UPD16772A Overview
The µ PD16772A 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 + 0.1 V to VDD2 0.1 V, level...
UPD16772A Key Features
- CMOS level input (2.3 to 3.6 V)
- 480 outputs
- Input of 6 bits (gradation 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 (RDAC)
- Output dynamic range : VSS2 + 0.1 V to VDD2
- High-speed data transfer : fCLK = 45 MHz (internal data transfer speed when operating at VDD1 = 2.3 V)
- Apply for dot-line inversion, n-line inversion and column line inversion
- Output voltage polarity inversion function (POL)
- Display data inversion function (POL21/22)
- Current consumption reduction function (LPC, Bcont)
