A Dot Matrix Display is a two-dimensional array of LEDs that can be used to display characters, icons, or symbols.
This module works similarly to the 0.96-inch OLED display, but it uses a different driver chip. It provides a larger display with a 1.3-inch diagonal dimension, while maintaining the same resolution of 128×64 pixels.
OLED stands for Organic Light Emitting Diode. An OLED display is self-illuminated, meaning it does not require a backlight since each pixel emits its own light. This results in better contrast, thinner design, and lower power consumption compared to traditional LCDs.
A Seven Segment Display is a type of display composed of seven individual LED segments arranged to form numerical digits and limited alphabetic characters. Each segment can be lit independently to represent numbers from 0 to 9 and certain letters. A single digit therefore consists of seven LEDs or segments.
LCD stands for Liquid Crystal Display. It utilizes the properties of liquid crystals to produce visible characters or symbols. Since an LCD does not emit light by itself, a backlight is often required to make the display readable, especially in low-light conditions.
