据供应链消息，E Ink 原定今年亮相的新一代 Carta 1400 电子纸屏幕，量产时间可能要推迟到 2027 年下半年。E Ink 的几家核心代工伙伴——为亚马逊 Kindle 代工的富士康（Foxconn）、生产 Kobo 与 NOOK 的 Netronix，以及专注 B2B 市场的 Linfiny——都已经拿到了新屏幕技术的样品，用于评估未来电子书阅读器的适配方案。
目前 E Ink 官网甚至还没有 Carta 1300 的白皮书或产品页，而该技术已在中高端 Kindle、Kobo 阅读器上应用多年，官方也未披露 Carta 1400 具体会带来哪些升级。业界传闻称，新面板将把标准光学对比度推过 20:1，带来更锐利的文字；更低的延迟会让翻页、滚动和手写更接近 iPad 或真实纸笔的手感；更高的对比度则提供「更纯」的黑与更亮的白，最大化户外与弱光下的可读性；并通过精炼的波形技术大幅减少文字残影，以及整屏刷新时常见的「黑闪」现象。
回顾来看，Carta 1300 只是 Carta 1200 的代际渐进优化，而 Carta 1200 本身是一次从底层架构出发的大改，为电子纸行业带来了显著更快的刷新速度；Carta 1300 在同样的基础上，只带来了略好的对比度指标和更低的延迟。
Carta 1400 的延期还将产生连锁反应，波及尚处于原型阶段的 Kaleido 4 与 Gallery 4 彩色电子纸技术。这两类彩色方案只有等到 Carta 1400 先用于亚马逊 Kindle Paperwhite 等黑白电子纸阅读器之后，才会真正走向市场。换言之，在短期内，Kaleido 4 与 Gallery 4 这类彩色屏的问世节奏也会被一并拖慢。

According to supply chain sources, the new generation Carta 1400 e-paper screen, originally scheduled to debut this year by E Ink, may see its mass production delayed until the second half of 2027. Several core E Ink contract manufacturers — including Foxconn, which makes Amazon Kindles; Netronix, which produces Kobo and NOOK; and Linfiny, specializing in B2B markets — have already received samples of the new screen technology to evaluate compatibility for future e-book reader designs.
Currently, E Ink’s official website does not even feature a white paper or product page for Carta 1300, despite it having been used in high-end Kindle and Kobo readers for years. The company has also not disclosed what specific upgrades Carta 1400 will bring. Industry rumors suggest the new panel will push standard optical contrast beyond 20:1, resulting in sharper text; lower latency that should allow flipping, scrolling, and handwriting to feel more like an iPad or real pen on paper; higher contrast for “purer” blacks and brighter whites, maximizing readability in outdoor and low-light conditions; and refined waveform techniques to significantly reduce ghosting artifacts and the “black flash” often seen during full-screen refreshes.
Looking back, Carta 1300 was merely a generational refinement of Carta 1200, while Carta 1200 itself represented a major overhaul from the ground up, delivering significantly faster refresh rates across the e-paper industry. Carta 1300 built on that foundation with only slightly improved contrast and lower latency.
The delay of Carta 1400 will have cascading effects, impacting the still-prototypical Kaleido 4 and Gallery 4 color e-paper technologies. These colorful alternatives will not enter the market until Carta 1400 is first deployed in black-and-white readers like the Amazon Kindle Paperwhite. In short, the launch timeline for Kaleido 4 and Gallery 4 colored screens will also be pushed back in the near term.
