In addition, this The number of sensors in the embodiments is only for illustration, and is not intended to limit the number of applicable sensors.

When the user touches the touch sensing area 11, the sensing control module 10 generates a sensing signal corresponding to the touched position of the touch sensing area 11, wherein the type of the sensing signal can be divided into a single sensing signal and a direction Sensitive sensing signal, a single sensing signal represents that the user touches any one of the first sensor 11a, the second sensor 11b, the third sensor 11c or the fourth sensor 11d, and the directional sensing signal represents that the user touches the first sensor 11a. Any one of the sensor 11a, the second sensor 11b, the third sensor 11c or the fourth sensor 11d touches the next adjacent sensor to form a directional touch (for example, sliding to the left or right).

In addition, the sensing control module 10 of this embodiment further provides a function of accurately judging the touch position. When the touch sensing area 11 senses two or more touched positions at the same time, the sensing control The module 10 only generates the sensing signal with the strongest signal corresponding to the touched position. It mainly compares the signal strengths sensed by each sensor and ignores those sensors whose signals are weaker than the strongest signal, thereby improving the accuracy of touch sensing. .

The display control module 20 is connected with the sensing control module 10. When receiving the sensing signal, it executes the action of displaying a visual control display setting menu on the liquid crystal display. Then, the display control module 20 analyzes the sensing signal corresponding to the operation instruction , and generate a control signal corresponding to the operation command, and then output the control signal to the display module 30, so as to execute the decision option, exit option, change option or change setting value in the On-Screen Display (On-Screen Display) setting menu (for example , the adjustment action of color setting value, contrast setting value, brightness setting value, sound setting value, screen horizontal setting value or screen vertical setting value), and the sensing signal corresponding to the decision option and the exit option The type is a single sensing signal, and the sensing signal type corresponding to the change option and the change setting value is a directional sensing signal, so the change option and change setting value are adjusted according to the direction in which the touch sensing area is touched. In addition, the display control module 20 may be, for example, a Microprocessor Control Unit (MCU) in practice.

The display control module 20 further includes a timing unit 21. When receiving the sensing signal, the timing unit 21 starts counting for a predetermined period of time, and within the predetermined time, when the touch sensing area 11 does not sense another touch, The display control module 20 closes the visual control display setting menu. When the touch sensing area 11 senses a touch again within a predetermined time, the display control module 20 continues to display the visual control display setting menu on the liquid crystal display, and the timing Unit 21 resets the timer for a predetermined period of time.
