DESCRIPTION
The SED1765 is an LCD driver for driving the segment side, gradations by the PWM (Pulse Width Modulation)
method. The SED1765 makes it possible to display gradations of dot matrix large MIM liquid crystal panel, and
is used with the SED1177 as common driver.
The adoption of the PWM method and control of pulse position have brought flicker-free high definition gradation
display. Also, this driver has 160 LCD output terminals of high driving voltage. For example, the SED1765 can
drive a gradation displaying liquid crystal panel of 640
×
480 dots with the SED1177 at 7 drivers.

FEATURES
q
Liquid crystal display in 16 gradations
• Gradation signal ..................................................... 4 bits x 2
• On-pulse positions can be set in 1H area, and pulse width modulations for centering and right justification can
be selected.
• Gamma compensation suitable for liquid crystal characteristics is easy.
• 4 gradations and 8 gradation can correspond to each other.
q
Number of LCD driving output terminals160
q
Operating frequency
• Max. 12 MHz (When the enable automatic transfer facility is used)
One screen driving method can apply to 640 x 480 dots.
• Max. 16 MHz (When the enable automatic transfer facility is not used)
q
Range of liquid crystal driving voltage +14 to +40 V
q
The inhibit function makes display blanking possible.
q
Selectable output shift direction.
q
The enable automatic transfer facility has realized cascade connection and power reduction. (Enable signals
need not be generated by controller.)

Note 3 : If the logic circuit power supply comes to float while voltage is applied to the
liquid crystal driving circuit, the LSI may be broken permanently. So, prevent
the logic circuit power supply from floating.
Pay special attention to the power supply sequence when the system is
switched on or off.
