Abstract

A multi-view display device display images based on received image signals, received request signals, and transmits timing control signals. When the device receives request signals with distinct channel information during a given period, the device displays a first image signal and transmits a first timing control signal that includes one of the distinct channel information during a first period of an image frame, and displays a second image signal and transmits a second timing control signal that includes the other of the distinct channel information during another second period of the image frame. User controllers having glasses are activated or deactivated to view or obscure the displayed images based on receipt of the timing control signals.

First claim

What is claimed is:

1. A multi-view display device, comprising:
a display panel configured to display images based on received image signals;
a signal receiving unit configured to receive request signals including channel information;
a signal transmitting unit configured to transmit timing control signals;
a signal controller configured to receive the request signals from the signal receiving unit and output the image signals to the display panel,
wherein when the signal controller receives at least two of the request signals with distinct channel information during a given period, the signal controller:
outputs a first image signal to the display panel for view by a first user controller and a first timing control signal to the signal transmitting unit that includes one of the distinct channel information during a first period of an image frame; and
outputs a second image signal to the display panel for view by a second user controller and a second timing control signal to the signal transmitting unit that includes the other of the distinct channel information during another second period of the image frame,
wherein the first user controller is configured to enable a user to stop watching before the end of the first period of the image frame and the second user controller is configured to enable a user to stop watching before the end of the second period of the image period.

2. The multi-view display device of claim 1 , further comprising the user controllers, each user controller comprising:
polarized glasses;
a second signal transmitter to transmit one of the at least two request signals; and
a second signal receiver configured to receive the timing control signals,
wherein the corresponding user controller is configured to activate the polarized glasses during one of the two periods to view the display panel and deactivate the polarized glasses to prevent viewing of the display panel during the other period based on the received timing control signals.

3. The multi-view display device of claim 2 , wherein the channel information is identification ID information that distinguishes the user controls from one another.

4. The multi-view display device of claim 3 , wherein the ID information of the first user controller is a first pulse width in the request signal from the first user controller, wherein the ID information of the second user controller is a second pulse width in the request signal from the second user controller, and the first and second pulse widths differ from one another.

5. The multi-view display device of claim 3 , wherein the ID information of the first user controller is a first number of pulses in the request signal from the first user controller, wherein the ID information of the second user controller is a second number of pulses in the request signal from the second user controller, and the first and second numbers differ from one another.

6. The multi-view display device of claim 3 , wherein the ID information of the first user controller is a first bit pattern in the request signal from the first user controller, wherein the ID information of the second controller is a second bit pattern in the request signal from the second user controller, and the first and second bit patterns differ from one another.

7. The multi-view display device of claim 3 , wherein each user controller comprises a switching circuit and a setting of each switching circuit corresponds to the respective ID information.

8. The multi-view display device of claim 7 , wherein each switching circuit includes a number of selectable buttons, and the selections of the buttons correspond to the respective ID information.

9. The multi-view display device of claim 2 , wherein each user controller is configured to send a determination signal through the second signal transmitting unit that indicates a request for one of a 2D image and a 3D image.

10. The multi-view display device of claim 2 , wherein the signal receiving unit receives the determination signal and forwards the determination signal to the signal controller.

11. The multi-view display device of claim 10 , wherein the signal controller formats the image signals sent to the display panel as 2D image signals when the received determination signal indicates a request for a 2D image and formats the images signals as 3D images when the received determination signal indicates a request for a 3D image.

12. The multi-view display device of claim 1 , wherein the signal receiving unit and the signal transmitting unit are both located within the display panel.
