To say that the monitor has to start from the TV display technology. Because the monitor is actually a specific application of display technology. In 1883, the German Pavel. Nipkov invented the television scanning disk. In 1925, American Baird invented a mechanical scanning television. In 1933, the father of modern television, the Russian American scientist Zorkin successfully developed a practical photoelectric camera tube and a TV picture tube. Since then into the era of electronic television. Since the 1990s, a variety of display technology application devices have appeared on the market. Along with this, monitors of various models and functions have entered the security monitoring centers of cities, communities, office buildings, factories, and schools around the world.
The development of monitors has experienced black and white to color, flashing to no flicker, CRT (cathode ray tube) to LCD (liquid crystal) development process, each process is a qualitative leap, in this process, the function of the monitor and The performance has been greatly improved. The monitor is the display part of the surveillance system and is the standard output of the surveillance system. With the monitor display, we can view the front-end images. The monitor is simpler in function than the television but requires higher performance than the television. It is mainly reflected in the image clarity, color reproduction ability and overall stability. At present, the application of monitors is very extensive, and the types are gradually enriched. From the simple CRT monitor to the current LCD monitor, rear projection, plasma and more. They have their own strengths, LCD monitors, high definition, power saving, occupying a small space, the disadvantage is that there is patchwork stitching, now 40,42,46 inch LCD monitor stitching gap is about 20MM; rear projection Features are no seams, the disadvantage is large, power consumption, short life (usually 5000 hours to change the bulb), low brightness (middle light dark); plasma monitor has the advantage of high brightness contrast, the disadvantage is not suitable for displaying static images (Easy to cause screen burns), high power consumption, stitching seams.
At present, traditional CRT monitors still occupy about 50% of the market due to their advantages such as low price, high brightness, wide viewing angle, and long service life. However, the CRT monitor also has its own limitations, and it bears the brunt of its size. Generally, the specifications of the CRT are 14-inch, 15-inch, 21-inch, 25-inch, and 29-inch. Generally, there are few 29-inch or more under 14 inches. See you next. It is well known that the larger the CTR size, the greater the size and weight will be. The 29-inch CRT will weigh about 60 kg. However, the current development direction of the monitor market is "big and thin." This highlights the value of LCD monitors. The larger size, smaller size and smaller size of LCD monitors have made it a challenge to challenge the dominance of the CTR monitor market. The size of LCD monitors on the market is as small as 6.4 inches and as large as 130 inches are common. It has been widely used in petroleum, chemical industry, public security, finance, schools, transportation, energy, power, water conservancy, geology, metallurgy, telecommunications, medical, military and other fields.
The production and application of the major LCD monitors in China has not been scaled. With the decline in the price of LCD panels, the recognition of LCD monitors has increased. In 2009, businesses began to pay attention to this product, and manufacturers concentrated in Guangdong, Beijing and other places. .
At present, the domestic LCD monitors have become more and more sophisticated in security monitoring. The Pingan City project is also in constant demand. As a company that has been engaged in the research and development of LCD products for many years, Beijing Xinkehua Technology Co., Ltd., since the company was founded in 2003, According to the needs of customers customized LCD monitor products, from industrial applications 6.4 inches, 8.4 inches, 10.4 inches, 12.1 inches gradually expanded to 15.1 inches, 17.1 inches until the maximum size of the LCD panel 100 inches, forming a series of four hundred These products integrate industrial-grade display technologies that they are focused on and excel at, and have improved the quality and environmental adaptability of LCD monitors. In the world's first city, Weiwu Expressway, Changzhou City Government, Anqing Public Security Bureau, Anyang Public Security Bureau and other projects have experienced long-time, high-intensity applications.
Due to the increasing use of LCD panels, the price of LCD TVs in the market continues to decline, so the idea of ​​using LCD TVs instead of LCD monitors has emerged. Some people have done so. Can LCD TVs replace LCD monitors? This problem has become a confusion for system integrators. In fact, it is simple, from the difference between LCD monitors and LCD TVs.
First of all, the application of these two products is different, the requirements are also different, LCD TVs usually watch fast-changing motion picture, the image processing ability of the still picture is poor, and the LCD monitor mainly monitors the still pictures. , so the LCD monitor on the image processing is more professional, professional LCD monitor with bandwidth compensation and lifting circuit, video bandwidth up to 20M, so that sharpness is greatly improved, professional 3D digital comb filter, enhanced brightness, chroma digital noise reduction Processing capacity, enhanced motion detection capabilities, significantly improve the smoothness of the edge of the moving image, greatly improved the level of the screen, can better show the details, make the screen more delicate and natural;
Secondly, LCD monitors often require 24 hours a day and 365 days of continuous power-on use each year to form a closed-circuit monitoring system. Televisions usually only work for a few hours each day. This imposes higher requirements on power supplies. The power supply components and requirements are also much higher than LCD TVs;
Furthermore, most of the LCD monitors are not used in a single monitoring center. The ambient temperature is high and the ventilation equipment cannot be compared with the LCD TV home environment. This requires a higher reliability and stability of the LCD monitor.
Some people may say that this is only one of the words, as the industry's technical staff engaged in LCD products for many years, the author once encountered such customers. The customer did not understand the difference between the LCD monitor and the LCD TV, so he chose a relatively cheap LCD TV to fight the monitor wall. In the construction project, watermarks, unclear images, and cameras and matrix Mismatches and other issues were reluctantly solved through peripheral equipment. However, after one year of use, users began to continue to have a black screen phenomenon of LCD TVs. After returning to the factory for maintenance, all of them were burned out. The free maintenance of the manufacturers was over, and the users also had products. The stability was questioned and all replacements were required for professional LCD monitors. The loss can be imagined.
As a system integrator, when selecting an LCD monitor, it is far from enough to select a well-known brand or a big brand. The LCD monitor has its own particularity because its product has a short time and the market has not yet been used on a large scale. The manufacturers are not large in scale and each has its own brand. Beijing Xinkehua Technology Co., Ltd. began researching and developing its own “Xintu†LCD monitor in 2003. It is dedicated to the promotion of independent brands in LCD monitors and industrial The liquid crystal display industry is well-known, and all four products have their own patented technologies. They are constantly improving the design of their products and improving the quality of their products.
