the sed1190 is a dot matrix lcd common (row) driver for driving high-capacity lcd panel at duty cycles
higher than 1/64. the lsi uses two serially connected, 32-bit shift registers to hold the display data, and level
shifter converts the ttl level 64-bit parallel data from the shift registers to levels suitable for use by the lcd
drive circuitry. the sed1190 generates common drive signals using the voltages supplied to lcd drive
voltages pins.
the sed1190 is used in conjunction with the sed1180 (64-bit row driver) to drive a large capacity dot matrix
lcd panel.
the sed1600 is a dot matrix lcd segment (column) driver for driving a high-capacity lcd panel at duty
cycles higher than 1/100 (up to 1/300). the lsi has a wide range of lcd driving voltages. due to the
architecture of the sed1600, the lcd driving voltage, v0, is isolated from the vdd supply. this provides the
ability to adjust the offset bias independently of vdd. these unique features allow the sed1600 to interface
with a variety of lcd panels. the sed1600 does not require a controller to output an enable signal to
implement daisy chain technology. this provides for easy interfacing with the lcd controllers such as the
sed1330, sed1351, sed1335, or the sed1341.
the sed1600 is used in conjunction with the sed1610 (86-row driver), sed1630 (68-bit row driver),
sed1631 (100-row driver), sed1632 (86-bit row driver), sed1633 (100-bit row driver), and sed1634 (100-
bit driver) to drive a large-capacity dot matrix lcd panel.
