Outdoor P10LED full color display parameter analysis

As the market's demand for outdoor advertising continues to increase, outdoor applications are rapidly expanding. Facing the complicated products on the market, how can industry users choose products that satisfy themselves? Understanding the LED display parameters is the first prerequisite.

1. Sharpness: According to the most suitable viewing distance point to determine the screen area required, the resolution "40000 pixels/m2" suitable distance is 5-50 meters; adopt the latest technology 16-bit data interface to further improve the clarity of the screen .

2. Brightness: The screen brightness is designed to be more than 2500cd/m2, which can not only ensure the vivid color and clear image when the indoor full-color LED display is normally used, but also ensure that the LED display can be used when the lamp attenuation exceeds 30%. Sufficient brightness and sharpness of the video image. Refresh rate: between the processor and the screen using ultra-five twisted shielded cable, configuration of high-performance control IC, you can put the screen high refresh rate design in 1000HZ, to ensure that there is no ripple and flashing video playback, all Low digital loss, anti-electromagnetic interference. Power supply and signal transmission methods: Because of the importance of full-color LED displays, the power supply and signal transmission must be specially processed technically, using high-quality, high-grade connector designs. Further control the failure caused by various lifting forces at the connector.

3. Control mode: The independently designed control system is selected and 240 hours of uninterrupted power-on aging screening is selected to select a highly reliable control system. In addition, dual redundant hot backup is used in the control mode. Once a problem occurs, it is immediately accessed by another signal line, and normal operation continues smoothly.

4, raw materials: LED display screen all raw materials are selected brand-name quality products, the most important LED lights use high-quality LED lights;

5. Aging process of the third-grade products: firstly, aging the modules produced by the automated assembly line for 24 hours, then aging the individual boxes for 48 hours, and finally simulating the on-site assembly of the finished product display panel for 72 consecutive hours of electrical aging; The arrival arrived at the site where it was assembled.

6, product quality control: all products in strict accordance with the ISO9001-2000 quality certification system documents for product manufacturing. (See quality certification), will be in strict accordance with the IP65 waterproof test to achieve complete waterproof effect. LED display installation and debugging: In strict accordance with the design program for LED display installation and commissioning, the installation level to reach the C level or above (the highest level of LED display installation).

7, the latest system software (prepared in the screen and then applied): The operating system uses Windows XP and supports Microsoft's latest series of Windows products. All application software uses Windows as the operating platform and friendly interface. The playback software has a rich clock function. It can display the current date and current time. The display clock synchronized with the computer's time can be a simulated clock or a digital clock. The software uses a comprehensive threading technology to play text, animations, clocks, photos, audios, etc. in multi-threads while playing software.

8, a complete system function design (prepared in the screen and then apply): The system can meet the assembly, performance, television broadcast and advertising broadcast requirements. This project LED display system has multimedia, multi-channel, can communicate high-speed communication data and video interface in real time, can easily introduce various forms of information sources into the computer network system, to achieve a unified control of various audio and video input. The detailed functions are as follows:

9, video playback function can display true color dynamic video images; can be high-fidelity broadcast CCTV, a variety of television programs; a variety of video signal input and output interfaces: composite video, Y / C video (S_Video), YpbPr, VGA (RGBHV) , DVI, HDMI, and SDI (HDSDI); Can play video programs such as VCRs, DVD players (VCD, DVD, LD) with high fidelity; has the ability to superimpose text, animation, and still pictures on the video screen; Implement real-time editing and playback functions such as panoramas, close-ups, slow motions, and special effects. Brightness, contrast, saturation, color can be adjusted by software, adjustment range is 256; with image freeze function; with video overlay (VGA + Video), video (Video), VGA three display modes; with horizontal / vertical Position compensation function; with display synchronization function.

10, computer graphics and text information playback function can display a variety of computer information, text, graphics, drawings and two, three-dimensional animation, etc.; have a wealth of playback methods, display scrolling information, notifications, slogans, slogans, etc., storage data information capacity. The display screen can open multiple windows, display calendars, clocks, and insert single-stream texts. There are many kinds of Chinese fonts and fonts to choose from. You can also input foreign languages ​​such as English, Spanish, French, German, Greek, Japanese, Latin, and Russian. The broadcast system has multimedia software that can flexibly input and broadcast a variety of information. There are more than 20 kinds of broadcast methods, such as scrolling, scrolling up and down, pushing around, pushing up and down, pushing diagonally, spreading, fan type, rotation, and zoom. Through the network connection, the network data information is displayed. It is equipped with a network interface, which can be networked with computers, share network resources, and has a standard audio signal output interface for audio and video synchronization.
