Preliminary TOSHIBA CMOS Digital Integrated Circuits Silicon Monolithic
JBT6K47-AS
Source Driver for TFT LCD Panels
The JBT6K47-AS is a 64 gray-level, 240-channel-output source driver for TFT LCD panels. 6-bit digital input
enable to display colors using internal DA converter and five external power supplies. Also, JBT6K47-AS
incorporates power saving function to control recognition of the grayscale data input. When display performance is
not necessary, such as in a portable device, JBT6K47-AS ignores the grayscale input data.
Based on high-speed CMOS, the JBT6K47-AS offers both low power consumption and high-speed operation.
Features
· Grayscale data: 18-bit digital (3 outputs × 6 bits) parallel transfer method, selectable write direction
· Panel drive outputs: 240 outputs
· Grayscale levels: Capable of switching 2-grayscale mode and 16 grayscale/64 grayscale mode, and capable of
reference analog voltage inputs.
· High-speed operation: 5 MHz (max)
· Display mode: Normal display mode
· Power supply voltage: Digital power supply voltage (DVDD) .............2.5 to 3.6 V
Analog power supply voltage (AVDD)..............4.5 to 5.6 V
· Operating temperature: 20 to 75°C
· Package: Gold bump chip
· CMOS process
· Cascading multiple devices

JBT6K47-AS
· Reference power supply circuit
The connection between the device and the reference power supply for reference analog voltage inputs
is configured with the resistors in series. The reference power supply circuit is capable of impedance
transforming the corrected voltage using the Op amp, and the voltage is used for the grayscale level
power supply of the internal circuit.

Note 4: When correction is needed, connect the correction resistor between VLC terminal and /VLC
terminal of JBT6K49-AS, and apply bias on V0 to V5 pins of JBT6K47-AS.
· Grayscale data and output voltages
The output voltage is determined by the grayscale data value and six reference analog voltage inputs
(V0 to V5). It equally divides g correction voltage using 6 bits grayscale data and converting D/A.
