Problems solved by technology

[0002] The large-screen in-vehicle system provides a user experience similar to that of a tablet computer, but due to the large size of the display screen, especially a display screen larger than 15 inches will occupy most of the space in the center console, which will have a negative impact on the structural layout of the car machine in the center control part. It is very troublesome. It is impossible to arrange traditional physical buttons next to the screen like a conventional car machine, and if the buttons or knobs of the conventional car machine layout are used to operate, the cost is relatively high, and the position of each button needs to be designed separately and the panel layout is complicated. Therefore, the physical buttons are often omitted in large-screen machines, and only rely on the capacitive touch screen to operate various menus. However, when using the capacitive touch screen to operate the vehicle system, blind operations cannot be performed, and you need to look at the screen to operate, which brings serious driving problems. security issues

Embodiment

[0022] This embodiment provides a capacitive touch screen, such as figure 1 and 2 As shown, at least one mechanical part 20 for operating the capacitive touch screen 10 is installed on the capacitive touch screen 10. The mechanical part 20 is a conductor. When the finger touches the mechanical part 20 during operation, the electric charge of the human body will be Conducted to the mechanical part 20, at this time, the human body and the mechanical part 20 can be regarded as a capacitor, and the mechanical part 20 is equivalent to the touch effect of the human finger on the capacitive touch screen 10, so that the capacitance The touch screen 10 generates a touch response, and the touch response can be converted into an operation command through the processing of the MCU to operate the corresponding menu of the vehicle system.

[0023] Can, but is not limited to, such as image 3 As shown, the mechanical part 20 is installed and fixed on the capacitive touch screen 10 by using...

Abstract

The invention relates to the field of touch screens, and discloses a capacitive touch screen, which is characterized in that at least one mechanical part for operating the capacitive touch screen is provided on the capacitive touch screen, and the mechanical part is a conductor. The capacitive touch screen can perform blind operation, improves driving safety, and has simple structure and low cost.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a capacitive touch screen which can be controlled and operated by mechanical parts. Background technique [0002] The large-screen in-vehicle system provides a user experience similar to that of a tablet computer, but due to the large size of the display screen, especially a display screen larger than 15 inches will occupy most of the space in the center console, which will affect the structural layout of the car machine in the center control part. It is very troublesome. It is impossible to arrange traditional physical buttons next to the screen like a conventional car machine, and if the buttons or knobs of the conventional car machine layout are used to operate, the cost is relatively high, and there are problems such as the need to separately design the position of each button and the complex layout of the panel. Therefore, the physical buttons are often omitted in large-screen m...
