Note 1: Ambient temperature = 25
℃
. Note
2: To be measured in dark room after backlight warm up 30 minutes. Note
3: To be measured with a viewing cone of 1
°
by Topcon luminance meter ELDIM
EZContrast 160D.
Note 4: To be measured with the detector PR880
Note 5: Definition of response time: The output signals of BM-7 are measured when the input
signals are changed from “Black” to “White” (falling time) and from “White” to “Black” (rising
time), respectively. The response time interval between the 10% and 90% of amplitudes. Refer
to figure as
The response time is defined as the following figure and shall be measured by switching the
input signal for “black” and “white”.
Note 6. Definition of contrast ratio: Contrast ratio is calculated with the following formula.
Contrast ratio (CR)= Brightness on the "white" state
--------------------------------------
Brightness on the "black" state
Note 7: Driving conditions for CCFL: IL= 6.5 mA, 52KHz Frequency.
