Abstract
This paper reports on downsampling-based techniques to achieve low power consumption and fast readout for capacitive touch screen panels. Here, touch interactivity is processed as an image, which is downsampled and reconstructed to estimate the touch position. After the reconstruction, a regional scan is performed around the reconstructed touch location to retrieve accurate touch information. Based on experimental and simulation results, we successfully decreased readout time and power consumption by 11.3 ms (68%) and 8.79 mW (68.7%), respectively, when only 25% sensors were selected. The presented technique yields higher responsivity and lower power consumption while maintaining detection accuracy.
