The best resolution for an LED screen depends on the viewing distance. For close viewing (within 3 meters), a P1.2 or P1.5 screen with 694,444 pixels per square meter offers sharp details. For medium distances (5-10 meters), a P2 or P3 screen with 111,111 to 250,000 pixels per square meter works best. At longer distances, a P6 to P10 screen is optimal.
Small Screens
Ad screens are usually established at areas with large flows, such as business quarters, bus stations, or park entrances. The common distance to see such scenes is 2-5 meters. A P2 screen has a pixel density of about 250,000 pixels per square meter, while for P3, it is 111,111 pixels. It means that a P2 screen provides high-quality images within 3 meters, while for P3, the same quality can be achieved when watching from about 5 meters. Manufacturing cost of P2 screens is generally around 40% higher when compared to the manufacturing cost of P3 screens.
As an example, at an average viewing distance between the audience and the screen in the range of 1.5 meters up to 3 meters, the pixel density for a P1.2 screen can reach a value as high as 694,444 pixels per square meter. The selling price of P1.2 is about 25,000 RMB/square meter; in high-end scenes, however, the rate of advertising transformation could be lifted up by about 15 to 20 percent. A P3 screen may be about 12,000 RMB/square meter or around 30% cheaper compared with P2 screen pricing. It can consume about 20% less power than a P2 screen.
For outdoor screens, the brightness should be at least 5000 nits, while for a shaded area or operation at night, 4000 nits will do. Power consumption of a P2 screen in high-brightness mode is 400 watts per square meter, with a lamp life of about 50,000 hours. By reducing the brightness to standard mode, power consumption can be reduced by 15%, and the life can be elongated to 60,000 hours.
The refresh frequency for the LEDs should at least be 1920Hz according to industry requirements, while normally high-end screens can reach around 3840Hz. Moreover, screens with a refresh frequency over 3000Hz improved the recall ratio of advertising contents by about 18%. Consumption While one 10 sq.mtr. P2 consumes around 4 KWH Power/HR., A P3 screen consumes about 3.2 KWH. Especially for advertising screens that need to operate 24 hours a day, the annual operating cost of a P3 screen is about 15% lower than that of a P2 screen.
The working time for indoor small screens usually is 80,000 hours under constant temperature and low humidity, while the outdoor ones will be affected by humidity, temperature difference, and dust, thus reducing the working time to about 60,000 hours. To prolong the life time of the screen, many manufacturers control the screen temperature below 50°C.
For example, one single LED lamp for P1.5 is 0.2 RMB, twice as much as that of a P3 screen lamp. If the screen area is large and the lamp failure rate is 1%, the cost of maintenance will be about 300 RMB per square meter for a P1.5 screen, while for a P3 screen, it will be only 150 RMB. Some high-end P1.8 screens combine AI algorithms to reduce overall operating costs by about 10% in total.
Medium Screens
Medium-sized screens are usually installed on building facades or beside highways, with the viewing distance between 10 to 30 meters. A pixel pitch in this case may fall between P5 and P10. For example, the P8 screen can reach 15,625 pixels per square meter, viewed at more than 25 meters, and a P5 screen can reach 40,000 pixels per square meter, which is clearly viewed within 15 meters. A P5 screen is about 18,000 RMB to produce per square meter.
For indoor scenes, the viewing distance is about 5-15 meters. Take P3 for example, whose pixel density reaches 111,111 pixels per square meter. A P3 screen costs about 20,000 RMB per square meter. Exhibitions using P3 screens can extend the average stay of audience by 12% more.
Average web consumption of the P5 screen is 400 watts per square meter, and the power consumption of the P8 screen is 320 watts. If it operates for 10 hours every day, an average 50-square-meter screen will cost around 6,000 RMB per month when using a P5 screen and 4,800 RMB per month using a P8 screen.
While outdoor screens are supposed to be 5000 to 7000 nits, indoor screens are normally just 800 to 1500 nits. For a P5 screen operating in high brightness mode, the lifespan will last for about 50,000 hours, which for normal brightness mode, will be extended up to 60,000 hours.
For example, a P3 screen contains 111,111 pixels per square meter; each lamp is valued at 0.2 RMB. If the failure rate of screen is 2%, the cost for maintenance could be around 444 RMB per square meter. For an P8 screen, with just 15,625 pixels on each square meter, the amount for maintenance stands at 62.5 RMB per square meter under the same failure rate. According to the industry chain, the general refreshing rate reaches no less than 1920Hz for middle-sized screens. For high-ranking screens, as expected, normally reaches 3840Hz. The display with a refresh rate over 3000 Hz reduces motion blur by 35% in high-speed dynamic videos.
For average screen life expectancy, IP65 protection-rated displays boast a higher than 20% longer time of service when compared to that without the protection grade. Within high humidity conditions, screens with no waterproof technologies are at higher risks of increasing failure rates up to 5% annually; those with a protection rating IP65 have failures recorded at meager 2%. A P5 screen audience can recall for HD ads up to 22% more than a P5. P4 smart screens shall assist in lowering around 15% of the general amount.
Large Screens
Outdoor large screens are usually installed at heights of over 10 meters, with a typical viewing distance of 30 to 100 meters. A pixel pitch between P10 and P16 is recommended. For example, a P10 screen contains 10,000 pixels per square meter, providing sufficient clarity at a distance of 50 meters, while a P16 screen has a pixel density of 3,906 pixels per square meter, suitable for viewing distances above 100 meters.
Outdoor large screens usually have a brightness of 5000 to 8000 nits. A 200-square-meter P12 screen consumes about 100 kWh per hour at a brightness of 8000 nits. Reducing the brightness to 6000 nits can reduce power consumption by 20%.
Indoor large screens typically have a viewing distance between 10 and 30 meters. A P6 screen has a pixel density of 27,778 pixels per square meter, providing high-quality images within 20 meters. Although P4 screens have a higher resolution, with a pixel density of 62,500 pixels per square meter, the cost per square meter of a P10 screen is about 8,000 RMB, while a P8 screen costs around 12,000 RMB. For a 300-square-meter screen, choosing P8 over P10 increases the total cost by about 1.2 million RMB.
A P4 screen contains four times as many lamps as a P8 screen. If the lamp failure rate is 1%, the lamp replacement cost for a P4 screen is about 250 RMB per square meter, while for a P8 screen, it is only 62.5 RMB. The refresh rate of large screens must exceed 1920Hz. The Screens with a refresh rate of 3000Hz improve audience satisfaction in dynamic video ads by 15%.
Screens with an IP65 protection rating have a 30% lower failure rate than those without the rating. Screens with active cooling systems can keep the operating temperature below 50°C. Under good maintenance conditions, a 200-square-meter large screen can last up to 80,000 hours.
A 500-square-meter P10 screen consumes about 250 kWh per hour in standard brightness mode. Using a P8 screen under the same conditions will increase the power consumption by 30%. Smart dimming technology can reduce total electricity costs by 15% to 20%.
Pixel Pitch and Display Precision
Large outdoor advertising screens are usually installed at heights ranging from 15 to 50 meters from the ground. The recommended viewing distance would be from 30 to 100 meters. A display device pixel pitch should be in a range between P10 and P20. A P16 screen contains 3,906 pixels per square meter and can ensure clarity in content visibility for 60-100 meters away.
View distances for indoor advertising are usually 5 to 30 meters. Pixel pitches ranging from P2.5 and P6 would be appropriate. A P4 screen has a density of 62,500 pixels per square meter. On the other hand, compared with a P6 screen, it costs about 30% more to manufacture and consumes 20% more in power.
According to the requirement for very big screens, which is larger than 200 square meters, the price of a P10 screen is about 8,000 RMB per square meter, and a P6 screen is about 12,000 RMB per square meter. Changing the material from P6 to P10 for a 300-square-meter screen saves roughly 1.2 million RMB in total.
In outdoor environments with direct sunlight, the screen brightness must reach at least 5000 nits. A 200-square-meter P10 screen consumes about 120 kWh per hour in high-brightness mode. Reducing the brightness to 4000 nits can reduce power consumption by about 15%.
In addition, industry thresholds require that refresh rates on large screens be higher than 1920Hz; high-end screens achieve refresh rates of over 3840Hz. Screens whose refresh rate is over 3000Hz result in an increase in visual comfort in dynamic video ads by up to 18%.
Since the number of lamps in a P4 screen is four times greater than in the P8 one, in this case, for example, for a P4 screen, this would amount to approximately 500 RMB maintenance cost per square meter, which for a P8 screen it would be about 125 RMB. So, if taken in average: P2.5 screen provides up to 50,000 hours of use, whereas in similar conditions, the P10 screen can boast more than 60,000 hours.
The average power consumption of a P6 display screen is 350 watts per square meter, while the most energy-efficient P10 display screens can only use up to 250 watts. A 500-square-meter P10 screen will consume roughly 37,500 RMB in electricity costs per month if it runs 10 hours per day, while a similarly sized P6 display would have a power cost of approximately 52,500 RMB per month. A certain brand’s smart P8 screen can cut its power consumption by 15% without degrading the viewing experience.
Outdoor Applications
Outdoor screens are normally erected at a position 10-50 meters above the ground with a viewing distance of 30-100 meters. P8 to P16 pixel pitches are the mainstream choice. The P10 screen owns 10,000 pixels per square meter, fitting the display distance of 50 meters or so. While a P16 screen has a pixel density of only 3,906 pixels per square meter but covered the wider range of view.
Outdoor screens need 5000 to 7000 nits of brightness. A 200-square-meter P10 screen at 6000 nits would consume about 80 kWh per hour, while the same screen operating at 4000 nits would consume about 65 kWh.
While non-compliant screens may fail at rates over 10%, an IP65-rated protection screen has a failure rate of less than 3% in a high-humidity environment. The lamp temperature can be maintained below 50°C with the help of an active cooling system in screens.
The sizes of common outdoors range from 100 to 500 square meters. A P8 screen costs about 12,000 RMB per square meter, while a P16 screen costs only about 8,000 RMB. For a 300-square-meter screen, choosing P8 instead of P16 will increase the total cost by 1.2 million RMB.
According to the industry standard, the refresh rate for outdoor screens should at least be 1920Hz, while high-end ones usually reach 3840Hz and above. Screens with a refresh rate of 3000Hz increase the dwell time of audiences by 15% in dynamic video presentations. In playing high-definition contents, a P8 screen has a clarity rating 20% higher compared to P10.
The P8 screen is about 350 watts per square meter, while the P16 is about 250 watts. A 500-square-meter P8 screen works every day for 12 hours, which costs about 630,000 RMB per month. But the P16 screen will cost about 450,000 RMB under such conditions.
With P10, there are 10,000 lamps per square meter, and replacing each lamp costs 0.2 RMB. So, assuming a 2% failure rate of the lamps, for a 300-square-meter screen, the cost would amount to about 6,000 RMB. For P16 under the same conditions, the maintenance cost is only 2,340 RMB.
Display Effect and Image Quality
Large screens have a typical viewing distance of 30 to 100 meters. A pixel pitch between P10 and P20 is recommended. A P16 screen has a pixel density of 3,906 pixels per square meter, providing good image quality at distances over 60 meters. A P10 screen has a pixel density of 10,000 pixels per square meter, offering clear displays within 50 meters.
Indoor applications typically have a viewing distance between 5 and 30 meters. A P4 screen has a pixel density of 62,500 pixels per square meter, while a P2.5 screen reaches 160,000 pixels per square meter. Exhibits using P2.5 screens extend the average audience’s stay by 20%.
Outdoor screens usually require a brightness of 5000 to 7000 nits and a contrast ratio of no less than 4000:1. A screen with 6000 nits brightness and a 5000:1 contrast ratio improves clarity in direct sunlight by 15% compared to screens with a contrast ratio of 3000:1. Indoor screens usually have a brightness of 800 to 1500 nits.
Industry standards require a refresh rate of no less than 1920Hz, and high-end screens can reach 3840Hz or higher. Refresh rates over 3000Hz increase viewing comfort by 18% in dynamic ads. Screens with an NTSC color gamut of 90% have 25% more color saturation than regular screens.
A 4K resolution P1.5 screen can present extreme detail within 10 meters, while the same-sized P10 screen only shows 1080p quality. The price of a P1.5 screen exceeds 25,000 RMB per square meter, while the price of a P10 screen is only about 8,000 RMB. In heavy rain conditions, IP65 screens maintain 98% of their image quality, while regular screens only retain 85%.
A P4 screen has an average power consumption of 350 watts per square meter, while a P10 screen consumes 250 watts. A 500-square-meter P4 screen running 10 hours a day will cost about 520,000 RMB in electricity per month, while a P10 screen under the same conditions costs about 370,000 RMB. Dynamic adjustment technology reduces energy consumption by 15% and improves image quality by 10%.
