Problems solved by technology

[0008] Also, when the sound generated from the speaker 2 travels toward the rear or lower portion of the display panel, the sound quality may degrade due to interference with sound reflected by the wall, floor, or other surface behind or below the display panel.
[0009] Furthermore, the sound generated by speakers included in prior art display devices is not directed towards the viewer of the display device and thus may experience diffraction, which reduces sound localization
Furthermore, when configuring a kit such as a TV, speakers may occupy an undesirably large amount of space, which imposes constraints on the design and spatial arrangement of the kit

Abstract

A display device includes a display panel having first, second, and third areas; at least three sound generating actuators including first, second, and third actuators each spaced apart from the othertwo in a long axis direction of the display panel, wherein the first, second, and third actuators each contact the display panel at the first, second, and third areas respectively to generate sound by vibrating the display panel; and a support structure arranged at a rear side of the display panel and configured to support the at least three sound generating actuators.

Description

technical field [0001] The present disclosure relates to display devices, and more particularly, to display devices that generate sound by vibrating a display panel. Background technique [0002] With the development of various portable electronic devices such as mobile communication terminals and notebook computers, the demand for display devices suitable for them is increasing. [0003] Display devices include liquid crystal display devices, electroluminescent display devices, light emitting diode display devices, and organic light emitting diode display devices. [0004] Among these display devices, a liquid crystal display (LCD) device generally includes: an array substrate including a thin film transistor array, an upper substrate including a color filter layer and / or a black matrix, etc., and a liquid crystal material layer formed therebetween, wherein, according to An electric field applied between two electrodes in the pixel area controls the alignment state of the ...
