    • A system and method for determining and applying characterization correlation curves for aging effects on an organic light organic light emitting device (OLED) based pixel is disclosed. A first stress condition is applied to a reference pixel having a drive transistor and an OLED. An output voltage based on a reference current is measured periodically to determine an electrical characteristic of the reference pixel under the first predetermined stress condition. The luminance of the reference pixel is measured periodically to determine an optical characteristic of the reference pixel. A characterization correlation curve corresponding to the first stress condition including the determined electrical and optical characteristic of the reference pixel is stored. Characterization correlation curves for other predetermined stress conditions are also stored based on application of the predetermined stress conditions on other reference pixels. The stress condition of an active pixel is determined and a compensation voltage is determined by correlating the stress condition of the active pixel with the curves of the predetermined stress conditions.

    • A system and method for deriving a sequence of OLED non-uniformity test patterns. A pattern generator generates a full sequence of display patterns according to a transform function, such as a discrete cosine transformation or wavelet transformation. A driver drives a display with each of the sequence of patterns. A sensor senses a property of the display, such as a total current for the display, for each of the sequence of patterns. An extraction unit derives a pixel non-uniformity model using the sensed properties and an inverse of the transform function. Patterns that contribute less than a threshold amount to the non- uniformity model can be identified and deleted to derive a sparse sequence of patterns, which can be stored in a memory. The sparse sequence of patterns can be used to test the display and extract a set of pixel non-uniformity values. The pixel non-uniformity values can be used to generate a correction signal for the display.
    • 用于导出OLED非均匀性测试图案序列的系统和方法。 模式发生器根据变换函数(如离散余弦变换或小波变换)生成完整的显示模式序列。 驱动器驱动具有每个模式序列的显示器。 对于每个图案序列,传感器感测显示器的属性,例如显示器的总电流。 提取单元使用感测到的属性和变换函数的逆,得出像素非均匀性模型。 可以识别和删除贡献小于非均匀性模型的阈值量的模式以导出可以存储在存储器中的模式的稀疏序列。 模式的稀疏序列可用于测试显示并提取一组像素非均匀性值。 可以使用像素非均匀性值来产生用于显示的校正信号。
