Design and Implementation of Intelligent Tester for LED Backlight LCD Display Driving Power

Abstract:

In accordance with the requirement of LED LCD driving power test and the basic principle of digital DC electronic load and combined with the trend of intelligentization, miniaturization, communication of electronic load, a new scheme of intelligent tester for LED LCD driver power based on PIC is proposed. It implements working modes of setting current, testing voltage, testing current, testing frequency, multi-channel transmission etc. Intelligent testing for ten states of LED LCD's four outputs under two power mode is supported. It can also send test data to upper computer for analysis with RS485 bus.
