# Introduction

There are various display emulators available for running code against, for debugging and screen capture functionality:

- The `luma.emulator.device.capture` device will persist a numbered PNG file to disk every time its `display` method is called.

- The `luma.emulator.device.gifanim` device will record every image when its `display` method is called, and on program exit (or Ctrl-C), will assemble the images into an animated GIF.

- The `luma.emulator.device.pygame` device uses the pygame library to render the displayed image to a pygame display surface.

Check out the examples on how to use the luma.emulator devices.
