FIG.1Aillustrates a schematic top structure view of an electronic device according to some embodiments of the present disclosure;FIG.1Billustrates a schematic cross-sectional structure view taken along a line1B-1B′ inFIG.1Aaccording to some embodiments of the present disclosure; andFIG.1Cillustrates a schematic cross-sectional structure view taken along a line1C-1C′ inFIG.1Aaccording to some embodiments of the present disclosure. It should be understood that, in order to clearly describe the present disclosure,FIGS.1A-1Conly show some elements of the electronic device10. In addition, according to some embodiments, additional features may be added to the electronic device described below.

In the embodiment, as shown inFIGS.1A-1C, the electronic device10includes a backlight module100, a display panel200, an adhesive layer300, and a flexible circuit board400. The display panel200is disposed on the backlight module100. The adhesive layer300is disposed between the backlight module100and the display panel200, and includes an opening300A. The flexible circuit board400is electrically connected to the display panel200and overlaps the opening300A in the adhesive layer300. In particular, in some embodiments, the flexible circuit board400overlaps the opening300A in the adhesive layer300indicates that the flexible circuit board400overlaps the opening300A in the adhesive layer300in the Y direction (the side view direction), or the flexible circuit board400overlaps the opening300A in the adhesive layer300in the Z direction (the top view direction).

In the embodiments of the present disclosure, as shown inFIGS.1A-1C, the backlight module100and the display panel200are connected to each other by the adhesive layer300. The opening300A in the adhesive layer300may provide good air convection or circulation, thereby reducing the adverse effect caused by water vapor condensing inside the interior of the electronic device10. In some embodiments, the flexible circuit board400is electrically connected to the display panel200. The flexible circuit board400is corresponding to the disposition of the adhesive layer300to overlap the opening300A in the adhesive layer300. In some embodiment, the flexible circuit board400is bent to a side of the backlight module100which is away from the display panel200and is disposed at a side of the display panel200which is adjacent to the opening300A, so that the possibility of light leaking from the interior of the electronic device10(e.g. the light from the backlight module100) through the opening300A could be reduced. Therefore, according to the embodiments of the disclosure, by overlapping the opening300A in the adhesive layer300with a flexible circuit board400, the adverse effect on the film caused by condensed water vapor, the light leakage on the device side, and/or the possibility of dust entering into the backlight module could be reduced, so that the high quality of the electronic device could be maintained and/or a good display effect could be presented.

According to some embodiments of the disclosure, the flexible circuit board400is an inherent, necessary element of the electronic device10. By overlapping the opening300A in the adhesive layer300with the flexible circuit board400, an additional light block element or a tortuous wind path may be omitted. Therefore, the possibility of water vapor condensation or the light leakage on the device side could be reduced, and/or it is beneficial to apply the electronic device to a Narrow Bezel design or a Bezel-less design.

In some embodiments, as shown inFIG.1A, segments of the adhesive layer300have, for example, straight line shapes extending in the X direction and the Y direction. In some embodiments, as shown inFIG.1A, wire widths W1of the segments of the adhesive layer300may be the same as or different from each other. In some embodiments, the segments of the adhesive layer300may extend along a direction different from X direction and Y direction, for example, the angle between the extending direction and X direction may be less than 45° (not shown) and/or the angle between the extending direction and Y direction may be less than 45° (not shown). In some embodiments, the adhesive layer segment of the adhesive layer300may have a bent portion (not shown). In some embodiments, an end or the bent portion of the adhesive layer segment of the adhesive layer300may have, for example, an arc-structure (not shown) caused by an automatic dispenser process, but not limited thereto.

In some embodiments, as shown inFIG.1A, the width S1of the opening300A in the adhesive layer300is, for example, in a range from 0.1 mm to 5 μm (0.1 mm≤S1≤5 mm). In some embodiments, the width S1along X direction of the opening300A is, for example, in a range from 1 mm to 4 mm (1 mm≤S1≤4 mm). In some embodiments, the width S1of the opening300A is, for example, in a range from 1 mm to 2 mm (1 mm≤S1≤2 mm). In particular, as shown inFIG.1A, the opening300A in the adhesive layer300may define a region between two adjacent segments of the adhesive layer300, and the width S1of the opening300A in the adhesive layer300may be defined as the minimum distance between the two adjacent segments of the adhesive layer300. According to some embodiments, the opening300A may have an irregular shape, such as a curved shape, a S-shape, a L-shape or a stepped shape, but not limited thereto. According to some embodiments, when the width S1of the opening300A in the adhesive layer300is smaller than 0.1 mm, the possibility of water vapor condensation may be increased; and when the width S1of the opening300A in the adhesive layer300is larger than 5 mm, the possibility of dust entering into the interior of the device may be increased. Therefore, according to some embodiments of the disclosure, when the width S1of the opening300A in the adhesive layer300is between 0.5 mm and 5 mm, the water vapor condensation and the dust pollution may be reduced. In some embodiments, the irregular shape of the opening300A may reduce light leakage.

In some embodiments, the widths S1of the openings300A in the adhesive layer300may be the same as or different from each other. The shape of the openings300A may be the same or different to each other, but not limited thereto.

That is, the flexible circuit board400overlaps the openings300A in the Y direction (the side view direction), or the flexible circuit board400overlaps the openings300A in the Z direction (the top view direction). For example, as shown inFIG.1A, one flexible circuit board400may overlap two openings300A in the adhesive layer300. The number of openings300A in the adhesive layer300overlapped by one flexible circuit board400could be adjusted according to needs, but not limited thereto.

For example, the number of openings300A overlapped by one flexible circuit board400may be the same as or different from the number of openings300A overlapped by another flexible circuit board400. The number of flexible circuit boards400, the number of openings300A in the adhesive layer300, the distribution of the openings300A in the adhesive layer300, and the number of openings300A overlapped by the flexible circuit board400may be adjusted according to the actual application, but they are not limited thereto. In some embodiments, as shown inFIG.1A, all the openings300A in the adhesive layer300are overlapped by the flexible circuit boards400. In some embodiments, some flexible circuit boards400may have different size. In some embodiments, as shown inFIG.1A, the openings300A in the adhesive layer300are non-uniform distributed in the adhesive layer300, but not limited thereto.

As shown inFIGS.1A-1C, in some embodiments, an end410of the flexible circuit board400overlaps the opening300A in the adhesive layer300in a normal direction of the display panel200(e.g. the Z direction).

In some embodiments, as shown inFIG.1A, the wire width W1of the adhesive layer300is, for example, in a range from 0.1 mm to 10 mm (0.1 mm≤W1≤10 mm), or in a range from 0.5 mm to 5 mm (0.5 mm≤W1≤5 mm), or in a range from 1 mm to 3 mm (1 mm≤W1≤3 mm), but not limited thereto. The wire width W1of the adhesive layer300, as used herein, indicates the maximum width of the adhesive layer300in a direction perpendicular to the extending direction of the adhesive layer300. For example, when the adhesive layer300extends in the X direction, the width of the adhesive layer300indicates the maximum width of the adhesive layer300in the Y direction. In some embodiments, the wire width of one adhesive layer segment of the adhesive layer300indicates the maximum width of the adhesive layer segment of the adhesive layer300in a direction perpendicular to the extending direction of the adhesive layer segment.

In some embodiments, the height H1of the adhesive layer300and the height H2of the opening300A in the adhesive layer300may be the same or different. When the height H2is smaller than 150 μm, the possibility of water vapor condensation may be increased, and when the height H2is larger than 500 μm, the possibility of dust entering into the interior of the device may be increased, and/or the amount of the adhesive layer300that is usable may be increased, and the cost may be increased.

In some embodiments, the adhesive layer300may include a UV cured glue layer (e.g. UV cured pressure sensitive adhesives), a moisture cured glue layer, a double sided glue tape, other suitable adhesive materials or elements, or a combination thereof, but not limited thereto.

In some embodiments, the adhesive layer300includes, for example, a UV cured glue layer and/or a moisture cured glue layer formed by a coating process. The coating process may form an adhesive layer300with a smaller wire width W1, so the area occupied by a bezel structure could be reduced, thereby achieving a narrow bezel effect or a bezel less effect. Furthermore, in some embodiments, the UV cured glue layer and/or the moisture cured glue layer may be completed by one dispensing process, so the manufacturing process of electronic device10may be simplified.

In some embodiments, the adhesive layer300includes a UV cured glue layer and/or a moisture cured glue layer formed by a coating process. The glue with different height may be formed in different areas by controlling the conditions of the coating process. Therefore, when the backlight module100and the display panel200have different surface structures, separation distances between junctions of the backlight module100and the display panel200are different in different regions, the adhesive layer300may have different heights in different regions to improve the adhesion between the backlight module100and the display panel200, so that to improve the adhesion strength and/or device reliability.

In some embodiments, the adhesive layer300may include a double sided glue tape, such as double-sided foam glue tape. The double sided glue tape with high viscosity could quickly connect the backlight module100and the display panel200, and provide advantages of fast process and/or strong adhesion.
