Embodiment 1

[0049] This embodiment provides a tactile feedback device, such as figure 1 As shown, it includes a touch panel 1 , several transparent first particles 4 and a feedback layer 2 . Along the light emitting direction of the flexible panel, the touch panel 1 is disposed above the surface of the flexible panel 3 , and the feedback layer 2 is disposed between the flexible panel 3 and the touch panel 1 . The first particles 4 are preferably transparent PC particles.

[0050] Such as figure 1 As shown, the feedback layer 2 is made of soft transparent material, such as transparent silicone. Transparent PC particles are filled in the feedback layer 2 in the second region 22 directly above the corresponding light-emitting region 32 and in the first region 21 directly above the non-luminous region 31 . That is, transparent particles are filled in the entire feedback layer 2. Since the first particles 4 are in a transparent state, even if they are filled in the feedback layer 2 and are ...

Embodiment 2

[0059] This embodiment provides a tactile feedback device, such as figure 2 As shown, compared with the tactile feedback device provided in Embodiment 1, the only difference is that the first particles 4 are only filled in the second region 22 facing the light-emitting region 32 of the flexible panel, and the first particles 4 must be Transparent particles, such as transparent PC particles.

[0060] In the tactile feedback device in this embodiment, by only filling the second area directly above the light-emitting area 32 with transparent PC particles, when the user touches and presses the touch panel 1, it can also obtain an instant feedback of concave-convex feeling, and then obtain A physical acknowledgment that a user input command was received.

[0061] As a first alternative embodiment, the tactile feedback device further includes second particles 5 filled in the non-light-emitting area 31 of the flexible panel 3 , and the second particles 5 evenly fill the non-light-e...

Embodiment 3

[0064] This embodiment provides a tactile feedback device, such as image 3 As shown, compared with the tactile feedback device provided in Example 1, the only difference is that the tactile feedback device also includes the second particles 5 filled in the non-light-emitting area 31 of the flexible panel 3. In this embodiment, the second The particles 5 can be transparent or opaque.

[0065] The tactile feedback device with this structure, by filling the first particles 4 in the feedback layer 2 and filling the second particles 5 in the non-luminous area 31 at the same time, increases the number of particles and the volume occupied by them in the tactile feedback device, so that When the user touches and presses the touch panel 1 , the tactile feedback device can provide tactile feedback with a more obvious concave-convex feeling, which improves the effect of tactile feedback and further improves user experience.

Abstract

The invention discloses a tactile feedback device and a flexible display, wherein, the tactile feedback device comprises a touch pad and first particles placed in a space between the touch pad and theflexible panel, wherein the first particles do not block the luminescence of the luminescent area in the flexible panel. Alternatively, the tactile feedback device includes a touch pad, and second particles placed in a non-luminescent region in the flexible panel. The flexible display includes the tactile feedback device described above. When the user presses the touch pad, because of the settingof the particles, the user can feel the uneven tactile feeling very directly and in time, thereby improving the user experience; on the other hand, the arrangement of the tactile feedback device doesnot affect the luminescence of the luminescent area in the flexible panel, so that the flexible display can provide high-quality tactile feedback through the tactile feedback device without affectingthe normal use of the flexible display.

Description

technical field [0001] The invention belongs to the field of display touch technology, and in particular relates to a touch feedback device and a flexible display. Background technique [0002] As a user input device, a touch screen has been widely used in electronic devices such as mobile phones, computers, and cameras. The touch screen can replace the traditional mechanical buttons to input user instructions to the electronic device. In order to improve the user experience and enable the user to obtain the physical confirmation that the input instruction has been received by the electronic device, a tactile feedback technology has been developed for the touch screen. . Haptic feedback means that when a user inputs instructions to an electronic device through a touch screen, force, vibration, or motion is applied to the user at the touch position to give feedback to the user. [0003] Among them, vibration feedback is a form of tactile feedback widely used in electronic d...
