8 / 18 page DMF-50174ZNB-FW (AT) No.2000-0166 OPTREX CORPORATION Page 8/18 OPTREX 3.Optical Specif ications 3.1.LCD Driving Voltage Parameter Symbol Conditions Min. Typ. Max. Units Recommended Ta= 0℃ - - 27.1 V LCD Driving Voltage VCC-VADJ Ta=25℃ 21.7 23.3 24.9 V Note 1 Ta=50℃ 19.9 - - V Note 1 : Voltage (Applied actual waveform to LCD Module) for the best contrast. The range of minimum and maximum shows tolerance of the operating voltage. The specified contrast ratio and response time are not guaranteed over the entire range. 3.2.Optical Characteristics Ta=25℃, 1/240 Duty, 1/14 Bias, VD=23.3V (Note 4), θ= 0 ゚, φ=-゚ Parameter Symbol Conditions Min. Typ. Max. Units Contrast Ratio Note 1 CR θ= 0 ゚, φ=-゚ - 4 - Viewing Angle Shown in 3.3 Response Rise Note 2 TON - - 100 200 ms Time Decay Note 3 TOFF - - 360 540 ms Note 1 : Contrast ratio is definded as follows. CR = LON / LOFF LON : Luminance of the ON segments LOFF : Luminance of the OFF segments Note 2 : The time that the luminance level reaches 90% of the saturation level from 0% when ON signal is applied. Note 3 : The time that the luminance level reaches 10% of the saturation level from 100% when OFF signal is applied. Note 4 : Definition of Driving Voltage VD VD=VCC-VADJ-VBE Assuming that the typical driving waveforms shown below are applied to the LCD Panel at 1/A Duty - 1/B Bias ( A : Duty Number, B : Bias Number ). Driving voltage VD is definded as the voltage VO-P when the contrast ratio (CR=LON / LOFF) is at its maximum. VO-P 1 / fF ( B-2 )×VO-P / B 1 / ( fF×A ) 〈OFF SIGNAL〉 〈ON SIGNAL〉 |
