    Abstract: An exemplary liquid crystal display device (20) includes a liquid crystal display panel (200), a flexible printed circuit (270) and a driving chip (210). The flexible printed circuit includes a conductive line (273). The driving chip includes an interface circuit (230) and an analog-to-digital circuit (260), the analog-to-digital circuit is configured for receiving an analog operating mode signal via the conductive line and transforming the analog operating mode signal to a digital operating mode signal, and providing the digital operating mode signal to the interface circuit. The digital operating mode signal determines an operating mode of the liquid crystal display device.
