First Claim
1. A panel, comprising:
- a plurality of first signal lines to convey control signals;
a sensing module comprising a plurality of shift registers connected in series;
a plurality of second signal lines electrically connected to the sensing module; and
a plurality of sensor units arranged to receive the control signals from the first signal lines, wherein each of the sensor units is configured to provide a sense signal to the sensing module via one of the second signal lines, and wherein each for the second signal lines is connected to one of the shift registers such that the shift registers connected to two adjacent second signal lines are separated by at least another one of the shift registers.

Abstract
An integrated touch panel has a display pixels arranged in a two-dimensional array of rows and columns connected to a plurality of gate lines and data lines. Each gate line receives a gate line signal for controlling the pixels in a row, and each data lines provides display data to the pixels in a column. The touch panel is connected to a sensing module having a plurality of shift registers connected in series. The touch panel has a plurality of sensor units arranged in sensor rows and sensor columns. Each sensor row receives gate line signals from a gate line, and each sensor column is connected to a sensor signal line for providing a touch signal to a shift register in the sensing module such that the shift registers connected to two adjacent sensor signal lines are separated by a different shift register is the series.

11. A method for touch sensing, comprising:
-
connecting a plurality of shift registers in a series, each shift register arranged to receive a clock signal; and coupling a plurality of sensor units to the shift registers through a plurality of signal lines, wherein each of the signal lines is connected to one of the shift registers such that the shift registers connected to two adjacent signal lines are separated by at least another one of the shift registers, wherein each sensor unit is arranged to provide a first signal indicative of a touch event through one of the signal lines, and wherein each of the shift registers comprises a latching unit operable in a first state and a second state, such that a shift register is configured to output a second signal to a subsequent shift register in the series in response to the clock signal only when the latching unit in said shift register is operated in the second state, and wherein the latching unit is operable in the second state only when said corresponding shift register receives at least one of the first signal from one of the signal lines and the second signal from a preceding shift register in the series. - View Dependent Claims (12, 13, 14, 15, 18, 19, 20)
