摘要
Abstract
The video driver circuit design of a high-performance LCD head mounted display(HMD)is introduced in this paper. The high-resolution DVI video signal decoding,video image processing and LCD drive functions were achieved by the cir-cuit. FPGA is taken as the hardware platform for video image processing,contrast/brightness adjustment,image scanning direc-tion control,LCD drive time-sequence generation and MINI-LVDS interface realization and so on. An ASIC is adopted to pro-duce Gamma voltage LCD needs to drive 0.96-inch LCD screen. It has the characteristics of high-resolution display (1 400 × 1 050),parameter adjustability,simple interface,low-power consumption,etc. The reliability of the circuit functions were verified by physical testing.关键词
