Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-reflection film for a cathode-ray tube attached to the surface of a display screen of a cathode-ray tube for preventing light reflection, and the light-reflection anti-reflection film on the surface of the display screen of the cathode-ray tube. The present invention relates to a sticking device for sticking.

[0002]

2. Description of the Related Art When a computer or a word processor is used, a display device using a cathode ray tube as a display terminal has a problem that a display screen becomes difficult to see due to flickering of characters and reflection of external light. And V
Eye fatigue is the most frequent health disorder caused by DT (video display terminal) operation, and a VDT filter (video display terminal filter) is provided to make the display screen easier to view and reduce eye fatigue. That is being done.

[0003] In the VDT filters conventionally used, the following are common. There are many types of materials such as resin, glass, nylon, and metal.

[0004] The surface of the filter is made uneven so that external light is irregularly reflected.

[0005] An anti-reflection layer is formed on the surface of the filter.

[0006] A circularly polarizing plate is provided in front of the display screen to cut off reflected light.

However, providing a filter having unevenness in front of the display screen lowers the definition of the screen display itself. Further, forming the anti-reflection layer on the surface of the filter is very poor in productivity. Since these VDT filters are provided in front of the display screen, the distance between the display screen and the VDT filter is large, and since a separate member from the cathode ray tube is provided, maintenance management is not easy. is there.

In order to solve these problems, a method of attaching an anti-reflection film to the surface of a display screen of a cathode ray tube has recently been used to prevent light reflection. At present, the following method is used for attaching an anti-reflection film to the surface of a display screen of a cathode ray tube.

First, either the surface of the display screen of a cathode ray tube or the anti-reflection film is framed around the area where the liquid adhesive is applied to prevent dripping and then the thickness is controlled. While applying the adhesive. Subsequently, an anti-reflection film is attached to the display screen via the applied adhesive and dried. At this time, apply a large amount of adhesive in advance so that air bubbles do not get trapped between the display screen and the anti-reflection film, and overflow the excess adhesive with the display screen and light reflection. The adhesive film is stuck together, and then the overflowing adhesive is scraped off.

[0010]

However, the conventional antireflection film for a cathode ray tube adhered with the above-mentioned adhesive has the following problems.

First, since a step for preventing the adhesive from dripping and a step for drying the adhesive are required, the number of processing steps is increased by the number of steps, and the working efficiency is low.

Second, apply an adhesive more than necessary for sticking the anti-reflection film, so as not to stick with air bubbles between the display screen and the anti-reflection film. Later, since the excess adhesive is scraped off, the waste of the adhesive is large and the working efficiency is low.

Third, since the portion of the screen where the antireflection film does not follow the shape of the screen is adjusted by the amount of the adhesive, it is difficult to keep the thickness of the adhesive layer constant. In addition, even if it adjusts with an adhesive, the antireflection film floats about several millimeters on the periphery of the display screen without following the display screen. Therefore, the floating antireflection film is fixed by sticking it with a tape.

Finally, because of the above-mentioned sticking method, it is difficult to automate it, and the sticking of the antireflection film is performed manually. This causes low productivity and high cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an anti-reflection film with an adhesive when attaching the anti-reflection film to the surface of a display screen of a cathode ray tube. By using, it is possible to automate the sticking process of the antireflection film,

With the above arrangement, the CRT light-reflection film can be adhered to the surface of the display screen of the CRT using an adhesive having an adhesive force necessary for adhering to the surface of the CRT display screen. .

As described above, since the adhesive layer free from drip and drying is formed on the surface to which the film is adhered, the steps of preventing the adhesive from dripping and drying, which are conventionally required, are eliminated. This makes it possible to automate the process of attaching the antireflection film for CRT. Further, by forming the adhesive layer in advance with a uniform thickness, the thickness of the layer between the light reflection preventing film and the display screen of the CRT can be kept constant.

As described above, a filter layer for preventing light reflection can be formed on a display screen of a CRT with high productivity, low cost, and excellent quality.

The film holding means for holding the film in a state facing the screen, and the CRT light reflection preventing film held by the film holding means, the surface of the display screen of the CRT from the side opposite to the surface on which the adhesive layer is formed. Film pressing means for pressing while moving along the shape.

According to the above arrangement, the cathode ray tube is fixed by the fixing means with its display screen being opened. Next, a light-reflection film for a cathode-ray tube on which an adhesive layer made of an adhesive having an adhesive force necessary for adhering to the surface of a display screen of a cathode-ray tube is formed, and the surface on which the adhesive layer is formed is fixed by fixing means. The film is held by the film holding means in a state facing the display screen of the CRT. Lastly, the CRT light antireflection film held by the film holding means is pressed from the side opposite to the surface on which the adhesive layer is formed, while the film pressing means moves along the surface shape of the display screen of the CRT. As a result, it is stuck on the display screen of the CRT.

This makes it possible to automate the step of attaching the CRT light antireflection film, which has conventionally been a manual operation. Therefore, high productivity, low cost,
In addition, a filter layer for preventing light reflection can be formed on a display screen of a cathode ray tube with excellent quality.

According to a third aspect of the present invention, in order to solve the above-mentioned problem, in addition to the configuration of the second aspect, the film holding means is configured to adhere to the display screen of the CRT. A flexible mesh screen that covers the display screen of the cathode ray tube in a state where the anti-reflection film whose layer forming surface faces the display screen of the cathode ray tube is sandwiched between the screen and the film pressing. The means is a roller that is constantly urged to apply uniform pressure while contacting the entire width, and presses the antireflection film through the screen while moving along the display screen of the cathode ray tube, Further, it is characterized by having a suction means for sucking the air on the screen through the mesh of the screen.

According to the above construction, in addition to the function of the construction of the second aspect, the flexible net-like screen can be used as a light-reflection anti-reflection film having the adhesive layer facing the display screen of the cathode-ray tube. It is held between the display screen and the display screen of the cathode ray tube.

Attach the anti-reflection film to the display screen of the CRT. Further, at this time, the air on the screen is sucked through the mesh of the screen by the suction means.

Thus, since the light reflection preventing film for a cathode ray tube is constantly sucked by the suction means, the entire surface is always held in a form of sticking to the screen. The light antireflection film for a cathode ray tube held in such a state is stuck by the movement of the roller which is urged to press uniformly. Therefore, the antireflection film easily conforms to the shape of the display screen of the cathode ray tube, and it is possible to maintain a high degree of sticking accuracy.

Further, by adhering the CRT light-reflection film while sucking the air near the end of the CRT light-reflection film by suction means, the CRT display screen and the CRT can be placed between the display screen and the CRT. It can be attached without involving air bubbles. Therefore, by adhering a CRT light antireflection film on which an adhesive layer composed of an adhesive necessary for the adhesion is formed while sucking by a suction means, conventionally, between the display screen and the light antireflection film. It is possible to eliminate a large amount of adhesive waste that was required for sticking without entrapping air bubbles in the adhesive.

As described above, a filter layer for preventing light reflection can be formed on a display screen of a CRT with high productivity, low cost, and excellent quality.
