Probing the Structure and Different Phone LCD Parts

Usually, cell phones today come with LCD screens, and most of them support touchscreen technology.

If you are interested in the functionality of these screens and troubleshooting easily, it is crucial that you first learn about the different Phone LCD Parts and understand the structure nicely.

The Different Layers

There are different layers of materials that make an LCD screen. All these layers and Phone LCD Parts work in unison to produce the images that you see on your phone’s screen.

• The first layer: This is the cover glass that protects your phone screen from developing scratches as well as the underlying layers from damage. It is also referred to as the touch sensor, provided the screen supports touch technology.

• The second layer: The layer underlying the first is called the touchscreen controller or digitalizer. The main purpose of these Phone LCD Parts is to sense the touch inputs of the users. It also converts them into digital signals so that the phone can respond to your inputs correctly.

• The third layer: The following layer is the display or the mobile display. Ideally, this is the specific LCD part that first receives the touch inputs received by the digitalizer. It then creates the image. This is a complex process where the polarized light is manipulated while it passes through an extensive number of liquid crystals. This, eventually, creates the image you see.

• The final layer: The last of all Phone LCD Parts under the LCD is the backlight. It illuminates the mobile screen. You can adjust the brightness level according to your preference as well as the colour and contrast.

The Varied Structure

• The digitalizer: These can be of two types, namely, resistive and capacitive, where the former functions on the basis of the electrical charge created by the stylus or the finger of the users, and the latter responds by detecting the pressure points.

• The LCD screen: There is an LCD screen in between two glass panels, a front and a rear polarizer. When a pixel or a small square of the screen experiences an electric charge, the alignment of the liquid crystals in that region is changed. This disallows the light from passing from the backlight to the front polarizer. This creates lightness or darkness in the image.

• The backlight LED: Typically, there is a wide range of light-emitting diodes (LEDs) that illuminate the backlight to allow you to see the text on the image on the screen, even in low-lit conditions.

• The integrated circuit: This is also referred to as the driver IC. The main purpose of this IC is to offer the memory and processor of the phone with a display panel interface. A wide range of processor or memory commands are handled by this IC to convert them into signals. These digital signals are then interpreted by the LCD screen, which eventually creates the image on the screen of your mobile phone.

Conclusion

There are different components and layers fused that make the LCD screen of your phone a complex device. Understanding them will help you detect the issues and the cause and buy the right parts for repair or replacement.
