A curved surface display device and a curved surface display method, which belong to the field of display technology. The curved display device comprises a display panel, a motor, a first arc lever and a second arc lever. A first end of the first arc lever and the second arc lever are connected with the motor through a connector, and a second end of the first arc lever and second arc lever are connected with the casing of the device. The connector is used for pulling the first end of the first arc lever and the first end of the second arc lever with rotation of the motor, such that the first arc lever and the second arc lever rotate around their pivots respectively, thus realizing automatic bending of the casing, which meets the user's requirement of adjusting the curvature of the curved surface display device.

A base mounting assembly and a display device are provided. The base mounting assembly includes a main support on a side of a first device, a base including a pedestal part below the first device and a support post connected with the pedestal part and opposite to the main support, the support post including a first end away from the pedestal part and a second end connecting with the pedestal part, and a cushion block movably provided between the support post and the main support. A distance between the support post and the main support is gradually reduced from the first end to the second end so that when the cushion block is moved between the first end and the second end, a position of the support post relative to the main support is changed, causing a change of a position of the pedestal part relative to the first device.

A display device includes: a display unit that includes a display screen displaying an image, a first side extending in a long direction of the display unit, and a second side extending in a short direction of the display unit; a first presence sensor that is provided on the first side; a second presence sensor that is provided on the second side; a display screen detecting unit that detects whether the display screen of the display unit is in a vertical orientation or a horizontal orientation; and a control unit that obtains a detection result of either one of the first presence sensor and the second presence sensor in accordance with the orientation detected by the display screen detecting unit, the control unit controlling display of an image on the display unit based on the obtained detection result.

Embodiments of the present disclosure provide a wearable projection equipment, comprising a first structure body and a second structure body which are movably connected to each other, and the first structure body can rotate relative to the second structure body; and a projection device is respectively provided on the first structure and the second structure. The wearable projection equipment is capable of projecting images in different directions respectively, such that application scenarios of the wearable projection equipment become more extensive.

An upper guide and a lower guide are provided on an escutcheon integrally attached to the chassis. An upper movable pin engageable with and disengageable from the upper guide, a lower movable pin engageable with and disengageable from the lower guide, and a fulcrum switching mechanism that reciprocates the upper movable pin and lower movable pin in the left-right direction are attached to a display body disposed in front of the escutcheon. The fulcrum switching mechanism makes the rotational fulcrum of the display body switchable between a first pivoting state, in which the upper movable pin is engaged with the upper guide and the lower movable pin is disengaged from the lower guide, and a second pivoting state, in which the lower movable pin is engaged with the lower guide and the upper movable pin is disengaged from the upper guide.

A projection apparatus is provided, which includes a projector body, a first ultrasonic sensor and a second ultrasonic sensor. The projection apparatus is configured to project an image onto a screen. The first ultrasonic sensor and the second ultrasonic sensor are disposed on the projector body. The first ultrasonic sensor and the second ultrasonic sensor are respectively configured to measure a distance between the projector body and the screen. The projector body corrects the image in a horizontal direction through the first ultrasonic sensor and the second ultrasonic according to the measured distances. The first ultrasonic sensor and the second ultrasonic sensor are disposed on a first reference line corresponding to the first direction. The projection apparatus of the invention may provide good image quality.
