  • Patent number: 7898614
    Abstract: The present invention provides a liquid crystal display module which can prevent the generation of display irregularities. The liquid crystal display module includes a liquid crystal display panel and a backlight device arranged on a back surface of the liquid crystal display panel. The backlight device is constituted of a light guide plate and a reflection sheet arranged on a back surface of the light guide plate. The liquid crystal display module includes a flexible printed circuit board having one end thereof mounted on the liquid crystal display panel and the other end thereof formed on a back side of the reflection sheet in an overlapping manner. An insulation sheet is arranged between the other end of the flexible printed circuit board and the reflection sheet.

  • Patent number: 6259206
    Abstract: A cathode ray tube having an evacuated envelope including a panel section having a front face portion including a sloped sidewall, the sloped sidewall and an outer periphery portion being joined at mold match line, a neck containing therein an electron gun assembly, and a funnel section integrally coupling the panel section and the neck together. The sloped sidewall of the front faceplate has an angle which is in a range of 1.5 to 3 degrees to the tube axis, and a reinforcing band attached by a thermal shrink fit technique to and clamped around the outer periphery of the panel section. The reinforcing band is positioned around the panel section at a predefined position in which a circumferential bending line on the reinforcing band is offset from the mold match line of the cathode ray tube toward the neck.

  • Patent number: 6150760
    Abstract: An implosion protection-enhanced cathode ray tube (CRT) includes an evacuated envelope structured from a display panel section, a neck, and a funnel section. The CRT comes with a reinforcing metal band for implosion protection clamped by thermal shrink-fit methods around the outer periphery of the panel. This implosion-protective band may be a metal strip of generally rectangular closed-loop shape. The strip is machined to have bent walls so that it resembles in shape an open-roof dome as a whole. Preferably, the band has its one edge as folded back or "curled" defining a "flip." Upon attachment to the display panel, the band is placed so that the "peak" of each bulged wall is offset in position from a mold match line of the panel toward the CRT neck. With such "band preoffset" feature, the implosion-protective band offers increased locking or clamping forces against the panel thus enhancing the CRT implosion protecting ability.
