Problems solved by technology

[0003] At present, the most widely used expansion method is to display multiple screens through an external VGA display, HDMI display, and DVI display. This method first has relatively high requirements for the graphics card, and must have an additional VGA, HDMI, or DVI interface. In addition, The external display connected through the external cable is separated, requires a separate power supply, a separate cable, and is not easy to carry, with poor flexibility and low reliability

Abstract

The invention discloses a three-screen display system and method for a domestic notebook. The system comprises an onboard display card used for generating an LVDS, an LVDS extending module used for extending the LVDS of the onboard display card into three signals, and a single-chip microcomputer module used for selectively controlling signal selection of the LVDS extending module to realize three-screen display. Compared with the prior art, the three-screen display system and method for the domestic notebook has the advantages that the reliability and flexibility of LVDS three-screen display can be effectively improved; the application of the three-screen display of the domestic autonomous notebook computer is realized; the utilization efficiency of LVDS resources is enhanced to the maximum extent; and the practicability is high.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a domestic notebook three-screen display system and method with strong practicability. Background technique [0002] With the continuous deepening of informatization construction, the country has gradually increased its emphasis on information security, especially in some important areas, independent controllability, security and credibility have become a consensus, so new requirements have been put forward for the construction of domestic independent platforms . In particular, the requirements for domestic notebook platforms are more diverse. In some special fields, multiple screens are required to be displayed at the same time. In order to control costs, facilitate portability, save space in the computer room, improve efficiency, and reduce energy consumption, an effective display extension method. A display technology that can realize three LVDS display screens at the same...
