电色显示(Electrochromic display)(缩写ECD)是由于电化学反应所引起物质颜色的变化。这种显示具有视角宽,工作电压低(0.4～1.5伏),功耗稍大于液晶显示,能存储,亮度高,工作温度宽,可制成任何形状的平板显示等优点。根据显示物理、化学原理的不同,电色显示大体上可区分为表1中所列的二种类型~([1][2][3])。一、几种电色显示器简介 1.以WO_3为基础的ECD器件器件的基本结构如图1所示。即在玻璃基片上镀一层透明导电层(SnO_2或In_2O_3膜),光刻成图形后,蒸发或溅射约0.3～1.5μm的无定形WO_3(三氧化钨)薄膜,(可采用热蒸发,电子枪蒸发,反应或非反应溅射与喷涂等方法)。反电极 Electrochromic display (abbreviated ECD) is a change in the color of a substance caused by an electrochemical reaction. This display with wide viewing angle, low operating voltage (0.4 ~ 1.5 V), power consumption slightly larger than the liquid crystal display, can store, high brightness, wide operating temperature, can be made into any shape of the flat panel display and so on. According to the display of physical and chemical different, electrochromic display can be roughly divided into the two types listed in Table 1 ~ ([1] [2] [3]). First, several kinds of color display Brief introduction 1 to WO_3-based ECD device The basic structure of the device shown in Figure 1. That is, a transparent conductive layer (SnO 2 or In 2 O 3 film) is plated on a glass substrate, and an amorphous WO 3 (tungsten trioxide) film with a thickness of about 0.3-1.5 μm is evaporated or sputtered after being patterned by photolithography, Electron gun evaporation, reactive or non-reactive sputtering and spraying methods).
