Abstract
Examples described herein generally relate to a display device and computing device where a display is configured for displaying images, a display controller is configured for receiving image data via a display port when coupled to a computing device, and sending signals to the display, based on the image data, to cause the display to display the images, and a memory is accessible by the display controller for storing a resume image received from the computing device. The display controller is further configured for detecting a power on event, accessing the memory to obtain the resume image, and sending signals to the display to cause display of the resume image based at least in part on detecting the power on event.
Claims20
A display device, comprising:
- a display configured for displaying images;
- a display port configured for receiving image data from a computing device coupled to the display port via a source display port;
- a hardware timing controller configured for sending signals to the display to control display timing for displaying the images corresponding to the image data received via the display port;
- and
- a memory coupled to the hardware timing controller and accessible by the hardware timing controller for storing a resume image received from the computing device,
- wherein the hardware timing controller is further configured for detecting a power on event related to the computing device, accessing the memory to obtain the resume image, and sending signals to the display to cause display of the resume image based at least in part on detecting the power on event.
A computing device, comprising:
- a memory;
- a display interface configured for communicating image data to a display device for displaying on a display;
- and
- at least one processor coupled to the memory and the display interface via a bus, wherein the at least one processor is configured for:
- initiating a power down sequence at the computing device related to decreasing or terminating power provided to one or more components of the computing device including the display interface;
- generating a resume image to be displayed on the display in a subsequent power on event and before the display interface communicates image data to the display device following the power on event;
- and
- sending, as part of the power down sequence and before decreasing or terminating power to the display interface, the resume image to the display device via the display interface, wherein the display device stores the resume image in a memory on the display device that is accessible by a hardware timing controller of the display device.
A method for displaying a resume image based on a power on event at a display device, comprising:
- initiating a power down sequence at a computing device;
- communicating the resume image from the computing device to the display device based in part on the power down sequence;
- storing the resume image in a memory accessible by a hardware timing controller of the display device, wherein the hardware timing controller is configured for sending signals to a display of the display device for controlling timing for displaying images on the display;
- detecting a power on event at the computing device;
- displaying, by the hardware timing controller and on the display device, and based in part on detecting the power on event, the resume image from the memory accessible by the hardware timing controller;
- and
- displaying, on the display device, subsequent images based on image data received from the computing device following the power on event.
