The concept of photoelectric parameters


LCM photoelectric devices include LCD PANEL (LCD PANEL, LCD screen, LCD glass, integrated LCD) and backlight.
LCD is a kind of optical switch, which can control the performance of light through, partially through, and not through when it is powered on. In essence, it is a device that modulates light flux under the action of electricity.
BL is a light emitting device that turns the light emitting diode into a surface light source, which is the main light source of LCM.
