Problems solved by technology

If the speaker is placed behind the panel, when the sound waves pass through the liquid crystal layer, on the one hand, it is easy to disturb the liquid crystal molecules, and on the other hand, the sound waves will be absorbed by the glass substrate, which will affect the sound quality of the speaker.
Therefore, the display panel with speaker function provided by the prior art still has defects and there is room for improvement.

[0098] The following will match Figure 1 to Figure 8 A display device according to a first embodiment of the present invention will be described. see figure 1 , the first embodiment of the present invention provides a display device 1000 including a display panel 1 and a speaker module 2 . The speaker module 2 is disposed on the light emitting surface 10 of the display panel 1 and has a sound emitting film 21 and an image compensation film 22 . The sound-emitting film 21 and the image compensation film 22 are arranged along the normal direction N of the light-emitting surface 10 , so the light emitted from the light-emitting surface 10 as an image display passes through the sound-emitting film 21 and the image compensation film 22 and then exits outward. To be specific, in this embodiment, the image compensation film 22 is disposed between the display panel 1 and the sound emitting film 21, such as figure 1 shown; however, the present invention is not limited thereto. In ...

[0114] see Figure 11 , Figure 11 It is an exploded schematic view of the display device 2000 according to the second embodiment of the present invention. The main difference between this embodiment and the first embodiment is that the first embodiment respectively uses the first actuating element 5 and the second actuating element 6 to actuate the sound emitting film 21 and the image compensation film 22 as a whole, so as to generate anti-phase The first vibration wave and the second vibration wave; in this embodiment, the sound-generating membrane 21 is still disposed on one side of the light-emitting surface 10 of the display panel 1 , but is configured to be actuated by divisions.

[0115] For details, please refer to Figure 11 . In this embodiment, the display panel 1 includes a plurality of pixel regions P and light-shielding regions B between the pixel regions P. As shown in FIG. Figure 11 In the embodiment, the pixel area P refers to the area where each sub-pixe...

[0119] see Figure 13 , which shows a display device 3000 according to the third embodiment of the present invention. The main difference between this embodiment and the first embodiment is that the display device 3000 of this embodiment utilizes the principle of differential pressure actuation to make the acoustic film 21 and the image compensation film 22 emit vibratory sound waves in opposite phases.

[0120] In detail, in this embodiment, the acoustic film 21 and the image compensation film 22 are preferably made of electret material, and the display device 3000 has a first electrode group 91 and a second electrode group 92, wherein the first electrode group 91 Including at least one first electrode layer, the second electrode group 92 includes at least one second electrode layer. For example, Figure 13 In the embodiment, the first electrode group 91 has two first electrode layers 911, 912, which are respectively arranged on the upper surface 21s1 and the lower surface ...

Abstract

The invention discloses a display device which comprises a display panel and a loudspeaking module. Display panel with light emitting surface. Wherein the loudspeaking module is arranged on the lightemitting surface of the display panel, the loudspeaking module is provided with a sound production film and an image compensation film, the sound production film and the image compensation film are arranged along the normal direction of the light emitting surface, and a gap is formed between the sound production film and the image compensation film. According to the invention, the image quality ofthe display device is not influenced by the vibration of the sound film.

Description

technical field [0001] The invention relates to a display device, in particular to a display device with a sound-speaking function. Background technique [0002] In the prior art, the display devices with built-in sound generation function usually set the speaker on the frame of the panel or the rear side of the panel. However, the design of placing the speaker on the frame will compress the viewing area of ​​the panel. However, if the speaker is placed behind the panel, when sound waves pass through the liquid crystal layer, on the one hand, it is easy to disturb the liquid crystal molecules, and on the other hand, the sound waves will be absorbed by the glass substrate, which will affect the sound quality of the speaker. Therefore, the display panel with speaker function provided by the prior art still has defects and room for improvement. Contents of the invention [0003] Based on the above, one of the objectives of the present invention is to provide a display devic...
