OPERATING A TOUCH SCREEN CONTROL SYSTEM ACCORDING TO A PLURALITY OF RULE SETS
First Claim
1. An electronic device comprising:
- a display screen configured for displaying images;
a touch sensor configured to detect user input in a sensing region, wherein said sensing region overlaps with an active area of said display screen;
a host processing system; and
a touch screen control system comprising;
a memory configured for holding rules; and
control circuitry configured for;
updating said display screen in response to image data from said host processing system;
operating according to a first set of rules held in said memory;
in response to receiving an indication from said host processing system, switching from operating according to said first set of rules to operating according to a second set of rules, wherein said second set of rules is held in said memory, and wherein at least one of said first set of rules and said second set of rules defines when said control circuitry updates said display screen in response to said user input; and
operating according to said second set of rules.

Abstract
An electronic device comprises a display screen configured for displaying images, a touch sensor configured to detect user input in a sensing region, a host processing system and a touch screen control system. The touch screen control system comprises control circuitry and a memory configured for holding rules. The control circuitry is configured for updating the display screen in response to image data from the host processing system and for operating according to a first set of rules held in the memory. The control circuitry is also configured, in response to receiving an indication from the host processing system, for switching from operating according to the first set of rules to operating according to a second set of rules.

18. A processor-implemented method for operating a touch screen control system, said method comprising:
-
updating a display screen in response to image data from a host processing system; holding a first set of rules in a memory of said touch screen control system, said memory physically distinct from said host processing system; detecting user input in a sensing region that overlaps an active area of said display screen; operating according to said first set of rules; in response to receiving an indication from said host processing system, switching from operating according to said first set of rules to operating according to a second set of rules, wherein at least one of said first set of rules and said second set of rules defines when said touch screen control system updates said display screen in response to said user input; and operating according to said second set of rules. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
