Abstract: A Braun tube having an antibacterial coating film, which is manufactured by the steps of dispersing titanium dioxide (TiO2) in alcohol to prepare a dispersion. Then, the dispersion is coated on a Braun tube, and a thermal treatment is then performed. By a photocatalytic reaction of the titanium dioxide contained in the antibacterial coating film, oxygen (O2) and water (H2O) in the air are decomposed into superoxides (O2−) and hydroxy radicals (OH·), which destroy bacteria and mold around the Braun tube and remove bad odor.

Abstract: The display screen 3 of a cathode ray tube 1 is provided with an antistatic, light-absorbing coating 8 which consists of ATO (Sb:SnO2) particles and polypyrrole particles. The coating may be provided with additional layers of silicon dioxide to obtain an antireflective and antiglare effect.

Abstract: An object of the present invention is to provide a screen frame, which is capable of producing clear 3-D video images with a simple structure. The screen frame includes: a frame structure being capable of covering over a screen of a display unit at a prescribed distance away from the screen. Furthermore, the frame structure encloses a window space, whose size is smaller than the size of the screen of the display unit so as to cover parts of the display unit other than the screen. By attaching the screen frame of the present invention, which has a simple structure, to a screen of a display unit, video images on the screen have visual depth, so the user is hallucinated as if he or she is really watching an outdoor scene through a window. Furthermore, the video images on the screen can be made clear by removing influence of external light.

Abstract: A cathode ray tube having an improved safety feature in preparation for the accidental implosion of a high vacuum cathode ray tube is provided. The cathode ray tube comprises a panel, a funnel sealed with the panel, and an implosion preventing band mounted on a sealing portion of the panel and the funnel, further comprising a flexible auxiliary panel which externally covers the panel and whose skirt is adhered to the sealing portion by means of the implosion preventing band. Thus, an external impact is not directly transmitted to the CRT, and the danger due to the implosion of the front of the panel is reduced. Also, the effectiveness of the implosion preventing band can be improved.

Abstract: A method of bonding faceplates (20) to VDU screens is provided in which an adhesive material is dispensed (80) onto a surface of either the faceplate or the VDU (40), the faceplate and the VDU are brought together (90) to force the adhesive material outwards to fill the gap between the surfaces, and the adhesive material layer (41) which is formed is then cured. In a first curing step (100), curing is carried out around the edges of the faceplate to form a seal around the edges. This first step may be carried out in a dedicated positioning tool. A later curing step (120) ensures that all of the adhesive material layer is eventually cured. Positioning (90) in the dedicated tool may use specific reference points on the faceplate and the VDU rather than relying on physical spacers, and may be carried out under servo control of a system for detecting the onset of undesirable gas entrapment conditions within the adhesive layer.
