Graphics signal generation device and method based on fpga

Abstract

The invention relates to an FPGA-based figure signal producing device. The FPGA-based figure signal producing device comprises an upper layer interface module, an image parameter caching module, an image parameter conversion module, an external BMP interface module, a logic picture producing module, an image producing control module, an image storage control module, an RGB (red, green and blue) picture output module, an RGB picture timing sequence producing module and a multi-transmission-link low-voltage differential signal transmission module. The FPGA-based figure signal producing device can achieve a function of displaying logic pictures of BMP images and different patterns through an FPGA.

Description

technical field [0001] The invention relates to the technical field of display and testing of liquid crystal modules, in particular to an FPGA (Field-Programmable Gate Array, Field Programmable Gate Array)-based graphics signal generation device and method. Background technique [0002] As the resolution of liquid crystal display modules increases and the display effect becomes clearer and clearer, the technical requirements for the development, production, and testing of modules are also getting higher and higher. Therefore, in the detection of the module, it is necessary to detect the working status of each pixel of the module, and to detect the effect of the overall picture displayed by the module. In order to achieve these two goals, it is necessary to use different types of The former needs to display the logical picture (that is, the accurate and regular picture generated by the image signal source through its own calculation and processing), and the latter needs to di...
