If you are searching for a refreshable braille display with 40 cells, the Brailliant BI 40X is the direct match in this comparison: its longer line shows more text at once, which can make reading and editing easier. I also include the Brailliant BI 20X because it offers the same family of onboard tools and multi-device approach in a more portable 20-cell format. The decision is not simply about choosing the larger display: the BI 40X favors broader braille context, while the BI 20X is easier to carry and may suit buyers who value mobility over line length. Both list up to 20 hours of battery life, but your screen reader needs, device setup, and intended reading habits should shape the final choice.

Brailliant BI 40X Braille Display
The Brailliant BI 40X is my first pick because it directly meets the defining requirement: 40 refreshable cells. A longer line can show more of a sentence or document before the user needs to move the display, making it a stronger fit for extended reading, editing, and screen-reader navigation than the BI 20X. That difference is the reason to select this model—not simply the larger number on its specification sheet.
Its Bluetooth 5 and USB-C connection options provide a choice between wireless use and a wired connection. The listing names JAWS, NVDA, Dolphin SuperNova, and VoiceOver, giving prospective buyers concrete compatibility points to verify against their own device and software versions. The BI 40X also has 32GB of internal storage, compared with 16GB on the BI 20X, plus KeySoft Lite applications, online library access, DAISY support, and text-to-speech. Together, these features make it the more capable choice for someone who wants a larger braille line and onboard reading tools.
The tradeoff is straightforward: a 40-cell unit is a less portability-led choice than the 20-cell BI 20X, and the supplied description identifies high cost and familiarity with braille technology and screen readers as barriers. The two models list the same battery life of up to 20 hours, so the BI 40X does not claim an endurance advantage to offset its larger format. I would choose it for line length and storage, not on the assumption that setup will be effortless or that every desired workflow is supported automatically.
Compared with the BI 20X, this model is better for readers who regularly work through longer passages and want more text available on the display at once. The BI 20X remains the sensible alternative for a buyer whose daily routine involves frequent travel or who does not need 40 cells. If you specifically want a 40-cell refreshable display, however, the BI 40X is the clear match in this pair.
Pros:- 40-cell display provides a longer braille line than the BI 20X.
- Bluetooth 5 and USB-C support wireless and wired connections.
- 32GB internal storage exceeds the BI 20X’s listed 16GB.
- Includes KeySoft Lite, online library access, DAISY support, and text-to-speech.
Cons:- The product information identifies high cost as a possible barrier.
- Users need familiarity with braille technology and screen-reader setup.
- The listed battery life is up to 20 hours, the same stated figure as the smaller BI 20X.
Best for: Braille readers and screen-reader users who want a 40-cell line for longer reading, document work, and supported onboard applications.
Not ideal for: Buyers who prioritize a more compact 20-cell format, need a very simple setup, or have not confirmed compatibility with their devices and screen-reader software.
- Display cells:40
- Connectivity:Bluetooth 5, USB-C
- Internal storage:32GB
- Battery life:Up to 20 hours
- Supported screen readers:JAWS, NVDA, Dolphin SuperNova, VoiceOver
- Onboard features:KeySoft Lite applications, online library access, DAISY support, text-to-speech
Our verdict“I recommend the BI 40X when a genuine 40-cell line and expanded onboard storage matter more than choosing the more portable 20-cell option.”
Brailliant BI 20X Braille Display
The Brailliant BI 20X is the portability-led alternative, not a substitute for a 40-cell display. Its 20-cell line shows less text at once than the BI 40X, so users who read long passages or edit documents may need to move through text more frequently. I include it because some shoppers searching for a 40-cell display may find that a smaller unit better matches a travel-heavy routine or their preferred device size.
It still offers a substantial set of connected and onboard features. The listing specifies Bluetooth connections for up to five devices and USB-C, as well as KeySoft Lite apps, text-to-speech, Wi-Fi, SD card support, and access to Bookshare, NLS BARD, and NFB Newsline. That combination can appeal to readers who want access to books and note-taking tools in a compact unit. Its stated battery life is up to 20 hours, matching the BI 40X’s listed figure, while its 16GB internal storage is half the larger model’s stated capacity.
The main limitation is also the reason to skip it: it does not meet a strict 40-cell requirement. The supplied description also flags setup as potentially complex and notes that full functionality depends on compatible screen readers. Unlike the BI 40X listing, the information provided here does not name specific supported screen readers, so I would verify compatibility with the manufacturer or seller before relying on it for a particular setup. The many connection and onboard options add usefulness, but they do not remove the need to configure the device.
Compared with the BI 40X, the BI 20X makes more sense when a smaller display is a deliberate choice, rather than when a buyer simply wants the least expensive or simplest route to 40-cell reading. It is the better match for carrying around and using across several connected devices; the BI 40X wins on line length and internal storage. If seeing more text at once is the central reason for your search, I would choose the 40X instead.
Pros:- Compact 20-cell format is the more portability-focused option in this comparison.
- Bluetooth supports connections to up to five devices, alongside USB-C.
- KeySoft Lite, text-to-speech, Wi-Fi, and SD card support add onboard options.
- Lists access to Bookshare, NLS BARD, and NFB Newsline.
Cons:- Its 20-cell display does not satisfy a strict 40-cell requirement.
- 16GB internal storage is lower than the BI 40X’s 32GB.
- Setup may call for technical familiarity, and compatible screen readers are needed for full functionality.
Best for: Mobile readers who value a compact display, multi-device Bluetooth connections, and onboard library access more than a 40-cell line.
Not ideal for: Anyone whose requirement is specifically a 40-cell refreshable braille display, or who needs confirmed compatibility with a named screen reader before purchase.
- Display cells:20
- Connectivity:Bluetooth for up to five devices, USB-C
- Internal storage:16GB
- Battery life:Up to 20 hours
- Supported libraries:Bookshare, NLS BARD, NFB Newsline
- Onboard features:KeySoft Lite apps, text-to-speech, SD card support, Wi-Fi
Our verdict“I would pick the BI 20X only when compactness and multi-device use outweigh the need for the longer 40-cell line.”
How We Picked
I ranked these two displays against the specific search intent: a refreshable braille display with 40 cells. That makes the BI 40X the leading fit, because it has 40 cells; the BI 20X is included as a meaningful alternative for buyers who may accept fewer cells in exchange for a more portable design. I did not treat both models as interchangeable just because they share a product family.
I compared the supplied information across cell count, connectivity, onboard functions, storage, battery life, and stated compatibility. These details matter in daily use: cell count affects how much text appears at once, connectivity determines how the display can connect to devices, and onboard applications can support reading or note-taking without relying on a connected computer for every task. Storage capacity is a useful point of comparison, though the information provided does not specify how much space a typical library or file collection uses.
I also gave weight to practical limitations. The BI 20X description flags setup complexity and dependence on compatible screen readers for full functionality. The BI 40X likewise calls for familiarity with braille technology and screen readers, and its listed compatibility is useful but not a guarantee that every operating system, software version, or workflow will work without configuration. I have not assumed either model suits every user or treated stated battery life as a guarantee under all conditions. The ranking reflects fit for the requested 40-cell format, not a claim that the larger display is better for every buyer.
| refreshable braille display 40 cell | Connectivity | Onboard features |
|---|---|---|
| Brailliant BI 40X Braille Disp | Bluetooth 5, USB-C | KeySoft Lite applications, online library access, DAISY support, text-to-speech |
| Brailliant BI 20X Braille Disp | Bluetooth for up to five devices, USB-C | KeySoft Lite apps, text-to-speech, SD card support, Wi-Fi |
Factors to Consider When Choosing Refreshable Braille Display 40 Cell
For this comparison, the key choice is whether you need a 40-cell display itself or are willing to trade line length for a more portable 20-cell unit. I would settle that first, then check the connection and software details that determine whether the display will fit your everyday setup.
Start with the cell count you actually need
A refreshable braille display’s cell count affects how much text appears on its line at once. The BI 40X shows twice as many cells as the BI 20X, so it is the more direct choice for reading longer text and moving through documents with fewer display advances. That does not make a 20-cell model unsuitable for reading, but it does make the user experience different. If your search specifically means you need 40 cells, the BI 20X is not an equivalent option; if you are still deciding on size, compare the value of a longer line against portability.
Check screen-reader and device compatibility
The BI 40X listing names JAWS, NVDA, Dolphin SuperNova, and VoiceOver. Use that list as a starting point and verify the exact operating system, screen-reader version, and connection method you intend to use. The BI 20X description says it needs compatible screen readers for full functionality but does not provide a named list in the supplied details. I would ask the seller or manufacturer to confirm support for your specific setup rather than assume that a device connection alone means every feature will work.
Compare connections around your routine
Both products specify Bluetooth and USB-C, allowing wireless use or a wired connection. The BI 20X states support for up to five Bluetooth devices, while the BI 40X specifies Bluetooth 5. If you regularly switch between a phone, computer, and tablet, confirm how device pairing and switching work in your preferred workflow. A wired connection may be useful when you want a direct link, but the listing does not detail cable behavior across every supported device, so verify that before purchase.
Match storage and onboard tools to your reading habits
The BI 40X lists 32GB of internal storage; the BI 20X lists 16GB and adds SD card support. The storage difference may matter if you expect to keep many books or files directly on the display, but the supplied information does not specify usable capacity or file limits. The BI 20X names Bookshare, NLS BARD, and NFB Newsline, while the BI 40X lists online library access and DAISY support. Check that the services and formats you rely on are supported for your region and intended way of reading.
Treat battery life as a stated maximum
Both models list up to 20 hours of battery life, so the provided specifications do not give either one an endurance advantage. Actual use can depend on settings, connection type, and which features are active. If you plan long days away from a charging point, ask how the unit performs under your typical use and consider your access to USB-C charging. I would not choose the BI 40X over the BI 20X on battery claims alone.
Plan for setup and support
The BI 20X description explicitly warns that setup may require technical familiarity; the BI 40X also assumes familiarity with braille technology and screen readers. Before buying, confirm what initial configuration help, documentation, and support are available, especially if this is your first refreshable display. The onboard apps can add independence, but they do not remove the need to learn controls or set up connections. Buyers who need an immediately simple experience should clarify the setup process before choosing either model.
Frequently Asked Questions
Which product in this comparison has 40 cells?
The Brailliant BI 40X is the 40-cell model. The Brailliant BI 20X has 20 cells, making it a smaller-format alternative rather than a match for a strict 40-cell requirement. If cell count is the deciding specification, the BI 40X is the direct choice.
Is the BI 20X a suitable alternative to the BI 40X?
It can be a suitable alternative if you prioritize a compact display and can work comfortably with a 20-cell line. It lists multi-device Bluetooth, USB-C, onboard apps, and library access, but it displays less text at once and has 16GB of internal storage rather than the BI 40X’s 32GB. I would not choose it as a substitute if 40 cells are mandatory.
Do both displays work with screen readers?
The BI 40X listing names JAWS, NVDA, Dolphin SuperNova, and VoiceOver. The BI 20X description says compatible screen readers are needed for full functionality but does not name specific products in the information provided. Compatibility can depend on your operating system and software version, so confirm your exact setup before purchasing either display.
How does battery life compare between the BI 20X and BI 40X?
Both listings state up to 20 hours of battery life, so the supplied specifications show no difference between them on this point. That figure is a stated maximum, not a guarantee for every use pattern. If long sessions away from charging are part of your routine, ask how battery performance varies with your likely connection and feature settings.
What should I verify before ordering a refreshable braille display?
Confirm the cell count, screen-reader and operating-system compatibility, connection method, and access to the library services or file formats you use. I would also check setup support and clarify how onboard storage and charging suit your routine. For these two models, the central choice is whether you need the BI 40X’s longer line or prefer the BI 20X’s more compact format.
Conclusion
For buyers who specifically want a refreshable braille display with 40 cells, I recommend the Brailliant BI 40X: its longer line and 32GB of internal storage make it the clear fit in this comparison. Choose the BI 20X if you are a mobile reader who values its compact 20-cell design, multi-device Bluetooth, and named library support more than seeing as much text at once. If neither cell count nor screen-reader compatibility is confirmed for your needs, pause to verify those details before ordering. My decision rule is simple: choose the 40X for a true 40-cell reading line, and the 20X only when portability is the priority.
