Note: Do not display the fixed pattern for a long time because it may develop image sticking due to
the LCD structure. It should change pattern frequently. If the screen is displayed with fixed

Power On/Off Sequence
The HX8257-A has a power ON/OFF sequence control function. 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”).

Note 1: Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
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.

Definition of view angle (θ , φ ):
Figure 10
Note 4:
The above “Viewing Angle” is the measuring position with Largest Contrast Ratio; not for
good image quality. 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.
