Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
62 words
A LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE LACQUER CONSISTING ESSENTIALLY OF A SUBSTANTIALLY TRANSPARENT ORGANIC PLASTIC HAVING UNIFORMLY DISPERSED THEREIN LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE PARTICLES OF INDIUM OXIDE THE ELECTRICAL CONDUCTIVITY OF WHICH IS SUBSTANTIALLY INSENSITIVE TO INCIDENT LIGHT RADIATION, SAID CONDUCTIVE INDIUM OXIDE PARTICLES BEING PRESENT IN SAID LACQUER HAVING A LIGHT TRANSMITTANCE OF AT LEAST 60% AT A FILM THICKNESS OF APPROXIMATELY 15 MICRONS.
Claim 2
Dependent Claim
62 words
A LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE LACQUER CONSISTING ESSENTIALLY OF A SUBSTANTIALLY TRANSPARENT ORGANIC PLASTIC HAVING UNIFORMLY DISPERSED THEREIN LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE PARTICLES OF INDIUM OXIDE THE ELECTRICAL CONDUCTIVITY OF WHICH IS SUBSTANTIALLY INSENSITIVE TO INCIDENT LIGHT RADIATION, SAID CONDUCTIVE INDIUM OXIDE PARTICLES BEING PRESENT IN SAID LACQUER HAVING A LIGHT TRANSMITTANCE OF AT LEAST 60% AT A FILM THICKNESS OF APPROXIMATELY 15 MICRONS.
Claim 3
Dependent Claim
104 words
AN ELECTROLUMINESCENT DEVICE COMPRISING A LAYER OF ELECTROLUMINESCENT PHOSPHOR SANDWICHED BETWEEN A PAIR OF ELECTRODE LAYERS, ONE OF SAID ELECTRODE LAYERS BEING LIGHT-TRANSMISSIVE AND BEING CONSTITUTED SOLELY BY A FILM OF A LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE LACQUER CONSISTING ESSENTIALLY OF A SUBSTANTIALLY TRANSPARENT ORGANIC PLASTIC HAVING UNIFORMLY DISPERSED THEREIN LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE PARTICLES OF INDIUM OXIDE THE ELECTRICAL CONDUCTIVITY OF WHICH IS SUBSTANTIALLY INSENSITIVE TO INCIDENT LIGHT RADIATION, SAID CONDUCTIVE INDIUM OXIDE PARTICLES BEING PRESENT IN SAID LACQUER IN AN AMOUNT OF AT LEAST 10% BY VOLUME AND SAID LACQUER HAVING A LIGHTTRANSMITTANCE OF AT LEAST 60% AT A FILM THICKNESS OF APPROXIMATELY 15 MICRONS.
Claim 4
Dependent Claim
104 words
AN ELECTROLUMINESCENT DEVICE COMPRISING A LAYER OF ELECTROLUMINESCENT PHOSPHOR SANDWICHED BETWEEN A PAIR OF ELECTRODE LAYERS, ONE OF SAID ELECTRODE LAYERS BEING LIGHT-TRANSMISSIVE AND BEING CONSTITUTED SOLELY BY A FILM OF A LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE LACQUER CONSISTING ESSENTIALLY OF A SUBSTANTIALLY TRANSPARENT ORGANIC PLASTIC HAVING UNIFORMLY DISPERSED THEREIN LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE PARTICLES OF INDIUM OXIDE THE ELECTRICAL CONDUCTIVITY OF WHICH IS SUBSTANTIALLY INSENSITIVE TO INCIDENT LIGHT RADIATION, SAID CONDUCTIVE INDIUM OXIDE PARTICLES BEING PRESENT IN SAID LACQUER IN AN AMOUNT OF AT LEAST 10% BY VOLUME AND SAID LACQUER HAVING A LIGHTTRANSMITTANCE OF AT LEAST 60% AT A FILM THICKNESS OF APPROXIMATELY 15 MICRONS.
