Abstract

A display unit includes: a display section having a plurality of light-emitting devices arranged in a straight line; a driving section supplying a display driving signal for controlling the luminance of each of the light-emitting devices; and a display control section connected to the driving section for supplying the driving section with either a first display control signal for controlling the luminance of the light-emitting devices to display a preset display pattern according to an operation control signal from a controller or a second display control signal for controlling the luminance of the light-emitting devices in synchronism with the level of an audio signal, wherein the first display control signal is generated based on a wave function.

First claim

What is claimed is:

1. A display unit comprising:
a display section having a plurality of light-emitting devices arranged in a straight line;
a driving section supplying a display driving signal for controlling the luminance of each of the light-emitting devices;
a receiving section configured to receive a remote control signal from a remote controller; and
a display control section connected to the driving section and configured to supply the driving section with a selected display control signal of a first display control signal for controlling the luminance of the light-emitting devices to display a preset display pattern according to an operation control signal from a controller and a second display control signal for controlling the luminance of the light-emitting devices in synchronism with the level of an audio signal,
wherein one of the first display control signal and the second display control signal is superimposed on a third display control signal based on the received remote control signal, and
wherein, the first display control signal is generated based on a wave function describing motion of a liquid.

2. A display unit according to claim 1 , wherein the second display control signal controls the luminance based on a model in which a plurality of points are connected with each other by a spring and suspended in a vertical direction, the plurality of points being controlled by causing an uppermost point to be displaced upward by a force according to an amount of energy of the audio signal or a change in the amount of energy, thereby setting a magnitude of a resultant displacement of each of the plurality of points as the luminance of the point.

3. A display unit according to claim 2 , wherein a spring coefficient of the spring can be changed.

4. A display unit according to claim 1 , wherein the second display control signal is selected in an event the audio signal is present.

5. A display unit according to claim 1 ,
wherein, the third display control signal for controlling the luminance of the light-emitting devices is generated to display another preset display pattern when the remote control signal is received
from the remote controller.

6. A display unit according to claim 1 , wherein an emission level table provides a set of control signals for controlling the luminance of each of the plurality of light-emitting devices on a predetermined cycle.

7. The display unit according to claim 1 , wherein the first display control signal is selected in response to an apparatus comprising the display unit being turned on.

8. A display unit according to claim 1 , wherein the first display control signal is generated such that the luminance of the light emitting devices varies according to a numerical value read from an emission level table, the numerical value being obtained by simulating the wave function describing the motion of the liquid.

9. An audio reproduction apparatus, comprising:
a display having a plurality of light-emitting devices arranged in a line;
a driver configured to supply a display driving signal for controlling the luminance of each of the light-emitting devices;
a receiver configured to receive a remote control signal from a remote controller;
a display controller connected to the driver and configured to supply the driver with a display control signal to control the luminance of the light-emitting devices to display a preset display pattern, wherein the display control signal is generated based on a wave function describing motion of a liquid, and
wherein the display control signal is superimposed on another display control signal based on the received remote control signal.

10. The audio reproduction apparatus according to claim 9 , wherein
the driver is supplied with the display control signal to control the luminance of the light-emitting devices to display the preset display pattern in response to the audio reproduction apparatus being turned on.

11. The audio reproduction apparatus according to claim 9 , wherein the display controller is further configured to control the luminance of the light-emitting devices in synchronism with an audio signal.

12. The audio reproduction apparatus according to claim 9 , wherein the other display control signal is generated to control the luminance of the light-emitting devices to display another preset display pattern.

13. A reproduction method, comprising:
receiving a remote control signal from a remote controller; and
supplying a display driving signal for controlling a luminance of a plurality of light-emitting devices based on a display control signal, the display control signal controlling the plurality of light emitting devices to display a preset display pattern, wherein the display control signal is generated based on a wave function describing motion of a liquid, wherein the luminance of the light-emitting devices is controlled in synchronism with an audio signal, and wherein the display control signal is superimposed on another display control signal based on the received remote control signal.

14. The reproduction method according to claim 13 , wherein the other display control signal is generated to control the luminance of the light-emitting devices to display another preset display pattern.
