Panel vibration type sound generating display device

Abstract

The invention relates to a display device. The display device comprises a display panel, which is configured to display images; a plurality of sound generation exciters, which are arranged in a plurality of sound outputting areas and are configured to vibrate the display panel to generate sounds; and partition parts, which are arranged between every two sound outputting areas and surround at leastone of the sound outputting areas.

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.

[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 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 ...
