Figure 31. TFT LCD interface timing overview1
3.20.3.1
Interface to TFT LCD panels—pixel level timings
Figure 32 depicts the horizontal timing (timing of one line), including both the horizontal sync pulse and data. All parameters
shown in the diagram are programmable. This timing diagram corresponds to positive polarity of the DCU_CLK signal
(meaning the data and sync signals change on the rising edge) and active-high polarity of the DCU_HSYNC, DCU_VSYNC
and DCU_DE signals. The user can select the polarity of the DCU_HSYNC and DCU_VSYNC signals via the SYN_POL
register, whether active-high or active-low. The default is active-high. The DCU_DE signal is always active-high.
Pixel clock inversion and a flexible programmable pixel clock delay are also supported. They are programmed via the DCU
Clock Confide Register (DCCR) in the system clock module.
The DELTA_X and DELTA_Y parameters are programmed via the DISP_SIZE register. The PW_H, BP_H and FP_H
parameters are programmed via the HSYN PARA register. The PW_V, BP_V and FP_V parameters are programmed via the
VSYN_PARA register.
1. In Figure 31, the “DCU_LD[23:0]” signal is an aggregation of the DCU’s RGB signals—DCU_R[0:7], DCU_G[0:7] and
DCU_B[0:7].
