  • Patent number: 9892874
    Abstract: A luminous keyboard includes a keypad module, plural light-emitting elements, a light guide plate and a reflecting plate. The reflecting plate has plural light amount control structures. The light amount control structures are disposed on the reflecting plate, and located near the corresponding light-emitting elements. When the plural light-emitting elements emit light beams, the portions of the light beams that are not subjected to total internal reflection within the light guide plate are reflected by the reflecting plate. When the light beams are transferred through the light amount control structure, the reflected fraction of the light beams is reduced. Since the light beams are not very centralized, the problem of generating bright spots will be diminished.

  • Patent number: 9347649
    Abstract: This disclosure provides systems, methods and apparatus for reducing ambient light reflections from a surface of a display device in a power efficient manner. The display device includes a reflecting circular polarizer (RCP) and an absorbing circular polarizer (ACP) having the same polarity. The RCP provides light recycling functionality, while the ACP provides ambient light reflection suppression. In some implementations, the light generated by the display device is polarized by the RCP before it is incident on the ACP, which is located at the front of the display device. Because the polarities of the RCP and the ACP are the same, the ACP substantially passes all of the incident polarized light towards the front of the display device.

  • Patent number: 8405690
    Abstract: A technique for modulating light by an optically addressed, electric charge accumulating spatial light modulator achieves substantially monotonic gray scale response. Embodiments digitally modulate the voltage across a photoreceptive material included in the spatial light modulator. The digital modulation scheme entails illuminating the photoreceptor with a series of light pulses propagating from an LCoS, in which the durations of the light pulses and their positions in time combine to produce binary-weighted equivalent rms voltages on the photoreceptor. The light pulses originate from a light-emitting diode or other switchable light source, and the timing of the light pulses is controlled such that they are emitted only when the associated LCoS is in a stable state. Emitting light pulses while the LCoS is in a stable state avoids non-monotonic behavior.

  • Patent number: 8164818
    Abstract: Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.

  • Patent number: 8154781
    Abstract: A holographic display device comprises a first OLED array writing onto a first OASLM, the first OLED array and the first OASLM forming adjacent layers, and a second OLED array writing onto a second OASLM, the second OLED array and the second OASLM forming adjacent layers. The first and the second OASLMs encode a hologram and a holographic reconstruction is generated by the device when an array of read beams illuminates the first and second OASLMs and the first and second OASLMs are suitably controlled by the first and second OLED arrays. Advantages include that this device permits independent control of phase and amplitude, and the device lends itself to compactness.
