This invention relates to a comparatively light-weighted thin image display apparatus which uses a thin display panel such as an organic electroluminescence display panel or a liquid crystal display panel.
2. Description of the Related Art
A planar type display apparatus which is suspended on the ceiling is in the past known and disclosed in Japanese Patent Laid-Open No. 2002-32033.
SUMMARY OF THE INVENTION
Where it is tried to suspend a thin image display apparatus on the ceiling or the like so that a user can enjoy an image on the thin image display apparatus, it is necessary to connect some cable or an antenna line connected to a receiver antenna to the suspended thin image display apparatus in order to transmit an image signal to the thin image display apparatus. Therefore, apparently miscellaneous wiring lines may be required and deteriorate a fine sight. Also the arrangement location of the thin image display apparatus is restricted disadvantageously.
On the other hand, where a receiver antenna is directly built in the suspended thin image display apparatus, due to the property of the thin image display apparatus that it is installed indoors, the thin image display apparatus sometimes fails to receive an image signal because of a variation of the sensitivity which depends upon the position of the receiver antenna. Therefore, the suspended thin image display apparatus is disadvantageous in that the arrangement location thereof is restricted.
Therefore, it is demanded to provide a thin image display apparatus which may not require apparently miscellaneous wiring lines and can be installed while providing a fine sight. Also it is demanded to provide a thin image display apparatus which can receive an image signal even if the sensitivity varies depending upon the position of a receiver antenna and is free from restriction of the installation location.
According to an embodiment of the present invention, there is provided a thin image display apparatus including a thin image display apparatus body, a hollow support member having a first end at which the hollow support member supports the thin image display apparatus body through a rocking mechanism section and a second end at which a plug element configured to engage with an illumination apparatus wiring member attached to the ceiling or a wall is provided, and a power line extending through the hollow support member and configured to connect the plug element and the thin image display apparatus body to each other, the thin image display apparatus body receiving, when the plug element engages with the illumination apparatus wiring member, power supplied through the power line together with a modulated image signal supplied through the power line such that an image based on the modulated image signal is displayed on the thin image display apparatus body.
According to another embodiment of the present invention, there is provided a thin image display apparatus including a thin image display apparatus body configured to receive a modulated image signal transmitted by radio transmission from a receiver apparatus provided separately, a hollow support member having a first end at which the hollow support member supports the thin image display apparatus body through a rocking mechanism section and a second end at which a plug element configured to engage with an illumination apparatus wiring member attached to the ceiling or a wall is provided, and a power line extending through the hollow support member and configured to connect the plug element and the thin image display apparatus body to each other, the thin image display apparatus body receiving, when the plug section engages with the illumination apparatus wiring device, power supplied through the power line, receiving the modulated image signal transmitted by radio such that an image based on the modulated image signal is displayed on the thin image display apparatus body.
With the thin image display apparatus, power is supplied through the power line disposed in the inside of the support member and an image signal is supplied through the power line or by radio communication. Therefore, the thin image display apparatus do not become apparently miscellaneous and can be installed while keeping a fine appearance.
Further, with the thin image display apparatus, an image signal is supplied from the reception apparatus, which is provided separately from the thin image display apparatus body, through the power line or by radio communication. Therefore, there is no restriction to wiring, and a receiver antenna can be placed at a position at which it exhibits a high sensitivity. Consequently, there is no disadvantage by failure of reception of an image signal, and there is no restriction to the arrangement location of the thin image display apparatus body.
The above and other features and advantages of the present invention will become apparent from the following description and the appended claims, taken in conjunction with the accompanying drawings in which like parts or elements denoted by like reference symbols.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1A to 7, there is shown a thin image display apparatus to which the present invention is applied.
The thin image display apparatus is generally configured such that a thin image display apparatus body is suspended on the ceiling using a support member and power is supplied to the thin image display apparatus body through a power line disposed in the inside of the support member and also an image signal is supplied through the power line.
Referring first to FIGS. 1A to 1D, the thin image display apparatus shown includes a thin image display apparatus body 1 of a comparatively small thickness which uses a comparatively light-weighted thin display panel such as an organic electroluminescence display panel or a liquid crystal display panel. The front face of the thin image display apparatus body 1 includes an image display section 1a and a framework 2 surrounding the image display section 1a as seen in FIG. 1A.
The rear face of the thin image display apparatus body 1 is shown in FIG. 1B. Referring to FIG. 1B, the rear face of the thin image display apparatus body 1 has a driving display circuit accommodation section 3 provided at an upper portion of a central portion of the rear face thereof and covering such a driving display circuit as shown in FIG. 7 hereinafter described for displaying an image on the image display section 1a. A heat radiating opening 4 in the form of a slit for radiating heat generated from the driving display circuit therethrough is provided at an upper portion of the driving display circuit accommodation section 3 as seen in FIG. 1D.
In the present thin image display apparatus, a hollow support member 6 for suspending the thin image display apparatus body 1 on a ceiling 5 or a wall is attached at a lower or second end thereof to the driving display circuit accommodation section 3 of the rear face of the thin image display apparatus body 1 through a rocking mechanism 7.
The hollow support member 6 is formed as a rigid member so that it receives tensile stress arising from the weight of the thin image display apparatus body 1 to hold the thin image display apparatus body 1 in a predetermined posture.
Further, referring to FIG. 4, in the present thin image display apparatus, a plug 9 for being mechanically secured to a ceiling rosette 8 to establish electric connection is provided at an upper or first end of the support member 6. The ceiling rosette 8 is a ceiling wiring device for an illumination apparatus which is secured to the ceiling 5 or the like of a house and suspends an illumination apparatus thereon for establishing electric connection.
Referring to FIG. 2, the plug 9 is formed by integral molding of a synthetic resin material at the first end of the support member 6 and including a pair of electrodes 10a and 10b each formed from an L-shaped metal member and disposed in a spaced relationship by a predetermined distance from each other. The electrodes 10a and 10b are connected to power lines 11a and 11b disposed in the inside of the hollow support member 6.
The plug 9 includes a plug body 9a configured so as to hold the electrodes 10a and 10b and the support member 6 so that the total load of the thin image display apparatus body 1, support member 6 and power lines 11a and 11b can be supported by the electrodes 10a and 10b when the electrodes 10a and 10b are mechanically secured to the ceiling rosette 8.
As seen in FIG. 3 which shows a sectional view of the support member 6 taken along line III-III of FIG. 1A, the two power lines 11a and 11b are disposed in the hollow of the hollow support member 6. The power lines 11a and 11b are led to the driving display circuit accommodation section 3 of the thin image display apparatus body 1 and supply power to a driving display circuit and so forth hereinafter described therethrough.
In this instance, the plug 9 is mechanically secured to the ceiling rosette 8 by means of the electrodes 10a and 10b each in the form of an L-shaped metal member and is electrically connected to power supply terminals of the ceiling rosette 8.
Referring to FIGS. 5A to 5C, the rocking mechanism 7 includes a support shaft 6a provided at the second end. of the support member 6 and extending leftwardly and rightwardly, and a bearing 7a provided integrally with the driving display circuit accommodation section 3 on the rear face of the thin image display apparatus body 1 so as to support the support shaft 6a. 
The rocking mechanism 7 can fix the thin image display apparatus body 1 at an arbitrary angular position. Consequently, the thin image display apparatus body 1 can change its angle or posture within a range from a vertical angular position at which the thin image display apparatus body 1 lies in parallel to the support member 6 to a horizontal angular position at which the thin image display apparatus body 1 lies in a horizontal direction as seen in FIGS. 5A, 5B and 5C. In short, the thin image display apparatus body 1 can be held in a posture of a predetermined angle in accordance with a viewing condition.
In this instance, if the length of the support member 6 is set greater than the length from the rocking mechanism 7 to the upper end of the thin image display apparatus body 1, then the degree of freedom in installation of the ceiling rosette 8 to which the plug 9 is to be attached can be increased.
Further, if the rocking mechanism 7 is provided at a position between the vertical center and the upper end of the rear face of the driving display circuit accommodation section 3 of the thin image display apparatus body 1 and substantially at the center in the leftward and rightward direction, then the fulcrum is positioned closely to the center of gravity of the thin image display apparatus body 1. Therefore, even if the angle of the thin image display apparatus body 1 is set as seen in FIG. 5A, 5B or 5C, no bending stress is applied to the support member 6 but tensile stress is applied. Therefore, no deforming force is applied to any of the plug 9 and the ceiling rosette 8 to which the plug 9 is attached, and consequently, the strength of them can be maintained.
Further, in the present thin image display apparatus, an image signal is transmitted to the thin image display apparatus body 1 by power line communication (PLC) using a power line 29 as seen in FIGS. 6 and 7.
Referring to FIGS. 6 and 7, a receiver apparatus 20 is provided separately from the thin image display apparatus body 1. Further, a driving display circuit 21 is provided in the thin image display apparatus body 1 as seen in FIG. 7.

Referring now to FIG. 7, the receiver apparatus 20 includes a tuner 25 which demodulates a reception signal received by the receiver antenna 22 and supplies the demodulated image signal to a predetermined modulator 26. Meanwhile, the image signal from the external signal input terminal 20b is supplied to the modulator 26.
The image signal modulated by the modulator 26 is supplied to a superimposing circuit 27. The superimposing circuit 27 superimposes the image signal on the power line 29 through the power supply input terminal 20c using a technique which utilizes a power line as a communication line, that is, the technique of power line communication. In the thin image display apparatus, the image signal modulated by the modulator 26 successively passes the superimposing circuit 27, power supply input terminal 20c and power supply cable 23 and is superimposed on a power line 29 in a home from the home plug socket 24. The image signal further passes the ceiling rosette 8 for an illumination apparatus, the plug 9, the electrodes 10a and 10b and the power lines 11a and 11b and is transmitted to a demodulator 30 through the driving display circuit 21 of the thin image display apparatus body 1. In this instance, commercial power supply from the power supply input terminal 20c is supplied through the superimposing circuit 27 to a power supply circuit 28 of the receiver apparatus 20. Meanwhile, commercial power obtained by a separation circuit 44 is supplied to a power supply circuit 45 of the thin image display apparatus body 1.
For the protocol to be used in this instance, for example, the TCP/IP which is used in the Internet is used where digital transmission is applied.
The driving display circuit 21 in the thin image display apparatus is shown in FIG. 7. Referring to FIG. 7, a modulated image signal supplied to the driving display circuit 21 is demodulated by the demodulator 30 and is then introduced to an internal bus 32 through an Ethernet (registered trademark) I/F (interface) 31.

The graphic production synthesis circuit 35 superposes the graphic screen on the image signal and supplies a resulting signal or supplies the graphic screen in place of the image signal to a panel driving circuit 37. The panel driving circuit 37 converts the image signal into a signal necessary for the image display section 1a of the thin image display apparatus body 1 and supplies the signal to the image display section 1a so that an image is displayed on the image display section 1a. 
Meanwhile, a sound signal from the MPEG decoder 33 is supplied to a sound signal processing circuit 38 while a sound signal from the internal bus 32 is supplied to the sound signal processing circuit 38 through a sound decoder 39. The sound signal is subject to various signal processes by the sound signal processing circuit 38 and is then supplied to a speaker 41 through a sound amplification circuit 40 so that sound is generated from the speaker 41.
The CPU 36 takes charge of control of the thin image display apparatus. Software necessary for the control by the CPU 36 is stored in advance in a ROM 42, and a RAM 43 is provided for allowing the CPU 36 to execute the software. The CPU 36, ROM 42 and RAM 43 are connected to each other by the internal bus 32.
