Abstract
A first integrated circuit disposed in a region, in which a length of a first space in a device depth direction is largest, among two regions dividing an entire region of a first main surface of a signal processing circuit board into two in a device width direction. The first space is a space between the signal processing circuit board and a metal chassis, which is a member of the metal chassis and a back cover that opposes the first main surface on which the first integrated circuit is mounted. A first heat sink is disposed between the metal chassis and the back cover and has a plurality of fins. A length of each of the plurality of fins in the device depth direction is set according to a length of the first space in the device depth direction at a position of the fin in the device width direction.
Claims7
A curved display device comprising:
- a display panel having a curved shape such that both end sides of the display panel in a device width direction of the curved display device protrude forward relative to a center side of the display panel;
- a chassis having a curved shape which approximately corresponds to the curved shape of the display panel, the chassis being disposed on a rear side of the display panel;
- a back cover having a curved shape which approximately corresponds to the curved shape of the chassis, the back cover being disposed, with an interval from the chassis in a device depth direction of the curved display device on a rear side of the chassis;
- a circuit board having a plate shape with a pair of main surfaces in parallel with each other, the circuit board being disposed in a space between the chassis and the back cover such that a direction perpendicular to the pair of main surfaces is in the device depth direction;
- a first circuit component, mounted on a first main surface of the pair of main surfaces of the circuit board, for driving the display panel;
- and
- a first heat sink for cooling the first circuit component,
- wherein in the device depth direction, a first portion of the space between the circuit board and one of the chassis and the back cover that opposes the first main surface on which the first circuit component is mounted,
- the first circuit component is disposed in a region, in which a length of the first portion of the space in the device depth direction is larger than at least one of a plurality of regions obtained by dividing an entire region of the first main surface of the circuit board into two or three regions in the device width direction,
- the first heat sink is disposed in the first portion of the space and has a plurality of fins each of which extends in the device depth direction,
- a length of each of the plurality of fins in the device depth direction is set according to a length of the first portion of the space in the device depth direction at a position of each of the plurality of fins in the device width direction, and
- an average length of the plurality of fins which overlay the first circuit component in the device depth direction is greater than an average length of the remaining plurality of fins which do not overlay the first circuit component in the device depth direction.
