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

Embodiment Construction

[0041] Embodiments of the present invention are described in detail below. The embodiments described below are exemplary only for explaining the present invention and should not be construed as limiting the present invention. If no specific technique or condition is indicated in the examples, it shall be carried out according to the technique or condition described in the literature in this field or according to the product specification. The reagents or instruments used were not indicated by the manufacturer, and they were all commercially available conventional products.

[0042] The present invention is based on the following knowledge and findings of the inventors:

[0043] The touch display device usually uses the touch electrodes to sense the user's touch screen operation, and outputs electrical signals to the touch chip (Touch IC). When the user approaches the touch surface of the touch display device with wet fingers or water is splashed onto the touch surface, altho...

Abstract

The present disclosure provides a touch control component, a method for manufacturing the same, a touch display device, and a method for preventing mistaken touch caused by liquid. The touch control component includes a touch electrode layer configured to sense a touch area within a touch surface, and a light sensing film superposed with the touch electrode layer. A light receiving surface of the light sensing film faces the touch surface. The touch control component has a simple structure and is easy to implement. By sensing the intensity of the reflected light from the touch surface using the light sensing film, the wetted area of the water layer can be identified, thereby effectively avoiding mistaken touch caused by liquid.

Description

technical field [0001] The present invention relates to the technical field of touch control, in particular, to a touch control component and a preparation method thereof, a touch display device and a method for preventing false wet touch. Background technique [0002] Capacitive touch display devices are favored by consumers due to their high sensitivity and the advantages of being easy to support 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, 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 a user's touch operation, resulting in unexpected touch feedback for the user. [0003] Therefore, the current touch display device still needs to be ...
