Abstract:
PURPOSE: A programmable mask and a method for fabricating a biomolecule array using the same are provided. A high density biomolecule array is fabricated by selectively irradiating UV to sample substrate. CONSTITUTION: A programmable mask comprises a lower substrate(100a) comprising a polysilicone thin layer transistor, a lower pixel electrode(117) consisting of transparent electrode connected to drain electrode(112) of the thin layer transistor and an orientation film(116) in the upper part, and a polarizing plate(120a) in the lower part; an upper substrate(100b) comprising a UV shade, a protection and insulation film, an upper pixel electrode(119) consisting of transparent electrode and an orientation film(116) in the lower part, and a polarizing plate(120b) in the upper part; liquid crystal being inserted between the upper and lower substrates and selectively transmitting light according to electric signal; and an operating circuit on the lower substrate, wherein the operating circuit is formed with the polysilicone thin layer transistor simultaneously and positioned in the same plane as the pixel region.
Abstract:
PURPOSE: A blue ELD(electroluminescent display) is provided to ensure low operating voltage, high efficiency and easy adjustment of luminance by using a uniform thin fluorescent film of Cas:Pb grown through atomic layer deposition or chemical deposition. CONSTITUTION: A DC blue ELD has a transparent glass substrate(1), a transparent electrode(2) on the transparent glass substrate(1), a CaS:Pb fluorescent film(3) on the transparent electrode(2), an insertion thin film(4) on the fluorescent film(3) and a metal electrode(6) on the insertion thin film(4). The CaS:Pb fluorescent film(3) has a thickness of 1000 to 10000 angstroms, and is doped with phosphor Pb 0.4 to 2.0mol%. A current barrier film is formed between the insertion thin film and the metal electrode, and made of a MnO2 layer.
