Abstract
An image display device has touch sensing sensor components integrally distributed amongst pixel components of the device. In one embodiment, the distribution is one sensor component per one pixel component. In one embodiment, the pixel component forms a pixel portion of an image by selectively reflecting light and the sensor component is composed of a material that reflects light. More specifically, in one embodiment the light reflecting pixel component is an electrophoretic unit and the sensor component includes a layer of titanium having a color filter layer disposed below it and thus protectively covering it. Reflection of light from the light reflecting sensor layer is reduced by providing an anti-reflection layer above it. The sensor component changes resistance in response to change of local temperature or of an amount of infrared radiation impinging on it. Its resistance is measured by way of two wires connected thereto and extending through contact holes provided in the color filter layer.
