面板是LG的 LD5500EUE 不管怎么调节 都是只有一多半的屏幕显示，而且关掉uboot LOGO后就黑屏了，什么都不显示了。
希望能在这里得到一些有用的信息，谢谢。
楼主最后点亮屏幕了么，可以交流一下不？

楼主最后点亮屏幕了么，可以交流一下不？
调节好了，还是初始化序列的原因，楼下有dts 楼主，请教一下，为什么用你提供的TC358775的配置数据，用示波器测量LVDS数据没有输出 楼主，这个LVDS在UBUNTU下面点亮过吗 文档都好难下载到啊,感谢分享. 为啥我的 LVDS VCC引脚电压一直为 0 啊，始终点不亮屏……………………郁闷啊………………！ 文档都好难下载到啊,感谢分享.
