Detailed Description

Referring to fig. 1, the utility model provides a double-sided screen television system, which comprises a main control board, a power module and a TCON drive board, wherein the power module and the TCON drive board are connected with pins corresponding to the main control board, and two 4k glass display screens 7 respectively connected with the corresponding TCON drive boards; the main control board comprises an RK3288 main board 1; the power supply module is independently arranged outside the television.

The RK3288 mainboard 1 supports two-way LVDS output to drive two screens, so that the RK3288 mainboard 1 is selected as a chip scheme, and the cost of one core mainboard is saved. The RK3288 mainboard 1 is provided with WiFi and wired network port interfaces, and meets the internet access requirements of a double-sided screen television. An infrared remote control interface is matched, and the requirement of operating the double-sided screen television by using an infrared remote controller is met. The RK3288 mainboard 1 also outputs 4 paths of USB, wherein one path of USB meets The OTG upgrading requirement (OTG is The abbreviation of On-The-Go, and is mainly applied to The connection between different devices or mobile devices for data exchange).

The power supply module comprises a rectifier 2, a shunt module 3, a constant current module 4 and a DC/DC power supply converter 5; the AC power is converted into direct current power through the rectifier 2 and is transmitted to the shunt module 3; one output end of the shunt module 3 is connected with the constant current module 4, the output end of the constant current module 4 is used as a constant current source, and the other output end of the shunt module is connected with the DC/DC power converter 5 to supply power for the RK3288 mainboard 1.

The TCON driver board includes a 2k-4kTCON driver 6 for converting a 2k video signal to a 4k video signal.
