This publication describes systems and techniques directed at minimizing display panel power consumption by selectively reducing a brightness of on-screen content. In aspects, within a display pipeline, display data ordered in hierarchical layers having objects can be passed to a content detector. The content detector may be configured to calculate a probability that objects within each of the hierarchical layers correspond to a visual element being a particular type of content. Each of the hierarchical layers can then be passed to a layer color converter. Based on the probabilities of each of the hierarchical layers, the layer color converter can be configured to adjust a brightness value for each hierarchical layer. The display data within each of the hierarchical layers can then be blended together according to their hierarchy. Through such a technique, brightness values of different on-screen content are selectively adjusted, saving power while still affording a good user experience.
