Description

FIELD OF THE INVENTION The present invention relates to a method of attaching a flexible panel to a curved surface,
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flexible panel surface bonding method, and more particularly, to a flexible panel surface bonding method in which a flexible material is attached to a curved window glass by attaching a lower protective film to a lower surface of the flexible display panel, The flexible display panel is held by using a protective film and sequentially pressed from the central portion to the outer frame portion of the flexible display panel to sequentially apply the same pressure to all the surfaces of the curved window glass to uniformly cover the curved window glass The present invention relates to a method of attaching a flexible panel to a surface of a flexible panel, which does not generate bubbles during a cementing process and can be adhered even under an atmospheric pressure environment.
A flexible material that has various elastic properties such as a film and can be variously deformed is attached to a specific material and used as an integral body in many cases. Therefore, many techniques for attaching a flexible material to a specific shape material have been developed.
Particularly, in recent years, a structure in which a flexible material is cemented to a curved window glass having a shape as shown in Fig. 1 has been used, mainly in a display device including a mobile phone and a device using a touch screen parcel. In this case, there is a more difficult problem to press the curved surface of the curved window glass against a flexible material which is deformed so much that it is difficult to apply a uniform pressure to all the surfaces.
Particularly, when the flexible panel or sheet is attached to the curved window glass, there is a high possibility that bubbles are generated in the curved surface portion, and the assembling force is also deteriorated. In order to solve this problem, when a flexible panel or sheet is attached to a curved window glass in a current state, a lacquering operation is performed in a vacuum state in order to prevent the occurrence of bubbles.
However, even if the laminating operation is carried out in the vacuum, it is not possible to prevent bubbles from occurring, and the cost of the equipment is increased and the process time is prolonged.
SUMMARY OF THE INVENTION The present invention is directed to a flexible display panel, a flexible display panel, and a flexible display panel, the flexible display panel having a lower protective film attached to the lower surface of the flexible display panel, The pressure is sequentially applied to all the surfaces of the curved window glass so as to have a uniform uniformity in the uniformity of the curved window glass while the same pressure is applied to all the surfaces of the curved window glass, And a method for attaching a flexible panel surface.
According to an aspect of the present invention, there is provided a method of attaching a flexible panel to a surface of a flexible panel, comprising the steps of: (1) forming a lower protective film (2) on a lower surface of the flexible panel to expose the protective film ); 2) mounting the curved window glass 3 so that the mounting surface is exposed downward; 3) gripping the portions of the lower protective film 2 exposed to the outside of the flexible panel 1 on both sides to mount the flexible panel 1 on the lower side of the curved window glass 3 ; 4) In the lower part of the flexible panel 1, a central portion of the flexible panel 1 is convexly deformed upward, and the flexible glass panel 3 is first brought into contact with the curved window glass 3, (1) to the upper side.
In the present invention, it is preferable that the lower protective film 2 is attached to the flexible panel 1 so as to be exposed by the remaining surfaces except the surface on which the drive circuit unit 5 is mounted.
According to the flexible panel laminating method of the present invention, the flexible material capable of freely deforming, such as a flexible panel or sheet, is pressed against the curved window glass sequentially from the center to the outward direction to prevent the bubbles from being generated, It is possible to achieve a remarkable effect that the flexible material can be attached to the curved window glass while maintaining the uniformity of spacing by applying a uniform pressure to all portions of the curved window glass.
Particularly, any part of the flexible display panel during the cementation process has an advantage of being able to grasp the entire surface of the curved surface cementation process without being damaged or contaminated.
1 is a view showing the shape of a curved window glass.
2 and 3 are views showing a state where a lower protective film is attached to a flexible display panel.
FIGS. 4 to 6 are views showing respective steps of a flexible panel surface bonding method according to an embodiment of the present invention.
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in Figs. 2 and 3, the method of attaching the flexible panel curved surface according to the present embodiment starts with the step of attaching the lower protective film 2 to the lower surface of the flexible panel 1. Fig. In general, the lower protective film 2 may be a protective film used for protecting the display panel, and may have a higher tensile strength than the conventional protective film.
2, the lower protective film 2 is formed so as to be exposed to the outside of the flexible panel 1 in the remaining surface direction excluding the surface on which the driving circuit unit 5 is installed, of the flexible panel 1 Respectively.
Of course, the lower protective film 2 may not be attached as a separate process, and may be used while the lower protective film 2 attached to the product during the product wearing process is not peeled off.
Next, the step of mounting the curved window glass 3 so that the mounting surface is exposed downward is proceeded. That is, as shown in FIG. 4, the mounting surface of the window glass 3 is mounted and exposed in the direction of the flexible panel using the mounting jig 10.
Next, as shown in FIG. 4, a portion of the lower protective film 2, which is exposed to the outside of the flexible panel 1, is gripped on both sides so that the flexible panel 1 is folded The step of mounting the lower part of the glass 3 is proceeded. That is, a portion of the lower protective film 2 which is exposed to the outside is firmly gripped on both sides by using the gripping means 20 and is mounted on the lower side of the window glass 3. By gripping the lower protective film 2 instead of the flexible display panel, it is preferable that the display panel is fundamentally excluded from the possibility of being damaged or contaminated during the cementation process.
Next, as shown in FIGS. 5 and 6, the central portion of the flexible panel 1 on the lower side of the flexible panel 1 is convexly deformed upward, and is first contacted with the curved window glass 3, The step of sequentially pressing the flexible panel 1 upward is progressed so that the contact area is enlarged to the outside.
That is, the balloon pressing member 30 is used to press the center portion of the flexible display panel 1 in the direction of the window glass 3 to make contact, and sequentially expands the contact area in the outward direction. . By sequentially pressing the flexible display panel 1 using the balloon pressing member 30, not only a uniform pressure can be applied to all the curved areas of the curved surface, but also bubbles There is an advantage that the possibility of occurrence is excluded from the source.
