Abstract
In some examples, a computing device can include a processor resource and a non-transitory memory resource storing machine-readable instructions to cause the processor resource to receive a signal from a graphics processing unit, cause, based on the signal, a first portion of image data to be sent to a first pixel on a moving image area of the display panel at a first refresh rate over a plurality of frames in response to a first thin film transistor (TFT) associated with the first pixel being on, and cause, based on the signal, a second portion of the image data to be sent to a second pixel on a static image area of the display panel at a second refresh rate over the plurality of frames.
Claims20
A controller, comprising:
- a processor resource;
- and
- a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause the processor resource to:
- cause a first portion of image data to be sent to a first pixel on a moving image area of a display panel at a first refresh rate over a plurality of frames;
- and
- cause a second portion of the image data to be sent to a second pixel on a static image area of the display panel at a second refresh rate over the plurality of frames by:
- sending the second portion of the image data to the second pixel during a first frame of the plurality of frames;
- and
- preventing the second portion of the image data from being sent to the second pixel during a subsequent frame to the first frame.
A display device, comprising:
- a display panel including:
- a first pixel connected to a timing controller via a first transistor;
- and
- a second pixel connected to the timing controller via a second transistor;
- and
- the timing controller, wherein the timing controller is to:
- transmit a select signal to the first transistor and the second transistor during a first frame of a plurality of frames to cause the first transistor and the second transistor to be on during the first frame;
- cause, during the first frame:
- a first portion of image data to be sent to the first pixel in response to the first transistor being on;
- and
- a second portion of the image data to be sent to the second pixel in response to the second transistor being on;
- transmit the select signal to the first transistor during a second frame of the plurality of frames to cause the first transistor to be on during the second frame;
- cause, during the second frame, the first portion of the image data to be sent to the first pixel in response to the first transistor being on;
- and
- prevent, during the second frame, the second portion of the image data from being sent to the second pixel in response to the second transistor being off.
A display device, comprising:
- a display panel including:
- a first pixel connected to a timing controller via a first transistor;
- and
- a second pixel connected to the timing controller via a second transistor;
- and
- the timing controller, wherein the timing controller is to:
- provide a data voltage of the first transistor and the second transistor that is above a threshold voltage during a first frame of a plurality of frames to cause the first transistor and the second transistor to be on during the first frame;
- cause, during the first frame:
- a first portion of image data to be sent to the first pixel in response to the first transistor being on;
- and
- a second portion of the image data to be sent to the second pixel in response to the second transistor being on;
- provide the data voltage of the first transistor that is above the threshold voltage during a second frame of the plurality of frames to cause the first transistor to be on during the second frame;
- cause, during the second frame, the first portion of the image data to be sent to the first pixel in response to the first transistor being on;
- and
- prevent, during the second frame, the second portion of the image data from being sent to the second pixel in response to the second transistor being off.
