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.

Provided is a display device including an image display unit configured to display an image with a plurality of pixels arranged on a display surface, an eyepiece optical unit configured to project the display surface of the image display unit in a manner that a predetermined angle of view is obtained, and an image correction unit configured to correct a display image on the display surface at a position of each of representative pixels which are discretely located on the display surface, on the basis of distortion generated due to the eyepiece optical unit.

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.

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.

Left and right sides in the television are provided symmetrically with independent sound boxes. Each sound box comprises a box body and a loudspeaker group, a front passive radiator and a rear passive radiator that are located in the box body. The front passive radiator is installed on the front box wall of the box body. The loudspeaker group installed on the front box wall is disposed on one side or left and right sides of the front passive radiator. The rear passive radiator is installed on the rear box wall, opposite to the front box wall, of the box body, and the rear passive radiator corresponds to the front passive radiator. The bass vibrating membrane area is exponentially increased through dual membrane symmetric resonance; and through the resonance, the bass effects are dramatically enhanced, the perfect reproduction of the whole tone frequency domain is achieved.

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.
