1. Display Quality
The display quality of an e-book reader depends on its resolution. For regular text reading, a moderate resolution is sufficient, while higher resolutions are suitable for users who want to view high-quality content like comics or photo collections.
2. Size and Weight
Choose the size of the e-book reader based on your portability needs. 6 to 7 inches is a common and convenient size for carrying around, while screens larger than 7 inches are suitable for extended reading or users who require a larger display. In terms of weight, a lightweight reader is more suitable for prolonged holding. It is generally recommended to choose a model weighing less than 200 grams.
3. Screen Type
o LCD Display: Rich colors and fast page-refresh rate, but higher power consumption and potential eye fatigue during prolonged use.
o E-Ink E-Paper Display: Provides a reading experience similar to paper, is more eye-friendly, and consumes less power. However, the refresh rate is slower. Traditional E-Ink screens are black and white, displaying only grayscale images and text. However, with technological advancements, E-Ink displays with color capabilities have been developed.
4. Black & White/ Color Screen
If your primary focus is reading books, novels, and documents with pure text and you prioritize battery life and outdoor reading capability, a black and white display might be your preference. However, if you have a higher demand for image content or you value the ability to highlight, underline, and take colorful notes with a stylus, and are willing to sacrifice some battery life, a color display might be more suitable for you.
5. Backlight and Color Temperature Adjustment
Built-in backlight provides sufficient illumination in low-light environments and reduces eye fatigue. Color temperature adjustment allows you to adjust the light color based on ambient lighting, with white light suitable for daytime reading and yellow light more suitable for nighttime use.
6. Storage Capacity
Most e-book readers come with 8GB, 16GB, or 32GB of storage, which is sufficient for storing thousands of e-books. Some models support memory card expansion or have cloud storage capabilities, allowing users to store more content without occupying the built-in storage.
7. Physical Page-Turning Buttons
o Physical Buttons: Convenient for page-turning without moving your fingers, suitable for extended reading sessions.
o Touchscreen: Intuitive operation, but there is a possibility of accidentally turning pages by touching the screen.
8. Closed/ Open System
o Open System: Allows downloading of third-party applications, offering high flexibility but potential compatibility issues.
o Closed System: Can only use built-in platform applications, providing high stability and optimal display performance, suitable for users who prefer not to deal with technical issues.
9. Additional Features
o Audiobooks: Supports audio playback, convenient for users who enjoy listening to books.
o Digital Note-Taking: Supports stylus input, suitable for users who need to take notes while reading.
o Color Comic Reading: Displays color content, but usually comes at a higher price.
