Liquid crystal splicing seamless display deviceTechnical Field
The invention belongs to a liquid crystal splicing seamless display device.
Background
The super-large screens at home and abroad are formed by independently and physically splicing LCD display units. Because each display unit is physically independent and has independent packaging, when two or more display units are spliced into a large screen for display, a larger gap is formed at the splicing position of the screen, and the visual effect of the picture is influenced
On large department stores or high-rise buildings, large outdoor large screens are often seen, through which the merchant or business can display some promotion information or advertisement thereon, giving visual impact to consumers. And because the narrow-edge splicing always has splicing gaps, the original image is segmented. The product uses the corresponding optical material hypotenuse on the super narrow limit concatenation screen of a liquid crystal, and hypotenuse produces seamless concatenation effect all around. The original product has black edges, and a line is arranged in the middle of a spliced picture, so that the product is not beautiful.
