The invention discloses a device and method for generating a slash movement graph signal based on an FPGA. An image slash movement module and an image slash movement control module are integrated in an on-site programmable gate array. An image storage interface serves as an image input end of the on-site programmable gate array, and a slash movement image output interface serves as an image output end of the on-site programmable gate array. A signal input end of the image slash movement control module serves as a control signal input end of the on-site programmable gate array, and the image storage interface is connected with a signal input end of the image slash movement module. A signal output end of the image slash movement module is connected with a slash movement image output interface, and an image slash movement control signal output end of the image slash movement control module is connected with the image storage interface and a control signal input end of the image slash movement module. The image storage interface is used for receiving original stationary image data. The device can carry out the display of a slash movement effect, and can configure the movement speed and time from the upper layer.
Description
technical field [0001] The present invention relates to the technical field of display and testing of liquid crystal modules, in particular to a device and method for generating oblique moving graphic signals based on FPGA (Field-Programmable Gate Array, ie field programmable gate array). technical background [0002] With the development of liquid crystal display devices, the display effect is becoming clearer and more realistic. Therefore, many display products are not only used for common pictures and text display, but also widely used by people for watching movies, games and other programs. In order to meet the needs of consumers and gain a favorable position in the market competition, more and more display device manufacturers are now paying more and more attention to the display effect of display modules under dynamic screens or screen changes, and invest a lot of cost in related research. [0003] During R&D, production, and debugging, these manufacturers need the ima...
