Patent number: 8659584Abstract: In a display apparatus including a switching transistor, a correction voltage for eliminating an effect of a variation in a characteristic of a driving transistor is stored in a storage capacitor. The switching transistor is disposed between one current terminal of the driving transistor and a light emitting element. The switching transistor turns off during the non-light emission period thereby to electrically disconnect the light emitting element from the one current terminal of the driving transistor thereby preventing a leakage current from flowing through the light emitting element during the period in which the correction unit operates, and thus preventing the correction voltage from having an error due to the leakage current.Type: GrantFiled: December 17, 2012Date of Patent: February 25, 2014Assignee: Sony CorporationInventors: Junichi Yamashita, Masatsugu Tomida, Katsuhide Uchino

Patent number: 8654037Abstract: A functional, primary display means comprises a number of first, small pixel elements and comprises or communicates with image generating means for generation of a high resolution miniature image. A main display means comprises a dielectric material which is transparent to radio-, and/or millimeter waves and/or microwaves and comprises a number of second, passive, pixel elements substantially corresponding to, and considerably larger than, the first pixel elements. Each first pixel element is connected to a second pixel element by an optical transmission means for transfer of optical image information. The main display means is adapted to visually represent the transferred optical information as an enlarged image and receiving/transmitting means for communication of radio-, millimeter wave or microwave signals are arranged in or on the main display means such that reception/transmission can take place substantially independently of the optical representation.Type: GrantFiled: December 6, 2007Date of Patent: February 18, 2014Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Fredrik Harrysson, Jonas Medbo
