Abstract
(EN)
See-through, touch-sensitive displays are provided. More particularly, in some embodiments, apparatuses are provided, comprising: a controllable transmittance film; a transparent display panel; a clear panel; a touch sensitive overlay; and a hardware processor coupled to the controllable transmittance film, the transparent display panel, and the touch sensitive overlay, and configured to cause the controllable transmittance film to switch between a first state in which the controllable transmittance film is non-energized and a second state in which the controllable transmittance film is energized. In some of these embodiments, the transparent display panel is positioned between the controllable transmittance film and the clear panel. In some of these embodiments, the clear panel is positioned between the transparent display panel and the touch sensitive overlay. In some of these embodiments, the apparatus is positioned on a vending machine. In some of these embodiments, the apparatus is positioned on a refrigerator.

L'invention concerne des unités d'affichage tactiles transparentes. Plus particulièrement, certains modes de réalisation concernent des appareils comprenant : un film à transmittance pouvant être commandée; un panneau d'affichage transparent; un panneau clair; un revêtement tactile; et un processeur matériel couplé au film à transmittance pouvant être commandée, au panneau d'affichage transparent, et au revêtement tactile, et conçu pour amener le film à transmittance pouvant être commandée à alterner entre un premier état dans lequel le film à transmittance pouvant être commandée est non excité et un second état dans lequel le film à transmittance pouvant être commandée est excité. Selon certains de ces modes de réalisation, le panneau d'affichage transparent est positionné entre le film à transmittance pouvant être commandée et le panneau clair. Selon certains de ces modes de réalisation, le panneau clair est positionné entre le panneau d'affichage transparent et le revêtement tactile. Selon certains de ces modes de réalisation, l'appareil est positionné sur un distributeur automatique. Selon certains de ces modes de réalisation, l'appareil est positionné sur un réfrigérateur.
