摘要： Embodiments of the present invention generally provide m Methods and apparatus for reducing power consumption of backlit displays are described. Power consumption is reduced by dimming backlighting by a first scale factor and boosting pixel values by a second scale factor to compensate for the dimming. The scale factors may be constant values. Alternately, one or both of the scale factors may be determined based on pixel values for one or more frames to be displayed and/or one or more frames that have been displayed. For example, scale factors may be calculated based on an average linear amplitude of one or more frames of pixel values or from a maximum pixel value of one or more frames of pixel values. A graphical processing system is described including an integrated circuit capable of transforming a pixel value from a gamma-compensated space to a linear space.

摘要： One embodiment of the present invention sets forth a technique for controlling mode switches in hardware. The resource manager includes an “is mode possible” function that evaluates a given mode in conjunction with the limitations of the hardware to determine if the given mode is feasible. The display driver is configured to call this function to validate a proposed mode before generating commands specifying the state changes for the display heads. The display software interface hardware module within the GPU processes these commands and follows a standard sequence of steps to implement the mode switch. The steps may include interrupts to the resource manager to re-validate the proposed mode, again calling the “is mode possible” function, or perform operations that are not yet supported in the hardware. Advantageously, controlling mode switches in hardware enables less error-prone, more efficient, and more discerning mode switches relative to controlling mode switches in software.
摘要翻译：本发明的一个实施例提出了一种用于控制硬件中的模式切换的技术。资源管理器包括一个“可能的模式”功能，其结合硬件的限制来评估给定的模式，以确定给定模式是否可行。显示驱动器被配置为在生成指定显示器头的状态改变的命令之前调用该功能来验证所提出的模式。 GPU内的显示软件接口硬件模块处理这些命令，并按照标准的步骤顺序执行模式切换。这些步骤可以包括资源管理器的中断以重新验证所提出的模式，再次调用“可能的模式”功能，或执行硬件中尚未支持的操作。有利地，与软件中的控制模式切换相比，硬件中的控制模式切换使得相对于控制模式切换更少的易错，更有效和更挑剔的模式切换。

摘要： A method and system are implemented to dynamically control a display refresh rate. Specifically, one embodiment of the present invention sets forth a method, which comprises the steps of driving a display device at a first refresh rate over a period of time, measuring a number of first content frames with changes in content out of a plurality of content frames that are generated over the period of time for the display device, and driving the display device at a second refresh rate if the number of the first content frames meets a first condition associated with a first threshold reference, and optionally driving the display device at a third refresh rate if the number of first content frames meets a second condition associated with a second threshold reference.
