Abstract
Examples disclosed herein relate to an interactive display. Motion of an input device on a display screen is tracked and pixels of the display screen that have changed based on the tracked motion are updated. Portions of the display screen corresponding to the updated pixels are refreshed.
Claims13
An interactive display system, comprising:
- a display screen;
- an input sensor to track motion of an input device at a predetermined tracking rate;
- a high speed display interconnect to connect the display screen to a graphics card of a display controller;
- and
- the display controller connected to the display screen by the high speed display interconnect, the display controller to:
- select a plurality of pixels, fewer than a total number of pixels, that have changed based on motion of the input device on the display screen determined during tracking,
- wherein the pixels are selected as input is detected by the input sensor;
- transmit pixel data directly to the display screen over the high speed display interconnect, the pixel data only including updates to the plurality of pixels that have changed, wherein the display controller is to transmit the pixel data as the plurality of pixels are selected with no artificial refresh rate limit, and
- retain image data, wherein the image data is retained within pixels of the display screen or in an integrated frame buffer of the display controller.
6 more elements
A method for implementing an interactive display, comprising:
- tracking motion of an input device on a display screen, wherein the display screen comprises at least one of a touch-screen display, a touch-sensitive display, and a multi-touch display;
- selecting pixels that have changed based on and determined during the tracking, wherein the pixels are selected as input is detected an input sensor;
- transmitting, directly, as the pixels are selected, and with no refresh rate limit, a minimum bandwidth transmission from a controller to the display screen over a high speed connection, the minimum bandwidth transmission indicating updates to the selected pixels;
- and
- refreshing portions of the display screen corresponding to the selected pixels, wherein fewer than a total number of pixels of the display screen are refreshed.
2 more elements
A non-transitory computer-readable medium comprising instructions that, when executed, cause an interactive display system to:
- track motion of an input device on a display screen;
- select pixels of the display screen that have changed based on and determined during the tracked motion,
- wherein the pixels are selected as input is detected by an input sensor;
- send directly, as the pixels are selected, to the display screen a transmission only including updates to the selected pixels that have changed with no artificial refresh rate limit to the transmission;
- and
- refresh portions of the display screen corresponding to the selected pixels.
