Seamless edge blending techniques Character LCD Modules

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.
