摘要
电容触摸屏存在表面反射率高、眩光、辐射能量高和易受干扰等缺点,这阻碍了电容触摸屏在高端显示器上的应用。研究发现,对电容触摸屏表面玻璃进行AR和AG处理,并配合使用圆偏光片,可以将反射率由6.8%降至0.85%,同时实现防眩光效果;且通过对电容触摸屏进行屏蔽、接地和参数调整,能有效降低其辐射发射能量,并提高抗干扰能力。
Abstract
Capacitive touch panel(CTP) has disadvantages, such as high surface reflectivity,glare,high radiant energy and vulnerability to interference,which could hinder the application of the CTP on high-end displays. In this paper,it is found that AR and AG processing on CTP surface and using circular polarizers could reduce the reflectivity from 6.8% to 0.85%, and could simultaneously achieve anti-glare. And by shielding and grounding the CTP, together with parameter adjustment,the radiation emission energy could be effectively reduced and the anti-interference ability could be improved.
