When DISP pin is pulled “H”, blank data is outputted for 10-frames first, from the falling edge of the following VSYNC signal. Similarly, when DISP is pulled “L”, 10-frames of blank data will be outputted from the falling edge of the following VSYNC, too. The blank data would be gray level 0 for normally black LC (NBW= “H”), and be gray level 255 for normally white LC (NBW= “L”).

Contrast Ratio (CR) = L63 / L0 L63: Luminance of gray level 63 L0: Luminance of gray level 0 CR = CR (5) CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note 5.

View Direction for good image quality is 6 O’clock. Measurement Set-Up: The LCD module should be stabilized at a given temperature for 20 minutes to avoid abrupt temperature change during measuring. In order to stabilize the luminance, the measurement should be executed after lighting Backlight for 20 minutes in a windless and dark room.
