In a previous blog post, you can see an image of the laptop with the EL display on board the space shuttle. EL technology has made continual and dramatic improvements, but you'd have to say that a display that can withstand g-force environments is an ideal solution for the most challenging and demanding applications.
Planar's EL displays have significantly improved over the past 25 years. Besides improved display brightness and contrast, improvements have been made to reduce power consumption and improve enhanced shock and vibration resistance.
What project do you have that would benefit from an EL display?
