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

Description
Input the γ -corrected power supplies from outside by using operational amplifier.
Make sure to maintain the following relationships. During the gray scale voltage
output, be sure to keep the gray scale level power supply at a constant level.
VDD2 −0.1 V ≥ V0 > V1 > V2 > V3 > V4 ≥ 0.5 VDD2
0.5 VDD2 ≥ V5 > V6 > V7 > V8 > V9 ≥ VSS2 +0.1 V
2.3 to 3.6 V
8.0 to 9.0 V
Grounding
Grounding
Cautions 1. The power start sequence must be VDD1, logic input, and VDD2 & V0 to V9 in that order. Reverse
this sequence to shut down.
2. To stabilize the supply voltage, please be sure to insert a 0.1 µF bypass capacitor between
VDD1-VSS1 and VDD2-VSS2. Furthermore, for increased precision of the D/A converter, insertion of a
bypass capacitor of about 0.01 µF is also recommended between the γ -corrected power supply
terminals (V0, V1, V2, ···, V9) and VSS2.
