Definitions
- the invention relates to transparent substrates, particularly glass substrates, which are provided with an anti-reflective coating with abrasion resistance properties. It also relates to their use as glazing or filters for display screens, for example plasma screens.
- an anti-reflective coating has the function of reducing its light reflection, therefore increasing its light transmission.
- a substrate thus coated therefore sees an increase in its transmitted light / reflected light ratio, which improves the visibility of the objects placed behind it.
- an anti-reflective coating can be measured or evaluated according to different criteria.
- criteria First, of course, are the optical criteria. It can be considered that a “good” anti-reflection coating must be able to lower the light reflection of a standard clear glass substrate up to a given value, for example 2%, or even 1% and less.
- Coating by stacking layers is often used for glazing in the building and automotive industries. These are thin interference layers deposited on the substrate, in general an alternation of layers with high and low refractive indices.
- an anti-reflection coating by stacking of layers which meets the criterion of good optical quality and which also has the advantage of keeping this quality in a wider range of angles of incidence oblique to the vertical, which can range from 50 to 70 ° inclination.
- This type of coating is particularly appreciated for glazing of the windshield type, store counters.
- Another anti-reflective coating is known as an anti-reflective plastic film which, on the other hand, is used for display screens of all types, and for example plasma screens. Such a film is generally associated with a transparent window which serves as a filter for the display screen.
- a plasma screen comprises a plasma gas trapped between two sheets of glass, and phosphors arranged on the internal face of the back sheet of the screen.
- the interactions between the particles of the plasma gas and the phosphors generate a radiation of electromagnetic waves which are located in the near infrared between 800 and 1000 nm and whose propagation, mainly through the face front of the screen, can be the source of very annoying disturbances, in particular for equipment located nearby and controlled by infrared, for example by means of remote controls.
- plasma screens have addressing systems (drivers) which can generate parasitic radiation vis-à-vis other devices with which they must not interfere such as microcomputers, mobile phones. ..
- this shielding can comprise one or more metallic layers, in particular silver, and / or one or more metallic grids.
- This shielding can advantageously be ensured by a stack of at least two metallic silver layers which are either directly deposited on the glass substrate constituting the window and facing the screen, or deposited on an adhesive film bonded to the substrate. next to the screen.
- this adhesive film has an anti-reflection function (vis-à-vis the light radiation coming from the screen) to improve the brightness of the screen by reducing the light reflection.
- the window substrate can be tempered glass or non-tempered glass.
- an adhesive film capable of retaining the pieces of glass in the event of breakage and fragmentation of the tempered glass. and also carrying an anti-reflection function for the comfort of the spectator. The film is placed last on the substrate because it could not withstand the various treatments that the substrate can undergo with a view to depositing functional elements, such as the stacking of metal layers.
- the film being placed on the external face of the protective window which is intended to be associated with a display screen, the repeated actions of cleaning the protective window end up damaging this anti-reflective film, which generates loss of anti-reflection properties and blurring of vision, the film then having to be replaced.
- the object of the invention is to provide a substrate, intended in particular for filters for display screens, which comprises on one side at least one functional element and on its opposite side an anti-reflective coating, being ensured that the substrate does not has no scratches type defects at the end of its manufacturing process and that the anti-reflective coating is durable and resistant to abrasion.
- the substrate in particular glass, comprising on one side at least one functional element of the metallic element type, and on the opposite side an anti-reflection coating, is characterized in that the substrate comprises an anti-scratch coating and resistant to abrasion, said coating consisting of the antireflection coating made of a stack of thin layers of dielectric material with alternately strong and weak refractive indices.
- the invention also relates to a transparent substrate, in particular a glass substrate, comprising on at least one face an anti-reflection coating, characterized in that the substrate comprises an anti-scratch coating with a resistance of at least 3 hours and with a resistance to abrasion such as blurring of the substrate which may to be generated remains less than 1.5%, said coating consisting of the anti-reflection coating made of a stack of thin layers of dielectric material with alternately strong and weak refractive indices.
- the antireflection coating by stacking of layers is deposited on the substrate before the deposition of the functional element.
- the substrate coated first with the stack of antireflection layers effectively exhibits its antireflection function as desired, and makes it possible to treat the substrate to deposit on one of the faces of the functional elements without risking damaging the opposite face because the latter is already coated with an anti-scratch layer constituted by the stack of anti-reflective layers.
- the stack is based on layers of Si 3 N or Sn0 2 and of Si0 2 . It has indeed been found that this type of combination of layers is particularly resistant to abrasion and for relatively large surfaces, that is to say well beyond 10 cm 2 .
- the stack comprises:
- a first layer (d) with high index, of refractive index neither between 1, 8 and 2.2 and of a geometric thickness ei between 5 and 50 nm, * ⁇ - a second layer (c2), at low index, of refractive index n 2 between 1.35 and 1.65 and of geometric thickness e 2 between 5 and 50 nm, * ⁇ - a third layer (c3), at high index, of refractive index n 3 between 1, 8 and 2.2 and of geometric thickness e 3 between 70 and 120 nm, * -> a fourth layer (c4), at low index, of index of refraction n 4 between 1.35 and 1.65 and of geometric thickness e 4 of at least 80 nm.
- the invention also relates to a glazing or filter, characterized in that it is composed of the only substrate provided on one of its faces with the stack of anti-reflective layer and on its other face of the element functional consisting of a metal element for shielding electromagnetic.
- the application is particularly intended for the manufacture of filters for display screens such as plasma screens.
- the metallic element consists, for example, of at least one conductive metallic layer, and rather of a stack of thin layers comprising at least two silver layers.
- the conductive metal layer is based on silver and is part of a stack of layers having the following sequence, Si3N 4 / ZnO / Ag / Ti / Si3N 4 / ZnO / Ag / Ti / ZnO / Si3N4.
- the functional element may consist of a network of metallic wires in the form of a grid, or alternatively of a combination of a stack of thin layers based on silver and a network of metallic wires. in the form of a grid.
- the functional element may be deposited on the substrate or on a plastic film made integral with the substrate, or else be laminated between two plastic films, one of which is made integral with the substrate while the other is made integral with a other substrate.
- the functional element is preferably associated with an antireflection coating which can be either a stack of antireflection layers or an adhesive antireflection film.
- non-tempered glass substrate for the application of display screens, because the substrate equipped with one or more functional elements and with the stack of anti-reflective layers can thus be produced on large surfaces and easily cut to size. dimensions of filters for display screen without risk of breakage of the fully equipped substrate.
- FIG. 1 is a schematic sectional drawing of a filter according to the invention associated with a plasma screen
- FIG. 2 illustrates a comparative graph of different anti-reflective coatings
- FIG. 3 shows two images of a coating respectively, of the film type and of the layer stacking type
- FIG. 4 shows a sectional view of a variant filter according to the invention associated with a plasma screen.
- FIG. 1 illustrates a transparent window 1 intended to be assembled on the front face of a plasma screen E.
- This window constitutes an electromagnetic shielding protection and anti-reflection protection filter.
- the transparent window 1 consists of a single substrate, such as a glass sheet 10, on which is deposited on the one hand against the internal face, facing the screen, a first functional element 20 consisting of a stack of metal layers with electromagnetic shielding properties and a second functional element 21 constituted by an internal anti-reflection coating covering the stack of layers 20, and on the other hand against the external face, opposite the screen and facing d 'A possible spectator, a stack of anti-reflective layers 11 which constitutes not only an anti-reflective coating but also an anti-scratch and abrasion resistant coating.
- the substrate 10 is made of clear soda-lime-silica glass of the Planilux type 3 to 6 mm thick, for example 4 mm. This product is marketed by SAINT-GOBAIN GLASS.
- the stack of metal layers 20 is constituted, for example, by at least two electrically conductive functional layers, of the Ag type. These metal layers are inserted in a stack of thin protective layers, the preferred sequence of which is as follows:
- the Ti layer constitutes a metallic protective layer against silver, in particular preventing the oxidation of silver.
- a layer of TiO 2 can be interposed between the layers of Si 3 N 4 and ZnO close to the glass so as to "wash" the color in reflection of the substrate.
- the layers of the stack are deposited by a known sputtering technique on the internal face of the substrate intended to be opposite the screen.
- the layers are in any case directly deposited on the glass substrate and not on a plastic film as it is sometimes produced in the prior art because as we will see by the results of Example 3 below, a support film of these metallic layers create more blur.
- the first metallic layer of Ag placed closest to the substrate has a thickness ei substantially equivalent to the thickness e 2 of the
- the thickness ratio - is e 2 between 0.8 and 1.1, and preferably between 0.9 and 1.
- the total thickness e ⁇ + e 2 of the metal layers is between 27 and 30 nm.
- a total thickness of the metal layers will preferably be chosen between 28 and 29.5 nm, the radiation transmission thus reaching no more than 13% for a wavelength of 800 nm.
- metallic elements for electromagnetic shielding can be envisaged, such as metallic grids or a combination of grids and layers.
- the functional element 20 of electromagnetic shielding is deposited directly on the glass but can alternatively be deposited on an adhesive plastic film made integral with the internal face of the window, or else be laminated between two plastic inserts I made integral by adhesion of two substrates such as the substrate 10 and a glass substrate 10a facing the screen, the substrate 10 being provided with the internal coating 21 (FIG. 4).
- the internal anti-reflective coating 21 covering the stack of layers 20 can, according to a first embodiment, be a conventional anti-reflective plastic film 21a or a stack of layers 21b of the stack 11 type.
- the stack of layers 21 b of type 11 makes it possible, with respect to the film, which can be fragile, to protect very well from corrosion the silver layers of the stack 20 due to the covering with silica and nitride of silicon.
- the advantage of a film for the functional element 21, except that in the event of breakage of the window all the shards of glass are maintained by this one, is that one can act on the contrast of the 'screen.
- we can take a film of 80% light transmission marketed by the company CALSAK or lower transmission to improve the contrast of the screen such as a film of 70% light transmission marketed by the company SOUTHWALL (product referenced ARA2-70).
- the stack of anti-reflective layers 11 is a stack of at least two layers based on Si 3 N 4 or Sn0 2 and Si0 2 which are particularly suitable for their hardness property. These layers have all been deposited in a conventional manner by sputtering assisted by magnetic field and reactive, in an oxidizing atmosphere from target of Si or metal to make layers of SiO2 or metal oxide, from target of Si or of metal in a nitriding atmosphere to make nitrides, and in a mixed oxidizing / nitriding atmosphere to make oxynitrides.
- Si targets can contain another metal in small quantities, in particular Zr, Al, in particular in order to make them more conductive.
- a preferred anti-reflective stack is as follows:
- the purpose of this example is to minimize as much as possible the value of the light reflection RL of the glass (on the spectator side) at 60 ° incidence.
- the table below summarizes the results in light reflection from the viewer side and in optical blur of the screen-filter product according to the example of the invention (example 1) and according to two examples of comparative configuration (examples 2 and 3).
- the filters both have, as a functional element 21 and anti-reflection coating 11, anti-reflection films on either side of the substrate, but the stack 20 of layers of Ag is for one directly deposited on glass (example 2), and for the other on a plastic film (example 3).
- Example 1 adhesive anti-reflective film 21a / stacking of layers Ag / Glass / stacking of layers 11;
- Example 2 adhesive anti-reflective film / stacking of Ag / Glass layers / adhesive anti-reflective film;
- Example 3 Adhesive anti-reflective film / stacking of Ag layers on plastic film / Glass / adhesive anti-reflective film.
- Example 1 of the invention is indeed that to be retained because the anti-reflective coating 11 by stacking of layers has the advantage of reducing the light reflection on the external face of the window, on the spectator side, while producing a less blurred product. at the end of manufacturing.
- the reduction in blur (diffuse light) improves the quality of the image and the quality of vision of the spectator, the colors are notably more vivid.
- the stack of anti-reflective layers also constitutes an anti-scratch and abrasion-resistant coating.
- the graph in FIG. 2 shows that the window of the invention has an abrasion behavior according to the taber test much better than the window of the state of the art.
- the coating with a stack of layers is practically not scratched, while the coating with the plastic film is completely torn off, which causes a complete loss of the anti-reflective properties and generates significant blurring.
- the micrographs of Figure 3 with a magnification of 80 times show the appearance of the two products after testing; the window with stacked layers is much sharper.
- the measurements made concerning the scratch resistance shows that the resistance with stacking of layers is much higher than that with film. It is only 2 to 3 hours for the film while it is more than 3 hours for the stacking of layers.
- H is the classification used in the field of surface coatings and organic substrates; it is a scratch test using a pencil hardness of 2 or 3H.
- the window associated with a plasma screen was taken by way of example but the invention obviously applies to any type of substrate which must optionally have on one side at least one functional element and on its opposite side an anti- scratches and resistant to abrasion and which optionally has the advantage of constituting an antireflection.
