摘要

我们开发了一个电致变色体素阵列来实现三维(3D)显示。体素是三维图形数据的单位，就像二维数据的像素一样。体素的颜色不是通过它们的光发射来调节的，而是通过它们的光吸收来调节的，就像现实世界中事物的颜色一样。我们的体素由玻璃基板上的ITO电极和1毫米立方体的紫外线固化聚合物组成，该聚合物涂有电致变色材料，可以通过电改变其颜色。我们利用聚-(3,4-乙烯二氧基-噻吩):聚苯乙烯磺酸盐(PEDOT:PSS)作为电致变色材料。我们的体素阵列及其Al对电极浸泡在CaCl2溶液中。体素在约1.0 V的极低电压下操作，我们展示了4x4体素阵列，不仅在俯视图中观察到体素的颜色变化，而且在侧视图中也观察到体素的颜色变化。

Electrochromic voxel array for 3D display

We developed an electrochromic voxel array for realizing a three-dimensional (3D) display. A voxel is a unit of 3D graphic data just as a pixel of 2D data. The color of voxels is tuned not by their light emission but by their light absorption in the same way as the coloration of things in the real world. Our voxels consist of ITO electrodes on glass substrates and 1 mm cubes of an UV-curing polymer coated with electrochromic material which can change its color electrically. We utilized poly-(3,4-ethylenedioxy- thiophene):polystyrenesulfonate (PEDOT:PSS) as the electrochromic material. Our voxel array and its Al counter electrode were soaked in CaCl2 solution. Voxels were operated with a very low voltage of about 1.0 V We demonstrated a 4x4 voxel array, and the color change of the voxels was observed not only in the top view but also in the side view.
