Please refer to FIG. 3 , which is a flow chart of the steps of the touch screen screen control method according to an embodiment of the present invention; and please refer to FIG. 1 , FIG. 2 and FIG. 4(A) and FIG. 4(B ) together. 4(C) and 4(D) relate to a specific embodiment of the present invention. The touch screen screen control method of the present invention will be described below with the touch screen control system 1 shown in FIG. It should be noted that the touch screen control method of the present invention is not limited to the touch screen control system 1 shown in FIG. 2.

First, step S1 is performed: determining whether the object boundary of the first boundary region of the object has reached the first display boundary.

Referring to FIG. 4(A), in accordance with an embodiment of the present invention, a contact list is displayed on the display area 11 of the touchscreen 10, and the user can browse the list and select a contact from the contact. However, due to the number of contacts in the contact list More, so at a given point in time, the display area 11 can only display a part of the contacts in the contact list, for example, only 9 contacts can be displayed simultaneously in FIG. 4(A). If this happens on a general touch device, when the user wants to select another contact, it is necessary to scroll back and forth the contact list; especially if the screen stays at the top of the contact list, if you want to roll From the moving picture to the last number of pen data, a large number of scrolling actions must be performed, resulting in inconvenience in use.

In view of this, the present invention provides a touch screen control method to solve the above problems. First, it is determined by the judging module 20 that the object displayed on the display area 11 has its boundary that has reached the display boundary of the display area 11. As shown in FIG. 4(A), in accordance with an embodiment of the present invention, a first border area 91 (the first nine contacts data) of a contact list is displayed in the display area 11, and the first boundary is determined by the determining module 20. Whether the object boundary 93 of the area 91 has reached the display boundary 11a above the display area 11, and if the result is YES, step S2 is performed. It should be noted that how to determine whether the boundary of the object has reached the display boundary of the display area should be familiar to those having ordinary knowledge in the technical field of the invention, and will not be described in the specification.

It should also be noted that, according to an embodiment of the present invention, the object displayed in the display area 11 is not necessarily a contact list. For example, it can also be a web page, an electronic file, a newsletter, an email, and the like. The touch screen screen control method of the present invention can be applied as long as the amount of information of the object is large and cannot be displayed all at the same time in the display area 11. It should be noted that, according to an embodiment of the present invention, the determining module 20 does not necessarily determine whether the object boundary 93 has reached the display boundary 11a above the display area 11, and may also determine other boundary areas of the contact list. Whether the object boundary has reached the display area Other display boundaries of domain 11. For example, if the second boundary area 92 of the contact list is displayed in the display area 11 (the last number of contact information, refer to FIG. 4(D)), the determination module 20 determines the second boundary area 92. Whether the object boundary has reached the display boundary 11b below the display area 11, and if the result is yes, proceed to step S2.

If the object boundary of the first boundary region of the object has reached the first display boundary, then step S2 is performed: detecting the motion track of the object contacting or approaching the touch screen.

Referring to FIG. 4(A), in accordance with an embodiment of the present invention, when the object boundary 93 of the first boundary region 91 has reached the display boundary 11a above the display region 11, the detection module 30 detects the object. In this embodiment, the finger is used, but the invention is not limited thereto. For example, the device such as a stylus may touch or approach the motion track of the touch screen 10. The trajectory of how to detect an object touching or approaching the touch screen should be familiar to those of ordinary skill in the art, and will not be described in the specification.

Next, step S3 is performed: determining whether the motion trajectory is "moving the object instruction in the direction of the second display boundary".

Next, the processing module 40 determines whether the motion trajectory is a "moving object command in the direction of the second display boundary", and if so, proceeds to step S4. The second display boundary is opposite to the first display boundary by two boundaries. As shown in FIG. 4(A), in accordance with an embodiment of the present invention, it is determined in step S1 that the object boundary 93 of the first boundary region 91 has reached the display boundary 11a above the display region 11, so the processing mode is processed in step S3. Group 40 needs to determine whether the motion track is For a "moving object command in the direction of the downward display boundary 11b". Similarly, if it is determined in step S1 that the object boundary of the second boundary area 92 (the last number of contact data, refer to FIG. 4(D)) has reached the display boundary 11b below the display area 11, then in step S3 The processing module 40 needs to determine whether the motion trajectory is a "moving object command in the direction of displaying the boundary 11a upwards". It should also be noted that how to determine whether the motion trajectory is a corresponding instruction should be familiar to those having ordinary knowledge in the technical field of the invention, and will not be described again in the specification.

If it is determined that the motion trajectory is "moving the object instruction in the direction of the second display boundary", then proceeding to step S4: determining whether the motion distance is less than the preset distance.

Then, the processing module 40 determines whether the moving distance of the motion track is less than a predetermined distance, and if so, proceeds to step S5a, otherwise proceeds to step S5b. Regarding how to obtain the moving distance of the motion trajectory and judging whether the moving distance is smaller than the preset distance, it should be familiar to those having ordinary knowledge in the technical field of the invention, and will not be described in detail in the specification.

According to an embodiment of the invention, the preset distance is one-half of the distance between the first display boundary and the second display boundary of the display area, but the invention is not limited thereto. For example, in the present embodiment, the preset distance is one-half of the distance between the display boundary 11a and the lower display boundary 11b above the display area 11.

If it is determined that the motion distance is less than the preset distance, then proceeding to step S5a: displaying the first flip picture of the first boundary area in the display area.

Referring to FIG. 4(B), according to an embodiment of the present invention, if it is determined that the moving distance is less than a preset distance (one-half of the distance between the upper display boundary 11a and the lower display boundary 11b), then the processing mode is followed. The group 40 displays the first flip picture 60 of the first border area 91 in the display area 11.

According to an embodiment of the invention, the flip angle of the first flip picture 60 is proportional to the motion distance of the motion track. Therefore, when the finger continues to move in the direction of the lower display boundary 11b, the moving distance of the motion track is elongated, and the flip angle of the first flip screen 60 is also increased. However, when the finger moves to the direction of the upper display boundary 11a, the moving distance of the motion track is shortened, and the flip angle of the first flip picture 60 is reduced.

According to an embodiment of the present invention, referring to FIG. 4(B), the first flip picture 60 includes a first magnified flip picture 61 and a first reduced flip picture 62, and the processing module 40 is further configured to be close to the upper display border. A portion of 11a displays a first magnified flip screen 61, and a portion near the lower display border 11b displays a first zoom-in flip screen 62. The font of the first enlargement flip screen 61 is enlarged, and a larger display area is used; and the font of the first reduced flip screen 62 is reduced, and a smaller display area is used. It should be noted, however, that the first flip screen 60 does not necessarily need to be presented in this manner.

Next, proceeding to step S6: it is judged whether or not "moving the object instruction in the direction of the second display boundary" is ended.

According to an embodiment of the present invention, it is then determined by the processing module 40 whether the "moving the object command in the direction of the second display boundary" is finished. If yes, the process proceeds to step S7a, and if not, the process returns to step S4. When the user's finger leaves the touch screen 10, the movement track ends, "moving the object in the direction of the second display boundary" The "order command" is also terminated. However, if the user's finger does not leave the touch screen 10 but continues to move in the direction of the second display boundary, it means that the motion track has not ended yet, "moving the object in the direction of the second display boundary" The order "is still continuing.

If the "moving object command in the direction of the second display boundary" is not ended, then proceeding to step S4: determining whether the moving distance is less than the preset distance.

According to an embodiment of the present invention, the processing module 40 then determines whether the motion distance of the motion trajectory is less than a preset distance.

If it is determined that the moving distance is not less than the preset distance, then proceeding to step S5b: displaying the second flip screen of the second border area in the display area.

Referring to FIG. 4(C), according to an embodiment of the present invention, when the moving distance of the motion trajectory continues to be elongated, exceeding a preset distance (half the distance between the upper display boundary 11a and the lower display boundary 11b), Then, the processing module 40 displays the second flip screen 70 of the second border area 92 (the last number of contacts data) in the display area 11.

According to an embodiment of the invention, the flip angle of the second flip screen 70 is proportional to the motion distance of the motion track. Therefore, when the finger continues to move in the direction of the lower display boundary 11b, the moving distance of the motion track is elongated, and the flip angle of the second flip screen 70 is also increased. However, when the finger moves to the direction of the upper display boundary 11a, the moving distance of the motion track is shortened, and the flip angle of the second flip screen 70 is reduced.

According to an embodiment of the present invention, please refer to FIG. 4(C), and the second flip The screen 70 includes a second enlarged flip screen 71 and a second reduced flip screen 72. The processing module 40 is further configured to display the second reduced flip screen 72 near the upper display border 11a and display the portion near the lower display border 11b. The second enlargement flips the picture 71. The font of the second enlargement flip screen 71 is enlarged, and a larger display area is used; and the font of the second reduced flip screen 72 is reduced, and a smaller display area is used. It should be noted, however, that the second flip screen 70 does not necessarily need to be presented in this manner.

Next, proceeding to step S6: it is judged whether or not "moving the object instruction in the direction of the second display boundary" is ended.

In accordance with an embodiment of the present invention, it is then determined by the processing module 40 whether "moving the object command in the direction of the second display boundary" is over.

If the "moving object command in the direction of the second display boundary" has ended, step S7b is performed: the second border area is displayed on the display area.

According to an embodiment of the present invention, referring to FIG. 4(D), when the finger leaves the touch screen 10, it indicates that the motion track ends, and "moving the object instruction in the direction of the second display boundary" has been terminated. The movement distance of the processing module 40 according to the motion trajectory is not less than the preset distance, so the second boundary area 92 is displayed on the display area 11.

By performing the touch screen screen control method of the present invention, the user can quickly switch the boundary areas of the opposite ends of the display object without performing a large number of scrolling actions.

Referring now to Figure 3, and Figures 5(A), 5(B) and 5(C), another embodiment of the present invention is provided.

Another embodiment is to explain the corresponding steps of the touch screen control method of the present invention if the moving distance of the motion track does not exceed the preset distance. Most of the steps in this embodiment are the same as in the previous embodiment, and therefore, only the different steps in the two embodiments are explained.

Steps S1 to S5a: This part is the same as the steps of the previous embodiment, please refer to the description of the previous embodiment. As shown in FIG. 5(A) and FIG. 5(B), when the moving distance of the motion track is less than the preset distance (half the distance between the upper display boundary 11a and the lower display boundary 11b), the processing module is used. The first flip screen 60 of the first border area 91 is displayed on the display area 11.

Next, proceeding to step S6: it is judged whether or not "moving the object instruction in the direction of the second display boundary" is ended.

Similarly, the processing module 40 then determines whether "the moving object command in the direction of the second display boundary" is completed, and if so, proceeds to step S7a, and otherwise returns to step S4. Assuming that the user's finger leaves the touch screen 10 at this time, the motion track ends, and the "moving the object command in the direction of the second display boundary" is also terminated.

If the "moving object command in the direction of the second display boundary" has ended, step S7a is performed: the first border area is displayed on the display area.

According to an embodiment of the present invention, referring to FIG. 5(C), when the finger leaves the touch screen 10, it indicates that the motion track ends, and "moving the object instruction in the direction of the second display boundary" has been terminated. The movement distance of the processing module 40 according to the motion trajectory is less than the preset distance, so the first boundary area 91 is still displayed on the display area 11.

It should be noted that the touch screen control method of the present invention is not limited to the above-described sequence of steps, and the order of the above steps may be changed as long as the object of the present invention can be achieved.
