Title:
DISPLAY DEVICE AND SOUND ON DISPLAY
Document Type and Number:
WIPO Patent Application WO/2021/213095
Kind Code:
A1
Abstract:
The embodiments of the present application provide a display device and a sound on display. A sound-making substrate is divided into a plurality of areas by means of isolation strips; at least part of the areas are attached to an electromagnetic exciter; and bending waves generated by the electromagnetic exciter are only propagated in the sound-making substrate within the areas attached to the electromagnetic exciter. Thus, when the bending waves generated by the electromagnetic exciter are propagated in different areas of the sound-making substrate of the display device, the generated bending waves are only propagated within the areas without affecting other areas. The display device and the sound on display provided in the present application can improve, when the display device produces sound under the action of electromagnetic exciters corresponding to different areas, the discrimination of the display device for sound channels, thereby improving user experience.
