STV will become the mainstream of outdoor large LED display billboard technology

In recent years, many large entertainment video (Vision), and the arena will be used as lighting and display using respectively in concert, this large video in the exhibition hall, through the computer image (Computer Graphic) in addition to the display of corporate image, but also a detailed description of goods, at the same time as the venue layout art. As mentioned above, the electronic display advertising industry (electronic display billboard) after 40 years of exploration, finally combined with the art and performance gain. The electronic display billboard is involved in many fields of technology, advertising and entertainment company in almost every day with all kinds of electronic products, from a neon lamp, lamp extinguish billboards, until the motor components of the movable doll, characters, are included in the electronic display advertising category in recent years, the electronic display billboard even with the illumuination overlap. With flexible and high requirement of recreational function of making electronic display billboard must use the bulb on / off control and dimming control, electronic display billboard structure and Pachinko brother are very similar, for example, a collection of 256 light bulbs as a point out of control, you can display a variety of patterns and simple character (character), if the structure of Pachinko brother expansion placed in the photoelectric display board, then use RGB bulbs to replace monochromatic light bulbs, can serve as color image display. Although the control on the same lamp extinguish, and dimming control amplification version, but the show and the art layout based on the demand, mostly bulb lattice arrangement, mini bulb is screen shape, net curtain arrangement, then using this kind of fiber performance fireworks screen, electronic billboards display application requirements lightweight, can be flex, easy setting and highly entertaining picture. Display the number of electronic billboards use light bulbs is reduced continuously, various types of LED substitution, forming the so-called "LED" if the increase in the marquee, the number of control points becomes large "LED display". Caption: in addition to display the image of the enterprise through the computer image, but also to detail the goods, but also become a venue for the art. (Shenzhen Dicolor OptoELectronics) with a light weight and control unit complete separation characteristics of the Japanese industry for 99 years to develop LED and can display computer graphics, image Vision (STV: See Through). STV is a single module on the wire, RGB LED group with a certain arrangement spacing (cluster) formed a billboard electronic (Electric Ornament Bar), the lighting controller output DMX 512 signal, directly control the electronic billboard single, because electronic billboard is at intervals, so as to form an image picture display image data PC. The design of convenient construction based on electronic billboard a mesh fixed on the substrate if the substrate can reach the soft degree, in addition to form a similar mobile cable (Cab tire) outside the flexible characteristics, can also see from the front (60% penetration) net curtain, see behind the second screen image at this time, re integration of lighting effects, show back objects, or from the back projection lighting, you can get the traditional LED display can not reach the stage effect. STV system as a whole is very light, display unit, power supply, control unit is completely separated, in the past difficult construction site can easily set up. STV was originally set to distance 100mm LED electronic billboards, if encountered when the venue is not wide spacing will be very obvious, in addition 5.4m x 7.2m (360 inches) in size, can only display PC 72 * 54 pixels (pixel), can not fully reproduce the original image, countermeasures for improving the screen size and resolution. In the past most of the use of 16.2M x 57.6m display, the use of 100mm module in the grid spacing, set on a LED electronic billboards every 50mm, double screen structure forming simulation 70mm spacing, the researchers then developed the so-called "image mesh (Image Mesh), high resolution images. The image screen system is divided into a display unit, a power supply unit, a signal conversion unit, an output unit (an image signal input unit), and a signal transmission unit group. Caption: after 40 years of exploration, the billboard finally realized combined with art and performances of free electronic display. (www.Barco.com) system for longitudinal dimensions (216 pixels) 5.4m x 7.2m (288 pixels), due to the development of great importance to permeability (ST: See Through), so the researchers dug hole in the mesh substrate component is arranged in the substrate 5mm wide use of automatic assembly equipment, the structure requires the connector frame the structure and fine equivalent strength, therefore the design phase of the substrate design, component encapsulation, frame structure review improvement work. The system uses the DVI video interface mainstream display unit 1 full-color 3 surface package type light emitting diode, a longitudinal 12 x 12 settings, 300mm Affirmative module, signal by DMX512 converter and lighting control coordination. The main feature of the visual system is light and thin, although the back side of the substrate is not as flexible as the STV can be bent, but through the appropriate component settings, it can be bent radius 500mm. The 9 module is fixed on the frame to form a 900mm square unit, and can be combined to form a longitudinal 5.4m * transverse 7.2m specification display. Pictures of the 6 power supply unit can drive the 900mm Affirmative unit; the main function of signal conversion unit for the input image signal, encoding the light signal is transmitted to the DMX512 coordinate converter decode; display module using DMX512 drive signal conversion unit, in order to reduce the number of wires, until all the way near the optical fiber transmission module. The image signal input unit is a digital video interface (DVI: Digital Video Interface signal)
