Increasingly rich and colorful TV programs bring more interaction and visual impact to the audience. In recent years, LED display has gradually become the mainstream of the program background. Here are some information and analysis about this technology.
LED display
LED display in the large-scale activities in the television studio and television are increasingly being used, as the stage background, which provides a variety of vivid, dazzling background images and more interactive features, so that the background picture to move also static performances and background integration of people feel a sense of It gives the choreography a larger space for reverie, modern design and the visual impact of the stage, the perfect atmosphere of the site and programs together to achieve the elusive functions and effects of other stage arts equipment. Watch the effects and feelings of the audience on it is very intuitive, as long as the appropriate screen size and pixel pitch and viewing distance, this look directly at the display you can get excellent results. There are some factors to be taken into consideration in the selection and use of the LED display.
The pixel should be as precise as possible
The spacing is the distance between the centers of it adjacent pixels. The smaller the spacing, the more pixels per unit of area, the higher the resolution, the more recent shooting distance, of course, its price is also more expensive. LED display used in the domestic television studio spacing of 6-8 mm. Should be seriously studied the relationship between the resolution and pixel pitch of the signal source, and strive to achieve the resolution to reach the point display, in order to achieve the best results.
Color temperature should be adjusted
The color temperature through the emitter emission spectral shape and the best fit blackbody emission spectral shape is determined by temperature. Studio using the LED display as the background, its color temperature should be consistent with the lighting color temperature within the studio in order to get accurate color reproduction in the shooting. Studio lighting according to program needs, and sometimes use low color temperature lamps 3200K, sometimes using 5600K high color temperature lamps, you need to adjust to the appropriate color temperature, to obtain a satisfactory shooting.
To ensure good usage environment
Product only under favorable conditions of work during the life of the failure rate was low. LED display as the integration of electronic products, it is mainly equipped with the LED controller, switching power supplies, light-emitting devices and other components, but the longevity and stability of all these components are closely related with the operating temperature. If the actual operating temperature exceeds the scope of the use of the product prescribed, not only will shorten the life of the product itself will be subject to serious damage.
The use of LED walls has greatly enriched the display of the program background. They are widely used in LED display as the background, suitable for large scenes, a variety show of the big studios.
