       BACKGROUND 
       [0002]    At present, operating application which runs on some small touch-screen device, usually comprises the following approaches: one is clicking on the desired touch control to execute the command, however, this method has the disadvantage that: the physical area of the touch control is too small on the small touch-screen device, the peripheral button may be touched incorrectly when the corresponding touch control area is touched, which leads to low touch accuracy; another is adding a background to the icon or directly enlarging the physical area of the icon, and clicking on the icon to execute the corresponding command The defect is that: more real area of the screen will be occupied, the production cost increases. Another method is shrinking the icon button, popping up the enlarged icon when the small button is inducted, clicking the enlarged icon to execute commands, such as the patent with the title “touch control system and control method” and publication number CN101930338 A. the disadvantages of such method is that: the operation is complicated, and an accidental contact may be easily caused when the small button is clicked; and a still another method is using a high-end touch screen as much as possible such as high resolution, high sensitivity, or high sensitivity sensor chip, to ensure touch accuracy.

         [0090]    Specifically, as shown in  FIGS. 3-6 ,  FIG. 3  is an example of the wide application of the present invention. From inside to outside, the control area comprises areas  201 ,  203  and  202 . The area  201  is the icon display area, the area  203  is a first non-icon display area outside the area  201 , and the area  202  is a second non-icon display area outside the area  20 .  200  is the state of the icon display area when the icon display area is touched, that is the state after the icon display area receives the touch operation.  204  is the whole control area. The area  205  is the small icon area to be checked in the prior art. When the user touches the icon display area in the control area, the icon display area displays  201  instead of  200 , which prompts the system starts to response. If the screen of the display module or the icon is too small such that the user touch on the area outside coordinates of the icon display area, such as non-icon area  202  or  203 , the icon display area also responses and enters in the state  200 . It does not need to improve the hardware settings or increase the display area, while improves the accuracy of the small touch screen devices, and reduces the touch area false operation caused by small touch area. The display module may set the width and the hierarchy of the non-icon display area according to the available area the icon display area and the distance between adjacent icon display areas. In the prior art, such as the area  205  that needs to be checked is relatively small, in the small touch screen devices, the area  205  is difficult to accurately touch, thereby leading to no response from the system. In the present invention, the programming module can arrange the non-icon display areas hierarchically, set different commands for the non-icon display areas with different hierarchies, and equate the command of one non-icon display area to the command of the area  205  to be checked, when such non-icon display area is touched, it is equivalent to the area  205  to be checked being touched, the command corresponding to the small area  205  to be checked may be executed, and the area  205  is checked. As shown in  FIG. 7 , the rectangle marked with XX at the bottom right corner is the control area, i.e. the button icon, the black rectangle in the middle is a content display area. As one embodiment of the present invention, for the convenience of the touch operation, the control module only set one control area in the screen of the display module, or cancel the visible icon display area, directly set the non-icon display area on a presentation area or blank area, or other screen area that can be used to touch, which facilitates user&#39;s operation during browse. 
         [0091]    The foregoing descriptions are merely exemplary embodiment of the present invention, but are not intended to limit the present invention to it. Any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the present invention shall fall within the protection scope of the present invention.
