楼主
目前在RK3288板上调试SHARP 型号为lq150x1lg91 lvds屏，参照其规格书信息目前配置dtsi如下，现屏已能点亮能输出画面，但是画面上下两边会出现左右抖动图像扭曲变形，若这时RK3288板接上HDMI输出后屏的图像就恢复正常显示，盼大侠们指点迷津，谢谢！
屏规格书： http://media.digikey.com/pdf/Dat ... DFs/LQ150X1LG91.pdf
目前dtsi文件的配置如下：
/ {
disp_timings: display-timings {
native-mode = <&timing0>;
timing0: timing0 {
screen-type = <SCREEN_LVDS>;
lvds-format = <LVDS_8BIT_1>;
out-face = <OUT_D888_P666>;
clock-frequency = <65000000>;
hactive = <1024>;
vactive = <768>;
hback-porch = <0>;
hfront-porch = <320>;
vback-porch = <38>;
vfront-porch = <0>;
hsync-len = <20>;
vsync-len = <16>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <0>;
swap-rb = <0>;
swap-rg = <0>;
swap-gb = <0>;
};
};
};
