Abstract

The display system of the present invention includes: a body unit (1) for transmitting image data that has been generated; and a display device (2) for displaying an image in accordance with the image data that has been transmitted from the body unit (1), and said display system is characterized in that the body unit (1) and the display device (2) perform communications via radio communication means, and the body unit (1) and the display device (2) are separately providable. Thus, the radio transmission is used as communication means, and there is no cable, connecting the display device (2) and the body unit (1), that transfers the data signal, so that the device user can operate the system freely while watching the display device (2). As a result, it is possible to improve the workability of the user of the present display system. Further, since there is no wire connection section, using a connection clip, that is provided in a conventional display device, it is possible to simplify a mechanism for securing the strength of the wire connection section.

Claims

1. A display system including:

a body unit for transmitting display data that has been generated; and

a display device for performing display in accordance with the display data that has been transmitted from the body unit, wherein

the body unit and the display device perform communications via radio communication means, and the body unit and the display device are separately wearable,

the display device includes;

a receiving section for receiving the display data that has been transmitted from the body unit via the radio communication means,

a control section for providing a display signal to a display panel in accordance with the display data that has been received, and for controlling the receiving section, and

a transmitting section for causing the control section to evaluate a display condition of the display panel, so as to feedback an evaluation result to the body unit via the radio communication means,

the display data is transmitted from the body unit so as to be directly displayable in the display device without being stored in a frame memory in the display device, and

the body unit transmits the display data directly to the display device via radio communication.

2. The display system as set forth in claim 1, wherein the transmitting section transmits a predefined condition for performing display in the display panel to the body unit via the radio communication means.

3. The display system as set forth in claim 1, wherein a pixel array is provided on a surface of one of panels constituting the display panel, and the pixel array is constituted of a low temperature process polycrystal silicon TFT element.

4. The display system as set forth in claim 1, wherein the display panel itself includes a memory function.

5. The display system as set forth in claim 1, wherein the display device includes an operation unit, and operation content of the operation unit is transmitted via the radio communication means to the body unit.

6. The display system as set forth in claim 1, wherein the display device includes storage means for storing the display data.

7. The display system as set forth in claim 1, wherein the control section detects a power capacity of a driving power source so as to transmit power capacity information to the body unit, and the body unit determines an amount of the display data that is to be transmitted to the display device, in accordance with the power capacity information.

8. The display system as set forth in claim 1, wherein the radio communication means is constituted in accordance with specifications of Bluetooth.

9. A display system including:

a body unit for generating display data; and

a display device for displaying the display data, wherein

the body unit and the display device are separated from each other,

the body unit and the display device are connected to each other by radio communication means,

the body unit transmits the display data directly to the display device by the radio communication means, and

the display device includes;

a display panel for displaying the display data, and a transmitting section for transmitting a display condition of the display panel or a predefined condition for performing display via radio transmission,

a receiving section for receiving the display data that has been transmitted from the body unit via the radio communication means,

a control section for providing a display signal to the display panel in accordance with the display data that has been received, and for controlling the receiving section, and

a transmitting section for causing the control section to evaluate the display condition of the display panel or the predefined condition, so as to feedback an evaluation result to the body unit via the radio communication means,

wherein the display condition or the predefined condition is transmitted from the display device to the body unit.

10. The display system as set forth in claim 9, wherein the radio communication means is constituted in accordance with specifications of Bluetooth.

11. A display device including a display panel for displaying display data, said display device comprising:

a receiving section for receiving the display data displayed in the display panel via radio transmission;

a control section for providing a signal to the display panel in accordance with the display data that has been received, and for controlling the receiving section an operation unit by which device a user inputs data, wherein the display device receives a control signal directly from the operation unit; and

a transmitting section for transmitting a display condition of the display panel or a predefined condition for performing display via radio transmission, and for causing the control section to evaluate the display condition or the predefined condition, so as to feedback an evaluation result to the body unit via the radio transmission,

wherein the display condition or the predefined condition is transmitted from the display device to a body unit, and the body unit transmits the display data directly to the display device via radio transmission.

12. The display device as set forth in claim 11, wherein an operation condition of the operation unit is displayed on a screen of the display device.

13. The display device as set forth in claim 11, wherein the control section detects a power capacity of the display device, so as to transmit information of the power capacity that has been detected, via the radio transmission.
