For anyone who knows about e-book reading devices, Sony is probably the most well-known name besides the Kindle. Among the e-book reader brands, Sony Reader is highly recognizable, and Sony invented the first E-LINK screen e-book reader in 2004. Its stunning shape, smooth writing and annotation function, and high-quality PDF reading have won praise from a group of fans, but the expensive pricing, which is several times more expensive than ordinary small-screen products, has discouraged more people.
 
Although it has a good reputation and reputation among consumers, it is difficult to see Sony products in the list of the best readers of major review agencies. Until 2010, among the 12.8 million e-reading devices sold in the world, there are still 800,000 Sony readers, but because of fierce competition, the influence of Sony products has decreased year by year, and the limelight has been surpassed by Kindle. Launched the new e-paper DPT-RP1, hoping to win back the game with this new e-reader.
 
Compared to the poor PDF display performance of small screen machines such as the Kindle, Sony provides a good choice for people who often need to read PDF files. But at the same time, whether it is the performance representative of Sony products, DPT-S1, or the new DPT-RP1, in fact, only support PDF in text format, and the picture reading effect is also average, which is too restrictive at a time when tablets and smartphones have been widely popularized. At the same time, it should be noted that large-screen readers are often not equipped with reading lights due to technical reasons, and Sony is no exception.
 
The DPT-S1 is an electronic reading device based on Sony's paperless office concept, with a screen size of 13.3 inches and a display about the size of an A4 sheet, which is not only excellent for reading PDF but also very suitable for use in occasions such as meetings or seminars. At just 4.8 mm at its thinnest point, the DPT-S1 is more portable than a tablet, and it can also be easily recorded and annotated with a stylus. The screen resolution of this product is 1200×1600pix, which is not as good as DPT-RP1, and the storage memory is 4GB, which is a bit insufficient for a large screen reader, but it supports SD card expansion.
 
In its official definition, the DPT-RP1 is a new type of reader called "e-paper", but in all fairness, in terms of its degree of difference from traditional e-readers, this product is more like an evolved version of the traditional e-reader, in a new and unique presentation, showing Sony's innovative and pioneering heart in this field.
 
The DPT-RP1 is thinner and lighter than the DPT-S1, the screen resolution has also been upgraded, reaching 1650×2200pix, with 16GB of memory, compared to the traditional paper notepad, the DPT-RP1 stands out in that it can digitize text information, the text stored in the machine can be easily shared and changed, and it can also be synchronized with the computer through WIFI or Bluetooth connection. The DPT-RP1 also has a reliable multi-layer encryption function, which uses AES 128 data encryption to better protect important files from theft.
 
The purchase channel of Sony reader is relatively narrow,At present, on the domestic e-commerce platform,Some overseas buyers sell DPT-S1 and DPT-RP1,The price is more than 4000 yuan。
