Title:
ULTRA-THIN VIBRATION GENERATION MODULE USING BEAT-FREQUENCY ELECTRIC FIELD, VIBRATION GENERATION METHOD, AND DISPLAY DEVICE INCLUDING VIBRATION GENERATION MODULE
Document Type and Number:
WIPO Patent Application WO/2017/142307
Kind Code:
A1
Abstract:
The present invention relates to an ultra-thin vibration generation module using a high-voltage beat-frequency electric field, a vibration generation method, and a flexible display device including the ultra-thin vibration generation module. More specifically, the present invention relates to an ultra-thin vibration generation module using a high-voltage beat-frequency electric field, and to a flexible display device including the ultra-thin vibration generation module, the ultra-thin vibration generation module comprising: a beat-frequency electric field generator for generating a beat-frequency electric field, the beat-frequency electric field generator including an electrode substrate for generating beat-frequency electricity and an electrode part having first and second electrodes spaced apart from each other by a particular distance so as to be insulated from each other, wherein the first electrode is attached to one surface of the electrode substrate and receives a first voltage with a first frequency, and the second electrode receives a second voltage with a second frequency different from the first frequency; a vibration amplification member spaced apart from the beat-frequency electric field generator by a particular distance and amplifying vibration generated by the beat-frequency electric field generator; and an outer spacer disposed between the vibration amplification member and the beat-frequency electric field generator to allow the vibration amplification member and the beat-frequency electric field generator to be spaced apart from each other by the particular distance.
