A few days ago, JYLED sent a batch of P3.91 indoor small-pitch LED displays to India. Today, I will share with you some of the contents of this P3.91 indoor small-pitch LED display. Friends who want to know will come together.
When customers choose small-pitch LED display products, their primary concern is brightness. An important criterion for high-quality P3.91 indoor small-pitch LED displays is to achieve the "low brightness and high gray" technical indicators.
When choosing dot pitch, pay attention to the balance effect and technology: the outstanding feature of P3.91 indoor small pitch LED display is the smaller dot pitch. In practical applications, the smaller the dot pitch, the higher the pixel density, and the closer the distance suitable for viewing. On the contrary, the longer the distance suitable for viewing.
P3.91 Indoor small-pitch LED displays want to achieve better visual effects and have a better viewing distance. Users can perform simple calculations. There is an established formula, that is, better viewing distance = dot pitch/0.3~0.8 . The smaller the dot pitch, the higher the cost of the P3.91 indoor small-pitch LED display. Therefore, in actual purchase, users must comprehensively consider their own cost, demand, application range and other factors.
The P3.91 indoor LED display in India is used in the conference room. LED display screens are generally driven by constant current, and the driving methods are divided into static scanning and dynamic scanning. In simple terms, static scanning means that one pin of the driving chip controls an LED, and dynamic scanning means that one pin of the driving chip is refreshed. Control several LEDs to light up. The static scanning display effect is relatively good, the light loss is small, but the cost is relatively high; the dynamic scanning display effect is relatively poor, the light loss is relatively large, but the cost can be reduced.
Common dynamic scans are 1/2 scan, 1/4 scan, 1/8 scan and 1/16 scan. Outdoor LED display is an outdoor terminal that can be used for all-day display, so the requirements for screen brightness are stricter. Generally, when the screen is facing south and facing north, the screen brightness should not be lower than 4000cd/㎡; when the screen is facing south, the screen brightness should not be lower than 8000cd/㎡ to achieve better display effect.
If the budget allows, you can choose a product that automatically adjusts the screen brightness according to the outdoor natural light intensity. On the one hand, it can reduce power consumption and operating costs, and on the other hand, it can also reduce light pollution.
The application of high-brightness LED display in our lives can be said to be quite extensive, and it can indeed bring very good images and video rendering capabilities, and can still achieve good results in an outdoor environment under direct sunlight. When the led display is in use, it can achieve higher brightness, and it can be displayed outdoors all over the world, and the size can also be extended indefinitely. It can achieve the effect of infinite splicing, so it can increase the use of functions, and Good results can be achieved in a variety of environments. As long as it can be through normal maintenance and maintenance, the service life can reach more than ten years, and the high-brightness use effect can also be maintained, so it can make our use more functional, which can bring better display effects. It can present delicate effects in various environments.
JYLED, as one of the LED display companies with a relatively high number of local supply and sales in India, has developed into a local industry pioneer and a professional service technology entity. It is shortlisted with technology and based on service assurance.
Strict quality management and perfect service system will meet the needs of customers as a whole, and have won extensive trust and support from customers.
Each LED unit board performs single-module brightness adjustment, that is, white balance fine-tuning, to ensure uniform white balance between modules. Assemble the modules into a box. The box body adopts steel plate reinforcement structure, and strengthened ribs are added at appropriate positions. Ensure the rigidity and flatness of the box plane. The box body stamping and bending are formed by numerical control equipment at one time, and numerical control punching machine is used to ensure the accuracy of module installation. And there is a proper margin to eliminate the accumulated error.
The LED display screen is a high-tech product integrating optoelectronic technology, microelectronic technology, computer technology and video technology. Its light-emitting part is composed of LEDs (ie light emitting diodes). Its advantages are low power consumption and high brightness. , Low working voltage, simple drive, long life and stable performance. The area of the display screen can be assembled arbitrarily by the unit modules as required, and the response speed is fast. The emergence of LED displays makes up for the defects of the previous magnetic flaps, neon lights and other information release media effects.
With its varied colors, patterns, real-time dynamic display mode, good multimedia effects and strong visual impact, it displays information, text, pictures, animations and videos in a variety of ways, becoming an epoch-making product for information dissemination. It has been widely used in railways, civil aviation, stadiums, conference halls, highways, squares, large shopping malls, certificate and coupon markets, and a variety of monitoring and dispatching.
