MOS INTEGRATED CIRCUIT
µ PD16750
384-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 256-GRAY SCALES)
DESCRIPTION
The µ PD16750 is a source driver for TFT-LCDs capable of dealing with displays with 256-gray scales. Data input is
based on digital input configured as 8 bits by 6 dots (2 pixels), which can realize a full-color display of 16,777,216
colors by output of 256 values γ -corrected by an internal D/A converter and 8-by-2 external power modules.
Because the output dynamic range is as large as VDD2 − 0.2 V to VSS2 + 0.2 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 8-bit D/A converter
circuit whose odd output pins and even output pins respectively output gray scale voltages of differing polarity.
Assuring a maximum clock frequency of 40 MHz when driving at 3.0 V, this driver is applicable to XGA-standard TFT-
LCD panels and SXGA TFT-LCD panels. This driver is applicable to SXGA TFT-LCD panels by input display signal 2
systems (Clock divide).
FEATURES
• CMOS level input
• 384 outputs
• Input of 8 bits (gradation data) by 6 dots
• Capable of outputting 256 values by means of 8-by-2 external power modules (16 units) and a D/A converter
• Output dynamic range: VDD2 – 0.2 V to VSS2 + 0.2 V
• High-speed data transfer: fCLK = 40 MHz (internal data transfer speed when operating at 3.0 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)
• Logic power supply voltage (VDD1) : 3.3 V ± 0.3 V
• Driver power supply voltage (VDD2) : 9.0 V ± 0.5 V
• Low power control function (LPC)

Cautions 1. The power start sequence must be VDD1, logic input, and VDD2 & V0 to V15 in that order.
Reverse this sequence to shut down (Simultaneous power application to VDD2 and V0 to V15 is
possible.).
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 advised between the γ -corrected power supply
terminals (V0, V1, V2,....., V15) and VSS2.
