BACKGROUND

1. Field

The present disclosure relates to a display apparatus and more particularly, to a display apparatus having a thin thickness, and a light source module thereof.

2. Description of Related Art

Generally, a display apparatus converts obtained or stored electrical information into visual information and displays the visual information to a user. The display apparatus is used in various fields such as home or workplace.

The display apparatus includes a monitor apparatus connected to a personal computer or a server computer, a portable computer device, a navigation terminal device, a general television apparatus, an Internet Protocol television (IPTV), a portable terminal device, such as a smart phone, a tablet PC, a personal digital assistant (PDA) or a cellular phone, various display apparatuses used to reproduce images, such as advertisements or movies in an industrial field, or various kinds of audio/video systems.

The display apparatus includes a light source module configured to convert electrical information into visual information, and the light source module includes a plurality of light sources configured to independently emit light. Each of the plurality of light sources includes, for example, a light emitting diode (LED) or an organic light emitting diode (OLED). For example, the LED or the OLED may be mounted on a circuit board or a substrate.

Recently, display apparatuses have become thinner and thinner. In order to provide a thin display apparatus, a light source module must also become thinner. Because a thickness of the light source module is reduced, a light source may be miniaturized and the number of light sources disposed in the light source module may be increased. The miniaturization of the light source and the increase in the number of light sources may cause optical defects (for example, unevenness) of the light source module.

SUMMARY

The present disclosure is directed to providing a display apparatus capable of preventing or suppressing an optical defect (for example, unevenness).

According to one or more embodiments, a display device is provided. The display device includes a liquid crystal panel; a plurality of light sources configured to emit blue light; a reflective sheet including four edge portions and a center portion, wherein a plurality of holes are disposed on the reflective sheet, the plurality of holes includes a first hole and a second hole on each of the four edge portions of the reflective sheet, each of the four edge portions includes an edge of the reflective sheet, the first hole is disposed at a first distance from the edge of the reflective sheet, and the second hole is disposed at a second distance from the edge of the reflective sheet, wherein the second distance is greater than the first distance; and a plurality of light conversion dots including a plurality of first light conversion dots and a plurality of second light conversion dots, wherein the plurality of first light conversion dots are disposed around the first hole of the reflective sheet, and the plurality of second light conversion dots are disposed around the second hole of the reflective sheet, wherein the plurality of holes further includes other holes disposed on the center portion, no light conversion dot is disposed around each of the other holes, and wherein the plurality of light conversion dots comprise at least one of a fluorescent material, a dye, or a pigment.

According to one or more embodiments, a light apparatus for a display device is provided. The light apparatus includes a reflective sheet including four edge portions and a center portion, wherein a plurality of holes are disposed on the reflective sheet, the plurality of holes includes a first hole and a second hole on each of the four edge portions of the reflective sheet, each of the four edge portions includes an edge of the reflective sheet, the first hole is disposed at a first distance from the edge of the reflective sheet, and the second hole is disposed at a second distance from the edge of the reflective sheet, wherein the second distance is greater than the first distance; and a plurality of light conversion dots including a plurality of first light conversion dots and a plurality of second light conversion dots, wherein the plurality of first light conversion dots are disposed around the first hole of the reflective sheet, and the plurality of second light conversion dots are disposed around the second hole of the reflective sheet, wherein the plurality of holes further includes other holes disposed on the center portion, no light conversion dot is disposed around each of the other holes, and wherein the plurality of light conversion dots comprise at least one of a fluorescent material, a dye, or a pigment.

A display apparatus according to an aspect of the present disclosure may prevent or suppress an optical defect (for example, uneveness).
