LED display is in a stage of rapid development and growth rising. Now the LED display market presents great changes ,In addition to the traditional information display, the shape is also further ascension,Make it a better environment ,thus resulting LED irregular screen.
The LED irregular screen require higher research and development ability and production technology
Compared with the conventional LED display,LED irregular display screen pay more attention to the structure. Now LED irregular screen module mainly include fan, arc, circle and cylindrical, triangle, and other forms of structure. LED irregular screen prefer for users with special needs,Is mainly used in performing arts venues, outdoor media, the pavilion plaza environment.Due to the LED irregular screen appearance different, So for the manufacturers technical requirements are also more stringent,Technology does not pass ,will lead to many problems,Thus influence viewing effect, destroy the aesthetic feeling of the overall design,But more importantly, LED irregular screen of the circuit and the design of the structure is complex, so demand the manufacturer's high research and development ability.
The appearance of irregular module makes LED screen had better modelling ability
Before long a period of time,LED irregular screen are traditional rectangular plane module assembling or package.One of the most common LED irregular screen is big arc screen and plane circular screen.If display radian is small or other more complex cases, is not very good solve flat-fell seam and smoothness, so brings the problems such as display shows inconsistencies, mosaics, or the overall effect is not good.According to this problem, a factory research and develop the triangle, trapezoid shaped module.Can piece to synthetic spherical, diamond, precious stones, star and other regular or irregular geometry LED display.
LED display screen classification
LED irregular screen is a special shape on the basis of the LED display ,Unlike regular LED display shape,It can be arc and curved surface, square hexahedron, letters, and other irregular shapes.For different shapes, LED irregular screen were divided into the following categories:
(1) the circular arc form display Screen display surface as part of the cylindrical surface, its a rectangle
(2) Irregular shape display Screen display surface is an irregular plane, such as circle, triangle or irregular plane completely.
(3) the surface display Display shows the surface for a three-dimensional curved surface, such as spherical screen, screen polyhedron and awning.
(4) The mesh screen Display screen display surface is made up of a number of root model, and the screen point spacing is bigger, appear a higher rate, low contrast.
LED The spherical screen Spherical LED screen 360 ° full visual Angle, all-round play video, any Angle can feel good visual effect, no graphic problem. mapped earth, footbal directly to the screen, will feel true to life,.This type are widely used in museum, science museum, the exhibition hall.
The spherical screen currently on the market has the following three:
1.watermeion peel spherical screen:First appeared on the market of ball screen, commonly known as watermelon ball screen, it is composed of watermelon skin of PCB, it has the advantage of convenient, the disadvantage is that the diode (or north latitude 45 ° north of the equator south of 45 °) can't play the image, so the picture utilization is too low.
2.triangle spherical screen:Plane triangle of PCB ball screen, commonly known as football screen, it overcomes the watermelon ball screen poles can't play the disadvantage of image, image utilization rate is greatly increased. Defect is PCB sort is more, the pixels of honeycomb shape is arranged limit point spacing not less than 8.5 mm, so software also write more trouble, also entered the technical threshold is too high.
3.Six sides panoramic ball screens:Was only recently in the quadrangle of PCB ball screen, called the six sides ball screens. It's more football also the kinds of PCB panel. Closer to the surface with a relatively low barriers to entry, putting LED display, the minimum point spacing and plane LED display are similar, limit little or almost no limit, so the effect is much better.The ball on the physical size screen is composed of 24 classes with the same size spherical. It can be put into air box, tear open outfit is very convenient, easy to use leasing business. On the play, it will be a ball screen is divided into 6 images of the same, namely, up, down, left, right, front and back. Of course can also through software, alone or combined to play different video source. So it play effect is far better than watermelon ball screen screen with football.
LED panels with different specifications of the special LED module assembled, without being limited by the screen size,Can be flexibly assembled into any customer need text, graphics and LOGO etc.Application in the building roof, well-known enterprises, Banks, securities, municipal construction, landmarks, etc., can promote the commercial value of the enterprise.
