ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to an image signal processing device which uses a portable computer monitor as a display, and, more particularly, to an image signal processing system which processes television signals or external image signals and displays the same using a portable computer monitor such as a liquid-crystal display(LCD).
2. Related Art
The prior art in the area of liquid crystal television displays and/or receivers is represented by the following patents: U.S. Pat. No. 4,652,932 to Miyajima et al., entitled Liquid Crystal Display Television Receiver; U.S. Pat. No. 4,809,078 to Yabe et al., entitled Liquid Crystal Television Receiver; U.S. Pat. No. 4,982,275 to Brody, entitled Modular Flat-Screen Color Television Displays And Modules And Circuit Drives Therefor; and U.S. Pat. No. 5,119,204 to Hashimoto et al., entitled Liquid Crystal Television Set Having Driving Circuit On Peripheral Portion And Method Of Fabrication Of Image Display Section. However, for the reasons stated below, the invention disclosed herein has advantages over the prior art, and is thus distinguishable therefrom.
However, such dedicated or single function television displays and/or receivers have had a cost disadvantage in that and pays a relative large price for the single function of television program display.
In the meantime, computers have become increasingly commonplace. More recently, as a result of changing lifestyles and work patterns, there has been a rise in the use of portable computers That is, many people desire and require mobility when using their computers.
In addition, the development of computers has taken a “multimedia” direction in which a single computer has the potential for containing a variety of functions which enable the computer to be used for many different tasks. Through this multimedia development, computers are not limited by location or distance and can handle an assortment of office and leisure-related tasks.
In order to allow the computer to contain all these functions, development in the computer itself is, of course, very important. Equally important and crucial for the performance of some functions, however, are advancements made with regard to the monitor.
Monitors for portable computers now use TFT LCDs and other such displays that offer excellent display quality. It is, therefore, now possible to mount a television reception device inside the portable computer and watch television.
If the user desires television-viewing capabilities, a television reception device must be mounted inside the main body of the portable computer. But the addition of a TV reception device increases the weight of the portable computer. Further, programs used for the viewing of television are complicated and require that many adjustments be made. This is burdensome for the user acquainted with computers and complex for the novice.
As a result, there is a need for a device which allows the user to watch television using a monitor of a portable computer such that the weight of the portable computer is not increased, and the operation of viewing television is simple. Specifically, there is a need for a device which provides the advantages of a single-function, image signal processing device (i.e., simplicity) and which precludes the installation of television receiving circuitry in the portable computer (thereby increasing its weight) while at the same time allowing the use of a portable computer monitor with the image signal processing device, thereby achieving economy and the further advantages associated wide use of a high quality portable computer monitor.
SUMMARY OF THE INVENTION
The present invention has been developed in an effort to fill the above need.
It is an object of the present invention to provide an image signal processing system which is structured so as to enable the use of a portable computer monitor, such that the weight of a portable computer is not increased, and the viewing of television is easy. To achieve the above object, the present invention provides an image signal processing system which uses a display removed from a portable computer. The system includes a housing containing an image signal processing device for receiving, converting and outputting image signal data. The housing is provided with attachment members for physically attaching the display removed from the portable computer to the image signal processing device, and the image signal processing device is provided with means for electrically connecting the device to the display so as to transmit the image signal to the display.
The body is further provided with a battery receptor into which a battery used for portable computers can be inserted.
