Problems solved by technology

[0012] In addition, when the sound generated from the speaker 2 travels toward the rear or lower portion of the display panel, the sound quality is degraded due to the interference of sound reflected by the wall, the floor, or other surfaces located behind or below the display panel.
[0013] In addition, the sound generated by the speaker included in the display device of the related art is not directed toward the viewer of the display device, and thus may undergo diffraction, which deteriorates sound localization.
Also, when constituting unit equipment such as a TV, speakers may occupy an undesirably large amount of space, which imposes constraints on the design and space configuration of the unit equipment

Abstract

Disclosed is a display device that includes a display panel (100), sound generating actuators including a first sound generating actuator (200) in a first area of the display panel and a second soundgenerating actuator (200') in a second area of the display panel, the first and second sound generating actuators configured to vibrate the display panel to generate stereo sound, and a partition (600) between the first sound generating actuator (200) and the second sound generating actuator (200').

Description

technical field [0001] The present disclosure relates to a display device, in particular to a display device that generates 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 applicable thereto has gradually increased. Display devices include electroluminescent display devices, liquid crystal display devices, light emitting diode display devices, and organic light emitting diode display devices. [0003] Among these display devices, a liquid crystal display (LCD) device generally includes: an array substrate having an array of thin film transistors; an upper substrate having a color filter layer and / or a black matrix, etc.; and a liquid crystal material layer formed therebetween, Among them, the alignment state of the liquid crystal is controlled according to the electric field applied between two electrode...
