Connect LVDS display

0 votes
Hello,
I am working with a imx6 dual lite board. I was using the kit's display that digi provides but I need to use a different display, but when I connect It to lvds connector It works but the image shows very dark.

this is The dtb configuration, I am using timing@1, I could change resolution and frequency but the image shows dark.
I read that It could be the backlight configuration but I dont know how to do that.
&ldb {
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <18>;

display-timings {
native-mode = <&g101evn010_1>;

/* Fusion 10" F10A-0102 */
hsd101pfw2_1: timing@0 {
clock-frequency = <45000000>;
hactive = <1024>;
vactive = <600>;
hfront-porch = <0>;
hback-porch = <0>;
hsync-len = <176>;
vback-porch = <0>;
vfront-porch = <0>;
vsync-len = <25>;
};

/* AUO G101EVN01.0 */
g101evn010_1: timing@1 {
clock-frequency = <68930000>;
hactive = <1280>;
vactive = <800>;
hfront-porch = <120>;
hback-porch = <0>;
hsync-len = <8>;
vback-porch = <10>;
vfront-porch = <0>;
vsync-len = <6>;
hsync-active = <1>;
vsync-active = <1>;
de-active = <1>;
pixelclk-active = <0>;
};
};
};

Check LCD HRMA and see how the brightness/backlight are controlled.

Perhaps you can do something similar:
lcd_bl: backlight {
compatible = "pwm-backlight";
pwms = <&ecap0 0 50000 0>;
brightness-levels = <0 51 53 56 62 75 101 152 255>;
default-brightness-level = <8>;
};
