Touch LCD Monitor from a positive perspective, no significant difference between the normal view, rear view, then more than ordinary display of a signal line, that is, the signal line connecting the touch screen. Normal display when in use, usually do not need special drivers, while the touch screen when in use, a dedicated driver touching the screen must have, otherwise it can not access the operation of rights.
In fact, international brands 3M ELO Gvision, etc., but the price is relatively high, the land quality is a little low, but the price is relatively flat LCD monitor low, but in total quite good, such as benefits and other domestic Chinese HY-TOUCH, if the continued high quality but cost effective if the national brand is a good choice!
are first as a professional touch-screen LCD manufacturers, mold, and general institutional design, the layout of electronic components, touch screens in a unique way shall take Gvision products and much more for their own development and construction of the A / D design of the entire body, but also for the touch screen on a professional design, unique design with several pieces of iron as a solid rather than simply with tape and paste can be fixed. Secondly, the touch screen work, the general reserve of a diploma from the space, you can install other touch screen compatible. Third, the professional work of stable touch screen, shake not only Contacts particular contact with another key, indicating the machine more stable. Fourth, the touch-screen machine quality assurance. Thus, the total return is more reliable. The display button more general application in the high end touch screen and local, such as POS systems upscale restaurant, industrial, medical system, conference room and so on.

The first thing to do is to consider carefully whether the source computer, it interfering electromagnetic devices, and replace a video card, or receipt of other computers monitor, graphics card not confirm even the problem, then set the refresh rate. If you exclude the above-mentioned reasons, it is possible that the quality problem of the LCD monitor, such as poor thermal stability issues. There is a ripple LCD problems with water quality more frequently, they can not solve, the proposed replacement or repair as quickly as possible.

Because

LCD and CRT displays different principle, it is a direct correspondence between the pixels. Work among the best resolution of the LCD screen for graphic display of the analog signal processing, processing of certain address (the pixels on the screen of the absolute address) of the signal indicator, then the LCD display directly to the display signal to the corresponding pixel on the transmission pipe, some prefer to write with memory addressing and. So the resolution LCD screen is not arbitrary, but fixed traditional CRT monitors support for the resolution of the most flexible. LCD only supports so-called “effective resolution” and the only real solution to show the best picture. When connected to a different decision than the actual resolution, usually by increasing or decreasing set of possibilities screen, the display will stay the same, more than some of the black handle. Such as liquid crystal displays, which in low resolution 800 * 600 pixels, if the if the display is always a correspondence with the screen, then it may be in the middle of the screen narrow the focus of this * 800 600 pixels are displayed, although image is always clear, but the screen is too small, not only unpleasant, but is also expensive LCD an enormous waste. Another interpolation method can also be used, the full screen resolution, but this time appears impaired. In addition to the LCD refresh rate settings and image quality to some degree. Friends according to their actual situation may be appropriate to the refresh rate, normally set at 60 Hz or higher.

three deficiencies: the screen brightness and contrast are not very good. How should the liquid crystal molecules are neither light therefore rely on external light source for LCD illuminator. In general, the 140 lumens per square meter is sufficient. There are some manufacturers of norms and standards of the practical parameters, it is a gap
disadvantage 4. LCD “dead pixel” problem. LCD-glass materials are installed, it is easy to break through, each pixel is very low, often lead to misbehavior of individual pixels TFT, commonly called “dead pixels”, which is beyond repair, you do not change the entire screen, order while the price is often very expensive to replace
five deficiencies. a limited life. In contrast to the LCD screen in a sustainable manner. Two to three years is generally considered the normal life span, and thus when buying two or three years is ready to replace the ad again.
In general, traditional CRTs in color and fast display of images and other advantages are obvious, while the LCD screen in the form and no radiation, no flicker of services very unusual. Beet have to buy all the love in the end this type of display products should be fit your specific needs.
