The ink case W7 pushed the 10 inch e-paper book to 2499 in 2019. One year later, the ink case InkPad X shocked four customers at the price of 1699. The electromagnetic stylus is removed, but the cold and warm dual color backlight and fragrant price tag make it the first 10 inch e-book for young people.
Tablets are productivity before purchase and iQIYI after purchase. However, e-paper books can only read books, and can only be used as instant noodles when they are idle, so it is no wonder that e-paper books are an unexpected product.
But after all, it is a learning tool, which is suitable for learning and personal value-added use. As long as it is used, it will benefit a lot. We Love to play computer games I still think we should use the evaluation to do some more e-books for science popularization Amway, so there will be a large space of science popularization below, hoping to help those who want to enter the e-book pit.
notes preceding the text of a book or following the title of an article
In this era, people who also buy e-readers are certainly not ordinary people. If not a local tyrant, he/she must be a person who is willing to pay a high price for a 10 inch screen e-book.
This machine guy also wants to bite his teeth several times to get a 10 inch screen e-book, and then look at the starting price of 3000. Poverty tells me that 6 inches is not small at all, and the Kindle on hand is enough!
Popular Science and Parameters of E-book
When it comes to e-readers, I have to mention Ink and Yuantai. E ink is a non luminous screen using electronic ink (with microcapsule or micro cup structure), which has the advantage of no flash and no power consumption during framing, no eye damage and power saving. The disadvantage of normal ink screen is also extremely obvious. Black and white, and page turning and refreshing are extremely slow, which is a true PPT level.
Now there are "High Brush" and "Color Ink", but don't expect too much. Although the prices are high, they are "barely usable". For most people, an ordinary black and white ink screen is true.
Size comparison between 6-inch, 7-inch and 10-inch e-paper books and iPad mini
Because Yuantai is basically the supplier, the e-paper books in the market focus on several screen sizes:
6 inches: Low resolution Kindle Youth Edition/Xiaomiduo E-book (about 600 yuan), 300PPI Kindle PaperWhite (about 1000 yuan);
7 inches: The most famous is the 300PPI Kindle Oasis (around 2600);
7.8 inches: Aragonite BOOX Nova2, Get Reader, Chinese R7S, Boyue T80D, etc. (1200-2500);
10 inch level (including 10, 9.7 and 10.3 inches) and 13.3 inches: their previous prices were more than 5000, and they were basically equipped with a stylus, which was specially designed for big bosses to sign and read official documents. In the past two years, the price of 10 inch products has begun to loosen. At around 3500, normal people without money capacity can afford to buy them.
Because the screen size is marked by the diagonal length, even though the ink screen size looks small, it is almost 4:3, so the actual area is about 1.26 times that of mobile phones of the same size.
6 to 7.8 inch e-paper books correspond to the pocket book level, 10.3 inch e-paper books correspond to A5 paper with white edges removed (most domestic books are of this size), and 13.3 inch e-paper books correspond to A4 paper (magazine level).
There are also 9.7-inch and 10.3 inch products that are close to the Ink Table InkPad X. The 10 inch screen of Inkpad X should be the first new product of Yuantai (mainly reducing PPI to reduce costs). Because the screens are basically made in Yuantai, the screens of machines of the same size and resolution are basically similar (mainly in the backlight reading lamp).
Parameters of several e-books of similar size:
Mohan is a Xiaomi ecological chain enterprise. Last year's Ink table W7 The screen is slightly larger, the fineness is slightly higher, and it has handwriting pen and annotation function, so it can be regarded as half a production worker. There is handwriting, but no backlight;
Ink InkPad X The choice of is very accurate. Its target is the reading crowd, so it adds a reading light and removes the attached electromagnetic pen (capacitive pen is supported, but the official pen has not yet come out). For the first time, there are official protective shells and 180 day VIP;
Aragonite BOOX Note2 It is the most special one. In fact, it is classified as an ink screen tablet rather than an electronic book reader. Its performance configuration is closer to the normal Android tablet, even with fingerprints, at the cost of price and endurance;
iReader Smart X The main features are handwritten OCR, intelligent search, voice recording to text, and other functions like the omniscient eye on the Kindle, which should be targeted at student users;
Sony DPT-CP1 Of course, the features are Dafa's logo and 240g sci-fi slim (lighter than some mobile phones and 6-inch e-books).
Products close to the size include: Hanwang EA310 (3500 yuan), Guowen Yibentong 3 (2400 yuan), Boyue Likebook alita (about 2600 yuan) Haier also has a 9.7-inch 1200 * 825 screen Leadpie (435g, 3900mAh battery, 2099 yuan). It can be seen that the price of large screen e-books is loosening.
The bloody lesson tells us that the less functions of e-books, the cleaner the better, otherwise you can't help but toss about. Reading or instant cover is the most suitable function for e-book readers. Loudspeakers, Bluetooth and so on, I feel that they are polluting the absolute field of reading.
Appearance and feel
Both the machine and the official protective cover are in pure white packaging, and the accessories are only Type-C data cable and instructions.
The official protective cover is fixed with adhesive, simple style, light weight, with magnetic switch screen function.
Ink table InkPad X has narrow edges on three sides, and the fog surface frosting cover plate on the front is very small and fine. Slightly curved back, skin like coating. The fuselage structure has only three large parts, which is extremely simple: the back cover and side cover are integrally formed, and the screen and the integrated fuselage are connected with smooth washers. In addition to the wider chin, the appearance is still very advanced, especially the back.
There is a symmetrical speaker opening at the bottom (in fact, only the left side is the speaker, and the right side is the decoration), and there is only a red power button on the top, which is the symbol of the ink table. There is nothing on the side.
Kindle PaperWhite, InkPad X, iPad mini and Kindle Oasis
The back is covered with a skin like coating with large grit size, which is dry and comfortable, I like it. The screen washer is slightly higher than the screen, and the side chamfer is a bit sharp.
The 10 inch 358g is much lighter than the iPad of similar size (the 3rd generation air is 464g, the iPad mini 5 is 308g, and the 7th generation iPad is 493g). But without the shock of the 240g magic weight of Sony Dafa DPT-CP1, I was a little disappointed when I picked up the real machine.
The weight of Ink Table InkPad X is slightly lower than that of similar products, but it can't be held in a single hand for a long time like Dafa. It can only be held comfortably for a long time by leaning against the table with help. In addition, the narrow border must touch the screen when you hold it. Fortunately, many apps such as Watch More and WeChat Reading in the store (the function of quick display of comments has been canceled) are anti touch, and third-party apps need to see whether the click function is triggered.
screen
Base color and fineness
Kindle PaperWhite, Ink InkPad X, Kindle Oasis
E-paper books must be a bit grayish yellow. The base color of Ink InkPad X is slightly darker than that of the high-end Kindle series (Yuantai's big customers do have advantages), but the gap is not big.
Is 200 PPI enough? It is enough to read words. After all, there are still a large number of desktop monitors with 24 inch 1080P. Don't we survive the big fruit with only 92 PPI? What's more, the higher 10.3 inches is only 227 PPI.
Top to bottom are Kindle PaperWhite, Ink InkPad X, Kindle Oasis
The fineness is certainly not as good as the 300PPI of the 6/7-inch advanced Kindle, but the InkPad X on the ink table is also 10 inches. If you look at the smallest font several times larger than the Kindle, the viewing distance is far, and the fineness is not a problem. Write Wheel Eye users can change to the normal refresh mode. A new font will improve significantly.
In the past, when viewing photocopied PDF on 6-inch Kindle, horizontal screen or intelligent rearrangement was required. The original A4/A5 books were squeezed into 6-inch screen, which made the experience very sour. Now the 10 inch screen can display most of the book content at the same size, which is close to the size of a physical book, without zooming.
When displaying the contents of magazines and papers, the fineness is enough. After all, the horizontal resolution is 1200 (higher than most desktop office displays). All the contents can be seen clearly. Just look closer. But the final solution still needs to add money to the 13.3-inch version.
Contrast/Tolerance
The gray scale of the ink screen is not enough. If you want to display strong and clear text, you need to increase the contrast. If you increase the contrast, the picture will become black and confused for the time being.
So the e-book app can adjust the contrast, while the InkPad X system level has five levels of contrast, and the notice bar can be adjusted directly. When you read comics, you can directly pull to the lowest, so there will be more pictures. When you read a book, you can push and pull as appropriate.
Reading lamp evenness and light leakage
Warm light level 24
Cold light level 24
Ink table InkPad X is a 24 level cold and warm dual color reading light. The principle is to place LED light source and light guide plate under the screen. This has been the case since the Kindle Paperwhite 7 or 8 years ago, and it will be the same in 2020.
From the top limit angle, you can see that the cold and warm backlights of InkPad X are alternately placed at the bottom of the screen, 10 for each. When the backlight is turned on, the screen will be a little gray when viewed from the top (because it is flushed). Other angles are OK.
Double color salad, highest brightness contrast, Kindle PaperWhite, Ink Table InkPad X, Kindle Oasis
Pure warm light maximum brightness contrast, Kindle PaperWhite, Ink Table InkPad X, Kindle Oasis
Pure cold light maximum brightness contrast, Kindle PaperWhite, Ink Table InkPad X, Kindle Oasis
Warm light has a higher degree of warm color, close to orange red; The cold color of the cold light is low, slightly bluish white; When the double salad is full, it will still be orange red. The eye protection party is satisfied with this wave. It has turned into a yellow screen. The Kindle only has monochromatic light, which is just used as a color temperature contrast tool.
The two colors can be mixed, equal to 24 * 24=576 level adjustable, and the precision is too high to use. The maximum brightness is one level lower than that of the high-end Kindle series, but the backlight is used to cope with the dark environment, and the brightness is too high to use.
The uniformity cannot be expected to be too high. The InkPad X on our ink table also has the problem of high and uneven brightness at the bottom, especially at the lower left corner, which is really touching. Fortunately, the leakage at the bottom has little effect.
Refresh and page turning speed
Play at the original speed, which is relatively fast in the e-book
The system comes with two modes: normal refresh and fast refresh, which can be quickly switched in the notice bar. When reading a book, the two modes are very small, both of which are local refreshes. They will not refresh the whole page as the old ink screen does. They will not be too stimulating to users who have not used the ink screen.
In case of large pictures or comics, there will still be large areas of black and white flashing. The text in the fast refresh mode and even the residual image of the picture are OK. The refresh speed and shadow control have improved, but not much. The progress of ink screen technology is too slow.
The new ink screen in 2020 will still be the culprit that slows down the response speed of all operations and makes the e-paper book unable to slide screen (constant flashing will blind you, and the PPT refresh rate is too terrible).
In general, my comprehensive evaluation of the Ink screen is above the average level, not as good as the high-end Kindle series, but the gap is small.
Graphic resources
Image and text resources can be ignored directly. InkPad X is an open Android 8.1 and does not block the installation and file system of third-party apps. It doesn't matter which e-book platform you were originally a user of. Kindle, WeChat Reading, Palm Reading Mall, and JD Reading app are easy to get.
Seriously, the book resources that we see more now, whether the number of books or the price, are still a long way from Amazon. In addition, many people often use WeChat reading to "read later" because of WeChat official account. In this era, binding a reader to a reading platform is tantamount to suicide.
Ink InkPad X comes from the factory with many apps. The recommendation and classification of the book store are incomplete. The elements are too large and the operation is inconvenient. The current e-book operation experience is still too bad. Try to avoid complex operations. Just read more apps on your mobile phone and select good books. Automatically synchronize the books and progress. Don't bother yourself.
The five reading apps (WeChat Reading, JD Reading, Jingdu Tianxia, KOReader, Netease Snail Reading) cooperated by the official store are better optimized. In addition, there are many readers specially adapted to the ink screen on the market. Search engines search a large number of them, so I will not repeat here.
DPI customization function (DPI range 200-450)
Zhihu under 450 and 200 DPI
The system of Inkpad X can actually customize the DPI of each app (that is, it can control the size of various elements, which is a function that can only be achieved after normal Android root). Therefore, the display adaptation of mobile app under third-party app stores is not a big problem. The main problem is that the sliding operation of the ink screen is too sensitive to prevent accidental touch.
System&Performance&Smoothness
The system itself is very simple. The home page and the return touch button are placed on the upper left corner of the notification bar, and the left side is home to four major function entrances. The extra schedule function is too troublesome to input. Whether there is calendar synchronization function is basically a foil.
The ink table system has obvious MIUI flavor, especially the notice bar. There is a very convenient levitation ball, which can be customized by single and double clicking. The screenshot, lock screen, brightness adjustment and other functions are available, which is very easy to use.
Its system is open so that even the system font can be changed (TTF font files can be changed by directly placing them in the Fonts folder), and even retains the developer mode. The machine also has a capacitor button that can be customized to "return or return to home page".
At this stage, there are still some bugs in the system. For example, the voice cannot be turned off. Although there is a control switch in the notification bar, the notification push cannot be blocked for the time being, and the third-party application has been restarted once or twice.
Developer Mode
The best thing about this system is that it is open. When you see the file manager on an Android device, it means that the door of the world has been opened to you. Ink InkPad X has opened storage, reading and writing, and can connect to computers, bluetooth, Baidu Cloud, ink case messenger (disguised as cloud disk, with 500M space by default), traditional local FTP. Ink InkPad X can be used as long as it is a file transmission scheme that can be used by Android devices (Android is good).
Both old photocopies and various apk files can be installed directly (Geekbench 5, WeChat and several reading apps cannot be installed temporarily). Of course, the first step is to install an app store such as Ku'an and APP Bao.
The performance part of InkPad X should still be the W7 Quanzhi B300 (sun8iw15). It supports stylus natively. The official data only indicates that the system is Android 8.1. I don't know whether it can be upgraded to Android 9 or 10 in the future.
CPU is 4-core [email protected] , maximum output 2332x1650@100Hz , eMMC 5.0 flash memory, GPU is Mali400 MP2, can be H.264/H.265 1080P@60FPS Video decoding, even temple escape can easily run (PPT picture can't play anymore).
For entertainment, its GeekBench, Pi and RAR scores are higher than expected, similar to the ancient Xiaomi 2. After changing the refresh rate to fast refresh, the system response is still OK. 2G memory can be easily adapted to several apps in the official store. If you open three reading apps in a three-party app store, the first one will be squeezed out of the background.
Bluetooth&Music&Voice&Endurance
Inkpad X has speakers and microphones. The iFLYTEK input method can be used directly for speech recognition, and Bluetooth headset, mouse and keyboard can also be used. The native player does not support the APE format, but even the flac format auditions of more than 100M can be played in seconds. The volume is very high, but the sound quality will be acceptable. On the whole, it is very suitable for listening to books and listening.
What's the future of e-book, a product that lasts for half a month? When WiFi and backlight are officially turned off, 6500 pages can be turned continuously and the standby time is 45 days. The data is a bit exaggerated and extreme, but it is not a problem to read for an hour every day and persist for half a month.
Summary&suitable for people
If the main purpose is content consumption, the reading experience of 10 inch e-book can be expanded from iPad to 6-7.8 inch e-book on all reading platforms, old quality photocopies, magazines and papers. Of course, portability is an exception.
For students who need a stylus to make notes, comments or notes in class, or who want to replace printed courseware with electronic paper books, it is recommended to directly look for 10 inch screen products with standard electromagnetic stylus such as Ink Table W7, Hanwang, iReader. Ink InkPad X is targeted at reading and content consumption. Even if the official capacitive pen is really created, the chances of experience will be worse than that of our own W7.
The price of 1699 yuan for Inkpad X of the ink case, which can be bought without the ability to launch money, also officially enters the price range that normal people may consider. In addition to a few bugs, such as voice failure, there are not many places to drop the chain. To sum up, what can we say other than "true fragrance"?
