420-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64-GRAY SCALE)
DESCRIPTION
The µ PD160062 is a source driver for TFT-LCDs capable of dealing with displays with 64-gray scale. 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 clock frequency of 45 MHz when driving at 2.3 V, this driver is applicable to SXGA+ standard TFT-LCD
panels.
FEATURES
• CMOS level input (2.3 to 3.6 V)
• 420 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) : 2.3 to 3.6 V
• Driver power supply voltage (VDD2) : 8.0 to 9.0 V
• High-speed data transfer: fCLK = 45 MHz (internal data transfer speed when operating at VDD1 = 2.3 V)
• Output dynamic range VSS2 +0.1 V to VDD2 –0.1 V
• Apply for dot-line inversion, n-line inversion and column line inversion
• Output voltage polarity inversion function (POL)
• Input data inversion function (capable of controlling by each input port) (POL21, POL22)
• Current consumption control function (LPC, HPC, Bcont)
• Slim chip
