Description

DESCRIPTION

Image screen backlit by hydrogen fusion light, sunlight Abbreviations: Solar Quantum TV, Fusion Screen, Echo Fusion TV

Technical Sector

Ecological Retro Lighting, by means of Solar Light from an image screen, TV or advertisement screen.

Background of the Invention

History of backlight systems known and marketed on a large scale throughout the world:

An LCD screen liquid crystal display: "liquid crystal display" for its acronym in English. It is a thin, flat screen made up of a number of color or monochrome pixels placed in front of a light source or reflector. It is often used in electronic devices as it uses very small amounts of power.

It is present in a number of devices, from the limited image shown by a pocket calculator to televisions of 80 inches or more. These screens are made up of thousands of tiny helical liquid crystals, which are neither solid nor Liquid in reality, but an intermediate state. That control the intensity, and what color of light they let through for each pixel, the sum of these in a synchronized way with the original exploration will reproduce the images.

In recent years, two groups of white light sources used to backlight large LCD panels have become popular and marketed.

The first is formed by a panel of several tubes or cold cathode Fluorescent lamps, which contain Mercury. For their operation they need a high voltage power supply. And its power consumption is relatively high. Over time they age and change the intensity and color spectrum of light that they contribute to the ^l C ^d . Some of these fluorescent lamps are in varying amounts dotted directly behind the LCD. Other models are arranged on the edges of an acrylic or similar plate that spreads the light throughout the LCD.

The second system is the one that uses solid-state lamps that are actually light-emitting semiconductor diodes, LEDs. These are generally used in large numbers directly behind the LCD, separated from it by diffuser sheets to achieve even, homogeneous light. In other screens, the LEDs are grouped very close to each other in strips placed on the edges of an acrylic plate or similar that distributes the light throughout the LCD. Generally they work very demanding raising temperature. They require a heat sink and their useful life is short.

Although Led screens are called low energy consumption, in large screens for home use or advertising in public spaces, their electricity consumption is high. For example, a 40-inch TV consumes 75 Watts. Consumption increases proportionally to the size of the screen because more diodes are required to provide enough light. 80 to 90% of that consumption belongs to backlighting. A large percentage of the failures of LCD television screens or advertising screens or advertisements are attributed to failures in the backlighting system, which generally ends the useful life of that device. Generally, the color spectrum of fluorescent tubes and LEDs is not very linear. Noting that in such devices many wavelengths have high gain and quickly drop off sharply at other frequencies in the near spectrum. See figures 29 and 38. In addition, the light flow of these lighting systems is generally pulsating, that is, they have low-frequency flickering. Also some of these systems emit a lot of blue light.

Explanation of the invention

The present disclosure It is about a Screen that as a whole could be called Hybrid, reproducing Images. Of Dimensions that vary from the sizes suitable for home, commercial and Large street advertising screens and Large Route or highway signs.

Noting the absence in the market of a screen that is ecological, in the sense that it is reduced in electrical consumption and also less aggressive in unwanted radiation or harmful to vision. That it can have a naturalness to reproduce colors more in line, or real to the objects that are directly observed by our eyes in everyday life.

This lack of technology in ecological images and more natural colors was the incentive for the activity to carry out a new concept of Image screens. Current technology in image screens, added to the "natural technology" that surrounds us and forms an essential part of our lives, results in a backlit image screen generated by the fusion of hydrogen from the Sun. Since it has a chromatic spectrum of excellent linearity and constancy. That is, it is not pulsating with low frequency like other systems mentioned. In addition, the Sun naturally illuminates most of the vision that humans have and that they often try to reproduce on image screens. For example, an image taken by a camera in a green meadow with multi-colored flowers, illuminated by sunlight, can by this system be reproduced on a screen with the same light source as the original object. So Solar Light, Hydrogen Fusion Light Backlighting for Imaging Displays is an economical, durable and excellent light for backlighting an LCD Display, or other non-light emitting or translucent imaging panel. You can also backlight an image panel so that its cells or pixels emit their own light to form images at one time and form translucent images that require backlighting at another time.

Depending on the power of solar light energy available at the time or the characteristics of the day, this backlighting can be powered by the side edges, bottom side, top side or by direct incidence of sunlight on a light-permeable sheet arranged on the back of image panel. Part of the inventive activity results in the elimination of any opaque surface on the back of an image panel, replaced by a translucent diffusing sheet that allows the incidence of ambient light as a source of Backlighting scattered light that falls on the entire part opposite to the output surface of images, retro lighting, such as sunlight coming from an opening, window, door. Floor, ceiling or partition of an enclosure or room. This device can be used alone or simultaneously and alternately with a plurality of solar and artificial backlighting systems. For example, a light projection or illuminator device can also be used on any of the 4 edges of the image panel, which has a rectangular panel and a triangular finish made of solid light-conducting material that can contain one or more mirrors that form a surface. placed at an appropriate angle that reflects the received light remotely, to the back of the image panel, which can be an LCD Display or other image panel whose pixels emit or do not emit their own light and or that are translucent at another time and require backlighting. This device has an optical connector, which receives light through a fiber optic conductor that comes from a solar light concentrator formed by circular solid cylinders, transparent that conduct sunlight, these on its upper face have a slit in the form inverted cone. This conical upper surface has a polarized paint or film that produces a downward mirrored surface on its lower face. Translucent from the upper face to the lower by 80%. At the lower side angle of this cone and axis of the cylinder comes out the optical conductor, which feeds the screen lighting device. Light can enter the cylinder at the top surface of the cone and be concentrated at the apex and exit through the optical conductor. Light can also enter through the walls of the circumference and be reflected towards the center of the cone by the lower mirrored side, concentrating at the vertex and exiting through the optical conductor to feed the screen illuminator device.

In addition to those mentioned, another source of Solar Backlighting is detailed that can be mounted on the lower, side or upper edge of the back of the image panel, which can be an LCD Display, or another image panel that does not emit light or translucent You can also backlight an image panel so that its cells or pixels emit their own light to form images at one time and form translucent images that require backlighting at another time.

This solar light power supply can be for a self-supporting, waterproof imaging panel located outdoors that receives or is backlit by incident sunlight. For example, a notice board visible from public roads. In this particular case, this lighting source consists of an elongated cylinder of the same length as the edge of the screen in which it is located. This solid, transparent and light-conducting cylinder can be arranged horizontally or vertically. Contains two mirrors on the bottom or side of the imaging panel, AND an 80% translucent mirrored or polarized surface on the top or opposite side of the imaging panel This cylinder on the bottom or side of the imaging panel is bonded and connected in optically to the backlight panel of the imaging screen. Sunlight falls on the cylinder in two ways. One is for the 2 side surfaces without mirrored film and through reflections in the interior mirrors to influence the output optically connected to the retro-illuminating panel. The other is by direct incidence on the upper or opposite surface of the image panel, passing through the mirrored or polarized film. Bringing sunlight directly, or by reflection from mirrors, to back-illuminate the image panel. Something Innovative Is that when it uses sunlight to backlight an image-reproducing screen during daylight hours, it will only use electrical power for the main motherboard, Tcon board and Led, but not for the LEDs or electronic backlighting systems or emitting pixels. of Light That can be backlit when sunlight is available. This is very important when there is no electricity distribution network available and this is generated with low-production means such as solar panels for electricity.

In practice, it was observed that the colors are more natural and that as the environment is also illuminated by daylight, without blinking, prolonged viewing was less tiring to the eye.

Preferred embodiment of the invention

Prototype

The present disclosure was tested for operation by making a Prototype. Using a Liquid Crystal Display and Motherboard of a conventional 40-inch Led TV model KDL40w 475 with original consumption of 75 Watts on a supply voltage of 18.5 Volts. But it can be done easily using any LCD Imaging panel that detaches from a distribution TV on the market. Large-scale production of a variety of large screens for various uses backlit by sunlight is feasible. With production systems this Invention could be manufactured economically and durably. With a very wide field of applications.

In this case, the TV's original LED panel was discarded along with its driver IC. Behind the LCD, a 4-millimeter-thick Acrylic Plate was used -fig.7- on which a transparent sheet printed with small white circles separated from each other by a distance similar to the diameter of each circle was glued to one of its faces. Conventional LED diodes were placed on its lateral edges -fig.1-. To restore a normal backlight by electricity. A thin white light-permeable sheet was placed behind this acrylic -fig.8-. A variant of placing a light-permeable white self-adhesive sheet, glossy on the acrylic side and matte on the sunlight entry side, was also made. In this case it was not necessary to place the printed sheet with circles mentioned above. By this means the panel, when operating with the LED light, could be reflected in the bright white, and when it was illuminated by sunlight it would be entering through the matte face and reflecting on the bright face.

The LED diodes were connected in series with a switching transistor to turn them on or off depending on a key and/or a circuit associated with a photocell -fig.23-. That determines the level of natural light in the room where the TV is located. This circuit has a potentiometer -fig.20- that allows you to choose the minimum level of natural light to turn on the side lighting LEDs (Twilight Control). The LCD, main board, and Tcon board were mounted on high-strength aluminum frames -fig.5 and 40-.

Connected to the power input plug of the motherboard, a Step Up module was placed to go from 12 Volts to the 18.5 Volts that the main board works. An electronic circuit was made to power the side LEDs -fig.1-.

In this way, the TV works from 8 Volts to 30 Volts input, keeping its output stabilized at 18.5 Volts. An 11 Volt 4 Amp laptop battery pack was mounted on the frame or chassis. Observing that the television backlit by sunlight worked with a good image for more than 230 minutes without being connected to another power supply other than said battery. (With sound at the minimum audible).

When ambient light is high at the back of the TV the sidelight LEDs turn off, at which point the display's backlight is supplied by light passing through the figure 8 sheet. a window or skylight of the enclosure. -fig.39- With this natural lighting, an image with greater color richness is obtained, provided by the wide range of natural sunlight.

When the backlighting is Quantum Solar, the consumption associated with the television image drops to less than 1 Amper powered by 12 Volts, less than 12 Watts. Energy saving is especially important in areas where the electricity distribution network is not available. When electricity is generated with systems such as solar panels, where it is important to lower the consumption of devices. In this case, this television could be in service for a large part of the day with a very low power consumption. The savings are more noticeable with large screens. A test was also carried out with a 65-inch screen with a normal consumption of 170 Watts and with this Solar ecological backlighting system, excellent Image Colors were obtained with a consumption of 15 Watts. Although no in-depth studies were carried out on this matter, in practice it was noted that Vision with Solar Backlighting was less Aggressive compared to that of fluorescent tubes and LEDs, due to the absence of flickering and less classic Blue Light in LED illuminators. In addition to that the color spectrum in sunlight is more uniform in the width of the color spectrum. See figure 29.

A light projection or illuminator device was also designed that has a Rectangular panel -fig.9- optically connected to a triangle -fig.11, 12- made of solid light-conducting material. The rectangle contains mirrors -fig.10- that form a surface placed at an appropriate angle that reflects the light -fig.39- received at one vertex of the triangle, -fig.13- to the back of the image panel -fig. .7- This device has an Optical connector, which receives the light by means of a fiber optic conductor -fig.25, 13, which comes from a solar light concentrator formed by circular, transparent solid cylinders that conduct the sunlight, these on its upper face it has a slit in the shape of an inverted cone. This conical upper surface has a polarized paint or film that produces a downward mirrored surface on its lower face. Translucent from the upper face to the lower by 80%. In the lower side angle of this cone and axis of the cylinder comes out the optical conductor, which powers the screen illuminator device. Light can enter the cylinder at the top surface of the cone and be concentrated at the apex and exit through the optical conductor. Light can also enter through the walls of the circumference and be reflected towards the center of the cone through the lower mirrored side, concentrating at the vertex and exiting through the optical conductor -fig.25- to power the screen illuminator device. -fig.9-

For screens to be used on sidewalks or in open spaces, a device was made that consists of an elongated, solid, transparent and light-conducting cylinder arranged horizontally -fig.26- in its lower part it was joined to a plate of 6 mm acrylic -fig.7- that has a glued sheet -fig.8- permeable to bright light on the acrylic side and matte on the side that receives direct sunlight. -fig.39-. In the upper part of the cylinder, a mirrored polarized sheet -fig.28- was glued from the lower side, 80% translucent from the upper side towards the cylinder.

In the lower part of the cylinder, on the sides of the output of the acrylic plate -fig.7-, two sheets -fig.27- mirrored from the cylinder side were glued. Sunlight enters the cylinder through the surfaces without mirrored sheets, they are reflected illuminating the acrylic -fig.7- that retro-illuminates the image panel. In addition, when the sun is high at noon, the light -fig.39- enters through the upper sheet -fig.28- and reflects and illuminates the acrylic plate. -fig.7-.

Also Sunlight can directly hit the figure 8 sheet and go through the acrylic back plate illuminating the LCD.

The prototype was finished and was placed in a laboratory window from July 2019 to October 2020. At that time it was observed that the changes in luminosity of the days of each season did not affect acceptable vision. In the short days of winter, even with rainy or snowy days, you could see videos with low brightness but without making it impossible to see a playback. Of course sunny days could be seen with greater brightness and richness of colors. On sunny days but in which it is alternated with passing clouds that lower the brightness suddenly and for a few minutes, it was interesting to see that although the brightness of the image lowered, the brightness of an area with windows also logically lowered. At night, he also carried out the backlighting test with a common 15 Watt Led lamp light source projected about 20 cm behind the panel. And also in another test, said Focus was projected onto a white curtain of a window, achieving less brightness but an acceptable image without using the side LEDs.

Note: backlighting tests were performed on a small LCD panel of an Epson video projector. Managing to project images of good color quality but with low brightness. The need to develop a solar light collector that has an automatic mechanism for tracking the movement of the sun and fiber optics with greater driving performance was observed.
