UPD16635 Datasheet (NEC) - 240-OUTPUT TFT-LCD SOURCE DRIVER

UPD16635, 240-OUTPUT TFT-LCD SOURCE DRIVER

The D/A converted 64-gray-scale analog voltage is output.

The display data is input with a width of 36 bits, viz., the gray scale data (6 bits) by 6 dots (2 pixels).

DATA SHEET MOS INTEGRATED CIRCUIT µPD16635 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.

UPD16635 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.
