Modeling of microdisplay with movable membrane in MOEMS technology

Polymer display based on a movable membrane designed in MOEMS technology may be an alternative for other display devices. The display consists of two plastic elements. The first one is a planar waveguide. It is coated in metal with electric contacts etched in it. The second element is a metalized membrane with a matrix of pillars functioning as pixels. The simplicity of the setup makes it cheap and easy for mass production. On the other hand, each size of the display has to be optimized independently, which may be a problem. When deciding on the size of the matrix one has to optimize several interconnected parameters, which decide on the functioning of the display. In this paper we describe the modeling process for a 20×20 pixel matrix with an active display matrix area of 5×5 mm 2 .
