What Are the Key Parts of a 2.4 Inch Customized TFT-LCD Panel Module?

Liquid Crystal Layer
The liquid crystal layer is the layer of the LCD that contains the liquid crystals. The liquid crystals are made of materials such as nematic or cholesteric.

The liquid crystals are arranged in a specific pattern. The most common patterns are twist nematic (TN), super twisted nematic (STN), and in-plane switching (IPS). The liquid crystals are aligned with the electric field and are controlled by the voltage applied to the electrodes.

 

Cover Glass
The cover glass protects the LCD from damage and provides a surface on which the user can interact with the panel.

TFT LCD Panel use two types of cover glass. Rigid cover glass is made of either soda-lime glass or Gorilla Glass. Flexible cover glass is used in some TFT LCD Panel, such as those used in mobile phones. The flexible cover glass is more resistant to breakage than rigid cover glass, making it ideal for use in portable devices.

 

Backlight Unit
The backlight is the layer of the LCD that emits light. Backlights can be made up of light-emitting diodes (LEDs), an electroluminescent panel (ELP), cold cathode fluorescent lamps (CCFLs), and hot cathode fluorescent lamps (HCFLs), or external electrode fluorescent lamps (EEFLs).

 

Touchscreen
The touchscreen is an optional part of the panel module that allows the user to interact with the panel. A touchscreen is a layer of glass that is coated with a material that is sensitive to pressure. When the user presses on the touchscreen, the pressure is registered and converted into an electrical signal.

 

Bezel
The bezel is another optional part of the panel module. It is used to protect the panel module from damage.

 

Driver IC
The driver IC is responsible for driving the TFT LCD panel. It converts digital signals into analog signals that can be used by the TFT LCD panel.

How to Maintain 2.4 Inch Customized TFT-LCD Panel?

After using the TFT liquid crystal panel for a period of time, it will be found that a layer of dust is often adsorbed on the panel, and sometimes various water stains are accidentally stuck, which greatly affects the visual effect and how to clean it.

 

Turn off the LCD power first, and remove the power cord plug and the graphics card cable plug.

 

Move the LCD to a place with better natural light so that you can see where the dust is, which is more conducive to targeted, so as to achieve a better cleaning effect.

 

No special solution or wiping cloth is needed to clean the TFT LCD screen. Water + soft lint-free cloth or cotton lint-free cloth is a good tool for cleaning the TFT LCD screen (it is also possible to remove paper towels). When cleaning, you can use a cotton lint-free cloth dipped in water and wring it a little, and then gently wipe the dust on the panel with a slightly damp and soft lint-free wet cloth (do not squeeze the panel forcefully). Wipe from one side to the other until everything is clean.

 

After cleaning the LCD screen with a damp, soft, damp cloth, use a damp cloth that has been wrung dry to clean it again. Then let the air and water on the LCD screen dry naturally in a ventilated place.

 

Avoid vibration. The LCD's LCD screen is very fragile. Avoid strong shocks and vibrations. Do not put pressure on the LCD screen or bump or squeeze it on the LCD screen back cover.

 

Prevent electromagnetic interference. Whether it is a CRT or TFT LCD panel, keep it away from objects with strong magnetic fields. The strong magnetic field around it will cause extra voltage inside the panel, which will affect the stability of the panel voltage. Being in a strong magnetic field for a long time will also cause color distortion, which will affect the panel effect and life of the LCD. Pay attention to humidity. Do not allow any moisture to enter the LCD.display.
