Industrial monitor is introduced
Industrial display is used in industry control process or equipment.It with the civil or commercial display is the main difference between the shell design generally adopts the design of all steel panel is divided into ordinary iron plate, stainless iron, stainless steel, aluminum panel and so on different material.Industrial monitor with IP protection grade * * said the former one is dustproof level, after one is waterproof.Dust up to 6 grade, waterproof up to 8.
Industrial classification of display
1. Open type industrial displays
Industrial display is no surface box shell, only inside, most of the customer's application mainly in the equipment and small size has beautiful shell, there is no too much space to install the general display, such as ATM, POS, etc., are usually installed in the internal customer equipment.
2. The embedded industrial displays
Embedded industrial monitor as the name suggests, he must be embedded in the customer's products, the customer's product to have a large control cabinet, we embedded industrial display is the left panel, the rest are embedded in the equipment to customers, with a hook behind (large control cabinet as long as according to our embedded monitor installation drawing hole open a generous hole size) elsewhere without opening any mounting holes.
3. The rack type industrial displays
In general frame of industrial monitor is such as: installed on the 19 inch rack, so he is the width of the standard 19 inch, mounting holes according to the standard number of U.Commonly used in telecommunications, power, such as large cabinets used in large server.
4. The inversion type industrial displays
Simple said is reverse in the customer's cabinet and equipment installation, is within the client machine equipment installation industrial monitors, industrial monitors are different with open it shell power, its edges and the chassis with customer overlap, generally used in large and medium-sized equipment, such as electric power, machinery, medical industries.
5. Wall hung industrial displays
Characteristic is that it can hang up, just hang on the wall, most of them are installed on the customer's equipment, it can adjust the Angle with the requirements of our customers, with the right arm installation, he can stay in any position at random, for users to watch, generally used for small, medium, large equipment.
How to choose and buy industrial display
One, make sure the products and engineering requirements, such as the installation structure, signal type, size, panel and LCD screen performance.
1, installation is divided into the upper frame, flip chip type, embedded, open and module.
Mounted on industrial devices such as displays used in industrial control cabinet, chassis, chassis general with U, for the unit 1 U is equal to the 44 cm.Commonly used 4 u, 6 u, 8 u, etc.
Flip chip type industrial monitors from the cabinet back flip, the front of the cabinet only display LCD display area.
Embedded industrial monitor embedded directly from the front cabinet, use the hooks on the side.
2, size
Industrial displays commonly used size of 5.6 inches and 6.4 inch, 8.4 inch, 10.4 inch, 12.1 inch, 15 ", 17 ", 19 inch, 20.1 inch.Some other size company also developed a corresponding products.Make sure the product when using industrial displays.
3, the structure of the panel
Panel generally magnesium alloy, cold-rolled plate, galvanized sheet, stainless steel plate, hot galvanized sheet, die-casting aluminum material.
4, the types of signals
The VGA and AV interface signal interface.
5, LCD display performance
Brightness: since most flat-panel displays are used in indoor environment and is about 250 ~ 300 CD/m2 brightness (nit), diagonal dimension for 15 inch LCD is the most commonly used, however, the brightness level of display used in industrial environment is unable to meet the requirements, this is because the environment light will be more strong, the brightness is very easy to exceed the brightness of the LCD backlight.Moreover, often using touch screen in the industrial environment, it also can reduce the brightness of the display, make it look darker.In the usual application place such as medical, industrial and public telephone booth, the brightness of the required to at least 450 CD/m2.
Contrast: I don't like consumer display is mainly used for direct viewing, for industrial-grade display, the user may not be the best distance or watch the ideal lighting conditions, so the higher contrast of the display is the best choice.For use in most industrial fields of 10.4 inches and 12.1 inches or 15 inch monitors, 450:1 contrast is the ideal.
Colour:
In
some industrial applications, the special color information is more
important than the text or Numbers that will measure the color of a
control on the number of the percentage of the NTSC color saturation is
very important.In the LCD products, color saturation is totally dependent on the influence of the backlight.CCF
(cold cathode jade-like stone light screen) backlight is very popular
technology, and can reach 70% and 80% of the NTSC color saturation.
Perspective:
Commercial and consumer monitors usually is designed for single use directly in front of the display.In most industrial applications, this kind of situation is very rare, for example, a physician or nurse can't stopped to watch the display directly in the process of diagnosis and treatment, they just want to know the desired data.For a large machine, directly in front of the display operation is simply not possible.For navigation of ships or aircraft, the driver is not convenient, sitting in front of the LCD directly especially when there are multiple display, they are based on different Angle facing the viewer.
Display should have a wide perspective, or considered to be "a glance to understand the content that is displayed".Consumer monitors generally cannot meet the requirements of this, this is because they use the technique of Twisted Nematic (Twisted Nematic), so the limited perspective.In order to better adapt to the industrial application and requires display has a very wide Angle of view, has now developed a perspective of up to 178 ° display technology (e.g., ASV or MVA).
Backlit life
Cold cathode fluorescent lamp (CCF) is the most commonly used in LCD backlight source.In the field of industrial applications, CCF backlight long time at least 50, 000 hours, or compared with the new brightness down to half of the time.In many consumer applications, the brightness of the backlight to half its original brightness demand only 10, 000 hours of time.
Due to consumer applications do not need to monitor work, 10, 000 hours of CCF backlight is enough life, however, in most industrial and medical applications is not the case.The life of the backlight is very low compared with the life of the LCD.People are trying to increase the life span of the backlight to two times, but in most industrial applications, the minimum 50, 000 hours is considered to be the life of a CCF backlight standard of life.
Second, choose manufacturers
Imports: SIEMENS (SIEMENS), Schneider (Schneider), plouffe Proface, hundred F B + F, grind degrees;
Beijing: caijing, crystal and the more the world, Martin sharp, novy century, three strange extension, macro goodsky wins, we have pleasure in progress
Shanghai: da jia, lang farce electronics
Guangzhou: guangzhou most, brand mix.
Domestic while engaging in industrial monitor business is more, but specializing in the production of industrial display less.YouYan China, evoc, Jin Ling one, and caijing, da jia, lang farce, etc.
Three, price negotiation
Industrial display LCD screen and industrial components, later there are a lot of quality inspection, finished product need to be entered in an airtight room damp baking machine for 48 hours.So the cost and selling price is higher than general civil displays a lot.
The grind degrees, evoc price and performance belongs to high-grade, price at around $4000.Jin Ling norda jia, lang price about 3000, gen caijing price about 2000.
Fourth, after-sale protection
Industrial display the general is one year warranty.
