CRT Simulation

Modern Airbus aircraft facilitate the use of LCDs (Liquid Crystal Displays) to display aircraft navigational and system information. CRT (Cathode Ray Tube) usage has dwindled due to the superiority of LCD technology.

The A320 aircraft we are simulating utilizes CRT displays, part of the EIS (Electronic Instrument System) “1”.  Creating a ‘CRT’ displays requires the use of a LCD  which can fit carefully within the main instrument panel (MIP) without disrupting the other instruments. It is mandatory for the LCD to be extremely thin so it can mount on top of the MIP. Another essential requirement is a wide FOV (field of view) and viewing angle to allow for visibility on the sides.

The LCD model B156HAN01.2 / B156HAN06.1 fits these requirements.  The LCD is a TFT panel with an LED backlight driving circuit. The resolution is 1920 (H) x 1080 (V) with 262k colours.

Glass tinted (~ 20-25 %) to provide a smokey effect has also been installed to achieve the desired CRT simulation.

The next step is to apply adhesive black vinyl borders onto the glass to complete the illusion.

The covers retains its thin profile and can be mounted directly onto the Main Instrument Panel
