Abstract
A method for converting a driving frequency of a touch panel includes receiving a control signal for a display porch time, changing the display porch time based on the control signal, changing a cycle of the horizontal synchronizing signal based on the changed display porch time, and generating a touch driving signal synchronized with the horizontal synchronizing signal.
Claims12
A method for converting a driving frequency of a touch panel, the method comprising:
- receiving a control signal for a display porch time;
- changing the display porch time based on the control signal;
- changing a cycle of a horizontal synchronizing signal based on the changed display porch time;
- and
- generating a touch driving signal synchronized with the horizontal synchronizing signal.
2 more elements
A display device with a touch panel, comprising:
- a display to display an image;
- a touch sensor to sense a touch;
- a driver to control the display;
- and
- a touch driver to provide a touch driving signal to the touch sensor, the touch driving signal synchronized with a horizontal synchronizing signal, wherein the touch driver is to provide a control signal of a display porch time to the driver, and wherein the driver is to change the display porch time based on the control signal.
2 more elements
A method for converting a driving frequency of a touch panel, the method comprising:
- receiving an instruction for a touch driving signal;
- and
- converting a frequency of the touch driving signal based on the instruction, wherein the touch driving signal is synchronized with a horizontal synchronizing signal, which includes a first pulse that repeats at a substantially constant cycle, wherein the touch driving signal includes N second pulses temporally positioned in a corresponding cycle of the horizontal synchronizing signal, a first distance from a first edge of one of the second pulses to a first edge of an adjacent one of the second pulses substantially constant, and wherein converting the frequency of the touch driving signal includes changing the first distance.
