The difference between the digital screen and the analog screen of the LCD liquid crystal display is not explained here about the technical principles. As a user of a digital photo frame, their performance should be considered. The differences are as follows:

Digital photo frame has already become a very fashionable gift. Its gorgeous appearance, clear display and attractive multiple functions have been favored by many people. But how to choose a good digital photo frame? Generally can be measured from the following points:

1 Placed in a reasonable position, digital photo frames are complex electronic devices that cannot withstand collisions caused by falling.

2 Try to be moisture-proof. Digital albums are easily damaged due to moisture and liquid splashes.

3 Always clean the surface and screen of your digital photo frame with a soft, dry cloth.

4 When using for the first time, fully charge the digital photo frame. When the battery is fully charged, the battery indicator will go out. This process can take 3 hours or more. The digital photo frame starts to fully charge the built-in battery only when the battery level is below a certain value. This design can avoid unnecessary battery charging, thereby extending the battery life of the digital photo frame.

5Using the recommended resolution is usually best.

6 Check the power cord frequently.

Although the electronic photo frame has many pictures and many models, the only important ones are the "LCD screen resolution", "LCD screen level", and "frame function".

By "LCD screen resolution" points:

7-inch TFT LCD liquid crystal display, ordinary resolution (also known as analog screen), pixels 480 * 234 * RGB = 1440 * 234 = 336960 colors, which is lacking compared to computer monitor clarity and low price.

7-inch TFT LCD liquid crystal display, ultra-high resolution (also known as digital screen), 800 * 480 * RGB = 2400 * 480 = 1152000 pixels, equivalent to a 7-inch (15cm * 9cm) cut from a computer LCD ) Area is even clearer than some low-resolution computer LCD monitors, and the price is higher.

According to "LCD screen level":

Bright points are visible points that always show a certain color on the screen, bright lines are visible lines

1. AA screen: There are no bright spots, bright lines and other superior products in A screen. They are commonly known as "buyers", and they are recommended for purchase.

2. Screen A: qualified products, but there are a certain number of bright spots, generally less than 3, if you do not mind the bright spots, you can buy;

3. B screen: for industrial use, there are many bright spots, and defective products cannot be purchased;

4, C screen: there are bright lines, bright spots, defective products, can not be purchased.

According to the "frame effect", there are single-acting, multi-acting ordinary version, multi-acting LCD TV version, and multi-acting super high-resolution version.

After the film exited our ordinary people's life, the classic process of shooting-developing film-printing photos also gradually disappeared from us. Instead, there are a large number of digital camera user groups and a wide variety of storage media. The digital photo frame is currently the best way to play back these photos. As the core product of browsing digital photos, the digital photo frame correctly meets the needs of consumers.

The traditional 35mm camera has been basically replaced by a digital camera. After the film has been launched into our ordinary people's lives, the classic process of shooting-developing film-enlarging photos has gradually disappeared from our side.

Many people don't understand what the charm of photo frames is. The digital photos taken nowadays have started to show a geometric progression. If you want to print these photos out for aftertaste and appreciation, you will waste a lot of money. Besides, traditional photo frames and photo albums can no longer bear the heavy responsibility of preservation. The digital photo frame will completely liberate those backlog of digital photos, so that every moment worth remembering in your life will never be buried in the hard disk. Digital photo frames can be used to beautify homes and construct exquisite life enjoyment. Share happiness and show success; bring to parents to ease thoughts; or bring into the office to relieve work pressure.

Compared with traditional photo frames, digital photo frames also have many advantages. The appearance of the digital photo frame is very close to the traditional photo frame, and it is more refined, but it can store more photos, unlike the traditional photo frame, which is single. Moreover, the digital photo frame has been developed for 5.6 years, and the pixels have grown from 200W pixels to the current Above 600W pixels, the picture accuracy has been greatly improved. The photo frame has also changed from the mainstream 4-inch screen to the 8-inch screen, and the visual effects brought by it are definitely unmatched by traditional photo frames. In addition, the role of digital photo frames is also very many. It has departed from the definition of ordinary photo frames. Playing movies, enjoying music, calendars, clocks, etc. make multimedia more close to life.

More development status:

Since digital photo frames are basically manufactured by domestic manufacturers, in order to save costs, ordinary TN LCD screens are used, and the angle of view is extremely narrow, which loses the significance of the photo frame. Furthermore, due to the development and price reduction of tablet computers, 300 yuan tablet computers can completely replace digital photo frames and even have more Excellent display effect. So regular manufacturers no longer develop digital photo frames (year unknown).

Only cottage workshops are still making low cost, limited function (dedicated) digital photo frames with high display quality. Multifunctional digital photo frames are completely replaced by tablets.
