Description

AVIONIC MULTIFUNCTION DISPLAY DEVICE
Field of the Invention The present invention relates to a liquid crystal screen (LCD) based display device which enables to display data about the fiight and the mission in aircrafts.
Background of the Invention Pilot/s and related personnel are informed using various display units in aircrafts and helicopters. Many values such as altitude, speed, position of the flight, flight direction, engine speed, etc. can be displayed in these display units continuously. Apart from these, specifications such as course of flight and duty to be performed can be displayed over these display units as well.
There are no digital and analog video input and output interfaces that will support complex avionics architectures in some display devices used in aviation today. Therefore, difficulties may be experienced in determining interfaces of products that can be used in system and cockpit designs.
Liquid crystal displays (LCD-Liquid Crystal Display) are used in display devices used in aviation today. A backlight light source is used in order that these displays are illuminated. Fluorescent lamps are used as backlight light source in the state of the art. Use of fluorescent lamps leads to flicker problems especially in horizontal and vertical lines with single pixel thickness in the display by causing the light to diffuse irregularly.
The United States patent document no. US2008084707 discloses a display panel wherein LED backlight is used for avionic indicators. The United States patent document no. US6841947 discloses a system and method for controlling a LED matrix which is used as a backlight in an avionic display.
