Hi All,

I am trying to implement this display to be recognized under the panel-simple.c implementation in Linux.

(https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/panel/panel-simple.c)

Here is the relevant section that I am adding to panel-simple.c

static const struct display_timing displaytech_dt070btft_timing = { .pixelclock = { 45000000, 51200000, 57000000 }, .hactive = { 1024, 1024, 1024 }, .hfront_porch = { 160, 160, 160 }, .hback_porch = { 160, 160, 160 }, .hsync_len = { 20, 20, 20 }, .vactive = { 600, 600, 600 }, .vfront_porch = { 12, 12, 12 }, .vback_porch = { 23, 23, 23 }, .vsync_len = { 3, 3,... (More)

The difference between the two back lights is that one is made up of 21 LEDs (7 rows of 3) and the other is made up of 30 LEDs (10 rows of 3).

To see a difference in the brightness of the backlight between the standard and high-bright displays you will have to apply more overall current to the high bright.

If you are driving the LEDs with 190mA in both instances you will not see a difference in the brightness between the two because you are simply distributing the same overall current over more LEDs (i.e. at 190mA you... (More)

Use the following settings for yocto linux device for the DT070BTFT:

Display Settings

static const struct fb_videomode custom_mode = { /* 1024x600 @ 60 Hz, 31.5 kHz hsync */ NULL, 60, 1024, 600, 19512, 140, 160, 20, 12, 20, 3, 3, FB_VMODE_NONINTERLACED | FB_VMODE_ASPECT_16_9, FB_MODE_IS_VESA, };

For board design, be sure to use the following LVDS layout recommendations for IMX6 from the IMX6DQ6SDLHDG.pdf

• Follow standard high-speed differential routing rules for signal integrity.
• Each differential pair should be length matched to ± 5 mils.
• LVDS differential pairs should have a differential impedance of 100 ohm
• Note that there are no pad... (More)
