In recent years , LCD liquid crystal mosaic momentum of rapid development , it is still not truly seamless splicing . Truly seamless splicing is the projector edge blending techniques . With the development of hardware and software technology , seamless splicing technology into a very mature stage, and has been widely used in command and control, virtual simulation and training , industrial manufacturing and design , scientific research and complex decision-making process , in the display of the exhibition , visual entertainment, advertising other fields are also increasingly common. Below the lower edge on the chat integration technology.
Seamless edge blending technology is a special, high demand projection display applications , 160x160 lcd can achieve multi-screen image together, and to minimize the gap splicing splicing technology that completely overlap . Seamless splicing technology requires not only a complete ultra- sharp screen for projected oversized projection screen is also used for special requirements .
Seamless splicing technology has undergone a total pure hardware fusion technology, pure software integration technology , hardware and software integration technology three stages:
Pure hardware fusion technology is to integrate optical shading images, pure software integration technology is done through the electronic circuit image fusion processing , hardware and software integration technology is the integration of both optical shading treatment , another electronic fusion .
Due to hardware integration can better handle the fused image of the black balance, and image processing software integration can be better white balance , a combination of both hardware and software integration technology will be able to achieve more perfect fusion of some real color image reproduction .
Speaking from a mosaic effect , seamless splicing technology has gone through three stages of development: hard edge stitching, stitching and soft edges overlap fusion splicing .
Hard edge stitching obvious dividing line ( ie physical patchwork ) , can not achieve the integration of panoramic display ; overlap splicing refers to the two projectors cast images in the mosaic punishable by a superimposed manner overlap, but there was clearly this splicing Flatten the brightness of the superposition of at bright areas appeared ills that affect the implementation of a seamless effect .
Soft edge fusion splicing process through the edge fusion technology , both to achieve the full integration of the two sides ,character oled
display but also eliminate the overlap splicing caused by overly bright areas, and soft edge fusion splicing can be adapted to planar, cylindrical , spherical and other curved shapes splicing , have much broader applicability. Soft edge fusion splicing technology is the current mainstream technology, but also the future direction of development.

Speed and quality of contradictions Character LCD Modules
For the current terms of LCD monitors, LCD viscosity, response time and quality has a very close relationship between.
Because, LCD sticky, the colors on bright, but the response time is slow; while the LCD thin, and fast response time, but the color fades. The high voltage can achieve higher response rate, no doubt. However, the characteristics of the liquid crystal molecules are obtained at different voltages in different colors, so that the voltage is the result not only raise the color is incorrect. Therefore, using the same materials of the same generation OLED Module, fast response for gamers, slow response times and better color performance 2D display sharper, more suitable for graphic design and office, Internet application.
Grayscale 4m s become mainstream
Most commercially available liquid crystal display nominal response time between black and white is the time required for conversion, of course, is the fastest LCD black and white conversion and not the slowest. LCD conversion between other colors, such as white to gray, red to blue, etc., than between black and white shift needed for a long time. A nominal 12m s LCD display, display the red dot blue dot to become time may be required for several tens of milliseconds or more. When playing games or watching movies, the screen content can not just do the darkest switching between white, but colorful colorful screen or different shades of gradations, these are doing grayscale conversion between.
As people requested more "harsh", 8m s, 5m s gray level response time of lcd moduleproducts in the market is just too short-lived, less gray 4m s products have become the dividing line between the mainstream market, adapt to this market demand , manufacturers introduced 4m s even lower gray response time of LCD products, they have gradually appeared on the market. Since 19 inches this grayscale LCD product prices are relatively high, so users are generally 17 inches or optional objects, in this small series at 4m s elected several gray response time of less than 17 inches LCD products, so that consumers who also feel this "speed experience."

Self-leveling epoxy coating introduction Character LCD Modules
Clean-resistant epoxy self-leveling epoxy floor coating is a coating film-forming material, and then by adding a curing agent, non-volatile reactive diluents, additives and pigments and fillers preparation of a solvent-free high performance coatings. Epoxy self-leveling coating film forming process is a chemical method, first the soluble low molecular weight epoxy resin is coated on the substrate surface, graphic lcd
modules leaving the reaction between molecules to further increase the molecular weight or the formation of crosslinking tough film. Where the optional requirement epoxy resin can be at room temperature deposition, and the coating film is required to have a viscosity relay, strong mechanical strength, chemical resistance and good electrical properties.
Comparison of domestic self-leveling coatings
Coating after the construction can achieve smooth feature called leveling, leveling coating applications is a very important issue, and it affects the apparent gloss coating, when the paint brush to the substrate, will leave brush marks, this brush marks may be due to the flow of paint dried before mitigated. When the coating is poor leveling, can be seen with the naked eye in the case uneven coating. When the difference to the naked eye can not see, at this time, said the film is flat, Graphic LCD Display smooth coating to the uneven gravity is not the driving force, but the surface tension, under normal circumstances, leveling can be used ORCHARD formula evaluation. Theoretically, the lower the viscosity paint or coating the thicker the better leveling. Because self-leveling coatings particularity, the general requirements of the film after the film has good leveling, while simultaneously maintaining good surface properties. Throughout the current domestic and self-leveling epoxy material system, there are two main technical guiding ideology, one of many domestic manufacturers generally use the guiding ideology (A class), A class technology theme is: the use of an appropriate amount of solvent to achieve Good leveling coating, the coating process, the coating of filler will gradually decline, the cured film has good leveling, but the surface hardness, wear resistance is poor, while in the construction may be will produce more spots such as lack of surface flaw, which is one-sided pursuit of leveling results; Second, foreign technology and many other manufacturers follow (B class), while class B self-leveling resin coating is to ensure good leveling while still maintaining the uniformity of the filler, the cured coating film so as to ensure better apparent decorative.
