发明名称 Active matrix pixel brightness control
摘要 A multiple pixel display and method of driving same. Each pixel (300) in the display (202 has a light emitting element (324) and a drive current controller (322). A control terminal of the drive current controller (340) receives an intensity control input and drives the light emitting element with an amount of electrical current based upon the intensity control input. Each pixel also has a voltage storage device (320) that is charged with a programmed voltage between with a first terminal that is electrically coupled to the control terminal, and a second terminal that is electrically opposite the first terminal of the voltage storage device. An intensity reduction input (306) of each pixel is electrically coupled to the second terminal of the voltage storage device and to respective intensity reduction inputs of other pixels within the plurality of pixels.
