摘要： A pixel electrode or a common electrode is a light-transmissive conductive film; therefore, it is formed of ITO conventionally. Accordingly, the number of manufacturing steps and masks, and manufacturing cost have been increased. An object of the present invention is to provide a semiconductor device, a liquid crystal display device, and an electronic appliance each having a wide viewing angle, less numbers of manufacturing steps and masks, and low manufacturing cost compared with a conventional device. A semiconductor layer of a transistor, a pixel electrode, and a common electrode of a liquid crystal element are formed in the same step.

摘要： An electrical characteristic of a privacy glazing structure and indicative of a health of the privacy glazing structure can be measured at a first time and at a second time later than the first time. In response to detecting a change in the electrical characteristic indicating a change in the health of the privacy glazing structure, one or more parameters of an electrical drive signal can be adjusted to compensate for the change in the health of the privacy glazing structure. The electrical characteristic can be measured at a plurality of times after the second time and compared to the electrical characteristic measured at the first time. If, at any of the plurality of times, the measured electrical characteristic differs from the electrical characteristic measured at the first time by more than a threshold amount, one or more parameters of the electrical drive signal can be adjusted.

摘要： A display device includes a first substrate, a second substrate, a display functional layer, first electrodes, pixel electrodes, second electrodes, a drive circuit, and a conductive body. The second substrate faces the first substrate. The display functional layer is provided between the first substrate and the second substrate. The first electrodes are provided between the first substrate and the second substrate. The pixel electrodes face the first electrodes between the first substrate and the second substrate. The second electrodes overlap the first electrodes through the display functional layer. The drive circuit supplies drive signals to a pair of the first electrode, wherein the drive circuit supplies a first electric potential to one of the pair of first electrodes and supplies a drive signal having a second electric potential different from the first electric potential to the other of the pair of first electrodes simultaneously.

摘要： A system for and method of projecting augmentation imagery in a head-mounted display is disclosed. A system for projecting light onto an eye includes a display to project light, a beam combiner, first and second optical systems between the display and the beam combiner along respective first and second optical paths. The first and second optical paths differ. The system also includes a switchable reflector that, in a reflective state, reflects light incident upon the reflector, and, in a non-reflective state, transmits light incident upon the reflector. The reflector is between the display and the first and second optical systems along the first and second optical paths and directs light along the first path, in the reflective state, or along the second path, in the non-reflective state, to reflect light from the beam combiner to the eye from different directions when in the different states.
