Display Board Support

Display board support encompasses the hardware, software, and associated services required to enable a display to function with a computing system. It is a broad category covering a range of technologies and components.

Material Components:

• Display Interface: The physical connection between the display and the system. Common interfaces include:
  • HDMI (High-Definition Multimedia Interface): Predominantly used for consumer electronics and modern computers. Transmits both video and audio digitally.
  • DisplayPort: A digital interface often favored in computer displays, offering high bandwidth and features like daisy-chaining.
  • VGA (Video Graphics Array): An older analog standard, still found on some legacy devices.
  • DVI (Digital Visual Interface): An older digital standard, largely superseded by HDMI and DisplayPort.
  • LVDS (Low-Voltage Differential Signaling): Commonly used in LCD panels, particularly in embedded systems and automotive displays.
  • eDP (Embedded DisplayPort): A variant of DisplayPort designed for embedded applications, offering reduced pin count and power consumption.
  • MIPI DSI (Mobile Industry Processor Interface Display Serial Interface): Used in mobile devices and small displays.
• Graphics Controller: The component responsible for generating the video signal. This can be integrated into the CPU (integrated graphics) or a dedicated GPU (Graphics Processing Unit).
• Display Drivers: Software that allows the operating system to communicate with the graphics controller and the specific display panel.
• Timing Controller (TCON): A chip within the display panel that manages the timing and sequencing of signals to the LCD or OLED pixels.
• Backlight System: Provides illumination for LCD panels. Common types include:
  • LED (Light-Emitting Diode): Most common type, offering energy efficiency and long lifespan.
  • CCFL (Cold Cathode Fluorescent Lamp): Older technology, less common due to higher power consumption and mercury content.
• Panel Technology: The core technology used to create the image.
  • LCD (Liquid Crystal Display): Most widely used type, relying on liquid crystals to modulate light. Subtypes include TN, IPS, VA.
  • OLED (Organic Light-Emitting Diode): Offers superior contrast and color accuracy, but generally more expensive.
  • LED (Light-Emitting Diode): Often refers to LED-backlit LCDs, but can also refer to direct-view LED displays.

Purpose & Function:

The primary purpose of display board support is to render visual information from a computing system onto a display device. This involves:

• Signal Conversion: Converting digital data from the CPU/GPU into a format compatible with the display interface.
• Resolution & Refresh Rate Management: Supporting various resolutions and refresh rates.
• Color Calibration: Ensuring accurate color reproduction.
• Power Management: Controlling the power supplied to the display and backlight.
• Display Control: Providing functionality for adjusting brightness, contrast, and other display settings.

Usage Scenarios:

• Desktop Computers: Connecting monitors to display graphical user interfaces, applications, and multimedia content.
• Laptops: Integrating displays and associated support circuitry into a portable form factor.
• Mobile Devices (Smartphones, Tablets): Supporting small, high-resolution displays.
• Embedded Systems: Controlling displays in industrial equipment, automotive applications, and medical devices.
• Digital Signage: Driving large-format displays for advertising and information purposes.
• Gaming: Providing high refresh rates and low latency for immersive gaming experiences.

Common Types (categorized by integration level):

• Integrated Graphics: Graphics processing built into the CPU. Offers basic display support and lower power consumption.
• Discrete Graphics Cards: Dedicated GPUs providing higher performance for gaming, professional applications, and high-resolution displays.
• Embedded Display Controllers: Specialized chips designed to manage displays in embedded systems.
• DisplayPort/HDMI Controllers: ICs that handle the physical interface and signal conversion.
• LCD Driver Boards: Complete boards that provide power, timing control, and interface for LCD panels.

Based on the provided information, “display board support” can be classified under the following HS codes:

• 8537.10.91.70: Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or the distribution of electricity, including those incorporating instruments or apparatus of chapter 90, and numerical control apparatus, other than switching apparatus of heading 8517: For a voltage not exceeding 1,000 V: Other: Other. This HS code covers boards, panels, consoles, desks, and cabinets equipped with electrical apparatus for control or distribution, potentially including display boards as part of the integrated system.

  • Chapter 85: Electrical machinery and equipment.
  • Heading 8537: Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of headings 8535 or 8536.
  • Subheading 8537.10: For a voltage not exceeding 1,000 V.
  • Further Subdivision 8537.10.91.70: Specifically for other types of boards, panels, consoles, desks, and cabinets.

• 8537.10.91.60: Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or the distribution of electricity, including those incorporating instruments or apparatus of chapter 90, and numerical control apparatus, other than switching apparatus of heading 8517: For a voltage not exceeding 1,000 V: Other: Programmable controllers. If the display board support functions as part of a programmable controller system, this HS code may be applicable.

  • Chapter 85: Electrical machinery and equipment.
  • Heading 8537: Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of headings 8535 or 8536.
  • Subheading 8537.10: For a voltage not exceeding 1,000 V.
  • Further Subdivision 8537.10.91.60: Specifically for programmable controllers.

• 8538.10.00.00: Parts suitable for use solely or principally with the apparatus of heading 8535, 8536 or 8537: Boards, panels, consoles, desks, cabinets and other bases for the goods of heading 8537, not equipped with their apparatus. If the support is a component for a board, panel, console, or cabinet of heading 8537 and is not a complete unit, this HS code applies.

  • Chapter 85: Electrical machinery and equipment.
  • Heading 8538: Parts suitable for use solely or principally with the apparatus of headings 8535, 8536 or 8537.
