Abstract
A display apparatus includes: a display panel; a light guide plate disposed behind the display panel; a printed circuit board; a heat radiator disposed on the printed circuit board and configured to radiate heat; and a plurality of light source packages disposed on the printed circuit board and configured to supply light to the light guide plate, each light source package of the plurality of light source packages including: a light source configured to generate the light; a light converter configured to convert properties of the light generated by the light source, and a package housing in which the light source is installed, the package housing being disposed on the printed circuit board and in contact with the light converter to transfer heat from the light converter to the heat radiator.
Claims20
A display apparatus comprising:
- a display panel;
- a light guide plate disposed behind the display panel;
- a printed circuit board;
- a heat radiator disposed on the printed circuit board and configured to radiate heat;
- and
- a plurality of light source packages disposed on the printed circuit board and configured to supply light to the light guide plate, each light source package of the plurality of light source packages comprising:
- a light source configured to generate the light;
- a light converter configured to convert properties of the light generated by the light source, and
- a package housing in which the light source is installed, the package housing being disposed on the printed circuit board and in contact with the light converter to transfer heat from the light converter to the heat radiator.
A display apparatus comprising:
- a display panel;
- a light guide plate disposed behind the display panel;
- a first printed circuit board;
