## Abstract

A ventilated multilayer dynamic digital filter for photovoltaic panels includes a LED front panel, an intermediate panel having a photovoltaic surface, and a rear panel, the panels indirectly overlapping each other so that interspaces are created between the panels which are configured to allow the heat to circulate within the digital filter. Described herein is also the use of the digital filter for exterior cladding of facades and/or roofs of buildings, with the possibility of changing the patterns/textures of the cladding and improving the energy efficiency of a building.

## Claims

### Claim 1

A ventilated multilayer dynamic digital filter for photovoltaic panels, comprising a LED front panel, an intermediate panel comprising a photovoltaic surface, and a rear panel, said panels indirectly overlapping each other so that interspaces are created between said panels which are configured to allow the heat to circulate within the digital filter.

### Claim 2 (depends on 1)

The ventilated multilayer dynamic digital filter for photovoltaic panels according to claim 1, wherein the front panel comprises a semi-transparent LED screen that comprises a LED grid or a series of parallel LEDs, the empty spaces in the LED grid or between the series of LEDs being configured to allow the light to pass through the front panel and hit the photovoltaic surface of the intermediate panel without affecting the perception of the images reproduced on the front panel.

### Claim 3 (depends on 2)

The ventilated multilayer dynamic digital filter for photovoltaic panels according to claim 2, wherein the percentage ratio between the empty spaces and the spaces occupied by the LEDs of the semi-transparent LED screen is between 30% and 95%.

### Claim 4 (depends on 1)

The ventilated multilayer dynamic digital filter for photovoltaic panels according to claim 1, comprising a frame positioned on the perimeter of each panel , the frame of the front panel being in contact with the frame of the intermediate panel, which in turn is in contact with the frame of the rear panel, so as to create the interspaces between the panels.

### Claim 5 (depends on 1)

The ventilated multilayer dynamic digital filter for photovoltaic panels according to claim 1, wherein the frames of the front panel in contact with each other are connected by means of hinges, so that it can be opened like a book in order to inspect the interspaces between the panels.

### Claim 6 (depends on 1)

The ventilated multilayer dynamic digital filter for photovoltaic panels according to claim 1, wherein the front panel may be made of shatterproof transparent material, so as to make the structure of the filter sufficiently strong for roof or ground installation.

### Claim 7 (depends on 1)

A use of the ventilated multilayer dynamic digital filter for photovoltaic panels according to claim 1 for exterior cladding of facades and/or roofs of buildings, with the possibility of changing the patterns/textures of the cladding and improving the energy efficiency of a building.
