Introduction
SSD2092 is a new TDDI (Touch Display Driver IC) integrating touch sensing and display driving schemes for optimal touch and display performance. It supports Thin Film Transistor (TFT) LCD panels with resolution of up to 1080RGB X 1920 (Full HD resolution). SSD2092 displays 16.7M vivid colors, and supports 1082 source outputs plus high voltage gate control signal for GIP design.
Supporting MIPI serial interface, SSD2092 enables ultra low power (<2.6mW) during sleep mode for log-on and gesture wake up. Its outstanding features also include high performance multi-touch, low latency, ultra-fast response (reporting rate 120Hz), high Signal-to-Noise Ratio (SNR) of up to 52dB, superior linearity of up to ± 0.5 mm, excellent water-proof performance and low charging noise. It supports 1mm stylus and also enables slim and compact module design.
