The backlight quality of LCD module directly affects the display effect, so backlight testing is an important part of the LCD module production process. Xinrunjing Technology's LCD module backlight test solutions, focusing on providing companies with efficient and accurate means of backlight testing.

The LCD Module LED Smart Lighter DH-701 is the core device of this solution. It provides 8CH constant current source output, which can directly drive the backlight tube to light up and ensure the stable supply of backlight. The device is equipped with buttons and LED display, the operation interface is simple and intuitive, which is convenient for users to set parameters and check the status.

DH-701 comes with a learning tuning function, after the user has finished wiring, just set the output current value and press the learning function key to enter the automatic voltage adaptation function. After successful learning, press the ON/OFF key to test. This intelligent design, compared with manual voltage/current adjustment, has a better anti-dumbing effect and effectively reduces the testing errors caused by operating errors.

In terms of performance parameters, the DH-701 has an input voltage of AC200V - 240V and a low current output of 5 - 200UA/1CH.8CH, high current output 120MA/1CH8CH, the total power output is 300W, the output voltage is DC10-320V and can be automatically tracked, the output interface is PH2.54*10pin, the panel shows the test status. Through practical application verification, DH-701 can accurately detect the LCD module backlight performance indicators, to improve the quality of LCD module backlight provides strong support.
