Abstract

The invention provides a screen sounding unit, a manufacturing method thereof and a display device. The screen sounding unit comprises a display panel, a plurality of exciters and a driving unit. Eachexciter is arranged on one side of the non-display surface of the display panel, each exciter comprises magnets and a voice coil, the magnets in the exciters are configured to generate magnetic fieldforce between the magnets with opposite magnetisms, and voice coils are driven to vibrate in the direction perpendicular to the display panel; the driving unit comprises a wiring layer and an audio control circuit; audio control lines are distributed on the wiring layer; the wiring layer is integrated on the non-display surface of the display panel; the screen sound production unit comprises a plurality of sound production areas, at least one exciter is arranged in each sound production area, the exciter in each sound production area is correspondingly connected with the audio control line inthe sound production area, and the exciters in different sound production areas apply audio signals independently. According to the screen sounding unit, the manufacturing method thereof and the display device, regional sound production is achieved, the structure is compact, and more integrated and miniaturized design is achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a screen sound unit, a manufacturing method thereof, and a display device. Background technique [0002] The ultra-thin, narrow bezel, and even full-screen designs of display devices leave less and less space for sound-generating devices. However, the traditional sound generating device has a large volume and its installation position is limited, so it is difficult to have a suitable position and space in the new generation of display devices. Therefore, it is necessary to redesign the sound generating device that can adapt to the requirements of the current display device. At present, in an OLED (Organic Light-Emitting Diode) display, a display device that uses the entire screen as a diaphragm to realize sound emission has appeared. In this design, the display device directly emits sound to achieve sound and picture synchronization, which can effectively use space and save re...
