A customer brings in a mobile device complaining that their screen displays deep blacks and high contrast ratios, but they are concerned about the screen's vulnerability to burn-in with prolonged use of static images. Which type of screen technology is most likely used in this device?
OLED screens are known for their ability to produce deep blacks and high contrast ratios because they do not require a backlight — each pixel emits its own light. However, they are also susceptible to burn-in if static images are displayed for long periods. LCD and IPS screens use backlights and do not produce the same level of deep blacks as OLED screens, and while LCDs can suffer from burn-in, it's far less common than with OLED screens. TN and VA screens are types of LCD screens that also don't match the characteristics described for deep blacks and are not as prone to burn-in as OLED.
