LCD Monitor Quality and Pixel Policy
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

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.
English 43
Regulatory Information
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:

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:**
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:**
Mercury is sometimes found in batteries, relays and switches. It
damages the nervous system and is toxic in high doses.
The relevant TCO ‘95 requirement states that batteries may not
contain more than 25 ppm (parts per million) of mercury. The
relevant TCO '99 requirement states that batteries may not contain
any mercury.
English 45
Regulatory Information
Both TCO ‘95 and TCO ‘99 also demand 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 ‘95 and 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.
