384-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64-GRAY SCALES)
DESCRIPTION
The µ PD16716 is a source driver for TFT-LCDs capable of dealing with displays with 64-gray scales. Data input
is based on digital input configured as 6 bits by 6 dots (2 pixels), which can realize a full-color display of 260,000
colors by output of 64 values γ -corrected by an internal D/A converter and 5-by-2 external power modules. Because
the output dynamic range is as large as VSS2 + 0.1 V to VDD2 – 0.1 V, level inversion operation of the LCD’s common
electrode is rendered unnecessary. Also, to be able to deal with dot-line inversion, n-line inversion and column line
inversion when mounted on a single side, this source driver is equipped with a built-in 6-bit D/A converter circuit
whose odd output pins and even output pins respectively output gray scale voltages of differing polarity. Assuring a
maximum clock frequency of 70 MHz when driving at 3.0 V, 45 MHz when driving at 2.5 V, this driver is applicable to
XGA/SXGA-standard TFT-LCD panels.
FEATURES
• CMOS level input (2.5 to 3.6 V)
• 384 Outputs
• Input of 6 bits (gray scale data) by 6 dots
• Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter (R-
DAC)
• Logic power supply voltage (VDD1) : 2.5 to 3.6 V
• Driver power supply voltage (VDD2) : 15.0 V ± 0.5 V
• Output dynamic range VSS2 + 0.1 V to VDD2 – 0.1 V
• High-speed data transfer: fCLK = 70 MHz (internal data transfer speed when operating at VDD1 = 3.0 V),
45 MHz (internal data transfer speed when operating at VDD1 = 2.5 V)
• Apply for dot-line inversion, n-line inversion and column line inversion
• Output Voltage polarity inversion function (POL)
• Display data inversion function (capable of controlling by each input port) (POL21, POL22)
• Low power control function (LPC)
