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
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 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)
Output dynamic range : V
SS2
+ 0.1 V to V
DD2
– 0.1 V
High-speed data transfer : f
CLK
= 45 MHz (internal data transfer speed when operating at V
DD1
= 2.3 V)
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)
Logic power supply voltage (V
DD1
) : 2.3 to 3.6 V
Driver power supply voltage (V
DD2
) : 8.5 V
