23 / 91 page ![]() DocID029237 Rev 2 23/91 AN4861 LCD-TFT (LTDC) display controller description 89 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 Table 6. LTDC timing registers (continued) Register Timing parameter Value to be programmed |
