With its inherent advantages: ultra-thin thickness, no radiation, and no flicker, LCD has quickly become a hot spot in the display market, occupying a considerable market share in the large-screen market. By introducing the technical features of LCD splicing large screens themselves and analyzing the recent breakthroughs in the technology and cost of LCD splicing screens, it is hoped that the majority of users will have a certain understanding of LCD splicing large-screen display walls. When the large-screen display wall is close to the needs and reduce costs.
The imaging mode of the LCD liquid crystal splicing screen in the LCD liquid crystal screen determines that it has: completely right angle, there is no so-called geometric distortion phenomenon in the CRT display, does not require a complex electron gun structure in the CRT display, the volume can be done very small, electricity Very low consumption, zero radiation and no flicker. These advantages make the LCD splicing screen popular in the fastest time, and these advantages are all users in all professional fields hope to use, but in some technical indicators, LCD LCD splicing screen is inferior to CRT monitors. For example, response time, rich colors, these shortcomings make professional users difficult to choose between LCD LCD splicing screen and CRT display. Below, we may compare the LCD splicing screen with the CRT display on several major display performance indicators to see what differences make the professional users hesitate to choose the LCD display.
Response time
For this indicator, it can be understood as the reaction speed to the input image signal. It is the sum of the time from black to white and from white to black above the same point on the panel. If the index is too long, “smear†will occur when the image is switched or the video is played quickly, which affects the use. For CRT monitors, the response time is generally around 1ms, and for the current representative Levinview NICEVIEW LCD LCD splicing screen, the early LCD is about 80ms, and the long response time is the most troublesome problem in LCD use. However, this problem has been basically solved, and now the latest LeTV NICEVIEW LCD LCD splicing screen has a response speed of about 25ms. Although there is a certain gap compared to the CRT, when watching a DVD, it needs to display 33 frames per second. The response time is less than 30ms (30ms = 1000/33). For playing action games, if the QUAKEIII is very demanding, if there is no “smear†at all, the screen display speed should be more than 60 frames per second, that is, the response time is less than 16.6ms (16.6ms=1000) /60). Currently, LG, BenQ and Samsung have introduced LCD display products with a response time of 16ms on the market. However, for most users who mainly use Internet, office, data processing, and enjoying image data, the 25ms response time LCD The product is fully capable of meeting the needs. Therefore, at present, LeTV NICEVIEW LCD splicing screen manufacturers provide LCD products with 16ms response time and LCD products with 25ms response time.
Number of colors
The number of colors refers to the number of colors the display can display. The higher the index, the richer the picture. In addition to the response time, another important factor affecting the purchase of LCD monitors by professional users may be the number of colors. Now, CRT monitors can basically display 32-bit colors, ie, 232 colors, 4294967296. In the early days, LCD can only achieve 16-bit color, about 65,000 kinds. In the recent period, with the advancement of technology, LCD can display about 24 colors, about 16 million kinds of colors. If you simply look at the indicators, LCD is still a bit far from the CRT, but in fact, 16 million colors can also meet the needs of most applications.
LG's ColoriFic technology is unique in enhancing the technology of color performance. ColoriFic adjusts the interval between the applied voltages to make the color change more consistent, and separates the signals to make the signal enter the liquid crystal. After the display, the horizontal signal and the vertical signal are clearly separated during the continuous transmission, forming a dual signal track.
The separated signals are more precisely transmitted to the liquid crystal panel, so that the color purity and sharpness are effectively improved. In addition, ColoriFic has a variety of color, brightness, contrast, and sharpness combinations of display modes such as Office, Internet, movies, etc., for users to choose, and also supports a variety of printing devices WYSIWYG True color output.
Viewing angle
The LCD splicing screen has a disadvantage compared with the large screen of the CRT, that is, if the user tilts a certain angle, the screen image cannot be seen clearly. For users who have used laptops in the early days, they must have some experience. When using a laptop, the screen image is the clearest. If the viewing angle is tilted to a certain angle, the screen image will not be seen clearly. The maximum angle to see the screen image, this angle is the viewing angle. The viewing angle can be further divided into a horizontal viewing angle and a vertical viewing angle. For this shortcoming, developers of LCD splicing screens have also made great efforts. The viewing angle of LCDs can now reach 178 degrees. Actually, no one actually looks at the screen with such a tilted angle. For professional users, they are always facing the screen.
For the indicators of resolution, brightness, and contrast, LCD splicing screens and CRT monitors are basically the same. If the LCD splicing screen is completely acceptable in terms of technical indicators, the only thing that needs to be considered is the price. LCD wall is a new display carrier that has gradually entered people's life and work in recent years. Because of its fashionable, low radiation, energy saving, space saving, small splice gap, and stable and clear picture, it is loved by the majority of users. With the start of the market, the price drops, so that more users have the opportunity to use this product. Therefore, a display wall composed of LCD liquid crystal splicing screen units has been promoted and applied by various industries. It has become an indispensable display device for large-scale exhibitions, public places, video conferences, multi-purpose halls, television stations, entertainment, television monitoring and other places.
to sum up:
In addition to the above indicators, the choice of LCD LCD display wall must be carefully selected, calm thinking, first select the brand of high-profile products. The outstanding brand is the background of the large-scale LCD panel plant. As the most important part of the LCD components, the LCD panel has always been the key to determining the quality and price of the LCD splicing screen. It is backed by advanced and reliable panel production lines. The quality and comprehensive services can naturally be guaranteed.

F Ground Screw is called by our staff and it means Ground Screw Pile with flange. Ground Screw with flange is more important type of ground screw to build or fix buildings and it is usually used in construction as the flange of ground screw piles is flat and stable when ground screw and other buildings have a connection. The flange have different shapes as the customer`s needs. Generally, we have enough stock in round shape flange of ground screw and hexagon shape flange of ground screw because of having plenty of customers need to purchase these both types to support solar panel structures to constitute one set Solar Ground Mounting System.
