Brief description of the drawings
Fig. 1 is Tthe utility model system block diagram；
Fig. 2 is Tthe utility model system operating diagram.
Embodiment
The utility model is further elaborated with reference to embodiment of the present utility model.
Embodiment：
As shown in Figure 1 and Figure 2, the universe point screen device of LCD TV TCONLESS plates, it includes TV SOC (TV main cores
Piece), driving plate and PANEL (liquid crystal display), TCON built in the TV SOC, the TV SOC, which are produced, shields signal, the upper screen
Timing Control (timing control signal) in signal separate with data-signal.Selection Timing Control are linked into drive
P2P sockets on dynamic plate, the timing control signal of TCONLESS plates to be repaired output separate with DATA signal, select 12 groups
DATA signal is linked into the P2P sockets in driving plate.The Timing Control of TV SOC outputs match with liquid crystal display, to be repaired
TCONLESS plates export DATA signal, and driving liquid crystal display is shown under Timing Control effects.The Timing
Control includes the timing control signal of EPI data formats that LG is promoted mainly, the timing control signal of AUO ISP data form,
The timing control signal of the timing control signal of BOE CEDS data formats and the USIT data formats of Samsung.
The driving plate includes PMIC chips (power management integrated circuit chip), PGAMMA IC chips (programmable gamma
Correction buffer circuit chip), Level Shift circuits and P2P (Point to Point) socket.The TV master chip output
Control signal pass through Level Shift circuits, by level conversion produce driving liquid crystal display signal.PMIC chips pass through
