Functional advantages of LED active luminous traffic signs | Best price led traffic signs manufacturers
Best price led traffic signs manufacturers LED active light-emitting road traffic signs (hereinafter referred to as "active light-emitting signs") are more and more popular because of their superior performance and quality in special traffic environments and bad weather compared to ordinary retroreflective signs. It is widely used in traffic safety engineering. Traffic language information such as road conditions, risk factors, management instructions, etc., are reflected in the traffic sign layout through the use of standard traffic language formats, so that road traffic participants can identify them in a timely, accurate and effective manner, aiming to achieve road traffic safety, Efficient and orderly. According to the conclusion of the special study: the human body’s sense of perception is formed by the five senses of sight, hearing, smell, touch and taste, of which visual cognition accounts for as much as 83%. Therefore, as a visual carrier of traffic language, traffic signs can ensure effective recognition in all-weather and harsh environments, and their importance to drivers is self-evident. The working principle of ordinary retroreflective traffic signs: a beam of incident light illuminates the reflective material from the front, is internally refracted, and then penetrates the reflective material in the reverse direction, and reflects back in the direction parallel to the incident light, so that the light in a certain observation area The observer captures the reflected light, also known as "retro-reflection", which belongs to the category of passive light sources. Juli Technology is mainly engaged in the whole process of design, R&D, production, sales and service of road traffic luminous signs, intelligent traffic guidance screens, variable/tidal lanes, all-point information screens, intelligent composite screens and warning lamps series. The company has always Adhering to the business philosophy of "professionali

Points to consider when choosing an LED display
Now, with the advancement of social technology and the development of outdoor advertising, people's requirements for outdoor media are getting higher and higher, so large LED screens are beginning to emerge. The large-scale LED display is a perfect combination of technology and media, and its product applications involve financial securities, sports, airports, railways, stations, highway transportation, commercial advertising, post and telecommunications and many other fields. How to choose a high-quality LED large screen is a problem that many buyers need to consider. Let's talk about this problem from the key aspects of LED large screens: 1. Flatness The surface flatness of the LED display should be within ±1mm to ensure that the displayed image is not distorted, and local protrusions or recesses will cause a blind angle in the viewing angle of the LED display. The quality of flatness is mainly determined by the production process. 2. Brightness and viewing angle Brightness and viewing angle The brightness of the indoor full-color LED display must be above 1800cd/m2, the brightness of the outdoor full-color LED display must be above 5000cd/m2, and the brightness of the outdoor led strip screen must be above 2000cd/m2 to ensure The normal brightness of the LED display is required, otherwise it will be difficult to see the displayed content because the brightness is too low. The brightness is mainly determined by the quality of the LED die. The size of the viewing angle directly determines the audience of the LED display, so the larger the better, the size of the viewing angle is mainly determined by the packaging method of the die. Three, white balance effect White balance effect The white balance effect is one of the most important indicators of the LED display. In color science, pure white will be displayed when the ratio of the three primary colors of red, green and blue is 3:6:1. If there is a slight deviation in the actual rati

Things to pay attention to when choosing LED display
The LED display has the advantages of ultra-high brightness and seamless splicing. If the LED pitch is small, the picture will be clearer and more delicate. Among the many material display screens, LED display screens are relatively environmentally friendly and energy-saving. If there is a demand in this regard, how to choose a display? 1. Seamless splicing, large screens are all spliced together, but there are many materials for splicing screens, and the advantage of LED displays is that splicing is seamless. If it is an LCD splicing screen, splicing is very obvious, so seamless splicing is considered one of the advantages of led display screens. 2. Super high brightness. If the LED display is different from other displays, it must be the ultra-high brightness of the LED display. LED display screens can also display normally under direct sunlight, becoming the dominant outdoor display screen. Brightness is high; outdoor displays are generally large screens, so there are certain requirements for brightness, LED displays are very suitable. 3. Customized size, various shapes. The led display screen can be made into various sizes, and the shape of the display screen can be flexibly changed according to different use environments. The special-shaped led screen can also be customized to attract pedestrians with a peculiar appearance. 4. Energy saving and environmental protection, the energy consumption of LED large screen display is about 30% lower than other displays of the same area.

Seamless splicing, large screens are all made of splicing, but splicing screens have many materials, and the advantage of led display is that splicing is seamless. If it is LCD splicing screen, the splicing is very obvious, so seamless splicing is considered One of the advantages of led display. 2. Ultra-high brightness. If what distinguishes the LED display from other displays, it must be the ultra-high brightness of the LED display. The LED display can display normally under direct sunlight and become the dominant outdoor display. It is high brightness; outdoor displays are generally large screens, so there are certain requirements for brightness, and LED displays are very suitable. 3. Custom size, various shapes. The led display screen can be made in various sizes, and the shape of the display screen can be flexibly changed according to the different use environment, or the led special-shaped screen can be customized, and the strange appearance can be used to attract pedestrians. 4. Energy saving and environmental protection, the energy consumption of LED large screen display is about 30% lower than other displays in the same area.

Introduction to popular science about led display
The basic composition of LED display: 1. Asynchronous screen: It is generally composed of display unit board (module), bar screen card, switching power supply, and HUB board (optional). Connect to the computer through a serial cable, change the display text, and then work without the computer. 2. Synchronization screen: The synchronization screen system is more complex, the system can be large or small, generally composed of a computer, DVI graphics card, data sending card, synchronous data receiving card, HUB board, network cable, LED display, etc. The system always needs an online computer to work, and the image and text on the computer are displayed on the large LED screen. three. Terms and concepts involved in LED display 1. Pixel: It is the smallest imaging unit of the LED display. Commonly known as "dot" or "pixel". 2. Display module: It is composed of several display pixels, which are the smallest unit of the LED display screen independently in structure. · The indoor screen uses 8x8 display modules, that is, each display module has 64 pixels · The outdoor screen uses a single lamp bead, usually one pixel of the module is composed of 1-3 lamp beads of the same or different colors. 3. Display module: The independent unit of the LED display screen determined by the circuit and the installation structure and has the display function. Simply put, in order to facilitate assembly and display, the semi-finished products shipped from the factory are usually provided in the form of display modules, and multiple display modules and display drivers are built together. Indoor screens are commonly called "unit boards"; outdoor screens are commonly called "modules". Several modules are combined with chassis, fans, and power supplies to form a "box", which is mostly used for large full-color screens. · Indoor screen unit boards usually have 64x32 (64 columns and 32 row
