It is to be noted that the terminology used herein is for the purpose of describing particular embodiments, and is not intended to limit the exemplary embodiments. As used herein, the singular " " " " " " There are features, steps, operations, devices, components, and/or combinations thereof.

As shown in FIGS. 1 and 2, the display device of the first embodiment includes a display panel 10 and an exciter 30. The display panel 10 includes a plurality of stacked components 20 which are in the form of a plate or a film. The actuator 30 is fixedly disposed on the rear surface of the display panel 10. Wherein, the adjacent components 20 are fixedly connected together by bonding, so that the display panel 10 forms an integral structure, and when the actuator 30 vibrates, the front surface of the display panel 10 vibrates and is emitted from the front surface of the display panel 10. sound.

By applying the technical solution of the embodiment, by bonding the stacked components 20 together and forming the display panel 10 into an integral plate-like structure, when the actuator 30 vibrates, the display panel 10 is entirely vibrated, thereby moving from the display panel 10. The front side makes a sound. The present application applies the principle of planar sound to a display device, and the display device of the present embodiment can apply sound by applying a planar acoustic principle.

As shown in FIG. 2, in the technical solution of the first embodiment, adjacent members 20 are bonded together by optical glue. Specifically, the optical glue has good light transmission properties, and thus does not affect the normal light-emitting display of the display panel 10 on the premise that the adjacent components 20 are bonded together. In the prior art, the various components in the display panel are independently placed. In this embodiment, the respective components 20 are bonded together by optical glue to form an integral plate-like structure. The exciter 30 is fixed to the rear side of the display panel 10. When the exciter 30 vibrates, the respective components 20 vibrate together, so that sound waves can be transmitted to the front surface of the display panel 10, and sound is emitted from the front surface of the display panel 10. .

As shown in FIG. 2, in the embodiment of the first embodiment, the entire surface of the member 20 is coated with an optical glue to bond the adjacent members 20 together. Specifically, the shaded portion shown in Figure 2 is the coated optical adhesive layer. As can be seen from Figure 2, the entire surface of the component 20 is coated with an optical glue to ensure the bonding effect. The individual components 20 are bonded together to better form a unitary body.

As shown in FIG. 1 and FIG. 2, in the technical solution of the first embodiment, the component 20 includes a liquid crystal panel 21, a soft light film 22 disposed on the rear side of the liquid crystal panel 21, a light guide plate 23, and a light reflecting film 24. Specifically, the display panel 10 in this embodiment is a liquid crystal display panel, and the type of the component 20 is not limited to the above-described soft light film 22, light guide plate 23, and light reflecting film 24, and other plate-like structures constituting the display panel 10 or Both of the film structures can be used as the above-described member 20. Preferably, the display panel 10 can also be an LED display panel, and accordingly, the component 20 can also include an LED panel.

Preferably, in the first embodiment, the soft light film 22 is a single layer or a plurality of layers.

Preferably, the display device in the first embodiment is a liquid crystal display. The above liquid crystal display can be applied to a television or a computer. Or use as an outdoor screen.

As shown in FIG. 3, the second embodiment of the display device according to the present application differs from the first embodiment in that the edge of the member 20 is coated with an optical glue, and the adjacent members 20 are bonded together and adjacent. The portion of the space between the components 20 that is inside the optical glue is a vacuum. Specifically, the shaded portion of Figure 3 represents the glue layer of the coated optical glue. As can be seen in Figure 3, an optical glue is applied at the periphery of the film-like or plate-like member 20. And the optical adhesive is not coated on the inner side surface of the plate member 20. After the adjacent members 20 are bonded together, the position between the adjacent members 20 where no optical glue is applied is subjected to a vacuuming operation, thereby ensuring that sound waves can be transmitted to the frontmost member 20. Specifically, the above-mentioned "the portion of the space between the adjacent members 20 located inside the optical glue" is also the portion of the space between the adjacent members 20 that is not coated with the optical glue.

It can be seen from the above that the adjacent components of the present application are bonded and fixed together by bonding: the surfaces of the adjacent two components are all glued together, or the edges of the adjacent two components are adhered. Together, the middle part is treated with a vacuum.

Further, for the purpose of transmitting the vibration of the exciter to the liquid crystal screen, the method of forming a whole liquid crystal panel by the above components is the protection scope of the patent.
