LED display technology advantage

(1) The quality imported LED die production of full-color display: viewing angle, low power consumption, color uniform, ultra-thin screen thickness, the screen body weight is light, low failure rate, easy maintenance advantages.

(2) using the PCTV card: The card is a high performance set display, capture, video capture features multimedia graphics card, the card with a Studio editing software. Studio is an award-winning software company of Pinnacle Systems, Compared with the existing ordinary General Multimedia Card

It has the following advantages:

① own PC, making digital movies, capture video, edit, and add the style of title, conversion, and even their own songs as well as digital video production narrative.

② Studio allows the user to select the output video MPEG or AVI file format and stored into the CD tray, or display on a Web site, or create video email. Studio and Pinnacle Systems company capture device, video capture becomes easy never seen before.

③ Studio application software like a VCR from the easy to use good, better, best quality in the form, and calculated that the computer can store video Studio automatically discover and record the scene changes, the editing becomes easy

④ use Studio to create a fast and interactive process. Using the real-time preview window preview of the film can be edited at any time, that is to see that income.

⑤ If you do not like the title or the effect, you can make a change and you can immediately see this change, video editing has never been so fast and interesting. Freely enough personalized, also has the effect of background music, voice-overs and other.

(3) using the latest DVI interface technology: DVI Interface (Digital Visual Interface) is a PC and a digital flat-panel displays (including) the industry-standard interface, as we all know, computer is digital, it handled all digital , but so far the most widely CRT monitor (TV) analog. therefore in the computer-processed data is sent to the monitor display, you must do a number D / A conversion (D / A), this treatment defects that resulted in the loss of information and display new generation of LCD, PDP, HDTV display is digital, the traditional way, the computer graphics card output (analog) would go after the conversion of the analog-to-digital (A / D) can be sent to the display, which in turn caused the loss and trouble using the DVI interface, LED display system developed directly from the PC, DVI interface fetch, no Galaxy card dedicated graphics card, do not need special acquisition card, free from the constraints of a PC, D / A and MD conversion process, to avoid the loss of image detail, in order to ensure a perfect reproduction of the computer image display. simultaneously DVI is the industry standard, so although the bandwidth up to 83MHZ, can also work well now DVI supports VGA (640 × 480) to HDTV (1920 × 1080) and QXGA (2048 × 1536) of all display modes. addition to the DVI interface, the development of the LED display system, to obtain a stable and reliable display data based on, but also of the many important functions integrated
For example: ① no data loss, (2) are not subject to the PC limit, ③ convenient upgrade generally display card memory is 8M, the 128-256M of memory card ④ window position and size adjustments; ⑤ frame rate up to 60HZ; ⑥ non- linear regulator output, more suitable for the human eye; ⑦ 100 Screen brightness control; ⑧ constant current driver; ⑨ cell plate of red, green, and blue color brightness are adjustable to eliminate mosaic.

(4) indoor full color system: the chip to display data to complete the assigned task, its characteristics will receive eight (8 bit) data into 12-bit PWM output pulse that allows the display to achieve 4096 ( 12bit) level grayscale control to ensure the realization of the the nonlinear 256 visual gray achieve full true color visual effects can fundamentally solve the digital display system due to the complex system of data transmission caused by excessive.

Has the following characteristics:
① simplicity of the system the most complex of the data conversion section is realized in the form of a chip-internal logic so that the system becomes very simple.

② directly related to the ease of maintenance and simplicity is the ease of maintenance of the system, eliminating the need for complex control part, system maintenance becomes a work can be completed by the primary technical staff, which not only reduces the overall maintenance costs improve user satisfaction.

The simplicity of the control section (3) High reliability systems further bring the high reliability of the system, which also mainly because integrated chip technology compared to the separation device having multiple stability.

④ high cost system is the most reliable performance to achieve the 4096 gray of the primary colors of the screen control the image display lifelike, naturally, the same display control effect.

(5) unit the structured design consistent with the current direction of development of the industry, large-scale display system in the unit design screen structure, the system intuitive and easy connection, not only to ensure that the size of the display can be adjusted as needed stitching and the installation, commissioning and maintenance of the system becomes extremely simple, and thus minimize the display system is not visible failure rate.

⑥ industrialized reliability design unit design, replacing the traditional design of a large number of discrete devices, greatly improve the reliability and stability of the system.

⑦ comprehensive plan component systems containing the data source, transmission equipment, data processing, data distribution and software management tools, LED display construction becomes simple standardized development and improvement of the technology continue to be in the actual application process, has become a the most mature, stable, easy to implement system solutions.

⑧ equivalent CRT display LED display the most core performance index is gray i.e. luminance level for each primary color (red, green, blue) are achieved, the current the international display standard requires that each primary color to achieve visual 256 grayscale. dedicated the grayscale control chip built-processing logic can output up to 4096 grayscale and selected from 256 grayscale output fitting CRT monitors, so that the overall image more clear, realistic and contagious .

In addition to the gray scale the ⑨ high resolution and high refresh rate, two performance indicators display resolution and refresh frequency due to the characteristics and requirements of the LED display, the traditional solution is often to the loss of which one or two standards as another indicator of the increased consideration. due to each pin of the chip per second data output to reach 1 trillion, far more than the traditional program data output capability, so that the problem fundamentally be resolved this full-color system can simultaneously support a screen resolution of 1024 × 768 and up to 300Hz screen refresh rate, and far exceeds the performance of traditional solutions, so that the display is stable, no flicker, no tailing.

(5) constant current drive: The circuit technology is mature and reliable operation, has been widely used on a full-color display, high performance and low cost, many companies used constant current driver chip, the better way to solve the the LED tube voltage drop across discrete The nature of the defect and good performance, eliminate mosaic.

(6) the optical transmission, optical transmission technology that does not decay:

① fiber transmission bandwidth, large capacity communication. The fiber available bandwidth is about 1.25G frequency bandwidth, improved scanning frequency and refresh rate, the company designed the full-color LED screen refresh rate ≥ 200Hz / s.

② low-loss optical fiber transmission, long distance relay. Maximum repeater distance of up to 15,000 meters, and to improve the reliability and stability.

Immunity to electromagnetic interference (3) optical fiber transmission fiber is an insulator material, which is not natural lightning interference ionosphere changes in sunspot activity interference, not the electrified railway feed wire and high-voltage equipment and industrial electrical interference.

④ fiber diameter is small, light weight, soft fiber core diameter is very thin, about 0.1mm, it is only one percent of the single tube of the coaxial cable; the diameter of the cable is also small, the cross-sectional diameter of 8-core optical fiber cable about 10mm, standard coaxial cable to 47mm. use of this characteristic of the fiber-optic transmission systems share space. wiring quick and easy construction.

In addition to the above outstanding advantages, (5) optical fiber transmission also has the advantage of corrosion-resistant and strong anti-nuclear radiation, energy consumption is small.
