I see. While OLED burn-in (or permanent image retention) refers to the gradual degradation of pixels on OLED displays, LCDs are susceptible to a similar phenomenon called **image retention**. Image retention occurs when the same image is displayed on the screen for an extended period of time, causing the pixels to retain their same shape and continue producing the same image. This can be temporary or permanent depending on the severity of the case. 

I hope this helps. Let me know if you have any other questions.
