Now, the low-temperature polysilicon technology, reflective liquid crystal materials have entered the application phase, the development of LCD will enter a new era. Continuous development in the LCD, while the other flat-panel displays are progressive, the plasma display panel (PDP), electroluminescent display array (FED) and the light-emitting polymer displays (LEP) technology will be launched in the future the new flat panel displays wave. One, the most noteworthy and promising is the field induced monitors, LCD monitors it has many much better performance ... ... but you can conclude, LCD display technology into a new era, as another branch of the force display products, they will likely replace CRT monitors .

advanced the "continuous crystalline silicon material industry" LCD display
In a number of LCD products, the dynamic movie viewing screen will appear when the delay phenomenon, which is due to the liquid crystal display screen pixel response time caused by insufficient appear. In order to improve pixel response speed, the new LCD technology uses the most advanced Si TFT liquid crystal display mode with LCD screen than the old 600 times faster pixel response rate, the effect is really quite different. Advanced "continuous crystalline silicon material industry," technology is the use of special manufacturing method, the original transparent non-crystalline silicon electrodes in the order of 600 times the normal rate of speed to move, thus greatly accelerating the reaction rate pixel LCD screen to reduce the delay phenomenon screen appears.

Now, the LCD monitor is becoming more popular, but many people in the LCD screen clean There are still some misunderstandings.

LCD screen surface than regular CRT monitors to be much more vulnerable

The best choice for a special screen cleaning cloth. Screen cleaning
cloth that has good water absorption and good cleaning power, dirt will
be easily absorbed into the cloth, and wipe again and again does not
re-stick to the screen, dust particles will not scratch the LCD screen.

Ability to clean water? Water clean-up screen is theoretically no
problem, but must put water on the cloth wring use, the state can be
slightly damp, or wipe the excess water when the flow is easy to
monitor the gap in the border, could cause the screen colors not
uniform, that is Huaping.

Rubbing alcohol can be used to screen it? Yes, but not a large amount,
the number of not more than, the time and do not use too much force,
preferably with anhydrous alcohol, so it would not be corrosive to the
screen. In fact, so far is simply the best way is with a clean screen
cloth and special cleaning agent, disconnect the power when cleaning.

How to clean LCD case? Many friends will choose to use washing powder
and wipes to clean the LCD Monitor
cover, this approach is not scientific. I
recommend using the toothpaste, squeeze a little on the cloth, wipe the
display case of stubborn stains, to ensure immediate.

Body thin, space-saving

And more cumbersome than CRT monitors, LCD monitors as long as the former one-third of the space.

Power, does not produce heat

It belongs to low-power products that can be completely heat (some of
the major electricity and heat present in the backlight lamp or LED),
and CRT monitors, because imaging technology inevitably leads to high
temperature.

No radiation, the benefits of health

LCD completely without radiation, which for all people who work at the computer is a boon.

Soft focus pictures do not hurt

Is different from CRT technology, LCD screen does not flicker, can
reduce the display of the eye injury, eye fatigue is not easy.

LCD green, it's energy consumption compared to traditional CRT is
literally too small (17''200W power probably less than); for the recent
subject of growing attention to the noise pollution people have no
chance with it, because it their work characteristics determines that
it will not produce noise (one side for those who like to use a
computer, while the rhythmic beat of the user display the noise, here
not to be considered); LCD display also has the benefit that is lower
than heat, prolonged use will not be baking hot feeling that is
incomparable previous display, the previous display, but valuable,
especially in summer, home air conditioning, fans had to cool down its
service to it. The atmosphere using the liquid crystal display
virtually down the temperature, but also to prevent the increasingly
contribute to atmospheric warming. At the same time reduce emissions,
reduce environmental pollution. Of course, environmental protection,
not less radiation to this index, although we can not say no radiation
on the liquid crystal display, but large relative to the radiation CRT,
as well as everyday household appliances radiation, the liquid crystal
display so little radiation is simply negligible .

Now the times are actually analog era, the era of the future from the
current development trend is the digital age. Display intelligent
operation, digital control, digital display is a necessary condition
for future display. As the digital era, digital technology will
completely replace analog technology, LCD will soon replace the
existing analog CRT monitors.

But from another angle LCD digital interface is not very common, far to
the applications. In theory, the liquid crystal display is a pure
digital device, the host computer should also be used to connect
digital interface, digital interface, the advantages of self-evident.
First, the module can reduce the signal loss during the conversion
process and interference; reduce the conversion of the corresponding
circuits and components; second clock frequency is not required, the
adjustment vector.



However, the market most of the LCD interface is analog interface, the
existence of signals susceptible to interference, the display needs to
join the ADC internal circuitry, can not be upgraded to a digital
interface and so on. And, in order to avoid the appearance of
flickering pixels, must be the clock frequency, vector and analog
signal exactly.

In addition, the liquid crystal display digital interface has not yet
formed a unified standard, with a digital output video card in the
market are rare. Thus, the key advantage of LCD is very difficult to
bring into full play.

This problem may not be well understood, we explain it examples. Used
LCD monitors know that LCD is easy to produce image smearing.

LCD response time is a special target. LCD monitor response time refers
to the input signal of each pixel response rate, response time, shows
the campaign does not produce images when the screen trailing
phenomenon. This is playing games, watching video when fast action is
important. Fast enough response time to ensure the continuity of the
screen. Present, there is a general liquid crystal display, response
time is quite different than before the break, usually around 40ms. But
as the technology development of LCD and CRT increasing this gap is
gradually being up on a liquid crystal display response time has been
reduced to 5ms.

Judging from the shape the appearance of light and ultra-thin LCD
display, compared with the conventional spherical display, its
thickness, size is only half of CRT monitors (such as acer's FP581, its
thickness is less than ordinary people feel that CRT displays 1 / 5 ),
greatly reducing the floor space.

Hong Kong and Tokyo is the world's regions with the highest penetration
rate of LCD monitors, LCD monitor shipments last year accounted for
Hong Kong to monitor the total volume of Qi Cheng. We look at areas
with high prevalence LCD easy to see that most of these places are more
prosperous, more crowded, relatively high standard of living, and
office buildings, where the financial skyscrapers. Is the high cost of
land in these places used to be. Display space savings is much higher
than land prices and CRT monitors LCD monitors the difference. Now some
cities in Mainland China is also busy regional trend towards this
direction.

This question was to ask you for your display purposes. As we all know,
since liquid crystal molecules are neither light, therefore, need to
rely on external light source LCD auxiliary light. In general, 140
lumens per square meter is enough. Some manufacturers standards and
practical standards for the parameters there is a gap. Here to explain
is that some small-sized liquid crystal displays in the past were
mainly used in notebook computers, two-light adjustment, so they are
not very good brightness and contrast. But now the mainstream of the
desktop version of the LCD display brightness can generally be up to
250 lumens to 400 lumens, has begun to move closer to the level of a
CRT.

For most people, if the CRT and LCD display together, you can more
easily distinguish between LCD and CRT monitors general brightness and
contrast and color saturation are different, but for general use, this
a little bit of difference will not affect your work.

But for the professional art work and other requirements for accurate
color VGA Monitor
can not fully meet the requirements of their work.

The
CRT is completely different, CRT works by the filament, cathode,
control grid electron gun component, is powered hot filament, the
cathode was excited, emitted electron flow, electron flow by a high
voltage to accelerate the internal metal layer, after Lens formation of
very fine electron beam, hit the screen, so that the fluorescent light.
Electron beam in the magnetic field produced by deflection coils, you
can control the shooting at the screen, specify the location of the
electron beam hit the screen after the formation of a luminous point, a
number of light spots can form images. RGB three-color dots of
different intensities of the electron beam was hit, it will produce a
variety of colors, by controlling the electron beam intensity and off,
you can create a variety of colorful images. General shadow mask tube
similar to sieve the internal layer of the network mask, electron beam
through the mesh to play in the triangular arrangement of fluorescent
spots, the three electron guns corresponding to the three RGB color, so
called "three shots at the three-beam" tube. Yam grating tubes (such as
Trinitron and Diamondtron) the principle is the same, but the network
of such tubes is to cover a fixed number of vertical grating formed in
the box.
