Abstract: An electronic device includes a display for rendering content. The display may include a protective sheet that is located between an image-displaying component and a liquid optically clear adhesive (LOCA) that adheres another component layered atop the display, such as a front light, a touch sensor or a cover layer. In some cases, the protective sheet may be a polymer sheet coated with a layer of ceramic material that prevents migration of a reactive species, such as a photoinitiator, between the protective sheet and the LOCA. Alternatively, a plasma treatment, a UV-light-ozone treatment, or a thermal treatment may be applied to the protective sheet to remove material including the reactive species and/or form a barrier layer to prevent migration of the reactive species. Still alternatively, the protective sheet may be a thin flexible glass sheet that does not include constituents that interact with the LOCA.

Abstract: Techniques for utilizing different versions of a same font when rendering subsequent portions of a content item. For instance, envision that a user requests to open an electronic book. In response to this request, a display controller may display the first page of the electronic book using a flashing update and, therefore, may display the text using a regular weight of a particular font. However, when the user subsequently requests to turn to the second page of the electronic book, the display controller (utilizing a non-flashing update) may update the display using a version of the same font having a lesser weight. Given that some level of bleeding with likely occur when using the non-flashing update, the lesser weight coupled with the bleeding may result in text that approximates the weight of the text of the first page of the electronic book.

Abstract: The ability to effect a change in capacitance is not limited to one side of a capacitive touch element. Objects on an opposite side, or approaching from the opposite side, of a touch element can distort the electrostatic field. In some instances, overall device thickness can be such that the presence of a user's fingers on the back of a portable computing device (e.g., when holding the device) can be sensed by the capacitive touch screen on the front of the device. In various embodiments, a metallic plain, shield, or other conductive layer is provided for devices such as, smartphones, tablet computers, and other computing devices to eliminate, or at least reduce, any potential measurable change in capacitance caused by objects behind the touch panel.

Abstract: Electrophoretic display units (1) comprising pixels (11) situated between common electrodes (6) and pixel electrodes (5) need, for shortening the total image update times, increased driving voltages across the pixels (11) which endanger transistors (12) coupled to the pixel electrodes (5). These increased driving voltage (V6) to the common electrode (6). To protect the transistors (12) against these increased driving voltages, a setting signal (S1, S2) is supplied to the pixel electrode (5) via the transistor (12) for reducing a voltage across the pixel (11) resulting from a transition in the alternating voltage signal (V6). During driving frame periods (Fd) data pulses (D1, D2, D3, D4, D5, D6) are supplied, and during setting frame periods (Fs), the setting signals (S1, S2) are supplied.

Abstract: An optical device provides optical routing functions, such as switching or redirecting of optical signals. The device utilizes one or more control light beams, which couple through a top surface of a planar substrate (via relatively small control windows) into one or more preselected regions of optical channels formed in the substrate. The presence of a control light beam at a control window increases the refractive index of the nonlinear optical medium of a portion of a channel. The portion of the channel includes a structure that functions as an on/off filter to reflect or transmit an optical signal propagating in the channel in a manner that is responsive to the intensity of the control light beam applied to the portion of the channel. In some embodiments, the optical channels interrupt a 2D PBG structure, which functions as a boundary for the optical channels.
