Problems solved by technology

However, they still cause significant light transmission and reflection losses on the displayed image
Additionally, although more opaque resistive coatings such as conductive polymers or thin metal layers are not commercially desirable for resistive touch screens, since the conductive coating must be transparent, inexpensive, and / or perform well, and Completely opaque resistive coatings such as thicker metal layers or composites cannot be used either

Embodiment Construction

[0014] FIG. 1 illustrates a resistive touch screen 20 that generally includes a substrate 22 and a cover 26 . The touch screen 20 may be any type of resistive touch screen, including but not limited to 4-wire, 5-wire or 3-wire diodes. Substrate 22 has a top surface 25 on which conductive coating 24 is formed. Cover plate 26 has bottom surface 27 on which conductive coating 28 is formed. It should be understood that in alternative embodiments the substrate top surface 25 and / or the cover bottom surface 27 may be provided with corresponding conductive / resistive regions by means other than coatings 24 and 28, eg by particle implantation. It should also be understood that the various layers of the touch screen 20 in the figures are not drawn to scale and are for illustration purposes only.

[0015] Cover plate 26 has an outwardly facing (or top) surface 38 from which programmable display 60 is visible. As such, touch screen 20 includes internal touch sensors (conductive layers ...

Abstract

A resistive touchscreen (20) having a programmable display (60), such as an emissive display matrix of organic light-emitting diodes, or a reflective electronic paper display, built into the coversheet (26). The touchscreen may be of any resistive type, including 4-wire, 5-wire, and diode 3-wire. A touch / display system is thus provided in which there is little or no degradation of the displayed image due to image transmission through the internal touch sensor components, and in which the internal touch sensor components may be constructed of opaque materials.

Description

technical field [0001] This invention relates to touch screens; more particularly, to resistive touch screens with programmable display coversheets. Background technique [0002] A touch screen is an input device used to increase the choice of computer operating means and application categories. A conventional touch screen is a transparent input device that senses the two-dimensional location of the touch of an object such as a finger or a stylus. Touch screens are placed on display devices such as cathode ray tube monitors and liquid crystal displays to form a touch display system. For example, touch display systems are used in applications such as restaurant order entry systems, industrial process control applications, automated teller machines, personal digital assistant (PDA) devices, interactive museum exhibits, airline system check-in machines, and the like. [0003] Touch screens have been manufactured using a variety of different technologies, such as resistive (eg...
