For full-colour LED display, colour light-emitting point for a light-emitting unit, the core of 1R1G1B or 2R1G1B is a pixel.

We used to know P10mm, P8mm, this kind of large pixel pitch, but higher pixel density can improve visual quality, this does not mean that smaller pixel pitches are ideal in all cases.

Indoor rental led display often faces some external reasons for damage, so he must have a certain damage resistance,like P3.91 indoor stage rental screen, is required to withstand people stepping on it, so the quality requirements will be higher,because it is placed on the ground and moisture-proof.

3. P3.91 Indoor Rental LED Display Cautions

1. 91mm indoor rental led display has a lightweight and thin structure, so that the rental led display panel can easily load and unload, easy to operate. Even so, you need to be careful in the process of handling it.

2. The brightness of indoor rental led screens has a great impact, too high brightness is easy to damage our vision, and also harmful to our health. In general, the brightness of indoor rental led display to 800cd/㎡-2000cd/㎡ is appropriate.

3. Flatness. The flatness of the P3.91mm indoor rental led display will affect the quality of the picture or video you want to show to your audience. It depends on the manufacture of the led display, so our led display is after layers of gatekeepers, and have technical service support.

4. Viewable Angle. The size of the LED display viewing angle directly determines the size of the LED display audience.

5. Colour reproduction. LED display of colour reducibility refers to the display of the colour to maintain a high degree of consistency with the colour of the broadcast source, to ensure the authenticity of the image

6. Light source. In the performance, the stage and only LED rental screen a light source, the display effect is bound to be affected by projection moving headlights and another stage lighting. So high-end rental screen is necessary to install automatic adaptation of light-sensitive adjustment equipment, which will not affect the display screen due to ambient light.

7. Sound source requirements. In some rental screen applications of high-end occasions, such as museums, concerts, press conferences, etc. on the LED display noise requirements, the need for a low-noise fan or no fan and low-noise power supply, sometimes to achieve this effect, will put forward higher requirements for the power supply part.

8. Cabinet monitor. During the activity, the state of the box should be accurately monitored to avoid sudden accidents. Staff can connect to the controller on the PC side to monitor the indicators of the led display in real-time when it is running.

9. Power backup and Receiving card backup back-up, Because each activity is not possible only a box in the work, the whole indoor led rental display is composed of many parts, and electronic equipment more or less will have some electronic failure, so the backup power supply and backup dual card are very necessary, these two can ensure that the display in the event of failure can still work normally.

10. Lower Reflection, there are some activities site is not only led display the only light source, the existence of projection, spotlights and other light sources, so led display package device using black, can absorb all light sources, reduce the interference of light reflection, so that the overall picture is more soft and vivid and natural transition.

Second, the uncertainty of the event address and the temporary nature of the placement table construction.
Third, the brightness of natural is brighter than indoor, so the pixel pitch of outdoor rental led display is larger than indoor.

Many people who want to buy or rent led displays are most concerned about the price issue, here we will analyze the price of the rental screen.

2. Pixel pitch, we all know that the smaller the pixel pitch is, the price could be higher.

3. The difference between Outdoor and indoor. As far as I am concerned, outdoor rental led display is more expensive than indoors, because the outdoor one requires higher protection level, like waterproof,dust-proof and brightness, but the indoor one for these two is not so demanding.

4. Labour costs for after-sales and maintenance services. Including the free of charge during the two-year warranty period.

After knowing the requirements of rental led display price, then you may want to know how can you get the reasonable-cost rental led screen.
