Abstract[English]
Disclosed in the present invention are a highly reliable touch display directional sound production device and a manufacturing process therefor. Said device comprises a vibrating layer and a non-vibrating layer a frame of which is attached to a frame of the vibrating layer. The manufacturing process comprises: on an existing touch control and OLED display module, manufacturing a flexible cover plate and an upper trace of a sound-production layer, so as to form a vibrating layer; using a flexibly foldable UTG as a substrate layer of a non-vibrating layer, and on the UTG substrate layer, forming a microstructure, a second conductive layer and an insulating dielectric layer that constitute a lower trace of the sound-production layer, so as to form a non-vibrating layer; and finally, attaching the frame of the vibrating layer to that of the non-vibrating layer, so as to finally form a touch display directional sound production device that integrates multiple functions such as foldability, touch control, directional sound production and OLED display, which has diversified functions and good application prospects.[French]
La présente invention concerne un dispositif de production de son directionnel d'affichage tactile hautement fiable et son procédé de fabrication. Ledit dispositif comprend une couche vibrante et une couche non vibrante dont un cadre est fixé à un cadre de la couche vibrante. Le procédé de fabrication comprend les étapes suivantes : sur un module d'affichage à commande tactile et OLED existant, fabriquer une plaque de recouvrement souple et une trace supérieure d'une couche de production de son, de façon à former une couche vibrante ; utiliser une UTG pliable de manière flexible en tant que couche de substrat d'une couche non vibrante, et sur la couche de substrat UTG, former une microstructure, une seconde couche conductrice et une couche diélectrique isolante qui constituent une trace inférieure de la couche de production de son, de façon à former une couche non vibrante ; et enfin, fixer le cadre de la couche vibrante à celui de la couche non vibrante, de façon à former finalement un dispositif de production de son directionnel d'affichage tactile qui intègre de multiples fonctions telles qu'une pliabilité, une commande tactile, une production sonore directionnelle et un affichage OLED, qui a des fonctions diversifiées et de bonnes perspectives d'application.[Chinese]
本发明公开了一种高可靠性的触控显示定向发声装置及其制备工艺，所述装置包括振动层和与振动层相边框贴合的非振动层，其中，通过在现有触控及OLED显示模组上做柔性盖板和发声层上线，从而形成振动层；并采用柔性可折叠的UTG作为非振动层的基材层，通过在UTG基材层上形成构成发声层下线的微结构、第二导电层和绝缘介质层，形成非振动层；最后通过将振动层和非振动层的边框相贴合，最终形成集可折叠、触控、定向发声和OLED显示等多种功能于一体的触控显示定向发声装置，功能多样，具有很好的应用前景。
