What is small pixel pitch led display？
- The LED display is made up of LED lamp beads. The pitch of the LED display refers to the distance between the center points of the two LED lamp beads. The LED display industry generally uses this distance to define product specifications. According to the general consensus of the industry, LED displays with a dot pitch of less than 3mm are small-pitch LED displays.
- The characteristic of small-pitch LEDs is that the dot pitch of the screen is small, and the resolution per unit area is high. It can display higher-definition graphics images and videos, as well as more channels of videos and images. Especially in the application of image splicing, which can achieve seamless and arbitrarily large-area splicing.
- The small-pitch LED display can achieve higher resolution quality for displaying information under the same size. It also has many features such as higher refresh, low power consumption, etc., which is more in line with the actual effect requirements of standard modern advertisers users for LED display screens.

What is the advantage of the LED small pitch display?
- Seamless splicing:
The splicing large-screen display technology can not avoid the influence of the physical frame when it meets the needs of customers to the maximum. And the advantages of seamless splicing of high-density and small-pitch LEDs can be highlighted.
- Intelligent adjustable high brightness:
The led screen itself has high brightness, in order to meet the comfortable viewing effect for the viewer in the strong light environment and the dark light environment. And to avoid visual fatigue, the brightness can be adjusted with the light sensing system.
- High gray level and better color performance:
Even at low brightness, the grayscale performance of the display is almost perfect, and the image level and vividness of the display is higher than that of the traditional display screen, and also it can show more image details without loss of information.
- High contrast, faster response speed and high refresh frequency:
The times that the electron beam repeatedly scans the image on the screen. The higher the number of scans, the higher the refresh rate, and the better the stability of the displayed image. The lower the refresh rate, the more flickering and shaking the image, and the faster the eyestrain.
Under high refresh rate, the small-pitch LED screen can capture images stably, without ripples and black screens, with clear image edges, and accurately restore the true image information.
- Naturalization of color restoration
Adopting internationally leading point-by-point correction technology, using the principle of LED light emission, to completely retain the authenticity of colors. Avoiding color loss and deviation caused by other display technologies such as backlight projection materials and light running paths to achieve true color reproduction .
- Three-dimensional visual experience
When the customer chooses to use the 3D playback mode, the splicing wall will present shocking high-definition images, whether live TV, exhibition display, or digital advertising, can fully interpret the wonderful vision, allowing the audience to enjoy an extraordinary visual experience.

What is application of the Small Pixel Pitch LED Display?
- Exhibition:
The small-pitch LED screen has flexible structure, wide viewing angle, ultra-thin body, convenient and quick installation and maintenance, and low power consumption. It is widely used in various public information display fields.
e.g.: information bulletin boards in hotel lobbies, airports, cinemas, hospitals, etc., as well as corporate image promotion, museum cultural relics display, sports stadium scoreboards, etc.
- Security Monitoring:
With features such as seamless joints, good color performance, and low energy consumption, small-pitch LED screens can meet the needs of high-end indoor applications such as dispatching command centers, command and control centers, studios, and meteorological information centers that require higher picture quality.
- Business education:
Small-pitch LED screens can also meet the needs of various commercial fields, such as corporate conference rooms, chairman’s office, and network video conferences. It can replace the projector to create a bright office environment.
- Household field:
As a home, the outstanding advantage of LED TV is the use of independent light-emitting technology, brightness, color, and refresh rate are all superior to LCD TVs. Installation and maintenance are more convenient than projectors. Also it can display normally even in a bright audio-visual room.

What is the weakness of the LED screen pixel pitch?
- Cost:
The purchase cost of small pitch itself is higher than that of LCD, and the heat dissipation cost and electricity cost of LED display are also higher than that of LCD and DLP. The superposition of the two aspects makes the overall cost of use remain high.
- Stability:
For traditional LED displays, the dead-light rate is generally controlled below 1/10,000. But for high density small-pitch screens, the probability of 1 in 10,000 obviously cannot meet the picture requirements. A lower dead light rate has become an inevitable requirement, and more applications of small pitches in high-end fields have imposed stricter quality requirements.

What do you need to concern when you purchase a small pixel pitch Dispaly?
- The size and resolution of the dot pitch:
The size and resolution of the dot pitch are the most important factors when people buy. In actual operation, the smaller the dot pitch, the higher the resolution, and the better application effect. The smaller the dot pitch of LED scree pixel pitch products, the higher the resolution and the price.
- Viewing effect:
Indoor display screens usually control the brightness in the range of 100 cd/㎡—500 cd/㎡ to avoid uncomfortable viewing for a long time, but with the decrease of brightness, the gray scale of the LED screen will also be lost. The effect will be affected to a certain extent.
- Maintenance cost:
When users choose LED indoor HD display, not only the purchase cost, but also the high maintenance cost must be considered.
In actual operation, the larger the screen size, the more complicated maintenance process, and the maintenance cost will naturally increase accordingly.
In addition, the power consumption of a small pitch is not easy to become smaller, and the operating cost of a large-size LED small pitch display is usually higher.
- LED wall pixel pitch signal transmission compatibility is very important:
The indoor signal access of the led small-pitch display has the requirements of diversification, large number, scattered location, multi-signal display on the same screen, and centralized management. In actual operation, if the display screen is to be used efficiently, the signal transmission equipment must not be underestimated.
In the display market, not all small pixel-led display can meet the above requirements. When purchasing products, do not pay attention to the resolution of the product one-sidedly, and fully consider whether the existing signal equipment supports the corresponding video signal and after-sales service.

What we need to know about the installation of the indoor HD led display?
- Load-bearing requirements:
The LED small pitch screen has a great advantage in weight compared to the outdoor one, but if the area is relatively large, the weight of the entire screen is still very heavy. Therefore, the load bearing at the installation position must be structurally firm.
- Power socket requirements:
When the user installs the socket, it should be a special fixed socket with a ground wire and should be close to the place where the power plug is included with the equipment. The socket structure should match the power plug of the equipment to be installed and meet the requirements of GB1002.
- Ventilation and heat dissipation:
Install ventilation equipment to cool down so that the internal temperature of the screen is between -10°C and 40°C. Keep vents behind the screen as much as possible so that part of the heat produced by the transparent screen can be quickly dissipated.
- Waterproof protection:
The equipment and the connecting part of the equipment and the building must be strictly waterproof. The equipment has good drainage measures and can be discharged smoothly in case of accumulation of water.
