Product Specification
LP121WX4
Liquid Crystal Display
Note)
1. Contrast Ratio(CR) is defined mathematically as
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
2. Surface luminance is the average of 5 point across the LCD surface 50cm from the surface with
all pixels displaying white. For more information see FIG 1.
LWH = Average(L1,L2, … L5)
3. The variation in surface luminance , The panel total variation (δ ) WHITE is determined by measuring LN
at each test position 1 through 13 and then defined as followed numerical formula.
For more information see FIG 2.
δ WHITE (%) =
Minimum(L1,L2, … Ln)
Maximum(L1,L2, … Ln)
× 100(%)
4. Response time is the time required for the display to transition from white to black (rise time, TrR) and
from black to white(Decay Time, TrD). For additional information see FIG 3.
5. 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 information see FIG 4.
