Deconstruction of mobile phone screen
Today's smartphones are generally composed of four layers, from top to bottom: cover glass, touch sensor, front panel, and back panel.
Cover glass helps protect devices such as mobile phone touch sensors;
Touch sensors, as the name suggests, are created to assist mobile phone users in operating the phone screen through touch;
The front panel can be equipped with a filter to generate various images that appear on the phone screen;
The backplane plays a crucial role in the mobile phone screen, as it is covered with millions of thin-film transistors;
How to determine whether the inner or outer screen is damaged?
When we use our mobile phones, unfortunately, the screen may get damaged. Generally, there are two scenarios. One is that the outer screen is damaged, and the other is that both the inner and outer screens are damaged. To avoid being ripped off, we must be clear about the condition of our mobile phone, whether it's just the outer screen that's damaged or both the inner and outer screens are damaged.
① Touch: When performing touch operations on the phone, the screen sometimes responds sluggishly;
② Observation: We can conduct observation with the naked eye to detect whether there are issues such as color blocks or water ripples displayed on the phone screen;
In other words, if the touch is insensitive and there is no image displayed on the screen, it indicates that the outer screen is damaged; whereas if the touch is normal but there are issues such as color blocks or water ripples on the screen, it indicates that the inner screen is damaged.
