The fabrication of a touch sensor panel having co-planar single-layer touch sensors fabricated on the back side of a cover glass is disclosed. It can be desirable from a manufacturing perspective to perform all thin-film processing steps on a motherglass before separating it into separate parts. To perform thin-film processing on a motherglass before separation, a removable sacrificial layer such as a photoresist can be applied over the thin-film layers. Next, the motherglass can be scribed and separated, and grinding and polishing steps can be performed prior to removing the sacrificial layer. In alternative embodiments, after the protective sacrificial layer is applied, the bulk of the coverglass can be dry-etched using a very aggressive anisotropic etching that etches primarily in the z-direction. In this embodiment, the etching can be patterned using photolithography to create rounded corners or any other shape. The photoresist can then be removed.

The applied force location [X, Y] can be determined from measures of cover glass tilt, force at particular points, and capacitive sensing of touch location.

Methods and apparatus for preventing fluctuations in ambient light from affecting the optical input mechanism of a liquid crystal display device. In one embodiment, an independent light source is adapted to generate electromagnetic signals through the cover glass of the display device.

One or more photosensors monitoring the presence of these reflected signals service the various regions on the touch panel where input may be detected. Thus, when the reflected signals are detected at a certain region, the user's finger may be assumed to be present.

Detecting force and touch using FTIR and capacitive location. FTIR determines applied force by the user's finger within infrared transmit lines on a touch device. A pattern of such lines determine optical coupling with the touch device. Capacitive sensing can determine (A) where the finger actually touches, so the touch device more accurately infers applied force; (B) whether finger touches shadow each other; (C) as a baseline for applied force; or (D) whether attenuated reflection is due to a current optical coupling, or is due to an earlier optical coupling, such as a smudge on the cover glass. If there is attenuated reflection without actual touching, the touch device can reset a baseline for applied force for the area in which that smudge remains. Infrared transmitters and receivers are positioned where they are not visible to a user, such as below a frame or mask for the cover glass.

Apparatus, systems and methods for increasing the strength of glass are disclosed. The strengthening of one portion of the glass article can be performed to a greater degree than another portion. Additionally, to mitigate against any distortion, such as warpage, physical manipulation of the glass article can be performed prior to or during strengthening, namely chemical strengthening. For example, in accordance with one embodiment, an outer surface of a glass article (e.g., cover glass) can be chemically strengthened to a greater degree than an inner surface of the glass article, yet the asymmetric strengthening does not induce distortion of the glass article because the glass article was physically manipulated, such as being bent, to counter any such distortion. Accordingly, glass articles that have undergone chemical strengthening processing are able to be not only thin and undistorted but also sufficiently strong and resistant to damage. The strengthened glass articles are well suited for use in consumer products, such as consumer electronic devices (e.g., portable electronic devices).
