Detailed Description

Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

Fig. 1 is a schematic view of a display device according to an embodiment of the present disclosure, fig. 2 is a schematic view of a cross-section A-A of fig. 1, and in order to more clearly show the structure, the feedback device 30 of fig. 2 is in a state of being separated from the mounting hole. As shown in fig. 1 and 2, the display apparatus may include a display panel 10, a support structure layer 20, and a feedback device 30. The display panel 10 may be a flexible display panel and the display device may be a flexible display device. As shown in fig. 1, the display device may include a bending region 101, and the display device may be bent by the bending region 101, so as to facilitate storage of the display device. The display panel 10 has a virtual keyboard display area 11, and the virtual keyboard display area 11 is used for displaying virtual keys 111. The support structure layer 20 is located on one side of the display panel 10 facing away from the display side, and the support structure layer 20 is provided with mounting holes 21, and the mounting holes 21 correspond to the virtual keys 111. The feedback device 30 is located in the mounting hole 21, and the feedback device 30 is configured to generate feedback vibration when the virtual key 111 receives a preset touch. It should be understood that the virtual key 111 is a key pattern displayed in the virtual keyboard display area 11, and thus, the virtual key 111 receives a preset touch, and it should be understood that the area where the virtual key 111 is located receives a preset touch, for example, the area where the key pattern is located is touched by a user with a finger.

When the flexible display device with the medium and large size is applied to business offices, a virtual keyboard display area for displaying virtual keys is arranged on the display device for the convenience of a user, the user can regard the virtual keyboard display area as a keyboard, and the user can operate the flexible display device in the virtual keyboard display area by hands, similar to an operation entity keyboard. However, in the prior art, when the user operates in the virtual keyboard display area, the virtual keyboard display area has no corresponding feedback effect or the whole screen is fed back, so that the feedback effect is absent or poor, and the user experience is reduced.

According to the display device disclosed by the embodiment of the disclosure, when the virtual key 111 is touched or knocked by a user and the touch or the knock meets the preset touch, the feedback device 30 can generate feedback vibration and transmit the feedback vibration to the virtual key 111, the user can practically feel the touch feedback effect of the virtual key 111 by sensing the feedback vibration generated by the feedback device 30, the feedback effect similar to that of the physical keyboard is achieved, the effect of the virtual key is more real, and the user experience is improved.

In the related art, a feedback film layer may be disposed on a side of the display panel facing away from the display side, and an independent linear motor may be disposed. In such a structure, when a user strikes one virtual key and the linear motor generates feedback vibration, the feedback vibration is transmitted in the feedback film layer, so that the influence on other virtual keys is caused, that is, when the user triggers one virtual key, the surrounding virtual keys are also subjected to feedback with different degrees, so that the user experience is poor.

According to the display equipment disclosed by the embodiment of the disclosure, the mounting holes corresponding to the virtual keys are arranged, and the feedback devices are arranged in the mounting holes, so that one virtual key can correspond to one feedback device, feedback vibration generated by the feedback devices can be vertically transmitted to the corresponding virtual key without influencing surrounding virtual keys, a user can more truly perceive the touch feedback effect of the virtual key, the practicability of a display area of the virtual keyboard is improved, the user experience is improved, and the effect of operating the virtual key is more authentic.

For example, a user may understand that a virtual key receives a touch when touching or clicking the virtual key with a finger. The preset touch is that the touch pressure of the user to the virtual key reaches the preset pressure. It can be understood that the virtual keyboard display area is a part of the whole display area of the display panel, and when the user uses the display device, fingers may touch the virtual keys but the user does not actually operate the virtual keys, so that the feedback device is set to generate feedback vibration when the virtual keys receive preset touch, so that the actual operation of the user can be better reflected, and misoperation caused by careless touch of the user is avoided.

In one embodiment, the display panel may be a flexible display panel, such as an Organic Light-Emitting Diode (OLED) display panel. A pressure detecting means may be provided between the feedback means 30 and the display panel. The pressure detection device can be connected with the feedback device, and the pressure detection device is used for detecting the touch pressure received by the virtual key, and the feedback device generates feedback vibration under the condition that the touch pressure reaches the preset pressure (namely the touch meets the preset touch). That is, when the user touches the virtual key, the corresponding area of the display panel deforms under the touch pressure and acts on the pressure detecting device, and when the pressure detecting device detects that the touch pressure reaches the preset pressure, the feedback device generates feedback vibration and is perceived by the user.

In one embodiment, the display panel may be a touch screen display panel. The touch screen may be connected to the feedback device, the touch screen being provided with touch electrodes corresponding to the virtual keys. When a user touches the virtual key, the touch electrode at the corresponding position of the touch screen can sense the touch and generate a signal corresponding to the touch pressure. Under the condition that the touch pressure meets the preset touch, the feedback device corresponding to the virtual key generates feedback vibration and is perceived by a user.

In one embodiment, as shown in FIG. 2, feedback device 30 may include a vibration device 31 and a cushioning structure layer 32. The buffer structure layer 32 may be disposed at a side of the vibration device 31 facing the display panel 10. The vibration device 31 is configured to generate a feedback vibration in case the virtual key 111 receives a preset touch. Such feedback device 30, the vibration device 31 will not directly contact the display panel 10, so as to avoid the feedback vibration generated by the vibration device 31 from being transmitted along the display panel 10 to affect other virtual keys. The vibration device 31 may be a vibration motor or the like that generates vibration, for example. When a user touches the virtual key, the buffer structure layer 32 can play a role in buffering touch, so that user experience can be improved, pressure intensity received by the flexible display panel can be effectively reduced, stamping caused by overlarge deformation of the display panel due to touch is avoided, and the service life of the display panel is prolonged. The buffer structure layer 32 can also transmit the vibration generated by the vibration device 31 to the corresponding virtual key, so that the fingertip of the user can be accurately fed back, and the operation effect of the virtual key is more real.

In one embodiment, as shown in fig. 2, the buffer structure layer 32 may include a metal sheet 321 and a complex function layer (SCF) 322 that are stacked. The vibration device 31 may be connected to the metal sheet 321. For example, the vibration device 31 may be fixedly connected with the metal sheet 321. The metal sheet 321 may be adhesively bonded to a functional composite layer (SCF) 322. Illustratively, the metal plate 321 may be a stainless steel plate, which may not only facilitate heat dissipation of the vibration device 31, but may also better fix the vibration device 31.

In one embodiment, as shown in fig. 2, the front projection of the vibration device 31 on the display panel 10 is located within the front projection range of the buffer structure layer 32 on the display panel 10. Such an arrangement is advantageous in better fixing of the vibration device 31, more advantageous in heat dissipation, and in improving the cushioning effect and vibration transmission effect of the cushioning structure layer 32.

In one embodiment, the number of virtual keys 111 may be multiple to simulate a real computer physical keyboard. The mounting holes 21 may be arranged in a one-to-one correspondence with the virtual keys 111, i.e. each virtual key 111 corresponds to a mounting hole 21, and each mounting hole 21 is provided with a corresponding feedback device 30. Thus, the feedback device 30, the mounting hole 21, and the virtual key 111 are provided in one-to-one correspondence. Thus, when the virtual keys 111 receive the preset touch, the corresponding feedback device 30 generates feedback vibration, and the virtual keys do not affect each other, so as to better simulate the feeling of operating the real keyboard.

Fig. 3 is a schematic rear view of a display device according to an embodiment of the disclosure. As shown in fig. 1 and 3, the shape of the virtual keys 111 may be set according to needs, for example, the shape of each virtual key 111 may be set according to the shape of a key on a physical keyboard, so that the effect of the display area of the virtual keyboard is better and more realistic. In one embodiment, as shown in fig. 3, the mounting hole 21 may have a circular shape, and the buffer structure layer 32 may have a cylindrical shape matched with the mounting hole 21. It will be appreciated that the diameter of the buffer structure layer 32 is smaller than the aperture of the mounting hole 21 so that the buffer structure layer 32 can be placed within the mounting hole 21.

Fig. 4 is a schematic diagram of a display device after being stored in an embodiment of the disclosure. It will be appreciated that, as shown in fig. 4, the foldable display device is generally provided with a drop-shaped receiving space 50 at the rotating shaft, and the display device receives tension or compression on the inner and outer sides of the display panel 10 during the receiving or unfolding process, so that the feedback device 30 located in the mounting hole 21 may be pressed against the surrounding support structure layer 20. Specifically, the vibration device 31 and the buffer structure layer 32 may be pressed with surrounding structures during storage or unfolding of the display apparatus. The mounting hole 21 is provided in a circular shape, and the buffer structure layer 32 is a columnar body matched with the mounting hole 21, so that the contact area of the feedback device 30 and the surrounding structure can be increased, the extrusion pressure per unit area can be reduced, and the extrusion condition of the feedback device 30 and the surrounding structure can be improved compared with other shapes such as a rectangle.

In one embodiment, as shown in FIG. 2. The feedback device 30 may further include a buffer sleeve 33, where the buffer sleeve 33 is disposed around the buffer structure layer 32. When the buffer structure layer 32 is extruded with the surrounding structure, the buffer sleeve 33 can play a role in buffering, so that the extrusion condition of the feedback device 30 and the surrounding structure is further improved.

As shown in fig. 2, the cushion cover 33 may include an annular wall 331 and a transverse wall 332. The annular wall 331 is disposed around the peripheral side wall of the buffer structure layer 32, and the transverse wall 332 protrudes outward from the edge of the annular wall 331 on the side close to the vibration device 31 (i.e., the lower edge of the annular wall 331), and illustratively, the transverse wall 332 protrudes radially outward from the edge of the annular wall 331 on the side close to the vibration device 31. With such a structure, the annular wall 331 can buffer the side wall of the buffer structure layer 32 from being pressed against the surrounding structure, and the transverse wall 332 can buffer the edge of the buffer structure layer 32, so as to prevent the metal sheet 321 from being hard pressed against the surrounding structure to be worn. Illustratively, the material of the cushion cover 33 may include foam. It is understood that the material of the buffer sleeve 33 may be other materials having a buffering function.

In one embodiment, as shown in fig. 2, the display apparatus may further include a support plate 40, the support plate 40 may be located at a side of the support structure layer 20 facing away from the display panel 10, and the plurality of feedback devices 30 may be mounted to the support plate 40. The support plate 40 can provide a support for the feedback device 30 in a vertical direction, so as to ensure structural strength of the display device, and facilitate the feedback device 30 to receive a preset touch. The feedback device 30 is mounted on the support plate 40, so that the feedback device 30 may not be connected to the display panel, and feedback vibration generated by the feedback device 30 is isolated from being transmitted along the display panel, and influence of the feedback device 30 on other devices is isolated.

In one embodiment, the feedback device 30 may be fully disposed within the mounting hole 21, that is, the thickness of the feedback device 30 may be less than or equal to the depth of the mounting hole 21. Thus, the support plate 40 may be attached to the surface of the support structure layer 20 on the side facing away from the display panel 10.

In one embodiment, as shown in FIG. 2, the thickness of the feedback device 30 may be greater than the depth of the mounting hole 21. Thus, when the feedback device 30 is positioned in the mounting hole 21, the vibration device 31 protrudes from the mounting hole 21. The display device may further include at least one auxiliary pad 41, the at least one auxiliary pad 41 being auxiliary supported between the support plate 40 and the support structure layer 20. It will be appreciated that, in the case where the thickness of the feedback device 30 is greater than the depth of the mounting hole 21, there is a gap between the support structure layer 20 and the support plate 40 at the non-virtual key position, and when the user touches the virtual key, the display panel is deformed greatly or deformed poorly due to the gap, and thus a stamping failure may occur. By providing the auxiliary pad 41, the gap between the non-virtual key position and the support plate 40 can be reduced, the structural level difference can be reduced, and poor stamping of the display panel can be prevented. It will be appreciated that the number and distribution of auxiliary pads 41 may be set as desired.

Illustratively, at least one auxiliary pad 41 may be coupled to the support plate 40, and the feedback device 30 is mounted to the support plate 40, such that the at least one auxiliary pad 41, the plurality of feedback devices 30, and the support plate 40 may be integrated. In the assembly process, after each feedback device 30 corresponds to each mounting hole 21, the supporting plate 40 is fixed, so that the assembly of the display device is convenient. For example, as in fig. 2, the support plate 40 may be further moved up until the feedback device 30 enters the mounting hole 21 and the upper end surface of the buffer structure layer 32 contacts the display panel 10.

In one embodiment, the thickness of the auxiliary pad 41 may be determined according to the difference between the thickness of the feedback device 30 and the depth of the mounting hole 21, for example, the thickness of the auxiliary pad 41 may be substantially equal to the difference between the thickness of the feedback device 30 and the depth of the mounting hole 21, so that the auxiliary pad 41 may completely supplement the gap between the support plate 40 and the support structure layer 20, ensuring the stability of the corresponding structure of the virtual keyboard display area.

In one embodiment, as shown in fig. 2, the buffer structure layer 32 may be the same structure as the support structure layer 20 in a direction in which the display side of the display panel 10 faces the support structure layer 20. That is, as shown in fig. 2, in the direction from the top down, the buffer structure layer 32 has the same structure as the support structure layer 20, the buffer structure layer 32 includes a laminated composite function layer (SCF) 322 and a metal sheet 321 in this order from the top down, the support structure layer 20 includes a laminated composite function layer (SCF) and a metal sheet in this order from the top down, and the thickness of each film layer of the buffer structure layer 32 is the same as the thickness of each film layer of the support structure layer 20. Therefore, after the buffer structure layer 32 is placed in the mounting hole 21, the buffer structure layer 32 can compensate the material removed by the mounting hole 21, so that the stability of supporting the display panel is ensured. Illustratively, the thickness of the auxiliary pad 41 may be the same as the thickness of the vibration device 31.

It is understood that the specific structure of the composite functional layer 322 may be set as desired. In one embodiment, the composite functional layer 322 may include a mesh type light shielding tape (EMBO), foam (Foam), and copper foil in this order from the display panel 10 to the metal sheet 321. The mesh type shading adhesive tape can play roles in shading and exhausting bubbles, the foam can play roles in protecting and buffering, and the copper foil can play roles in heat dissipation and electromagnetic shielding. In one embodiment, the composite functional layer 322 may also include a graphite layer, the location of which in the composite functional layer may be set as desired. The graphite layer may improve heat dissipation performance of the display device. In one embodiment, the composite functional layer 322 may further include a thermal repair layer, which may be adjacent to the metal sheet 321 to facilitate repair of the product. In order to further improve electromagnetic shielding, in one embodiment, the composite functional layer 322 may further include a wave-absorbing material layer, so that electromagnetic shielding of the device may be displayed.

According to the display equipment disclosed by the embodiment of the disclosure, the mounting holes corresponding to the virtual keys are formed in the supporting structure layer, the feedback device is arranged in the mounting holes, and the feedback device generates feedback vibration under the condition that the virtual keys receive preset touch, and the feedback vibration does not influence other virtual keys but is accurately transmitted to the fingertips of the user along the vertical direction, so that the user feels the vibration, the effect similar to the touch of the physical keyboard is achieved, the user experience is improved, and the effect similar to the physical keyboard is achieved.
