Environmental requirements

Flame retardants

Flame retardants are present in printed circuit boards, cables, wires, casings and housings. Their purpose is to prevent, or at least to delay the spread of fire. Up to 30% of the plastic in a computer casing can consist of flame retardant substances. Most flame retardants contain bromine or chloride, and those flame retardants are chemically related to another group of environmental toxins, PCBs. Both the flame retardants containing bromine or chloride and the PCBs are suspected of giving rise to severe health effects, including reproductive damage in fish-eating birds and mammals, due to the bio-accumulative* processes. Flame retardants have been found in human blood and researchers fear that disturbances in foetus development may occur.

The relevant TCO'99 demand requires that plastic components weighing more than 25 grams must not contain flame retardants with organically bound bromine or chlorine. Flame retardants are allowed in the printed circuit boards since no substitutes are available.

Cadmium**

Cadmium is present in rechargeable batteries and in the colour-generating layers of certain computer displays. Cadmium damages the nervous system and is toxic in high doses. The relevant TCO'99 requirement states that batteries, the colour-generating layers of display screens and the electrical or electronics components must not contain any cadmium.

Mercury**

Mercury is sometimes found in batteries, relays and switches. It damages the nervous system and is toxic in high doses. The relevant TCO'99 requirement states that batteries may not contain any mercury. It also demands that mercury is not present in any of the electrical or electronics components associated with the labelled unit. There is however one exception. Mercury is, for the time being, permitted in the back light system of flat panel monitors as today there is no commercially available alternative. TCO aims on removing this exception when a Mercury free alternative is available.

CFCs (freons)

The relevant TCO'99 requirement states that neither CFCs nor HCFCs may be used during the manufacture and assembly of the product. CFCs (freons) are sometimes used for washing printed circuit boards. CFCs break down ozone and thereby damage the ozone layer in the stratosphere, causing increased reception on earth of ultraviolet light with e.g. increased risks of skin cancer (malignant melanoma) as a consequence.

Lead**

Lead can be found in picture tubes, display screens, solders and capacitors. Lead damages the nervous system and in higher doses, causes lead poisoning. The relevant TCO'99 requirement permits the inclusion of lead since no replacement has yet been developed.

*Bio-accumulative is defined as substances which accumulate within living organisms.

**Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.

181B, 171S, 171B specifications

The Samsung 171B, 171S, and 181B are part of Samsung's legacy of innovative monitors that combine performance, sleek design, and user-friendly features. Targeted primarily for businesses and home office usage, these monitors exhibit a range of technological advancements suited for different needs.

The Samsung 171B is a 17-inch LCD monitor known for its clear and vibrant display quality. It utilizes a 1280x1024 resolution, providing users with sharp images and precise color representation. The panel employs a fast response time, allowing for fluid motion and reducing ghosting in fast-paced applications. The monitor’s bright luminance and high contrast ratio contribute to an impressive visual experience, making it suitable for tasks that require finely detailed graphics. With a slim bezel design, the 171B maximizes screen real estate while minimizing desktop clutter.

Similarly, the Samsung 171S displays a 17-inch screen but focuses more on energy efficiency and eco-friendliness. It is equipped with Samsung’s EcoLight technology, which optimizes power consumption without compromising performance, appealing to environmentally conscious users. The monitor also provides excellent viewing angles, allowing multiple users to view content simultaneously without significant color distortion. Its versatile connectivity options include VGA and DVI ports, ensuring compatibility with various devices.

The Samsung 181B takes things a step further with an 18.1-inch display, providing more screen space for multitasking and productivity. This model also features a 1280x1024 resolution, ensuring that text and images remain sharp and clear. The 181B is designed with a slim profile and an adjustable stand, allowing users to modify the height and orientation for ergonomic comfort. Additionally, it comes with Samsung’s MagicBright technology, which automatically adjusts the screen settings according to the environment and content, ensuring optimal viewing conditions.

All three monitors are designed with durability in mind, featuring long-lasting LED backlighting and robust construction. They are also compliant with various environmental standards, promoting a sustainable approach to technology. With their blend of advanced features and user-focused design, the Samsung 171B, 171S, and 181B monitors exemplify reliability and performance that cater to both professional and personal needs.
