At this year's VDI International 'Plastics in Automotive Engineering' conference, Evonik demonstrated the special neutral grey of PLEXIGLAS® PMMA. The PLEXIGLAS® series of dark grays is particularly suitable for the production of multi-functional panels with black panel effects. The display using this effect can appear as a uniform black panel - when it is turned off, it can use the backlight to display the information of the monitor, or when it is activated, it can display the ambient lighting with high color accuracy. , Combining large-scale decorative panels and displays into multi-functional panels or integrated displays is a major trend in the automotive industry. Based on the special material colors, this transition from panel to display becomes more and more difficult to identify. The PLEXIGLAS® Neutral Grey fits perfectly into this type of application.
