P2.5LED display, P3 and P4 to achieve ultra-high resolution, showing a breathtaking high-definition image effects; with high brightness, visual distance, to ensure that the stage or business area of the remote area can watch the display ;
Recently, many customers are asking full color LED display P2.5, P3 and P4 which is more clear effect better?
First, the value of P is the distance between the two pixels or the distance between the lamps (units are mm), so P2.5, P3, P4 point spacing are 2.5mm, 3mm, 4mm. The same area on the number of points, P2.5 to send more than P3, P3 than P4, for example, 1 square meters on the area of P2.5 pixels have 160,000 points, P3 pixels about 111111 points, while the P4 Only 62500 points, the smaller the pitch, the higher the pixel, the better the screen clarity. So P2.5, P3 than the P4 display more clearly.
Point spacing is smaller, the production will be a corresponding increase in difficulty, the unit square pixel increase, the cost increases, the price will be relatively improved, so P2.5, P3 is more expensive than P4, but here is not that P4 is not good, because the screen The larger the distance between the points on the body, the more suitable for the farther away the viewing distance, generally have a formula to best view the distance = point spacing / (0.3 ~ 0.8), which is a rough range. The formula is calculated P4LED display suitable for viewing distance of 5-13m, in this range to watch, the effect will be very good enough to meet the daily actual display. Of course, if the use of P2.5, P3LED display, the effect will be very good, but the cost will be higher than some.
P2.5 display, P3 full color display models: good clarity, the best viewing distance of 2-20 meters, the price is relatively high, the pixel / clarity / effect requirements are higher, you can use these two model.
P4 full color display model is currently on the market the most used models, can be regarded as commonly used LED large screen models, pixel density 62500 points / square meter, the best viewing distance of 4-20 meters, and the price relative to P2.5, P3 There is a great advantage, and now a lot of high-definition LED display is to use this model.
It is worth noting that: choose the right outdoor, indoor full color LED display must consider the distance and screen area, price and other comprehensive factors, it is recommended to choose to meet the daily display of the actual application on the line, the most appropriate is the best The
Full color LED display will not hurt the eyes?
High-density full-color LED display because of its unique high brightness, wide color gamut, high contrast and other advantages in many occasions by the people of all ages. At the same time, high-density LED display on the human eye light biosafety issues have also been people's attention.
China Institute of Metrology, based on the current international standards, from the retinal blue light hazards and thermal hazards in two aspects, a P1.66 high-density LED display light biosafety was measured, and selected the plasma TV and LCD TV prototype As a comparison.
The test results show that in the same brightness and white field conditions, in the blue band, although the peak brightness of the LED display is higher than the other two samples, but its narrow band characteristics make it weighted after the retraction of the retinal hazard index No more than plasma TV and LCD TV, three different display retinal photobiological safety measurement data no significant difference, three samples, LED display measurement results even better than the other two kinds of display.
It should be noted that any display long-term viewing of the human eye are likely to cause permanent damage, so no matter what form of full-color display, the operating staff should pay attention to eye health, develop good habits, Work and rest, consciously, take the initiative to protect the vision.
