The present invention relates to a power consumption reduction TV that selectively supplies power to each IC of the TV to reduce power consumption. More specifically, the present invention relates to a TV for reducing power consumption by inserting a transistor switch into a power supply line supplied to each IC from an input power supply, thereby supplying power only to elements in use of the respective ICs, thereby reducing overall power consumption.

In the conventional TV driving board, ICs necessary for each mode are built in response to various input modes.

Although not all the ICs are used depending on the operation mode of the TV, power is supplied to all the ICs when power is applied to the TV driving board.

That is, power is also supplied to an IC that does not perform an operation in the above process, thereby causing unnecessary power consumption.

In order to reduce energy losses, ICs that do not perform certain processes require the development of devices to cut off the power supply. Hereinafter, the problem of the conventional TV will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing the components of a conventional TV.

Referring to FIG. 1, a conventional TV includes a DVI 21 used in the DVI input mode, an analog switch 19 used in the RGB input mode, and a component input mode. It comprises a component 17, a multi-component processor 18, and an analog switch 19 to be used in the case.

In addition, the video 12, AV switch 14, video decoder 15, and digital video format converter 16 used in the VIDEO input mode and the tuner used in the RF input mode (TUNER: 13) , An AV switch 14, a video decoder 15 and a digital video format converter 16 are included.

In addition, the IC inside the TV drive board, more specifically, the analog switch 19, the digital video format converter 16, the multi-component processor 18, the video decoder 15, the AV (Audio Video) switch 14 and An input power source 10 for supplying driving power to the tuner 13 is included.

Power required for the operation of each IC inside the TV driving board is supplied through the power line 11 extending from the input power source 10.

Referring to FIG. 1, a signal flow and an operating state of an IC according to each input mode are described. First, a signal is input to the scaler 22 through the DVI 21 in the DVI input mode. However, even in this case, unnecessary power is supplied to ICs that do not require driving such as the analog switch 19, the digital video format converter 16, the multi-component processor 18, and the like.

In the case of the RGB input mode, in addition to the analog switch 19 and the scaler 22 to which the RGB 20 and the RGB 20 signals are input, the digital video format converter 16, the multi-component processor 18, and the video decoder 15 are provided. Power is supplied to the back.

This problem occurs similarly when the TV operates using only a specific IC, such as a component input mode, a video input mode, an RF input mode, and the like.                         

In other words, power is supplied to unnecessary parts, resulting in useless power loss and shortening the life of each component.

It is an object of the present invention to provide a power consumption reduction TV capable of reducing unnecessary power consumption and extending component life by supplying power only to a specific IC being used in a TV.

The power consumption reduction TV according to the spirit of the present invention is intervened in an input power supply for supplying power to each IC in the TV driving board, a power line extending from the input power to each IC in the TV driving board, and a part of the power supply line. It includes a transistor switch for controlling the power delivery.

The present invention has the effect of providing a power-saving TV that can reduce unnecessary power consumption and extend the life of the component by supplying power only to a specific IC being used in the TV.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments presented below, and the same scope of the invention will be presented by the addition, limitation, deletion, deduction, etc. of components within the scope obvious to those skilled in the art. Could be.

2 is a view briefly illustrating the components of a TV according to the spirit of the present invention.

Referring to FIG. 2, a TV according to the spirit of the present invention includes a DVI 140 used in the DVI input mode (MODE), an analog switch 122 used in the RGB input mode, and a component ( COMPONENT) is configured to include a component 120, a multi-component processor 121, and an analog switch 122 used in the input mode.

Also, a video 110, an AV switch 112, a video decoder 113, and a digital video format converter 114 used in the video input mode and a tuner used in the RF input mode (TUNER: 111). , An AV switch 112, a video decoder 113, and a digital video format converter 114.

In addition, the IC inside the TV drive board, more specifically, the analog switch 122, the digital video format converter 114, the multi-component processor 121, the video decoder 113, the AV (Audio Video) switch 112 and An input power source 100 for supplying driving power to the tuner 111 is included.

In addition, six transistor switches 103, 104, 105, 106, 107, 108 for determining whether to supply power to each IC inside the TV driving board, and a scaler 150 for controlling the transistor switches 103, 104, 105, 106, 107, 108 through the power supply control line 102.

Referring to FIG. 2, a signal flow according to each input mode and an operation state of the IC are described. First, a signal is input to the scaler 150 through the DVI 140 in the DVI input mode.

The DVI (digital video / visual interactive: 140) refers to a technology for compressing and restoring a moving image.                     

In more detail, the DVI 140 was developed around Intel as a moving picture technology that can store video images as digital data and reproduce them with a computer. The DVI 140 is a technology that defines a standard of image information stored in a CD-ROM. By using this, one hour of video (video) data can be stored on a single disc.

The most difficult thing in storing moving picture data as digital data is that each frame of moving picture requires a huge amount of storage. One frame requires 2MB of storage, and the TV shows 30 frames per second, so a huge amount of storage is required to watch video material as you would watch on TV.

However, the DVI 140 has developed a video compression, reconstruction chip and display display chip to enable higher quality than the home VTR in a personal computer. In addition to PCs, systems for Macintosh and UNIX were also developed.

The DVI terminal can support both digital and analog, and there are two types of DVI-I and DVI-D. In the case of DVI-I, it is possible to apply D-SUB 15-pin terminal directly using gender.

The DVI-I terminal is also called DVI because the DVI terminal has an analog output and a digital output at the same time. Therefore, as long as the D-SUB conversion connector, which is used in CRT, can be used in CRT, it can also be connected to PDP TV.

However, in the case of DVI-D, only digital signals can be output unconditionally. So even if you connect the D-SUB conversion connector, you cannot watch on CRT. In other words, DVI-D can be said to be digital only.

Meanwhile, in the RGB input mode, the RGB 130 signal is transmitted to the scaler 150 through the analog switch 122.

The analog switch 122 is a switch for controlling the signal transmission through the RGB signal, the component 120 and the multi-component processor 121 used in the component input mode. That is, one of the input mode and the component mode is selected and transmitted to the scaler 150.

Meanwhile, in the video input mode, the video 110 signal is transmitted to the scaler 150 through the AV switch 112, the video decoder 113, and the digital video format converter 114.

The AV switch 112 is a device that is most suitable for connecting and using various informatization devices to video equipment such as a projection TV. The AV switch 112 is equipped with a function for converting an AV signal into an RF signal, and selects one of a video input mode and an RF input mode and transmits the signal to the video decoder 113.

The video decoder 113 is a means for decoding digitally coded image data and converting the image data into an analog signal corresponding thereto. It is a relative concept of a video encoder that converts analog image data into a calculable code, that is, a digital code used in each system.

The RF input mode, which is another mode controlled by the AV switch 112, has a signal scaler 150 through a tuner 111, an AV switch 112, a video decoder 113, and a digital video format converter 114. To pass on.

The tuner 111 is mainly used in an input unit of a wireless receiving device, and is used to tune to a frequency of a fixed radio wave (or electric signal) to select and extract only the radio wave. The tuner 111 is made by combining a suitable coil and a condenser. In general, one or both of the coil and the condenser are variable, or a combination thereof can be changed so that various frequencies can be tuned.

For example, radio receivers use a barricon (variable capacitor) to enable reception over the entire broadcast frequency band. In the case of a television receiver, the antenna is inputted from the antenna input section to the intermediate frequency converting section and integrated to form a sufficient electrical shield to be used as the tuner 111.

The scaler 150 is supplied to ICs inside a TV driving board such as an analog switch 122, a digital video format converter 114, a multi-component processor 121, a video decoder 113, an AV switch, and a tuner 111. Adjust the power.

More specifically, the transistor switches 103, 104, 105, 106, 107 and 108 formed on a part of the power line 101 extending from the input power supply 100 supplying power to each IC in the TV drive board are supplied to each IC in the TV drive board. Control the power supply.

The transistor switches 103, 104, 105, 106, 107, and 108 selectively control ON / OFF of each IC according to the control signal of the scaler 150. Control signals transmitted from the scaler 150 to the transistor switches 103, 104, 105, 106, 107, and 108 are transmitted through the power control line 102.

According to each mode, the power consumption reduction TV can supply power only to the IC in use, thereby reducing unnecessary power consumption and extending the life of each component.

The present invention has the effect of providing a power-saving TV that can reduce unnecessary power consumption and extend the life of the component by supplying power only to a specific IC being used in the TV.
