Water is a liquid crystal “natural enemy”, so do not let any thing with the water into LCD. In

addition to avoiding the above said, do not drink in the computer side of things, we must pay

attention not to the machine stored in damp, moisture will seriously damage the components within the

liquid crystal display;LCD Monitor in the winter and summer, and out of a heating or air-conditioned room The

temperature difference will lead to “condensation” occurs, the user at this time to the LCD power

would result in liquid crystal electrode corrosion, causing permanent damage. First of all, is to be

taken to avoid this from happening, at least not in general temperature is greater than 10 ℃ / 10

min; Once this happens, do not panic, but if found in the boot screen before the mist the surface with

a soft cloth gently rub on it, and then boot. If water has entered the LCD, as long as the LCD side in

warmer areas (of course can not be grilled over the fire), such as table lamps, will gradually

evaporate the water inside can be a. Touch Screen LCD Monitor If it is the rainy season, even without using a notebook, we have

regularly switched on, the machine running for some time to disperse the tidal heating component, and

Absolute coordinate system
Touch screen is an absolute coordinate system, which directly point to the election

which, with the mouse such essential difference between the relative positioning system is a

place of intuition. Touch Screen TFT LCD Monitor Absolute coordinate system characterized by positioning coordinates of

each coordinate with the previous orientation has nothing to do, touch screen is a

physically independent positioning system coordinates of each touch screen data through

calibration to the coordinates, so that requires The coordinates of the touch screen no

matter what circumstances, with a bit of output data is stable, if unstable, this touch

screen can not guarantee absolute coordinate positioning.

In this paper, resistive touch screen and touch screen controller ADS7846 touch screen and

its controller as an example describes the principle and to an application example shows how

to use touch screen and its controller for embedded systems constitute the input system.

Touch screen input system consists of touch screen, touch screen controller and the micro-

controller, composed of three parts. global-e-world Figure 1 shows a practical touch-screen input system,

the system uses four-wire resistive touch screen touch screen, touch screen controller uses

TI (BB) the company’s ADS7846.

Touchscreen
Touch-screen attached to the display surface, compatible with the display to use, if we can

measure the touch point coordinates on the screen, you can display the corresponding

coordinates of points according to the display of the content or icons were informed of the

intention of touching. Touch screen can be divided into five categories according to their

technical principles: vector pressure sensing type, resistive, capacitive, infrared type,

surface acoustic wave type, Touch Screen LCD Monitor in which resistive touch screen in embedded systems using the

more. Resistive touch screen is a four-layer composite film of a transparent screen (Figure

2), the bottom is a glass or plexiglass composition of grass-roots level, the top is a layer

of the outer surface hardening treatment to smooth and scratch-resistant plastic layer, the

middle two – metal conductive layer, respectively, at the grassroots level and plastic layer

on the surface between the two conductive layer separation point of transparency in many of

the small separated them. 7″ Touch Screen LCD Monitor When the finger touch screen, the two conductive layer in contact

with touch-point.

LCD screen is a precious component, if not dirty, then you can use the soft wool and gently brush Shan Shan 1, it is recommended to use ordinary make-up brush, this brush hair texture is very soft and will not scratch the screen, so it is easier to buy, if no can also try to use washing balls blew the ears. If it is dirty, you can use a clean cotton cloth of fine to be careful when cleaning the bathroom clean, attention must not use any chemical cleaning LCD screen! Sometimes, you may encounter some very stubborn stains, this time would be for a professional of – SONY LCD screen Chupin special cleaning agent KK-LC3! 7 Inch Touch Screen LCD This LCD stain killer course, the prices cheap, a vial is necessary to RMB 150 or so, the effect of natural doubt. Actually, we can consider the use of soft and smooth cotton or chamois glasses cloth dipped in clean water to wipe a small amount, the effect has no professional person so perfect, but the win in the cheap. Friendly reminder: wipe must be shut down state, and the amount of detergent or water must not be too much.

leaving Zhang useful tissue
Do not know if you noticed there is no, the new machines purchased before Kaifeng between the keyboard and LCD screen, there will be a separate tissue. Otherwise, when combined on a notebook computer, the keyboard and LCD screen may produce friction, resulting in Huaping situation. Some ideas ahead of books to address this problem have their own methods, such as SHARP’s UM series machines using a novel keyboard lift technology, when combined on a notebook computer, the keyboard will automatically drop 3MM.7 Inch Touch screen VGA Monitor And some books provides an LCD protection cover. But for other notebook computer users, to retain the affiliation of new tissue machine shop on the keyboard is the most effective approach.

demolition is not our work
“To avoid electric shock, do not open the rear cover on their own. For service, please contact with professional or authorized.” This phrase is very familiar, right? It is these, including many electronic products including laptop insert of the classic statement. In fact, the same as with other electronic products, LCD-house will produce a high voltage, privately apart to be very dangerous.7 Inch Touch screen Monitor Therefore, never attempt to demolish LCD, this is not explored and it-yourself questions. If you have favorite books of the LCD screen have any questions, or to the professionals to be demolished bar!
Unconsciously so much maintenance that note, I believe you on how to maintain and safeguard their beloved notebook LCD display already have a clearer concept. I hope you precious books of the “face” can be open-minded care of you every day to give you a good mood.

In particular, for many gamers, will want to be able to anytime, anywhere, “even” one of the users, and more expect to have a laptop and desktop display the same performance. Is precisely because of this, a lot of friends in the purchase when the notebook will be the selection of those who stubbornly high-end integrated graphics chip models, including processors, including the neglect of the other configurations.Touch Screen LCD Monitor

Significantly better performance is left alone to comment on how to buy gaming notebook
Core 2 Duo processor features

From the NAPA Refresh era, notebook graphics cards will have a larger part of the development, particularly in the NVIDIA and ATi’s were introduced with the GeForce Go 7000 Series Mobile Radeon X1000 series, the notebook’s display performance difference with the desktop not far away. On the desktop able to run very smooth 3D gaming in a notebook can run the same well, at least in the editor’s eyes, with the laptop playing “World of Warcraft,” “Neverwinter Nights 2″, “Need for Speed” so the game a few, while the contrast of the notebook earlier, this leap is inconceivable.

A true business notebook computers used not only to look simple and inexpensive, its more important is the security, and now many claim to be business-class notebook flagship machine, or the best business partner, but their safety is make business difficult for consumers to pay. 7″ Touch Screen LCD Monitor The Hewlett-Packard on the sights on this issue in time the market launch of this NX6330,

Used laptop fingerprint recognition friend should have this experience, when you register to the laptop’s finger injury fingerprint recognition, fingerprints have been destroyed, then it is likely to be opened within a short time with this fingers the computer, and For home users, and nothing, but if those business users, it means that the time and opportunity as well as monetary losses. But this is a Hewlett-Packard NX6330 uses biometric fingerprint reader, direct penetration to the dermis layer scanning, and can be effectively recorded more than 30 fingerprints, even if your fingers damaged, as long as no damage to the dermis layer, or you can open the computer, Even if the damage to the dermis layer, multi-fingerprint computer memory, or you can open the computer. 8″ Touch Screen LCD Monitor This is the fingerprint recognition part, also through the HP official said that the more mature technology, fingerprint identification devices are now in a multi-model, the price of models as standard-ups, the future is expected to become HP’s standard configuration, perfect to bring to consumers the safety of experience.
