7Electro-Optical Characteristics
*Note 1: Definition of contrast ratio
Contrast Ratio (CR) is defined mathematically by the following formula.
CONTRAST RATIO = Luminance measured when LCD on the "White" State
Luminance measured when LCD on the "Black" State
*Note 2: Definition of surface luminance
Surface luminance is the LCD luminance from the surface with all pixels displaying white.
Lv = Average Surface Luminance with all white pixels (P1,P2,P3 …Pn)
*Note 3: Definition of luminance uniformity
The luminance uniformity in surface luminance (Yu) is determined by measuring luminance at each test position 1 through n,
and then dividing the maximum luminance of n point’s luminance by minimum luminance of n points luminance.
Yu = Minimum Surface Luminance with all white pixels (P1,P2,P3 …Pn)
Maximum Surface Luminance with all white pixels (P1,P2,P3 …Pn)
*Note 4: Definition of Response time
The response time is defined as the LCD optical switching time interval between “White” state and “Black” state. Rise time
(TON) is the time between photo detector output intensity changed from 90% to 10%. And fall time (TOFF) is the time
between photo detector output intensity changed from 10% to 90%.
*Note 5: Definition of color chromaticity (CIE1931)
CIE (x, y) chromaticity, the x, y value is determined by screen active area center position P5.
*Note 6: Definition of Viewing angle.
Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x
axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface.
For Viewing angle and response time testing, the testing data is based on Autronic-Melchers’s ConoScope or DMS series
Instruments or compatible. For contrast ratio, Surface Luminance, Luminance uniformity and CIE, the testing data is based on
TOPCON’s BM-7 or BM-5 photo detector or compatible.
*Note 7:For TFT module, Gray scale reverse occurs in the direction of panel viewing angle.
