Photo picture frames are an old gadget to show memorable photo or picture on the desk, cupboard, etc. But today with lcd or OLED technology, moving photo picture frames like as in Harry Potter movie is posibble. Fews called its lcd digital frame or OLED photo picture frame. OLED is the newest technology for display that more expensive than lcd. Like a flat screen TV, the lcd digital frame is sleek, elegant and classy. A lcd digital frame can show pictures without having to use a computer or printer. A lcd digital frame is made up of the LCD-panel, the PCB contains the software of the digital photo frame, and the outside frame.   Selected digital photo frames only allow JPEG (Joint Photographic Experts Group) pictures to be shown. But there are some that support other forms of multimedia such as movie clips from MPEG, MP3, or MP4 formats. Special lcd digital frame have the ability to receive and load pictures from Internet sources such as RSS (Really Simple Syndication) feeds, e-mail, and photo-sharing sites like Flickr and Picasa. These special models can normally support wireless (802.11) connections, as well. There also exist lcd digital frames that are compatible with .txt files. You can select many features for your digital picture frame.
Here are some considerations when buying:

• Number of Pictures - LCD digital frames usually just need a camera’s memory card. Others use an internal memory, and usually accept files from USB connection. If you want to store many pictures, you might consider a digital frame with a removable memory card. This will allow you to store more images.
• Portability - Some frames are smaller than others. You may buy a digital picture frame that plugs into a wall, or one that runs off batteries. Obviously a battery powered digital frame is more portable than a plug-in.
• Resolution and Size - The larger your digital picture frame, the more expensive. The common 7 Digital Photo Frame (17.5cm) models show photos at 430 x 234 pixels, while some models stretch every landscape photo to reach an aspect ratio of 16:9 and thereby cause noticeable photo distortion. The 8 Digital Photo Frame is also a very popular frame to buy.

You should also be sure to check user options when selecting a lcd digital frame such as :

• Choice to select the interval between images when in slideshow format.
• Ability to rotate pictures to display them in different modes, like landscape or portrait.
• Choice to transition effects between images.
• Sleep function to allow you to turn the frame off at appointed intervals.
• Ability to alter the colors, contrast or brightness of images.
