Provided is an image display device that attains see-through characteristics and visual perceptibility with a simple structure.

An image display device includes a frame, a signal generation unit (light source unit) that generates signal light L1 that is a TE wave, a scan light emission unit that is provided with a light scan unit 42 (light scanner) that scans the signal light L1, a reflection unit 6 (reflecting optical unit) that reflects the signal light L1 scanned by the light scan unit 42; a diffracting optical unit 9 that includes a pair of diffraction gratings whose grating patterns are equivalent to each other and diffracts the signal light L1 reflected at the reflection unit 6; and a polarizing plate 8 (polarization selection unit) that is located at an opposite side in relation to the diffracting optical unit 9 with respect to the reflection unit 6 and allows outside-world light L2 that is a TM wave to pass toward the reflection unit 6, wherein the diffracting optical unit 9 diffracts the signal light L1 and does not diffract the outside-world light L2. The signal light L1 is split into plural beams at the diffracting optical unit 9 to enter the eye EY of a user.

A flat panel display device comprising a backboard and a display panel fitted therewith is provided. The edge of the backboard is structured as a barrier wall extending perpendicular to the body of the backboard. A stepped groove is arranged on the interior face of the barrier wall for supporting the display panel and forming accommodating space between the display panel and the body of the backboard. The stepped groove extends from an outer end of the barrier wall towards the body of the backboard, and the depth of the stepped groove is consistent with the thickness of the display panel. The backboard is made of plastic plate containing a enhancing element. The flat panel display device according to the present disclosure can be designed as a light and thin display device with no frame, and thus is suitable for making an all-in-one machine.

A display apparatus and a display method using the same are provided. The display apparatus includes a curved display, a guide member on which the curved display is mounted to slidably move and configured to provide a curved concave path formed with respect to a user, and a driver configured to move the curved display along the guide member. The guide member includes left and right frames vertically disposed at intervals, a lower rail of which both ends are coupled to lower ends of the left and right frames, and an upper rail of which both ends are coupled to upper ends of the left and right frames and which is parallel to the lower rail.

A display apparatus is provided. The display apparatus includes a display which is curved such that opposite lateral ends thereof protrude forward relative to a central portion thereof. A support frame having a lower end supported on a horizontal surface and allowing the display to be disposed inside thereof is provided; wherein the support frame is curved such that opposite lateral ends thereof protrude forward relative to the central portion thereof.

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.

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 device housing and corresponding receiving bracket may provide a snap-in or screwless configuration to place a monitor into a wall bracket or self-standing display housing. In one example the apparatus includes a display housing that includes an electronic display affixed to a mounting bracket which rests along the perimeter of the electronic display and which comprises at least two spring loaded securing tabs, and a receiving bracket configured to house the display housing and the mounting bracket in a secure position with at least two receiving slots form-fitted to receive the at least two spring loaded securing tabs and provide a secure spring loaded locking position that maintains the display device housing and the mounting bracket in a locked position.
