研制了一种简单实用的WO_3电改变色显示的驱动方式,并新设计了几个与显示电极面积相等或者2倍于显示电极面积的辅助电极。两种电极都用WO_3膜。预先让所有显示电极处于着色状态,而将想擦除的电极电荷移向辅助电极。没有增加麻烦的校整回路,也能够抑制由显示颜色不均匀所引起的显示质量恶化。
A simple and practical WO 3 electrochromic display driver was developed and several auxiliary electrodes were newly designed with the same or two times of the display electrode area. Both electrodes use WO_3 membrane. All the display electrodes are colored in advance, and the electrode charges to be erased are moved toward the auxiliary electrodes. The adjustment loop without additional troubles can also suppress the deterioration of the display quality caused by the uneven display color.
