Organic Light-Emitting Diode (OLED) display panels have become increasingly popular in recent years due to their numerous advantages over traditional LCDs. The power consumption in OLED based displays highly depends on the displayed contents. This paper utilizes the image-dependent power-consuming quality of OLED displays to produce energy-efficient and contrast-enhanced images that consume less power and have better visual quality compared to their original form when displayed on an OLED device. The goal of reducing the power consumption in images is achieved by lowering the RGB intensity levels in color images. This idea is inspired by the “Land-Effect”, which reveals that a full-color image can be generated by using only two color components instead of three. However, in this work, a modified Land-Effect has been proposed to yield better results as compared to the original Land-Effect. The proposed method also uses some image enhancement algorithms such as white balance and retinex filter to produce quality enhanced images that have visually better color contrasts as compared to the original images. The real power consumption of the modified images was measured on Samsung Galaxy A50, an OLED-based mobile device. The experimental results demonstrated that the proposed method reduced the power consumption by 13.16% on average. Moreover, to assess the visual quality of images and to understand the user acceptability of the modified images, a subjective evaluation was also performed. The subjective test results showed a higher preference rate for the modified images as compared to the original images. The proposed system in its current form is suitable for server-side implementation where an image would be modified once and the modified image could be used indefinitely by millions of users on social media platforms.

近年来，有机发光二极管（OLED）显示面板由于其比传统LCD的众多优势而变得越来越流行。基于OLED的显示器的功耗高度取决于所显示的内容。本文利用OLED显示器的图像相关功耗质量来生成节能和对比度增强的图像，与在OLED设备上显示时相比，它们的功耗要低，并且具有比原始形式更好的视觉质量。降低图像功耗的目的是通过降低彩色图像中的RGB强度级别来实现的。这个想法是受“土地效应”启发的，它揭示了仅使用两个颜色分量而不是三个颜色分量就可以生成全彩色图像。但是，在这项工作中 与原始的土地效应相比，已提出一种改良的土地效应以产生更好的结果。所提出的方法还使用一些图像增强算法，例如白平衡和retinex滤镜，以产生质量增强的图像，与原始图像相比，这些图像在视觉上具有更好的色彩对比度。修改后的图像的实际功耗是在基于OLED的移动设备Samsung Galaxy A50上测得的。实验结果表明，该方法平均降低了13.16％的功耗。此外，为了评估图像的视觉质量并了解修改图像的用户可接受性，还进行了主观评估。主观测试结果显示，与原始图像相比，修改后的图像具有更高的偏好率。
