With the development of electronic skills and video skills, the use of various impression devices in stage play is increasing, which promotes the development of stage play art. LED electronic screen is a technology product integrating optoelectronic skills, video skills, computer skills and microelectronics skills. LED display screen has been widely used in modern stage play because of its strong function.
LED is a kind of current light-emitting device, which converts electric energy into light energy through current generation light source. The difference of data determines the luminous color and luminous intensity after it passes through the current. Red, green and blue are the three primary colors, from which the three colors are adjustable and arbitrary. It is led dot matrix layout that light-emitting diodes are arrayed arbitrarily in a certain interval, that is, LED electronic display screen. The brightness of each LED in the LED display screen constitutes pictures and words on the LED electronic display screen.
The factors that affect the quality of the display screen include brightness, color mixing, viewing angle, uniformity, device technology and non-linear calibration. The smaller the point to point isolation of each LED in the LED electronic screen, the clearer the picture resolution, that is, the higher the pixel. The more the brightness of each LED changes under the control of the circuit, the more delicate the picture will be. Through the computer multimedia skills, we can input various forms of information sources into the computer network system. Such as TV signal, video camera signal, video recorder signal, computer animation and text information. The content of LED electronic screen in the video condition is completely corresponding to the TV picture of these signal sources. LED display with its high brightness, low power consumption, stable function, long service life, display area can be arbitrarily assembled by the unit module according to the needs, has become the first choice of impression equipment in modern stage play.
The function and significance of LED display screen in stage performance
Now the LED electronic display used in stage play is very popular. Its expressive power is rich: it can imitate the real scene and reproduce the nature. It can also present functional pictures, and can also be used to display materials and so on. It has the sensitivity and virtuality that the traditional scenery can’t compare with, and has some light source characteristics of the lighting system. For example, the large screen is made of light-emitting diodes. Through its own light source function, it can imitate the actual space appearance and convey the role of lights. Therefore, some lamp design also advocates the use of it in connection with the lamp. The rest it conveys is now difficult to define with traditional scenery or lights, just like the role of computer lights on the sky, with similar characteristics.
1. Rich content
In the past stage play, the function of LED display screen is relatively simple, mainly to display video information and synchronous video pictures. In the stage acting at that time, the stage workers did not belong to the field of dance beauty, just regarded it as a big TV on the stage. Nowadays, as an extension and compensation of stage play, LED display enriches the content of play and provides the audience with information beyond play itself. Through the large LED screen, the audience got rid of the single and fixed perspective, and even could see their own reactions, which also constituted a certain freshness in vision.
