In this state, both ends of the first transparent film 323a extended in this way may be folded and attached to at least a portion of each of the side surfaces ③ of the first and second windows 321 and 322 . Similarly, the second transparent film 3323b may be attached to the rear surfaces (②) of the first and second windows 321 and 322, and in this case, both ends of the second transparent film 323b are the first 1 and 2 may extend from one end of each of the windows 321 and 322 . In this state, both ends of the extended second transparent film 323b may also be bent and attached to at least a portion of each side surface of the first and second windows 321 and 322 . For example, both ends of the first transparent film 323a may be bent and attached to at least a portion of each side (③) of the first and second windows 321 and 322 . Both ends of the second transparent film 323b may also be bent and attached to at least a portion of each of the side surfaces ③ of the first and second windows 321 and 322 . Accordingly, the first and second transparent films 323a and 323b may be attached to the front surface (①), the rear surface (②), and the side surface (③) of the first and second windows 321 and 322 . At this time, by attaching the ends of both ends of the first and second transparent films 323a and 323b to face each other, the first and second transparent films 323a and 323b are sealed and the first and second windows (321, 322) and the bridge space 324 can also be sealed.

According to an embodiment, the first and second transparent films 323a and 323b may be attached to the first and second windows 321 and 322 through an adhesive member. For example, the first and second transparent films 323a and 323b may be attached to the front surface (①), rear surface (②), and side surface (③) of the first and second windows 321 and 322 using an adhesive member. there is. The adhesive member may include at least one of an optical clear adhesive (OCA), a pressure sensitive adhesive (PSA), a heat-reactive adhesive, a photo-reactive adhesive, a general adhesive, and a double-sided tape.

According to an embodiment, the material of the first and second windows 321 and 322 may include at least one of glass or plastic having a certain level of hardness. For example, the first and second windows 321 and 322 may be manufactured through CNC machining or laser machining. The material of the first and second windows 321 and 322 is described as an example of glass or plastic, but is not limited thereto. For example, the first and second windows 321 and 322 may be variously applied as long as they are made of a material that can be manufactured through CNC machining or laser machining.

According to an embodiment, the thickness of the first and second windows 321 and 322 may be in the range of 0.1 mm to 0.8 mm to withstand the pressure of the pen K1. For example, the thickness of the first and second windows 321 and 322 may be in the range of 0.1 mm to 0.35 mm. Accordingly, the first and second windows 321 and 322 formed to have such a thickness can withstand the pressing pressure of the pen K1 and, in addition, the first and second windows that can be generated when the pen K1 comes into contact. (321, 322) can be prevented from being damaged.

According to various embodiments, the flexible display 320 may further include a detection member (not shown) for detecting an input by the electromagnetic induction type pen K1. According to one embodiment, the detection member may include a digitizer. For example, the detection member may include a coil member (not shown) disposed on a dielectric substrate (not shown) to detect a resonance frequency of an electromagnetic induction method applied from the pen K1. .

According to various embodiments, the driving method (not shown) of the pen K1 is an electro magnetic resonance (EMR) method, an active electrostatic (AES) method, or a capacitive touch pen (eg, c- pen) may be included. For example, electro magnetic resonance (EMR) is a method of exchanging signals with a display using electromagnetic resonance. For example, in the EMR method (not shown), since only a device capable of generating electromagnetic induction is inserted into the pen, there is no need to insert a battery into the pen, thereby facilitating the manufacture of the pen. For example, in the EMR method, since the precision is determined by the display, which is relatively easier to make than a pen, the EMR method can relatively easily manufacture products with very high precision.

In addition, the AES method (not shown) is a method of exchanging signals with the display using static electricity. For example, in the AES method, after generating static electricity in the pen, the touch panel recognizes the static electricity to sense a signal such as coordinates and pressure of the pen. For example, in the AES method, since only a touch panel is required to recognize static electricity, the thickness of the display may be reduced. Since the AES method uses static electricity differently from the EMR method (eg, electromagnetic resonance), it is not affected by external factors in a general situation. In addition, the AES method does not generate an edge error that may occur in the EMR method. Accordingly, the AES method can further increase the precision because the precision is determined by static electricity generated from the pen.

In addition, the capacitive touch pen (not shown) collects charges opposite to that of the glass plate on the surface of the finger when the touch pen, which is a dielectric, is applied to the screen of the display in the same way as a hand touch input. It can be slightly offset and weaken the electric field measured at the surface of the glass plate. At this time, the sensor may detect a position where such a change has occurred. Accordingly, the capacitive touch pen may operate based on the sensing of the sensor.

For example, the first transparent film 323a including such a high-hardness transparent film is disposed on the front surface (①) of the first and second windows 321 and 322 to withstand the pressure caused by the contact of the pen K1. The second transparent film 323b including the elastic film is a flexible film with high elasticity to facilitate folding or unfolding of the first and second windows 321 and 322. can be made with In addition, the first and second transparent films 323a and 323b may be formed of a film having excellent transmittance.

For example, the refractive index of the liquid phase G1 may be within the range of +/-0.05. The liquid G1 may include at least one of oil and gel. For example, the liquid G1 may be variously applied as long as it is a liquid material having the same refractive index as or similar to the refractive indices of the first and second windows 321 and 322 other than oil or gel. Accordingly, the liquid phase G1 having a refractive index equal to or similar to the refractive index of the first and second windows 321 and 322 is filled in the bridge space 324, thereby forming the first and second windows 321 and 322. When viewed from above, the entire screen of the first and second windows 321 and 322 can be seen without displaying the bridge space 324 , and thereby the continuity of the first and second windows 321 and 322 is clear. screen can be provided.

The liquid phase G1 having a refractive index equal to or similar to that of the first and second windows 321 and 322 may be embedded in the first pocket structure 331 .

For example, the first pocket structure 331 may include a connection pipe 331a and a pocket member 332b. One end 331a-1 of the connecting pipe 331 may be connected to the bridge space 324 by being through-coupled to the through-hole 323d formed in the second transparent film 323b, and the connecting pipe 331a The tile end 331a - 1 may be connected to the pocket member 331b to be described later.

It is contracted (M1) or expanded (M2) by means of which the liquid phase G1 may be introduced or discharged into the bridge space 324 through the connection pipe 331a. For example, the pocket member 331b may include a tubular pocket member 331b to be contracted (M1) or expanded (M2) by elasticity.

According to various embodiments, the material of the pocket member 332 is silicone, rubber, latex, polyethylene terephthalate (PET), polyethylene ( PE), Teflon (teflon), and may include at least one of thermoplastic polyurethane (TPU).

For example, the material of the pocket member 331b may be variously applied as long as it is an elastic material that can be contracted (M1) or expanded (M2).

In this state, when the first and second windows 321 and 322 are unfolded, the bridge space 324 formed between the first and second windows 321 and 322 may vary. For example, the bridge space 324 may be larger when the first and second windows 321 and 322 are unfolded than when they are folded. Accordingly, when the first and second windows 321 and 322 are folded and unfolded, the bridge space 324 changes from a small space state to a large space state, and at this time, the pressure in the bridge space 324 increases. can do. For example, the pocket member 331b may contract (M1) as the pressure of the bridge space 324 increases according to this change. At the same time as the pocket member 331b is contracted (M1), the liquid G1 contained in the pocket member 331b may be introduced into the bridge space 324 through the connection pipe 331 . For example, as shown in FIG. 7 , the liquid G1 may be filled in the entire bridge space 324 according to the contraction M1 of the pocket member 331b. The liquid G1 prevents the display of the bridge space 324 on the screens of the first and second windows 321 and 322, so that the first and second windows 321 and 322 have a clean full screen with continuity. can provide
