Display technology advantages

para resolver punto de recompresa:0 - se queda para el fin del problema

(1) imported LED die production of high-quality full-color display: a perspective of large, power consumption, uniform color, thickness of thin screen, the screen body, light weight, low failure rate, easy maintenance advantage. (2) using PCTV Card: This card is a set of performance shows that capture, video capture features such as multimedia video card, the card comes with a Studio editing software. Studio Pinnacle Systems Corporation is a highly acclaimed software with the existing General common multimedia card comparison it has the following advantages: ① enables the user to their PC, making digital movies, capture video, edit and add style of the titles, transitions, and even his own music and digital video production narrative. ② Studio can let users choose to MPEG or AVI file format to output video and CD disk storage, or display the Web site, or create video email. Because Pinnacle Systems Studio can capture the company's range of devices to work, video capture never seen before becomes easy. ③ Studio applications are from like a VCR is easy to use with good, better, best quality form, and calculate how much the computer can store the video. Studio automatically discover and record the scene changes, so that editing ④ become easy to use Studio to create a fast and interactive process. using real-time preview window at any time in the editing preview of the film, that is the view that income. ⑤ If you do not like the title or effect, you can make a change and you can immediately see this change, video editing has never been so fast and fun. enough freedom, enough individual, but also with background music, voiceover and other effects. (3) using the latest DVI interface technology: DVI Interface (Digital Visual Interface ) is a PC, and digital flat panel displays (including) the industry standard interfaces, we all know, computers are digital, ie it deals with all digital information, but so far the most widely used CRT monitors (such as televisions) is analog. So in dealing with good data sent to the computer display, you must be a D / A converter (D / A), this treatment resulted in loss of information and display defects. LCD, PDP, HDTV monitor itself is a new generation of digital, the traditional way, the computer graphics card's output (analog) would go through the analog-digital conversion (A / D) can be sent to the display, which in turn resulted in new losses and trouble . with DVI interface, LED display system can be developed directly from the PC, the DVI interface to obtain the number, not the Galaxy dedicated graphics card and the like, do not need a special capture card, PC, are not subject to the restrictions, the absence of D / A conversion process and the MD, to avoid loss of image detail, thus ensuring the computer image on the screen in perfect reproduction. while the DVI is an industry standard so although the bandwidth of up to 83MHZ, also work well. now supports VGA DVI (640 × 480) to HDTV (1920 × 1080) and QXGA (2048 × 1536) all display modes. In addition to using DVI interface, the development of the LED display system, in obtaining reliable data on the basis of the display, but also will be integrated with many important functions such as: ① no data loss, ② is not limited by the PC machine, ③ easy to upgrade, the general video card memory 8M, and the card memory is 128-256M, ④ window position and size of the adjustment; ⑤ frame rate up to 60HZ; ⑥ non-linear adjustment of output, is more suitable for the human eye viewing; ⑦ 100 级 Screen brightness control; ⑧ constant current drive; ⑨ cell plate of red, green and blue light were adjusted to eliminate the mosaic. ( 4) with indoor full color system: the chip display data in addition to completing the allocation of tasks, their identity is to receive 8-bit (8 bit) display data into 12-bit PWM output pulse that allows the display to achieve 4096 (12bit ) gray level control to ensure that the visual non-linear 256 gray scale implementation, to full-color visual effects, can be a fundamental solution to the digital display system because the data transmission system caused by excessive complexity. has the following characteristics: ① simplicity because the system part of the most complex data conversion to the chip internal logic are realized in the form, the system becomes very simple. ② easy maintenance and simplicity of the system is directly related to ease of maintenance, due to eliminating the need for complex control part, system maintenance becomes a junior technical personnel from the work can be completed, which not only reduces the overall maintenance costs, but also improves customer satisfaction. ③ high reliability system control part of the system simply bring about further high reliability, which is mainly because compared to the separation of integrated chip technology has several times the stability of the device technology. ④ cost-effective performance of the system to achieve the most reliable 4096 gray screen color control, image display vivid, natural to achieve the same effect of display control. ⑤ modular, structural design and direction of the current development of the industry consistent with a large screen display system in the body structure using modular design, the system intuitive and easy connection, not only to ensure that the display body size can be adjusted as needed stitching, but the system's installation, commissioning and maintenance has become very easy to monitor the system to minimize the failure rate is not visible. ⑥ modular industrial design system reliability design, replacing the traditional design large number of separate components, the system greatly improved the reliability and stability. ⑦ complete solution, including data source component systems, transmission equipment, data processing, data distribution and software management tools to make the building into a simple LED display standardization. The practical application of process technology in the development and improvement continue to be, has become a most mature, stable, easy to implement system solutions. ⑧ equivalent CRT display LED display most of the core indicators of performance for each primary color (red , green, blue) that is achieved by the gray level of brightness, the display of the current international standard is required for each color to achieve 256 gray vision. dedicated processing chip gray control logic can be output to the gray 4096 and CRT monitors from the phase selection and fitting of 256-level grayscale output, and the overall picture was more clear, realistic and full of appeal. ⑨ high resolution and high refresh rate in addition to gray scale, the display of the other two personality can be indicators of its resolution and refresh rate. As LED display their own characteristics and requirements, the traditional solutions which tend to be the loss of one or two criteria as another indicator of the price increase. As each chip The second data output pin to 1 trillion, far more than the traditional program data output capability, so that the problem be solved fundamentally. The full-color system can support both screen resolution of 1024 × 768 and up 300Hz screen refresh rate, far exceeding the performance of traditional solutions to enable the display stable, no flicker, no tail. (5) constant current drive: The circuit technology is mature and reliable, has been in full-color display on the extensive use of high cost performance, many companies now commonly used for the constant-current driver chips, better way to solve discrete LED tube defects pressure drop and good performance, elimination of mosaic. (6) optical fiber transmission, optical transmission without attenuation Technology: ① the frequency bandwidth of optical fiber transmission, communications capacity. fiber available bandwidth is about 1.25G, frequency bandwidth, increase the scanning frequency and the refresh rate, the company designed LED full color screen refresh frequency ≥ 200Hz / s. ② fiber transmission loss is low, long-distance relay. Its maximum distance is up to 15,000 meters relay to improve the reliability and stability. ③ fiber transmission resistance to electromagnetic interference. fiber is an insulator material, it is not the nature of the lightning interference, ionosphere changes and the interference of sunspot activity, are not subject to electrified railway and high voltage equipment, feeders and other industrial electrical interference. ④ fiber diameter thin, light weight and soft. fiber core diameter is very small, about 0.1mm, it is only one per cent of single-tube coaxial cable; cable diameter is small, 8-core cable cross-section diameter of about 10mm, while the standard coaxial cable to 47mm. use this feature fiber, so little space occupied transmission system . the construction of convenient wiring. ⑤ fiber transmission outstanding addition to the above advantages, it also has strong corrosion resistance, anti-nuclear radiation, energy consumption is small.
