A Liquid Crystal Display, commonly abbreviated as LCD, is a type of display technology used in watches, televisions, computers, and various other electronic devices. LCDs are composed of two sheets of polarizing material that are placed in between two panels of liquid crystal material. When an electrical current is applied, the crystals align and allow light to pass through them. This creates an image on the LCD, which can be seen by the user.
However, sometimes LCD screens will go black and not work properly. There are several possible causes for this phenomenon. It could be due to a hardware or software issue, or a combination of both. In this article, we will explore the various reasons why LCD screens may go black.
| Cause | Solution |
