Abstract
An image display device includes a rear cover to receive a display panel. The rear cover is provided with a deformation alleviating portion that deforms due to expansion of a surrounding portion caused by thermal stress. The deformation alleviating portion reinforces the rear cover and prevents thermal deformation of the rear cover, enabling realization of a slim image display device.
Claims16
An image display device comprising a cover on which a display panel to form an image is disposed,
- wherein the cover comprises a base comprising a plurality of deformation alleviating portions that deforms in response to a variation in size of the base caused by thermal stress and are spaced apart from one another,
- wherein each of the plurality of deformation alleviating portions comprises:
- an outermost edge;
- and
- a concave surface portion provided on an inner side of the outermost edge, and
- wherein the outermost edge of the each of the plurality of deformation alleviating portions forms a circle.
An image display device comprising:
- a liquid crystal display panel;
- a backlight unit configured to emit light to the liquid crystal display panel;
- and
- a cover comprising a base on which the backlight unit is disposed,
- wherein the base comprises a plurality of deformation alleviating portions that deform to compensate for a variation in size of the base caused by thermal stress and are spaced apart from one another,
- wherein each of the plurality of deformation alleviating portions comprises:
- an outermost edge;
- and
- a concave surface portion provided on an inner side of the outermost edge, and
- wherein the outermost edge of the each of the plurality of deformation alleviating portions forms a circle.
An image display device comprising:
- a display panel to form an image;
- and
- a cover comprising a plurality of deformation portions configured to deform in a direction away from the cover in response to an increased size of a surrounding portion caused by thermal stress and spaced apart from one another,
- wherein each of the plurality of deformation alleviating portions comprises:
- an outermost edge;
- and
- concave surface portion provided on an inner side of e outermost edge, and
- wherein the outermost edge of the each of the plurality of deformation alleviating portions forms a circle.
A method of forming a cover of an image display device, the method comprising:
- Pressing a surface of a die onto a first surface of a base of the cover to form each of a plurality of concave portions spaced apart from one another on the base, the surface of the die corresponding to an outermost edge of the each of the plurality of concave portions;
- pressing the surface of the die onto a second surface of the base opposite to and facing the first surface of the base against the concave portions to deform the concave portions.
