摘要:
A frame of pixel data may be burst at a higher frame rate to create a lower effective refresh rate when the actual image update rate is lower than the frame rate. This results in the ability to power manage the transmit portion of the display engine and the receive portion of the panel electronics, while reducing display initiated repetitive memory traffic to conserve power.
摘要:
Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a. current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

摘要:
Techniques are described to transmit commands to a display device. The commands can be transmitted in header byte fields of secondary data packets. The commands can be used to cause a target device to capture a frame, enter or exit self refresh mode, or reduce power use of a connection. In addition, a request to exit main link standby mode can cause the target enter training mode without explicit command to exit main link standby mode.
摘要:
A host chipset heartbeat may be utilized, in some embodiments, to handle interrupts from external devices on a power efficient basis. The availability of the host chipset heartbeat may be signaled to external devices and those external devices may time their activities to a period of time when not only are resources available, but the assertion of the activity is advantageous because the host chipset is already transitioning from a lower power consumption state.
摘要:
In some embodiments, an electronic apparatus comprises at least one processor, a plurality of components, and a policy engine comprising logic to receive latency data from one or more components in the electronic device, compute a minimum latency tolerance value from the latency data, and determine a power management policy from the minimum latency tolerance value.
摘要:
A scheme to facilitate deterministic thermal management by having either device connected via a link to generate a thermal management request based on one device's thermal capability and the present conditions. The request is transmitted over the link to the other device with a specific sleep period. Consequently, the receiving device responds with an acknowledgement within a pre-configured or pre-agreed response time.
摘要:
Various embodiments are generally directed to an apparatus, method and other techniques to identify one or more display segments of a display panel, each display segment associated with one of a plurality of lanes of a main link coupled with the interface, independently control enabling and disabling of the display segments and associated lanes, and communicate information on each of the lanes of the main link associated with enabled display segments, and to withhold communicating information on each of the lanes of the main link associated disabled display segments.
摘要:
Methods and apparatus relating to adaptive partial screen update with dynamic backlight control capability are described. In an embodiment, logic causes retrieval of a full frame of content (to be displayed on a display device) based at least in part on an amount of partial screen change to be performed. Other embodiments are also disclosed and claimed.
摘要:
Techniques are described to transmit commands to a display device during vertical or horizontal blanking intervals. The commands can be transmitted using fields that would otherwise be used to transmit color information. A Low Voltage Differential Signaling (LVDS) compliant interface can be used to transmit the commands.
