240-OUTPUT TFT-LCD SOURCE DRIVER
(COMPATIBLE WITH 64 GRAY SCALES)
The µPD16635 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 11.5 VP-P, level inversion operation of the LCD’s common electrode is rendered
unnecessary. Also, to be able to deal with full-dot 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 33 MHz when driving
at 3.0 V, this driver is applicable to SVGA-standard TFT-LCD panels.
FEATURES
• Capable of outputting 64 values by means of 5-by-2 external power modules (10 units) and a D/A converter
• Output dynamic range 11.5 VP-P min. (@ VDD2 = 13.5 V)
• CMOS level input
• Input of 6 bits (gradation data) by 6 dots
• High-speed data transfer: fmax. = 33 MHz (internal data transfer speed when operating at 3.0 V)
• 240 outputs
• Dedicaded full-dot inversion driver
• Single-sided mounting possible (loaded with slim TCP)
