Abstract

PURPOSE:To easily provide support by various kinds of units by enabling a display unit to be unloaded electrically and structurally in a personal computer(PC). CONSTITUTION:A display unit part 1 is made into a module and is set so as to be easily unloaded from a PC main body 2 in the personal computer. In such a case, interface between the display unit part 1 and the PC main body 2 is decided in advance, and the interface with the display unit part 1 is unified electrically and structurally as a display module, and the display unit can be easily replaced by another display unit in conformity to such interface specification. The design of the PC main body 2 can be replaced by every kind of display unit by fitting only the interface of the display unit part in unified standard by employing such design system, which dispenses with the re-design of the PC main body at every display unit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal computer (hereinafter referred to as a PC) having a display unit section.

[0002]

2. Description of the Related Art A PC having a conventional display unit is
The display unit could not be easily removed, and it was not possible to easily replace it with a display unit that makes full use of other technologies.

In the conventional design method, in order to replace with another display unit, for example, a display unit using other technology or a display unit having another resolution, it is necessary to redesign the structure of the PC from the beginning. However, a great deal of development man-hours were required every time another display unit was adopted.

Further, in the conventional PC, since the display unit portion is not designed to be easily removable and replaceable, another display unit cannot be easily replaced. Moreover, since the display unit is not designed to be easily removed, it cannot be replaced electrically.

[0005]

However, the conventional PC
In this design method, the display unit cannot be easily removed, so in order to replace it with another display unit, P
It was necessary to review the design of the main body of C and redesign the structure and electric circuit suitable for each display unit.

It is an object of the present invention to provide a personal computer having a display unit which can be easily removed and replaced electrically and structurally.

[0007]

To achieve the above object, a personal computer having a display unit according to the present invention is a personal computer having a computer main body and a display unit, wherein the display unit is modularized. And is structurally and electrically removably coupled to the computer body.

Further, it is composed of a combination of one computer main body and two or more display unit parts, and the display unit part is a display module in which the interface to the computer main body is unified electrically and structurally.

Further, the computer main body has a function of identifying the display unit section.

[0010]

The interface between the display unit and the computer body is structurally and electrically unified, and various types of display units can be easily replaced.

[0011]

The present invention will be described below with reference to the drawings. FIG. 1 shows a P according to a design method of an embodiment of the present invention.
Represents C.

The display unit section 1 is modularized,
It can be easily removed from the PC body 2. The interface between the display unit section 1 and the PC main body 2 is determined in advance, and the display unit section 1 has a unified interface both electrically and structurally as a display module, and it is easy if the display unit complies with this interface specification. Can be replaced with. By adopting this design method, the design of the PC main body 2 can be replaced with various display units by adjusting only the interface of the display unit part to a unified standard, and the PC main body can be re-installed for each display unit. There is no need to design.

FIG. 2 shows an example of the configuration of the display unit identification method. Several bits of ID3 on the display unit side are assigned to the display unit side and set to + 5V or 0V, and the combination forms the ID.

The ID3 of the display unit 1 can be read by software on the PC body side. The PC main body side has a register 4 for reading ID3,
ID3 can be read by assigning an O address.

On the PC body side, ID3 is set by software.
By reading, the display unit is identified, and optimum control is provided for each display unit.

For example, when connecting display units having different resolutions, the maximum resolution of the display unit can be utilized and automatically controlled by identifying the ID3 of the connected display unit.

Also, in the case of a display unit having a different control method, for example, a method in which the display unit is entirely driven, or a method in which the display unit is separately driven on the upper surface and the lower surface, the control suitable for each control method is performed. It becomes possible to do.

[0018]

As described above, according to the present invention, the display unit can be easily detached electrically and structurally from the PC, so that the PC capable of easily supporting various display units can be commercialized.
