By careful design of the display and installation, it is possible to produce a display with adequate luminance
  • Anti-Glare Film on Planar Electroluminescent Displays - AN135
    Planar offers many electroluminescent (EL) displays with a very thin polycarbonate film of anti-glare (AG) coating laminated onto the display. By providing a microscopically rough surface, the resulting construction diffuses glare while transmitting 90% of the luminance of the clear display glass

Because these displays have wide viewing angles (> 160 degrees) and operate at. video rates, TFEL technology has all the characteristics required to produce high information. content flat panel displays with the image

Using in-plane switching technology (IPS), the LM181E05 boasts a 160-degree viewing angle, high luminance of 250 cd/m^2, a color saturation of 62 percent, a contrast ratio of 350:1, and a response
