摘要： A display panel includes a liquid crystal cell, a light guide plate, and at least one light source. The light guide plate is attached to a surface of the liquid crystal cell in a thickness direction of the liquid crystal. The light guide plate includes a first surface, a second surface and side surfaces. In a thickness direction of the light guide plate, the first surface is opposite to the second surface, and the side faces are located between the first surface and the second surface. The first surface is closer to the liquid crystal cell than the second surface. A light source is disposed on at least a partial region in at least one side face. The light guide plate is configured such that light incident on the second surface in light from the light source is totally reflected, and then exits from the first surface.

摘要： An apparatus can include an electrochromic device configured to be maintained a continuously graded transmission state. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded transmission state and maintained in the continuously graded transmission state. The current during switching can be higher than current during maintaining the continuously graded transmission state. In an embodiment, the grading can be reversed to provide a mirror image of the grading. In another embodiment, at least 27% and up to 100% of the electrochromic device can be in a continuously graded transmission state. The control device can be located within an insulating glass unit, adjacent to the insulating glass unit, or remotely from the insulating glass unit. In a further embodiment, a gap between bus bars can be used to form a portion of the electrochromic device that can be continuously graded.

摘要： Methods are described for the commissioning of optically switchable window networks. During commissioning, network addresses are paired with the locations of installed devices for components on a window network. Commissioning may also involve steps of testing and validating the network devices. By correctly pairing the location of a device with its network address, a window network is configured to function such that controls sent over the network reach their targeted device(s) which in turn respond accordingly. The methods described herein may reduce frustrations that result from mispairing and installation issues that are common to conventional commissioning practices. Commissioning may involve recording a response to a manually or automatically initiated trigger. Commissioning methods described herein may rely on user input, or be automatic, not requiring user input.

摘要： A metastable light attenuator includes an electrophoretic cell having spaced-apart first and second electrodes, and electrophoretic ink therebetween including charged particles. A programmable controller applies signals to the electrodes generating an intermittent electric field across the ink to drive particles to one of a first extreme light state in which particles are maximally spread within the cell in the path of light through the cell to strongly attenuate light transmitted through the cell, or a second extreme light state in which particles are maximally concentrated within the cell and removed from the path of light through the cell and to substantially transmit light through the cell, or two or more light states intermediate the first and second light states. The controller applies intermittent signals to the electrodes to drive the particles from one intermediate state to a second intermediate state within a light transmittance range defined by the two intermediate light states to avoid flashing.

摘要： An imaging method of a head-mounted display and a head-mounted display are disclosed. The method includes, but is not limited to: detecting a wavefront of a beam emitted by the head-mounted display through its optical system; acquiring a position of a visual axis of a human eye; calculating a deviation between the visual axis of the human eye and an optical axis of the optical system; and adjusting a wavefront incident to the human eye according to the deviation, so that a correspondence between the wavefront incident to the human eye and the visual axis is consistent with a correspondence between the wavefront of the beam emitted from the optical system and the optical axis.
