Problems solved by technology

[0003] In the development of flat-panel TVs, the core board is the core part of flat-panel TVs, and it is particularly important to improve its development speed and quality. There are still differences in the specification information and communication protocols of the LCD screens of different manufacturers. Therefore, the output display of the upper screen signal during the development of the movement needs to be constantly equipped with new platforms, which not only wastes development time, but also is not conducive to saving resources.
[0004] The current upper screen signal conversion scheme is to convert LVDS signal through V-by-One, and then convert LVDS signal to HDMI signal output. In this scheme, 2lane V-by-One signal input and 8laneV-by-One at the movement end There is a difference in the output standard signal format, which makes it impossible to directly process the signal. Therefore, it is necessary to modify the screen parameters to convert the 8lane signal output by the core end into a 2lane signal before further processing, and the converted upper screen signal is processed after the next level. Distortion is easy to exist when displaying, which is easy to mislead the subjective judgment and debugging of the image quality in the early stage of development

Abstract

The invention discloses a universal switching panel for V-by-One to HDMI output display of a liquid crystal television. The universal switching panel comprises a V-by-One and LVDS signal interface module, a V-by-One and LVDS signal compatible module, a V-by-One to HDMI output module and an HDMI signal output module; the V-by-One and LVDS signal interface module outputs an obtained signal; the V-by-One and LVDS signal compatible module converts a received signal into an 8lane V-by-One signal and outputs the 8lane V-by-One signal; the V-by-One to HDMI output module converts the received signal into an HDMI signal and outputs the HDMI signal; and the HDMI signal output module transfers the received signal to a display module. The universal switching panel disclosed by the invention can be suitable for 8lane V-by-One and LVDS signal output of an existing machine core and an output signal is not subjected to compression processing and is not distorted.

Description

technical field [0001] The invention relates to the technical field of LCD TV display, in particular to a universal adapter board and system for converting V-by-One of LCD TV to HDMI output display. Background technique [0002] In recent years, due to the strong participation of Internet companies, the competition in the traditional flat-panel TV industry has become increasingly fierce. Under the condition of ensuring quality, how to quickly and effectively respond to market demand and develop new products to attract consumers is extremely critical. [0003] In the development of flat-panel TVs, the core board is the core part of flat-panel TVs, and it is particularly important to improve its development speed and quality. There are still differences in the specification information and communication protocols of the LCD screens of different manufacturers. Therefore, the output display of the upper screen signal during the development of the movement needs to be constantly ...
