New LCD Drivers for Highest Optical Performance

NXP’s latest Generation of LCD Drivers is specifically designed for – but not limited to – driving very high-contrast, true black background Vertical Alignment Displays featuring an extremely wide viewing angle.

Overview

NXP’s latest Generation of LCD Drivers are specifically designed for – but not limited to – driving vertical alignment (VA) displays that feature higher contrast, wider viewing angle, real black background and superior image quality. They are available as either cased products for surface mount application, or as uncased products for direct chip-on-glass (COG) application. Highly integrated, the ICs offer very reliable and cost-effective solutions that ease design and - when mounted on glass - save additional board space.

They are ideal for a host of automotive, industrial, white goods, and medical displays and are widely used in banking, retail and signage applications. Their optimized drive schemes offer higher VLCD voltage, and programmable and calibrated frame frequencies, making them ideal for interfacing to VA displays.

They are available as Segment Drivers, Dot-Matrix Drivers or Character Drivers.
