Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1 and fig. 2, fig. 1 is an exploded view of a display device 10 according to a first embodiment of the present invention, and fig. 2 is an assembled view of the display device 10 in fig. 1. The display device 10 has a directional sound function, can be combined by one or more displays, and performs adjustment and control of sound channels according to the number of displays. The display apparatus 10 of the first embodiment is a single first display 12, and the first display 12 includes a first housing 14, a first display panel 16, a back plate 18, a first ultrasonic wave output module 20, and a first processor 22. The first display panel 16 and the back panel 18 may be disposed within the first housing 14. The first ultrasonic output module 20 is disposed between the first display panel 16 and the back plate 18.
Generally, the back plate 18 is usually made of metal material, and the sound wave signal cannot pass through, so the first ultrasonic output module 20 is disposed in front of the back plate 18; on the other hand, each optical component of the first display panel 16 is made of a plastic material, and the sound wave signal output by the first ultrasonic output module 20 can pass through the first display panel 16, so that the first ultrasonic output module 20 can be hidden behind the first display panel 16, and the sound wave signal can pass through the first display panel 16 to be sent to the outside of the first display 12, thereby achieving the purpose of front sound emission. In addition, the first ultrasonic output module 20 can directly abut against the first display panel 16, so that the acoustic signal can penetrate through the first display panel 16; alternatively, the first ultrasonic output module 20 may be spaced apart from the first display panel 16 to form a gap (i.e., a gap is formed between the first ultrasonic output module and the first display panel), and as long as no solid or densely-wired metal structure is disposed in the gap, the acoustic signal can pass through the gap, which meets the design requirements of the present invention.
For example, if the first display 12 is a side-in type backlight display, the first ultrasonic output module 20 may be installed below the optical components of the first display panel 16, such as the light guide plate and the reflective sheet, and above the solid metal back plate 18, in other words, the first ultrasonic output module 20 is installed between the optical components of the first display panel 16 (including the light guide plate and the reflective sheet) and the solid metal back plate 18. If the first display 12 is a direct-type backlight display, the circuit board of the direct-type backlight display has metal wiring, and the sound wave signal cannot pass through, so the circuit board can be regarded as the back plate 18, and the first ultrasonic output module 20 needs to be installed above the circuit board, in other words, the first ultrasonic output module 20 is installed between the first display panel 16 and the circuit board (i.e., the back plate 18). If the first display 12 is an oled display, the first ultrasonic output module 20 is installed below the oled panel and above the metal back plate 18, in other words, the first ultrasonic output module 20 is installed between the oled panel and the metal back plate 18.
The first processor 22 is electrically connected to the first display panel 16 and the first ultrasonic output module 20. The first processor 22 can drive the first ultrasonic output module 20 to output a corresponding acoustic signal according to the image data played by the first display panel 16. The sound wave signal generated by the first ultrasonic output module 20 has a narrow sound beam and has directionality in its propagation direction, and can directionally focus the output sound wave of the display device 10 in a specific area, such as, but not limited to, the area toward which the light-emitting surface of the first display panel 16 faces. In the first embodiment, the display apparatus 10 has only a single first display 12, and the first ultrasonic output module 20 may be disposed near any side of the first casing 14, for example, near the lower side as shown in fig. 1, but the practical application is not limited thereto.
Referring to fig. 3, fig. 3 is an exploded view of a display device 10 according to a second embodiment of the present invention. In the second embodiment, the components having the same numbers as those in the first embodiment have the same structures and functions, and the description thereof will not be repeated. The difference between the second embodiment and the first embodiment is that the display apparatus 10 (i.e. the first display 12') may further include a second ultrasonic output module 24, the second ultrasonic output module 24 is electrically connected to the first processor 22, and the second ultrasonic output module 24 and the first ultrasonic output module 20 are respectively disposed near two opposite sides of the first display panel 16. In the embodiment shown in fig. 3, the first ultrasonic wave output module 20 and the second ultrasonic wave output module 24 are respectively disposed near the left and right sides of the first display panel 16, but the practical application is not limited thereto, and for example, the first ultrasonic wave output module and the second ultrasonic wave output module may be disposed near the upper and lower sides of the first display panel 16; specifically, the upper side of the first display panel 16 is, for example, a side where a top end of the first display panel 16 is located, the lower side of the first display panel 16 is, for example, a side where a lower end of the first display panel 16 is located, and the left side and the right side of the first display panel 16 are oppositely disposed and are located between the top end and the bottom end of the first display panel 16.
In the second embodiment, the first processor 22 may drive the first ultrasonic output module 20 and the second ultrasonic output module 24 to simultaneously or separately send the acoustic signal according to a control command, for example, a command obtained by analyzing image data played by the first display panel 16. The first ultrasonic output module 20 and the second ultrasonic output module 24 can be used as the left and right sound channels of the first display 12', and respectively output the corresponding left sound channel sound wave signal and right sound channel sound wave signal; alternatively, the first ultrasonic output module 20 and the second ultrasonic output module 24 can also be used as a single channel of the first display 12', i.e. each is used to output a sound signal mixed by left and right channels.
Referring to fig. 4, fig. 4 is an external view of a display device 10' according to a third embodiment of the present invention. In the third embodiment, the components having the same numbers as those in the previous embodiments have the same structures and functions, and the description thereof will not be repeated. The third embodiment differs from the previous embodiments in that the display device 10 'may comprise two or more displays, such as the first display 12' and the second display 26 arranged side by side. The second display 26 may include a second housing 28, a second display panel 30, a third ultrasonic output module 32, a fourth ultrasonic output module 34, and a second processor 36. The second display panel 30 is disposed within the second housing 28. The third ultrasonic output module 32 and the fourth ultrasonic output module 34 can be hidden behind the second display panel 30 (the rear of the second display panel 30 is an area toward which the back of the second display panel 30 faces, and the back of the second display panel 30 and the light emitting surface of the second display panel 30 are opposite to each other), and are respectively disposed close to two opposite sides of the second display panel 30. The second processor 36 can be electrically connected to the second display panel 30, the third ultrasonic wave output module 32 and the fourth ultrasonic wave output module 34, respectively.
The sound wave signals output by the third ultrasonic output module 32 and the fourth ultrasonic output module 34 can pass through the second display panel 30 to be transmitted to the outside of the second display 26. The first display 12' and the second display 26 may be disposed side by side for playing image data of a wide frame, at this time, the first processor 22 and the second processor 36 share a control command, for example, the first processor 22 outputs the control command to drive the first display panel 16 to display a frame and drive the first ultrasonic output module 20 and the second ultrasonic output module 24 to send a sound wave signal, and the second processor 36 drives the second display panel 30 to display a frame and drive the third ultrasonic output module 32 and the fourth ultrasonic output module 34 to send a sound wave signal according to the control command from the first processor 22.
Taking the implementation example shown in fig. 4 as an example, the first display 12 ' is laterally spliced to the second display 26 in a manner that the second ultrasonic output module 24 is adjacent to the third ultrasonic output module 32, the display apparatus 10 ' can use the first display panel 16 and the second display panel 30 to respectively play the image data frames of the right half and the left half, at this time, the first ultrasonic output module 20 and the fourth ultrasonic output module 34 can be respectively used as a left sound channel speaker and a right sound channel speaker of the display apparatus 10 ', and the second ultrasonic output module 24 and the third ultrasonic output module 32 can be selectively used as a monaural speaker or switched to a mute mode.
If the three displays are laterally arranged and spliced to form the display equipment, the ultrasonic output module of the right display can be used as a right sound channel loudspeaker of the display equipment, and the ultrasonic output module of the left display can be used as a left sound channel loudspeaker of the display equipment. The ultrasonic output module of the middle display can be set to be a single sound channel loudspeaker or adjusted to be a mute mode; or the right ultrasonic output module of the middle display is used as a right sound channel speaker of the display device, and the left ultrasonic output module is used as a left sound channel speaker of the display device. The display assembly and the sound channel setting of the ultrasonic output module are not limited to the foregoing embodiments, and are determined according to actual requirements, and will not be described in detail herein.
In summary, the ultrasonic wave has strong penetration, as long as it is ensured that there is no solid or densely wired metal material in front of the ultrasonic wave output module, the acoustic signal of the ultrasonic wave output module can penetrate through a display panel with a considerable thickness, and the optical characteristics of the display panel are not affected. The ultrasonic output module can be a cylinder type, a flat plate type, a thin film type or a micro-electromechanical type transmitter. Each display can be provided with one or more ultrasonic output modules, and the plurality of displays can be spliced along various directions to form a wide-screen display device; the number of displays and the manner of splicing are not limited to those described in the foregoing embodiments. When a plurality of displays are used in a splicing manner, the ultrasonic output module of each display can set the required output options according to the corresponding installation position, such as a left channel, a right channel, a single channel or a mute mode.
The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above.
