@euphy: I think the D and Q numbers are the LEDs row and column numbers in the infrared display as these LEDs form the matrix of the lights and when we touch the screen the output on the corresponding LEDs associated with those co-ordinate decreases which helps to identify the touch point on the screen and to know more about the these numbers you should look at the datasheet of the device.
