312 OUTPUT TFT-LCD SORCE DRIVER
(COMPATIBLE WITH 64 GRAY SCALES)
The µPD16633B 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 9.8 VP-P, level inversion operation of the LCD’s common electrode is
rendered unnecessary. Also, to be able to deal with dot-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 45 MHz when driving at 3.0
V, this driver is applicable to XGA-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 9.8 VP-P min. (@VDD2 = 10.0 V)
• CMOS level input
• Input of 6 bits (gradation data) by 6 dots
• High-speed data transfer: fmax. = 45 MHz (internal data transfer speed when operating at 3.0 V)
• 312 outputs
• Apply for only dot inversion
• Display data inversion function (POL2 terminal.)
• Single bank arrangement is possible (loaded with slim TCP)
