At CES 2017, Samsung has unveiled a new line of TVs under the QLED umbrella. These are LCD TVs with quantum dot technology. The flagship Q9 is flat, whereas the Q8 is curved. Samsung wants to sell its 2017 LCD TVs as QLED TVs, just like it sold LCD TVs in 2015 and 2016 under the SUHD brand, and under LED before that. Originally, QLED referred to a new type of self-emitting display technology like OLED.

When soundwaves reach the tympanic membrane they cause it to vibrate. The vibrations are then transferred to the tiny bones in the middle ear. The middle ear bones then transfer the vibrating signals to the inner ear.
Once the sound waves travel into the ear canal, they vibrate the tympanic membrane, commonly called the eardrum. The eardrum is a thin, cone-shaped piece of skin, about 10 millimeters (0.4 inches) wide. It is positioned between the ear canal and the middle ear. The middle ear is connected to the throat via the eustachian tube. Since air from the atmosphere flows in from your outer ear as well as your mouth, the air pressure on both sides of the eardrum remains equal. The eardrum is rigid, and very sensitive.
