A display apparatus and a method for controlling a display apparatus are provided. A display apparatus includes a display configured to display an image, a rotator configured to rotate the display, and a controller configured to control the rotator to rotate the display when a predetermined event occurs, and control the display to generate a plurality of screens on the rotated display, display a first image on one of the plurality of screens, and display at least one different image on another screen among the plurality of screens.

A waterproof display apparatus includes an envelope, a display panel and an adhesive structure. The envelope includes an inner enclosing surface. The inner enclosing surface defines an accommodating space. The display panel is at least partially accommodated in the accommodating space of the envelope. The envelope includes a light permeable portion that allows light from the display panel to travel out of the envelope. The adhesive structure is located in the accommodating space. The adhesive structure is adhered between the inner enclosing surface of the envelope and the display panel.

A display apparatus and a display device including the display apparatus are disclosed. The display apparatus includes a display panel, an elastic supporting backplate and at least one actuating structure; the display panel is attached to the supporting backplate; the actuating structure is arranged on one side of the supporting backplate away from the display panel and are in contact with the supporting backplate; and the supporting backplate is capable of being driven by the actuating structure, so that bending degrees of the supporting backplate and the display panel can be changed.

A device for protecting a television screen comprising having a mount wherein the mount is configured to engage the television; a cylinder configured to attach to the mount such that the cylinder will be positioned at the screen side of the television; and a protective material configured to coil around the cylinder, wherein the protective material is further configured to unravel over the television screen.

A display device includes a light source, a reflection sheet, a display panel and a display panel supporting member. The display panel supporting member is disposed on a back side of the display device relative to the reflection sheet. A part of a back surface of the display panel supporting member disposed on the back side of the display device relative to the reflection sheet forms a rear chassis. The display panel supporting member has a first recessed portion that is recessed toward the reflection sheet such that the first recessed portion presses an inner area of a back surface of the reflection sheet except for a vicinity of an outer peripheral portion of the back surface of the reflection sheet.

A small-spacing LED screen is provided, comprising a bottom case, an HUB board arranged on one side of the bottom case, and a small module arranged on the other side and electrically connected with the HUB board. The small module includes a module main body and a drive control unit which is electrically connected with the module main body to drive and control the module main body. An adaptor plate is also arranged between the small module and the HUB board. The HUB board is electrically connected with the adaptor plate. The drive control unit is arranged on the adaptor plate. The LED screen has the smallest spacing, and the reject ratio of the small module is greatly reduced.

The invention relates to switch mode power supply modules and items of equipment powered by these modules. The power supply module comprises circuits for cyclically interrupting the switching operation, during a so-called switching operation interruption phase, if the load current of the module is less than a current threshold value and sustaining the switching operation, during a so-called switching operation phase, if the load current is greater than the load current threshold value and circuits for ending the switching operation interruption phase if the power supply voltage of the item of equipment is greater than a voltage threshold value. The item of equipment powered by the module comprises a capacitive element able to store energy from the module during the switching operation phase and to release the energy stored between the output terminals of the power supply module when it receives an activation signal.

A display includes a display panel, a board mounting portion, and a circuit board arranged at one surface of the board mounting portion. The display panel also includes a cover portion positioned only at a portion of the one surface of the board mounting portion. The portion includes a region in which the circuit board is arranged. The cover portion includes a bottom surface portion and a first side surface portion that extends from the bottom surface portion toward the one surface of the board mounting portion. The first side surface portion includes a first opening portion.
