The invention provides a magnetic panel (2) and a magnetic display assembly incorporating such panel (2). The panel (2) comprises a front sheet (6) and a rear sheet (8) of non-magnetic material between which is a chamber including a plurality of pockets (12), the pockets (12) containing a fluid mix (14) consisting of a magnetic coloured pigment, a hydrocarbon fluid or its oxygenated derivatives or an aqueous solution, a surface active dispersing agent and a pseudo-plastic thickening agent. A magnetic stylus is used to cause the magnetic coloured pigment, in the form of magnetic parti- ' cles, to moved through the fluid mix (14).
The panel (2) may form part of a magnetic display assembly which includes a top and a base, the top being hingedly secured to the base so that the top may move relative to the base, the panel being incorporated in the top of the assembly.
本发明提供了一种磁性面板(2)和包含这种面板(2)的磁性显示组件。面板(2)包括非磁性材料的前板(6)和后板(8),前板(6)和后板(8)之间是一个包括多个口袋(12)的腔室,口袋(12)中装有混合液(14),混合液(14)包括磁性彩色颜料、烃类流体或其含氧衍生物或水溶液、表面活性分散剂和假塑性增稠剂。使用磁性触针使磁性彩色颜料以磁性颗粒的形式在混合液 (14) 中移动。
面板 (2) 可构成磁性显示组件的一部分,该组件包括顶部和底座,顶部与底座铰接固定,从而使顶部可相对于底座移动,面板与组件的顶部相连。
