Furthermore, a first USB interface is connected to the first driving module, the infrared frame is connected to the first driving module through the first USB interface, and a second USB interface capacitive screen is connected to the second driving module through the second USB interface.

Further, still be connected with fingerprint management module on the main chip, install fingerprint identification module on capacitive screen and the infrared frame, fingerprint identification module is connected with fingerprint management module, obtains control box service authority through fingerprint verification.

Furthermore, a storage module is connected to the main chip, and video software downloaded through the RJ45 module or the WIFI module is stored in the storage module.

Furthermore, the video signal processing module is connected with an HDMI output interface and a DP output interface, and the liquid crystal television is connected with the video signal processing module through the HDMI output interface or the DP output interface.

Further, still have the power conversion module in the control box, the power conversion module with RJ45 module, WIFI module, first drive module, second drive module electric connection convert the commercial power into the 5V DC power and supply power for the control box.

Furthermore, the utility model discloses LCD TV touch device simple structure, with low costs, the commonality is strong to but extremely low cost upgrades ordinary LCD TV for the intelligent TV of touch-control, but has two kinds of output interfaces of HDMI and DP and is applicable to common LCD TV on the market, makes it satisfy two kinds of touch-control forms of electric capacity screen or infrared frame through two kinds of USB drive module.
