume has increased significantly, and at the same time the cost of high-end products has become higher and higher, and new requirements have been put forward for the good efficiency of testing: 1. Improve efficiency; 2. Avoid testing Damage to the Product. [0003] The traditional test method needs to be powered on and off manually, and each product takes 1-2 seconds more time, which reduces the test efficiency; and power on without confirming whether the connection is OK, resulting in product damage; In addition, manual operation negligently electrifies Plugging and unplugging the product can easily damage the product. The traditional test method is difficult to avoid product damage caused by misalignme...
