Gray to Gray Response Time Uniformity
This is only the reference data of G to G and uniformity for LC470EUF-SDA1 model.
1. G to G Response Time :
Response time is defined as Figure3 and shall be measured by switching the input signal for
“Gray (N) ” and “Gray(M)”.(32Gray Step at 8bit)
2. G to G Uniformity
The variation of G to G Uniformity , δ G to G is defined as :
Maximum(GtoG) −Typical(GtoG)
≤1
G to G Uniformity =
Typical(GtoG)
*Maximum (GtoG) means maximum value of measured time (N, M = 0 (Black) ~ 1023(White), 128 gray step).
