Abstract

PURPOSE:To reflect external light irregularly on the display surface of a cathode-ray tube for display and to prevent data on the screen from becoming hard to see, by spraying particulates of sigid resin on the surface of transparent resin film for switches provided on the surface of the cathode-ray tube and coating said surface. CONSTITUTION:Transparent electrodes 4 and 5 for switches are fitted to the surface of the front glass 3 of the fluorescent material screen 2 of the catode-ray tube 1 for display, and flexible transparent resin films 6 and 7 are vapor-deposited thereupon. A transparent spacer 8 is provided between the electrodes 4 and 5. Further, particulares of transparent rigid resin are sprayed on th surface of the film 7 to form the coating layer 9 which has a finely rugged surface and an about 0.5mum thickness. This layer reflects extenal light irregularly, so that the display never becomes hard to see owing to reflection. Further, the film 7 is protected; flaws are hard to make and the life is prolonged.

う欠点２べ かあった。Conventional configuration and its problems In a display device that uses a cathode ray tube as a display element, a switch made of a transparent resin film and a transparent electrode is provided on the screen to allow instructions and input to be performed on the screen. There is something. However, conventional devices of this kind have two drawbacks: the surface of the resin film reflects external light, making the display difficult to see, and the surface easily scratches.

In the figure, 1 is a display cathode ray tube, 2 is its phosphor screen, and 3 is its front glass. A flexible transparent resin film 6.7 on which transparent electrodes 4 and 5 for switching are attached by vapor deposition or the like is attached to the surface of the front glass 3. 8
is a transparent spacer. Furthermore, as a feature of the device in Book 37, fine particles of transparent hard resin are spray-painted on the surface of the transparent resin film 7 to form a coating layer 9 having a thickness of about 0.5 μm and having fine irregularities on the surface. ing.
