  • Patent number: 9523573
    Abstract: Sinusoidal signals (S1, S2) having a phase difference of 120° are output from two magnetic sensors in accordance with rotation of an input shaft. A first rotation angle computation unit computes a rotation angle ?(n) on the basis of output signals S1(n), S1(n?1), S2(n), S2(n?1) from the magnetic sensors, which are sampled at two sampling timings. At this time, the first rotation angle computation unit computes the rotation angle ?(n) on the assumption that there are no variations of amplitudes of the output signals (S1, S2) from each one of the two sensors due to temperature changes between the two sampling timings.

    Abstract: The present invention provides a method for manufacturing a highly reliable display device at a low cost with high yield. According to the present invention, a step due to an opening in a contact is covered with an insulating layer to reduce the step, and is processed into a gentle shape. A wiring or the like is formed to be in contact with the insulating layer and thus the coverage of the wiring or the like is enhanced. In addition, deterioration of a light-emitting element due to contaminants such as water can be prevented by sealing a layer including an organic material that has water permeability in a display device with a sealing material. Since the sealing material is formed in a portion of a driver circuit region in the display device, the frame margin of the display device can be narrowed.

A switching TFT 112 is provided between a connection point B between the capacitor 120 and the switching TFT 111 and the power supply wiring line Vp, a switching TFT 113 is provided between the gate and drain terminals of the driving TFT 110, and a switching TFT 114 is provided between the gate terminal of the driving TFT 110 and a reference supply wiring line Vs. A potential that brings the driving TFT 110 into a conduction state is applied to the reference supply wiring line Vs. Thus, variations in the threshold voltage of a drive element can be properly compensated for and unwanted light emission from an electro-optical element can be prevented.

  • Patent number: 8310476
    Abstract: For the purpose of providing a display apparatus capable of improving display quality by expanding the light-emission area of pixels by improving the layout of pixels and common power-feed lines formed on a substrate, pixels (7A, 7B) including a light-emission element (40), such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines (com) so that the number of common power-feed lines (com) is reduced. Further, the polarity of a driving current flowing between the pixels (7A, 7B) and the light-emission element (40) is inverted so that the amount of current flowing through the common power-supply lines “com” is reduced.

  • Patent number: 8194507
    Abstract: A hidden display may be used in an apparatus to display information to a user. The display hardware is generally hidden within the apparatus and illuminated information appears on an outside surface of the apparatus to display the information. The hidden display may couple light into a display panel from the inside of the apparatus to provide the illuminated information on the outside surface of the display panel. The display panel may provide diffuse reflection of ambient light on the outside of the display panel such that the display hardware is not visible behind the display panel but without providing a mirror-like reflection. The display may be used in a variety of different apparatuses or devices including, but not limited to, clocks and clock audio devices.

  • Patent number: 7872635
    Abstract: A system for detecting and recording eye-tracking data by presenting to an observer a display image with an area in focus surrounded by blurred areas. The observer may shift the focus area within the image by head movements which are wirelessly transmitted to a receiver and used to modify the displayed image. This system solves that part of the eye-tracking problem that is most critical for measuring cognitive processes.
