Stage LED display - ledp3 electronic large screen
Green environmental protection has become a major theme in the modern era. The society is advancing, but the environmental pollution is also constantly expanding. Therefore, human beings must protect our homes. Nowadays, all walks of life are also promoting green environmental protection. Products, then how p3 stage LED companies can develop and design p3 stage LED display that will not produce light pollution and waste electric energy, which has become an important product performance that manufacturers must solve.
The p3 stage LED display has been widely used in various corners of the city and has become a unique symbol to enhance the image of the city. However, while it beautifies the image of the city, the strong light of the screen also contributes to the night life of the urban residents. The negative impact. Although the p3 stage LED industry is a “light-forming†industry, the display “lighting†is understandable, but it has been reduced to a new type of pollution “light pollution†from the city's environmental pollution indicators. Therefore, as a company should pay attention to the "light pollution" problem in production, we should control the setting of brightness.
The first method of control: an adjustment system that automatically adjusts the brightness.
Depending on the day and night, a slight change in display brightness can have a significant effect in different locations and time periods. If the playback brightness of the p3 stage LED display is more than 50% of the ambient brightness, we will obviously feel the eye discomfort, which will cause "light pollution."
Then we can use the outdoor brightness acquisition system to collect the ambient brightness at any time, and use the display control system to broadcast the screen by receiving system data and automatically converting it into a suitable brightness by software.
The second control method: multi-level gray scale correction technology.
The ordinary p3 stage LED display system uses an 18-bit color display level, so that in some low gray levels and excessive colors, the color will be very hard, which will cause the color light to be unsuitable. The new p3 stage LED large-screen control system uses a 14-bit color display layer, which greatly improves the hardness of the color, so that people feel soft color when watching, to avoid people's discomfort with light.
In terms of power consumption, although the luminescent materials used in the p3 stage LED display itself are energy-saving, some applications need to be applied in a large display area. Because of long-term use, the overall power consumption is still large because it needs The brightness of the display will be relatively high. Under the influence of these comprehensive factors, the power consumption of the display screen is quite amazing, and the electricity expenses of all the advertising owners will also increase geometrically. Therefore, companies can save energy by using the following five points:
(1) The high-efficiency p3 stage LED can be used, and the light-emitting chip does not cut corners;
(2) Adopt high-efficiency switching power supply to greatly improve power conversion efficiency;
(3) Perform excellent screen heat dissipation design to reduce fan power consumption;
(4) Design a scientific overall circuit scheme to reduce the internal line power consumption;
(5) Automatically adjust the brightness of the outdoor display according to changes in the external environment, thereby achieving the effect of energy saving and emission reduction;
With the development of the p3 stage LED display technology, the p3 stage LED display is increasingly used in large-scale events in TV studios and television broadcasts. As an active backdrop, it provides a variety of vivid and dazzling background images. More interactive features make the background picture dynamic and quiet, so that the performance and the background are integrated, perfectly blending the atmosphere of the scene and the program, realizing the functions and effects that are difficult to achieve in other stage art equipment. However, in order to take advantage of the p3 stage LED display, pay attention to the following aspects in the selection and use process.
First, the shooting distance should be appropriate
The distance between the images is related to the dot pitch and fill factor of the p3 stage LED display. The p3 stage LED display with different dot pitch and different fill factor is suitable for different shooting distances. Take the p3 stage LED display with a dot pitch of 4.25 mm and a fill factor of 60% as an example. The distance between the person being shot and the screen is 4-10 meters, so that you can get a better background image when shooting people. . If the character is too close to the screen, the background will appear grainy when shooting close-ups, and it will also be prone to texture interference.
Second, the point spacing should be as small as possible
The dot pitch is the distance between the center points of adjacent pixels of the p3 stage LED display. The smaller the dot pitch, the more pixels per unit area, the higher the resolution, the closer the shooting distance can be, and of course the more expensive it is. At present, the p3 stage LED display used in domestic TV studios has a dot pitch of 1.5-2.5 mm. It is necessary to carefully study the relationship between the resolution of the signal source and the dot pitch, and strive to achieve consistent resolution and point-to-point display. Thereby achieving a satisfactory display effect.
Third, color temperature adjustment
When the studio uses the p3 stage LED large screen as the background, its color temperature should be consistent with the color temperature of the studio, in order to get accurate color reproduction during shooting. The lighting of the studio is sometimes based on the demand of the program, sometimes using 3200K low color temperature lamps, sometimes using 5600K high color temperature lamps, and the p3 stage LED display needs to be adjusted to the corresponding color temperature to obtain satisfactory shooting results.
Fourth, to ensure a good use of the environment
The life and stability of the p3 stage LED large screen are closely related to the operating temperature. If the actual working temperature exceeds the scope of use specified by the product, not only will its life be shortened, but the product itself will be severely damaged. In addition, the threat of dust cannot be ignored. Too much dust will cause the thermal stability of the p3 stage LED screen to drop or even cause leakage. In severe cases, it will cause burns; dust will absorb moisture, which will corrode electronic circuits, causing some short-circuit problems that are difficult to check, so pay attention to keeping the studio. clean.
