Abstract:
Disclosed is a method for testing touch screen displays during manufacture. A touch screen controller (TSC) is packaged, and the analog channels of the TSC are characterized, with resulting data being stored for later use. The TSC is programmed, and the touch screen display and TSC are packaged together. The touch screen display is tested using firmware in the TSC, enabling calculation of the inherent capacitances between force and sense lines of the touch screen display when connected to the TSC during operation. The testing involves, for each force and sense line pair, measuring an output signal generated by a receive channel of the TSC coupled to the sense line of that pair. Based upon the data gathered during characterization, and the signals measured during testing, the capacity of the touch screen display is then calculated.

Claim (Index 10):
The system of  claim 8 , wherein the touch signal represents a capacitance between the force line and the sense line; and wherein the touch screen controller includes:\n a compensation circuit having a capacitor configured to be selectively coupled to the force line a given number of times; a capacitance to current converter configured to convert the capacitance to a current; an accumulator circuit including a feedback capacitor and configured to accumulate the current a given number of times to produce an accumulated signal; and a gain stage configured to amplify the accumulated signal to produce the touch data signal.
