Problems solved by technology

However, the bonding material has the characteristic of easy moisture absorption. Once it absorbs too much water vapor, it is easy to make the touch display device operate in an environment with high humidity, which may not only cause electrical changes in electronic devices, but may even lead to touch display device malfunction Fog, reducing viewing comfort for users

Embodiment Construction

[0036] Please refer to figure 1 , figure 1 As an embodiment of the touch control system of the present invention, the touch control system 10 includes a touch panel 11 and a touch controller 12. The touch panel 11 can be operated in a touch mode and a dehumidification mode. When operating in a touch mode, the touch panel 11 is used to sense whether there is a touch event. When operating in the dehumidification mode, the touch panel 11 uses internal components to generate heat to remove moisture. The touch controller 12 is electrically coupled with an external power supply 13, a humidity sensor 14, and an external system 15. The external power supply 13 can be an AC power supply or a DC power supply. The external system 15 is, for example, a notebook computer or a display screen. control system. The touch panel 11 can be divided into a touch area 111 and a wiring area 112. The touch area 111 is configured with a plurality of transmitting electrodes 113 and receiving electrode...

Abstract

The present invention provides a touch controller and a dehumidifying method applied to a touch panel; the touch panel is electrically coupled to a touch controller; the touch controller comprises a sensor processing unit, a power management unit, and a switching unit. The touch panel includes a plurality of transfer electrodes, each transfer electrode comprising a first end and a second end; the first end and the second end are electrically coupled to the switch unit individually. The dehumidification method comprises the following steps: the sensor processing unit judges whether the dehumidification condition is satisfied according to the received signal;when the determination is YES, causing the power supply management unit to generate a first voltage value and a second voltage value; electrically connecting the first terminal of the transfer electrode with the first voltage value through the switching unit and electrically connecting the second terminal of the transfer electrode to the second voltage value is electrically coupled. The water vapor or humidity of the touch panel itself can be reduced by the present invention.

Description

technical field [0001] The invention provides a touch controller and a dehumidification method, especially a touch controller and a dehumidification method applied to a touch panel. Background technique [0002] When a touch display device is manufactured, a bonding material is often used to bond the touch panel, the glass layer, the display panel, etc. to each other. Known bonding materials such as optical clear resin (OCR) and optical clear adhesive (Optical Clear Adhesive) , OCA) and other materials. However, the bonding material has the characteristic of easy moisture absorption. Once it absorbs too much moisture, it is easy to make the touch display device operate in an environment with high humidity, which may not only cause electrical changes in electronic devices, but may even cause the touch display device to malfunction Fog reduces the user's viewing comfort. Contents of the invention [0003] In order to solve the above problems, the present invention proposes...
