384-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64-GRAY SCALES)
DESCRIPTION
The µPD160061A 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 VSS2 + 0.2 V to VDD2 – 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 6-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
65 MHz when driving at 2.7 V, this driver is applicable to XGA-standard TFT-LCD panels and SXGA TFT-LCD panels.
FEATURES
• CMOS level input (2.3 to 3.6 V)
• 384 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): 7.5 to 9.5 V
• High-speed data transfer: fCLK = 65 MHz MAX. (internal data transfer speed when operating at VDD1 = 2.7 V)
40 MHz MAX. (internal data transfer speed when operating at VDD1 = 2.3 V)
• Output dynamic range: VSS2 + 0.2 V to VDD2 – 0.2 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)
• Apply for heavy load, light load
• Semi slim-chip shaped
