In-cell adaptive touch technology for a flexible e-paper display

Solid-State Electronics, 2011
Abstract In-cell adaptive touch technology for use in an electrophoretic display (EPD) has been developed and implemented in 11.5 in. UXGA flexible electronic paper display. Here, two types of a-Si:H photo-sensor arrays fabricated on a stainless steel substrate at the process temperature of 250 °C have been used along with an overall capacitive ...

35‐2: Development of IGZO UHD In‐Cell Touch Panel LCD for Notebook PC

SID Symposium Digest of Technical Papers, 2021
We have developed the world's first IGZO UHD in‐cell touch panel LCD for Notebook PC (as of December 2020, according to our research). In addition, its four‐sided narrow border feature was achieved by COF mounting and source DeMUX. The touch panel performance has been qualified for mass‐production by internal validation.

P‐16.12: Development of High Performance In‐cell Touch Panel based on Oxide TFT

SID Symposium Digest of Technical Papers, 2021
In‐cell touch panel based on oxide TFT possesses excellent display performance, high SNR and supports LPWG function with lowest power consumption. However, due to the discrete electrode VCOM and low leakage current characteristics of oxide TFT, it is easy to cause static electricity and charge residual.

The technologies of in‐cell optical touch panel with novel input functions

Journal of the Society for Information Display, 2011
Abstract— The technologies behind an in‐cell optical touch‐panel LCD with novel input functions will be described. By improving both the optical and electrical signal‐to‐noise ratio (SNR), a touch‐panel operation robust to ambient conditions can be achieved with a low‐power consumption suitable for integration into mobile products.

P‐11.5: Investigation on the Brightening of In‐cell Touch Notch Display

SID Symposium Digest of Technical Papers, 2019
In this article, we have employed this analysis on 5.69 inch panel. There are two white blocks on the left and right sides of the notch area. Those blocks look brighter than the other area. By means of modulating the timing of gate, we have succeeded to cover the luminance difference between two areas.

Automotive Electromagnetic Compatibility Standard Specific Pulse Driving Method for Advanced In-Cell Touch Sensor

IEEE Sensors Journal, 2021
In this work, a novel pulse driving method for advanced in-cell touch (AIT) panels is proposed to meet the automotive electromagnetic interference (EMI) requirements. AIT panels are usually driven by load-free driving (LFD) to overcome the large parasitic capacitances of the in-cell touch sensors.

A Noise-Immune High-Speed Readout Circuit for In-Cell Touch Screen Panels

IEEE Transactions on Circuits and Systems I: Regular Papers, 2013
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 method, a differential sensing scheme effectively cancels common noise components and locally occurring noise is spatially low-pass filtered.

Capability Assessment for Weibull In-Cell Touch Panel Manufacturing Processes With Variance Change

IEEE Transactions on Semiconductor Manufacturing, 2014
Since touch panels can provide natural user-interface, including fluent multipoint touch or advance gesture recognition, recently they have been extensively applied in various portable devices, such as smart phones and tablet PCs. In-cell touch panel is the highest integration touch technology as compared to the on-cell and typical touch panel ...
