This quetsion is from on touch panel vendor in China. Their customers usually require that the panel resistance should be like Rx-x =200 – 500 Ohms, Ry-y= 600 – 100Ohms. This vendor wants to know why this kind of requirement is needed and whether it is needed for TI resistive touch controllers. Besides, what will happen if the panel resistance goes up to 2k or 3k Ohms?
