Problems solved by technology

However, this solution has great limitations. The processing capability and storage bandwidth of the sending card determine that it cannot process pixels in the entire range of video sources; and the receiving card usually receives pixel data that has been segmented. Part of the area, so even if the LED arbitrary point is supported, the point range is also very limited

Abstract

The invention provides a control device and a control method for an LED display screen capable of arbitrarily arranging pixels. The device includes: a decoding chip for decoding a video source signal into a TTL video signal; an encoding chip for converting VESA standard signals Encoded into differential signal; SRAM array, used to store TTL video signal; SPIFLASH, used to store address table; SDRAM, used to transfer address table; FPGA module, used to randomly read video pixels stored in SRAM array according to the address table Data; MCU, used to configure and monitor the encoding chip, decoding chip and FPGA module. The invention fully combines the high-bandwidth characteristics of SDRAM in continuous access and the high-bandwidth characteristics of SRAM in random access, and changes the output screen by issuing an address table through software to meet the display requirements of multi-scene changes.

Description

technical field [0001] The invention relates to the field of LED display screen control, in particular to an LED display screen control device and a control method capable of arbitrarily arranging pixels. Background technique [0002] LED display is a new type of information display medium, which is a flat display screen composed of light-emitting diode dot matrix blocks or pixel units. LED creative display has many styles: arc, circle, curved surface, tetrahedron, cross screen, letter, triangular screen, oval screen, etc. Its size and size are customized according to demand. [0003] Compared with conventional LED displays, LED creative displays are more inclined to users with special needs. Currently, they are mainly used in performing arts venues, outdoor media, exhibition halls, squares and other environments. Due to the different appearances and structures of LED creative displays, the technical requirements for manufacturers are also more stringent. [0004] The abno...
