An optical see-through head-mounted display device includes a see-through lens which combines an augmented reality image with light from a real-world scene, while an opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of the LCD panel can be selectively controlled to be transmissive or opaque, based on a size, shape and position of the augmented reality image. Eye tracking can be used to adjust the position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or a representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.

The present disclosure provides a handwritten screen and a control display device. The handwritten screen includes a plurality of pixels arranged in an array, and a first substrate and a second substrate both being electrically insulating and thermally conductive. Each of the plurality of pixels includes a thermoelectric generator and a display unit connected with each other, the thermoelectric generator and the display unit are between the first substrate and the second substrate, and the thermoelectric generator generates an electric field once there is a difference between a temperature of the first substrate and a temperature of the second substrate, so as to supply power to the display unit. The present disclosure effectively utilizes a difference in temperature between a finger (i.e., the first substrate) and an external environment (i.e., the second substrate) during touch, and converts thermal energy into electrical energy to perform thermoelectric power generation.

The present disclosure discloses a mirror display apparatus and a corresponding method, the apparatus including a mirror display unit configured both to display an information image and as a mirror, a detection unit configured to detect a first area in the mirror display unit corresponding to a human body in front of the mirror display unit and a processing unit configured to adjust a position of a second area for displaying an information image in the mirror display unit in response to the detection of the first area by the detection unit, such that the second area is outside the first area.

Methods and controllers for driving a light-collimating film including elongated chambers of bistable electrophoretic fluids. The light-collimating films are suitable to control the amount and/or direction of light incident to a transmissive substrate. Such films may be integrated into devices, such as LCD displays, to provide a zone of privacy for a user viewing the LCD display. Because the light-collimating film is switchable, it allows a user to alter the collimation of the emitted light on demand. Because the films are bistable, they do not require additional power after they have been switched to a display state.

To provide a display device that makes speckles on a screen difficult to be visually recognized and allows an observer to easily observe an image projected on the screen easily. A display device includes a projector that emits coherent light, a screen that projects the coherent light emitted from the projector, and a first optical system that guides transmitted light or diffused light of the screen to an observing direction of an observer, and allows an observer to observe a real image or a virtual image of an image projected on the screen. The screen includes a plurality of particles including a first portion and a second portion, a particle layer having a plurality of particles, electrodes for applying a voltage to the particle layer to generate an electric field for driving the particles of the particle layer.

Gravitational Janus microparticle having, a center-of-mass, a center-of-volume, and a nonuniform density, wherein: the center-of-mass and the center-of-volume are distinct. When suspended in a fluid, the microparticle substantially aligns with either: i) the gravitational field; or ii) the direction of an acceleration, such that the Janus microparticle is in substantial rotation equilibrium. After perturbation from substantial rotational equilibrium, the Janus microparticle reversibly rotates to return to substantial rotational equilibrium. The gravitational Janus microparticle may comprise at least two portions, each having distinct physical and/or chemical characteristics, wherein at least one portion provides a detectable effect following rotation and alignment of the microparticle.

To provide a display device including a flexible panel that can be handled without seriously damaging a driver circuit or a connecting portion between circuits. The display device includes a bent portion obtained by bending an element substrate. A circuit for driving the display device is provided in the bent portion and a wiring extends from the circuit, whereby the strength of a portion including the circuit for driving the display device is increased and failure of the circuit is reduced. Furthermore, the element substrate is bent in a connecting portion between an external terminal electrode and an external connecting wiring (FPC) so that the element substrate provided with the external terminal electrode fits the external connecting wiring, whereby the strength of the connecting portion is increased.
