Key challenges include handling screen refresh ghosting, avoiding scrolling in favor of pagination, buffering streaming LLM output to avoid constant redraws, and designing a high-contrast greyscale UI using layout and typography alone. The developer plans to build a Lemmy frontend and an OpenRouter frontend optimized for e-ink, to be released under the GPL. Community advice suggests treating e-ink more like print media than a slow computer screen, avoiding animations and transitions, preloading content before painting, and preferring filling white areas with black rather than the reverse. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How should I handle screen refreshes when building a web UI for an e-ink display? Treat refresh behavior like print or a moving newspaper rather than like a typical computer screen, and never assume anything will refresh on demand. Avoid animations and transitions entirely, preload content into fixed white areas ahead of time, then fill them in with black, since this works better than filling black-to-white in reverse. For long-running processes, push them behind a second page load instead of trying to update in place. _Anyone building e-ink interfaces can compare refresh-handling tricks like this through daily.dev._ ### What is the best way to display streaming LLM output on an e-ink screen? Streaming text token-by-token is considered close to a worst-case scenario for e-ink because of ghosting and refresh limitations, so output should be buffered and painted to the screen in chunks rather than updated continuously. This avoids the visual noise and slow, flickering redraws that come from treating an e-ink panel like a standard low-latency display. _Developers wiring LLM output into unusual displays can track UI patterns like this via daily.dev._ ## Similar posts on daily.dev - [Coding on Paper](https://daily.dev/posts/coding-on-paper-jcfcpkzfc) · Lobsters · 45 upvotes · 6 comments - [E Ink monitors are the productivity upgrade nobody's talking about, and it's high time for that to change](https://daily.dev/posts/e-ink-monitors-are-the-productivity-upgrade-nobody-s-talking-about-and-it-s-high-time-for-that-to-c-v6cazxeco) · XDA Developers · 1 upvotes · 0 comments - [An EInk, ESP32-based Game Boy](https://daily.dev/posts/an-eink-esp32-based-game-boy-gvqvablqq) · Hackaday · 0 upvotes · 0 comments - [I finally found the e-ink monitor I've been waiting for, and it changes how I work](https://daily.dev/posts/i-finally-found-the-e-ink-monitor-i-ve-been-waiting-for-and-it-changes-how-i-work-t2r3fhsds) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#webdev](https://daily.dev/tags/webdev), [#hardware](https://daily.dev/tags/hardware), [#frontend](https://daily.dev/tags/frontend), [#ui-design](https://daily.dev/tags/ui-design) [View this post on daily.dev](https://daily.dev/posts/ask-hn-in-your-experience-what-are-sound-conventions-for-e-ink-ui-development--magn6xjre) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Ask HN: In your experience, what are sound conventions for e-ink UI development?","url":"https://daily.dev/posts/ask-hn-in-your-experience-what-are-sound-conventions-for-e-ink-ui-development--magn6xjre","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/ask-hn-in-your-experience-what-are-sound-conventions-for-e-ink-ui-development--magn6xjre"},"datePublished":"2026-08-10T18:19:04.532Z","dateModified":"2026-09-14T06:04:32.904Z","description":"A developer switching to a black-and-white e-ink smartphone (Bigme Hibreak Pro BW) is seeking practical advice on browser-based frontend development for e-ink...","image":"https://media.daily.dev/image/upload/s--CxzD6vbw--/f_auto/v1722860399/public/Placeholder%2005","thumbnailUrl":"https://media.daily.dev/image/upload/s--CxzD6vbw--/f_auto/v1722860399/public/Placeholder%2005","isAccessibleForFree":true,"articleSection":"Hacker News","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Hacker News","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/hn","url":"https://daily.dev/sources/hn"},"commentCount":1,"discussionUrl":"https://daily.dev/posts/ask-hn-in-your-experience-what-are-sound-conventions-for-e-ink-ui-development--magn6xjre","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":3},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":1}],"keywords":"webdev,hardware,frontend,ui-design","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Hacker News","item":"https://daily.dev/sources/hn"},{"@type":"ListItem","position":3,"name":"Ask HN: In your experience, what are sound conventions for e-ink UI development?"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/ask-hn-in-your-experience-what-are-sound-conventions-for-e-ink-ui-development--magn6xjre#faq","mainEntity":[{"@type":"Question","name":"How should I handle screen refreshes when building a web UI for an e-ink display?","acceptedAnswer":{"@type":"Answer","text":"Treat refresh behavior like print or a moving newspaper rather than like a typical computer screen, and never assume anything will refresh on demand.
