Micro-electromechanical switching backplane
InactiveUS20050116924A1Low costLow-cost techniqueElectrostatic/electro-adhesion relaysStatic indicating devicesDisplay deviceEngineering
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.
