Problems solved by technology

However, its high sensitivity depends on the stability of the electric field near the cover glass. Once environmental factors affect the electric field, false touches are very easy to occur. A typical type of false touch is when the user operates the touch display device with wet hands. The wet part of the water layer is misidentified as the user's touch operation, resulting in unexpected touch feedback for the user
[0003] Therefore, the current touch display device still needs to be improved

Abstract

The invention provides a touch module and a preparation method thereof, a touch display device and a method for preventing false touch caused by wet. The touch module comprises a touch electrode usedfor sensing the touch position, and an optical sensing film arranged on one side of the touch electrode and used for sensing reflected light on the touch surface of the touch module. The inventor finds that the touch module is simple in structure and easy to realize; the optical sensing film can recognize a water layer wetted area by sensing the intensity change of reflected light in the area wetted by water on the touch surface, water-layer false touch can be effectively prevented accordingly, unexpected touch feedback caused by the wetted part can be effectively avoided, and the effect of reducing water layer interference is good; besides, the sensitivity of recognizing false touch caused by water layer wetting is high, and the effect of improving user experience is good.

Description

Technical field [0001] The present invention relates to the technical field of touch control, and in particular to a touch control component and a preparation method thereof, a touch display device and a method for preventing moisture and false touches. Background technique [0002] Capacitive touch display devices are favored by consumers due to their high sensitivity and convenient support for multi-touch, making them occupy most of the market for touch panels of existing smart products. However, its high sensitivity depends on the stability of the electric field near the cover glass. Once environmental factors affect the electric field, it is easy to cause false touches. A typical type of false touch is when the user operates the touch display device with wet hands. The wetted part of the water layer is misidentified as a user's touch operation, which leads to unexpected touch feedback. [0003] Therefore, the current touch display device still needs improvement. Summary of th...
