VIDEO DISPLAY SYSTEM ON GLASS SURFACES

OBJECT OF THE INVENTION

The present invention refers to a system for displaying images, issued on a digital support, on a glass surface where the images are reflected, the glass surface becoming the place where the images on the digital support are reproduced, creating an effect very impressive when recreating video content on non-electronic glass surfaces.

It finds special application in the field of industry related to video broadcast systems.

BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEM TO BE RESOLVED

In the current state of the art, developments have been made related to the integration of digital technologies in the architectural elements of buildings.

Contemporary architecture is undergoing a transformation process due to the development and integration of digital technologies in construction processes; a process that evokes that which took place during the industrial revolution, which crystallized in modern architecture.

In addition to transforming material production processes, technological development entails changes in the concepts that determine the aesthetic value of architectural works.

The research starts from the premise that architecture is in a period of transition in full effervescence, a period that can be understood as a state of flux, a becoming. In this context of change, an analysis focused on the current state of architecture runs the risk of quickly becoming obsolete, since any technique, tool or theory related to digital design and manufacturing processes can being outpaced by the speed of technological change.

LED screens and digital monitors are audiovisual elements that are difficult to integrate into architecture, which is why this invention seeks integration through noble materials, such as glass, through which surprising audiovisual effects are achieved that are enhanced by the materials themselves. .

The present invention is based on the use of glass surfaces placed in front of a digital video emitter or digital support. The interposition of this material achieves visual effects where the glass itself becomes the surface on which the images of the digital elements created for audiovisual support (content / videos) are transmitted, even achieving buoyancy and holographic effects on the screen. glass surface.

This use of glass is due to the great possibilities that this material offers in terms of visualization due to the enormous number of properties and technical characteristics with which it can act.

The main glass properties that can be worked with are listed below:

- Light visibility, considering the properties of transmission, as a percentage of visible light that is transmitted directly through the glass, reflection, as a percentage of reflected visible light, and the index of color variation (CRI), as the capacity of light natural, transmitted through the glazing, to represent a range of colors compared to those seen under natural light without glazing. A scale of 1 to 100 is used. A low CRI makes colors appear washed out, while a high CRI (greater than 85) makes them appear vivid.

- Capture of Solar Energy, considering transmission, reflection and absorption properties.

- Solar Factor, in terms of the percentage of solar energy transmitted through the glass. Measures the ability of a glass to reduce heat input. The lower the solar factor, the lower the heat input.

-Value U, as the measure of heat flux that is transferred through the glazing.

- Selectivity. It is the relationship between light transmission and solar factor. The higher the ratio, the greater the comfort in the buildings. If this ratio is greater than 2, the glass allows twice as much light to pass through as heat.

The studies carried out on these properties have determined that the U value, the solar factor and the selectivity do not influence variations in the viewing conditions of the retransmissions broadcast on the digital support. As for the rest, the following has been determined:

- the light transmission must have a value as low as possible,

- the reflection has to be as low as possible,

- The IRC color variation index must be as close as 100 so that the holograms appear with the original color of the digital medium that emits them.

The present invention has analyzed these parameters of glazed surfaces with the intention of obtaining visualization effects not shown in the state of the art up to now in order to ensure that a video recording reproduced on a digital medium can be viewed on a glazed surface.

DESCRIPTION OF THE INVENTION

In order to achieve the objectives and avoid the drawbacks mentioned above, the present invention describes a system by which a video playback on an electronic screen is perceived on a glass surface as an element with a striking effect and integrated with the architecture. In addition, the visual effects created are enhanced in such a way that they can present buoyancy and holographic effects on the surface of glass materials. For this, a glazed surface is selected with a series of technical characteristics that are studied to combine them with an additional characteristic, such as the distance at which the glazed surface of a digital support is placed where video content is being broadcast.

The fundamental elements of the invention are the following:

- a digital content intended to be reproduced,

- a digital medium where the digital content is broadcast,

- a glazed surface, intended to be placed in front of the digital support, and

- Separating elements, intended to locate the glazed surface at a certain distance from the digital support.

The digital content includes black/color colorimetry, so that images with high contrast are obtained.

The digital medium is a digital video playback screen such as an industrial LED screen, professional video monitors, or a television.

The reproduction of the video content of the digital support on the glass surface does not imply that the entire glass surface receives the broadcast. In this way, it is possible to emit the digital content to be reproduced on the glazed surface in a certain part of the glass surface, making the rest of the glass remain with the same image it had in a passive state.

The glazed surface is a material with certain specifications in terms of visible light transmission and external reflection.

These specifications are preferably in the following ranges:

- visible light transmission: between 10% and 30%, more preferably between 15% and 25% and optimally between 19% and 22%, and

- external reflection: between 5% and 35%, more preferably between 5% and 25% and optimally between 10% and 24%.

Lastly, as regards the separator elements, they ensure that the glazed surface is positioned in front of the digital support at a distance of less than 999 millimeters, preferably less than 730 millimeters and, optimally, at a distance of less than 375 millimeters. One way to position the separating elements is by incorporating a frame in which the digital support is housed.

One way to position the glass surface is by using a frame in which the digital support is housed in a fixed manner. The spacer elements can then be fixed to the frame and to the glazed surface by ways known in the state of the art, so that the glazed surface is positioned with respect to the digital support at the selected distance in a way that can be adjusted.

It should be noted that the type of glass surface used, as well as the technical specifications and the location distance from the digital support has involved trial and error until the final selection was determined.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

Figure 1 represents the image display system of the invention.

The system is composed of the following elements, as represented in figure 2:

- A digital support (1), where video content is broadcast with the images to be viewed,

- A glazed surface (2), intended to be placed in front of the digital support to create a screen,

- Some separating elements (3) by means of which to maintain the distance between the glazed surface (2) and the digital support (1),

- A frame (4), designed to locate the digital support (1) and act as a base for the location of the separator elements (3) at one end.

Figure 1 represents a digital support (1) located in a frame (4) on which spacer elements (3) have been fixed at one end. The other ends of the separator elements (3) are fixed to a glass surface (2) so that it is stably fixed at a distance from the digital support (1). The frame (4) is a known element whose only function is to fix it to the digital support (1) and act as a location for fixing the separator elements (3) for the subsequent location of the glazed surface (2).

The separating elements (3) are fixed, although they preferably allow the glass surface (2) to be located at an adjustable distance from the digital support (1). This regulation is carried out by known means, such as, for example, using threaded rods with nuts.

The digital support (1) used is an LED television screen.

For the selection of the glazed surface (2), tests were carried out with a wide range of crystals to determine the characteristics provided in terms of light transmission and reflection.

The following table specifies a selection of the different types of glass tested.

Through the tests and studies carried out, it was concluded that the transmission value should be in the range of 10-30%, while the reflection should be in the range of 10-35% and the ICR should be be in values higher than 85%. From this study it is concluded that the materials that meet the needs in terms of transmission, reflection and ICR are those detailed in the previous table.

Once the glazed surface (2) has been determined, the next element to select consists of the length of the separator elements (3), that is, the distance at which the digital support (1) must be placed. After carrying out a series of tests, it was concluded that the optimum distance to obtain the desired effect was achieved when the digital support (1) was placed at 375 mm or less from the glass surface (2).

In the present embodiment, the separator elements are sized to achieve a separation between the glass surface (2) and the digital support (1) of 350 millimeters.

Finally, the digital content that is reproduced on the digital support (1) is a 2D recording with black/color colorimetry with high contrast images. In this way, the selected configuration allows, by placing the digital support (1) at a distance of less than 375 mm from the glass surface (2), to achieve the objective of being able to visualize in 3D the content that was being reproduced on the digital support (1).

In addition to being able to reproduce the content of the digital support (1) on the glazed surface (2), it is also possible to ensure that the images are transmitted to a certain area of the glazed surface (2), even presenting holographic or three-dimensional effects while the rest of the glass remains in its natural state.
