Hello!
The Mallow Carrier Board, when paired with the Verdin AM62, supports LVDS display output through a DSI-to-LVDS bridge configuration. Here’s a concise overview:
-
DSI-to-LVDS Bridge Configuration:
- The Texas Instruments SN65DSI84-Q1 DSI to LVDS bridge can be set up for dual-channel LVDS output, supporting resolutions up to 1080p60 with 24-bit color in dual-channel mode. You can find more details in the Toradex documentation.
-
LVDS Interface Layout Requirements:
- Ensure proper length matching between the clock pair and data signals.
- The maximum frequency is contingent on the display resolution, with the frequency being seven times higher than the pixel clock in single-channel mode.
- Maintain a trace impedance of 100Ω ±15% differential and 55Ω ±15% single-ended.
-
Connectivity Considerations:
- The DSI to LVDS bridge requires configuration via I2C.
- Use the PWM_3_DSI pin (19) for display brightness control.
- The I2S_2_D_OUT can be utilized for enabling the display backlight.
Setting Up Dual-Channel LVDS:
-
Hardware Setup:
- Connect your display to the LVDS Display Connector (X12).
- Ensure JP1 is configured correctly for backlight power.
- If using touch functionality, connect the touch interface to X13. More information can be found in the Toradex community discussion.
-
Software Configuration:
- Apply the appropriate device tree overlay for your specific display configuration. For instance, a 10.1" LVDS display might use an overlay like “verdin-am62_panel-cap-touch-10inch-lvds_overlay.dtbo.”
I recommend reviewing the specific requirements of your LVDS display panel to ensure compatibility with these specifications.
