摘　　要：目前市场上需搭配LVDS屏幕的工业整机不能快速适配不同分辨率的屏幕,并且不同规格的LVDS屏幕,在使用Flash存储显示时序参数时,若需在一块主板上接不同的LVDS屏幕,均需要独立适配屏幕才能够正常显示。针对上述问题,提出一种在BIOS中嵌入PTN3460模块适配屏幕的方法,对于采用PTN3460的转接方案的显示屏,不再需要在线烧录对应屏幕分辨率专用的PTN3460固件,提高了调试效率,节约售后维护成本。Currently,industrial machines on the market that need to be paired with LVDS screens cannot quickly adapt to screens with various resolutions.Additionally,when using flash storage to display timing parameters with different specifications of LVDS screens,independent adaptation of the screen is required to display normally when different LVDS screens are connected to the same motherboard.To address these issues,this paper provides a method to embed the PTN3460 module in the BIOS to adapt the screen.For displays using the PTN3460 conversion scheme,there is no longer a need to burn a special PTN3460 firmware for the corresponding screen resolution online,which improves debugging efficiency and saves after-sales maintenance costs.
