Digital photo frame

Digital photo frames are liquid crystal displays in the form of a picture frame that can store digital images and display them independently from a computer. For the exchange of data they are with USB port, equipped a memory card reader or other ports.

The digital photo frame has been popular in the early 2000s, after the falling cost of manufacturing ( technically related ) LCD and TFT monitors made ​​him marketable.

Types

A digital photo frame is mainly composed of a TFT screen and a processing unit for converting the data and a memory card reader. The mains and / or battery-powered device receives its data usually through a memory card via the network (wired / wireless ), Bluetooth or through an Internet connection.

Sizes

Commercial models have a screen size from 7 to 10.4 inches ( 18-26 cm). There are also mini desktop models with for example 1.8 ", 2.4 " and 3.5 " (approx. 5 to 10 cm), as well as key chain approximately 1.1 " and 1.5 " (2.5 to 3 cm).

Functions

Digital photo frames are classified into three broad categories:

The images under the first category can really only display images ( in JPEG format ), but many models offer the option of timed alternating display of the images. Multimedia photo frame can also play music and videos. Some models of the last category can also connect to the Internet and download images from RSS feeds, email or photo sharing sites like Flickr or Picasa there. Many of these models also have the opportunity to share images wirelessly (usually via Bluetooth). In addition, models with DVB -T receiver on the market, which can be used as a mini TV.

Partial coloring can also be manipulated, eg blue tint, or zoom functions are available.

Due to the increasingly flexible functionality arise also creative ideas on how the device can still be used for completely different purposes, for example as a display for an embedded system.
