Abstract
A display system is disclosed that is capable of switching between graphics processing units (GPUs). Some embodiments may include a display system, including a display, a timing controller (T-CON) coupled to the display, the T-CON including a plurality of receivers, and a plurality of GPUs, where each GPU is coupled to at least one of the plurality of receivers, and where the T-CON selectively couples only one of the plurality of GPUs to the display at a time.
Claims20
A display system, comprising:
- a display;
- a timing controller (T-CON) coupled to the display, the T-CON comprising a plurality of receivers;
- and
- a plurality of GPUs, wherein each GPU is coupled to at least one of the plurality of receivers, and wherein the T-CON selectively couples only one of the plurality of GPUs to the display at a time.
1 more element
A method of switching between GPUs in a display system, the method comprising the acts of:
- updating a display from a first GPU;
- determining if the first GPU has entered a blanking interval;
- in the event that the first GPU has entered a blanking interval, determining if another component within the display system has requested a GPU switch;
- in the event that the another component within the display system has requested a GPU switch, switching to a second GPU, wherein the act of switching to the second GPU occurs without determining a timing signal of a video signal from the second GPU.
1 more element
A T-CON, comprising:
- a plurality of receivers, wherein:
- each receiver comprises a PLL;
- and
- the T-CON selectively couples to only one of a plurality of GPUs at a time.
