    Flat panel is an electronic viewing technology, which is used in many fields of our lives, such as medical and industrial. Usually used in conjunction with personal computers and mobile devices. It can display text, pictures and videos and so on. In the past, cathode ray tube (CRT) televisions were used which it is thicker and heavier by compared with flat panel, . The thickness of the flat panel is less than 10 cm (3.9 inches). Therefore, flat panel has almost completely replaced the old CRT displays in 2016. Its thinness, lightness, low power consumption, low radiation, no flicker, and convenience make it more and more popular.There are many types of flat panel such as liquid crystal display (LCD), plasma display (PDP), electroluminescence display (ELD), organic electroluminescence display (OLED), field emission display (FED) , Projection display, etc.

    Flat-panel display has two kinds of display device: volatile flat-panel display and static flat-panel display. Volatile display requires pixels that electronically refresh at fixed period to hold mode such as liquid-crystal displays (LCD). Static flat-panel display depends on materials that color states are bistable. Flat-panel keeps the text or images on the screen even though the power turns off.

    Most flat panel took advantage of LCD and LED technologies in the 2010s. Flat panel has higher resolutions which is up to 4K resolution. In addition, it has touch technology. By 2016, some devices that use tablets (such as tablets, smart phones, and less common laptops) use touch screens, and touch screens can be operated by touch.
