Specific embodiment
The explanation of following embodiment is to can be used to the particular implementation of implementation to illustrate the present invention with reference to additional schema
Example.The direction term that the present invention is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outside", " side "
Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the present invention, rather than to
The limitation present invention.
The similar unit of structure is to be given the same reference numerals in the figure.
Refering to fig. 1, in one embodiment of rework method of full fitting rear panel defective products heavy industry of the invention, panel is bad
Product include the touch panel and display panel being bonded to each other by glue, and described method includes following steps:
Step S101: the touch panel of panel defective products and display panel are separated.
Wherein, display panel can be liquid crystal display panel, be also possible to OLED display panel or other display panels.
Glue can be OCA optical cement (Optically Clear Adhesive), be also possible to LOCA optical cement (Liquid
Optical Clear Adhesive)。
Step S102: by touch panel be stained with glue and display panel be stained with glue while be labelled in one respectively
It on interlayer, is not connected between touch panel and display panel, to form an assembly.
Wherein, intermediary layer is tempered glass.It is one embodiment of method of heavy industry after present invention fitting in conjunction with Fig. 2, Fig. 2
In, touch panel and display panel be bonded respectively with intermediary layer after schematic diagram.In the present embodiment, touch panel 11 is stained with
Glue 111 is labelled on one side on the first surface of intermediary layer 13, and what display panel 12 was stained with glue 121 is labelled to intermediary layer 13 on one side
The second surface opposite with first surface on, to form assembly 10.
Certainly, in other embodiments, when the area of intermediary layer is sufficiently large, touch panel 11 and display panel 12 are viscous
The one side of some glues can be labelled on the same surface of intermediary layer.In addition, intermediary layer for example can also be plastic material or
Ceramic material is formed.
Step S103: assembly is placed in temperature and is lower than in the environment of predetermined value with cold treatment.
Wherein, in present embodiment, the predetermined value is subzero 50 °, i.e., assembly is placed in temperature and is lower than subzero 50 °
In environment.Further, the temperature of the environment can be subzero 50 °~subzero 60 ° of range, for example, can be subzero 51 °,
Subzero 55 ° or subzero 58 ° etc..In addition, the predetermined value for example can also be subzero 40 or other lower temperature values °, it is described
The temperature of environment can also be subzero 45 ° or subzero 48 ° etc., not limit this, as long as the adhesion strength of glue can be made more micro-
It is weak and glue is detached from from touch panel, display panel.
Assembly is wherein placed in temperature to specifically include lower than in the environment of predetermined value with the step of cold treatment: by assembly
Temperature is placed in be lower than in subzero 50 ° of refrigerator with cold treatment.It in other embodiments, can also will be after assembly sealed package
It immerses in liquid of the temperature lower than 50 ° to carry out cold treatment, the liquid for example can be liquid nitrogen.
Step S104: taking out assembly after the predetermined time from the environment, and by touch panel and display surface
Plate is separated with intermediary layer respectively.
Wherein the predetermined time can be 0.5 hour to 2.5 hours range, or can be 1.5 hours to 3.5 small
When range.Specifically, in present embodiment, assembly is taken out from the environment after one hour.Certainly, described
Predetermined time can also be 1.5 hours, 2 hours or 2.5 hours, not limit this.
According to glue characteristic it is found that glue its adhesion strength under low-temperature condition will become very weak or even disappear.This reality
It applies in mode, assembly is placed on a period of time in the environment of lower temperature, thus may make the adhesion strength of glue more micro-
Weak or even disappearance, so that glue may make to be detached from from touch panel and display panel.Therefore, as shown in figure 3, by touch panel
11 and after display panel 12 separates with intermediary layer 13 respectively, the glue 111,121 of disengaging will be transferred on intermediary layer 13, by
This can remove the glue on touch panel and display panel completely, compared with traditional approach, the rework method of present embodiment
The damage to panel can be reduced, the yield done over again is improved, advantageously reduces cost.
Further, after separating touch panel and display panel with intermediary layer respectively the step of includes: to utilize to remove
Jelly removes remaining glue on touch panel and display panel.After the above-mentioned progress cold treatment to assembly, incited somebody to action
The even all of glue of major part on touch panel and display panel is detached from from touch panel and display panel, so that touching
It is a small amount of residue glue of residual without residue glue or only on panel and display panel.When there are a small amount of residue glue, adhesive remover can be cooperated to remove
Remaining a small amount of residue glue is removed, and since residual silkgum content is less, to touch panel and display panel when removing using adhesive remover
Influence is smaller, can substantially reduce the risk of damage of product than existing.
Further, after removing residue glue using adhesive remover, protection is sticked on the surface of touch panel and display panel
Film, to reduce the risk that touch panel and display panel are damaged in the handling process.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit
The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention
Decorations, therefore protection scope of the present invention subjects to the scope of the claims.
