Abstract:
The electroluminescent system comprises an electroluminescent device (1) having a first, two-dimensional electrode (2) made of a transparent material. A layer (3,4) made of luminescent dielectric is assigned to each of the large surfaces of said first electrode (2). Said luminescent layers (3,4) are transparent and are made of materials that can emit light with different wavelengths. An electrode (5, 6) is assigned to each large surface of the luminescent layers (3, 4) opposite the common electrode (2). A support layer (7) which is also made of transparent material is located on the front side of said electroluminescent device (1). A voltage source (11, 12) is connected between two successive electrodes (5, 2, 6).
Abstract:
Disclosed is a liquid crystal display adopting a polarized light source and a phosphor filter. The liquid crystal display comprises a backlight unit which has at least one non-polar or semi-polar LED chip to emit polarized ultraviolet rays, and a phosphor filter for converting the wavelength of the ultraviolet rays, thereby reducing optical loss and the thickness of an LCD module.

Abstract:
The present invention is a method of selecting composite sheet materials for use in ultra-fast laser patterning of layers of organic thin film material such as OLEDs. The material is selected to accomplish patterning of upper layers without damaging underlying layers by using an ultra-fast laser programmed with the appropriate laser processing parameters. These parameters are derived by examining each layer's absorption spectra, thermal, and chemical characteristics. The method of the present invention includes measuring each layer's absorption spectrum, examining each layer's thermal and chemical characteristics, determining if the layer is ablatable, determining the laser setup, patterning the layer through laser ablation processing, and determining if more layers need to be ablated. Further, the method includes a sub-method of selecting an alternate material if a layer's material characteristics are not favorable for ablation without damaging underlying layers.
Abstract:
A display device (10) (Fig. 1) which can be a plasma display panel or a highly loaded fluorescent lamp, comprises a hollow, translucent glass body (12) containing a medium capable of generating at least several wavelengths of UV radiation. A plurality of phosphors is disposed on the inside surface of the glass body, the plurality of phosphors emitting visible radiation upon exposure to the UV radiation. At least one of the plurality of phosphors is subject to degradation upon long-term exposure to one of the at least one of several wavelengths of UV radiation that may be available. The at least one of the plurality of phosphors subject to degradation is installed (Fig. 2) adjacent the inside surface (14) of the glass body to form a first layer (16); and, the remainder of the plurality of phosphors is disposed on the first layer to form a second layer (18), the second layer not being subject to long-term degradation upon exposure to the UV radiation. In some embodiments (Fig. 3) a layer of alumina (20) may first be applied to the inside surface (14) of the glass and the first phosphor (22) applied over the alumina.
