Definitions
- the present invention relates to a method and apparatus for attaching panels, and more specifically, transparent protection for display panels such as liquid crystal displays and plasma displays used in TVs, computers (desktops, notebook computers), mobile phones and other PDAs.
- the present invention relates to a panel sticking method and a sticking device for sticking a panel.
- This liquid crystal display panel includes 2 transparent electrodes 203 and 204 formed by a metal oxide film as shown in FIG.
- a glass substrate 201, 202 is disposed so as to face each other with a gap of about several ⁇ m through a spacer 205 or the like, and a liquid crystal composition 206 is filled in the gap.
- 204 by applying a voltage to change the alignment state of the liquid crystal, thereby controlling the state in which the light from the backlight 207 disposed on the side opposite to the display surface side passes through the display panel 200.
- the light pattern (image pattern) appearing on the side can be changed.
- Such a display panel 200 is protected by covering its surface with a transparent protective panel 210 such as acrylic or glass.
- a lower electrode substrate 210a that can acquire position information on the screen by pressing the screen with a pen tip or a fingertip of a touch pen is attached to the display panel 200. Also includes a touch panel provided on the side.
- the protective panel 210 that covers the surface of the display panel 200 is provided with, for example, a spacer between the display panel 200 and the protective panel 210 so that the display panel 200 can be suitably protected when an external impact or the like is applied. Even when a shock is applied to the protective panel 210, the shock is buffered by the gap G and is directly displayed.
- the panel 200 is configured not to be applied to the panel 200.
- the protection panel 210 as a touch panel provided with the lower electrode substrate 210a described above a pressing force by a pen tip or a fingertip of the touch pen is applied to the protection panel 210. Therefore, the necessity for such a buffer is high.
- the formation of the gap G described above is effective in buffering an impact or the like, an air layer is formed by the air enclosed in the gap G, so that the refractive index of the protective panel 210 and the air layer
- the loss of light amount due to the difference in refractive index or the like reduces the optical characteristics on the display surface of the liquid crystal display, and in particular reduces the visibility in the outdoors (under sunlight).
- the gap G between the protective panel 210 and the display panel 200 is filled with a transparent silicone gel to form a silicone gel as a buffer layer instead of an air layer, and thus an impact is achieved.
- a transparent silicone gel to form a silicone gel as a buffer layer instead of an air layer, and thus an impact is achieved.
- the refractive index of the protective panel and the refractive index of the silicone gel arranged at the interval are brought close to each other, thereby reducing the optical characteristics and the image quality on the display surface of the liquid crystal display device.
- Prevention has also been proposed (prior art of Patent Document 1).
- a transparent resin sheet (weakly adhesive transparent resin sheet) made of a plasticizer-containing polymer is bonded as a buffer layer between the display panel 200 and the protective panel 210.
- Water especially distilled water, ion-exchanged water, ultrapure water, or a volatile liquid such as water / alcohol mixed solution, between the transparent resin sheet and the display panel, or between the transparent resin sheet and the transparent protective panel, or both. It has also been proposed to bring the viewing side of the liquid crystal panel and the transparent protective panel into close contact with each other (see Patent Document 1).
- the configuration in which silicone gel or the like is filled between the display panel and the transparent protective panel to eliminate the air layer reduces the reduction in optical characteristics and image quality caused by the difference in refractive index.
- a volatile liquid such as water is disposed between the display panel and the weak adhesive transparent resin film and / or between the transparent protective panel and the transparent resin film.
- a volatile liquid such as water is disposed between the display panel and the weak adhesive transparent resin film and / or between the transparent protective panel and the transparent resin film.
- the target to which the transparent protective panel is to be attached is a relatively large display panel such as a large screen TV
- the air bubbles can be obtained simply by adopting a configuration in which a volatile liquid such as water is disposed on the attachment surface. It is impossible to completely prevent the occurrence of this.
- a weakly adhesive sheet made of a plasticizer-containing polymer and a volatile liquid such as water introduced between a display panel or a transparent protective panel are attached at the time of sticking. Even if it is pushed out from the sticking surface by pressure or remains on the sticking surface, it is assumed that it will be removed from the joint surface by evaporation, etc. Therefore, if the volatile liquid at the peripheral edge of the panel evaporates and the adhesive sheet sticks directly to the surface of the display panel or protective panel in this part, the volatile liquid remaining inside the As a result, it is difficult to evaporate and remain on the sticking surface for a long time. When performing wear, volatile liquid introduced into the central portion may remain long on the bonding surface without evaporating.
- the display panel after sticking the transparent protective panel is put in a pressure vessel and this pressure is applied. It is conceivable that the inside of the container is evacuated to remove bubbles and water, or the transparent protective panel is attached under vacuum.
- the transparent resin sheet itself which serves as a buffer layer instead of the air layer, also has high transparency.
- an acrylic resin is required.
- the use of the viscoelastic body is also in the field of view.
- This phenomenon includes isocyanates that are uncrosslinked components such as tolylene diisocyanate (TDI) and diphenylmethane diisocyanate (MDI), which are used as crosslinkers in acrylic viscoelastic bodies, and hydroxyl groups in protective panels (included in acrylic resins).
- TDI tolylene diisocyanate
- MDI diphenylmethane diisocyanate
- the isocyanate group reacts with water to become carbamic acid, generating carbon dioxide and forming an amine.
- the bubbles are thought to be due to carbon dioxide produced during this reaction.
- the inventors of the present invention tried to use a low-molecular liquid gel mainly composed of a hydrophobic saturated fatty acid as a degassing aid for preventing the generation of bubbles.
- liquid gel (10 to 100 cps as an example) having a higher viscosity than water (viscosity 1 cps: 20 ° C.)
- a degassing aid is arranged at the center of the surface of one panel (for example, display panel 200), and the other panel (for example, transparent protective panel 210) is overlaid on the panel and pressed. Even if air is exhausted while pushing out the degassing aid in the peripheral direction, the degassing aid entrains the air as shown in FIG. 15C, and the air cannot be completely discharged. It was not possible to prevent the occurrence of. In particular, the larger the display panel to be processed, the more easily such bubbles are generated.
- the generated bubbles are difficult to move in the degassing aid with high viscosity, and operations such as squeezing out the bubbles toward the peripheral edge of the panel with a spatula as described above become difficult. .
