LCD Monitor Quality and Pixel Policy
HP uses selected high quality panels for the manufacture of its LCD monitors. Nevertheless, the display may have cosmetic imperfections that appear as small bright or dark spots. This is not specific to HP but linked to the current state of the art of LCD manufacturing. In fact, an LCD screen is made of millions of small sub-pixels that are each turned on or off by a transistor and it is extremely difficult to manufacture millions of perfect transistors on a large surface. Therefore, no manufacturer can currently guarantee 100% defectfree panels at a reasonable price. How visible a defect is depends on its nature an location. Each pixel is made up of one red, one green and one blue sub-pixel. A defect in a sub-pixel is not very visible, and can often only be perceived against specific backgrounds. Adjacent sub-pixel defects are more visible than geographically dispersed defects. A full-pixel defect (all three R/G/B sub-pixels always on or always off) is quite visible. HP does not accept any full-pixel defects upon shipment. The vast majority of monitors do not have visible imperfections. On the other hand, HP is obliged - for the reasons outlined before - to accept the possibility of a few sub-pixel defects. HP has established clear standards for the maximum number of imperfections per panel that can be tolerated. Your display has been checked to comply with these standards. If you are interested in the technicalities you can find the details of HPs pixel policy below.
Details of HPs Pixel Policy
To identify defective pixels, the monitor should be viewed under normal operating conditions, preferably in its native resolution, and from a normal viewing distance of at least 50 cm (16 in.).

English 33

drus.fm Page 34 Wednesday, July 3, 2002 4:18 PM
Under these conditions the TFT1520 display does not have more than: a total of 10 total sub-pixel defects (of whatever nature) or 5 defective red sub-pixels or 5 defective green sub-pixels or 5 defective blue sub-pixels or No more than four pairs of adjacent defective sub-pixels i.e. no fully defective pixel.

TCO '99 (European Union Only)
Congratulations! You have just purchased a TCO '99 approved and labeled product! Your choice has provided you with a product developed for professional use. Your purchase has also contributed to reducing the burden on the environment and to the further development of environmentally adapted electronics products. This product meets the requirements for the TCO '99 scheme which provides for an international environmental and quality labeling of personal computers. The labeling scheme was developed as a joint effort by the TCO (The Swedish Confederation of Professional Employees), Svenska Naturskyddsforeningen (The Swedish Society for Nature Conservation), Statens Energimyndighet (The Swedish National Energy Administration), and SEMKO AB. The requirements cover a wide range of issues: environmental, ergonomic, usability, reduction of electric and magnetic fields, energy consumption and electrical safety. Why do we have environmentally labeled computers? In many countries, environmental labeling has become an established method for encouraging the adaptation of goods and services to the environment. The main problem, as far as computers and other electronics equipment are concerned, is that environmentally harmful substances are used both in the products and during their manufacture. Since it is not so far possible to satisfactorily recycle the majority of electronics equipment, most of these potentially damaging substances sooner or later enter nature. There are also other characteristics of a computer, such as energy consumption levels, that are important from the viewpoints of both the work (internal) and natural (external) environments. Since all methods of electricity generation have a negative effect on the environment (for example, acidic and climate-influencing emissions, radioactive waste), it is vital to save energy. Electronics equipment in offices is often left running continuously and thereby consumes a lot of energy.

What does the environmental labeling involve? The environmental demands have been developed by Svenska Naturskyddsforeningen (The Swedish Society for Nature Conservation). These demands impose restrictions on the presence and use of heavy metals, brominated and chlorinated flame retardants, CFCs (freons) and chlorinated solvents, among other things. The product must be prepared for recycling, and the manufacturer is obliged to have an environmental policy which must be adhered to in each country where the company implements its operational policy. The energy requirements include a demand that the computer and/or monitor, after a certain period of inactivity, shall reduce its power consumption to a lower level in one or more stages. The length of time to reactivate the computer shall be reasonable for the user. Below, you will find a brief summary of the environmental requirements met by this product. The complete environmental criteria document may be ordered from: TCO Development SE-Stockholm, Sweden Fax: +07 Email (Internet): development@tco.se Current information regarding TCO '99 approved and labeled products may also be obtained over the Internet, using the address: www.tco-info.com
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*1 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:*2* Cadmium is present in rechargeable batteries and in the colourgenerating 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:*2* 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 labeled unit. There is however one exception. Mercury is, for the time being, permitted in the back light system of flat panel monitors as there today 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:*2* 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.
1* Bio-accumulative is defined as substances which accumulate within living organisms. *2* Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
