用了MQ-r的板子，接上LVDS屏幕
把LCD的引脚引出来，淘宝买了一个40Pin排线，把2.54mm针的距离引出来
然后查看原理图，查看board.dts，查看引脚，接上
由于LVDS屏幕需要一个正负电压，查看规格书，
VGH 18V，VGL -10V，手头没有，于是淘宝找了一个LVDS电压转接板，把负电压，正电压，升压得到合适的电压，下面是升级板
接上屏幕，另外一边接转接板。修改dts文件如下
&lcd0 {
lcd_used = <1>;
lcd_driver_name = "default_lcd";
lcd_if = <3>;
lcd_x = <1024>;
lcd_y = <600>;
lcd_width = <150>;
lcd_height = <94>;
lcd_dclk_freq = <51>;
lcd_pwm_used = <0>;
lcd_hbp = <80>;
lcd_ht = <1344>;
lcd_hspw = <20>;
lcd_vbp = <10>;
lcd_vt = <635>;
lcd_vspw = <10>;
lcd_lvds_if = <0>;
lcd_lvds_colordepth = <1>;
lcd_lvds_mode = <1>;
lcd_frm = <1>;
lcd_hv_clk_phase = <0>;
lcd_hv_sync_polarity= <0>;
lcd_gamma_en = <0>;
lcd_bright_curve_en = <0>;
lcd_cmap_en = <0>;
pinctrl-0 = <&lvds0_pins_a>;
pinctrl-1 = <&lvds0_pins_b>;
};
最后上电，成功点亮
完成，走了很多弯路，因为对LVDS不了解，淘宝买东西耽搁几天时间。大家可以对照着来，如果用到LVDS的话。
