    摘要: The presently described embodiments comprise a system that includes a color changing medium, an erasing device using heat or long wavelength infrared light as the erasing source, a writing device that can imagewise apply a UV light to write the image on the media, and a transport to transport the media along a paper path to be seen by the erasing device and the writing device. The system could also function in an alternative way. The image could be “erased” to the all dark state using light (e.g. ultraviolet light) and then heated or illuminated using, for example, infrared light in imagewise fashion to produce the image.

    摘要: A reimagable medium and a method for “writing” to a reimagable medium are disclosed. The reimagable medium includes a liquid crystal layer, one or more photochromic layers and an electric field generating apparatus. The electric field generating apparatus supplies voltage levels across the liquid crystal layer causing the liquid crystal layer to transfer between a white and a transparent state. The photochromic layers transfer to a colored state when illuminated by ultraviolet light and to a transparent state when illuminated by visible light. Each of the layers maintains their present states when voltage or illumination below corresponding thresholds is supplied. The reimagable medium is flexible and may maintain an image “written” to it until the paper is rewritten. The paper may be attached to a colored substrate if an additional color is to be displayed.

    摘要翻译: 公开了一种用于“写入”到可重复介质的可重​​复介质和方法。 可重复介质包括液晶层,一个或多个光致变色层和电场产生装置。 电场产生装置提供跨越液晶层的电压电平,使液晶层在白色和透明状态之间传输。 当被紫外线照射时,光致变色层转移到有色状态,当被可见光照亮时,其变成透明状态。 当提供低于相应阈值的电压或照明时,每个层保持其当前状态。 可重复使用的介质是灵活的,并且可以保持图像“写入”直到纸被重写。 如果要显示额外的颜色,纸张可以附着到有色基底上。
