What is a smartphone display made of❓
Part 1. ✅
The main part of any modern smartphone is its display.
Manufacturers pay almost the greatest attention to this module, because the perception of the device by the user depends on the quality of the picture and the responsiveness of the sensor.
To better understand how technologically advanced and complex the module is on the front of our smartphones, let's see what it consists of using the iPhone as an example.
🔵 Protective glass
The topmost layer of the display that the user interacts with. The tactile sensations of the user depend on the quality of the glass and the oleophobic coating on it. When working with the iPhone, the finger simply glides over the surface, does not stick with a quick press, and does not rest against a sharp swipe.
🔵 Layer of transparent glue
The protective glass is glued directly to the matrix. This allows you to remove the air gap and reduce the thickness of the display.
A high-quality adhesive layer will not distort colors, prevent dust from getting under the glass and securely hold the top layer even during the most active use.
When replacing glass, a low-quality adhesive layer can be used, which will change its color over time, begin to distort the picture or let dust particles through.
🔵 Touchpad
It is also called a touchscreen or simply a sensor. Responsible for recognizing user clicks.
The original element is made of a thin layer of glass and allows you to determine the place of pressing with an accuracy of up to a millimeter. At the same time, the sensor has support for multi-touch technology. This element suffers when falling much less frequently than protective glass.
🔵 Polarizing filter
A special layer that makes the image of the matrix visible to the human eye. Without it, we would not be able to see anything on the screen at all.
