10. Reference to Viewing angle:
LCD panel: The driving voltage for most all LCD panels is above 3.3V. It is necessary
to then add a "negative voltage" IC on the PCB of the module or to the customer's
motherboard to raise the voltage. A couple of NV generators is as follows:
C. Backlight:
Viewing Angle is the direction by which the display will look best. This is established
during the manufacturing process and can not be changed by rotating the polarizer.
Viewing direction is specified in terms of a clock position, such as 6:00 & 12:00.
Please refer to the following drawing:
KS0065 2.7 ~ 5.5V
KS0063 2.7 ~ 5.5V
SED1181 5.0V min.
NV IC: SCI7661 3X with temperature compensation.
SCI7660 2X, dice font available (at a much less expensive cost).
If a NV IC must be incorporated onto the module PCB, there is apt to be
two possible considerations:
1. Tooling cost
2. The PCB is too small to accommodate the NV IC. If there is not
sufficient space, a possible solution would be to replace one controller
with a driver, with single controller (such as replacing a KS0066(U) &
KS0065(B) with a KS0070). The per unit cost will be a little greater but it
will save overall space on the PCB and eliminate having to re-tool the
PCB.
Some TAB IC's such as SED1560 series include a power circuit, which
can amplify the input voltage to drive the LCD. In this case it is not
necessary to add a NV IC to raise the voltage.
CCFL & EL: These backlight options require an inverter. The inverter
chosen cannot exceed 3.3 Volts.
LED: In an attempt to achieve this 3.3V requirement it is necessary to
use an edge-lit LED. Note this edge-lit LED will still consume a large
current.
