9. Optical Characteristics
Optical characteristics are determined after the unit has been ‘ON’ and stable for
approximately 30 minutes in a dark environment at 25 °C. The values specified are at an
approximate distance 50cm from the TFT-LCD surface at a viewing angle of Φ and θ equal to 0°.
Measurement condition: Refer to next pages (LED back light with 20 mA/1 ea)
*1): with LGD Polarizer;
*2): Only Color Filter glass
Notes:
1. Contrast Ratio (CR) is defined mathematically as:
Contrast Ratio =
Surface Luminance with all white pixels
Surface Luminance with all black pixels
2. Surface luminance is the center point across the TFT-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 display to transition from white to black (Rise Time,
Tr) and from black to white (Falling Time, Tf). 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 TFT-LCD surface. For more information see FIG 5.
5. Optimum contrast is obtained by adjusting the TFT-LCD threshold voltage (Vth & Vsat).
