Abstract

In the manufacturing of electronic product, backlight quality always affects the final rate of good product. To date, the backlight qualityis usually detected by manual eyes.In this article,an auto lighting device used forbacklightsystemdetectionwasfabricatedwith STM32 chip which basedon the ARM core. Firstly,the FPC was pressed closely on the dense goldfinger.Then, positive or negative weak current signal was sent respectively fromthe transistor array which was controlled by the STM32 chip. Thirdly, the positive or negative of FPC electrode wasjudged intelligently by the STM32 chip.Finally, according to the judgment results, the operating power with corresponding electrode polaritywas provided tolight the backlight system.The auto lighting detection of the backlight quality could be realized perfectly by this device.
