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.

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)
