Pixel Controller
Digital Pixel Control Device

A digital pixel controller is a device that controls the individual LEDs in a LED lighting system. It receives data from a computer or other controller and converts it into a signal that can be sent to the LEDs to control their brightness and color. This allows for precise control over the lighting effects and animation. Some digital pixel controllers also have built-in memory, allowing them to store and play back lighting sequences without the need for a separate computer.

Digital pixel controllers typically use a protocol such as DMX, Art-Net or E1.31 (sACN) to communicate with the computer or other controller. The data sent over this protocol includes information on the brightness and color of each LED, as well as any animation or special effects that should be applied. The digital pixel controller receives this data, processes it and converts it into a signal that can be sent to the LEDs.

A digital pixel controller typically contains a microcontroller or other processing unit to handle the data, and a driver circuit to convert the digital signal into the appropriate voltage and current levels for the LEDs.

Digital pixel controllers are widely used in entertainment lighting, architectural lighting, stage lighting, advertising, and other applications where precise control of multiple LEDs is needed.
