With the advancement of technology, the huge CRT will come out of the market sooner or later, and it will be replaced by liquid crystal LCD products. Although the pace of the monitor field is slower, the emergence of liquid crystal LCD monitors also confirms the trend of the times. A great qualitative leap has occurred in every process of the development of the monitor. From black and white to color, the monotonous world of monitoring images is moving towards a world of colorful, colorful and vivid images; from blinking to non-flickering, bringing health to the monitoring staff; then from CRT to LCD brings environmental protection, believe This is the ultimate development goal of the monitor. In the monitor market industry, due to the price and performance limitations of early LCD monitors, CRT monitors once occupied most of the market space. But in recent years, with the rapid development of the market and technology, LCD monitors are rapidly seizing various emerging monitoring applications. Due to the rapid development of LCD monitor applications and the shrinking market of CRT monitors, CRT monitors are facing the fate of front-end picture tube manufacturers, chip manufacturers, and complete machine manufacturers. It is expected that the market will be very popular in the next two years or so It is difficult to find traces of CRT monitors. At the same time, the future of LCD monitors will also face more challenges. I believe that LCD monitors will continue to develop in the direction of high definition, high brightness, high contrast, low power consumption, long life, ultra-narrow edge, and low price. LCD monitors and LCD TVs have a lot of interoperability in display principles, so the technologies in their respective fields are affecting each other's development. This article will proceed from the upgrade and improvement of LCD monitor technology, focusing on the application problems of LCD monitors: 120Hz frequency doubling technology The so-called 120Hz technology is actually a technology for frequency doubling and interpolation of TV image signals, that is, changing the original 50-60Hz field frequency to 120Hz. As we all know, after increasing the refresh rate of LCD TVs, the smearing phenomenon has been improved to a certain extent, and the high refresh rate can also make the dynamic picture clearer. Because LCD monitors and LCD TVs have the same imaging principle, in order to overcome the inherent smearing phenomenon of LCDs, major monitor LCD screen manufacturers have launched 120Hz field frequency displays, but the core processor of the monitor was only 60Hz at the beginning. For the field frequency, in order to achieve compatibility with the 120Hz screen, the frequency is doubled between the processor and the screen, and the field frequency is changed from 60Hz to 120Hz. The new LCD monitor's processor chip has already realized the field frequency multiplication function. Through the frame insertion method, on the premise of ensuring the image effect, the response time of the image is shortened better than the 60Hz solution, and the tailing is reduced. phenomenon. Full HD technology With the advancement of LCD technology, full HD 1920x1080 resolution TVs are gradually popularized. In the surveillance field, the two megapixel front-end cameras output full HD 1080P signals. However, in common LCD monitors, only 1366x768 HD resolution, It is impossible to achieve a true full HD experience, so the current LCD monitor technology also uses a full HD panel with an HDMI interface, which can fully realize the point-to-point display of full HD signals. Front-end output devices such as cameras and DVRs with 1080P signal output must be connected to monitors with HDMI interfaces, on the one hand to achieve high-definition reproduction of the picture, on the other hand, because the video and audio are on a cable Medium transmission makes the construction of the monitoring system relatively simple. DID technology DID technology is the first DID (Digital Information Display) technology introduced by Samsung in 2006. It has now become an industrial standard design, LCD screen that can work continuously and stably for a long time (24 hours a day, 365 days a year), can adapt to harsh work Dedicated LCD screen for the environment. As its unique display technology, it is different from ordinary liquid crystal displays in that it improves the arrangement structure of liquid crystal molecules, and can be placed in horizontal, vertical, and suspended ceilings. It has the advantages of high brightness, high definition (1080P), long service life, stable operation and low maintenance cost, and its color saturation is high (DID can reach 93%, while ordinary LCD screen is only 72%, reaching Higher contrast and brightness, and a long service life of 80,000 hours. The most successful aspect of DID technology is that the frame is getting smaller and smaller, which is completely suitable for LCD monitors used in splicing walls. As far as optical splicing is concerned, it has ranged from 23mm on the narrow side to 7.3mm on the ultra-narrow side. The reduction of the LCD greatly improves the visibility of the LCD wall, and has become closer to the width of the PDP and DLP. With the improvement of technology, the minimum splicing seam has been reduced again to 6.7mm, the optical seam of the LCD monitor has reached a minimum of 7.3mm, and the horizontal and vertical viewing angles have reached a maximum of 178 degrees. USB interface Due to the particularity and complexity of the use of monitors, most are mostly all-metal appearances, and some special effects and requirements cannot be adjusted by themselves. Previous monitor upgrades required the use of special upgrade equipment and complicated upgrade processes. Today ’s LCDs In order to solve this problem, the monitor is equipped with a USB upgrade function, just like the USB function of an LCD TV, except that the USB function of the monitor is not for entertainment, but to upgrade the device. The manufacturer only needs to provide the user with a program that is prepared according to the user's needs. After the user copies the program to the USB flash drive and simply operates the remote control, it can be quickly upgraded within half a minute, which is very convenient. LED backlight technology Because the monitor needs 7 & TImes; 24 hours of uninterrupted work, the life and power consumption of the monitor are the issues that users are more concerned about. At present, CCFL backlight technology is widely used in LCD monitors on the market, with a lifespan of about 50,000 hours. The backlight power consumption accounts for more than 70% of the total power consumption. With the introduction of TV LED backlight technology, we see that it is not only superior to CCFL backlights in terms of wide color gamut, ultra-thin, and high contrast, but also far superior to CCFL backlights in terms of power consumption. Following the boom of LED backlight applications in the LCD TV market, LED backlight applications have also quietly entered LCD monitors. Industry players hope to bring new business opportunities to LCD monitor products through the listing of LED monitors. However, the current price of LED LCD screen is more than half of the price of CCFL LCD screen, but if viewed from the perspective of long-term use, the cost savings of the monitor using LED backlight in terms of power is also considerable.
