i i i l l l l l l u u u m m m i i i n n n a a a n n n t t t I2421-7IBN2432B 8/14 notes : 1. contrast ratio(cr) is defined mathematically as : surface luminance with all wh ite pixels contrast ratio = ------------------------------- --------------------------------------------- surface luminance with all bl ack pixels 2. surface luminance is the center point across the lcd surface 500mm from the surface with all pixels displaying white. for more information see fig 1. 3. response time is the time required for the displ ay to transition from to black(rise time, tr r ) and from black to white(decay time, tr d ). for additional information see fig 3. 4. 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 more informa tion see fig 5. 5. optimum contrast is obtained by adjusting the lc d threshold voltage(vth & vsat) fig. 1 optical characteristic measurement equipment and method lcd cell optical stage(x,y) field = 2 bm-7 500 mm free datasheet http:///
