Title (EN) TOUCH-SENSITIVE ILLUMINATING DISPLAY
(FR) AFFICHEUR TACTILE À ÉCLAIRAGE
Abstract:
(EN) In an example implementation, a touch-sensitive illuminating display includes a transparent flexible touch layer, a transparent top conductive layer adjacent the flexible touch layer, a bottom conductive layer, and an electroluminescent layer and variable-thickness dielectric layer sandwiched between the top and bottom conductive layers. Pressure against the flexible touch layer is to reduce the dielectric layer thickness and bring the top and bottom conductive layers closer together, causing the electroluminescent layer to emit light where the pressure is applied.
(FR) Dans un mode de réalisation décrit à titre d'exemple, un afficheur tactile à éclairage comprend une couche tactile souple transparente, une couche conductrice supérieure transparente adjacente à la couche tactile souple, une couche conductrice inférieure, ainsi qu'une couche électroluminescente et une couche diélectrique d'épaisseur variable prises en sandwich entre les couches conductrices supérieure et inférieure. Une pression contre la couche tactile souple a pour effet de réduire l'épaisseur de la couche diélectrique et de rapprocher les couches conductrices supérieure et inférieure l'une de l'autre, amenant la couche électroluminescente à émettre de la lumière là où la pression est appliquée.
