Definitions
- the invention relates to the field of display screens and more specifically relates to a glass substrate with low infrared transmission intended to form the front face of emissive type screens.
- the invention will be more particularly described with regard to substrates used to display an image from a screen of the emissive type such as a plasma screen.
- a plasma screen generally consists of two glass sheets, more commonly known as “substrates”, separated by a space in which is imprisoned a mixture of plasma gas (Ne, Xe, Ar).
- the inner face of the back substrate is provided with phosphors which are excited by the ultraviolet radiation emitted by the plasma gas mixture during the plasma discharge between the two substrates and produce a visible light radiation (red, green, blue). The image produced from this radiation is projected through the substrate forming the front face of the screen.
- the emission of light is also accompanied by infrared radiation between 800 and 1250 nm which passes through the substrate before the screen.
- this radiation is likely to disturb to varying degrees the operation of neighboring devices when they are controlled by infrared, for example by means of remotes.
- plasma screens have addressing systems ("drivers") that generate electromagnetic waves that may interfere with devices such as microcomputers, mobile phones, etc.
- One known type of structure consists of two sheets of a plastics material, usually polyvinylbutyral (PVB), between which is arranged a network of metal wires in the form of a homogeneous grid.
- the grid consists of a fabric of metal wires bonded by heating between the PVB sheets, or etched directly onto a transparent substrate - glass or polyethylene terephthalate (PET) - by the usual photolithography technique, and said substrate being then assembled to the PVB sheets.
- PET polyethylene terephthalate
- the structure applied against the substrate is either kept away from the screen by peripheral fastening means, or glued directly to the glass by means of an adhesive.
- FR-A-2 843 273 it is proposed an improvement of this type of structure which consists of incorporating a mineral pigment or an inorganic dye in at least one of the sheets of thermoplastic material to reduce the transmission of infrared rays.
- Another improvement of the aforementioned structure uses the infrared reflection properties of metal conductors, especially silver.
- the improvement consists in depositing directly on the glass of the substrate before a transparent stack of thin layers comprising at least one layer based on silver.
- Such stacks are described in particular in FR-A-2 859 721, WO 01/81262, FR-A-2 868 961 and EP-A-1 155 816.
- the front substrate is generally made of toughened glass; most often, its outer face, which in the final disposition is opposite the viewer, is further coated with an anti-reflective layer advantageously resistant to scratching.
- the object of the invention is to propose a glass composition making it possible to produce a substrate for an emissive screen with low infra-red transmission capable of providing an acceptable transmitted image, in particular with high luminance, with high contrast and without altering the purity of the colors.
- the object of the invention is also to provide glass compositions which make it possible to produce a substrate by floating the molten glass on a bath of molten metal according to the "float" process under conditions similar to those of a silico-sodo glass. -calcic classic.
- a glass composition intended for the manufacture of a display screen substrate, in particular an emissive screen, having an infra-red transmission factor measured at 910 nm (T
- the glass composition according to the invention has a redox expressed by the ratio of the ferrous iron content FeO to the total iron content expressed as Fe 2 O 3 which varies from 0.15 to 0.40, advantageously from 0.20 to 0.35.
- the glass composition according to the invention has a dominant wavelength which varies from 485 to 520 nm.
- the glass composition according to the invention has a purity of less than 5, and advantageously less than 3%.

- the glass matrix comprises:
- SiO 2 57 - 75% preferably greater than 68%
- AI 2 O 3 O - 7% preferably 1 - 6%
- Li 2 OO - 1% preferably less than 0.5%
- the glass composition comprises, as coloring agents, the combination of the following compounds in the following proportions expressed in weight percentage:
- the redox ranges from 0.25 to 0.35.
- compositions containing only Fe 2 O 3 and FeO as coloring agents make it possible to obtain a glass having a high overall TL 06S light transmission factor, most often greater than 60%.
- the glass compositions comprise, as dyestuffs, the combination of the following compounds in the following proportions expressed in weight percentage: Fe 2 O 3 (total iron) 0.4 - 1.8 %
- NiO 0 - 1000 ⁇ m preferably 10O - 1000 ppm
- the redox varies from 0.20 to 0.30.
- This composition makes it possible to obtain a glass which can be melted under good conditions, in particular in a flame oven, because the amount of ferrous iron is low, which makes it possible to have a good transmission of the radiation emitted by the flames. in the glass bath and therefore an efficient heat transfer.
- the compositions which contain as Fe 2 O 3 , FeO and CuO dyes lead to glasses having a high overall transmittance TL D 65, similar to the glasses of the previous embodiment.
- NiO in the composition contributes to a better adjustment of the purity of the glass by maintaining a good level of overall light transmission under illuminant D65.
- the glass compositions according to the invention have the particular advantage of being able to be melted and converted into glass ribbon in the typical conditions of the float process, at temperatures similar to those applied for the production of traditional silico-soda-lime glass.
- SiO 2 plays an essential role.
- the content must not exceed 75% because beyond the melting of the vitrifiable mixture requires a high temperature and furthermore the coefficient of thermal expansion becomes too low. Below 53%, the stability of the glass and also the lower annealing temperature are insufficient.
- AI 2 O 3 acts as a stabilizer. It makes it possible to increase the lower annealing temperature of the glass, and to improve the chemical resistance, especially in a basic medium.
- the percentage of Al 2 O 3 advantageously does not exceed 10%, preferably 7% and better still 6% to avoid an increase in viscosity in unacceptable proportions at high temperatures and also a too large decrease in the coefficient of expansion.
- ZrO 2 also plays a stabilizing role. It improves the chemical resistance of the glass and helps to increase the lower annealing temperature. Above 8%, the risk of devitrification increases and the coefficient of thermal expansion decreases. Although this oxide is difficult to melt, it is advantageous because it does not increase the viscosity of the glass at high temperatures in the same proportions as SiO 2 and Al 2 O 3 .
- the melting of the glasses according to the invention remains within acceptable limits as long as the sum of the oxides SiO 2 , Al 2 O 3 and ZrO 2 remains equal to or less than 75%.
- acceptable limits it is meant that the temperature of the glass corresponding to a viscosity ⁇ of 100 poises does not exceed 1550 ° C. and preferably 1510 ° C.
- Na 2 O and K 2 O make it possible to maintain the melting temperature and the viscosity at high temperatures within the limits given above. They also control the coefficient of thermal expansion.
- the total content of Na 2 O and K 2 O is generally at least 8%, preferably at least 10%. Above 15%, the lower annealing temperature becomes too low.
- the K 2 O / Na 2 O weight ratio is at least 1, preferably at least 1, 2. It is also possible to incorporate Li 2 O in the glass composition as a flux in a content of up to 2%, preferably not more than 1% and preferably 0.5%. As a rule, the composition does not include Li 2 O.
- the alkaline earth oxides CaO, MgO, SrO and BaO have the effect of reducing the melting temperature and the viscosity of the glass at high temperatures. They also allow raising overall lower annealing temperature. The total content of these oxides is generally at least 15%. Beyond 25%, the risk of devitrification becomes incompatible with the conditions of the float process.
- the BaO content generally less than 12%, is preferably less than 9%, and more preferably less than 5% to limit the formation of BaSO 4 barium sulfate crystals which impair the optical quality of the glass.
- the BaO content in the glass corresponds to the unavoidable impurities of the raw materials.
- SrO helps to raise the lower annealing temperature and increases the chemical resistance of the glass. Its content is preferably less than 9%.
- the glass composition according to the invention is capable of being melted and converted into a glass ribbon by floating the glass on a bath of molten metal under the conditions of the "float" process for conventional soda-lime glass compositions.
- the glass ribbon is then cut to the appropriate dimensions to form viewing screen substrates, particularly on the front face.
- viewing screen substrates particularly on the front face.
- the glass matrix consists of the following constituents, in percentage by weight:
- the molten glass is deposited on a carbon table and formed into a plate.
- the plate is annealed in an oven at 655 ° C for 60 minutes.
- the sheet is cut into samples of 50 x 50 x 2.8 mm which are then polished.
- Redox defined as the ratio of the mass content of ferrous iron (expressed as FeO) to the mass content of total iron (expressed as Fe 2 O 3 ).
- R9 i 0 ), the light transmission (TL D 65), the dominant wavelength ( ⁇ o) and the purity (PD6S) are performed by taking the reference observer CIE 1931 (International Commission on Illumination of 1931).
- CIE 1931 International Commission on Illumination of 1931.
- redox the total iron content (Fe 2 O 3 ) is measured by X-ray fluorescence and the ferrous iron content (FeO) is measured by wet chemistry.

- CoO, NiO and / or Se (Examples 1 to 1 1) have the advantage of having a particularly advantageous neutral gray color.
- Examples 6 and 8 to 11 which associate CoO with NiO and / or Se make it possible to reduce the purity of the glass and thus to have a more neutral color compared to Examples 2, 1 and 3 to 5 respectively, and this keeping a comparable factor T 9 -I 0 .
- Example 7 which contains a higher amount of selenium than Example 8 makes it possible to obtain a glass of purity similar to that of Example 1 with a higher dominant wavelength.
- compositions of Examples 12 to 19 which combine Fe 2 O 3 , FeO and CuO, optionally NiO, have a relatively neutral gray color.
- compositions can be melted under particularly favorable thermal conditions.
