As the P4.81 rental LED display is more and more widely used, we see and even use them in various stage scenes every day. The P4.81 rental LED display with its large screen and high-definition resolution, It has become the main display solution for creating immersive scenes, and is also very popular in exhibition halls, exhibition halls and other scenes. So what factors should be considered when choosing a P4.81 rental LED display? Let’s take a look.

Factors to consider when choosing a P4.81 rental LED display:

  1. Brightness

The number of brightness levels that can be distinguished from the darkest to the brightest in the same level of brightness of the LED display. Grayscale, also known as gradation or grayscale, refers to the degree of brightness and darkness. For digital display technology, grayscale is the determinant of the number of displayed colors. Generally speaking, the higher the gray level of the LED display, the richer the color and the brighter the color; on the contrary, the display color is single and the change is simple.

At present, the domestic LED display mainly adopts an 8-bit processing system, that is, 256 (28) levels of gray. A simple understanding is that there are 256 brightness changes from black to white. Using RGB three primary colors can form 256×256×256=16777216 colors. The international brand display screen mainly adopts a 10-bit processing system, that is, 1024 gray levels, and the three primary colors of RGB can form 1.07 billion colors.

  1. Wavelength

The wavelength determines the dynamic color gamut range of the display. The three colors of the LED full-color display are all measured by wavelength. A high-quality LED full-color display should have a wide color gamut.

  1. Frame change frequency

The frequency of updating the screen information of the LED display. Generally, it is 25Hz, 30Hz, 50Hz, 60Hz, etc. The higher the frame changing frequency, the better the continuity of the changed image.

  1. Refresh frequency

The reciprocal of the time required for a frame to be displayed, and the display screen is regarded as a light source, which is the flickering frequency of the light source. We can directly test the flickering frequency of the light source of the display screen with an instrument similar to a “photosensitive frequency meter” to reflect this indicator.

The LED display shows the number of times the data is repeated per second. Usually 60Hz, 120Hz, 240Hz, etc., so it is necessary to maximize the refresh frequency to ensure the stability of the display screen.

However, as it is used on the stage, we actually have some points that need special attention. Because the stage led display is actually an LED display that is put into the stage background, the biggest feature of the stage rental led display is that it provides a rich stage background. The display functions to create spectacular and modern spectacles.

Because the stage rental led display is generally not only the main screen of the stage, but also consists of auxiliary screens and extended screens. The function of the main screen is to broadcast and playback the content on the stage. Typically, a monitor with a slightly smaller pitch is chosen. The point distance is usually within P5, and the larger the area, the better the effect.

In this way, the scene of the rental led display screen on the stage can be displayed smoothly in front of the audience. As mentioned earlier, there are usually additional screens next to the main screen. The additional screen is not necessarily a rental display, but may also be a curved screen, a transparent screen, a cylindrical LED display, etc.

Of course, if the budget is limited, you can also use a larger dot pitch, such as the P6 stage rental led display. After all, the extended screen of the stage video generally uses a very large stage, and it is precisely because of this that all the audience can see everything on the stage clearly.

In addition to selecting the main body of the stage rental display, the rental display must also select the corresponding LED control system. Generally speaking, the stage rental led display has a large display area, high pixels, and a large number of transmission cards. Sometimes multiple controller cards are required to control cascaded splices.

If you want a better led display, you usually need to use a video processor. This allows for patching and clipping of video, enabling multiple windows. The image is displayed in the image, with higher scalability, and the video effect is more detailed and soft.
