Fabrication of Novel Emissive- and Reflective-Selectable Dual Mode Display

我们制作了一种新型的电化学反应驱动的双模显示器。我们使用电致变色(EC)和电化学发光(ECL)分别作为DMD单元的反射和发射模式。我们的DMD单元在直流偏压作用下表现为反射模式的EC特性，在交流偏压作用下表现为发射模式的ECL特性。我们首次合成了以邻苯二甲酸酯或聚(3，4-乙二氧基噻吩基)(PEDOT)为电致发光材料，以Ru(Bpy)_3为电致发光材料的DMD。结果表明，DMD在直流电压作用下发生颜色变化，在交流电压作用下发生发射。

We fabricated novel dual-mode display (DMD) driven by electrochemical reaction. We employ electrochromism (EC) and electrochemiluminescent (ECL) as reflective and emissive mode in DMD cell, respectively. Our DMD cell shows EC properties as reflective mode under DC bias application and ECL properties as emissive mode under AC bias application. We first fabricated the DMD which has phthalate derivatives or poly (3,4- ethylene dioxythiophene) (PEDOT) as EC material and Ru(bpy)_3 complex as ECL material. It is revealed that the DMD shows color change under the application of DC voltage and emission under the application of AC voltage.
