"Talk about what is a static screen, what is a scanning screen?"
First, what is a real pixel screen, what is a virtual screen?
The real pixel screen corresponds to the virtual screen. To put it simply, a real pixel screen means that each of the red, green and blue light-emitting tubes constituting the LED display finally participates in imaging of only one pixel to obtain sufficient brightness.
The virtual screen uses a software algorithm to control the LED of each color to finally participate in the imaging of multiple adjacent pixels, so that a larger resolution can be achieved with fewer lamps, and the display resolution can be increased by about four times. .
Second, what is a static screen, what is a scanning screen?
The static screen corresponds to the scan screen. The static screen refers to the LED display screen displaying the text, image and video. The light points on the LED display screen are illuminated at the same time; instead of the same as the scan screen Using the visual persistence characteristics of the human eye, each row of the LED display is illuminated in a short period of time. As is known, the LED display is driven by the duty cycle, so the brightness of the display has a great relationship with the time period of lighting. Therefore, in the case where the brightness of the same light-emitting tube is the same, the static screen is higher than the brightness of the scanning screen, so the static screen is often used in the case where the outdoor brightness is required to be high-brightness, and the scanning screen is often used indoors where the brightness is not high. Next, to save drive costs.
Third, LED display using virtual display technology will reduce the brightness?
LED linear virtual technology is a patented technology developed for the need to reduce the number of lamps used under the same resolution conditions. The virtual technology is the application software algorithm to make full use of the pixel lamps on the LED display. In combination with the duty cycle output characteristic of the light-emitting diode and the visual persistence characteristic of the human eye, the lamp is time-divisionally and segmentally displayed with different brightness, so that about four times the content can be displayed under the same number of pixels. . Of course, the use of virtual technology will cause a certain degree of brightness reduction. In order to solve the defect of brightness reduction, the linear virtual technology introduced by Zhongqing makes full use of Zhongqing's control system, control chip and constant current chip characteristics to optimize the virtual algorithm. The brightness loss of the entire screen is extremely small and hardly discernible to the naked eye.
