DETAILED DESCRIPTION OF THE EMBODIMENTS

Features of the disclosure and methods of accomplishing the same may be understood more readily by reference to the following detailed description of preferred embodiments and the accompanying drawings. The disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be more thorough and complete and will convey the disclosure to those skilled in the art, and the disclosure will only be defined by the appended claims. Like reference numerals denote like elements throughout the specification.

In the disclosure, it will be understood that when an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. For example, “A and/or B” may be understood to mean “A, B, or A and B.” The terms “and” and “or” may be used in the conjunctive or disjunctive sense and may be understood to be equivalent to “and/or.”

Throughout the specification, when an element is referred to as being “connected” to another element, the element may be “directly connected” to another element, or “electrically connected” to another element with one or more intervening elements interposed therebetween. Also, when an element is referred to as being “in contact” or “contacted” or the like to another element, the element may be in “electrical contact” or in “physical contact” with another element; or in “indirect contact” or in “direct contact” with another element.

Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper”, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the apparatus in the drawings is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. Furthermore, the apparatus may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and, as such, the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, the singular forms, such as “a” and “an,” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Moreover, the terms “comprises,” “comprising,” “includes,” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It is also noted that, as used herein, the terms “substantially,” “about,” and other similar terms, are used as terms of approximation and not as terms of degree, and, as such, are utilized to account for inherent deviations in measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, and/or sections, these elements, components, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, or section from another element, component, or section. Thus, a first element, component, or section discussed below could be termed a second element, component, or section without departing from the teachings of the disclosure.

Embodiments described in the disclosure are described with reference to plan views and cross-sectional views that are ideal schematic diagrams. Accordingly, shapes of the exemplary views may vary depending on manufacturing technologies and/or tolerances. Thus, embodiments are not limited to shown specific forms and also include variations in form produced according to manufacturing processes. Therefore, regions illustrated in the drawings are exemplary, and the shapes of the regions illustrated in the drawings are intended to illustrate the specific shapes of the regions of elements and not to limit the scope of the disclosure.

The use of cross-hatching and/or shading in the accompanying drawings is generally provided to clarify boundaries between adjacent elements. As such, neither the presence nor the absence of cross-hatching or shading conveys or indicates any preference or requirement for particular materials, material properties, dimensions, proportions, commonalities between illustrated elements, and/or any other characteristic, attribute, property, etc., of the elements, unless specified. Further, in the accompanying drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. When an embodiment may be implemented differently, a specific process order may be performed differently from the described order. For example, two consecutively described processes may be performed substantially at the same time or performed in an order opposite to the described order. Also, like reference numerals denote like elements.

Unless otherwise defined or implied herein, all terms (including technical and scientific terms) used have the same meaning as commonly understood by those skilled in the art to which this disclosure pertains. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and should not be interpreted in an ideal or excessively formal sense unless clearly defined in the specification.

FIGS.5A to5Hare schematic views illustrating a method of coating a resin RS using the mask device MM shown inFIG.1.

FIGS.5A and5Bare schematic perspective views of the mask device MM.FIGS.5C to5Eare schematic cross-sectional views taken along line I-I′ ofFIG.5B.FIG.5Fis a schematic perspective view of display panel DP and accommodation pattern RSL. FIG.5G is a schematic cross-sectional view taken along line II-II′ ofFIG.5F.FIG.5His a schematic cross-sectional view taken along line III-III′ ofFIG.5F.

Detailed configurations of the mesh mask WMM and the metal mask MT ofFIGS.5A to5Eare the same as described with reference toFIGS.1to4, and thus, details thereof are omitted.

Referring toFIG.5A, a display panel DP may include a display surface DS displaying an image to a user and a rear surface BS opposite to the display surface DS in the third direction DR3. The metal mask MT may be disposed on the rear surface BS of the display panel DP. When viewed in the plane, the display panel DP may overlap the second opening OP2.

The display panel DP may be provided with accommodation areas APA1, APA2, and APA3defined therein. When viewed in the plane, the accommodation areas APA1, APA2, and APA3may overlap the second blocking portions IEM2. When viewed in the plane, the accommodation areas APA1, APA2, and APA3may not overlap the accommodation opening SOP. The battery BAT, the camera module CAM, and the main processor MP described with reference toFIG.7may be disposed in the accommodation areas APA1, APA2, and APA3.

Referring toFIG.5B, the mesh mask WMM may be disposed on the metal mask MT. When viewed in the plane, the first frame SF1may overlap the second frame SF2. When viewed in the plane, the first opening OP1may overlap the second opening OP2. When viewed in the plane, each of the first blocking portions IEM1may overlap a corresponding second blocking portion IEM2among the second blocking portions IEM2. When viewed in the plane, the connection wires LW may overlap the mesh pattern SW.

Referring toFIG.5C, a lower surface of the second blocking frame SEM2may contact the rear surface BS of the display panel DP. The second blocking frame SEM2may be spaced apart from the first blocking frame SEM1in the third direction DR3. Upper surfaces of the second frame SF2may contact lower surfaces of the first frame SF1. When viewed in the plane, the first blocking portions IEM1may not overlap the accommodation opening SOP.

A squeezer SQ and a first nozzle NZ1may be disposed above the mask device MM. The squeezer SQ and the first nozzle NZ1may be disposed above the mesh mask WMM. The first nozzle NZ1may spray (or discharge) the resin RS to an upper surface of the mesh mask WMM. The first nozzle NZ1may spray the resin RS to the mesh pattern SW and the first blocking portions IEM1. The resin RS may include a heat curable resin, a light curable resin, or the like.

When the resin RS is sprayed from the first nozzle NZ1, the squeezer SQ may push the resin RS to a direction. The resin RS may pass through the mesh openings MOP by the squeezer SQ. The resin RS may be blocked by the first blocking portions IEM1. The resin RS may be blocked by the first blocking frame SEM1.

The resin RS may pass through the mesh openings MOP in an area except the first blocking portions IEM1and the first blocking frame SEM1, e.g., an area overlapping the accommodation opening SOP. The resin RS may be provided to the metal mask MT after passing through the mesh openings MOP. The resin RS may be provided to the accommodation opening SOP. The resin RS may be blocked by the second blocking portions IEM2. That is, the resin RS may be provided to the accommodation opening SOP around the second blocking portions SEM2without being provided onto the second blocking portions IEM2. The resin RS provided to the accommodation opening SOP may be provided on the rear surface BS of the display panel DP.

Since the accommodation areas APA1, APA2, and APA3overlap the second blocking portions IEM2, the resin RS may be provided to an area except the accommodation areas APA1, APA2, and APA3.

Referring toFIGS.5D and5E, the resin RS may be provided multiple times to the display panel DP. In an embodiment, the resin RS may be provided multiple times to the display panel DP using the first nozzle NZ1and the squeezer SQ to increase a thickness of the resin RS provided to the rear surface BS of the display panel DP.

Referring toFIGS.5F and5G, the resin RS provided to the rear surface BS of the display panel DP may be cured by a heat or ultraviolet ray. Then, the mask device MM may be removed from the display panel DP. When the resin RS is cured, accommodation spaces LPA may be defined on the accommodation areas APA1, APA2, and APA3. The accommodation spaces LPA may be referred to as recessed portions. A structure in which the accommodation spaces LPA are defined by the cured resin RS may be referred to as an accommodation pattern RSL.

The accommodation pattern RSL may be disposed on the rear surface BS of the display panel DP. A thickness in the third direction DR3of the accommodation pattern RSL may be within a range of about 100 micrometers to about 150 micrometers.

The accommodation spaces LPA may overlap the second blocking portions IEM2ofFIGS.5A to5E.

Referring toFIG.5H, a resin groove RSG may be defined in an upper portion of the accommodation pattern RSL. The resin groove RSG may overlap the connection wires LW shown inFIGS.5A to5E. The resin groove RSG may extend in the first direction DR1or the second direction DR2along the connection wires LW.

In an embodiment where the resin RS is coated using only the mesh mask WMM in case that the resin RS is sprayed to the rear surface BS of the display panel DP, the squeezer SQ may apply a force to the mesh pattern SW. In case that the force is applied to the mesh pattern SW, the mesh pattern SW may sag more as a distance from the first blocking frame SEM1increases. Accordingly, the mesh pattern SW may contact the rear surface BS of the display panel DP, and the resin RS may not be coated in a contact area between the mesh pattern SW and the rear surface BS of the display panel DP. As a result, a thickness of the coated resin RS may be smaller than about 100 micrometers.

In an embodiment where the resin RS is coated using only the metal mask MT in case that the resin RS is sprayed to the rear surface BS of the display panel DP, the connection wires LW may contact the squeezer SQ while the squeezer SQ pressurizes the resin RS. The connection wires LW may be damaged while contacting the squeezer SQ. Accordingly, the second blocking portions IEM2connected to the second frame SF2by the connection wires LW may be separated from the metal mask MT.

However, in an embodiment where the resin RS is coated on the rear surface BS of the display panel DP using the mask device MM according to the disclosure, even though the mesh pattern SW is pressurized by the squeezer SQ, the mesh pattern SW may not contact the display panel DP by the metal mask MT disposed under the mesh pattern SW. Since the squeezer SQ does not contact the connection wires LW arranged on the metal mask MT by the mesh mask WMM, the connection wires LW may not be damaged. Accordingly, the resin RS may be provided to the accommodation opening SOP after passing through the mesh opening MOP, and the resin RS may be coated with a large thickness.
