Displays & Screen Modules for Microcontrollers
OLED, ePaper, LC displays and alphanumeric readouts: visualize readings and status directly in your project.
Displays: for your microcontroller
Displays for microcontrollers are used for the visual representation of information and states within electronic projects. They make it possible to output measured values, status messages, text, or graphical content directly, making projects easier to understand and operate.
Typical areas of application include DIY electronics, IoT applications, smart home systems, measuring and control devices, or interactive user interfaces. Depending on the display type, simple text, symbols, or more complex graphical content can be shown.
Control is usually carried out via SPI, I²C, or parallel interfaces. For common microcontrollers such as Arduino, ESP32, or Raspberry Pi Pico, extensive libraries are available that significantly simplify the integration and programming of displays.
LCD displays – Liquid crystal displays for microcontrollers
LCD displays (Liquid Crystal Displays) use liquid crystals that modulate light when an electrical voltage is applied. They generally require backlighting and provide clear visibility with low power consumption.
In microcontroller projects, LCD displays are commonly used for text displays, menus, status information, or simple graphics. Classic examples include 16×2 or 20×4 character displays as well as compact color LCDs.
Thanks to widely used controllers and libraries, LCD displays can easily be connected via I²C or SPI. They are particularly suitable for projects where clarity, reliability, and moderate energy consumption are key. You can find a selection in the LCD Displays category.
OLED displays – High-contrast displays without backlighting
OLED displays consist of self-emissive pixels that are individually controlled. As a result, they do not require backlighting and achieve very high contrast ratios.
They are especially suitable for compact projects where space is limited or low power consumption is important. Content such as text, icons, or small graphics can be displayed with exceptional sharpness.
OLED displays are frequently used in portable devices, measuring instruments, or user interfaces. Due to their excellent readability even in low ambient light, they are highly versatile. More models can be found in the OLED Displays category.
ePaper displays – Energy-efficient displays with a paper-like appearance
ePaper displays are based on electronic ink and are extremely energy-efficient. They consume no power as long as the displayed content does not change.
Traditionally, ePaper displays were mainly used in black and white or with an additional accent color such as red. However, multi-color ePaper displays are now also available.
Due to their excellent readability in sunlight, they are ideal for outdoor applications, information displays, or battery-powered systems. They are also ideal for static displays where the content changes infrequently because of their low power consumption. Additional variants can be found in the ePaper Displays category.
Alphanumeric displays – Clear display of characters
Alphanumeric displays are specifically designed to display letters, numbers, and simple symbols. They are commonly used in devices where clear text output is essential.
Typical designs include character displays or LED-based modules with fixed positions. They are easy to control and require minimal processing power.
Alphanumeric displays are particularly suitable for timers, counters, status indicators, or simple user interfaces. A selection of corresponding modules can be found in the Alphanumeric Displays category.
