JBT6L78-AS
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
JBT6L78–AS
Gate Driver for TFT LCD Panel
The JBT6L78-AS is a 162-channel output gate driver for TFT LCD panels. This device accepts external input of
the panel drive voltage, allowing you to change the low-level output voltage. Thus, the can be used for various TFT
LCD panel drive systems.
The JBT6L78-AS offers high integration circuit due to CMOS technology.

JBT6L78-AS
Pin Description
Pin Name
I/O
Function
Vertical shift data input/output pins
Input/output shift data. The pin function is switched between input and output by the U/D pin as
follows:
U/D
DI/O
I/O
DO/I
DI/O
DO/I
H
Input
Output
L
Output
Input
At input
Data are latched into the shift registers in sync with the rising edge of CPV.
At output:
If the JBT6L78-AS is cascade-connected, data to be input at the next stage are output from the
pin. The data state changes in sync with the falling edge of CPV.
U/D
I
Data transfer direction switching pin
Specifies the shift direction of the shift registers.
Data in the shift registers shift in sync with the rising edge of CPV as follows:
· U/D = H: G1 ® G2® G3 ® … ® G162
· U/D = L: G162 ® G161® G160 ® … ® G1
Use the pin at DC level. For High, VDD; for Low, VSS.
Note that if U/D mode is switched during data transfer, misoperation occurs to a display page.
CPV
I
Vertical shift clock
Shift clock for the shift registers. Data are shifted in sync with the rising edge of CPV.
OE1 to OE3
I
Output enable pin
These pins control output data from the output pins (G1 to G162).
· OE = L: Normal output state (1-pulse scanning)
· OE = H: Outputs VOFF voltage.
Note that the contents of the shift registers are not cleared. Those operations are performed
asynchronously to CPV.
G1 to G162
O
LCD panel drive pins.
I
TEG
Test pin.
Leave the pin open.
VGG
Power supply pin for controlling LCD.
VOFF
LCD off level input pin
VDD
Power supply pin for internal logic
VSS
Power supply pin for cascade output
VCC
Power supply pin for LCD control and internal logic
VEE
Power supply pin for controlling LCD

RESTRICTIONS ON PRODUCT USE
000707EBM
· TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor
devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical
stress. It is the responsibility of the buyer, when utilizing TOSHIBA products, to comply with the standards of
safety in making a safe design for the entire system, and to avoid situations in which a malfunction or failure of
such TOSHIBA products could cause loss of human life, bodily injury or damage to property.
In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as
set forth in the most recent TOSHIBA products specifications. Also, please keep in mind the precautions and
conditions set forth in the “Handling Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability
Handbook” etc..
· The TOSHIBA products listed in this document are intended for usage in general electronics applications
(computer, personal equipment, office equipment, measuring equipment, industrial robotics, domestic appliances,
etc.). These TOSHIBA products are neither intended nor warranted for usage in equipment that requires
extraordinarily high quality and/or reliability or a malfunction or failure of which may cause loss of human life or
bodily injury (“Unintended Usage”). Unintended Usage include atomic energy control instruments, airplane or
spaceship instruments, transportation instruments, traffic signal instruments, combustion control instruments,
medical instruments, all types of safety devices, etc.. Unintended Usage of TOSHIBA products listed in this
document shall be made at the customer’s own risk.
· Light striking a semiconductor device generates electromotive force due to photoelectric effects. In some cases
this can cause the device to malfunction.
This is especially true for devices in which the surface (back), or side of the chip is exposed. When designing
circuits, make sure that devices are protected against incident light from external sources. Exposure to light both
during regular operation and during inspection must be taken into account.
· The products described in this document are subject to the foreign exchange and foreign trade laws.
· The information contained herein is presented only as a guide for the applications of our products. No
responsibility is assumed by TOSHIBA CORPORATION for any infringements of intellectual property or other
rights of the third parties which may result from its use. No license is granted by implication or otherwise under
any intellectual property or other rights of TOSHIBA CORPORATION or others.
