What type of laser pointer works on an lcd?

Answer 1

A laser pointer that operates on an LCD typically uses a red laser, as LCD screens are sensitive to certain wavelengths of light. Red lasers, usually around 630-670 nm, are less likely to cause damage or interfere with the display compared to other colors. It's important to ensure that the laser pointer is used at a safe distance to avoid potential harm to the eyes or the screen itself. Always follow safety guidelines when using a laser pointer around electronic devices.
