Planar High Brightness, High Contrast Display Setup and Hold Timing, Timing Characteristics

Table 4. Timing Characteristics.

Description	Min		Max	Unit	Note
T1 Vertical Front Porch	60			µs	1
T2 VS HIGH/LOW time	1			tVCLK	2
T3 Vertical Blank	40			µs
T4 Vertical Period	256			tHS
VS frequency		120		Hz
Description	Min		Typ	Unit	Note
T5 HS setup to VS	1			µs	3
T6 HS hold from VS	3			µs
T7 HS Low Time	4			tVCLK
T8 HS High Time	320	320		tVCLK	4
T9 HS period (tHS)	19			µs

Notes:

1.This time is needed to display the last row and to initiate the following frame.

2.Only rising edge is used.

3.2 tVCLK minimum

4.The number of VCLK pulses during HS high time must be even. Video clock VCLK must be kept running continuously.
