Abstract

The present invention relates to a touch module and a touch screen. The touch module includes a touch panel located on the display module, a main circuit board located outside the casing of the touch screen, a plurality of signal cables connecting the touch panel and the main circuit board, and an equal potential wiring. By setting an equal potential wiring in the touch module to electrically bridge any two signal cables, a short circuit is formed between the shielding layers of the signal cables so that the potentials of different signal cables can be equalized to make the signal cables roughly the same degree of electrostatic or electromagnetic interference from the environment. By making the signals obtained by the signal cables be disturbed to approximately the same degree, the touch module can accurately determine the touch position.
