Embodiment Construction

[0022] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] see figure 1 As shown, the new V-by-One interface ultra-high-definition image signal source device proposed by the present invention includes an ARM module, an FPGA module, an LVDS_TO_VBO module, a 16LANE V-by-One output module, a 4CH LVDS output module, and a DDR3 memory module. , SD card module, PS / 2 module, infrared receiving module, OLED module, RS232 module; when powered on, the ARM module reads the image content from the SD card module and loads it into the DDR3 memory module through the FPGA module, and then The image in the DDR3 memory module read by the FPGA module is output to the LVDS to V-by-One module through LVDS, and finally converted to V-by-One signal by the LVDS to V-by-One module and output to 16LANE V-by On the -One output module, after power-on, the ARM module receives the mouse command of...

Abstract

V-by-One interface ultra-high-definition image signal source, output 16LANE V-by-One signal, used to drive V-by-One interface ultra-high-definition LCD screen. After the signal source is powered on, the ARM reads the test pattern in the SD card and writes it to the DDR3 memory stick through the FPGA, and then ARM controls the FPGA to read the test pattern on the DDR3 memory stick and output it to the 16-channel LVDS signal. The LVDS to V‑by‑One chip THCV215 converts 16LANE V‑by‑One signals and outputs them to the V‑by‑One interface. The signal source has an RS232 communication interface, which can be used in the automatic test system of the LCD driver board.

Description

technical field [0001] The present invention relates to the liquid crystal screen driving technology in the field of liquid crystal television, specifically relate to a kind of ARM reads the image content from the SD card and loads it into the DDR3 memory stick through the FPGA, and then reads the image in the DDR3 memory stick by the FPGA and Output to the image signal generator on the V-by-One interface. Background technique [0002] In the past ten years, television technology has undergone unimaginable rapid development, analog display technology has been replaced by digital technology, the concept of full high-definition (FHD, 1920 x 1080 resolution) television has been deeply rooted in the hearts of the people, bringing users an unparalleled viewing experience Experience, with the full popularity of LCD flat-panel TVs, the screen size is increasing day by day, making the pixel density (PPI) continue to decline, full HD resolution can not meet the user's higher audio-vi...
