Heating device for fitting to display instruments in motor vehicles uses a conductive polymer to prevent any restriction of beams of light from a display instrument in a motor vehicle or any reduction in its brightness

摘要

A conductive polymer (6) prevents any restriction of beams of light from a display instrument (1) in a motor vehicle or any reduction in its brightness. This means that the polymer can be applied to a freely post forming substrate (4) and so allow for later use without any problem, so that production cost can be considerably reduced.
