DATA SHEET

MOS INTEGRATED CIRCUIT

µ PD16770

420-OUTPUT TFT-LCD SOURCE DRIVER

(COMPATIBLE WITH 64-GRAY SCALES)

DESCRIPTION

The µ PD16770 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 V^SS2+ 0.1 V to V^DD2– 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

• Logic power supply voltage (V^DD1): 2.3 to 3.6 V

• Driver power supply voltage (V^DD2): 8.5 V ± 0.5 V

• High-speed data transfer: f^CLK= 45 MHz (internal data transfer speed when operating at V^DD1= 2.3 V)

• Output dynamic range V^SS2+ 0.1 V to V^DD2– 0.1 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)

• Current consumption control function (LPC, HPC, Bcont)

• Slim chip
