| 摘要 |
This invention generally relates to electronic displays, in particular organic light emitting diode (OLED) -based displays, and to techniques for compensating for variations in display element brightness such as those caused by ageing. A method of compensating for variations in brightness of an OLED display element of a passive OLED display device, the display device having a plurality of said OLED display elements mounted on a substrate, the method comprising: driving a said display element to emit light; detecting a brightness said emitted light after waveguiding by said substrate; and compensating for a variation in said display element brightness responsive to said detecting. |
