LEDs & Displays
60 products
LEDs and display modules are essential visual output components for electronic projects. This category includes standard 3mm/5mm LEDs, high-brightness power LEDs, RGB LEDs, LED strips, 7-segment displays, dot matrix displays, character LCDs, graphic OLED screens, and TFT touch panels. Each is available in various sizes, colors, brightness levels, and communication protocols to suit your needs.
Application Areas
These components are used in scoreboards, counter circuits, user interfaces, wearables, smart home devices, and industrial control panels. Their low power consumption and easy drive capability make them particularly popular in battery-powered portable projects.
Selection Criteria
To choose the right product, first determine the operating voltage, current requirements, and visibility needs. For instance, a high-contrast OLED display is ideal for a dashboard, while a simple LED suffices for basic on/off status indication. Driver IC compatibility (such as MAX7219, HT16K33, SSD1306) and communication interface (I2C, SPI, parallel) directly affect the prototyping process. For outdoor use, ensure the display is sunlight-readable (brightness, transflective panel).
Common mistakes include connecting an LED without a current-limiting resistor, selecting the wrong display library, or attempting to drive a 5V module directly from a 3.3V microcontroller without level shifting. Reviewing the datasheets of the products in our category can help you avoid such integration pitfalls.
