Problems solved by technology
However, touch screens that can sense multiple contact points at the same time are generally more sophisticated and expensive, and with the miniaturization of electronic devices, the area of the touch screen is relatively smaller, so the user touches the touch screen at the same time. The operation of multiple positions of the touch screen is very prone to misoperation, therefore, the use of the known touch screen still has its shortcomings and needs to be improved

Embodiment Construction
[0018] For the dual-touch integrated control system and method of the present invention, please refer to figure 1 The block diagram of the dual-touch integrated control system shown includes a touch screen 11 , a touch panel 12 , an analog-to-digital converter 13 , an analog-to-digital converter 14 , a microprocessor 15 , and a display controller 16 .
[0019] The aforementioned touch screen 11 is, for example, a liquid crystal display (LCD), light emitting diode (LED), or organic light emitting diode (OLED) touch screen, which can display information and receive user touch input. The aforementioned touch panel 12 is, for example, a resistive or capacitive touch panel, which can receive user's touch input.
[0020] The aforementioned analog-to-digital converter 13 is electrically connected to the touch screen 11 and the microprocessor 15, and is used to convert the analog touch input signal generated on the touch screen 11 into digital touch input information, so as to be used...

The invention relates to a double-touch-control integration control system and a method thereof. The double-touch-control integration control system comprises a touch-control screen, a touch-control panel and a microprocessor. The touch-control screen is used for displaying information and receiving a first touch-control input; the touch-control panel is sued for receiving a second touch-control input; the microprocessor is electrically connected with the touch-control screen and the touch-control panel and is used for receiving the first touch-control input generated on the touch-control screen and the second touch-control input generated on the touch-control panel; wherein, an object which is displayed on the touch-control screen is selected for the first touch-control input; and the microprocessor carries out the corresponding operation on the selected object according to the second touch-control input.
Description
technical field [0001] The present invention relates to the technical field of touch screen control, in particular to a dual touch integrated control system and method. Background technique [0002] Generally speaking, an electronic device provides a menu screen for users to easily use the functions provided by the electronic device. Since the portable information terminal has been developed into a small size that is easy to carry, the method of key input has become quite difficult to use. Therefore, the method of using a touch screen for input is gradually being used, which uses a finger or a stylus to select or input information, so as to increase the convenience and comfort of the portable information terminal. [0003] Most of the above-mentioned touch screen design methods can only sense one contact point, which will be limited in application. For example, because of the size of most portable information terminals, most menu columns must be packed closely. Displayed o...
