US 2016/0077782 A1 · TERMINAL AND APPARATUS AND METHOD FOR REDUCING DISPLAY LAG

Abstract

An apparatus includes an overlay buffer configured to store overlay data; a touch path logic to: receive first touch events from the first touch sensor panel and generate a first output based on the first touch events, and receive second touch events from the second touch sensor panel and generate a second output based on the second touch events; and a rendering logic to, when the first touch events occur: receive a first video image; receive the first output; and combine the first video image with the overlay data corresponding to the first video image to output at least one combined display image, and, when the second touch events occur: receive a second video image; receive the second output; and combine the second video image with the overlay data corresponding to the second video image to output the at least one combined display image.

Dependent claims

An apparatus for reducing a display lag of a terminal comprising at least one display panel and first and second touch sensor panels corresponding to the at least one display panel, the apparatus comprising:

at least one overlay buffer configured to store at least one overlay data;
at least one touch path logic configured to:
receive first touch events from the first touch sensor panel and generate a first output based on the first touch events, and
receive second touch events from the second touch sensor panel and generate a second output based on the second touch events;
and
at least one rendering logic configured to, when the first touch events occur:
receive a first video image;
receive the first output of the touch path logic;
and
combine the first video image with the overlay data corresponding to the first video image to output at least one combined display image, and to,
when the second touch events occur:
receive a second video image;
receive the second output of the touch path logic;
and
combine the second video image with the overlay data corresponding to the second video image to output the at least one combined display image.

A terminal comprising:

an application processor;
at least one display panel;
first and second touch sensor panels corresponding to the display panel;
and
a processor configured
to receive a video frame for the display panel from the application processor,
to, when first touch events occur on the first touch sensor panel, determine a first touch path based on the first touch events and to update the video frame based on the first touch path and stored first overlay data, and
to, when second touch events occur on the second touch sensor panel, determine a second touch path based on the second touch events and to update the video frame based on the second touch path and stored second overlay data.
