Note 1: Definition of viewing angle
Viewing angle is the measurement of contrast ratioЊ10, or Њ5, at the screen center, over a 180 horizontal and
180 vertical range (off-normal viewing angles). The 180 viewing angle range is broken down as follows; 90 (Ӱ)
horizontal left and right and 90 (ӥ) vertical, high (up) and low (down). The measurement direction is typically
perpendicular to the display surface with the screen rotated about its center to develop the desired measurement
viewing angle.

Note 4: Measurement method
The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature change
during measuring. In order to stabilize the luminance, the measurement should be executed after lighting
Backlight for 30 minutes in a stable, windless and dark room. ʳ

Note 5: Definition of response time:
The output signals of photo detector are measured when the input signals are changed from “Full Black” to “Full
White” (rising time), and from “Full W hite” to “Full Black” (falling time), respectively. The response time is interval
between the 10% and 90% of amplitudes. Please refer to the figure as below.
