Title
(EN) LIQUID CRYSTAL TELEVISION DEVICE AND SYSTEM
Abstract
(EN)

The present disclosure recites a liquid crystal TV device and system. The liquid crystal TV device has an LCD body, a T-CON control circuit board and a signal conversion circuit board. The signal conversion circuit board is used to convert a video signal receiving from the content providing apparatus to a signal to be displayed for the LCD body, and to transmit the signal to be displayed to the T-CON control circuit board. The T-CON control circuit board drives the LCD body to display images according to the signal to be displayed. Further, the liquid crystal TV device does not have an SOC main control circuit board. With the aforementioned way, the present disclosure can lower the cost of the TV and is beneficial to simplify the internal structure of the TV device.
