Abstract
The invention discloses a method for testing the dispensing effect of a module, which comprises the following steps: step 1: providing an FOG assembly provided with a glue stack; step 2: arranging a detection material which can be cured and molded at the position of the glue pile, wherein the detection material is in contact with the side surface, close to the FPC, of the glass of the FOG assembly and the top surface, close to the glass, of the FPC of the FOG assembly; and step 3: the test material is cured to form a test layer, the test layer is removed and the shape of the test layer is observed. The invention can realize the judgment of the dispensing effect by visually observing the shape of the detection layer obtained by curing.
Description
Technical Field
The invention relates to the technical field of display modules, in particular to a method for testing the dispensing effect of a module.
Background
In the production and manufacturing process of the LCD display module and the OLED display module, sealant (usually UV adhesive) needs to be dispensed at the connecting position of the FPC and the glass of the display FOG assembly or the touch FOG assembly in a dispensing mode so as to protect an FPC circuit or an ITO circuit and avoid invasion of corrosive liquid and the like to bind a region. In the process of dispensing the sealant, if the dispensing position deviates, the corresponding area where the glass and the FPC meet cannot be covered, the protection effect is affected, and because the glass and the sealant are colorless and transparent, the bad effect cannot be identified even if the dispensing position deviates.
Accordingly, the prior art is deficient and needs improvement.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a method for testing the dispensing effect of a module.
The technical scheme of the invention is as follows: the invention provides a method for testing the dispensing effect of a module, which comprises the following steps: step 1: providing an FOG assembly provided with a glue stack;
step 2: arranging a detection material which can be cured and molded at the position of the glue pile, wherein the detection material is in contact with the side surface, close to the FPC, of the glass of the FOG assembly and the top surface, close to the glass, of the FPC of the FOG assembly;
and step 3: the test material is cured to form a test layer, the test layer is removed and the shape of the test layer is observed.
Further, the test material has a color.
Further, the test material is an acrylic pigment.
Further, the inspection layer completely encapsulates the glue stack.
Further, in the step 3, the shape of the inspection layer is observed through a magnifying glass or a microscope.
Further, the FOG component is a display FOG component or a touch FOG component.
Further, the inspection method is used for inspecting the LCD display module or the OLED display module.
By adopting the scheme, the invention has the beneficial effects that: the shape of the inspection layer obtained by curing can be visually observed, and the judgment on the dispensing effect is realized.

Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1 to 6, the present invention provides a method for inspecting module dispensing effect, comprising the following steps: step 1: a FOG assembly is provided with a glue stack 3.
Step 2: and arranging a curable and formable inspection material at the position of the glue pile 3, wherein the inspection material is in contact with the side surface, close to the FPC 2, of the glass 1 of the FOG component and the top surface, close to the glass 1, of the FPC 2 of the FOG component.
And step 3: the test material is cured to form a test layer 4, the test layer 4 is removed and the shape of the test layer 4 is observed.
Further, the test material has a color. In this example, the test material was an acrylic pigment. The colored inspection material is selected, so that the inspection layer 4 after curing and forming is colored, and the dispensing effect can be observed and judged conveniently.
Further, the inspection layer 4 completely wraps the glue stack 3. Since the whole glue pile 3 is completely wrapped by the inspection layer 4, all positions where the glue pile 3 is wrapped can be known, and a more accurate inspection result can be obtained.
Further, in the step 3, the shape of the inspection layer 4 may be observed through a magnifying glass or a microscope.
Further, the FOG component is a display FOG component or a touch FOG component. The inspection method can be used for inspecting the LCD display module or the OLED display module.
Referring to fig. 2 to 3, the glue stack 3 disposed in fig. 2 does not cover the corresponding position, and the ITO line 5 cannot be protected, and therefore, the ITO line is not qualified, and the glue stack 3 disposed in fig. 3 can cover the corresponding position, and therefore, the ITO line is qualified. Referring to fig. 4, fig. 4 is a cross-sectional view of an embodiment in which an inspection layer 4 is correspondingly disposed on an FOG element. Referring to fig. 5 and 6, a position a1 in fig. 5 and 6 is a bonding surface between the inspection layer and the side surface of the glass, a position a2 is a bonding surface between the inspection layer and the FPC, and a position A3 is a bonding surface between the inspection layer and the glue stack, and it can be known from observation that the inspection layer is present at the intersection position between the top surface of the FPC and the side surface of the glass in fig. 5, and therefore it can be known that the intersection position is not covered by the glue stack and cannot perform a corresponding protection function, and therefore the glue stack generated by dispensing is not qualified, while the inspection layer is not present at the intersection position between the top surface of the FPC and the side surface of the glass in fig. 6, and at this time, the glue stack generated by dispensing covers the intersection position, and the glue stack can realize a corresponding protection function, and therefore the glue stack generated by dispensing is qualified. Therefore, by the inspection method, the judgment of the dispensing effect can be realized in an intuitive observation mode.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
