JPH04132380A - Television receiver with front face board - Google Patents

Abstract

PURPOSE:To obtain a harmony with surroundings without any inorganic screen by providing a liquid crystal shutter held by an attaching frame as a front face board. CONSTITUTION:The outer periphery of a liquid crystal shutter 3 is held by an attaching frame 6, and the liquid crystal shutter 3 held by the attaching frame 6 is attached to the front face of a television receiver 1 by using a vis 7. And also, both electrodes 4 and 5 are connected with the neighborhoods of the surrounding circuit of a power switch 2, and both the electrodes 4 and 5 are turned into a state in which the power is supplied or interrupted between both the electrodes 4 and 5 according to the on/off operation of the power source of the television receiver 1. Therefore, the liquid crystal 3 is turned to be transparent at the time of using the television receiver. Thus, the screen can be turned into a state to be satisfactorily in harmony with surrounding furniture.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a television receiver with a front panel and a liquid crystal shutter mounted by a mounting frame.

Conventional technology In recent years, television receivers with front panels have been improved by improving the strength of the cathode ray tube surface, coating them with antistatic chemicals to prevent dust from adhering to them, and reducing the reflection of external light. The use of front panels has been decreasing due to improvements such as applying a coating agent to reduce costs, as well as efforts to reduce costs.

A conventional television receiver with a front panel will be described below.

As shown in FIG. 4, the lower end of the front glass 1o of the television receiver 9 is placed on the glass holder molded product 11, and the glass fixing molded product 12 is inserted into the glass mounting hole 13 so as to sandwich the front glass 10. Install it.

Problems to be Solved by the Invention However, in the conventional configuration described above, when the television receiver is not in use, the area of the front glass 10 becomes an inorganic space, which may disrupt the harmony with the surrounding furniture. It had some problems.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to provide a television receiver with a front plate that is well aligned with surrounding furniture even when not in use.

Means for Solving the Problems In order to solve the problems, a television receiver with a front panel of the present invention includes a television receiver, a liquid crystal shutter, and a mounting frame, and a television receiver with a front panel that includes a television receiver, a liquid crystal shutter, and a mounting frame. The liquid crystal shutter has a configuration in which the electrodes of the liquid crystal shutter are turned on and off according to the on-off operation.

Operation With this configuration, the liquid crystal shutter is transparent when the television receiver is in use, and the liquid crystal shutter is in harmony with the surrounding furniture when the television receiver is not in use.

EXAMPLE A first example of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the outer periphery of the liquid crystal shutter 3 is held by a mounting frame 6, and is mounted on the front of the television receiver 1 using a pin 7.

The picture electrodes 4 and 5 are connected near the peripheral circuit of the power switch 2, and the picture electrodes 4 and 5 are energized or turned off in response to the power on/off operation of the television receiver 1. Become.

The operation of the television receiver with a front panel configured as described above will be described below.

When the power switch 2 of the television receiver 1 is turned on, electricity is applied between the picture electrodes 4 and 5 of the liquid crystal shutter 3, and the liquid crystal shutter 3 becomes transparent, making it possible to view the screen of the television receiver 1. I can do it. Conversely, when the power switch 2 of the television receiver 1 is turned off, the picture electrodes 4 and 5 of the liquid crystal shutter 3 are also disconnected, the liquid crystal shutter 3 becomes opaque, and the screen of the television receiver 1 becomes opaque. It will be in good harmony with the furniture.

As described above, according to this embodiment, by providing the liquid crystal shutter held by the mounting frame as the front panel of the television receiver, an inorganic screen can be present when the television receiver is not in use. It is possible to create a state in which the environment is in harmony with the surroundings.

A second embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 3, the difference from the first embodiment is that a remote control transmitter 8 for operating the power switch of the television receiver is provided.

When the television receiver 1 is turned on by operating the power button of the remote control transmitter 8, the liquid crystal shutter 3 becomes transparent so that the screen can be viewed. When the television receiver 1 is turned off, it becomes opaque and can be in harmony with the surroundings.

In addition, in the first embodiment, the liquid crystal shutter 3 is operated in response to the operation of the power switch 2 of the television receiver 1, but a separate operation switch for the liquid crystal shutter 3 is provided and it is operated in response to the operation of the power switch 2 of the television receiver 1. You may also do so.

Effects of the Invention As is clear from the above description of the embodiments, the present invention has a structure in which a liquid crystal shutter held in a mounting frame is provided as a front plate of a television receiver, so that it is possible to receive images on a television receiver when not in use. It is possible to realize an excellent television receiver with a front panel in which the screen of the machine does not become inorganic and harmonizes with the surrounding furniture.
