The display panel is what shows all of your device's visuals.

Although there are a wide variety of display panel types and sizes (LCD, LED, OLED, AMOLED), they're typically the most prominent feature of the device, which makes them very easy to identify. Look for a ribbon cable that connects the panel to the rest of the device.

A growing number of modern devices, such as the iPhone, are combining the digitizer and the display panel into a single display assembly. This means that if either component fails, you need to replace the entire assembly.
