In a first aspect, to facilitate understanding of the present disclosure, a display structure provided by the present disclosure is first described in detail, and the display structure herein may be applied to an electronic display device using a flexible display screen of Organic Light-Emitting diodes (OLEDs). As shown in fig. 1 and 2, fig. 1 is a schematic structural diagram of a display screen structure provided in an embodiment of the present disclosure in a bent state, and fig. 2 is a schematic structural diagram of a display screen structure provided in an embodiment of the present disclosure in an unfolded state, where the display screen structure includes a flexible display panel layer 1 and a body portion 2, the flexible display panel layer 1 is bent based on the body portion 2, and the flexible display panel layer 1 is made of a flexible material, that is, can deform under an external acting force, so as to implement changes such as bending.
Further, in order to enable the flexible display panel layer 1 to be bent based on the body portion 2, the flexible display panel layer 1 includes non-bendable regions 11 located at two ends and a bendable region 12 located at a middle portion, and bending of the flexible display panel layer 1 is mainly achieved based on the bendable region 12; the non-bendable region 11 at one end of the flexible display panel layer 1 can be directly extended, and the extended part of the non-bendable region forms a front area of a screen of the electronic display device, so that a picture can be displayed on the front; the non-bendable region 11 at the other end of the flexible display panel layer 1 is connected with the back side of the main body of the electronic display device, so that the electronic display device is integrally mounted and sealed; the bendable region 12 is arranged between the two non-bendable regions 11 and is bent to a certain degree to form a side bending region of a screen of the electronic display device, so that the purpose that the side can display pictures and the lower frame of the electronic display device is narrow is achieved.
With continued reference to fig. 1, the flexible display panel layer 1 is connected to the main body 2 through the non-bendable region 11, specifically, the first surfaces 13 of the non-bendable regions 11 at two ends of the flexible display panel layer 1 are respectively connected to the first side and the second side opposite to the main body 2, where the first surfaces 13 refer to the surfaces of the flexible display panel layer 1 facing inward, so that the flexible display panel layer 1 unfolded in fig. 2 can be connected to the main body 2 to form the bent display screen structure shown in fig. 1, and the two non-bendable regions 11 are respectively connected to the first surfaces 13 of the two non-bendable regions 11 through the first sides and the second sides opposite to the main body 2 to fix the two non-bendable regions 11 relative to the main body 2, so that the bendable region 12 between the two non-bendable regions 11 forms a fixed bending angle, thereby realize the whole of display screen structure and buckle.
In order to facilitate the connection between the non-bendable region 11 and the body 2, a back film layer 3 is disposed on a first surface 13 of the non-bendable region 11, and the non-bendable region 11 is connected to a first side and a second side of the body 2 through the back film layer 3; the back film layer 3 can play a supporting role and a bending-resistant role for the flexible display panel layer 1, and the first surface 13 of the non-bending area 11 is provided with the back film layer 3, so that the stress borne by the bending area 12 during bending can be reduced, and the flexible display panel layer 1 can be stably connected with the body part 2 during bending.
Further, the body portion 2 includes a heat dissipation layer 21 and a connection layer 22 disposed up and down, in the embodiment of the present disclosure, an outer side surface of the heat dissipation layer 21 is used as a first side of the body portion 2, and an outer side surface of the connection layer 22 is used as a second side of the body portion 2, so that the unbendable region 11 is connected to the outer side surfaces of the heat dissipation layer 21 and the connection layer 22, respectively; the area of the heat dissipation layer 21 is the same as the display area of the electronic display device where the display screen structure is located in the embodiment of the disclosure, and the outer side surface of the heat dissipation layer 21 can be connected with the unbendable region 12 through the back film layer 3. Specifically, one side surface of the heat dissipation layer 21, that is, the outer side surface of the embodiment of the present disclosure, has viscosity, the back film layer 3 is adhered to the heat dissipation layer 21 through the outer side surface, and the heat dissipation layer 21 is configured to dissipate heat for the flexible display panel layer 1, so as to prevent the flexible display panel layer 1 from being damaged due to an excessively high temperature. In view of the fact that the heat dissipation layer 21 is usually provided with an adhesive on one side surface and the specification, i.e. the thickness, of the heat dissipation layer 21 is fixed, in order to ensure that the flexible display panel layer 1 reaches a preset bending angle and forms a stable structure, the body portion 2 in the embodiment of the present disclosure is provided with the connection layer 22 configured to connect the heat dissipation layer 21 and the back film layer 3; preferably, the connecting layer 22 is a double-sided adhesive layer, so that the formed display screen structure has better stability.
Arranging a coating layer 5 on a second surface 14 of the flexible display panel layer 1, wherein the second surface 14 refers to a surface of the flexible display panel layer 10 facing outward, and the coating layer 5 is used for protecting metal wires in an electronic display device, ensuring that signals of a screen of the electronic display device can be transmitted to a main body of the electronic display device, enabling the main body of the electronic display device to process the signals, and the like; preferably, the coating layer 5 is MCL glue.
The flexible display panel layer 1 comprises unbendable regions 11 located at two ends and a bendable region 12 located at the middle part, a connection region 4 is arranged between the unbendable region 11 and the bendable region 12, and it is considered that the end part of a back film layer 3 in the display screen structure can damage the flexible display panel layer 1, especially the connection region 4, so that the bending yield of the display screen structure is low; in addition, the end part of the back film layer 3 can form stress on the connecting area 4 of the flexible display panel layer 1, so that the metal wire generates larger stress and even leads to the technical problem of metal wire fracture.
As described above, in the display screen structure according to the embodiment of the disclosure, the thickness or the hardness of the coating layer 5 on the connection area 4 is set to be different from that of the coating layer 5 on the area except for the connection area 4, which is beneficial to increasing the elastic modulus of the connection area 4 and improving the hardness of the display screen structure. In particular, a first thickness and/or a first hardness of the coating layer 5 on the connection region 4 is greater than a second thickness and/or a second hardness of the coating layer 5 on regions other than the connection region 4.
Next, three ways of disposing the coating layer 5 on the connecting region 4 will be described in detail.
A first arrangement is that the first thickness of the coating layer 5 on the joining area 4 is greater than the second thickness of the coating layer 5 on areas other than the joining area 4. Specifically, fig. 3 is a schematic structural diagram of the display screen structure provided by the embodiment of the present disclosure in an unfolded state, and a first thickness of the coating layer 5 on the connection region 4 is greater than a second thickness of the coating layer 5 on a region except the connection region 4, and fig. 4 is a schematic structural diagram of the display screen structure provided by the embodiment of the present disclosure in a folded state, and the first thickness of the coating layer 5 on the connection region 4 is greater than the second thickness of the coating layer 5 on a region except the connection region 4. Referring to fig. 3 and 4, in the process of manufacturing the display screen structure based on the setting manner, after the coating layer 5 with the second thickness is set, for example, scan-coated, on the second surface 14 of the flexible display panel layer 1, scan-coating is continued on the connection region 4 between the bendable region 12 and the non-bendable region 11, so that the thickness of the coating layer 5 on the connection region 4 reaches the first thickness, where the first thickness is greater than the second thickness, so as to achieve the purpose of increasing the elastic modulus of the connection region 4. Further, considering that an excessively large value of the first thickness may affect the volume of the display screen structure, and an excessively small value of the first thickness may not achieve the purpose of increasing the elastic modulus of the connection region 4, the ratio of the first thickness to the second thickness is set within a second preset range, and preferably, the second preset range is 110% -250%. Of course, the above manufacturing process is only one embodiment, and in actual manufacturing, the connection region 4 and the region except the connection region 4 may be respectively scan-coated, as long as the first thickness of the coating layer 5 on the connection region 4 is greater than the second thickness of the coating layer 5 on the region except the connection region 4, which is not specifically limited in the embodiment of the present disclosure.
A second way of arranging is that the first hardness of the coating layer 5 on the connection area 4 is greater than the second hardness of the coating layer 5 on areas other than the connection area 4. Specifically, fig. 5 is a schematic structural diagram of the display screen structure provided by the embodiment of the present disclosure in an unfolded state, and a first hardness of the coating layer 5 on the connection region 4 is greater than a second hardness of the coating layer 5 on a region except the connection region 4, and fig. 6 is a schematic structural diagram of the display screen structure provided by the embodiment of the present disclosure in a bent state, and the first hardness of the coating layer 5 on the connection region 4 is greater than the second hardness of the coating layer 5 on a region except the connection region 4. Referring to fig. 5 and 6, in the process of manufacturing the display screen structure based on the setting mode, after the coating layer 5 with the second hardness is set on the second surface 14 of the flexible display panel layer 1, the coating layer 5 on the connection region 4 between the bendable region 12 and the non-bendable region 11 is cured by photo-curing or medium-curing, so that the hardness of the coating layer 5 on the connection region 4 reaches the first hardness. The first hardness is greater than the second hardness, that is, the coating layer 5 on the connecting region 4 is harder than the coating layer 5 on the regions other than the connecting region 4, thereby increasing the elastic modulus of the connecting region 4.
A third way of arranging is that the first thickness and the first hardness of the coating layer 5 on the joining area 4 are both greater than the second thickness and the second hardness of the coating layer 5 on areas other than the joining area 4. Specifically, fig. 2 is a schematic structural diagram of the display screen structure provided by the embodiment of the present disclosure in an unfolded state, and a first thickness and a first hardness of the coating layer 5 on the connection region 4 are greater than a second thickness and a second hardness of the coating layer 5 on a region other than the connection region 4, and fig. 1 is a schematic structural diagram of the display screen structure provided by the embodiment of the present disclosure in a folded state, and a first thickness and a first hardness of the coating layer 5 on the connection region 4 are greater than a second thickness and a second hardness of the coating layer 5 on a region other than the connection region 4. Referring to fig. 1 and 2, in the process of manufacturing the display screen structure, the thickness and hardness of the coating layer 5 on the connection region 4 between the bendable region 12 and the non-bendable region 11 may be increased simultaneously, that is, the first thickness of the coating layer 5 on the connection region 4 is greater than the second thickness of the coating layer 5 on the region except the connection region 4, and the first hardness of the coating layer 5 on the connection region 4 is greater than the second hardness of the coating layer 5 on the region except the connection region 4, so as to increase the elastic modulus of the connection region 4. Of course, considering that the coating layer 5 on the connection region 4 increases both in thickness and in hardness, the value of the first thickness and the value of the first hardness may be adjusted in real time to bring the elastic modulus of the connection region 4 to a preset value. For the adjustment of the thickness or hardness of the coating layer 5, reference may be made to the above-mentioned two suitable ways.
Further, when the length of the connection region 4 is set, considering that the length of the connection region 4 is too long, not only is material wasted, but also bending of the flexible display panel layer 1 is limited, for example, the bendable region 12 cannot be bent or the bending angle is too large to reach a preset angle determined in design; if the length of the connection region 4 is too short, the thickness or hardness of the bending portion of the flexible display panel layer 1 cannot be adjusted, so that the flexible display panel layer 1 cannot bear stress changes caused by bending; therefore, the ratio of the length of the connecting region 4 to the length of the bendable region 12 is within a first predetermined range, and preferably, the first predetermined range is 15% to 60%. Under the condition that the ratio of the length of the connecting area 4 to the length of the bendable area 12 is within a first preset range, the coating layer 5 on the connecting area 4 is set by using any one of the three setting modes, so that the purpose of increasing the elastic modulus of the connecting area 4 can be well achieved, that is, the bending angle of the connecting area 4 is larger on the premise of reaching a preset bending angle, the stress effect of the end part of the back film layer 3 on the flexible display panel layer 1 is reduced, the flexible display panel layer 1 is prevented from being damaged by the end part of the back film layer 3, the bending yield of the display screen structure is improved, that is, the qualification rate of the display screen structure is improved, and the production efficiency of the display screen structure is improved; further, the stress action of the end of the back film layer 3 on the flexible display panel layer 1 is reduced, and the stress generated by the metal wire can be reduced, thereby preventing the metal wire from breaking.
The second aspect of the present disclosure further provides a display panel, which employs the display screen structure described in the first aspect, so as to achieve the purpose that the lower frame of the display panel is narrower, and meet the use requirements of users.
A third aspect of the present disclosure further provides a display device, which employs the display panel described in the second aspect, and the display device can reduce stress generated by a metal wire, and ensure that a touch signal received by the display panel of the display device can be transmitted to a processing unit of the display device on the basis of preventing the metal wire from being broken, so that the processing unit processes, responds, and the like the touch signal to implement interaction between the display device and the user.
Based on the same inventive concept, a fourth aspect of the present disclosure further provides a manufacturing method of the display screen structure provided in the first aspect, and fig. 7 is a flowchart of the manufacturing method of the display screen structure, which specifically includes the following steps:
s701, bending a bendable region in the middle of a flexible display panel layer, and arranging a back film layer on a first surface of a non-bendable region at two ends, so that the non-bendable region is connected with a first side and a second side opposite to a body part through the back film layer;
S702, arranging a coating layer on a second surface of the flexible display panel layer, wherein a first thickness and/or a first hardness of the coating layer on a connection area between the non-bendable area and the bendable area are larger than a second thickness and/or a second hardness of the coating layer on an area except the connection area.
