Description
CA 022114~2 1997-08-19 LUMINOUS DISPLAY AND A MANUFACTURING METHOD THEREOF
Fiel~ of the Tnv~nt;o~
The present invention relates to a luminous display, and more particularly, to a luminous display which is used for decoration by being installed on an interior or exterior wall of a building and a manufacturing method thereof.
B~ckgrolln~ of th~ Tnv~nt; ~n Generally, luminous displays utilizing electrodes connected to a luminous phosphor layer to radiate light are used in a variety of electronic and electric goods. The displays show information for the user to view. An example is the display used in public telephones which indicates the amount of money inserted in the phone and the amount remaining. Such luminous displays enable users to view the display at night or in dark places.
ln the above luminous displays, as an electrode plate made of In203 or Sn~ is used on both sides of the luminous paint layer, a large amount of electrical power is used because of the high level of electrical resistivity, manufacturing of the display with dimensions larger than lOcm X 3cm is difficult, and manufacturing of the devices is costly.
Further, in the conventional luminous display, as a result of the size limitation and the high resistance value of the electrode plates, the degree to which illumination can be adjusted and color varied is limited. Accordingly, it is not possible to use the illuminating device for decoration purposes.
Conventional luminous displays used for decoration include incandescent lights, fluorescent lights, and neon signs. However, CA 022114~2 1997-08-19 such devices are not energy efficient, are expensive to install, and generate an excessive amount of heat. As a result, it is not practical to the displays for decoration in the home.
S~ ry of ~hP Tnv~nt;on The present invention has been made in an effort to solve the above problems.
It is an object of the present invention to provide a luminous display used for decoration and a manufacturing method thereof which, though using a luminous phosphor layer, can be manufactured to large sizes, and is able to attain a high degree of illumination and allow the use of a variety of colors such that both commercial and home use is feasible.
To achieve the above object, the present invention provides a luminous display used for decoration including a front surface member and a rear surface member. There are included between the front and rear surface members, transparent, middle, and lower electrode plates provided between the front and rear surface members, a luminous phosphor layer disposed between the transparent and middle electrode plate, a W coating layer provided adjacent to the front surface member, an upper dampproofing layer disposed between the W coating layer and the transparent electrode plate, a lower dampproofing layer provided adjacent to the rear surface layer, an ionized layer provided between the lower and middle electrode plates, and a sealing frame placed around the luminous display, over the edges of the front and rear surface members and to seal all the layers therebetween.
CA 022114~2 1997-08-19 According to a feature of the present invention, filters are mounted to the upper dampproofing layer, disposed between the W
coating layer and the transparent electrode plate, to realize the display of a variety of colors.
A method for making a luminous display, comprising the steps of: disposing a lower electrode plate and a middle electrode plate on a lower dampproofing layer disposed on a rear surface member, an ionized layer being disposed between the electrode plates; spraying a mixture made of 67% cyano ethyl celluloid solution and 33% luminous dust on the lower surface of a transparent electrode plate which is made from a mixture of 55%
In2O3, 42% SnO2, and 3% hardening agent at the thickness of 1000 A; heat-treating the transparent electrode plate at 500~C - 600~C
to form a luminous phosphor layer between the transparent electrode plate and the middle delectrode plate; depositing a dampproofing layer, a W coating layer, and a front surface member on the transpatent electrode plate; and sealing the luminous display and all the layers using a frame placed around the edges of the luminous display.
The middle and lower electrode plates are made by depositing a copper sulfide (Cu2SO4) solvent on an aluminum plate, drying the same, then heat treating the plates between 380~C - 430~C
such that the lower and middle electrode plates have a high degree of electrical conductivity.
Further, the luminous dust includes 55% TiO2, 30% zinc oxide (ZnO), and 15% zinc sulfide (ZnSO4) and the particles of said luminous dust are sized at 0.5-l~m such that direct current is CA 022114~2 1997-08-19 used in the luminous display.
The luminous dust may be sized at 5-20~m such that alternating current is used in the luminous display.
Brief Descript;o~ of ~hP Dr~w;n~s The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention, and, together with the description, serve to explain the principles of the invention:
Fig. 1 is a perspective view of a luminous display according to a preferred embodiment of the present invention; and Fig. 2 is a partial sectional perspective view of the luminous display shown in Fig. 1.
Det~;le~ Descr;pt;o~ of th~ Preferre~ ~mho~;ment Reference will now be made in detail to the present preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings.
In the drawings, reference numeral 1 denotes a luminous display according to a preferred embodiment of the present invention. A transparent electrode plate 7, middle, and lower electrode plates 8, and 88 and a luminous phosphor layer 9 are provided between a front surface member 2 and a rear surface member 3 of the luminous display.
A dampproofing layer 5 is interposed between the rear surface member 3 and the lower electrode plate 88, and an ionized layer 6 is interposed between the lower electrode plate 88 and CA 022114~2 1997-08-19 the middle electrode plate 8. The middle and lower electrode plates 8 and 88 are made by depositing a copper sulfide (Cu2SO4) solvent on an aluminum plate, then after drying, heat treating the plates between 380~C - 430~C such that the lower and middle electrode plates 8 and 88 have a high degree of electrical conductivity.
A mixture made of 67% cyano ethyl celluloid solution and 33%
luminous dust is sprayed on a lower surface of the transparent electrode plate 7, then the same undergoes a heat-treatment process at 500~C - 60~ C. As a result, the luminous phosphor layer 9 is formed between the transparent electrode plate 7 and the middle electrode plate 8.
Further, the transparent electrode plate 7 is made from a mixture of 55% In2O3, 42% SnO2, and 3% hardening agent which is sprayed then hardened at a thickness of lOOOA such that electrical resistance is minimized.
A dampproofing layer 4 is provided on top of the transparent electrode plate 7, and a W coating layer 2a is provided on top of the dampproofing layer 4. The front surface member 2 is placed on top of the W coating layer 2a. A sealing frame 10 is placed around the luminous display 1 over the edges of the front and rear surface members 2 and 3 to seal all the layers therebetween.
Electrical power is supplied to the luminous display 1 by an electrical wire 11 and a plug 12 which are connected to the electrode plate 7, 8, and 88. With the supply of electrical power, light is emitted from the luminous phosphor layer 9 which passes through the transparent electrode plate 7, the dampproofing layer 4, and the W coating layer 2a to be radiated out the front surface member 2.
In the luminous display 1 structured as in the above, it is preferable to add a compound to allow different levels of illumination to be controlled and colors to be varied. Such an addition allows both direct and alternating current to be used, and the control of the level of illumination from 40Lit to 800Lit.
Namely, the luminous phosphor layer 9 is formed by spraying a compound comprised of 67% cyano ethyl celluloid solution and 33% luminous dust on the lower surface of the transparent electrode plate 7, then heat treating the compound at 500~C -600~C.
The above luminous dust includes 55% TiO2, 30% zinc oxide (ZnO), and 15~ zinc sulfide (ZnSO4). If the size of the luminous dust particles is set at 0.5-l~m and the particles amassed, direct current can be used in the luminous display 1. However, when the size of the dust particles is set at 5-20~m and the particles separated, alternating can be used in the luminous display 1.
When wanting to display colors from the luminous phosphor layer 9, copper (Cu), chrome (Cl), aluminum (Al), manganese (Mn) and other such elements are added at different ratios to zinc sulfide (ZnS). If 0.04% Cu and 0.005% Cl are added to ZnS a red color can be displayed, if 0.08% Cu and 0.02% Al are added to ZnS
a green color can be displayed, and adding 0.05% Cu and 1.3% Mn to ZnS allows a pink color to be displayed. It is also possible to realize the display of a variety of colors by mounting color filters to the dampproo~ing layer 4.
CA 022114~2 1997-08-19 With regard to illumination, if the ratio of Mn to Cu is fixed to 1.5/1, by maintaining maximal density ratio of Mn at 0.5mol%, and that of Cu at 0.3mol%, a degree of illumination of 2400cd/m2 can be attained. Here, it is preferable that a thickness of the luminous phosphor layer 9 is within a range of 5000-6000A with a ~3% deviation.
The transparent electrode plate 7 is formed on the luminous phosphor layer 9 from a mixture of 55% In2O3, 42% SnO2, and 3%
hardening agent at a thickness of lOOOA. Accordingly, the resistance value of the transparent electrode plate 7 is minimized to 10-SQ such that only a small amount of electricity is consumed.
Further, the middle and lower electrode plates 8 and 88 are made by depositing a copper sulfide (Cu2SO4) solvent on an aluminum plate, drying the solvent, and heat treating the plates between 380~C - 4~~O C. As a result, the lower and middle electrode plates 8 and 88 have a high degree of electrical conductivity, allowing the overall size of the luminous display 1 to be substantially enlarged without the lower and middle electrode plates 8 and 88 warping, while preventing the generation of a potential difference and a reduction in illumination.
In the above, by providing the dampproofing layer 4, the W
coating layer 2a, and the front surface member 2 on top of the transparent electrode plate 7, and the dampproofing layer 5 and the rear surface member 5 under the lower electrode plate 88, then placing the sealing frame 10 around the all the edges of the luminous display 1, interference from external light is prevented CA 022114~2 1997-08-19 by the W coating layer 2a such that the desired color can be displayed.
In the luminous display of the present invention structured as in the above, the electricity usage is kept to a minimum by utilizing only 0.5W - 5W per lm2. Also, the display allows both direct and alternating current of 6V - 220V to be used, the size of the display can be greatly increased and the shape altered in a variety of ways, and can realize an assortment of colors and levels of illumination enabling the display to be used for commercial purposes as well as in the home.
While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
