Abstract:
An apparatus for exposing a photosensitive material, said photosensitive material ha ng a light receiving surface and being exposed by radiation impinging on said light receiving surface, said apparatus comprising:a substrate having a substantially planar first surface oppositely spaced apart from a substantially planar second surface; and an individually addressable Organic Light Emitting Diode (OLED) structure, said structure comprising at least one of a plurality of triplets of elongated arrays of individually addressable Organic Light Emitting Diode (OLED) elements, said Organic Light Emitting Diode (OLED) structure being deposited onto the first surface of said substrate; and wherein said OLED elements emit light over a broad range of wavelengths, any said LED element in said at least one of a plurality of triplets of said elongated arrays has a characteristic surface dimension which is substantially the same for all OLED elements in the array and from which an OLED center point can be defined; and relation to said color filter arrays, said light receiving surface oppositely spaced apart from a light emitting surface and; wherein each OLED array in the triplet is in effective light transmission relation to the light receiving surface of one color filter array in the triplet thereby constituting an OLED color filter array set, each set in the triplet being a aligned in substantially parallel spaced relation with respect to each other set in the triplet, each color filter array in each triplet having elements that are capable of transmitting radiation in a distinct wavelength range different from the distinct wavelength range of the other two arrays in the triplet, each triplet being aligned in substantially parallel spaced relation with respect to any other triplet.
