Title:
PREPARATION PROCESS FOR TOUCH SOUND PRODUCTION DISPLAY UNIT
Document Type and Number:
WIPO Patent Application WO/2023/226761
Kind Code:
A1
Abstract:
A preparation process for a touch sound production display unit, comprising: processing one side between a first substrate (1) and a second substrate (4) to form a touch structure of a touch area (3), and processing the other side to form a sound production structure of a sound production area (2); and performing full lamination on the first substrate (1) and the second substrate (4) located in the touch area (3), and performing frame lamination on the first substrate (1) and the second substrate (4) located in the sound production area (2). According to the preparation process, an electrostatic ultrasonic transducer is combined with a touch screen, so that directional sound production on the screen can be implemented on one side of a display device, touch can be implemented on the other side, and the two sides do not interfere with each other. While achieving directional sound production on the screen, private listening and avoidance of interference to surrounding personnel, the display device can also have a touch function, thereby expanding the application range thereof.
