LCD-TFT (LTDC) display controller description

Example of a typical LTDC display frame

The Figure 13 shows an example of a typical LTDC display frame showing the timing

parameters described in Table 6.

Figure 13. Typical LTDC display frame (active width = 480 pixels)

LTDC flexible timings

The LTDC peripheral allows the user to interface with any display size with total width of up

to 4096 pixels and total height of up to 2048 lines (refer to Table 6).

Figure 14 illustrates fully programmable timings and resolutions.

LTDC_TWCR

TOTALW[11:0]

HSYNC width + HBP + active width + HFP - 1

From 1 to 4096 pixels

TOTALH[10:0]

VSYNC height + BVBP + active height + VFP - 1

From 1 to 2048 lines

1. Setting HSYNC to 0 in HSW[11:0] gives one pulse width of one LCD_CLK. Setting VSYNC to 0 in VSW[11:0] gives one

total line period
