Description

Mother panel and display panel manufacturing method

The present invention relates to a mother panel and a method of manufacturing the display panel, and more particularly to a mother panel capable of controlling the range of the glue application and preventing the entry of the thinned chemical liquid, and displaying the display through the mother panel The method of the panel.

Display devices have become an important human-machine interface. The current electronics market emphasizes the trend of light, thin, short and small. This is especially true for products such as mobile phones, digital cameras, camcorders, and personal digital assistants. Therefore, how to reduce the thickness of the glass substrate of the display device becomes an important issue.

When a display panel used in a display device is produced, a plurality of display panels are generally obtained by dividing one mother panel. 1A is a schematic perspective view of a conventional mother panel. FIG. 1B is a top plan view of the mother panel of FIG. 1A. Referring to FIG. 1A and FIG. 1B simultaneously, the mother panel 100 is composed of a first mother substrate 110, a second mother substrate 120, a plurality of dummy seals 130, a joint frame glue 140, and a plurality of seal frame glues 150. This is shown in Figure 1B. The mother panel 100 has a plurality of display panel regions 102 and a peripheral region 104 surrounding the display panel regions 102, wherein a plurality of display panel regions 102 are surrounded by a seal sealant 150.

The plurality of pseudo-frame glues 130 disposed in the peripheral region 104 of the mother panel 100 are arranged in a line shape and supported between the first mother substrate 110 and the second mother substrate 120. The joint frame glue 140 is coated on the peripheral region 104 to join the first A mother substrate 110 and a second mother substrate 120. Moreover, the alignment mark 160 may be disposed on the first mother substrate 110 or the second mother substrate 120 to accurately bond the first mother substrate 110 and the second mother substrate 120 to form the mother panel 100.

The bonding frame glue 140 located outside the sealing frame glue 150 serves as a space for sealing the first mother substrate 110 and the second mother substrate 120 after the bonding, so as to avoid etching the chemical liquid in the subsequent thinning process of the glass substrate. Infiltration. The purpose of using the quasi-frame glue 130 is to control the penetration range of the joint sealant 140.

However, in the case of a small-sized display panel, when the bonding of the sealant 140 is applied, since the joint sealant 140 easily flows into the interior of the mother panel 100 via the quasi-frame seal 130, a problem that the gel-penetration is too deep is formed. Fig. 1C is an enlarged schematic view of a region A of Fig. 1B. Referring to FIG. 1C, since the space for allowing the bleed is small, the joint frame glue 140 easily flows to the terminal portion 106 located beside the display panel region 102, and in particular, the terminal portion 106 has electronic components and wirings (not shown), This will cause the electronic components and wiring of the terminal portion 106 to fail, thereby causing the display panel to be scrapped.

After the fabrication of the mother panel 100 is completed, the mother panel 100 is immersed in an etching chemistry to reduce the thickness of the first mother substrate 110 and the second mother substrate 120. Fig. 1D is an enlarged schematic view of a region B of Fig. 1B. Referring to FIG. 1D , since there may be a height difference between the alignment mark 160 and the quasi-frame glue 130 , a gap 170 is formed between the first mother substrate 110 and the second mother substrate 120 . When the mother panel 100 is immersed in the etching chemical liquid CS, the etching chemical liquid CS is infiltrated into the mother panel 100 via the gap 170. In this way, the etching chemical solution CS will erode the electronic components and the wires in the terminal portion 106 or erode the first from the inside of the mother panel 100. The mother substrate 110 and the second mother substrate 120, as such, will cause the mother panel 100 to be scrapped.
