Touch Screen Controllers

Texas Instruments has long been a leader in the touch screen controller market and maintains the lead in resistive touch screen controllers. We offer both resistive and capacitive touch solutions to support a broad range of performance options. Whether your design requires simple, single-touch or high-performance, multi-touch controllers, TI has the solutions to meet the needs of various touch screen enabled consumer electronic applications.

Benefits

  • Robust sensitivity: Better touch sensitivity with programmable gain and patented analog front ends
  • Reduced System cost: Increased touch panel yields due to highly tolerable Capacitive and Electrode specs
  • Lower Latency: Improved touch response experience from lower latency
  • Low Power Consumption: Prolonged battery life from reduced power consumption
  • Small Footprint: Single chip touch screen controller solution with small device sizes
  • Easy to integrate: Production-ready hardware implementation and software drivers available
  • Clarity: Capacitive touch has less layers of ITO obstructing the screen, providing a clearer picture
  • Durability: Capacitive touch has a layer of safety glass on top of the ITO and LCD panels that provide increased durability
