摘要： The present invention provides co-doped zinc oxide to flat panel, light emissive display devices and vacuum microelectronic devices to improve their efficiency and lifetime. This material has a low growth temperature and is compatible with metal oxide semiconductor (MOS) processing technology. It is tranparent, chemically stable and has a low work function, which result in many advantages when being used as the cathode for the aforementioned devices. In one embodiment of the emissive display device, an organic light diode (OLED) display has a high work function metal anode, such as platinum (Pt), gold (Au) or nickel (Ni) and a low work function co-doped zinc oxide cathode. Because of the energy level alignment provided by these two materials, the potential energy barriers to injection of electrons from the cathode and holes from the anode into the organic emissive medium are minimized so the display device operates more efficiently.

摘要： The present invention relates to thin film retardation plates, such as cholesteric and A-plate compensators, for improving the viewing angle and contrast of liquid crystal displays. The A-plate is fabricated using a single substrate onto which a layer of polymerizable reactive mesogens (RMs) is solvent cast. Included in the RMs solution is an additive that migrates to the RM/air interface to lower the surface energy and generate an additive-rich surface layer, which in turn lowers the intrinsic tilt angle of the RMs at the air interface to between 25 degrees (25.degree.) and about zero degrees (0.degree.). The solvent is evaporated and the resulting film is polymerized in the liquid crystal phase to permanently orient the liquid crystal. The resulting film may be readily separated from the substrate and shaped into any desired pattern and combined to form novel compensators. In an alternative embodiment, a tilt may be provided by treating the substrate with an oblique alignment layer to form a compensator having a defined splay through the bulk of the thin film.

摘要： An electronic device is operable to determine a touch input applied to a capacitive touch panel system thereof so as to account for time-varying noise affecting the touch panel system. The electronic device includes the touch panel system, an analog-to-digital conversion (ADC) unit, and a processing unit. The processing unit is operable to: receive digital signal values from the ADC unit representing capacitances detected by sensing points of the touch panel system; adjust at least one of the digital signal values based at least on a time-varying noise to produce at least one noise-adjusted value; and determine the touch input based on the at least one noise-adjusted value. In one embodiment, the electronic device determines the time-varying noise prior to adjusting the digital signal values. In another embodiment, the time-varying noise is produced by a display panel of a touchscreen display that also includes the touch panel system.

摘要： A mobile electronic device and corresponding method have a user interface for receiving a touch input. The mobile electronic device includes a capacitive sensor having an electrode layer with non-etched away portions and etched away portions, and having isolation areas formed in the etched away portions, and a segmented optical shutter disposed on a side of the capacitive sensor, the optical shutter including a liquid crystal layer sandwiched between a top absorbing polarizer and a bottom absorbing polarizer, and including a reflectance increasing element disposed between the liquid crystal layer and the bottom absorbing polarizer. A reflectance of the reflectance increasing element is selected to reduce a ratio of a reflectance through the non-etched away portions to a reflectance through the etched away portions to make an appearance of the user interface substantially uniform in an off state.

摘要： A dual-sided electrophoretic display (700) having a first region (701) and a second region (702) is provided. Each of the first region (701) and the second region (702) includes selectively operable members (703,704) that function as pixels for presenting images on the electrophoretic display (700). Each of the selectively operable members (703,704) is driven by a driver circuit (710) by way of corresponding thin film transistors and capacitors (742,742), which are opaque. As the selectively operable members (704) of the second region (702) are bigger than are the selectively operable members (703) of the first region (701), the aperture ratio of the selectively operable members (704) of the second region (702) is greater than in the first region (701) when viewed from the rear side (730). Thus, a contrast ratio of the second region (602), when viewed from the rear side (730) is sufficiently high that text, icons, and characters presented in the second region (602) are legibly visible on the rear side (730).

摘要： A two-way trans-reflective display pixel (100) having two viewable sides (102, 104) is disclosed. The two-way trans-reflective display pixel has a first transparent layer (106), a second transparent layer (108), and light modulating medium (110) sandwiched between them. Both the first and second transparent layers (106, 108) have light reflectors (132, 136) and light absorbers (130, 134), which allow light entering from either viewable sides (102, 104) to partially reflected, partially absorbed, and partially transmitted, allowing an image to be viewable from both viewable sides (102, 104). A two-way trans-reflective display (402) comprising a plurality of two-way trans-reflective display pixels (100) and a transparent light source (412) is also disclosed. The transparent light source (412) provides color light, and enables an image from the two-way trans-reflective display (402) to be viewable in color from both first and second viewable sizes (418, 602).

摘要： Disclosed are methods of user interfaces of electronic devices having a displays configured to annunciate wallpaper images wherein a wallpaper image includes image data. Image data can be characterized, for example, by the luminance levels of pixels of the image and/or the power needed to display the image. An image characteristic threshold is related to current drain impact, for example, in terms of luminance and/or power needed to display an image. A disclosed method can include receiving the image data of the wallpaper image and determining whether the image characteristic of the image data (such as luminance level at a given percentile) exceeds the image characteristic threshold. A disclosed method can further provide generating a user interface notification relating to the image characteristic exceeding the image characteristic threshold and relating to the current drain impact of displaying the image as wallpaper.
