PIXEL CIRCUITS FOR AMOLED DISPLAYS |
| 摘要 |
A method and system determine the characteristics of drive devices and load devices in selected pixels in an array of pixels in a display in which each pixel includes a drive device for supplying current to a load device. The method and system supply current to the load device via the drive device in a selected pixel, the current being a function of a current effective characteristic of at least one of the drive device and the load device; measure the current via a measurement line that is shared by adjacent pixels, and extract the value of a selected effective characteristic of one of the drive and load devices from the effect of the current on another of the drive and load devices. Current may be measured via a read transistor in each pixel. |

1. A method of determining the characteristics of drive devices and load devices in selected pixels in an array of pixels in a display in which each pixel includes a drive device for supplying current to a load device, said method comprising
supplying current to said load device via said drive device in a selected pixel, said current being a function of a current effective characteristic of at least one of the drive device and the load device, measuring said current via a measurement line that is shared by adjacent pixels, and extracting the value of a selected effective characteristic of one of said drive and load devices from the effect of said current on another of said drive and load devices. |
