18.5 i.MX53 Display Interface Helpful Information
TFT panels are handled by the i.MX53 IPU legacy interface, which enables the display port to use different
types of display interfaces that conform to the following features and restrictions.
• The IPU supports four displays in total.
• The display port has two DI interfaces.
• Each interface can handle up to three displays.
• Each DI can handle up to two asynchronous interfaces (e.g. Smart LCD, Graphic accelerator).
• Only one asynchronous interface per DI can be serial.
• Each DI can handle one synchronous interface (e.g. TV, dumb LCD).
• Asynchronous displays that are accessed in synchronous mode are considered a synchronous
interface (dual_mode).
Each DI in the i.MX53 can handle one synchronous (dumb display).
Figure 18-4 shows an example i.MX53 board display interface layout.
