Embodiment
The utility model reaches through following measure, illustrates with the LED LCD TV:
At first, single transmission means in the past is as shown in Figure 1, and DVD player AV signal outputs signal to radiating portion, again receiving unit is exported the AV signal and shows for the liquid crystal television set.The utility model scheme is shown in Fig. 2 system block diagram, and AV process chip MST6M48 (stars semiconductor) and transmitter module are formed radiating portion, and receiving unit is made up of receiver module and LCDs.Because the MST6M48 chip can be handled the polytype input interface, such as, AV, TV, USB, YPbPr, PC, HDMI, interfaces such as network just can be realized various types of signal wireless transmission.
SecondlyShown in Fig. 3 system radiating portion; AV process chip MST6M48 output LVDS (supply liquid crystal display screen) differential signal rear end is increased signaling conversion circuit, and this differential signal change-over circuit chip is THC63LVD1023 (a THINE company), can convert the LVDS differential signal into the TTL signal; With on TTL signal modulation 5G transmitter module (this wireless transmitter module is the chip of the exploitation AMN3110+AMN2110 of the AMIMO company) circuit, again power supply is supplied with transmitter module confession+5V voltage again; Give+12V and+5V for that part of circuit of image processing MST6M48, thereby realize that picture signal launches between the wireless transmitter module.
At last, like Fig. 4, shown in system's receiving unit; 5G receiver module (AMN3210+AMN2210 of AMIMO company) receives wireless signal, demodulates the TTL signal, the LCDs standard configuration interface LVDS because the TTL signal does not match; To the TTL conversion of signals be become the LVDS signal; Through chip THC63LVD1024 (with THC63LVD1023 be the chip of corresponding conversion, THINE company) conversion, like this LVDS differential signal is directly supplied with the LVDS input interface of display screen.Power supply is directly supplied with receiver module+5V voltage, and+12V can be used for supplying with sound power amplifier and LCDs.So just can realize that liquid crystal partly plugs in, just can receive MST6M48 chip image processing signals, thereby realize operation and watch the program of any signal source.
