Touchscreens have been studied and developed for a long time to provide user-friendly and
intuitive interfaces on displays. This paper describes the touchscreen technologies in four …

A touch controller is proposed for on-cell capacitive touch screen panel systems. The
proposed IC adopts the differential sensing method to enhance the dynamic range of …

In this paper, a highly area-efficient controller for capacitive touch screen panels (TSPs) is
proposed. The proposed controller uses a 10-bit successive approximation register analog …

A resistive touchpad was developed employing paper, pencil graphite, and
polydimethylsiloxane (PDMS). A pair of flexible substrates with one side coated with …

Sunlight readable transflective liquid crystal displays, used on devices from cell phones and
portable media players, to GPS and even some desktop monitors, have become …

An active matrix touch sensor is integrated into a liquid crystal display (LCD) panel. The
sensor is composed of a liquid crystal capacitor and a sensing circuit with amorphous silicon …

Photo-generation properties in an amorphous SiGe: H thin film transistor (TFT) were
characterized by analyzing the electrical performances under illumination. The a-SiGe: H …

Abstract The a‐SiGe: H TFT photosensor for embedded touch screen panel (TSP) was
characterized compared with a‐Si: H TFT. The photo sensitivity of a‐SiGe: H sensor at 850 …

Abstract Design guidelines for large size liquid crystal capacitive sensor panels have been
studied. Based on a model taking both column spacer and glass deformation into account …

We present two types of touch in-cell technology for active-matrix liquid crystal displays
(AMLCDs) with liquid-crystal capacitance detector arrays embedded in a hydrogenated …
