Rohm certainly has a thing for cranking out diminutive devices that elicit attention, and the firm chose CEATEC as the venue to demonstrate its long-awaited full-color OLED that's "smaller than a fingernail." According to a company spokesperson, the 320 x 240 resolution display measures around four- by three-millimeters, is "embedded in a prototype chip and is designed for use in a video-camera viewfinder." Notably, the unit actually requires humans to view it under a microscope in order for it to be clearly seen, and although nothing was said about a commercialization date, it was suggested that Rohm is already working up a similar version with twice the pixels.
