摘要

在本研究中，提出了一种新的有机发光二极管功率控制算法，该算法使用最佳灰度映射曲线确定。通常，传统的方法会产生颜色失真，或者需要额外的电路来降低功率，而所提出的算法只通过考虑原始图像质量来改变输入图像的灰度级，而不需要额外的线路。特别地，所提出的算法在估计图像退化和功耗之后生成目标函数。接下来，它搜索函数的最小值，并确定最终的灰度映射曲线。仿真结果表明，与传统算法相比，该算法的功耗降低了10.964%，同时保持了较高的图像质量。

OLED Power Control Algorithm Using Optimal Mapping Curve Determination

In this study, a new organic light-emitting diode power control algorithm that uses optimal gray-level mapping curve determination is proposed. In general, conventional approaches produce color distortion or they require additional circuits for power reduction, whereas the proposed algorithm only changes the gray levels of an input image by considering the original image quality without additional circuits. In particular, the proposed algorithm generates an objective function after estimating the image degradation and power consumption. Next, it searches for the minimum value of the function and determines the final gray-level mapping curve. According to the results of simulations, the proposed algorithm reduces the power consumption by up to 10.964% compared with the conventional algorithm, while still preserving the high image quality.
