| 摘要 |
An electro-optical unit (1) is used as a picture element and is provided with a photodiode (2) and a light-emitting diode (3), each having a first and a second electrode (2a, 2c, 3a, 3c), as well as a programmable resistive memory element (4) having a first and a second terminal (4a, 4b). The electro-optical unit further has first, second and third control terminals (12, 13, 14) wherein the photodiode (2) and the programmable resistive memory element (4) are coupled in series between the first control terminal (12) and the third control terminal (14), and wherein the light-emitting diode (3) and the programmable resistive memory element (4) are coupled in series between the second control terminal (13) and the third control terminal (14). An array of electro-optical devices is also provided to form a display device comprising a plurality of electro-optical units (1) having their first control terminal (12), second control terminal (13) and third control terminal (14) respectively coupled to a common first control line, a common second control line and a common third control line. |
