Abstract

The invention discloses a signal conversion method and device. According to the method, image data partition processing and field frequency multiplication processing are carried out on a low voltage differential signaling (LVDS) with low resolution and brush frequency output from a traditional image signal source to generate a signal applicable to dot screen test of a V-BY-ONE display module, and thus, the purpose of lighting the V-BY-ONE display modules with resolution of 4k, 8k and 10k, various different display Lane numbers and display screen modes by the existing image signal source is achieved. The device provided by the invention can be used for receiving external configuration through an upper-layer interface module, can be applicable to the V-BY-ONE modules with different resolutions, also can be suitable for the LVDS image signals input from various traditional image signal sources, and has the advantages of simplicity and convenience in operation; on the other hand, the device can be implemented by a field programmable gate array (FPGA) chip, and the technical scheme is flexible; and moreover, the device has the characteristics of relatively low cost and stable working performance.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and more specifically relates to a signal conversion method and device for lighting a super-high-resolution V-BY-ONE display module by using a low-resolution image signal source. Background technique [0002] With the development of liquid crystal display technology, large-size display devices with ultra-high-definition 4K resolution (3840×2160) (display area greater than 50 inches) have become popular, and large-size display devices with ultra-high-definition 8K resolution (7680×4320) have also become popular. Start mass production. In order to achieve ultra-high resolution display performance, ensure the reliability of use, and reduce manufacturing costs, these display device modules mostly use V-BY-ONE video interface technology to receive image signals. [0003] The V-BY-ONE display module is mainly tested by displaying static images. Since many manufacturers are shifting from ord...
