Multipoint capacitive plate module

- Oct 22, 2018 -

The coordinate system between the multipoint capacitive screen module, capacitive touch screen module and LCD module is totally different.The pixel coordinates of an LCD module are generally determined by its resolution. For example, a screen of WVGA has a resolution of 800*480, which means that there are 800 lines with 480 RGB pixels per line.Thus, a specific position can be determined by a pixel (X, Y) in the X and Y directions.The capacitive touch screen module determines the coordinate system based on the original physical dimensions in the X and Y directions.There must be a reasonable mapping method between the two coordinate systems to ensure the correctness of the input and output operations.
