High Definition 120 Hz Touch and Display Driver Integration Provides Narrow Border Solution for Smartphone LCD Displays

OMNIVISION Display Solutions’ TD4160 touch and display driver integration (TDDI) with interleave and sink-bump pin map reduces routing area achieving ~1.0 mm panel border. TD4160‘s advanced design supports high frame rate display and multi-finger touch applications for a-Si and LTPS panels.

The TD4160 enables 720RGB pixel high definition (HD+) resolution, up to 120 Hz display rate, and multi-finger high touch report rate for LCD smartphones. The TD4160 leverages OMNIVISION’s mature IP algorithm to provide OEM customers with reliable application support. The TD4160 is in mass production in hundreds of millions of smartphones and covers almost all tier-one OEM brands. The TD4160 provides high quality standards for customers.

Touch Features

Multi-touch coordinate sensing without ghost points
– Voltage correction circuits enhance the sensitivity (supporting automatic calibration)

RISC CPU optimized for capacitive sensing and other human interactions

Supports up to 18×32 electrodes to provide the maximum accuracy
– Analog front ends (AFEs) support up to 576 receiver pads

Supports I2C and SPI with OMNIVISION TouchComm protocol for communication with the host

Proprietary intelligent algorithms, run locally on the CPU facilitates removal of mechanical buttons and switches, which increases reliability and reduces footprint and component cost

Low power sensing modes enable wake-up gesture functionality

Face-detect proximity capability reduces cost by eliminating the need for other proximity sensing components

Display synchronization and increased voltage capability enable improved performance over discrete touch implementations

Programmable sensing speed of 50 kHz to 250 kHz to minimize noise interference

Includes support to control segmented VCOM in-cell touch scanning circuits and enable ultra-thin, low-cost integrated sensing schemes

High signal-to-noise ratio (SNR) touch AFE improves touch performance

120/60 Hz long H-blank sensing

Low power wake-up gesture (LPWG)
