  • 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.
  • 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.
  • the degree to which illumination can be adjusted and colour varied is limited. Accordingly, it is not possible to use the illuminating device for decoration purposes.

  • filters are mounted to the upper dampproofing layer, disposed between the UV coating layer and the transparent electrode plate, to realize the display of a variety of colours.
  • 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 % IN 2 O 3 , 42% SnO 2 , and 3% hardening agent at the thickness of 1000 ⁇ ; 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 UV coating layer, and a front surface member on the transparent 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 (CU 2 SO 4 ) solvent on an aluminium 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.
  • CU 2 SO 4 copper sulfide

  • 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 the middle electrode plate 8.
  • the middle and lower electrode plates 8 and 88 are made by depositing a copper sulfide (CU 2 SO 4 ) solvent on an aluminium 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.
  • CU 2 SO 4 copper sulfide
  • 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 - 600°C. As a result, the luminous phosphor layer 9 is formed between the transparent electrode plate 7 and the middle electrode plate 8.
  • the transparent electrode plate 7 is made from a mixture of 55% IN 2 O 3 , 42% SnO 2 , and 3% hardening agent which is sprayed then hardened at a thickness of 1000 ⁇ such that electrical resistance is minimized.

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 UV coating layer 2a to be radiated out the front surface member 2.
  • 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 colours 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.

If the size of the luminous dust particles is set at 0.5-1 ⁇ 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.
