Daylight Computer – New 60fps e-paper tablet

Original Article ↗ Hacker News Discussion ↗

A startup has launched the Daylight DC-1, a $729 Android tablet built around a custom monochrome “LivePaper” transflective LCD that aims to combine e‑ink‑like readability and low eye strain with 60–120 fps refresh, pen input and general‑purpose computing. Enthusiasts are excited about the prospect of coding, reading and note‑taking outdoors, the promise of an unlockable bootloader, and future devices like monitors, laptops and phones based on the same display tech. Skeptics question the high price, middling CPU, lower DPI, marketing claims around “e‑paper” and blue light, and whether a small hardware company can deliver long-term software updates, transparency and wider availability.

Display technology & image quality

  • Not traditional E‑Ink; it’s a custom monochrome reflective / transflective LCD branded “LivePaper.”
  • Uses IGZO, variable refresh (6–120 Hz). Marketed at 60 fps; company says panel can do 120 but software isn’t there yet.
  • 190 PPI, 256 grayscale levels, no color. Chosen to increase brightness via larger aperture rather than higher DPI.
  • Uses a backlight shining through micro‑perforations in the reflective layer (not a frontlight), aiming for better contrast and unchanged pen feel.
  • Not bistable: unlike E‑Ink, it needs power to maintain an image.
  • Some users worry about lower contrast vs paper / E‑Ink and about backlight bleed in early videos; company says current production units are improved.
  • Comparisons made to Pebble, OLPC, old Palm/Sharp MIP/transflective displays, and recent RLCD monitors.

Hardware, OS & openness

  • Android 13 on a MediaTek Helio G99 (midrange SoC), 8 GB RAM, 8000 mAh battery, microSD, Wacom EMR pen, extra mappable buttons, pogo pins.
  • No LTE in v1 (cost and certification); no mention of headphone jack in the thread.
  • Custom “Sol:OS” is essentially Android with a different launcher and “calm” defaults (e.g., notifications off, potential app‑delay features).
  • Bootloader unlock tool is promised so users can flash LineageOS or other ROMs; interest in mainline Linux/postmarketOS; company is open but unsure of resources.
  • Some want full open‑sourcing of drivers/firmware; others say an unlockable bootloader may be sufficient.

Performance, battery & use cases

  • Early testers report smooth scrolling, PDF zoom, and handwriting, with low ghosting; coding, SSH, terminal, VS Code (remote) and Obsidian seen as viable.
  • Example tests: ~67h reading without backlight, ~30h YouTube or reading with some backlight; one engineer reports charging every ~2 weeks with 1–2h/day.
  • Tradeoff vs E‑Ink: worse standby life but much higher responsiveness.

Price, positioning & future products

  • Price around $729–$800 (includes stylus and some accessories). Many see it as expensive vs iPads, Boox, Supernote; others argue it’s fair for first‑gen, low‑volume custom hardware.
  • Strong demand for: external “dumb” monitor version, larger (A4/13") panels, laptop, phone, and Pebble‑style watch using this tech.
  • Full refund if users don’t like it; shipping currently limited to select countries, frustrating some.

Website, marketing & trust

  • Heavy, scroll‑hijacking site widely criticized; some devices crash or stutter on it.
  • Confusion and backlash over initial “e‑ink/e‑paper” framing and one sped‑up demo video; others point to real‑time videos and upcoming third‑party reviews.
  • “Blue‑light free” messaging and lack of clear specs/company info on the main page draw skepticism.
