The display set 2 (e.g., the fourth body 14 of FIG. 1) may include a window 210 and a display panel 220.
The window 210 may include a transparent plate, an adhesive layer, a plastic film, a pattern layer, a metal layer, and/or a light-shielding layer.
The transparent plate may be arranged above the display panel 220, and protect the display panel 220. The transparent plate may be formed of plastic materials (e.g., an acrylic having impact resistance) or glass materials (e.g., a tempered glass).
The adhesive layer may be arranged between the transparent plate and the plastic film, and attach the plastic film to the transparent plate. The adhesive layer may be arranged in an edge area 2002 (e.g., a four-cornered ring area) of the window 210. The adhesive layer may not be overlapped with a view area 2001. Herein, the view area 2001 may indicate an area displaying an image of the display panel 220, and may be dubbed a ‘display area’. The adhesive layer may be transparent. Alternatively or additionally, the adhesive layer may be dyed using dye, pigment, coloring matters, fluorescent materials and/or phosphorescent materials. The adhesive layer may include a Pressure Sensitive Adhesive (PSA).
The plastic film may be attached or coupled to the edge area 2002 of the window 210 by the medium of the adhesive layer. The plastic film may be of a band shape corresponding to the edge area 2002 of the window 210. The plastic film may not be overlapped with the view area 2001. The plastic film may be transparent. The plastic film may be formed of materials having high heat stability and high mechanical strength. The plastic film may be a polyethyleneterephthalate (PET) film, a polycarbonate (PC) film, a polyethylene (PE) film, or a polypropylene (PP) film.
The pattern layer may include various patterns (e.g., a flat pattern or three-dimensional pattern) attached to or printed on a lower surface of the plastic film. The pattern layer may not be overlapped with the visible area 2001. The pattern layer may be formed through UV molding. The pattern layer formed through the UV molding may have a pattern corresponding to a pattern formed in a mold. The pattern of the mold may be formed through mechanical processing, laser processing or photolithography. The pattern layer may be shined by external light and show a texture of metal. A pattern of the pattern layer may be a hairline (e.g., be relatively thin). Since the pattern layer may be arranged under the transparent plate having a certain thickness, the pattern of the pattern layer may be viewable in three dimensions through the transparent plate.
The metal layer may be attached to a lower surface of the pattern layer. The metal layer may not be overlapped with the visible area 2001. The metal layer may be formed in a manner of depositing (e.g., physical vapor deposition (PVD) or chemical vapor deposition (CVD)) or coating metals (e.g., stannum (Sn), aluminum (Al), silicon (Si), titanium (Ti), titanium carbide (TiC), titanium nitride (TiN), titanium columbium (TiCB), or Al2O3) on the lower surface of the pattern layer. The metal layer may reflect external light and may be textured. Since the metal layer is arranged under the transparent plate has a certain thickness, a pattern of the metal layer may be shown in three dimensions through the transparent plate.
An area of the transparent plate not corresponding to the visible area 2001 may be expressed as a texture of metal materials owing to the underlying pattern layer and metal layer expressing the texture of metal.
The light-shielding layer may be formed on a lower surface of the metal layer. The light-shielding layer may not be overlapped with the visible area 2001. The light-shielding layer may shield external light shining an edge area of the transparent plate. The light-shielding layer may shield light traveling from the display panel 220 in order not to shine the edge area of the transparent plate. The light-shielding layer may include a black ingredient absorbing light without reflecting light. The light-shielding layer may be a layer printed with black color. The light-shielding layer may be an adhesive including a black ingredient. The light-shielding layer may include a black film and material(s) including an adhesive ingredient.
The display panel 220 may be arranged under the window 210. For example, the display panel 220 may be attached to a transparent adhesive layer, and be arranged under the light-shielding layer of the window 210. The display panel 220 may be an LCD or an AMOLED.
The display set 2 may further include a non-shown touch-sensing device. For example, a touch panel (e.g., a capacitive touch panel or a resistive touch panel) may be arranged between the window 210 and the display panel 220.

FIG. 13 is a perspective view of a portion of a device case and a connection member according to various embodiments of the present disclosure.
Referring to FIG. 13, the connection member 4 may connect between the first case body 51 and the second case body 52.
The first case body 51 may include one surface 51S1 facing a display set (2 of FIG. 12). The one surface 5151 of the first case body 51 may include a first recess 51S11. Also, the first case body 51 may include a first protrusion (P1) and a second protrusion (P2), which may be arranged in the first recess 51S11. The first protrusion (P1) may be fitted into the first through-hole (H1) of the connection member 4. Also, the second protrusion (P2) may be fitted into the second through-hole (H2) of the connection member 4.
The second case body 52 may include one surface 52S1 facing the display set 2. The one surface 52S1 of the second case body 52 may include a second recess 52S11. Also, the second case body 52 may include a third protrusion (P3) and a fourth protrusion (P4) which are arranged in the second recess 52S11. The third protrusion (P3) may be fitted into the third through-hole (H3) of the connection member 4. Also, the fourth protrusion (P4) may be fitted into the fourth through-hole (H4) of the connection member 4.
The protrusion (P1, P2, P3, or P4) may include a first part (not shown), and a second part (not shown) that are disposed between the first part and the recess (51S11 or 52S11). The second part of the protrusion (P1, P2, P3, or P4) may have a width enabling the protrusion (P1, P2, P3, or P4) to go in and out the through-hole (H1, H2, H3, or H4) of the connection member 4. The second part of the protrusion (P1, P2, P3, or P4) may be arranged in the through-hole (H1, H2, H3, or H4) of the connection member 4. The connection member 4 may be arranged between the one surface 51S1 or 52S1 of the first or second case body 51 or 52 and the first part of the protrusion (P1, P2, P3, or P4). The first part of the protrusion (P1, P2, P3, or P4) may have a relatively larger width than the through-hole (H1, H2, H3, or H4) of the connection member 4. The first part of the protrusion (P1, P2, P3, or P4) may prevent the connection member 4 from escaping from the first case body 51 and the second case body 52.
While the protrusions (P1, P2, P3, and P4) pass through the through-holes (H1, H2, H3, and H4) of the connection member 4, widths of the through-holes (H1, H2, H3, and H4) of the connection member 4 may be extended due to the elasticity of the connection member 4. After the protrusions (P1, P2, P3, and P4) fully pass through the through-holes (H1, H2, H3, and H4) of the connection member 4, the widths of the through-holes (H1, H2, H3, and H4) of the connection member 4 may return to the original shape due to the elasticity of the connection member 4.
Because a space 512 between the first case body 51 and the second case body 52 may be kept away from the folding part (F2 of FIG. 12) of the display set 2, if the electronic device (100 of FIG. 12) is folded, the space 512 between the first case body 51 and the second case body 52 may be separated in a contact state. Since the connection member 4 may be disposed between the first case body 51 and the second case body 52, an extension weight may be additionally applied to the folding part (F4) of the connection member 4. The through-holes (H1, H2, H3, and H4) of the connection member 4 may include passages (not shown) capable of guiding the movement of the second parts of the protrusions (P1, P2, P3, and P4) of the first and second case bodies 51 and 52. If the first case body 51 and the second case body 52 are separated from each other, the protrusions (P1, P2, P3, and P4) of the first and second case bodies 51 and 52 may move within the through-holes (H1, H2, H3, and H4) of the connection member 4. This movement may results in a decrease of the extension weight applicable to the connection member 4. The decrease of the extension weight applicable to the connection member 4 may stop a damage of the connection member 4.
When the electronic device (100 of FIG. 12) is in a non-folded state, the space 512 between the first case body 51 and the second case body 52 may be in a contact state. Also, the space 512 between the first case body 51 and the second case body 52 may be arranged in a position corresponding to the fifth through-hole (H5) of the connection member 4.
