提出了一种节能型LCD手机屏幕以及在不同环境光亮度下, LCD和OLED屏幕功耗大小的计算方法。其中OLED屏幕的功耗使用OPR测试的方法确定, 而LCD屏幕的功耗是通过计算背光和模组的总功耗来确定。实验结果证明, 在FHD和WQHD两种分辨率下, 传统LCD屏幕的功耗明显高于OLED屏幕, 而华星光电的ＩEST节能屏则可以与OLED基本保持相同水平;同时在户外日照环境下, IEST节能屏相较于OLED屏幕有明显优势。

Ａ new power-saving LCD panel was presented, as well as a method for calculating the power consumption of LCD and OLED mobile phone screens under different ambient light intensity. The power consumption of the OLED screen was determined by the OPR test method, and the power consumption of the LCD screen was determined by calculating the total power consumption of the backlight and the module. Experimental results show that, under two resolution of FHD and WQHD, the power consumption of traditional LCD screen is significantly higher than the OLED screen, and IEST energy saving screen by Wuhan Star Optoelectronics Technology Co., Ltd. can basically maintain the same level as the OLED. What's more, IEST panel has obvious advantage compared to the OLED screen in the outdoor sunshine environment.
