The various embodiments of the present invention are disclosed in the drawings, and in the claims However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified manner.

Referring to FIG. 1, FIG. 1 is a flow chart showing a method of operating a touch display device according to an embodiment of the present invention. An aspect of the present invention provides a method for operating a touch display device. First, as shown in step S100, detecting whether a plurality of touch sensing units of the touch display device operate normally, the detection is transparent. After the wafer inside the touch device is performed, the operation of each touch sensing unit should be obtained after the detection.

Then, in step S200, the proportion of the abnormal operation of the touch sensing unit is calculated, and whether the ratio is greater than a predetermined value is determined to determine whether the touch function can be normally executed to determine whether the touch display device can enter the normal mode. Here, the ideal preset value for judging whether the touch function can be normally executed is 40%. However, in practice, this ratio of 40% is not applied to limit the invention, and the ratio can be adjusted to 30% or 50%.

If the proportion of the non-normal operation of the touch sensing unit is not greater than the predetermined value, the touch display device is determined to be normally executable, and proceeds to step S300. On the other hand, if the proportion of the non-normal operation of the touch sensing unit is greater than a predetermined value, the touch display device is determined to be unable to perform normally, and proceeds to step S400.

In step S300, since the touch display device is determined to be normally executable, the touch display device is brought into the normal mode, and the user can normally use the touch display device through the better touch sensing unit.

In step S400, since the touch display device is determined to be unable to perform normally, the touch function of the touch display device cannot be performed normally. Therefore, the touch display device is designed to jump out of the reminder window and use the reminder window to The touch method performs the action.

In one or more embodiments of the invention, the reminder window is designed to operate in a non-touch manner. For example, the user can close the reminder window by pressing a physical button or voice control. This physical button can be a power button or a volume button. Here, while displaying the reminder window, the touch The speaker of the display device can also put a reminder sound to remind the user to pay attention.

The setting of the reminder window is mainly for the user to be able to use the touch display panel even if the user cannot use the touch display panel normally. For example, a reminder window asks the user if there is a need for rescue.

In step S500, it is determined whether the user is required to perform an emergency action by whether the reminder window is closed within a predetermined time. If the reminder window is not closed at the predetermined time, the process proceeds to step S600; otherwise, if the reminder window is closed at the predetermined time, the process proceeds to step S700.

In this embodiment, the predetermined time is about 30 seconds, and the setting of 30 seconds is to ensure that the rescue is performed as soon as possible when the accident occurs, and the touch display device may not have other methods for speeding up the help, so only 30 seconds is set. After waiting for the user's reaction time, the touch display device automatically performs an emergency action after 30 seconds.

Step S600 is to cause the touch display device to perform an emergency action. In one or more embodiments of the present invention, the emergency action includes dialing an emergency telephone number, and the emergency telephone number can be preset according to the location network, for example, if the user is in the United States, the emergency telephone number is automatically set to 911. If the user is in Taiwan, the emergency call is automatically set to 110. In addition, the emergency action in step S600 may also include transmitting the coordinates of the global positioning system (GPS) of the touch display device to the nearby rescue unit. Similarly, the nearby rescue unit may also be pre-set according to the location network. .

Step S700 is to bring the touch display device into a sleep mode. Stop the touch when the touch function does not work and the user does not need to take urgent action Controlling the operation of the display device to enter a sleep mode. In actual design, the reminder window is turned off within a predetermined time period to indicate that the user does not need to perform an emergency action. At this time, the touch display device can perform any non-emergency action, and does not have to enter the sleep mode, and the touch display device can also Enter normal mode.

In this way, when the touch function of the touch display device is not working properly, the touch display device will display a reminder window, and the user can select whether to perform an emergency action on the reminder window in a non-touch manner, and avoid the user. The situation where you cannot use the touch function because you cannot use the touch function.

In one or more embodiments of the present invention, the physical button may be designed to accept the reminder window in addition to closing the reminder window. The content of the reminder window teaches the user how to operate by pressing the physical button. For example, pressing the volume down button can close the reminder window without performing an emergency action, and pressing the volume up button indicates agreeing to the reminder window, thereby accelerating the emergency action.

In one or more embodiments of the present invention, the touch sensing unit includes a plurality of sensing electrodes and a plurality of driving electrodes, and the sensing electrodes and the driving electrodes are insulated from each other, and the touch display device includes a touch wafer, and the touch wafer is electrically connected. Induction electrode and drive electrode. In the detecting process of step S100, the touch chip includes a plurality of signals for driving the driving electrodes, and the touch wafer receives the capacitance value signals detected by the sensing electrodes. In detail, detecting whether the touch sensing unit is normally operated is to receive the signal detected by the sensing electrode by the touch wafer, and to determine whether the driving electrode and the sensing electrode operate normally according to whether the signal is normal or not.

For example, assume that the touch wafer is in the sensing electrode under normal conditions. The range of the raw data detected is about 6000~8000. If the value detected by the touch chip on the sensing electrode is 4,000 or less, the touch is poor. As mentioned above, when 40% of the sensing electrodes of the touch sensing unit detect bad raw data, the touch panel is considered to be inoperable and has no touch function.

In one or more embodiments of the present invention, step S100 is designed to start detecting when the power is turned on, the standby screen is released, or the sleep mode is released, so if the user accidentally closes the reminder window within 30 seconds, the emergency cannot be performed. Action, you can restart by simply rebooting or releasing the standby screen.
