A storage container includes: a sidewall portion, a seal portion and a movable member. The sidewall portion, the seal portion and the movable member define an accommodation space. The seal portion is adapted to seal a top of the sidewall portion, and the seal portion is provided with a hole communicated with the accommodation space. The movable member is adapted to seal a bottom of the sidewall portion, and further adapted to move up and down in parallel to a direction of the bottom of the sidewall portion pointing to the top. The movable member is configured to connect a control device. The control device controls the movable member to move up and down in a direction of the bottom of the sidewall portion pointing to the top.

A display device is provided. The display device includes a display panel and a visible angle adjustment panel. The visible angle adjustment panel has a liquid-crystal layer. The liquid-crystal layer has a plurality of cell gaps, wherein the thicknesses of the cell gaps are different from each other, and the thicknesses of the cell gaps gradually increase along a direction.

A display device includes a directional illuminator providing a light beam, a display panel downstream of a directional illuminator, for receiving and spatially modulating the light beam, and a beam redirecting module downstream of the display panel, for variably redirecting the spatially modulated light beam. Steering the illuminating light by the beam redirecting module enables one to steer the exit pupil of the display device to match the user's eye location(s).

A display device includes a liquid crystal display including a first liquid crystal display panel that displays a character or an image; a decorative member; and a controller that controls the display of the liquid crystal display. The decorative member is disposed on a display surface side of the liquid crystal display, and includes a display region in which the display of the liquid crystal display is transparently displayed, and a non-display region adjacent to the display region. The controller controls a luminance through the decorative member of a black display of the liquid crystal display to a luminance invisible to a user, and controls the luminance through the decorative member of a low-gradation region, except for the black display, of the liquid crystal display to a luminance visible to the user.

A display device includes a display panel including a first area, a second area, and a bending area disposed between the first area and the second area, the bending area having a curvature radius, a data driver disposed on the display panel and overlapping the second area in a plan view, and a bending protection layer disposed on the display panel and the data driver and overlapping the first area in a plan view, the bending area, and the second area. The bending protection layer includes a thermochromic pigment having a light transmittance that varies according to a temperature.

A privacy function structure, a display panel, and a display device are provided in the present disclosure. The privacy function structure includes a privacy state and a non-privacy state. The privacy function structure includes a first conductive layer, a privacy liquid crystal layer, a light-transmitting cover plate, and a second conductive layer. The privacy liquid crystal layer is disposed on a side of the first conductive layer, the light-transmitting cover plate is disposed on a side of the privacy liquid crystal layer away from the first conductive layer, and the second conductive layer is disposed on a side of the light-transmitting cover plate facing the first conductive layer. The second conductive layer includes multiple conductive strips mutually parallel. By controlling on and off of the multiple conductive strips, the privacy function structure is switched between the privacy state and the non-privacy state.

An optical apparatus includes an image source, a relay optical system, and an optical processing system. The image source is configured to display an image. The relay optical system is configured to project the image displayed by the image source to the optical processing system, and to image at infinity. The optical processing system is configured to project incident light from the relay optical system in a same direction to at least two preset directions sequentially.

A light modulating device including: a light transmissive plate having a curved surface; a light modulating cell; and an optically transparent adhesive film which is disposed between the curved surface of the light transmissive plate and the light modulating cell and attaches one side of the light modulating cell to the curved surface of the light transmissive plate.
