Abstract
A display apparatus includes a liquid crystal panel; a light source module configured to provide light to the liquid crystal panel; a printed circuit board (PCB) on which the light source module is mounted; and at least one chassis accommodating the liquid crystal panel and the PCB. The light source module includes: a substrate; a reflector positioned on the substrate, and including a curved surface having a shape resulting from rotating a portion of a parabola around a directrix of the parabola, the directrix perpendicular to the substrate; and a plurality of light sources mounted on the substrate along focal points of the parabola of the reflector.
Claims20
A display apparatus comprising:
- a liquid crystal panel;
- a light source module configured to provide light to the liquid crystal panel;
- a printed circuit board (PCB) on which the light source module is mounted;
- and
- at least one chassis accommodating the liquid crystal panel and the PCB,
- wherein the light source module comprises:
- a substrate;
- a reflector positioned on the substrate, and comprising a curved surface having a shape resulting from rotating a portion of a parabola around a directrix of the parabola, the directrix perpendicular to the substrate;
- a plurality of light sources mounted on the substrate along focal points of the parabola of the reflector;
- and
- a transmitting member that comprises a transparent material, the transmitting member positioned between the plurality of light sources and the reflector,
- wherein the light source module further comprises a reflection member positioned on a surface of the reflector, which is opposite to the curved surface of the reflector on which the transmitting member is positioned, the reflection member comprising a body having a greater refractive index than the transmitting member, and
- wherein the reflector, the plurality of light sources, the transmitting member, and the reflection member are in direct contact with a front surface of the substrate.
