Nanjing LCD stitching offer, Tianjin Cheap LCD splicing screen, LCD screen splicing Shanghai foreign suppliers 华凯瑞 drag 42-inch LCD screen splicing splicing controller and can be called a large-screen display, a video wall controller or TV wall splicer, its The main function is to complete the picture after a red signal into N blocks assigned to the N video flash unit (such as a rear projection unit), the end to form a large screen with multiple common video unit. It can support a variety of video equipment together access to reach the required function of mosaic wall. It is called outside the trailer, because these mosaic wall is divided into two separate some one some flash and some, such as rear projection TV which can consist of ordinary projection unit; the other is this some splicing control device, its function is to end the group consisting of a plurality of physical output resolution is superimposed flash output, so that the screen flashed a picture. Followed by the more prosperous large screen LCD splicing mall accompanying game will be more encouragement. In this mall continues to increase, the cake bigger and bigger went into this work the company is also increasing. During this period, not only the traditional stitching large screen companies, some of the traditional television flashed manufacturers are now entering into this work in order to be able to win a cake waiting. In order to increase the machine itself standby time and enhance the driving ability of the liquid crystal flash, LCD manufacturers have developed can be satisfied with the low voltage and low frequency conditions using a low threshold voltage of the liquid crystal. It has the following features: time low threshold voltage of liquid crystal monomer with polar groups in the monomer without polar groups presents homosexual representation isomer chromatography conditions under standing shorter. More monomer component with a polar group, also means more liquid water molecules as well as a brief liaison with other free ion polarity, then dropped LCD capacitive resistance, leakage current and power consumption and resulting increase great. When the molecular chain polar liquid crystal monomer after UV intensified polar molecular groups constituting briefly intertwined neutral molecules, to become a non-smectic fault condition, which constitutes the threshold voltage increases, the anchor of the guide layer given the role of insensitive, low-voltage drive lost talent. TN liquid crystal molecular chains are usually shorter than the characteristic parameter adjustment difficult, so the comparison is not the same characteristics significantly. STN STN LCD is revealed through the data model to calculate the length of the liquid crystal molecules, electrical and optical properties of the required parameters, and the chemical composition of a variety of molecular chain structure similar to a monomer having polar molecular groups are not the same, the mutual distribution into a feature similar series of LCD. Not the same series of the STN liquid crystal generally has a completely different molecular chains, therefore, not the same series of the STN liquid crystal unless the manufacturer instructions can be assigned to each other, but can not be assigned to each other. Life expectancy with respect to the use of DLP and PDP, a liquid crystal is very long, and the power is low, less heat, the failure rate is very low. PDP plasma prone plasma traces its dynamic life number may appear up to tens of thousands of hours, but in the static pictures exhibiting high luminance, it would perhaps five thousand hours after presentation screen burn; DLP lamp life and number of only three 1000-5000 hours on 24 hours of continuous use of security monitoring large-screen mosaic wall selection, the selection should be thinking crystal mosaic wall, in order to advance the use of power, decrease costs and protect the use of capital. DID show a new skill is skill, high brightness, high contrast, high color saturation, high color uniformity and longevity number, even a short time between failures and other characteristics, is currently in use on many occasions there has very good visual effect. Also has appeared clear, larger viewing area, appeared share adjustable, bright colors bright and very thin body, the use of long life expectancy. DID appear mostly former use as a standalone screen all the way, followed by the development and advancement of science and technology, to show the current DID narrow mosaic screen is now available for use (≤24mm), and you can get an excellent show effect. DID splicing due to the use of a thinner body, can be considered the use of space for the user to save more, stitching combinations simple easy to use DID mosaic wall can be said to be less apparent role in funding to get an excellent, cost-effective.
