What is how to turn off touch screen?

Okay, here's the information about disabling touchscreens in Markdown format with the linked keywords:

Disabling a touchscreen depends heavily on the device you're using. Here's a breakdown by common device types:

Windows: In Windows, the most common method is through the Device%20Manager. You can find your touchscreen device (usually under "Human Interface Devices") and disable it. Alternatively, some laptops have a dedicated setting in the Control%20Panel or settings app. Some Windows tablets also have a hardware toggle for turning the touchscreen on/off.
Android: Directly disabling the touchscreen on most Android devices isn't usually possible without root access and custom ROMs. However, you might find apps on the Play Store that can overlay the screen and prevent accidental touches, essentially acting as a temporary Touchscreen%20Disable solution.
iOS (iPhone/iPad): Similar to Android, iOS doesn't offer a built-in toggle to completely disable the touchscreen. Guided Access can restrict use to a single app and disable certain screen areas, which might be a workaround in some situations but isn't a true Touch%20Screen%20Deactivation.
Laptops/Tablets (General): Check your device manufacturer's website for specific instructions or Driver%20Updates that might include touchscreen control options.

Important Considerations:

Disabling the touchscreen will mean you'll need to rely on other input methods, such as a mouse or keyboard.
Be careful when disabling devices in the Device Manager, as disabling the wrong device can cause other problems.
If you're having touchscreen issues, consider updating your Touchscreen%20Driver before disabling it completely. A driver issue might be the cause of the problem.
