LH1548
240-output LCD Segment Driver IC
LH1548
DESCRIPTION
PIN CONNECTIONS
The LH1548 is a 240-output segment driver IC
suitable for driving large/medium scale dot matrix
LCD panels, and is used in personal computers/
work stations. Through the use of UST (Ultra Slim
TCP) technology, it is ideal for substantially
decreasing the size of the frame section of the LCD
module. When combined with the LH1530 common
driver, it can create a low power consuming, highresolution LCD.

FUNCTIONAL OPERATIONS OF EACH BLOCK
BLOCK
Active Control
FUNCTION
Controls the selection or non-selection of the chip.
Following an LP signal input, and after the chip selection signal is input, a selection
signal is generated internally until 240 bits of data have been read in.
Once data input has been completed, a selection signal for cascade connection is
output, and the chip is non-selected.
SP Conversion &
Data is retained until 24 bits have been completely input, after which they are put on the
Data Control
internal data bus 24 bits at a time.
Selects the state of the data latch which reads in the data bus signals. The shift direction
Data Latch Control
Data Latch
is controlled by the control logic. For every 48 bits of data read in, the selection signal
shifts one bit based on the state of the control circuit.
Latches the data on the data bus. The latch state of each LCD drive output pin is
controlled by the control logic and the data latch control; 240 bits of data are read in 10
sets of 24 bits.
Line Latch
All 240 bits which have been read into the data latch are simultaneously latched at the
falling edge of the LP signal, and are output to the level shifter block.
Level Shifter
The logic voltage signal is level-shifted to the LCD drive voltage level, and is output to
the driver block.
4-Level Driver
Drives the LCD drive output pins from the latch data, and selects one of 4 levels (V0, V2,
V3 or V5) based on the FR and  signals.
Controls the operation of each block. When an LP signal has been input, all blocks are
Control Logic
reset and the control logic waits for the selection signal output from the active control
block. Once the selection signal has been output, operation of the data latch and data
transmission is controlled, 240 bits of data are read in, and the chip is non-selected.
Test Circuit
The circuit for testing. During normal operation, it isn't activated.

PRECAUTIONS
And when connecting the logic power supply, the
logic condition of this IC inside is insecure.
Therefore connect the LCD drive power supply
after resetting logic condition of this IC inside on
 function. After that, cancel the 
function after the LCD drive power supply has
become stable. Furthermore, when disconnecting
the power, set the LCD drive output pins to level V5
on  function. Then disconnect the logic
system power after disconnecting the LCD drive
power.
When connecting the power supply, follow the
recommended sequence shown here.
Precautions when connecting or disconnecting
the power supply
This IC has a high-voltage LCD driver, so it may be
permanently damaged by a high current which may
flow if voltage is supplied to the LCD drive power
supply while the logic system power supply is
floating. The details are as follows.
ø When connecting the power supply, connect the
LCD drive power after connecting the logic
system power. Furthermore, when disconnecting
the power, disconnect the logic system power
after disconnecting the LCD drive power.
ø It is advisable to connect the serial resistor (50 to
100 $) or fuse to the LCD drive power V0 of the
system as a current limiter. Set up a suitable
value of the resistor in consideration of the
display grade.
