The provided document is an End-of-Life Disassembly Instructions manual for an HP 22er 21.5-inch Display. This document is primarily intended for end-of-life recyclers or treatment facilities, offering guidance on how to disassemble the product to remove components and materials that require selective treatment as per EU directive 2002/96/EC (Waste Electrical and Electronic Equipment - WEEE).

Function Description

The HP 22er 21.5-inch Display is a monitor designed for visual output, likely for use with computers or other video sources. As a display, its primary function is to render images and video content for user interaction and consumption. The "21.5-inch" in its name refers to the diagonal screen size, indicating a moderately sized display suitable for various applications, from office work to home entertainment. The "22er" designation is a specific model identifier within HP's product line, suggesting a particular design aesthetic or feature set.

Important Technical Specifications

While the document doesn't explicitly list all technical specifications like resolution, refresh rate, or panel type, it does provide crucial information regarding its internal components and materials, which are relevant for its end-of-life management.

Key components and materials identified for selective treatment include:

Printed Circuit Boards (PCB) or Printed Circuit Assemblies (PCA): The display contains two PCBs/PCAs, each with a surface area greater than 10 sq cm. These are essential for the display's electronic operations, including power management, signal processing, and control.
Batteries: The document states that the display contains zero batteries of any type (standard alkaline, lithium coin, or button style). This is a positive environmental note, as batteries often contain hazardous materials.
Mercury-containing components: The display contains zero mercury-containing components, such as mercury in lamps, display backlights, scanner lamps, or switches. This is significant as mercury is a highly toxic substance, and its absence simplifies recycling and reduces environmental risk.
Liquid Crystal Displays (LCD): The display features one LCD with a surface area greater than 100 sq cm. This is the core visual component of the monitor. The note specifies that it includes background illuminated displays with gas discharge lamps, which is an important detail for recycling, although the absence of mercury-containing components suggests that these lamps might not be traditional CCFLs (Cold Cathode Fluorescent Lamps) that typically contain mercury. However, the presence of "gas discharge lamps" still warrants careful handling.
Cathode Ray Tubes (CRT): The display contains zero CRTs, confirming it is a modern flat-panel display rather than an older, bulkier CRT monitor.
Capacitors / condensers (Containing PCB/PCT): The display contains zero capacitors/condensers with PCB/PCT. This is another positive environmental aspect, as PCBs (Polychlorinated Biphenyls) and PCTs (Polychlorinated Terphenyls) are persistent organic pollutants.
Electrolytic Capacitors / Condensers: The display contains zero electrolytic capacitors/condensers measuring greater than 2.5 cm in diameter or height. These larger capacitors can sometimes contain hazardous substances or require specific handling due to their energy storage capacity.
External electrical cables and cords: The display includes three external electrical cables and cords. These are necessary for power supply and video input.
Gas Discharge Lamps: The display contains zero gas discharge lamps as a separate item, which might seem contradictory to the LCD description. This could imply that the gas discharge lamps are integrated within the LCD unit and not considered a separate component for selective treatment in this specific categorization, or it might refer to a different type of gas discharge lamp not used in the backlight.
Plastics containing Brominated Flame Retardants (BFRs): The display contains zero plastics with BFRs weighing over 25 grams (excluding PCBs or PCAs). BFRs are often used in electronics to prevent fire but can be environmentally problematic. Their absence is a positive environmental characteristic.
Components and parts containing toner and ink: The display contains zero such components, as expected for a monitor.
Components and waste containing asbestos: The display contains zero asbestos, which is a hazardous material.
Components, parts and materials containing refractory ceramic fibers: The display contains zero refractory ceramic fibers.
Components, parts and materials containing radioactive substances: The display contains zero radioactive substances.

Usage Features

As a display, the HP 22er is designed for straightforward visual output. While the manual doesn't detail user-facing features like input ports (HDMI, DisplayPort, VGA), on-screen display (OSD) menus, or ergonomic adjustments (tilt, swivel, height), the disassembly instructions provide some clues. The presence of "external electrical cables and cords" implies standard power and video input connections. The "Quick release Base stand" suggests an easy setup and potential for wall mounting or alternative stand use. The mention of "main board and shielding" indicates a standard electronic architecture for a modern monitor.

Maintenance Features

The document is not a user manual but a disassembly guide, so it doesn't describe typical user maintenance. However, the detailed steps for disassembly are crucial for end-of-life maintenance, specifically recycling and proper disposal. The instructions highlight the ease of separating key components:

Base Stand Removal: A "white button" mechanism allows for quick release of the base stand, followed by a screw for complete separation. This indicates a user-friendly design for initial setup or potential replacement/storage of the stand.
Rear Cover Removal: Screws secure the rear cover, which can then be carefully detached. This step grants access to internal components.
Internal Component Access: Once the rear cover is off, the "rear cover supporter" and other materials can be removed, leading to the main board and shielding.
LVDS/LED FFCs Disconnection: The Low-Voltage Differential Signaling (LVDS) and LED Flexible Flat Cables (FFCs) need to be pulled out to separate the base assembly from the unit. These cables transmit video signals and power to the display panel.
Shielding Separation: Screws secure the shielding from the main circuit board (CB), allowing for its removal.
Main Board Disassembly: Further screws need to be stripped to fully release the main board.
Material Segregation: The final step emphasizes releasing all materials and putting some by ESD (Electrostatic Discharge) protection, which is critical for handling sensitive electronic components during recycling to prevent damage or further contamination.

The tools required for disassembly are standard: a PH2 plum flower head screwdriver, a regular screwdriver, and an M5 hex nut screwdriver. This suggests that the design allows for relatively straightforward manual disassembly using common tools, which is beneficial for recycling operations. The detailed photographic instructions further aid in efficient and correct component separation, ensuring that materials requiring selective treatment are properly identified and handled. This focus on ease of disassembly directly contributes to the maintainability and recyclability of the product at the end of its life cycle.
