Device and method for generating vertically moving graphic signals based on fpga

Abstract

The invention discloses a device capable of generating vertically-moving graphic signals based on an FPGA (field-programmable gate array). The device is characterized in that an image vertical movement module and an image vertical movement control module are integrated in the field-programmable gate array, an image storage interface is the image input end of the field-programmable gate array and is connected with the signal input end of the image vertical movement control module, a vertically-moving image output interface is the image output end of the field-programmable gate array, and the signal input end of the image vertical movement control module is the control signal input end of the field-programmable gate array. The signal output end of the image vertical movement control module is connected with the vertically-moving image output interface, the image movement control signal output end of the image vertical movement control module is connected with the image storage interface and the control signal input end of the image vertical movement module, and the image storage interface is used for receiving original static image data. The device capable of generating the vertically-moving graphic signals based on the FPGA is capable of displaying movement effect and configuring movement speed and time of the signals by the upper layer.

Description

technical field [0001] The invention relates to the technical field of display and testing of liquid crystal modules, in particular to a device and method for generating vertically 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 image si...
