I am using Colibri iMX7D 512MB(V1.1D) and trying to find a compatible 3.5’’ lcd tft display.
What are the criteria to look after in terms of resolution, interface type, driver ic, etc…?
Thanks and best regards,
Florian
Imx7 has an embedded LCD interface.
The enhanced Liquid Crystal Display Interface (eLCDIF) is a general purpose display
controller used to drive a wide range of display devices varying in size and capability.
The eLCDIF block supports the following:
• Displays with an asynchronous parallel MPU interface for command and data
transfer to an integrated frame buffer.
• Displays that support moving pictures and require the RGB interface mode
(DOTCLK interface).
• VSYNC mode for high-speed data transfers.
• Digital video encoders that accept ITU-R BT.656 format 4:2:2 YCbCr digital
component video and convert it to analog TV signals.
The eLCDIF provides fully programmable functionality to supported interfaces:
• Bus master interface to source frame buffer data for display refresh. This interface
can also be used to drive data for “Smart” displays.
• PIO interface to manage data transfers between “Smart” displays and SoC.
• 8/16/18/24/32 bit LCD data bus support available depending on I/O mux options.
• Programmable timing and parameters for MPU, VSYNC, and DOTCLK LCD
interfaces to support a wide variety of displays.
Please refer to the i.MX 7Dual Applications Processor Reference Manual for more details.
