Plagiarism is quite a bad thing because if you plagiarize, you are copying and pasting other people's work and using the work as yours (even though you change the sentence structure/ some words, it is still plagiarizing.) Fair use means un-biasness.
        
             
        
        
        
Answer; Electric Paper Display
Explanation:
<em>"PDs are extremely thin and only require power when a new image is requested. Instead of a traditional display that uses backlighting to illuminate pixels, an EPD is based on the scientific phenomena known as "electrophoresis," the movement of electrically charged molecules in an electric field."</em>
Above is the definition, as you can see it resembles your question greatly so this is most likely the answer you're looking for.
