Embodiment 1

[0093] In this embodiment, the screen sounding device may include a display panel configured to display images, and a screen sounding drive part configured to contact the back of the display panel and vibrate the display panel to generate sound.

[0094] The display panel used in this embodiment can be any type of display panel, such as a liquid crystal panel, an organic light-emitting diode display panel, etc., and is not limited to a specific display panel technology, as long as the display panel can generate vibration due to the screen sound driver. Sonic or audible output.

[0095] For example, if the display panel is a liquid crystal panel, the display panel may include an array substrate including a plurality of gate lines, a plurality of data lines, and a plurality of pixels at or near intersection regions of the gate lines and data lines, and a thin film transistor used as a switching element configured to adjust light transmittance at each pixel; an upper substrate in...

Embodiment approach

[0130] As an optional implementation manner, the screen sound driver 204 includes a first frequency band sound driver and a second frequency band sound driver;

[0131] The first frequency band sound driver is used to use the virtual first frequency band signal to drive the display panel to vibrate and sound;

[0132] The second frequency band sound driver is used to use the second frequency band signal to drive the display panel to vibrate and sound.

[0133] The screen sound driver deforms under the driving of the output signal, and then drives the display panel to vibrate and sound.

[0134] As an optional implementation, such as Figure 5A As shown, the first frequency band sound driver includes a first frequency band sound driver 301, and the second frequency band sound driver includes two second frequency band sound drivers 302;

[0135] The first frequency band sound driver 301 is located on the vertical center line of the display panel and is closer to the bottom of ...

Embodiment 2

[0194] This embodiment also provides a screen sounding device, such as Figure 10 As shown, it includes a memory 1001 and a processor 1002, wherein the memory 1001 is used to store programs executable by the processor 1002, and the processor 1002 is used to read the programs in the memory 1001 and execute the following process:

[0195] Acquiring a first frequency band signal whose frequency is within a first threshold range, and a second frequency band signal whose frequency is within a second threshold range, where the frequency minimum value of the second frequency band signal is higher than the maximum value of the first frequency band signal;

[0196] After the first frequency band signal is harmonically enhanced, it is mixed with the second frequency band signal to generate a virtual first frequency band signal;

[0197] The display panel is driven to vibrate and sound according to the virtual first frequency band signal and the second frequency band signal.

[0198] A...

Abstract

The invention discloses screen sounding equipment and a screen sounding method, which solve the problem of poor bass sounding effect of the existing screen sounding equipment, and comprise a display panel and the following parts positioned at the back of the display panel: a first filtering channel used for acquiring a first frequency band signal of which the frequency is within a first thresholdrange; the second filtering channel is used for acquiring a second frequency band signal of which the frequency is within a second threshold range, and the minimum frequency value of the second frequency band signal is higher than the maximum frequency value of the first frequency band signal; the virtual first frequency band signal generator is used for carrying out harmonic enhancement on the first frequency band signal and then mixing the first frequency band signal with the second frequency band signal to generate a virtual first frequency band signal; and the screen sounding driver is used for driving the display panel to vibrate and sound by utilizing the virtual first frequency band signal and the second frequency band signal.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a screen sound generating device and method. Background technique [0002] With the development of various electronic devices such as mobile communication terminals, notebook computers and flat-screen TVs, as the thickness and frame of these electronic devices become narrower, users have more and more requirements for the appearance, size and performance of these electronic devices. high, and the demand for display devices suitable for them is growing. [0003] The speaker of the display device in the prior art is arranged at the rear or the lower part of the display panel. In this configuration, the sound generated by the speakers does not travel directly towards the viewer viewing the image from the front of the display unit, but rather towards the rear or lower part of the display panel, resulting in a lack of directionality in the sound emission and only eman...
