Embodiment Construction
[0011] In order to facilitate those skilled in the art to understand the technical content of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0012] like figure 1 The vehicle display system processor generally includes a navigation processing unit and a graphics processing unit, and the LVDS sending chip is connected to it. The processor processes the information to be displayed into a digital RGB signal and transmits it to the LVDS sending chip through the bus. In the present invention, the processor simultaneously generates a low-frequency pulse signal, which occupies a lower data bit in the RGB signal (the lowest data bit B0 of the blue signal is selected in this embodiment), and is transmitted to the LVDS sending chip, and the LVDS sending chip will The received signal is modulated together and sent to the remote LVDS receiving chip.
[0013] After the remote LVDS recei...
