Problems solved by technology

But the disadvantage is that multiple signal conversions cause data distortion, and because this solution is a dedicated chip, it is not easy to promote, the compatibility is not good, and the cost is high
Furthermore, the solution cannot be achieved with only minor modifications to existing conventional displays

Abstract

The invention provides a display device, a display method and a computer. The display device comprises a liquid crystal display screen, a first LVDS signal module, a second LVDS signal module, a control module and an LVDS switch module, wherein the first LVDS signal module is used for converting an inputted narrowband signal to a first LVDS signal; the second LVDS signal module is used for converting an inputted wideband signal to a second LVDS signal; the control module is used for determining an LVDS signal to be outputted to the liquid crystal display screen finally and outputting a corresponding control command; and the LVDS switch module is used for outputting the determined LVDS signal to be outputted to the liquid crystal display screen finally according to the control command. Themethod comprises the following steps: converting the inputted narrowband signal to the first LVDS signal, and converting the inputted wideband signal to the second LVDS signal; and determining and outputting the LVDS signal to be outputted. The technical proposal adopted by the invention can realize the support to a DP signal of a novel digital interface for video and audio, and avoid the signal distortion at the same time.

Description

technical field [0001] The invention relates to the display field, in particular to a display device, a display method and a computer. Background technique [0002] DP (DisplayPort) is a new type of digital audio and video interface defined by the Video Electronics Association VESA, which is used to replace the traditional analog video interface Video Graphics Array (VGA, Video Graphic Array) interface, digital video interface (DVI, Digital Visual Interface), and High-definition multimedia interface (HDMI, High Definition Multimedia), its cost and bandwidth have advantages over the latter, and has increased the support for USB data transmission. Therefore, DP gradually began to be applied to display products. [0003] Existing traditional liquid crystal displays usually can only handle VGA, DVI, and / or HDMI input signal sources, and are only provided with VGA, DVI, and / or HDMI interfaces, and are not provided with DP interfaces capable of receiving DP signals. figure 1 It ...
