DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device having adjusting means using optical communication and a method for adjusting the electronic device.

[0002]

2. Description of the Related Art In the process of manufacturing an electronic device, when adjusting an electronic device in an adjusting process, conventionally, an adjusting device for performing the adjustment and an electronic device to be adjusted are connected by a cable.
The necessary adjustment work for the electronic device was performed. In the case of a display device such as a computer display monitor as an electronic device to be adjusted, it is necessary to perform some screen adjustments such as screen distortion and color reproducibility (white balance) in an adjustment process at a manufacturing factory.

A display monitor for a computer (hereinafter referred to as a monitor) is placed on a pallet in a manufacturing plant, and is lined up on a conveyor line, sequentially assembled, and adjusted as an adjustment process. It is generally manufactured by a method. The adjustment process includes a number of adjustment parts such as white balance adjustment and screen distortion adjustment, and an adjuster is arranged for each part.

The adjustment of the monitor in the adjustment process in the manufacturing factory is performed using a personal computer (this personal computer is hereinafter referred to as an adjustment jig computer), and is mounted inside the monitor from the adjustment jig computer. This is carried out by transmitting various control signals for adjustment to the microprocessor in question. The microprocessor of the monitor has several tens to one hundred and several tens parameters for calculation for displaying an appropriate screen. The adjuster adjusts the screen by controlling the parameters corresponding to the respective adjustment processes with the computer for the adjustment jig while viewing the monitor.

[0005] Final adjustment in the manufacturing process of electronic equipment
A conventional example of the control process will be described with reference to an example of a display device factory adjustment system shown in FIG. Communication between the display monitor 101 mounted on the belt conveyor and the computer 102 for the adjustment jig was performed by wired communication by cable connection at a position where the adjustment table was located. As described above, by connecting the cable 107 to the communication jig connection port 103 provided on the monitor 101 and connecting the other end of the cable 107 to the communication port 104 of the adjustment jig computer 102, an adjustment control signal is transmitted. And adjustments have been made. The adjustment video is transmitted from a signal generator (not shown) to the display monitor 101 by connecting a separate connector to the monitor 101.

[0006]

The conventional monitor adjustment process has the following problems. The adjustment jig computer 102 is installed one by one in each adjustment step (image distortion adjustment step, convergence adjustment step, white balance adjustment step, etc.). On the other hand, the monitor 101
Is placed on the tray and moves on the conveyor line.
Therefore, in each step, the monitor set that has moved on the line is connected to the adjustment jig computer 102 by the cable 107 connected to the adjustment jig computer 102, and after the adjustment is completed, the cable 107 is connected.
, And connecting and disconnecting the cable 107 to the next set. This desorption is
Since the jig port used for adjustment is located at the rear part of the monitor 101, it takes several seconds for each process, and the process is completed in several tens of seconds (the adjustment time takes about 30 to 1 minute). This is an obstacle to shortening the required work time (tact time). Also, unlike a television monitor, a personal computer monitor usually does not have a remote control receiving means or a receiving antenna. Or send it by
There is also an inherent problem that the means of making adjustments using the remote control function cannot be taken, and the individual adjustment of the monitor must be performed manually.
