MIPI TFT display interface issue: Picture not displayed full screen

chiranjeevikinn — Mon, 15 Aug 2016 19:03:44 GMT

Hi All,

I am using MIPI TFT display from DLC which has HX8394 single chip driver on iMX6Solo.

The picture is not displayed full screen and also there is some lines at the time of bootup. Please find the source code, pictures and datasheets for your reference.

Please let me know if anyone has faced this kind of issue.

I am using the following configuration derived from the data sheet.

static struct fb_videomode truly_lcd_modedb[] = {

{

"TRULY-WVGA", 64, 640, 1136, 37037,

40, 40,

348, 13,

13, 40,

FB_SYNC_OE_LOW_ACT,

FB_VMODE_NONINTERLACED,

};

Thanks in advance.

Best Regards,

Chiru

Hello,

App note AN4182 (Different Display Configurations on the i.MX31 Linux PDK)

helps to clarify display parameters configuring. In particular, please refer to section

4.3.1.2 (Panel Configuration)

Have a great day,
Yuri
