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 (multiple variants) / BOE NV156FHM-N42 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.
Certain LCD models may not be appropriate for the centre ECAM display; the wiring ribbon for NVH156FHM-N42 is shorter in length and does not allow it to to fold.
B156HAN01.2 wiring ribbon is sufficient for the circuit board to fold and fit within the EIS1/2 display dimensions
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.
