Provided is a bendable television. The A bendable television includes a television body, an airbag, and an inflation and deflation mechanism. The television body has a flat state and a curved state. The airbag is bonded to a rear sidewall of the television body, and one side of the airbag away from the television body is provided with a deformation slot extending along a width direction of the airbag. The inflation and deflation mechanism is connected to the airbag, and is configured to inflate the airbag or draw gas out of the airbag. The television body is configured to change from the flat state to the curved state when the inflation and deflation mechanism inflates the airbag.

A display device according to the present technology includes: a plurality of linear portions that, when three directions orthogonal to each other are a first direction, a second direction, and a third direction, extends in the first direction and is positioned apart from each other in the second direction; and a connecting portion that connects respective parts of two linear portions adjacent to each other in the second direction. The linear portion and the connecting portion are integrally formed by injection molding, the linear portion has a base extending in the first direction and a pair of protrusions protruding in the third direction from both end portions of the base in the second direction, and both end portions of the connecting portion are continuous to respective tip portions of the protrusions of the two adjacent linear portions.

A light-transmitting assembly of a display device, a signal indicator, and the display device are provided in the embodiments of the present disclosure. The light-transmitting assembly of the display device includes: a light-transmitting adjustment member including a plurality of first patterns, a light transmittance of each first pattern is less than a light transmittance of a region of the light-transmitting adjustment member other than the first pattern, and each light-shielding area ratio of the first patterns is a ratio of a sum of areas of all the first patterns in any one region of the light-transmitting adjustment member to an area of the any one region.

Disclosed by the present application are a laser projection device and projection display method thereof, belonging to the technical field of laser projection. The laser projection device may comprise: a light source, a light modulation device, and a projection lens. The light source is used for providing an illumination beam. The light modulation device is used for modulating the illumination beam, at least two illumination beams being incident on at least two light-reflecting surfaces of the light modulating device, the light-reflecting surface types of the at least two light-reflecting surfaces being different, and the at least two illumination beams after modulation being of different light intensity; the projection lens is used for projecting the modulated illumination beam for imaging. The described laser projection device improves the display of the projected image.

The present invention relates to a lightweight, cost-effective and foldable screen shield for use with a portable electronic device. The shield has a back portion that is secured to the back of the screen, a top portion that lies horizontally above the screen to protect the screen from light and a pair of side panels covering the screen from side edges. The side panels and the top portion are collapsible, and can be secured with a pair of elastic straps or other fastener. The elastic straps are used for securing the shield device to the bezel or frame in an unfolded orientation, thereby allowing a secure attachment. The top section can be expanded and two side panels are pulled outward from the longitudinal edges. The top section and side panels form a three-sided barrier around the screen to block glare.
