How does a digital photo frame display images?

A digital photo frame displays images by utilizing an LCD or LED screen to show the photos. The frame connects to a computer or a storage device such as a USB flash drive, SD card, or Wi-Fi network, allowing users to upload their photos to the frame's internal memory or access them remotely.

Once the photos are loaded onto the digital photo frame, the device cycles through the images, displaying them one by one. Some frames offer options for displaying slideshow presentations, with transitional effects, specified time intervals, and even added music or video playback capabilities.

Many digital photo frames have built-in sensors or settings to adjust the screen's brightness or color balance based on ambient light conditions, ensuring optimal viewing. Some advanced frames also offer additional features such as touchscreen navigation, gesture controls, or the ability to display other media, like videos or music.
