Currently, the video transmission function from a computer host to a display is mainly an analog VGA and a digital DVI or HDMI system; the display is powered by another independent system; therefore, when the display is installed and used, not only the heavy metal signal wire is connected with the computer host to obtain the video signal, but also an independent power supply system is separately provided; therefore, the installation and connection of the computer are complicated, and the internal device of the display is complicated; the computer use location is limited; the problems of high manufacturing cost and the like are highlighted; specifically shown are the following two aspects:
1. the transmission quality of signals is not guaranteed, and due to the characteristic of the metal wire, the signal wire cannot avoid a series of problems such as signal attenuation, limited length, signal interference and the like; in order to improve the quality performance, for example, to reduce the resistance, gold plating and silver plating are needed to be carried out on the surface of the metal wire, so that the contradiction between the production cost and the product quality is more and more prominent at the cost of consumption of a large amount of noble metals, and under the competitive environment of the current computer market, the transmission quality of video signals is greatly reduced due to continuous compression and even replacement of the noble metals; the proportion of such problems in the current after-market failure problem of displays is not lower than 30%; and the one-time resolution is very low; causing great damage to the brand of the product manufacturer.
2. The independent power supply of the display and the power supply in the computer host are repeatedly arranged at present, which causes unnecessary waste; does not meet the requirements of low carbon, environmental protection and high energy efficiency at present; the energy efficiency is low, and a series of problems of high product cost, large ineffective heat dissipation capacity, high failure rate, large radiation and the like are directly caused due to large quantity of used parts; the actual power supply requirements (12V, 5V and 3.3V direct current power supply) of the liquid crystal display can be directly provided by a host power supply, particularly, the rising of the current LED display backlight module (the backlight function can be realized only by low-voltage power supply) brings more convenience for the direct reference of the host power supply.
