Embodiment
Refer to Fig. 1, in a better embodiment of the present invention, a liquid crystal display comprises main body housing 10, liquid crystal board 11, drive plate 12, power panel 13, scaler 14, WiHD receiver 15, in vitro casing 20, multimedia board 21 and WiHD transmitter 22.Described liquid crystal display can receive and show the multi-media signal from video output device 30, and described video output device 30 can be televisor, host computer, DVD player etc.
Described liquid crystal board 11, described drive plate 12, described power panel 13 and described multimedia board 21 is the core component of an exemplary lcd.
Described multimedia board 21 provides multiple input and output (I/O) interface, such as USB interface, HDMI, component video interface, S terminal etc., and described video output device 30 is communicated with described multimedia board 21 by these interfaces.Described multimedia board 21 for from described video output device 30 multimedia signal receiving, such as vision signal.
Described WiHD transmitter 22 sets up wireless connections with described WiHD receiver 15, and the multi-media signal received from described video output device 30 is sent to described scaler 14 by described wireless connections by described multimedia board 21.WiHD is a wireless high-definition video host-host protocol operating in 60GHz frequency, is supported in wireless transmission high-definition video signal between multiple high definition device.
Described scaler 14 carries out convergent-divergent process for the multi-media signal received described WiHD receiver 15, described multi-media signal is converted to the multi-media signal adapted with the resolution of described liquid crystal board 11, then will sends to described drive plate 12 after the multi-media signal after convergent-divergent process.Such as, what export when described video output device 30 is the DVD vision signal of 500 lines, when the resolution of described liquid crystal board 11 is 1024x768 pixels, described scaler 14 improves the horizontal and vertical resolution of raw video signal, makes it be applicable to showing with the resolution of 1024x768 pixel.
Described drive singal for the multi-media signal received is converted to drive singal, and is sent to described liquid crystal board 11 by described drive plate 12.The multi-media signal sent here from described video output device 30 is data bus (Data Bus) signal, described liquid crystal board 11 can not Direct Recognition, so the drive singal needing described drive plate 12 described multi-media signal to be converted to described liquid crystal board 11 can to identify.
Under the ordering about of described drive singal, there is corresponding change in the Liquid Crystal Molecules Alignment in described liquid crystal board 11, thus produces corresponding image.
