Abstract
The light guide plate includes a plurality of prism grooves recessed in a triangular groove shape on the entire surface of the light guide plate. The light guide plate includes a light guide plate, Most of the light incident on the display panel is emitted to the front side again via the exhibition room located on the rear side by the prism grooves so that the exhibition room can be illuminated with the light source used in the display panel and the additional light source for illuminating the display can be eliminated , The showcase can be made thinner.
Description
The present invention relates to a show case used for displaying a product.
In general, showcases are used to display various exhibits.
Such a show case includes a housing that forms an exhibition room in which an exhibition is held, a transparent plate such as tempered glass that covers the front of the housing, and a light source that generates light, , And to be able to see the exhibit from the outside better.
In recent years, there has been a show case in which a display panel made of a liquid crystal panel or the like is arranged in place of a transparent plate so that an image can be seen together with an exhibit.
One aspect of the present invention is to provide a showcase which is made thinner.
A showcase according to an aspect of the present invention includes a light guide plate disposed on a front side of an object to be displayed, and a light source disposed opposite to at least one of four sides of the light guide plate, wherein the light guide plate has a triangular groove shape And a plurality of prism grooves provided concavely in the circumferential direction.
The light source includes a pair of light sources corresponding to the left and right sides of the light guide plate, and the prism grooves are formed in an isosceles triangle shape in which the two hypotenuses correspond to the left and right sides of the light guide plate.
In addition, the apex angle of the prism grooves is formed at an angle of 80 degrees or more and 140 degrees or less.
In addition, the length of the hypotenuse of the prism grooves is formed to be 50 mu m or less.
The light source includes a substrate extending to correspond to one side of the light guide plate, and a plurality of light emitting diodes disposed on the substrate.
In addition, the size of the prism groove provided in a portion adjacent to the light source is smaller than the size of the prism groove provided in a portion apart from the light source.
In addition, a gap between the prism grooves provided at a portion adjacent to the light source is formed to be larger than a gap between the prism grooves provided at a portion apart from the light source.
The display device further includes a display panel disposed on the front side of the light guide plate.
The display device further includes a housing disposed on a rear side of the light guide plate to form an exhibition room in which an exhibition to be displayed is received.
According to another aspect of the present invention, there is provided a showcase comprising a display module, and a housing disposed on a rear side of the display module and having an exhibition room accommodated therein, the display module including a display panel, And a light source disposed opposite to at least one of the upper, lower, right, and left sides of the light guide plate. The light guide plate includes a plurality of prism grooves recessed in a triangular groove shape on the entire surface thereof.
The display module includes a middle mold for supporting the display panel, a front chassis coupled to a front side of the middle mold to maintain the display panel installed in the middle mold, And a rear chassis coupled to the rear side of the middle mold, wherein the middle mold, the front chassis, and the rear chassis are each formed into a square ring shape so that light can pass therethrough.
As described above, the showcase according to the present invention includes a light source corresponding to the side surfaces of the light guide plate and the light guide plate, and the prism grooves are provided on the front surface of the light guide plate, so that most of the light incident into the light guide plate from the light source is located on the rear side The display room can be illuminated through the light source used in the display panel, so that the additional light source for illuminating the display can be eliminated, and the showcase can be made thinner.
