[Note 1]Definitions of viewing angle range :
[Note 2]Definition of contrast ratio :
[Note 3]Definition of response time
[Note 4] This shall be measured at center of the screen.
[Note 5] This value is valid when O/S driving is used at typical input time value.
The response time (τd and τr) is defined as the following figure and shall be measured by switching the
input signal for “any level of gray (0%, 25%, 50%, 75% and 100%)” and “any level of gray (0%, 25%, 50%,
75% and 100%)”.
The contrast ratio is defined as the following.
t*:x-y...response time from level of gray(x) to level of gray(y)
τr = Σ(tr:x-y)/10 , τd = Σ(td:x-y)/10
