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 自带学习调教功能，用户接线完毕后，只需设置输出电流值，按下学习功能键，即可进入自动适应电压功能。学习成功后，按下 ON/OFF 键就能进行测试。这种智能化的设计，相较于人工调节电压 / 电流，具有更好的防呆效果，有效减少了因操作失误导致的测试误差。

在性能参数方面，DH-701 的输入电压为 AC200V – 240V，低电流输出为 5 – 200UA/1CH8CH，高电流输出为 120MA/1CH8CH，总功率输出为 300W，输出电压为 DC10 – 320V 且能自动跟踪，输出接口为 PH2.54*10pin，面板显示测试状态。通过实际应用验证，DH-701 能够准确检测液晶模组背光的各项性能指标，为提高液晶模组的背光质量提供了有力支持。
