Embodiment Construction
[0025] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0026] figure 1 It is a cross-sectional view illustrating the structure of the resin film 100 for a flat display panel used in this embodiment.
[0027] The resin film 100 is composed of a resin layer 110 , an adhesive 120 and a shaped film 130 . The resin layer 110 may be composed of one of PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), PO (polyolefine). The thickness of the resin layer 110 is required to be in the range of 3 to 30 μm when the glass substrate is sufficiently protected and the glass substrate with the protective film is cut directly using a glass scriber that cuts the glass substrate without the protective film. Within, preferably, within the range of 5 to 15 μm. It is difficult to cut the thickness of 30μm or more when using the existing cutting machine directly. Therefore, it is necessary to use ...

The present invention prevents the split on a glass substrate of a flat display panel in a process of performing a plurality of steps such as cutting, processing, modularizing and checking for a flat display panel along with ultra-thinning of the flat display penel, thereby improving strength of an ultrathin flat display panel. According to the invention, after performing a thinning step on the flat display panel which comprises a plurality of units, and before performing the cutting step by unit, a resin film is adhibited on the glass substrate of the flat display panel for being performed with the cutting step and the subsequent steps. Furthermore, the invention also provides a device which immediately adhibits the resin film on the glass substrate of the flat display panel and adhibits a protecting film on the flat display panel automatically after the thinning step. According to the invention, when the product is delivered out from warehouse after adhibiting the resin film for preventing split after performing the subsequent steps while the resin film is removed or unremoved, the average strength of the ultrathin flat display panel can be improved for more than 1.5 times.
Description
technical field [0001] The invention relates to a method for preventing cracks of glass substrates in the process of manufacturing LCD, PDP, OLED and other flat display panels. Background technique [0002] Usually, flat display panels such as LCD, PDP, OLED, etc. form TFT circuits or deposit organic layers on the bare glass to form pixels, and use color filter glass substrates or encapsulation glass substrates (encapsulation) to form pixels. glass) to close. The flat display panel produced by the above method needs to thin the overall thickness through a thinning process, and perform a cutting process in units of a given size, and perform circuit wiring such as FPCB bonding as necessary, and install driver ICs. A display function. In addition, it is necessary to implement many additional processes such as inspection processes. [0003] After the above-mentioned many processes, the glass substrate of the flat display panel is prone to cracks. Cracks significantly reduce ...
