Abstract
The invention relates to a touch screen sensitivity dynamic adjustment method which comprises a customized touch screen using a touch screen sensitivity dynamic adjustment platform to provide a zone-changing sensitivity for an ANDROID operating system.
Description
Technical Field
The invention relates to the field of smart phones, in particular to a method for dynamically adjusting the sensitivity of a touch screen of a mobile phone.
Background
The capacitive touch screen is a common touch screen design mode of a smart phone. After receiving the touch signal, the capacitive touch screen converts the touch data into electric pulses and transmits the electric pulses to the touch screen control IC for processing. The signal is amplified by a low noise amplifier LNA, then is subjected to analog-to-digital conversion and demodulation, and finally is sent to a DSP control chip for data processing.
A capacitive touch screen typically has M x N (M columns and N rows) physical capacitive touch sensors. The M + N sensors form M × N capacitive sensing points, and when a finger of a user approaches the touch screen, the capacitance of the touch screen changes accordingly. The spacing of the sensors, i.e., the distance between adjacent rows or columns, is typically on the order of a few millimeters, and this spacing determines the physical resolution of the touch screen, mxn.
The coordinate system between the capacitive touch screen module and the LCD module is completely different. The pixel coordinates of an LCD module are generally determined by its resolution, e.g., a screen of WVGA, which has a resolution of 800 × 480, i.e., 800 lines of 480 RGB pixels each. Thus, a particular position may be determined by the pixel point (X, Y) in the X and Y directions. The capacitive touch screen module determines a coordinate system according to its original physical dimensions in the X and Y directions. A reasonable mapping method must exist between the two coordinate systems to ensure the correctness of the input and output operations.
