P10LED traffic monitor

P10LED traffic display 1 3 9 9 2 8 8 9 9 6 3 LED Display Screen system equipment components Description 1, the control panel? The control system uses ultra-large-scale programmable gate array device, greatly simplifying the control circuit design, strong performance High stability. ? Using the hardware control linear calibration technology, LED dot matrix constant current drive mode, the display color uniformity, high definition. ? The gray level is 256, the three primary colors can display 16.7M kinds color. ? Digital signal differential transmission mode, so that long-distance control display, signal distortion, no delay. ? Display by computer control, real-time display synchronized with CRT-by-point scanning. ? Screen system board using surface mount (SMT) devices. ? Multimedia video systems with powerful editing, playback, support for multi-screen, multi-zone variety of display, can arrange a variety of video, digital, text, images, 3D animation and other information, can receive, broadcast TV, VCD , DVD, LD and other video signals. ? Communication line 8-core shielded network dedicated high-frequency signal transmission line, the control system is configured multimedia video-specific software. ? Display stand according to customer requirements and design by a professional infrastructure companies, for the system. 2, switching power supply switching power supply noise-free ultra-thin shape, reliable performance. 3, the cell plate briefly? LED display screen by a rigid connection between the cell plate assembled from Cascade, cell plate and cell plate, flat is good, and easy installation and removal, screen surface smooth, uniform display tube , the display clear, high contrast. ? Unit board at the factory, you can pre-correction brightness deviation of all points, the system can be adjusted. ? Should display with wall mounting, reliable solid foundation, the installation of 15 degrees forward, to ensure a positive display viewing angle and effect. 4, the pixels package modular design, compact structure, installation and maintenance; pixels packaging technology: high-temperature aging plastic for housing, epoxy resin and PC using imported materials, with high-pressure nitrogen packaging, high-temperature plastic to ensure durability and aging no deformation, can guarantee to reduce surface reflection interference generated color disorder, put a good package after sealing the room to dry naturally to ensure that no deformation and reduce adsorption phenomena. Display cabinet structure design, and the junction of the pixels within the rail using the pad apron heat seal tightening mode; I developed specifically for outdoor screen convection cooling solution. Special duct design, completely solve the technical indicators change outdoor screen due to high temperatures affect the semiconductor element and optoelectronic devices. The purpose is not only ventilation, but also anti rain drift into. All hardware, no software drivers, high-speed, reliable, direct, multi-layer software to avoid loading; display high brightness, are stable, clear, flicker-free; all available on the computer monitor can display graphics on the display displayed, the software compatibility; use of non-linear color correction technology, excellent display, high resolution, clear graphics, smooth animation, no mosaic; a light emitting diode is elliptical structure, viewing angle, light effects good, high luminous efficiency. 5, the anti-gradation correction LED is lit duty cycle control, its brightness a linear relationship with the driving signal. The current video signals are pre-corrected, if directly for television broadcast video signal sent to the LED display, LED display gray will cause distortion, so my company LED large screen display system was inverse correction to eliminate distortion. 6, noise reduction noise caused by the transmission medium, and quantization noise analog signal and digital signal conversion, greatly affect the display of the video display, it must take certain measures for noise reduction. I use a large-scale programmable integrated circuit developed LED control systems and median filter recursive functions, to better improve the viewing screen, full-color video image. 7, deblocking phenomenon ? For all LED light tube brightness binning, the entire screen with the same file tube. ? All components undergo a rigorous screening, to ensure consistency in device parameters. ? Module flatness and precision strictly controlled to ensure precise positioning of pixels package. 8, the advantages of LED display currently popular on the market a large display device with a magnetic flip screen, TV wall (CRT display), a projector, a fluorescent tube display, a light emitting diode (LED) display, plasma (PDP) display screens. LED display compared to other display technologies can not be replaced has some advantages: * Long life: LED life of more than 100,000 hours; * Fast response: This is a common feature of the semiconductor device; * Visualization distance: LED single point diameter up to 52mm, visual distance of 500 meters or more; * specifications varieties: LED display indoor and outdoor, monochrome and color, colored; * High degree of digitization: all-digital, high-resolution graphics mode can be achieved; High Brightness: can be used outdoors, such as traffic lights, anti-fog, etc; · viewing angle: indoor display up to 160 degrees. 9, the control room control room requirements: the control room area of ??not less than L * M = 3m * 3m · interior decoration, ceiling, flooring · indoor distribution cabinets, head of the control of various devices, leakage protection · grounding protection network , grounding resistance <3 ohms
