"If there is only one book on flat panel displays that is going to be on your bookshelf, then I would highly recommend this one. It will be a text that you refer to time and again for clear and concise explanations of how LCD and OLED displays are constructed and the processes used to make them into commercially successful products. As you use it, you will find yourself drawn in by the clear and colorful illustrations and will find it hard to not read more than you first intended."
