High-definition outdoor full-color LED display, full-color outdoor LED display, and energy-saving outdoor LED display are very popular in the full-color LED display market. Let's take a look at their respective advantages.
1. High-definition outdoor full-color LED display products have the following advantages:
1) It has the characteristics of liquidity, compulsoryness, pertinence and effectiveness.
2) Program advantages. Self-made programs, instant broadcast, and rich content; not only advertisements, but also programs, including special topics, columns, variety shows, animations, radio dramas, TV dramas, and advertisements inserted between programs.
3) Location advantage. It is mainly installed in shopping malls and other areas where traffic is concentrated. Among them, high-definition outdoor full-color LED display is installed in landmark areas, and its propagation effect is more shocking and mandatory.
2. Outdoor full-color LED display products have the following advantages:
First, have a broad perspective. The outdoor surface mount full-color screen has a wide viewing angle of more than 110 degrees in both horizontal and vertical directions. This is particularly advantageous in some application places, such as building screens, outdoor LED display screens hung at a high altitude, which require a wider viewing angle to make the advertisement display better.
Second, it has a very good light distribution. The full-color SMD has a three-in-one design structure, and the three chips of red, green, and blue are all in a bracket bowl, so the matching consistency of the three brightnesses of red, green, and blue at different angles is highly consistent, which makes The outdoor full-color surface-mount LED display has a good consistency of brightness matching at any angle, and the colors are more realistic.
Third, the effect of light mixing is also better. Because the design structure is three-in-one, the three chips are very close to each other, and the light is mixed in the same bracket bowl instead of the three discrete elliptical LEDs, so the red, green, and blue mixed light effect is better than the direct insertion elliptical LED Screen, especially suitable for close viewing.
Fourth, it has high contrast. Due to the three-in-one design structure, the full-color SMD has a small size, so the light-emitting area is small and the black area is large, which improves the contrast of the LED display.
Fifth, use automated production. Surface mount LED can use automatic placement machine for automatic placement, with high production efficiency. The circuit design of the LED outdoor surface-mount display module can realize the combination of the lamp board and the driving board, which reduces the cost, improves the reliability, and improves the production efficiency. In addition, automated patch production can also improve the vertical accuracy of SMD on the circuit board, overcoming the vertical accuracy problem of in-line elliptical LEDs on the circuit board, thereby ensuring better optical effects.
Sixth, the cabinet is light in weight. The aluminum alloy material box structure design is very light; it is not easy to deform and easy to assemble and flat. Suitable for rental companies, LED rental screens, and mobile media; column installation or wall installation alleviates the pressure of the screen on the steel structure.
Seventh, glue-free. Previously, because the brightness of surface-mount LEDs was low, and the waterproof, moisture-proof, and ultraviolet-proof functions could not meet the requirements of harsh outdoor environments, outdoor full-color displays were the world of in-line LED devices. Full-color surface-mount LED display can only be used in large numbers indoors. With the advancement of LED chip technology and LED packaging technology, the brightness and protection level of SMD have been able to meet the needs of outdoor applications, and have obtained faster applications.
In addition, the surface of the LED surface-mounted full-color display screen is smoother, with even brightness and better saturation, and is suitable for all fields. In the future, it will become the mainstream application of outdoor display systems.
3. Energy-saving outdoor full-color LED display products have the following advantages:
1) Outdoor full-color LED display media is widely used in public places, advertising, urban road networks, urban parking lots, railways, subways and other traffic guidance systems, highways, etc.
2) Using VGA synchronization technology, the large screen content is synchronized with CRT, and the replacement of advertising content is simple and convenient; large screen, super visual, high brightness and long life.
3) Variety of display modes (graphics, text, 3D, 2D animation, TV screen, etc.).
4) It can improve the city's technological level, enrich the cultural life of urban residents, and make it easier for residents to receive.
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
