“…Thus, optoelectronic devices such as display screens use transparent electrodes to carry electrical signals while making the display visible [1]. In a touchscreen on the other hand, the transparent electrode not only keeps the display visible, but also translates touch into electrical signals for further processing [2]. In new generation solar cells such as organic and dye sensitized cells, the transparent electrodes while allowing light photons to fall on the active layer, extract charge carriers generated due to the photovoltaic effect [3,4].…”

“…The ITO(40)/Ag(15)/ITO(40 nm) hybrid layer shows nearly the same transmittance as the 95 nm ITO monolayer. Notably, the ITO(40)/Ag(10)/ITO(40 nm) layer shows a clearly higher transmittance (86.9%) than the ITO monolayer (81.6%), as a result of index-matching of the OMO structure [19,20]. These data confirm that the hybrid layer is a key factor determining both the electrical and optical properties.…”

Transparent film heaters (TFHs) based on Joule heating are currently an active research area. However, TFHs based on an indium tin oxide (ITO) monolayer have a number of problems. For example, heating is concentrated in only part of the device. Also, heating efficiency is low because it has high sheet resistance (Rs). To address these problems, this study introduced hybrid layers of ITO/Ag/ITO deposited by magnetron sputtering, and the electrical, optical, and thermal properties were estimated for various thicknesses of the metal interlayer. The Rs of ITO(40)/Ag/ITO(40 nm) hybrid TFHs were 5.33, 3.29 and 2.15 Ω/□ for Ag thicknesses of 10, 15, and 20 nm, respectively, while the Rs of an ITO monolayer (95 nm) was 59.58 Ω/□. The maximum temperatures of these hybrid TFHs were 92, 131, and 145°C, respectively, under a voltage of 3 V. And that of the ITO monolayer was only 32°C. For the same total thickness of 95 nm, the heat generation rate (HGR) of the hybrid produced a temperature approximately 100°C higher than the ITO monolayer. It was confirmed that the film with the lowest Rs of the samples had the highest HGR for the same applied voltage. Overall, hybrid layers of ITO/Ag/ITO showed excellent performance for HGR, uniformity of heat distribution, and thermal response time.

“…Capacitive-type touch screen panel (TSP) has grown great interest due to the intuitive user interface for portable electronic device such as mobile phones, tablet, and vehicle displays [1] [2]. In recent years, the in-cell touch is increasing used by LCD makers due to the superiorities in thickness and weight of the touch module as compared to the out-cell touch.…”
