The present invention relates to an operation method and a display module, and more particularly to a method for operating a touch screen and a display module using the same.

With the needs of users, the development of display devices such as tablet computers and smart phones tends to make the display screen larger to facilitate viewing of articles, messages or videos. However, as the display screen becomes larger, in the case where the user holds the display device with one hand, the range of the touch of the finger on the display screen is relatively small, and more and more areas are not available to the user. It can be touched by holding the display device with one hand. Therefore, this problem is urgently to be resolved.

The invention provides an operation method suitable for a touch screen, which allows a user to hold the touch screen with one hand and operate the full screen with a limited finger movement range.

The invention provides a display module to which the above operation method can be applied.

The operation method of the present invention is applicable to a touch screen. The operation method includes at least the following steps: the touch screen receives the proximity signal, wherein the proximity signal is generated by one hand floating on the touch screen; and the floating screen is displayed according to the proximity signal touch screen. a floating point; detecting a proximity signal and determining whether the hand moves relative to the touch screen; if so, causing the floating indicator point to move closer to the proximity signal and the distance of the floating indicator point is greater than the distance the hand moves relative to the touch screen Detecting whether there is a sensing gesture signal on the touch screen; if so, performing the corresponding function according to the sensing gesture signal.

1 is a block diagram of a display module, and FIG. 2 is a schematic diagram of a display module. Referring to FIG. 1 and FIG. 2 , the display module 100 includes a touch screen 110 , a detecting unit 120 , a computing unit 130 , and a central processing unit 140 . The detecting unit 120 and the computing unit 130 are electrically connected to the touch screen 110. The detecting unit 120 is also electrically connected to the computing unit 130, and the central processing unit 140 is electrically connected to the detecting unit 120. It should be noted that the detecting unit 120 and the computing unit 130 and even the central processing unit 140 are integrated in the touch screen 110. Therefore, the display module 100 can be a smart phone or a tablet.

FIG. 3 is a schematic diagram showing the operation flow of the display module. Referring to FIG. 1 , FIG. 2 and FIG. 3 , in step S110 , the user holds the display module 100 and places the finger on the touch screen 110 . The touch screen 110 of the embodiment is capacitive. The touch screen is so that the user's finger is suspended on the touch screen 110 without directly contacting the touch screen 110, and the finger and the touch screen 110 are effectively separated from each other. The contact distance d (as shown in FIG. 4), the range of the effective distance d can be set according to actual needs, for example, and the value of the effective distance d is proportional to the distance, thereby determining the distance between the finger and the screen. Since the touch screen 110 can be suspended by the finger on the touch screen 110, the proximity signal of the finger approaching the touch screen 110 is received, and the closer the finger is to the touch screen 110, the stronger the signal strength is. On the other hand, according to the proximity signal, the touch screen 110 displays the floating indication point 112 at the corresponding position of the received signal, and the position of the floating indication point 112 is corresponding to the received signal, and as shown in step S112. Detecting the proximity signal and determining whether the hand moves relative to the touch screen, and then, as in step S114, if the proximity signal movement is detected, the floating indication point 112 is moved along with the proximity signal, and the distance of the floating indication point 112 is moved. The distance is greater than the distance the hand moves relative to the touch screen.

Then, in step S120, the detecting unit 120 detects whether there is a sensing gesture signal on the touch screen 110. Then, in step S130, if yes, the corresponding function is performed according to the sensing gesture signal.

In this embodiment, the sensing gesture signal may be linearly slid on the touch screen 110 by the user's finger. The detecting unit 120 detects that the user's finger is linearly sliding on the touch screen 110, and the floating indicating point 112 is along the tangential direction of the sensing gesture signal on the touch screen 110 according to a predetermined ratio. Extend and change position, as shown in Figure 5. This predetermined ratio may be the data built into the central processing unit 140, and after the calculation unit 130 calculates how much distance the floating indication point 112 should move, the floating indication point 112 is moved to the correct position.

Incidentally, the floating indication point 112 can be determined by a combination of gestures. Change position according to several times the predetermined ratio. For example, when the user's finger swiftly slides outward twice in a straight line, the floating indication point 112 can be extended to a multiple of the distance according to the booking ratio; when the user's finger is By rapidly sliding outward three times in a straight line, the floating indication point 112 can be extended forward to twice the distance according to the booking ratio; and so on.

Or, as the user's finger slides linearly on the touch screen 110, the floating indication point 112 extends along the tangential direction of the sensing gesture signal on the touch screen 110 to the edge of the touch screen 110, and the computing unit After calculating the moving distance of the floating indication point 112, the calculation result is transmitted to the central processing unit 140, so that the central processing unit 140 can perform corresponding processing. For example, when another sensing gesture signal is detected, for example, counterclockwise rotation or clockwise rotation, the floating indication point 112 may rotate counterclockwise or clockwise according to the sensing gesture signal, as shown in FIG. 5. The direction of the arrow shown in . Alternatively, when the sensing gesture signal is clockwise sliding, the display screen of the touch screen 110 is enlarged; and when the sensing gesture signal is counterclockwise sliding, the display screen of the touch screen 110 is reduced.

The above-mentioned gesture of sliding the finger outward may move the position of the floating indication point 112 outward, and may also call back the floating indication point 112 by the gesture of the finger sliding inward to make the position of the floating indication point 112. Closer to the finger.

As can be seen from the above, the user can change the position of the floating use point on the touch screen 110 arbitrarily by a combination of gestures (for example, linear sliding or rotating), thereby enabling the floating indication point 112. The position is not accessible to the finger but is touched via the floating indicator point 112 to perform the work performed by the user. Can or program.

In step S120, if the touch screen 110 does not detect the sensing gesture signal, in step S140, the touch screen 110 ends displaying the floating indication point 112.

In summary, in the display module of the present invention, an element that provides a function corresponding to the operation method is provided, so that when the user holds the touch screen with only one hand, the user can also control by the gesture. The floating pointing point moves to a position on the touch screen that the user's finger cannot extend, and uses a gesture to perform the corresponding function. Through such a component arrangement and a program, regardless of the size of the touch screen of the display module, the display module can be operated by such an operation method, which is extremely convenient for the user.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
