9.11.2 Tearing Effect Line Timings
The Tearing Effect signal is described below:
Table 9.11.1 AC characteristics of Tearing Effect Signal Idle Mode Off (Frame Rate = 60 Hz, Ta=25°C)
Symbol Parameter min max unit description
tvdl Vertical Timing Low Duration 13 - ms
tvdh Vertical Timing High Duration 1000 - µs
thdl Horizontal Timing Low Duration 33 - µs
thdh Horizontal Timing Low Duration 25 500 µs
Note: The timings in Table 9.10.1 apply when MADCTL ML=0 and ML=1
The signal’s rise and fall times (tf, tr) are stipulated to be equal to or less than 15ns.
The Tearing Effect Output Line is fed back to the MPU and should be used as shown below to avoid Tearing Effect:
