Most domestic PDF files will crash if they are opened for more than 50M! Hanwang is no exception! This is what I use! I know.

And the screen of electronic paper books is easy to be damaged. A broken screen costs 500 yuan!

I'm using electronic paper books myself now, so I'll give you some attention and not tell you the general functions of electronic paper books.

Recommend Amazon kindle3. I use Amazon kindle2, which is the second generation. If it is the third generation, many functions have to be changed!

I want to emphasize one point here! One of the electronic paper books is the electronic paper book (electronic paper book ink screen, which is very close to the realistic effect of paper. The screen won't glow, so turn on the light when reading at night! ) E-books are TFT LCD screens! The difference is huge!

Electronic paper books and e-books are completely different! Electronic paper books use electronic paper and ink screens, without electricity! Only when turning pages, pressing the button will be a bit troublesome.

E-books use TFT LCD, which is the same screen as mobile phones, MP3 and MP4.

Amazon kindle3 uses a 6-inch screen, 16 grayscale! Remember! Buy electronic paper books. Now many people use 8 gray scales! In electronic paper books, gray scale is equivalent to the resolution of LCD TV. At present, the highest gray level of electronic paper ink screen is 16. If you look at books and comics with a gray scale of 16, the font will be darker! Closer to the display effect of paper!

Amazon kindle3 can surf the internet, use WIFI and 3G network, and use 3G network card is free! It costs nothing! You don't have to doubt this, I use it!

The memory of the machine is 4G, and 3500 books are pre-stored. As for the battery, because the electronic paper and ink screen of the electronic paper book will not cost a little electricity, it will only cost a little electricity if you press the button when turning pages. If you turn pages, you can turn 10000 pages. As for standby, it takes 30 days without surfing the Internet, and 15 days after turning pages! It's been a long time.

Finally, I tell you that most domestic electronic paper books will basically crash when PDF is opened for more than 50M! Anyone who has used electronic paper books will know that it took me four seconds to open the PDF of 150M on Amazon, and it didn't crash. It's not that I belittle domestic products, most of them are. Besides, don't buy brands like Taipower. I know that the brand of Taipower can be bought for 799 yuan, but there are many problems with Taipower! You can check this online!

That's all I want to say. The price of Amazon kindle3 is about 1300 yuan!
