What are the technical requirements for indoor LED display screens?

To create a high-definition and realistic digital background, indoor LED displays must meet the following six core technical requirements:

1. Extremely delicate pixel spacing

Live streaming rooms usually have limited space, and the distance between the camera and the background screen is relatively close. In order to prevent obvious graininess in the image, а small pitch LED display screen must be selected. В настоящий момент, mainstream live streaming rooms usually require pixel spacing below P1.5, and high-end studios even use ultra small spacing ranging from P0.62 to P0.93. Small spacing can ensure that the background remains delicate and flawless when the anchor takes close-up shots, eliminating the interference of grid feeling.

2. Ultra high refresh rate rejects scan lines

Under the lens, ordinary display screens are prone to water ripples (moir é patterns) and black stripes. The refresh rate of the LED display screen in the live broadcast room must be above 3840Hz, and some high-end configurations even need to reach 7680Hz.

3. High grayscale, restore image details

Grayscale determines the richness of color transitions and dark details. The lighting environment in the live broadcast room is complex, and the display screen must maintain high grayscale even at low brightness (usually requiring 14-16 биты).

4. Flexible and adjustable wide color temperature

The color temperature of the lighting in the live broadcast room often needs to switch between cool white light and warm light according to the theme. Следовательно, the color temperature of LED displays must have an extremely wide adjustment range (usually flexible and adjustable between 2000K and 12000K), and support fine white balance correction.

5. Advanced packaging technology

Ensuring stability currently relies mainly on different packaging technologies for indoor micro pitch displays. The traditional SMD packaging technology is highly mature, while the new COB fully inverted chip packaging and MIP technology are becoming increasingly popular in live streaming rooms. Especially with COB packaging, it not only provides stronger surface protection, resistance to bumps, moisture and water, but also achieves ultra-high ink consistency, effectively solving the problem of reflection and allowing the screen to maintain a pure black phase even under complex stage lighting.

6. Ultra large visual angle and energy-saving design

During the live broadcast, the camera position often switches between left and right swing arms or multiple angles. This requires the display screen to have an ultra wide viewing angle (such as a horizontal/vertical 170 ° viewing angle)

В итоге, the selection of LED display screens in live streaming rooms is not simply about “looking bright”, but rather a comprehensive evaluation of multidimensional technical indicators such as pixel spacing, Частота обновления, and grayscale.
