Small pitches are becoming more and more popular, but the small-pitch LED display can not achieve the ideal display effect without the auxiliary role of the video processor. Unlike outdoor LED large screens, small-pitch LEDs are subject to many restrictions in terms of image display.
First, the brightness of the environment is different. The brightness of the indoor environment is low, so the brightness of the LED screen is not required to be as high as outdoors. This requires the video processor to have better image quality improvement capabilities, especially more advanced image scaling processing algorithms, so as to ensure that high-definition video images can maintain image detail clarity and gray levels after scaling processing. Secondly, there must be abundant image adjustment options and adjustment effects, especially the adjustment of image brightness, contrast, and low-gray processing, so as to ensure the output of soft, clear and layered pictures under the indoor light environment of the screen.
Second, the indoor display is limited by the area of ​​the venue, and it is required to display as high-definition videos and images as possible within the limited display area. This requires the video processor to have higher resolution image output capabilities, higher resolution and more video image input capabilities.
Third, the traditional applications of indoor large screens are large screen displays for monitoring, command, and control occasions. These applications require large screens with high definition, multiple input signals, and more real-time video window screens, as well as flexible and fast access to these screens Control and management.
LED video processor is the witness and key equipment of the birth, growth and maturity of LED full-color display. The quality of LED video processor directly affects the display effect of LED display. So from the user's perspective, how do you choose a suitable processor?
Taking the control room application as an example, the control room is one of the most demanding environments for video wall processors. In many cases, the real-time and integrity of the signal will affect the accuracy of decision making. Therefore, in addition to considering the stability of the product in the selection process, the user also needs to conduct a comprehensive review of the real-time processing capabilities of multiple input signal sources, whether they are easy to use, and the specific application environment.
When choosing a processor, the first consideration is to be able to reproduce the signal source in the system. This is a basic requirement of every video system used for decision-making, because distortion of image resolution conversion may cause content to be misinterpreted. Second, unstable video performance, such as dropped frames or freeze frames, will distract users and hinder correct content analysis; again, control rooms will often use multiple signal source types, and the correct processor must be compatible These signal sources; Finally, the flexibility of configuration must also be considered. Because the number of inputs, input types, and screen arrangement of the video wall are different in each project, the video wall processor needs to be flexible to configure to meet these specific applications Demand.
In addition, in the design of an excellent control room solution, the specific application environment and how to use it need to be considered. For example, the needs of utility management centers are not the same as those of military agencies. Understanding the type of information you need to display and how to present it is the first step in choosing a video wall processor.
Control room usually involves and uses multiple signal source types. Compatibility with control room-specific signal types and the ability to display a large number of source windows ensures that control room staff can see important information that can help them be more efficient. jobs. In addition, as many organizations choose to display HDMI satellite broadcast signals or Blu-ray content, compliance with the HDCP standard is becoming a requirement.
An excellent solution must consider both the requirements for implementation and the new requirements that may arise in the future, such as the convenience of operation, display effects, and viewing comfort involved in the process of signal access, processing, scheduling, and display. System maintenance and expansion are all taken into consideration when selecting the video wall processor.
Pulverizer Machine
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
