    • A low cost, scalable backplane for black and white or color optical displays comprises a multi-membrane plastic structure on which is printed or deposited row and column drivers to form a matrix of micro electromechanical (MEM) switches. Each switch controls the state of a pixel in the optical display device. Critical to successful long-term operation, the backplane includes the controlled application of voltages to each switch so that the display functions correctly and display life is maximized. The MEM switches include a substantially non-pliable membrane and a substantially flexible membrane both of which include electrodes that when energized will create electrostatic forces that attracts the flexible membrane to the non-pliable membrane. The MEM switches are manufactured in an array with a pitch that provides a sufficient number of switches to drive an optical display device and each switch may be latched to eliminate the need to constantly refresh the device.
    • 用于黑白或彩色光学显示器的低成本,可扩展背板包括多膜塑料结构,印刷或沉积行和列驱动器以形成微机电(MEM)开关的矩阵。 每个开关控制光学显示装置中的像素的状态。 对于成功的长期运行至关重要,背板包括对每个开关的电压的受控应用,使显示器正常工作并显示寿命最大化。 MEM开关包括基本上不柔软的膜和基本上柔性的膜,两者都包括电极,其在被通电时将产生吸引柔性膜到非柔性膜的静电力。 MEM开关以阵列形式制造,具有提供足够数量的开关以驱动光学显示装置的间距,并且每个开关可被锁存以消除不断刷新装置的需要。
