Explanation

It is a materials used for display devices such as cathode ray tube (CRT), liquid crystal display (LCD), plasma display panel (PDP), luminescence diode (LED), etc. The display materials of cathode ray tube (CRT) is a kind of materials that can emit luminescence under electron beam bombardment, which is collectively called cathode ray phosphor. The display materials of the liquid crystal display is liquid crystal, which is a substance that has both the flow ability of liquid and some arrangement characteristics similar to crystal, and the arrangement of liquid crystal molecules will change under the effect of electric field, thus affecting its optical properties. The display materials of the plasma display panel is phosphor excited by ultraviolet light. luminescence diode materials is usually a compound semiconductor composed of gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), indium (In) and other elements.
