As the utility model to the preferred of above scheme, the MIPI-HDMI conversion circuit converts core using LT9611
Piece, MIPI-LVDS conversion circuit use TC358775XBG conversion chip, to provide the display of multiplex roles by conversion circuit
Shield connection scheme.
Compared with the prior art, the utility model has the beneficial effects that: this kind of advertisement mainboard only passes through single mainboard
It can support LVDS, MIPI, HDMI, EP, DEP display interface of mainstream, there is extremely strong compatibility, MIPI and DP two major classes type
Signal, output type is switched by corresponding conversion switch respectively, according to the interface type of display screen, is switched to corresponding
Signal output interface carry out signal output, this structural support multiplex roles schemes, but be not by traditional LVDS, MIPI,
HDMI, EP, DEP interface simply add up, and each interface can not realize that signal exports simultaneously in the utility model, but pass through
Switching output, compared to cumulative multiplex roles structure, compatibility is more preferable, and cost is lower, and the utility model also avoids increase and turns
The cost of fishplate bar and artificial, also simple with assembling, the low advantage of assembly cost.This kind of advertisement mainboard, by supporting connect more
The function of mouth can be improved the adaptability for carrying the advertisement machine of this kind of mainboard, to meet the needs of different.
