What is a physical hazard for each of the following computer screens?

A physical hazard for CRT (cathode ray tube) screens is the risk of implosion due to the vacuum inside the tube, which can cause flying glass shards if the screen is broken. For LCD (liquid crystal display) screens, a common hazard is the risk of cuts or injuries from broken glass if the screen is shattered. OLED (organic light-emitting diode) screens can pose hazards related to chemical exposure from the organic materials used in their construction if damaged. Lastly, all types of screens can present ergonomic hazards if not positioned properly, leading to strain or injury from poor posture during use.
