To reuse glass used in a flat panel display, processing suitable for global environment such as processing of separating a lead component must be realized. A disassembly processing method for a flat panel display having a structure in which a face plate and rear plate mainly containing glass are airtightly joined via a frame with frit glass is characterized by including the step of separating the face plate and rear plate joined with the frit glass. The separation step is characterized by separating the face plate and rear plate by cutting, dissolution, or melting.

Glass substrate processing method and material removal process using x-ray fluorescence

A reaction curable resin is irradiated with ultraviolet light having wavelengths of 250 to 380 nm. A screen image of luminance value, which is obtained by extracting only a specific wavelength component of the reflected ultraviolet light, is recorded, and the cured state of an ultraviolet curable resin is quantified from a captured image and displayed. At the same time, the spectral characteristics of reflected light are measured by an ultraviolet spectroscope and a cured state is quantified in accordance with the change rate of absorbances obtained from a change of spectral characteristics by combining the spectral characteristic with a luminance value image and displayed.

Apparatus and method for measuring cured state of reaction curable resin

A display device includes a first substrate and a second substrate disposed opposite to each other, and a display medium including an insulating liquid and electrophoretic colored particles dispersed therein and disposed between the first and second substrates. A first electrode and a second electrode are provided for applying a voltage to the display medium so as to move the colored particles between the first and second electrodes to effect a display depending on a voltage applied to the first and second electrodes. The electrophoretic colored particles are distributed uniformly without localization by incorporating the display medium in a plurality of light-transmissive tubes, and disposing and fixing the plurality of tubes in intimate contact with each other between the first and second substrates.

Metal-containing composition for forming electron-emitting device

An electron-emitting device has a pair of device electrodes formed on a substrate, an electroconductive film connecting the device electrodes and an electron-emitting region formed in the electroconductive film. The electron-emitting device is manufactured by (1) applying an ink containing the material for producing the electroconductive film to a predetermined position of the substrate in the form of one or more than one drops by means an ink-jet apparatus, (2) drying and/or baking the applied drop(s) to turn the drop(s) into an electroconductive thin film and (3) applying a voltage to the pair of device electrodes to flow an electric current through the electroconductive film and produce an electron-emitting region. Steps (1) and (2) are so conducted that the electroconductive film formed by steps (1) and (2) have a latent image apt to produce an electron-emitting region by the Joule's heat generated by step (3).
