Patents Assigned to Aerospace Display Systems
  • Patent number: 5539552
    Abstract: A protective member for a display device such as an LCD display mounted in a display system provides protection to the display device against ultraviolet light and shock. In one embodiment, the protective member is mounted between the display device and at least one source of light energy which includes both ultraviolet light energy and visible light energy. In another embodiment, the protective member is used to actually fabricate the display device. The protective member blocks generally all of the ultraviolet light energy which has a wavelength of between 200 to 390 nanometers, while transmitting at least 90 percent of the visible light energy having a wavelength greater than approximately 410 nanometers. The protective member has a thermal coefficient of expansion (TCE) of between 45.times.10.sup.-7 /.degree. C. and 60.times.10.sup.-7 /.degree. C., so as to be useable with present day manufacturing processes for such display devices.
