電泳式電子墨水(Electrophoretic Ink)

電泳式電子墨水(Electrophoretic Ink)技術通稱為電子墨水(Electronic Ink)。將電子墨水塗佈在一層塑膠薄膜上,再貼覆上薄膜電晶體(TFT)電路,經由驅動IC控制,形成像素圖形,創造了電子紙顯示器(Electronic Paper Displays, EPD),也常被習稱為電子墨水螢幕、電子墨水屏等,具體而微地形容了這是一塊用墨水、也像墨水製造出的螢幕。




電子墨水由數百萬個微膠囊(Microcapsules)所構成,微膠囊的大小約等同於人類頭髮的直徑。每個微膠囊裡含有電泳粒子懸浮於透明液體中,使用一種黑色電泳粒子的系統,創造出E Ink JustTint™。

E Ink JustTint™利用較新的電壓驅動方式,將黑色墨水移動至兩側,中間形成透明的通道,從上方看下來就是透明的。經由控制黑色墨水的分布,可以控制電子墨水薄膜從透明到不透明的通透度。

將E Ink JustTint™電子墨水薄膜貼覆至玻璃或塑膠上,可以控制光的透射程度。

  • What is E Ink?

    E Ink is the creator of electronic ink — the optical component of a film used in Electronic Paper Displays. Although futuristic-sounding, electronic ink is actually a straightforward fusion of existing knowledge of chemistry, physics and electronics to create this new material. It's so much like paper, it actually utilizes the same pigments used in the printing industry today.

    While E Ink has several types of electronic ink, we became best known for our microcapsule technology. In this system, the electronic ink is made up of millions of tiny microcapsules, about the diameter of a human hair. Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the user. This makes the surface appear white or black at that spot.

  • Does E Ink have a color product or is it only monochrome?

    E Ink has several color products available.

    E Ink also offers a three to five color product called E Ink Spectra, which is optimized for electronic shelf labels and point-of-purchase sale applications.

    In addition, E Ink offers a one-color product called E Ink Prism, which is optimized for the Architecture market.

    For full color, we have E Ink Gallery; and E Ink Kaleido in 4096 colors.

  • How long does it take to update an image on an E Ink Matrix display?

    An E Ink display module supports numerous modes for updating the display. Different modes exist to support the different update requirements. Update times can be as short as 120 ms. for the entire display. However, because E Ink screens are bi-stable, only the regions of the screen that are changing require updating. Any pixels that are not changing do not require updating.

  • Can an E Ink Matrix display support animation or video rates?

    Using the faster update modes, E Ink screens can support animation quality video rates. A number of examples are available from customers that show examples of E Ink screens showing video. However, constant updates reduce the power efficiency of our ink systems. Current production modules do not support video rate updates.
