Display screens are electronic products that integrate various parts and components. The production process is complex and there are many parts and components. If one of the parts fails during use, the entire display screen may not work properly. Or, if the product structure changes, the line of accessories needs to be updated. Therefore, as a display screen manufacturer, we should not only ensure the quality of the main product, but also reserve some accessories that may be used to solve problems for customers at any time. Hot Display is such a supplier, always ready to provide customers with efficient solutions.

What are the common spare parts for display screens?

Display-related parts include various hardware components that work together to achieve the functions of the display. The following are common display parts and their brief introduction:

Display panel (LCD/LED, etc.):

• LCD (Liquid Crystal Display): Uses liquid crystal materials to change light transmittance under the action of electric field to achieve display function.

  
  

• LED (Light Emitting Diode Display): Uses LED as light source, usually used for outdoor and large display screens.

Backlight assembly:

• LED backlight: used for LCD displays, LEDs provide uniform backlight to ensure screen brightness and contrast.

  
  

• CCFL backlight (cold cathode fluorescent lamp): the backlight source of early LCD displays, which has now been gradually replaced by LED backlight.

Drive circuit:

• TFT drive circuit: used to control each pixel in the TFT-LCD panel to ensure the correct display of the image.

  
  

• Power management circuit: provides stable power output to ensure the normal operation of all parts of the display screen.

Controller:

• Display controller (Scaler): responsible for processing input signals and converting them into a format that the display can recognize and display.

  
  

• Video processing chip: used for image processing, enhancement and signal conversion to improve display quality.

Connectors and cables:

Data cable: used to transmit display data, such as LVDS, eDP, HDI, etc.

Power cable: provides power to the display and related components.

Touch screen components (if the display has touch function):

• Touch sensor: detects the user's touch position and action. Common types include capacitive and resistive touch sensors.

• Touch controller: processes the data from the touch sensor and converts it into signals that can be recognized by the device.

Protective glass:

Used to protect the display panel from external physical damage, usually made of reinforced glass (such as Gorilla Glass).

Housing and frame:

Frame: used to fix and protect the display panel and internal components, usually made of plastic or metal.

Stand: provides a structure to support and install the display to ensure the stability of the display.

These parts work together to ensure that the display can display images normally and stably and provide a good user experience. Displays of different types and uses may have different configurations and components, but the parts listed above are common key parts in display products.
