DESCRIPTION

The

µ PD16772 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

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 UXGA-standard TFT-LCD panels.

FEATURES

• CMOS level input (2.3 to 3.6 V)

• 480 outputs

• Input of 6 bits (gradation 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)

• Apply for dot-line inversion, n-line inversion and column line inversion

• Output voltage polarity inversion function (POL)

• Display data inversion function (POL21/22)

• Current consumption reduction function (LPC, Bcont)
