A controller (101) of the display device (10) can adjust a gamma parameter when the temperature of a display module (102) is high, so as to reduce a drive voltage required by the display module (102) while keeping a brightness change of the display module (102) small. In this manner, the temperature of the display module (102) can be reduced, the display module (102) can be prevented from being damaged, and the display device (10) has a high reliability.

A flexible display device and an electronic device are provided. The flexible display device includes a display substrate, a polarizer and a first optical adhesive layer that are sequentially stacked, and is provided with a display area and a first corner area. In the first corner area, an outer contour of the polarizer and/or an outer contour of the first optical adhesive layer extend(s) beyond an outer contour of the display substrate. The display substrate includes an anti-crack base, an anti-crack retaining wall, and a plurality of anti-crack blocks that are at least located in the first corner area. The anti-crack retaining wall is formed on the anti-crack base and located outside of the display area, and the plurality of anti-crack blocks are formed on the anti-crack base and located on the side of the anti-crack retaining wall away from the display area.

According to an example embodiment of the present disclosure, an electronic device includes a display that is flexible, has at least a portion located at a first side of the electronic device, and is changeable in size to which the display is exposed to the first side, and a controller configured to display first content in at least a portion of the first side. In response to a first input, the controller displays a first portion of the first content in a first area of the first side and displays a second area distinguished from the first area.

A speaker and an electronic device are provided. The speaker includes a counterweight body, and a lower shell, a middle shell, an electric vibration plate, and a dome where the lower shell, the middle shell, and the electric vibration plate are matched to form an accommodating cavity, and the counterweight body is disposed in the accommodating cavity and is connected to a first surface of the electric vibration plate; the dome is disposed on a second surface of the electric vibration plate away from the counterweight body; and when a voltage is applied to the electric vibration plate, the electric vibration plate drives the dome to move.

The present invention relates to a near-eye display device. The a near-eye display device includes a display, a first lens disposed in front of the display so as to be spaced apart from the display by a predetermined distance, a dynamic aperture adjustment element disposed adjacent to the first lens to dynamically control an aperture size of the first lens and a horizontal position of the aperture on a plane perpendicular to an optical axis, a main optics lens disposed to be spaced apart from the first lens by a predetermined distance, and a control system configured to control the dynamic aperture adjustment element.

A head-mounted device includes a first light field camera, a second light field camera, a first light field display, a second light field display and a supporting structure. Each of the first light field camera and the second light field camera includes, in order from an object side to an image side, a lens group, a collimator and an image sensor. Each of the lens groups includes a plurality of lens units. The lens units are arranged in a two-dimensional lens array, and each of the lens units includes a lens container and a plurality of lens elements. A first engaging structure is disposed between at least two adjacent lens elements of the lens elements.

A hinge assembly includes: a fixed supporting piece; a rotating assembly, movably connected with the fixed supporting piece and including a first limiting portion; and a locking mechanism, disposed on the fixed supporting piece and including a limiting piece which includes a second limiting portion matched with the first limiting portion. The fixed supporting piece slides relative to the rotating assembly in a direction perpendicular to an axial direction of the rotating assembly in a rotation process of the rotating assembly, so that the first limiting portion is connected with the second limiting portion or the first limiting portion is separated from the second limiting portion; when the first limiting portion is connected with the second limiting portion, the two limiting portions are matched with each other to limit rotation of the rotating assembly; when separated, limiting of the rotating assembly is released.

A foldable display device may have housing portions coupled by a hinge. The hinge may have a series of interconnected links. The links may be formed from interdigitated fingers in a friction clutch. The fingers or other portions of the links may be provided with crescent-shaped slots that receive pins. During folding of the device, the pins may slide along the crescent-shaped slots, thereby ensuring that adjacent links rotate relative to each other about a rotation axis that lies outside of the hinge and within a flexible display panel. Links may also be formed from link members with curved mating bearing surfaces that slide relative to each other as adjacent links are rotated relative to each other. A housing rotation synchronization mechanism may be formed using a set of gears that extends between the first and second housing portions.

A display device which includes a display panel and a protection member above the display panel. The protection member may include an adhesive layer above the display panel, a first protection layer above the adhesive layer, and a second protection layer between the first protection layer and the adhesive layer. The first protection layer may have a first thickness and a first modulus, and the second protection layer may have a second thickness less than the first thickness and a second modulus less than the first modulus. The minimum value of the second thickness may be 20 μm, and the maximum value of the second thickness may satisfy Equation (1) below. The display device, which includes the protection member including the second protection layer satisfying Equation (1), may improve impact resistance and maintain reliability.
