A light guide body includes: a light incident portion on which light is incident; a light guiding portion which is adapted to guide the light incident on the light incident portion; and a light emitting portion which is adapted to emit the light guided by the light guiding portion. One of the light incident portion and the light guiding portion is extended in a first direction, and the light emitting portion is extended in a second direction which is perpendicular to the first direction.

A direct-lit type backlight source includes a backplate and a point light source array disposed on the backplate. A light output shape of a first optical lens employed by each of point light sources of corner regions of the point light source array and that of a second optical lens employed by each of a plurality of point light sources of the non-corner region are different. For instance, the light output shape of the first optical lens is symmetrical in a first direction and asymmetrical in a vertical second direction. Moreover, a liquid crystal television adopting the direct-lit type backlight source is provided. The light-output shape of the optical lens adopted by each of the point light sources of the respective corners is designed to illuminate the corners uncovered by light source in the prior art, which can improve optical uniformity of the corners.

A method for designing a display panel. The method includes calculating, for each of a plurality of viewing locations, a difference value between a right side viewing angle of that viewing location and a left side viewing angle of that viewing location, the calculating is performed for each of a plurality of curvatures, and setting, from among the plurality of curvatures, a curvature of the curved display panel based on the difference values. Accordingly, a curved display panel which enlarges a viewing angle of a viewer than a flat display panel, increases an immersion, and decreases a distortion of a viewing angle may be realized.

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 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.

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.

The present invention provides methods and systems for a television protection and carrying device that includes a top portion with a base portion, a first end, a second end, and two sides. A bottom portion with a first end, a second end and two sides, and a support device pivotally connected to the top portion having a first position and a second position, wherein the first position the support device is adjacent the top portion and in the second position is spaced-apart from the top portion for positioning the top portion in the vertical position.
