Embodiment Construction

[0036] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements.

[0037] As used herein, "connection" may refer to physical and / or electrical connection (coupling), and the electrical connection (coupling) may have intervening elements.

[0038] As used in this article, "Sound Loudness" refers to the perception of sound volume, for example, the sound intensity felt by the user's ears. Loudness includes at least two aspects. One is the sound loudness level (Sound Loudness Level), and the unit is Feng (phon), the other is the loudness of the sound, and the unit is Sone. The unit of perceptual quantity covered is not limited to phon, pine or decibel, and other perceptual quantities referring to the magnitude of sound should also be covered by the present invention.

[0039] As used herein, "about," "approximately," or "substantially" includes stated va...

Abstract

A display device and its driving method. The display device includes a display panel, a sound module, an image analysis circuit and a sound drive circuit. The display panel has a plurality of display units. The sounding module has a plurality of sounding elements, which are at least one-to-one corresponding to the display unit. The image analysis circuit receives the image signal for analyzing the position of the sounding object in the display screen, and correspondingly provides sounding information. The sound driving circuit judges the first display unit of the display unit overlapping with the sounding object according to the sounding information, and adjusts the loudness of the sounding element corresponding to the first displaying unit.

Description

technical field [0001] The present invention relates to a display device and its driving method, and in particular to a display device and its driving method which can emit sound by using the sound-generating elements in the display panel. Background technique [0002] With the advancement of electronic technology, display devices have become an indispensable tool in people's lives. In order to provide a good man-machine interface, a high-quality display panel has become a necessary device in a display device. [0003] In an existing display device, a designer usually presents a display image to be displayed through a display panel, and outputs a sound corresponding to the display image through a speaker mounted outside the display panel. That is to say, the display screen and the corresponding sound are respectively output through different transmission paths. In this case, when the user watches through the display device, the user will lack a sense of presence, and the s...
