Display device including a multifunctional and communicating surface

摘要

The invention relates to a display device including a plurality of pixels forming an image, and an optical plate arranged opposite the image and having transparency areas configured to allow the light from the pixels to at least partially pass therethrough. The optical plate further includes at least one array of functional elements corresponding to an electronic and/or mechanical function. The functional elements are inserted between the transparency areas and arranged such that the light emitted by the pixels is directed so as to pass through the transparency areas without intercepting the arrays of functional elements, so as to render the arrays of functional elements invisible or quasi-invisible to an observer of the display device. The invention can be used in any type of display device in which functions other than display itself must be integrated in a visually discreet manner.

主权项

1. A display device comprising:
a plurality of pixels forming an image, and an optical plate arranged facing the image and including areas of transparency configured to allow at least part of the light from the pixels to pass, wherein said optical plate also includes at least one electrical network of functional elements, which are not transparent to the visible light, and which include sensors and/or transducers configured to execute electronic and/or mechanical functions, wherein said functional elements are inserted between the areas of transparency and are arranged in such a way that the light emitted by the pixels is directed to pass through the areas of transparency without intercepting the networks of functional elements, so as to render said networks of functional elements invisible or quasi-invisible to an observer of the display device, although they are non-transparent, and wherein said electrical network of functional elements includes antenna configured in the form of a flat spiral electrical conductor which leaves a plurality of spaces of transparencies placed in front of a network of lenses also included in the optical plate.
