LCD Displays ModulesLCD display modules are devices that are used to display text, images, or video on a screen. They typically consist of a liquid crystal display (LCD) panel, which is a thin and flat display technology that uses the properties of liquid crystals to modulate the transmission of light, as well as a backlight, which illuminates the display from behind, and an interface circuit, which connects the display to a microcontroller or other device. LCD display modules are commonly used in a wide variety of applications, including consumer electronics, instrumentation, and industrial control. They can be used to display a wide range of information, from simple text and numbers to complex graphics and video.
