Description

  The present invention relates to a protection mechanism for a touch panel, and more particularly, to a protection method for a resistive touch panel and an electronic device using the method.

  With the rapid development of modern science and technology, for example, most electronic devices such as PDAs, mobile phones, notebook computers, etc. have improved the convenience of operation by arranging touch panels. In terms of various touch panels, the resistive touch panel can be input using any medium such as a touch pen, a finger, a card, etc., and the touch position determination accuracy and response speed are also very high. High and fast, it has become the mainstream of market development.

  Conventionally, the application of a resistive touch panel to an electronic device usually does not have a display mechanism of a touch pressure state. As a result, when the user improperly applies a load exceeding the maximum pressure value that the resistive touch panel itself can accept, such as a hardness unit of 3H, for example, for a long time or momentarily, the resistive touch panel is permanently damaged. There is a high possibility that

  In view of this, the present invention protects a resistive touch panel that can generate a warning window and notify the user when a load exceeding the maximum pressure value that the resistive touch panel itself can accept is improperly applied by the user. Provide a method.

  The present invention provides a method for protecting a resistive touch panel, which includes determining whether a contact action has occurred on the resistive touch panel. When the contact action occurs, the analog action change value generated between the upper and lower substrates of the resistance touch panel is measured and the analog resistance change value is converted into a digital pressure value. Subsequently, it is determined whether or not the digital pressure value is larger than a predetermined threshold value (digital numerical value). If the digital pressure value is larger than a predetermined threshold value, a warning window is generated and the warning window is displayed via the resistance touch panel.

  The present invention also provides a computer-readable recording medium for use in storing a computer program. The computer program is installed in a computer system and can cause the computer system to execute the above-described resistance touch panel protection method.

  The present invention also provides an electronic device including a resistive touch panel and its processing module. The processing module is connected to the resistive touch panel and determines whether a contact act has occurred on the resistive touch panel. When the contact action occurs, the processing module further determines the analog resistance change value generated by the contact action between the upper and lower substrates of the resistive touch panel, and converts the analog resistance change value into a digital pressure value. To determine whether the digital pressure value is greater than a predetermined threshold. The processing module further generates a warning window and displays the warning window via the resistive touch panel.

  Based on the above, the method for protecting a resistive touch panel provided by the present invention is used by generating a warning window when the user improperly applies a load exceeding the maximum pressure value that the resistive touch panel itself can accept. To notify the user that the user needs to change the operation method of the resistive touch panel, thereby avoiding damage to the resistive touch panel and increasing its service life.

  It should be understood that the above general depiction and the specific embodiments described below are illustrative and interpretive, and cannot limit the scope claimed by the present invention.

FIG. 1 is a schematic diagram illustrating an electronic device according to an exemplary embodiment of the present invention. FIG. 2 is a flowchart illustrating a resistance touch panel protection method according to an exemplary embodiment of the present invention.

  Reference will now be made in detail to the drawings of the present invention, examples of which are illustrated. In addition, as much as possible, the same display elements / members / symbols used in the drawings and embodiments represent the same or similar parts.

  FIG. 1 is a schematic diagram illustrating an electronic device 100 in an exemplary embodiment of the invention. Referring to FIG. 1, the electronic device 100 may be, for example, a notebook personal computer, a PDA, or a mobile phone, but is not limited thereto, and it is a processing module 101 and a resistive touch panel 103 connected to the processing module 101 and a memory. Including 105. The memory 105 may be, for example, a complementary metal-oxide-semiconductor (CMOS) memory, but is not limited to this and is hereinafter referred to as a CMOS memory 105.

  In the present exemplary embodiment, it is assumed that the maximum pressure value accepted by the resistive touch panel 103 itself is a hardness unit 3H (but not limited to this), that is, upper and lower substrates of the resistive touch panel 103 (not shown) The analog resistance change value that occurs during) must not exceed 2KΩ (but is not limited to this). Further, the CM0S memory 105 has at least one predetermined threshold value (predetermined threshold value, for example, but not limited to the digital value E0) and the total frequency that the resistive touch panel 103 has previously generated a warning window ( For example, 2 but not limited to this is recorded.

  In the exemplary embodiment, the processing module 101 determines whether a contact act has occurred on the resistive touch panel 103 (for example, the user has touched the resistive touch panel 103 with a finger, a touch pen, or other medium). Whether or not). In addition, the processing module 101 first warns that a predetermined threshold (that is, E0) and the resistance touch panel 103 in the CMOS memory 105 before the contact action is performed on the resistance touch panel 103. Reads the total frequency (ie 2) that generated the window and temporarily stores it in an internal buffer memory (not shown).

  In this way, when the processing module 101 determines that the user has touched the resistive touch panel 103 with a finger, a touch pen or other medium (ie, a contact action has already occurred), the processing module 101 Analog resistance change value generated between the upper and lower substrates of the resistive touch panel 103 (that is, the X axis when one of the upper and lower substrates of the resistive touch panel 103 is the X axis and the other is the Y axis) The resistance value between the Y axes) is measured, and the analog resistance change value is converted into a digital pressure value to determine whether the digital pressure value exceeds a predetermined threshold value (that is, E0).

  In this exemplary embodiment, when the digital pressure value is greater than a predetermined threshold (ie, digital pressure value> E0), the analog resistance change value generated by the contact action between the upper and lower substrates of the resistive touch panel 103 is: Indicates that it is greater than 2KΩ. In other words, the action of the user touching the resistive touch panel 103 with a finger, a touch pen or other medium has already exceeded the maximum pressure value (ie, hardness unit 3H) that the resistive touch panel 103 itself can accept, And belong to inappropriate or excessive operation.

  As a result, the processing module 101 immediately generates a warning window 107 and displays the warning window 107 via the resistance touch panel 103. For example, the warning window 107 indicates that “the contact pressure is too high, and the user is careful. By notifying the user that the operation method of the resistance touch panel needs to be changed by notifying the user such as “I want to do”, the permanent touch panel 103 is prevented from being permanently damaged. The service life of can be increased.

  Further, in order not to affect the normal display of the resistive touch panel 103, after displaying the warning window 107, the processing module 101 automatically starts after a predetermined time (for example, after 3 seconds, but not limited to this). Then, the warning window 107 is closed.

  However, in this exemplary embodiment, when no contact action has occurred (ie, the user is not touching the resistive touch panel 103 with a finger, touch pen or other medium), the processing module 101 warns. The window 107 is not generated. Further, when the digital pressure value converted by the processing module 101 is not larger than a predetermined threshold (that is, the digital pressure value <E0), the analog resistance change value generated by the contact action between the upper and lower substrates of the resistive touch panel 103 is , Not greater than 2KΩ. That is, the action of the user touching the resistive touch panel 103 with a finger, a touch pen or other medium does not exceed the maximum pressure value (ie, hardness unit 3H) that the resistive touch panel 103 itself can accept, And safe operation. Thus, the processing module 101 does not generate the warning window 107.

  In order to provide the manufacturer of the electronic device 100 with a basis for later maintenance, in the exemplary embodiment, after displaying the warning window 107, the processing module 101 determines the magnitude of the digital pressure value to which the warning window 107 corresponds. The occurrence time (for example, year / month / day format) is recorded in the CMOS memory 105 and 1 is added to the current total frequency (ie, 2), and then the total frequency (ie, 3) after the accumulation is shown. Record in CMOS memory 15 instead of full frequency (ie 2).

  In this way, when the user submits the electronic device 100 for repair reasoning that the resistive touch panel 103 of the electronic device 100 has been damaged, the manufacturer of the electronic device 100 immediately records data in the CMOS memory 105. By reading (that is, the total frequency of occurrence of the warning window 107), it can be clarified whether or not the user has performed an inappropriate operation on the resistive touch panel 103. This can be a basis for maintenance of the electronic device 100.

  Based on the above, FIG. 2 is a flowchart illustrating a method for protecting a resistive touch panel according to an exemplary embodiment of the present invention. Referring to FIG. 2, the method for protecting a resistive touch panel of the present exemplary embodiment includes the following. First, the current total frequency, which is the frequency at which the resistive touch panel previously generated a warning window, is read in the memory (step S201). Subsequently, for example, it is determined whether or not a contact act on the resistive touch panel has occurred, such as touching the resistive touch panel with a user's finger, touch pen, or other medium (step S203).

  If a contact action has occurred, the analog resistance change value generated between the upper and lower substrates of the resistive touch panel is measured by the contact action (step S205), and the analog resistance change value is converted into a digital pressure value ( Step S207). Thereafter, it is determined whether or not the digital pressure value is greater than a predetermined threshold value (step S209). When the digital pressure value is larger than the predetermined threshold value, a warning window is generated (step S211), and the warning window is displayed via the resistance touch panel (step S213).

  Further, when no contact action occurs or the converted digital pressure value does not exceed a predetermined threshold value, no warning window is generated (step S219).

  In this exemplary embodiment, after the warning window is displayed, the magnitude of the digital pressure value corresponding to the warning window and the generated time are recorded in the memory, and the current total frequency is accumulated by 1 and then accumulated. All subsequent frequencies can be recorded in memory instead of the current total frequency (step S215). In addition, since the normal display of the resistance touch panel is not affected, the warning window can be automatically closed after a predetermined time after displaying the warning window (step S217). Further, steps S215 and S217 after displaying the warning window are not limited in order.

  Here, it should be noted that the method for protecting the resistive touch panel can be executed on a computer system, for example. In other words, the resistance touch panel protection method of the above exemplary embodiment is designed as a computer program, and the computer program is stored in a medium that can be read and stored using a computer, such as an optical disk or a hard disk, for example. The system can be loaded to enforce the resistive touch panel protection method of the exemplary embodiment on a computer system.

  In summary, the resistance touch panel protection method provided by the present invention is used by generating a warning window when the user improperly applies a load greater than the maximum pressure value that the resistance touch panel itself can accept. This informs the user that the user needs to change the operation method of the resistive touch panel, avoids damage to the resistive touch panel, and increases its service life.

  In addition, manufacturers of electronic devices that have a resistive touch panel read the recorded data (that is, the total frequency of occurrence of warning windows) in the memory (that is, CMOS memory), so that the user is inappropriate for the resistive touch panel. Thus, it is possible to clarify whether or not the damage has been caused by performing a proper operation, which can be used as a basis for the subsequent maintenance of the electronic device.

  Although the present invention has been disclosed by the embodiments as described above, it is not intended to limit the present invention, and any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is based on what is limited to the claims.
