Qipu Optoelectronics introduced a hollow screen, similar to the grille screen, but with a light barrier behind it, opaque. Since the middle of the screen is empty, it is called a hollow screen. Qipu photoelectric hollow screen not only solves the problem of temperature rise of the display screen, but also solves the problem of contrast and sharpness. 
The above picture shows Qipu Optoelectronics outdoor advertising LED hollow screen Qipu Optoelectronics () hollow screen has obtained the national invention patent, patent number is 201110350023.1, the current hollow screen models include AV10, AV13, AV16, AV26 and so on.
The technical advantages of the hollow screen:
Can be ventilated - the airflow can directly penetrate the screen, the ventilation rate is up to 50%.
It is opaque--transparent design but opaque, no loss of contrast, and the display effect is not compromised.
Low wind resistance - steel structure reduces wind requirements and saves structural costs by 35%.
Air-free------------------------------------------------
Energy saving and environmental protection - less energy consumption, energy saving 50%.
Adaptable - the protection level reaches IP65, fully sealed design, rain and dustproof, suitable for all-weather working environment.
Hollow screen application areas:
Applicable to outdoor advertising media, government and enterprise engineering, cultural tourism, sports competitions, image publicity, commercial real estate, etc.
Data analysis and energy saving of the hollow screen:
Take the outdoor P16 full color 320 square screen as an example to calculate the running cost:
1, regular full color screen: daily cost (8 am to 11 pm, a total of 15 hours)
350 (W) * 320 (square) * 15 + 4500 (W) * 11 * 15 = 1680000 + 742500 = 2422.5 (KW)
According to the calculation of 0.8 yuan per kWh, the electricity bill is 1938 yuan per day.
2, hollow full color screen: daily cost (8 am to 11 pm, a total of 15 hours)
350(W)*320(square)*15 = 1680(KW)
According to the calculation of 0.8 yuan per kWh, the electricity cost per day is 1344 yuan.
3, hollow full color screen than conventional full color screen daily energy saving cost 1938-1344 = 594 yuan 4, annual energy saving cost 365 days * 594 yuan = 216,810 yuan Note: 350 (W) refers to the average power consumption of the display, 320 (square) refers to the display Screen area, 15 refers to daily working hours, 4500 (W) refers to the power consumption of 3P air conditioner, and 11 refers to the number of air conditioners required for the display.

The hollow screen is an air-free, air-permeable and opaque outdoor LED outdoor advertising screen pioneered by Qipu Optoelectronics. The conventional outdoor LED advertising screen is a sealed box with a high working temperature and requires air conditioning to ensure normal operation. Two or three years ago, there was a grill screen that did not require air conditioning. The air was transmitted through the air and naturally dissipated. No air conditioning was needed, but the contrast and sharpness decreased after the light transmission, and the playback effect was not satisfactory.
