P‐100: Driving Technology of Super Large Full In Cell Touch LCD

SID Symposium Digest of Technical Papers, 2022
This paper introduces a self‐contained ultra‐large In Cell Touch driving scheme, which can be applied in 43 inch, 86 inch and larger In Cell Touch products. This driving scheme divides the VCOM electrodes in the liquid crystal cell for traditional LCD into several Sensor blocks, uses display and touch time‐sharing to drive the signal, modulates the ...

LCD In‐Cell Touch

Information Display, 2010
Imagine being able to touch the surface of any display with your finger or a stylus and have the location of your touch instantly identified down to the exact pixels. Imagine this happening with no cover glass or special coatings or any other obstruction in front of the display, and with minimal change inside the display.

A compact gate driver with bifunctional capacitor for in‐cell touch mobile display

Journal of the Society for Information Display, 2021
AbstractA thin‐film transistors (TFTs) integrated gate driver circuit with bifunctional capacitors for in‐cell touch with horizontal blanking display mode is proposed in this paper. The coupling capacitor, which conventionally enables low‐level‐maintaining parts in display periods, is reused to store transfer charges during touch detection periods ...

3.5: Novel Touch Sensitive In‐Cell AMLCD

SID Symposium Digest of Technical Papers, 2004
Abstract A touch sensitive Active Matrix Liquid Crystal Display (AMLCD) that obviates the need to have a transparent touch panel mounted on top of the LCD, in the viewer side, is realized. This is achieved through the introduction of a resistive touch‐sensitive mechanical switch into the pixel.

39‐1: Mutual‐Capacitance in‐Cell Touch Panel

SID Symposium Digest of Technical Papers, 2016
The mutual‐capacitance fully in‐cell touch panel (iTP) has developed by AUO. Touch sensors are integrated on TFT substrate and the design is different with traditional mutualcapacitance iTP. We've verified the design and structure on 5″ HD AHVA panel and driven the panel successfully. It supports multi touch and without any optical characteristic decay.

An IGZO TFT based in-cell capacitance touch sensor

2012 IEEE 11th International Conference on Solid-State and Integrated Circuit Technology, 2012
An in-cell active matrix capacitive touch sensor using IGZO TFT is proposed in this paper. The sensor does not need touch deformation, complicated detection mechanisms or extra components. In the sensor, touching events are identified as capacitive coupling between internal detection electrodes and touch objects.

58.2: In‐Cell Type Adaptive Touch for Electrophoretic Display

SID Symposium Digest of Technical Papers, 2009
Abstract In‐cell type adaptive touch technology for Electro‐Phoretic Display has been developed and implemented in 2.1 inch QVGA electronic paper. Here, we have used two types of a‐Si photosensor arrays along with overall capacitor and applied touch algorithm adapted depending upon the amount of light intensity, resulting in enhancing

32‐1: Transparent Conductive Film at In‐Cell Touch Structure

SID Symposium Digest of Technical Papers, 2016
Generally, ITO (Indium Tin Oxide) is almost universally used to remove ESD(Electro Static Discharge), external electric shock at the IPS Mode in LCD. However, ITO cannot be used at In‐cell touch because it has got a high conductivity. So we have developed a new material that can replace ITO and would like to introduce the research result.

High-definition in-cell touch panel with parallel scanning method

2016 23rd International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD), 2016
We have developed a high-definition in-cell (HDI) touch panel technology that uses a parallel scanning method. This technology can be incorporated into various TFT backplanes including LTPS TFT and IGZO TFT. We have developed 5.7” WQHD LTPS LCD and 4.95” FHD IGZO LCD, both of which are integrated in-cell touch panels.

In-cell capacitive touch panel structures and their readout circuits

2016 23rd International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD), 2016
This paper proposes an in-cell capacitive touch panel structure and a readout circuit (ROIC) to sense the variation in self-capacitance using a small number of sensing lines. The proposed touch panel structure sequentially senses the variation in self-capacitance by adding a thin-film transistor and a scan signal line into each touch sensor so that the
