Hello everyone,

 

I have 15,6 inches dsplay which is running on DE mode. I made some modification in dtsi file.

Kernel version is 3.14.28.

 

My display is G156BGE - L01. It works single LVDS channel. I want to understand how to work this display with DE mode.

 

My dtsi file is here;. I added last 4 lines. After burn the image to my board, I had a view on the display but it is very dark. Backlight intensity is lower. How can i set this display? Please can you help me?

 

ldb {
    status = "okay";

 

    lvds-channel@0 {
        fsl,data-mapping = "spwg";
        fsl,data-width = <18>;
        primary;
        status = "okay";

 

        display-timings {
            native-mode = <&timing0>;
            timing0: hsd100pxn1 {
                clock-frequency = <96000000>;
                hactive = <1366>;
                vactive = <768>;
                hback-porch = <68>;
                hfront-porch = <44>;
                vback-porch = <13>;
                vfront-porch = <8>;
                hsync-len = <134 194 204>;
                vsync-len = <50 60 76>;

 

                de-active = <1>;
                hsync-active = <0>;
                vsync-active = <0>;
                pixelclk-active = <1>;
            };
        };
    };  

 

 

Thanks. Have a nice day.

Best regards.
