Knowledge about Screen Size and Type for Digital Photo Frames

Screen Size and Type for Digital Photo Frames

Digital frames range in size: from 1.5-inch keychain displays to 32-inch wall-mounted behemoths. Typically, most frames are in the 5- to 15-inch range.
size and application: Smaller frames (under 15 inches) are ideal for positioning on a desk or coffee table. Larger frames are optimal for mounting on a wall or used for digital sign display purposes.

measuring frame dimensions: Some manufacturers use the outer dimensions of the frame--not the screen--to indicate screen size. Always check the technical details for exact screen size.

LCD and TFT: Most digital photo frames come with LCD (Liquid Crystal Display) screens. However some have TFT (Thin Film Transistor--a subtype of LCD screens that use separate transistors to control each pixel. Also known as "Active Matrix" displays).

OLED: A small handful of digital frames are now using OLED display technology for their screens. OLEDs (Organic Light Emitting Diode) screens are composed of slender films of organic compounds that create light via the application of electricity. OLEDs can provide brighter, sharper image displays and use less power that the conventional LCD as they don’t require a backlight. In turn, this also means OLEDs can be a lot thinner than an LCD. Because OLED technology is fairly new there are some drawbacks, such as expense and durability. Expect to see an increase in OLED digital frame displays throughout 2009.

viewing angle: Ensure the frame you wish to purchase has a wide viewing angle, therefore making it easier to see images displayed on the frame from various positions in a room.
