A display panel is a visual output device that displays information in the form of text, images and videos. It can be a standalone unit or an integrated part of another electronic device such as a computer monitor, television screen, smartphone or tablet display. The type of technology used to create the image on the display panel varies; it could be a cathode ray tube (CRT), liquid crystal display (LCD) or organic light-emitting diodes (OLED). Display panels are commonly used in various industries such as entertainment, education, healthcare and business to present information in an easy-to-understand format.
