This paper presents the latest progress in development and applications of the capacitive
touch systems (CTSs) with styli. The CTSs, which include the touch sensor, analog front-end …

In this paper, we propose a classification approach for ambiguously shaped defects found
on the surface of a type of display panel module that is widely used in the field of mobile …

This paper presents a novel 7-in capacitive touch panel (CTP) system with a smooth tracking
algorithm that accurately estimates the position where the panel is touched and tracks the …

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 …

This paper describes a capacitive touch-screen panel (TSP) readout IC that provides a
reconfigurable SNR and frame rate with high noise immunity and touch sensitivity. The …

Capacitive touch-screen panels (TSPs) are widely used in recent high-end mobile products
on the basis of their high quality of touch features, as well as superior visibility and durability …

This article presents a continuous-time (CT) delta–sigma () capacitance-to-digital converter
(CDC) intended for use in applications with high capacitance resolution (tens of aF), and a …

The present invention is a graphical user interface in a computing device having a processor
running an operating system and a display. The graphical user interface comprises a touch …

This paper presents a readout method and circuit for large, capacitive-type touch-screen
panels (TSPs). Despite the considerable amount of RC time delay of large-area TSPs, the …

Delta-Integration, a novel readout method, is introduced in an effort to solve the noise and
speed issues impeding the performance of in-cell touch screen panels. In the proposed …
