Part Number: SN65DSI86

Hi TI,
We will use Qualcomm SM8250 platform to Bringup Samsung's EDP interface for OLED screens.
1. How do we control the screen brightness through AUX channel?
2. How do we configure registers?
3. Is there any application case you can provide for our reference?
4. The specifications of the screen are listed in the following link, please help to check, thank you!

Hello Chen,

1. Please see https://e2e.ti.com/support/interface-group/interface/f/interface-forum/948343/sn65dsi86-dsi86-ddc-communication-fail for support with brightness control.

2. For DSI86 use the spreadsheet in this e2e post, https://e2e.ti.com/support/interface-group/interface/f/interface-forum/945404/faq-sn65dsi86-how-do-i-programming-the-sn65dsi86-registers

Additionally, use the Programming Guide here:

https://www.ti.com/lit/an/slla425/slla425.pdf?ts=1662043990867&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FSN65DSI86

3. You can use the video tutorials for the other DSI8x devices (as reference) found here:

https://training.ti.com/configuring-sn65dsi8x-single-channel-dsi-single-link-lvds-operation

Additionally, please refer to the "9 Application and Implementation" of the DSI86 datasheet.

4. I can't find any problems using the display based on provided specs.

Thanks,

Zach

Hey Zach,

What refresh rate does sn65dsi86 support? And whether the dsc protocol of MIPI-DSI is supported?

Thanks!

Hello, Chen,

Refresh rate supported depends upon display resolution, bpp and data rate. For example, the DSI86 is suitable for 60 fps 4K 4096 × 2304 resolution at 18 bpp color, and WUXGA 1920 × 1200 resolution with 3D graphics at 60 fps (120 fps equivalent).

What is the DSC protocol? This device implements MIPI® D-PHY version 1.1 physical layer front-end and display serial interface (DSI) version 1.02.00. If this protocol is supported it would be referenced in the specifications from MIPI®.

Thanks,

Zach
