Display film attaching method and apparatus for electronic device

Abstract

A display film attaching method an apparatus thereof are provided to implement perfect high-precision film attachment by attaching a film to a display panel of an electronic device (a cell phone, a TV, an electronic dictionary and so on) through a pressing force with high efficiency. The method comprises the steps: on an upper side, a flat display panel for the electronic device is fixed / arranged on a panel on a panel fixing unit in a horizontal state; on a lower side, a film with a certian size is fixed on a curved surface of a curved extrusion plate of a complete large arc curved surface in a certain length zone; and when the curved surface, adhered with the film, of the curved extrusion plate, corresponds to the bottom of the upper panel at intervals, rolling motion is conducted successively from a fulcrum on one side of the bottom of the panel to a fulcrum on the other side. Therefore, extruded film attachment of rolling motion of the curved surface for extrusion and film attachment is realized.

Description

technical field [0001] The present invention relates to a new type of high-efficiency attaching method and its device capable of attaching films on the surface of display panels (LCD, PDA, PAP, etc.) of electronic equipment (mobile phones, TVs, electronic dictionaries, etc.) more quickly, simply and accurately . Background technique [0002] In general, display panels (LCD, PDA, PAP, etc.) for electronic devices (mobile phones, TVs, electronic dictionaries, etc.) are attached with micro-unit films (POL, FRP, etc.) for the purpose of surface protection or anti-fingerprints, etc. It will be listed later. [0003] In addition, as a method of affixing the above-mentioned film on the surface of a display panel (glass) for electronic equipment, there is a method of simply attaching a flat-shaped film with a protective cover removed to the panel. However, as the display panel speeds up recently, As it becomes lighter and thinner, if the protective skin attached to the adhered fil...

Problems solved by technology

[0003] In addition, as a method of affixing the above-mentioned film on the surface of a display panel (glass) for electronic equipment, there is a method of simply attaching a flat-shaped film with a protective cover removed to the panel. However, as the display panel speeds up recently, As it becomes lighter and thinner, if the protective skin attached to the adhered film is peeled off, serious curling (the phenomenon that both ends are bent along the width of the film, curl) will occur, resulting in air bubbles and an increase in the defective rate , in severe cases, not only can not complete the film attachment, but also increase the cost and waste of work time, resulting in reduced productivity and quality

[0004] In order to overcome the above shortcomings, although various solutions have been explored in various fields, it is necessary to perfectly attach the micro-unit thin film paper to the surface of the sensitive display panel (glass) without generating bubbles. Very difficult, so no good solution has been proposed so far

[0005] Although the method of using rollers or rollers for attachment has been widely proposed recently, when the rollers with a limited diameter are in close contact with the brittle panel for attachment, cracks or chipping often occur during the contact process. cracked, damaged, so it caused a huge obstacle to production
