10-Channel Scan Driver for TFT LCD with GPM Function

Active: In Production.

The MAX17119 includes a 10-channel high-voltage level-shifting scan driver with a gate pulse modulation (GPM) feature to shape the corner of the scan driver output in order to reduce flicker. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications.

The high-voltage level-shifting scan driver is designed to drive the TFT panel gate logic. Its 10 outputs swing from +38V (maximum) to -12V (minimum) and can swiftly drive capacitive loads. There are two positive supply inputs that provide flexibility for system design.

The GPM feature is employed to shape the corner of the falling edge of the clock channels. This reduces flicker, and therefore improves the display quality.

The MAX17119 also features a dedicated discharge channel and an integrated voltage detector. When the system shuts down, the voltage detector commands the discharge channel to swing its output to positive supply voltage so as to remove any residual image on the display quickly.

The MAX17119 is available in a 28-pin, 5mm x 5mm thin QFN package with a maximum thickness of 0.8mm for thin LCD panels.
