Abstract
Transparent Conducting Oxide (TCO) materials such as Fluorine Tin Oxide (FTO) and Indium Tin Oxide (ITO) due to their optical and electrical properties are used in touch screens as electrodes and wires. This paper proposes a novel technique of using Electrical Resistivity Tomography (ERT) method in order to produce touch screens without pattering. Unlike existing techniques, the proposed methodology employs a uniform TCO coated screen with a maximum optical transmittance to convert the touch point coordinates into side electrodes voltages. The performance of the proposed method is tested experimentally on a FTO coated glass with a sheet resistance of 20 ohms/sq. The proposed methodology is found to be less complicated and low cost, since no pattern or electrodes are implemented in the display area. |
