Abstract

According to one embodiment, a display apparatus includes a display panel, a light emitting element arranged as a light source for the display panel, a board on which a first circuit for controlling power supply to the light emitting element is arranged, and a second circuit which is arranged on the board, and executes a process unrelated to a drive process of the display panel.

Claims

1. A display apparatus comprising:

a display panel;

a light emitting element arranged as a light source for the display panel;

a board on which a first circuit for controlling power supply to the light emitting element is arranged; and

a second circuit which is arranged on the board, and executes a process unrelated to a drive process of the display panel.

2. An apparatus according to claim 1, which further comprises an interface configured to be connected to an external device, and in which the second circuit is connected to the interface.

3. An apparatus according to claim 2, wherein the second circuit includes one of a circuit for processing a sound signal, a circuit for controlling a USB power supply, and a circuit for processing an image signal.

4. An apparatus according to claim 1, further comprising a controller which is arranged on the board, and controls at least one of the first circuit and the second circuit.

5. An information processing apparatus comprising:

a main body which incorporates a first board; and

a display unit arranged to be pivotal with respect to the main body,

the display unit further comprising

a display panel,

a light emitting element arranged as a light source for the display panel,

a second board on which a first circuit for controlling power supply to the light emitting element is arranged, and

a second circuit which is arranged on the second board, is connected to a circuit arranged on the first board, and executes a process unrelated to a drive process of the display panel.

6. An apparatus according to claim 5, wherein the display unit further comprises an interface configured to be connected to an external device, and

the second circuit is connected to the interface.

7. An apparatus according to claim 5, wherein the display unit further comprises an interface configured to be connected to an external device, and

the interface inputs a signal transmitted to a circuit on the first board via the second circuit, or outputs a signal transmitted from the circuit on the first board via the second circuit.

8. An apparatus according to claim 5, wherein the second circuit includes one of a circuit for processing a sound signal, a circuit for controlling a USB power supply, and a circuit for processing an image signal.

9. An apparatus according to claim 5, which further comprises a hinge mechanism which connects the main body to the display unit, and in which the second circuit is connected to a circuit on the first board via the hinge mechanism.

10. An apparatus according to claim 5, further comprising a controller which is arranged on the second board, and controls at least one of the first circuit and the second circuit.
