Disassembly of Consumer Tablets: A Comparison from LCD to E-Ink Screens

Tablets, when mentioned, often conjure images of vibrant LCD or OLED screen devices. However, with technological advancements, a new type of tablet—the e-ink tablet—has gradually entered the public eye. This article will dissect the internal world of consumer tablets, including traditional tablets and the emerging e-ink tablets, exploring the true core elements and aesthetic aspects of the products.

1. Internal Components of Tablets: Differences Between Traditional Tablets and E-Ink Screens

Opening a traditional tablet (taking the Xiaomi tablet as an example), we find that its internal structure mainly includes the following components:

Battery: Typically a lithium polymer battery, with a capacity of around 6520mAh, occupying the largest internal space.

Mainboard: The “brain” of the tablet, featuring a single mainboard design that integrates the processor, memory, flash storage, and other core components.

Display: Traditional tablets mostly use LCD or OLED screens, while e-ink tablets utilize electronic ink screens. Electronic ink screens consist of numerous microcapsules, each containing positively charged white particles and negatively charged black particles, displaying content through changes in the electric field.

Camera: Usually a combination of front and rear cameras.

Shell and Fixing Structure: Most tablets adopt a unibody design, secured with clips and screws.

Speaker Module: Responsible for sound output from the device.

Interface Module: Includes USB ports, 3.5mm headphone jacks, etc.

The internal structure of e-ink tablets is similar to that of traditional tablets, but their core technology—the electronic ink screen—has fundamental differences. The electronic ink screen relies on ambient light reflection rather than backlight emission, providing a display effect that is closer to paper. This is also a significant reason why e-ink devices are moreeye-friendly.

2. Differences Among Brands: Comparison of Traditional Tablets and E-Ink Screens

Different brands of tablets exhibit significant differences in design and performance, with e-ink tablets and traditional tablets each having their own focus:

Traditional Tablet Brands:

Huawei Tablet: Focuses on productivity and AI features, such as the MatePad series equipped with high-performance processors and quality screens, supporting multi-screen collaboration.

Apple iPad: A well-established ecosystem, featuring M-series or A-series chips, strong performance, and a complete ecosystem with dedicated accessories.

Xiaomi Tablet: Offers good value for money, using Snapdragon series processors and high refresh rate screens, but third-party app compatibility needs improvement.

Lenovo Tablet: Emphasizes practical features, supports storage expansion, suitable for student groups.

E-Ink Tablet Brands:

Hanwang: An experienced manufacturer of e-ink readers, with notable achievements in technology development and a very stable system. The Hanwang N10 features a large 6000mAh battery and an open operating system that allows downloading common apps.

Huawei E-Ink Tablet: Very reliable in hardware configuration and product quality control. The Huawei MatePad Paper features the world’s first e-ink screen certified by the German Rhine for paper-like display, greatly restoring the texture of paper books.

Wenstone E-Ink Tablet: With over a decade of R&D experience in e-ink readers, offering a full range of product models, focusing on business and professional fields. The Wenstone NoteX3 supports various split-screen modes, significantly enhancing learning and work efficiency.

iFlytek Smart Office Book: Occupies a niche in the market with its excellent voice-to-text capabilities, accurate handwriting recognition, and stylish design. It is undoubtedly an ideal choice for users seeking efficient recording and organization.

Remarkable: Known for its 10.3-inch e-ink screen and near-paper writing experience, it has received widespread acclaim. Its low latency and high fluidity in handwriting make it a favorite among handwritten note enthusiasts.

Zhiyue Smart4 Pro: A leading Chinese digital reading brand with a vast array of reading resources and significant advantages in book copyrights. It features the self-developed book city app, which contains hundreds of thousands of certified genuine books.

3. What is Decoration, and What are the True Core Elements

True Core Elements:

1. Processor Performance: Whether traditional or e-ink tablets, the processor is the “heart” of the device. Low-end processors can lead to lag during use, affecting the experience.

2. Screen Quality: For traditional tablets, it is important to choose screens with high resolution, wide color gamut, and high brightness. For e-ink tablets, PPI (pixels per inch) and grayscale parameters are key. The higher the grayscale level, the more delicate the display effect.

3. Actual Battery Life: It is recommended to choose a tablet with an appropriate battery capacity based on usage needs. E-ink tablets typically have much longer battery life due to their different working principles.

4. System Compatibility: If you already have a smartphone or computer of the same brand, choosing a tablet from the same brand will greatly enhance the interconnectivity experience between devices.

5. Stylus Performance: When selecting a stylus, pay attention to latency performance. High latency can make drawing and note-taking less smooth.

6. System Openness: E-ink tablets can be divided into open and closed systems. Open systems allow for the installation of software but require higher performance from the device; closed systems are simple and stable but have limited functionality.

7. Eye Protection Features: E-ink tablets, due to their reflective principle, have no blue light and no flicker, making them more eye-friendly compared to traditional tablets.

Secondary but Not Major Elements:

1. Overhyped “AI Features”: Some low-end tablets advertise AI features that are essentially meaningless and provide little value in actual use.

2. Memory Fusion Technology: Some products claim large memory through memory fusion technology, but actual performance does not improve.

3. Blind Pursuit of “Productivity” : Tablets cannot completely replace computers. If the sole purpose is for office work, careful selection is necessary, considering actual needs.

4. High-Pixel Cameras: The cameras on tablets are mainly used for video calls and document scanning, so there is no need to pursue high pixels excessively.

5. Overhyped Color E-Ink Screens: Currently, color e-ink screen technology is not fully mature, usually with lower PPI and display effects inferior to black-and-white e-ink screens, yet priced higher. Unless there is a specific need for color, such as reading color comics, it is not advisable to blindly choose color versions.

6. Unnecessary Thin and Light Design: Overemphasis on thinness may sacrifice battery capacity or structural strength, affecting the actual user experience.

Conclusion

Through disassembly and analysis, although traditional tablets and e-ink tablets are both called “tablets,” their positioning and applicable scenarios are quite different. Traditional tablets are more suitable for entertainment, creation, and productivity scenarios, while e-ink tablets focus on reading, note-taking, and eye protection needs.

A worthwhile tablet should possess good processor performance, high-quality screens, sufficient battery life, and comprehensive ecosystem support. Compared to those flashy but impractical features, thesecore elements are what truly enhance the user experience.
