I believe many people in the industry know that the small-pitch LED display itself has high brightness, wide color gamut, high contrast, super display effect, etc... But it is also because of these functions that it is widely liked by the public and has been highly recognized by us . So the question is, how does the small-pitch LED display quickly enter the indoor application market? What kind of skills does it need in such an environment? Next, the editor of LCF will share with you:


1. Reduce the dead light rate of the display lights to ensure the stability of the screen


The dead light rate of traditional LED displays is 1 in 10,000 in the industry standard, but small-pitch LED small displays still cannot do it for the time being. The display is simply unreadable. Therefore, the dead light rate of the small-pitch LED display must be controlled at 1/100,000 or even 1/10,000,000 to meet the needs of long-term use. Otherwise, if a large number of dead lights are displayed for a period of time, users must not bearable.


2. Complete low light and high gray


Many people know that human body induction lights are different from outdoor displays that require high brightness, refresh rate and energy-saving requirements. Indoor displays need to lower the brightness. Tests have shown that from the perspective of human eye sensitivity, LED (automatic light source) The brightness is twice that of the forced luminous source. In terms of detailed data, the best brightness of small-pitch LEDs entering the room is 200-400cd/m2.

3. The standard resolution of the signal source


Unlike outdoor displays, outdoor advertisers will select suitable content and displays based on the resolution of the display screen. Indoor display signal sources have certain specifications. As an LED display manufacturer, they cannot require access to indoor signal sources. It is necessary to get used to the resolution of the display screen, but to get used to the needs of indoor signal sources, plan and ensure the corresponding resolution, and then meet the needs of users as much as possible. Fortunately, through more than a year of guidance on indoor LED display products and understanding of customer needs, our company has completed this change and greatly reached the needs of the majority of users.


4. System access and display control supporting multi-signal and complex signals


Compared with outdoor display signals, small-pitch LEDE display signals are characterized by multi-signal access and complex signal access, such as multi-location video conferences, which require long-distance access signals, local access signals, and multi-user access. In addition, it has been shown by tests that simply implementing multi-signal access through the split screen scheme will reduce the signal standard. Therefore, how to deal with multi-signal and complex signal access problems also requires the technical support of small-pitch LEDs.


5. Complete seamless patchwork and high-speed proofreading


The biggest advantage of small-pitch LED displays is that they are seamless, but they have higher requirements when splicing. For the liquid crystal, as long as the seams are uniform, there is no problem, and the seams are not noticeable. But the small spacing of LEDs cannot be like this. If the modules are squeezed too tightly, bright lines will appear, and if the modules are separated, dark lines will appear. So it is not easy to splicing well. Therefore, the craftsmanship and proofreading skills of the cabinet, as well as the guarantee and good combination of power, all need to be guaranteed.
