Abstract: This disclosure provides systems, methods and apparatus for a MEMS display apparatus incorporating a tiered backplane slot structure. The backplane can include two or more light-blocking layers defining optical windows and positioned at different heights. Light can pass through the optical windows of the display apparatus at an angle. In some implementations, the angle can be based on the index of refraction of a transparent material inside the display apparatus. The transmission of off-axis and on-axis light can be improved by varying the widths of the optical windows in each layer of the backplane. In some implementations, the difference in the widths of optical windows of adjacent layers can be substantially equal to the separation distance between the layers.
