The PCD8544 display, also known as a Nokia 5110 LCD, is a single color 84x84 LCD display. Data is sent to the display via SPI. The also typically also include an led backlight controlled via a single pin.

These displays have excellent visibility in daylight, even without the backlight, making them a good choice for builds with low-power restrictions and require visibility is bright light or daylight.
