International Classification:

G01R 27/28
G01R 31/28

US Classification:

324627, 29593

Abstract:

Methods and devices for testing flex cable shielding of a consumer electronic device are provided. In one example, a method may include applying a signal across a first portion of the flex cable shielding and a second portion of the flex cable shielding. The method may also include detecting a parameter associated with the signal. The method may include determining a health of the flex cable shielding based at least partially on the detected parameter.

International Classification:

G06F 3/044

Abstract:

A compliant material, such as a conductive foam, is positioned in the dielectric or capacitive gap between drive and sense electrodes and/or other conductive elements of a capacitive and/or other force sensor, such as a TFT or other display element and a sensor assembly. The compliant material prevents damage by preventing and/or cushioning contact. The compliant material may be conductive. By being conductive and being positioned between the electrodes while still being separated from one or more of the electrodes, the compliant material also shortens the effective electrical distance between the electrodes. As a result, the force sensor may be more sensitive than would otherwise be possible while being less vulnerable to damage.

G06F 3/0354
G09G 3/36
G06F 3/044

Abstract:

Touch sensor panel configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of the touch sensor panel are disclosed. In some examples, electrodes with more linear signal profiles are correlated with lower wobble error. In some examples, diffusing elements formed of floating segments of conductive materials can diffuse signal from a stylus to a plurality of electrodes, thus, making the signal profiles associated with the electrodes more linear. In addition, diffusing elements can be configured to improve the optical uniformity of the touch sensor panel. In some examples, the diffusing elements can be formed on the same layer as floating dummy pixels and resemble a plurality of merged floating dummy pixels.

Abstract:

A polarizer includes a polarizer component having a top surface and an opposite bottom surface. The bottom surface is configured to couple to a color filter layer for a liquid crystal display. The polarizer also includes a transparent conducting layer disposed over the top surface. The transparent conducting layer being configured to electrically shield the LCD from a touch panel. The polarizer further includes a coating layer disposed over the transparent conducting layer.
