For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of high-resolution LCD TV display circuit of compatible 1080P resolution, comprise master control borad and liquid crystal display socket, described master control borad is provided with a processor GM1601, the output terminal of described processor GM1601 comprises strange pixel and dual pixel two-way LVDS VT, 5 pairs of differential signal outputs are divided on each road again, comprise 4 pairs of data-signals and 1 pair of clock signal, two-way LVDS VT and one road gating end link to each other with the liquid crystal display socket, and then realization is connected with the liquid crystal display of 1080P resolution.
As further qualification to technique scheme, wherein one road LVDS VT of described processor GM1601 connects another road liquid crystal display socket, and then realization and being connected that common liquid crystals is shielded, in the utility model, strange pixel LVDS VT is connected described socket, the LVDS vision signal gating end of described socket connects a direct current power supply through a resistance, and Enable Pin connects described direct supply through another resistance.
Compared with prior art, advantage of the present utility model and good effect are: the utility model provides a kind of high-resolution liquid crystal display display circuit that can compatible 1080P resolution on the basis of available circuit, do not increasing the function expansion that has realized the 1080P product under the condition of cost, the not only compatible output format requirement of existing signal, and be that day by day ripe 1080P signal format has been done sufficient preparation, reached full HD demonstration truly, save the time for the exploitation of follow-up LCD TV product, improved reliability of products and compatibility.
Description of drawings
Fig. 1 is the schematic diagram of the high-resolution LCD TV display circuit of compatible 1080P resolution in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
The utility model is in order to realize full HD demonstration truly, 37 cun liquid crystal displays have been adopted with 1080P resolution, main control chip adopts the GM1601 chip of GENESIS company, this chip can single pixel be exported under the control of built-in with CPU, also can export by the double image element, can select arbitrarily by being provided with of internal register, promptly support two-way LVDS output mode.On the basis of available circuit, do not increase any circuit cost like this, liquid crystal display that simultaneously can compatible 1080P resolution shows, specifically describes below in conjunction with the hardware annexation of 1 pair of display circuit of accompanying drawing.
Among Fig. 1, the LVDS vision signal of processor GM1601 output is divided A, the output of B two-way, promptly strange, the output of dual pixel two-way, wherein, A is strange pixel output, B is dual pixel output, and 5 pairs of differential signal outputs, i.e. A road: TXA0-/TXA0+, TXA1-/TXA1+, TXA2-/XA2+, TXA3-/TXA3+, TXAC-/TXAC+ are divided in each road; B road: TXB0-/TXB0+, TXB1-/TXB1+, TXB2-/TXB2+, TXB3-/TXB3+, TXBC-/TXBC+.Wherein, TXA0~TXA3 and TXB0~TXB3 are the video data signal of processor GM1601 output, TXAC and TXBC are the video clock signal of processor GM1601 output, and strange pixel output terminal DORED5~DORED8, DOGRN3~DOGRN8 and dual pixel output terminal DEGRN6~DEGRN9, the DEBLU3~DEBLU9 by processor GM1601 exports respectively.If the liquid crystal display of single pixel, promptly now generally at the non-1080P liquid crystal display of usefulness, as long as 1 tunnel output, perhaps strange pixel or dual pixel specifically can be provided with by the register of processor GM1601 inside; If the liquid crystal display of double image element, promptly the liquid crystal display of 1080P resolution needs odd even two-way pixel to export simultaneously.Among Fig. 1, socket XP007 is single pixel accessory power outlet, connect general now non-1080P liquid crystal display in usefulness, its video data signal receiving end RA+, RA-, RB+, RB-, RC+, RC-, RD+, RD-and clock end RCLK+, RCLK-be the A road output of connection processing device GM1601 respectively, gating end LVDS_SEL is through resistance R 129 connection+3.3V direct supplys, Enable Pin AI_EN is through resistance R 209 connection+3.3V direct supplys, VBR_OUT links to each other with processor GM1601 with VBR_EXT, controls the backlight of liquid crystal display.When only exporting strange pixel video signal, the DEBLU9 of processor GM1601 end uses as I/O, to liquid crystal display output high-low level control signal, controls common liquid crystals jointly with other control signal and shields normal output video image.
