But that doesn't necessarily mean that this will solve your current problem. >> I've run into an issue with my uboot, I want to display a bitmap >> image when the system boots; however, all the screen does at startup is >> fade from white to black and back until the OS boots up. The TFT Displays I've seen fade slowly their colors and settle with some line or block artefacts or flash when they are not clocked properly. If you let them that way for some time (several hours) the liquid crystal stuff gets polarized (or whatever effect that is) and the stripes will stay forever. Check that the clocking fits to the datasheet. > ----------------------------------------- > Notice: This e-mail is intended solely for use of the individual > [...] Remove that crap, when posting to public lists.
