A static random access memory comprising a plurality of SRAM cells, a plurality of wordlines and a voltage regulator for driving the wordlines with a wordline voltage signal. Embodiments of the invention provide the ability to design and create an application user interface that can be reliably and efficiently localized. Accordingly, the backup plate is resistant to deflection, and therefore deflection of the electro-optical panel can be effectively suppressed. A portion of this layer of material may be left intact on the scribe line areas during the manufacturing process. The washer nozzle performs a washing operation to wash a lens surface of the lens of the optical sensor or a glass surface of a cover glass located facing the lens by spraying a washer fluid, supplied from a washer fluid tank, onto the lens surface or the glass surface. Each coded tag encodes coordinates for a point on a tag map and an orientation feature.
