Digital photo frame has long been a very fashionable gift, its gorgeous appearance, clear display and attractive multiple functions are favored by many people. But how to choose a good digital photo frame? Generally, it can be measured from the following points:
Today's digital photo frames generally have a variety of functions, but their main function is to play photos. Therefore, one of the playback effects of photos - the clarity of the picture is obviously our primary consideration. Compared with the narrow screen with limited field of view, the large-screen digital photo frame has increasingly become the darling of the market. At present, the largest screen on the market reaches 19 inches, and the mainstream size is between 10-15 inches. Of course, you get what you pay for every penny. "The bigger the face, the more expensive the price." Good brands, such as Philips' 7FF1M4 and 9FF2M4, are small The price difference between the screen and the big screen is even more, reaching several hundred yuan! In addition, the picture effect is mainly determined by factors such as "resolution", "contrast" and "brightness". The value of resolution refers to the number of horizontal pixels and vertical pixels on all visible areas of the entire display screen. It is also the most basic point for us to measure the display clarity of the picture. The higher the resolution, the richer the details and the clearer the effect. ;Contrast refers to the measurement of different brightness levels between the brightest white and the darkest black in the light and dark areas of an image. The larger the difference range, the greater the contrast. The smaller the difference range, the smaller the contrast. A good contrast ratio 120:1 can easily display vivid and rich colors. When the contrast ratio is as high as 300:1, it can support the color ratio of each level. The larger the color ratio, the richer the color performance and the brighter the picture. Brightness refers to the brightness of the screen, the unit is candela per square meter (cd/m2) or nits. It is understood that a digital photo frame with a high-definition TFT LCD screen, a high resolution of 800*480 and a brightness of 200cd/㎡ can obtain bright and full color performance in the display effect.
In addition to the main functions, the digital photo frame is a "new thing" and "multi-purpose" is also a great bargaining chip to attract consumers. For example, the new DT-80 can not only display pictures, but also play music. In fact, most digital photo frames can not only be connected to devices such as DSC, MP3, PMP, PC, etc. through the USB port on the body, but also have functions such as dynamic control, subwoofer processing, etc., and can also support MP3, MOV in multimedia formats. , MPEG1, MPEG2, MPEG4, AVI and other format files. Just imagine how beautiful and pleasant it would be to lie on the sofa in a quiet afternoon and listen to the classical music while admiring the changing images of the digital photo frame on the table!
Easy to operate and cheap
The innovation of science and technology makes people's life more convenient, and the fast and humanized operation mode has also become one of the key factors for us to choose digital products. Nowadays, many digital photo frames are specially designed with mini remote control, such as Patriot's F5003, users can easily switch photos with just one click. Not only that, individual digital photo frames also have a certain amount of memory. Generally, the built-in capacity of the machine is between 256M and 512M. If you store a small amount of photos, you can directly use the memory of the digital photo frame to store and play photos without inserting another card. Of course, if individual users have requirements, they can also customize digital photo frames with large-capacity memory. Even though digital photo frames are good, if the price is outrageous, it will still deter ordinary consumers. Therefore, choosing the right price is also an important indicator when you buy a digital photo frame.
