Abstract:
A wavelength converting structure is provided. The wavelength converting structure comprises the following:a substrate, anda wavelength converting coating which is deposited on the substrate and comprises:(a) a phosphor powder which can be excited by UVC; and (b) an anti-UVC adhesive, wherein the thickness of the wavelength converting coating is 2 to 10 times the average particle size of the phosphor powder and the amount of the phosphor powder in the wavelength converting coating conforms to at least one of the following requirements:(i) the phosphor powder should be about 30% to 85% by volume of the wavelength converting coating based on the total volume of the phosphor powder and the adhesive; and(ii) the weight ratio of the phosphor powder to the adhesive should range from 1:1 to 20:1.The wavelength converting coating can effectively convert UVC to visible light to provide a visible light source with a high surface area.
Abstract:
A first light-transmitting substrate having a first light-transmitting electrode layer and a second substrate having at least a second electrode layer are attached to each other with a resin which is cured by UV light or the like, to form an inorganic EL light-emitting element. Thus, a display device is manufactured. The light-emitting layer may be interposed between the first light-transmitting substrate having the first electrode layer and the second substrate having the second electrode layer, and may be formed either on the first electrode layer side or on the second electrode layer side.
