Abstract:

A method for fabricating thin DITO or SITO touch sensor panels with a thickness less than a minimum thickness tolerance of existing manufacturing equipment. In one embodiment, a sandwich of two thin glass sheets is formed such that the combined thickness of the glass sheets does not drop below the minimum thickness tolerance of existing manufacturing equipment when thin film process is performed on the surfaces of the sandwich during fabrication. The sandwich may eventually be separated to form two thin SITO/DITO panels. In another embodiment, the fabrication process involves laminating two patterned thick substrates, each having at least the minimum thickness tolerance of existing manufacturing equipment. One or both of the sides of the laminated substrates are then thinned so that when the substrates are separated, each is a thin DITO/SITO panel having a thickness less than the minimum thickness tolerance of existing manufacturing equipment.

Abstract:

A method of forming a curved touch surface is disclosed. The method can include depositing and patterning a conductive thin film on a flexible substrate to form at least one touch sensor pattern, while the flexible substrate is in a flat state. According to certain embodiments, the method can include supporting the flexible substrate in the flat state on at least one curved forming substrate having a predetermined curvature; and performing an anneal process, or an anneal-like high-heat process, on the conductive thin film, wherein the anneal process can cause the flexible substrate to conform to the predetermined curvature of the at least one curved forming substrate. According to an embodiment, the curved forming substrate can include a first forming substrate having a first predetermined curvature and a second forming substrate having a second predetermined curvature complementing the first predetermined curvature.

US Classification:

428172, 427 58, 428203

Abstract:

Substantially transparent conductor layers in touch sensing systems may be formed by forming a barrier layer between an organic layer and a substantially transparent conductive layer. For example, a barrier layer can be formed over the organic layer, and the transparent conductor layer can be formed over the barrier layer. The barrier layer can reduce or prevent outgassing of the organic layer, to help increase the quality of the transparent conductor layer. In another example, a combination layer of two different types of a transparent conductor may be formed over the organic layer by forming a barrier layer of the transparent conductor, and forming a second layer of the transparent conductor on the barrier layer. Outgassing that can occur when forming the barrier layer can cause the transparent conductor of the barrier layer to be of lower-quality, but can result in a higher-quality transparent conductor of the second layer.

Abstract:

Improved techniques are disclosed for fabrication of touch panels using thin sheet glass. Thin touch sensor panels each having a thickness of substantially less than approximately one-half millimeter can be produced. A thin mother glass sheet having a thickness of substantially less then approximately one half millimeter can be used. A thin film can be coupled to a surface of the thin mother glass sheet, and the thin film can be photolithographically patterned, while avoiding breakage of the thin mother glass sheet. The thin mother glass sheet can be singulated into the thin touch sensor panels.

International Classification:

H04B 15/00

US Classification:

375348

Abstract:

A method and system for combining a guard interval and a corresponding portion of a received symbol, whereby when receiving a signal that contains the symbol with a guard interval corresponding to the symbol, a portion of the guard interval that is free from inter-symbol interference may be extracted, and the extracted portion of the guard interval may be combined with the corresponding portion of the symbol. The extracting and combining may be done after a determining, based on a delay profile provided by the received signal, that a delay spread is smaller than a predetermined channel delay. The delay spread may be determined by filtering an instantaneous delay spread associated with the received signal. The filtering may be performed using a 1-tap infinite impulse response low-pass filter. The low-pass filter may include a time constant that is the inverse of a maximum Doppler frequency shift.

Abstract:

Methods for chemically strengthening the edges of glass sheets are provided. Voids can be formed in a mother sheet. The edges of these voids may correspond to a portion of the new edges that would normally be created during separation and free shaping of the mother sheet. The mother sheet can then be immersed in a chemical strengthener. The edges of the voids can be chemically strengthened in addition to the front and back sides of the mother sheet. After thin film processing and separation, each of the resulting individual sheets has been chemically strengthened on both sides and on a portion of its edges.
