An asymmetric whispering gallery mode resonator device is described. The resonator device includes an asymmetric whispering gallery mode resonator disk (e.g., transparent material, electrooptic material). The resonator disk includes an axial surface along a perimeter of the resonator disk, a top surface, and a bottom surface. A first midplane passes through the axial surface dividing the axial surface into symmetrical halves. The top surface and the bottom surface are substantially parallel, and a second midplane is substantially equidistant between the top surface and the bottom surface. The first midplane and the second midplane are non-coextensive. The asymmetric whispering gallery mode resonator disk can further include a first chamfered edge between the top surface and the axial surface, and a second chamfered edge between the bottom surface and the axial surface. Moreover, the resonator device includes a first electrode on the top surface and a second electrode on the bottom surface.

Disclosed herein is a display device for increasing the transmittance of R, G, and B sub-pixels and reducing a transmittance of W sub-pixel through a pixel asymmetric design. To this end, the display device has a pixel asymmetric structure in which W sub-pixel has a different area from R, G and B sub-pixels. As a result, as the display device has an asymmetric structure in which the areas of W, R, G, and B sub-pixels are different from one another, particularly, an asymmetric structure in which the area of W sub-pixel is reduced and the area of R sub-pixel is increased. Such design has a structural advantage that the transmittance of R, G, and B sub-pixels can be increased and the transmittance of W sub-pixel can be lowered so that it is possible to correspond the product specifications in various ways.

An overall displacement tolerance applicable to each pixel tile in a plurality of pixel tiles to be used as parts of an image rendering surface is determined. Each pixel tile in the plurality of pixel tiles comprises a plurality of sub-pixels. Random displacements are generated in each pixel tile in the plurality of pixel tiles based on the overall displacement tolerance. The plurality of image rendering tiles with the random displacements are combined into the image rendering surface.
