Problems solved by technology

Likewise, as OLED efficiency decreases, the amount of current required to emit a given brightness increases over time
[0007] As the OLEDs in pixels on different regions of the display panel are driven differently, these OLEDs age or degrade differently at different rates, which can result in perceivable differences between pixels on a given display panel and non-uniformity

Embodiment Construction

[0037] The systems and methods disclosed herein can be used to detect and compensate for process or performance related non-uniformity and / or degradation in emissive displays. Systems disclosed herein compare a device (eg, pixel) current to one or more reference currents using one or more readout systems to generate an output signal representative of the difference between the device current and the reference current. The one or more readout systems described above may include one or more current integrators and / or current comparators, wherein each current integrator and / or current comparator uses a different circuit to generate an output signal. As will be explained in more detail below, the current comparators and current integrators disclosed herein each offer their own advantages and can be used to meet certain performance requirements. In some embodiments, the output signal is in the form of an output voltage. This output voltage can be amplified, and the amplified signa...

Abstract

The invention relates to a method for compensating for common unwanted signals present in pixel data measurements of pixel circuits in a display having a plurality of pixel circuits each comprising a memory device, a drive transistor and a light emitting device . First pixel data is measured from the first pixel circuit through the monitor line. Second pixel data is measured from the first pixel circuit or from the second pixel circuit via the monitoring line or another monitoring line. Using one of the measured first pixel data and the measured second pixel data to remove common garbage from the other of the measured first pixel data and the measured second pixel data to generate Clear data for parameter extraction of said first pixel and / or second pixel.
