Comparison Digma PF-104JR vs Digma PF-733

For digital photo frames, this is the diagonal of the LCD matrix that is actually visible. Measured in inches (inches).

Now on the market there are photo frames with such a diagonal: 6" and less, 7", 8", 9", 10" and more.

For photo frames, as well as for other types of electronic devices using LCD or other displays, the resolution is indicated in pixel points (for example, 800x600 pixels). The higher the resolution, the clearer and more realistic the picture on the frame screen.

Now on the market there are photo frames with the following resolution: 480x234, 640x480, 800x480, 800x600, 1024x768, 1600x900

All photo frames support graphic formats, the so-called. "picture" files (for example - JPEG, GIF, BMP, PNG, etc.).

Specified in megabytes. Usually, flash-type memory is used in modern digital photo frames. Sometimes, if the frame memory is not enough, it can be increased by removable flash cards.

Now on the market there are photo frames with such a volume of internal memory: 1 GB, 2 GB, 4 GB.

— Bluetooth. Technology of high-frequency (radio) communication. It is used for high-speed wireless connection of a PDA with peripheral devices — headphones, manipulators, etc. Unlike infrared ports, receiving and transmitting bluetooth modules do not have to be within line of sight.

— Wi-Fi (Wireless Fidelity). Broadband (high speed) wireless communication standard. Allows you to upload files from a computer to the photo frame quickly, without using cables, memory cards, etc. In some cases, allows you to control the functions of the photo frame directly from your computer.

— USB(Universal Serial Bus). Recently, more and more phones are equipped with a USB interface, which has long been used in computers and other devices. Currently, interface versions 1.1 and 2.0 are mainly used. USB 1.1 supports data transfer rates up to 12 Mbps, USB 2.0 up to 480 Mbps. Today, the third version of the interface is already being tested, which supports data transfer at speeds up to 4.8 Gbps. All versions are backward compatible with each other. In addition, devices can be charged via USB.

— AV output. A connector that allows you to connect a portable device to a TV through a conventional RF antenna input and play the video stored in the photo frame's memory on a large screen, view photos, etc.

— Connector 2.5 mm (mini-Jack). Connector for headphones. Unlike the usual 3.5 mm jack, today it is used relatively rarely in photo frames and related devices.

— Plug 3.5 mm (mini-Jack). The standard headphone jack used in most portable players decades ago. It is widely distributed even now, including in digital photo frames.
