    LCD splicing screen is not exist independently, the use of liquid crystal splicing screen all need through its various parts and components, LCD splicing screen as the display device, the principle and general displays very much the same. LCD splicing screen in use typically use spell near controller, embedded stitching controller generally only technicians are often contact, but can also be too much for the users know the LCD splicing the structure of the screen.     LCD splicing system consists of liquid crystal splicing display unit, LCD splicing bracket, LCD splicing of controller and the signal source, and liquid crystal splicing controller is divided into inner and outer controller, and built-in is called built-in embedded LCD splicing, embedded splicing is also called "Mosaic" "LCD splicing unit" "big screen splicing unit" "built-in joining together" "stitching processor", "back small bags" is specially used for liquid crystal panel, integrated with LCD drive, power supply, image display and serial port control; All signals through hardware processing, more stable and reliable, the startup time is shorter, prevent virus interference, affordable.     Embedded principle of joining together the original picture of the entire a transmitted signal arithmetic processor, arithmetic processor in the form of ID address encoder began locking their place in the female images, in binary BCD order (BCD horizontal coordinates: from left to right, vertical coordinates and BCD: from top to bottom) began operation cut into more child, the processor will each operation good data directly to the LCD driver board, driver board will color, brightness, contrast after the calibration parameters, such as in an LVDS transmission to LCDIC imager to form images. Because the embedded splicing device USES the hardware architecture of digital image processing technology each time only one type of signal processing, so don't need a more powerful CPU core to operation channel signal. Simple single image splicing function for some customers only need large screen display provides a very flexible and convenient, to the current configuration has irreplaceable position when the LCD splicing screen but this spell type splicing device within just internal display pixel processing unit, the result is a synthetic images, high resolution cannot solve the signal splicing and signal processing, more than any size at any position window is more applications in a single signal of promotional display and according to the unit or adjacent units splicing more simple image processing applications.     Embedded stitching controller does not generally used alone, it mainly is to configure the display equipment work together, an embedded LCD splicing screen splicing device is the most suitable parts. In the actual application can also be replaced by the peripheral image processor. Been widely used by embedded splice LCD splicing screen, LCD splicing controller pictures big, strong visual impact, has the very good display, demonstration, advertising, publicity effect. So, whether the LCD splicing screen which component, is playing an important role, to make the LCD splicing screen effect more perfect. DDW specializing in the production of liquid crystal splicing screen, the LCD splicing screen the most professional supplier in China, as a professional supplier shall have the duty to let customers better understand the working principle of liquid crystal splicing parts professional technical guidance, the customer must be satisfied. And as a user, can also be appropriate to understand its principle, in order to better prepare pick stitching screen.

     LCD splicing screen back light source directly affects the brightness of the LCD splicing screen, the current high brightness LCD splicing screen has been widely used. Common liquid crystal splicing screen back light is divided into two kinds: one kind is backlight CCFL tubes, another is the LED backlight.      In general, a backlit LCD screen brightness CCFL tubes in 100 ~ 200 CD/m2, the brightness of the two CCFL tube backlit LCD screen in 200 ~ 300 CD/m2, with an increase in the number of the tubes, brightness can be increased. But by increasing the number of tubes to increase the LCD panel brightness at the same time, also increases the power consumption of the LCD screen. All aspects of the ascension, which would help the working life of the LCD splicing screen longer.    LED backlight refers to using LED (light emitting diode) for LCD back light. And traditional CCFL (cold cathode tube) back light, LED with low power consumption and low calorific value, high brightness, long life and other characteristics. And ordinary LED backlit LCD screen brightness can reach more than 300 CD/m2, increase power LED lights, brightness can meet the requirements of the sun visible brightness - more than 500 CD/m2 brightness, this can be in the sun visible LCD screen commonly known as super Bright LCD screen (Ultra Bright LCD Panel). At present, the LCD splicing screen mostly adopted LED back light, brightness can reach 700 CD/m2.     Ordinary CCFL tube backlit LCD screen in more than 20 ~ 30 w power consumption, increase the number of tubes, increased brightness, power consumption is also multiplied. And the LED backlit LCD power consumption are only a few watts, improve power leds, increase brightness, power consumption increase is not big.     Using LED backlighting can make the color more bright-coloured, ultra-thin appearance, energy conservation and environmental protection to reduce power consumption, long service life, high display contrast more clear. Liquid crystal splicing screen using the LED back light makes the picture clearer, higher contrast, life and growth, good color saturation, makes the LCD splicing screen won the love of consumers in the market.    

    DDW relying on the advantages for the application of liquid crystal splicing now has got the immortal achievements both at home and abroad, life up to 5-80000 hours, and liquid crystal splicing the overall system stability, maintenance costs are relatively cheap, become the best cost-effective large screen display system. The DDW to say about what are the four advantages of LCD splicing!       The LCD splicing     1, LCD splicing not because the signal is caused by frequent switching effect is not ideal, this user completely don't have to worry about! And the cost and stability can be very good application. Small size high resolution is the main distinguishing feature of the LCD splicing, and size can according to user requirements and actual reasonable install LCD joining together to show, not only saved the cost to the customer is more convenient in installation.       2, LCD splicing of high stability, long life, low maintenance cost, therefore all-weather work no problem, even if the actual need to run for a long time. Emperor of emperor ai can meet user requirements, actual 7 x24 (hours) to run, to be able to ensure stable and reliable operation of the whole system.       3, relatively speaking, the combination of the LCD splicing space more broad, and both can use small screen splicing also can use screen splicing, also can carry on the effective mixed assembling size screen, can quickly amplified to judge on the whole system environment, choose the right way of joining together of long-term effective planning, to meet the requirements of the overall system.       4, liquid crystal splicing versatility, not only can achieve the whole screen large screen display effect also can realize multiple small screen display effect.       SHENZHEN DDW TECHNOLOGY CO., LTD was founded in 2009, is specialized is engaged in the LCD splicing supplier of commercial display solutions. Over the years, has been adhering to the "professional, reliable, user first" concept, will be professional, reliable products and optimal solutions to various industry. Company always walk in the forefront of the industry, to grasp the latest market trends, and constantly introduce the latest and the most optimal LCD splicing screen.
