A system and method for compensating for non-uniform illumination from a light guide for a display in an electronics device is provided. A polarized light wavelength characteristic changing element has a wavelength characteristic such that the transmittances or reflectances of P- and S-polarized rays vary differently with respect to wavelength. Each magnetic pole has a primary magnet and two auxiliary magnets disposed on respective sides of the primary magnet. A cell library cell that can automatically avoid forbidden pitches is provided.
