The ball screen projection is an emerging display technology that breaks the limitation that the projected image can only be a flat rule graphic.
The spherical projection is like a magical ball in the hands of a wizard, dynamic and dreamy. The multi-channel edge fusion software is used to realize the splicing and correction of large-size images on the curved surface, eliminating the deformation of the projected image on the curved surface, and forming a panoramic image of a special curved surface or even a spherical surface, bringing an unprecedented dream experience.
The ball screen projection system realizes the panoramic image of special curved surface and even spherical surface by using the seamless splicing technology of large-sized image content on the curved surface, giving the user an advanced scientific and technological experience. The user can perceive the content of the sphere projection in 360 degrees, increasing the amount of information the user obtains information, and providing an excellent performance platform for some things that can be better represented on the sphere.
The spherical projection is divided into two types according to the position of the projector. One is the inner pitching ball. The projector used is located inside the sphere to project the image into the sphere. The other is the outer pitching ball. The projector used is located outside the sphere. , projecting an image onto the outer surface of the ball.
Pitching
The projector is placed at the bottom of the ball screen, with a fisheye lens, the signal is reflected and projected onto the spherical screen display. The internal ball throwing device, with its special function resin earth screen and high lumen projector, can form a seamless display on the surface of the ball screen, and supports multi-window and multi-screen display, which can be very stable and vivid. The well-designed texts, patterns, animations, and videos are clearly projected and displayed, creating a super-shocking dynamic visual effect, and supporting new products with multi-window and multi-screen display effects. It projects the text, graphics, animations, and videos of the design very clearly from the inside of the ball. It is amazing. The digital ball can play animated graphic text and even video images. The projected image can be displayed in the ball very stably and vividly. It is very clear. The hemisphere and super hemisphere with a diameter of 1~2 meters can be designed and developed according to the special needs of users. Curtain projection digital ball; screen angle of view from 150 degrees to 240 degrees, all optical indicators are suitable for digital image projection standards, clear picture, good color reproduction, high brightness and contrast. Can be widely used in museums, entertainment, astronomy teaching, science, advertising, exhibitions and other industries.

Pitching
It is through four projectors to project the ball screen from the outside in four directions, and the edge blending technology presents a spherical seamless realistic picture, and can ensure that the picture is not deformed, the picture quality is clear, and the color is gorgeous. Hanging the throwing ball in the hall creates a stunning visual effect. And according to the actual needs of users, a human-computer interactive application system can be added to allow content to interact with participants and viewers. Through the edge fusion technology to create a spherical seamless realistic picture, the picture can be made without distortion, the picture quality is clear, and the color is gorgeous. Hanging the throwing ball in the hall creates a super-smooth visual effect.

The external dome system requires multiple projectors, spherical screens, and large site requirements.
The inner projection screen projection system only needs one projector, the inner projection ball screen, and the site requirements are small.

The internal pitching technique uses virtual reality technology to create a 360-degree dome virtual scene. Since the content of the dome projection is to be fully displayed for a large viewing angle (more than 180 degrees). Therefore, the fisheye projection used in the ball screen system can produce a stereo immersion effect on the spherical surface, especially the virtual sphere. In computer graphics, fisheye projection usually has two cases, an orthogonal fisheye image and an isometric fisheye image, the former will cause stretching at the zenith and compression at the equator, while the latter can achieve pixel in The average distribution on the sphere.

Storm Circuit has been producing Multilayer PCBs for over 10years. Over the years, we have seen all types of multilayer constructions from various industries, answered all types of multilayer questions, and solved all types of problems with multilayer PCBs.
Multilayer PCB is a circuit board with two or more layers. The material unlike Double-Sided PCBs with only two conductive layers all multilayer PCBs is that it must have at least three layers of conductive material, and the PCB boards are buried in the center of the material.
Benefits of Multilayer PCBs (compared to single or double-sided PCBs)
Higher assembly density
Smaller size (considerable savings on space)
Increased flexibility
Easier incorporation controlled impedance features.
EMI shielding through careful placement of power and ground layers.
Reduces the need for interconnection wiring harnesses (reduces overall weight
