With the continuous advancement of LED technology, indoor LED display products are also constantly updated. From the early three-in-one to the later three-in-one, from the original large spacing to the current small spacing products, every product improvement is related to The progress of LED chip cutting and packaging is inseparable. LED advertising screens began to be widely used in indoor professional display scenes, and began to divide the display market with DLP rear projection technology and LCD splicing technology that dominate the professional display field. Powerful LED display manufacturers have developed new application models and application fields for high-density small-pitch electronic screens.
Where can small spacing LED displays be used?
After nearly five years of development, small-pitch LED displays have made huge improvements in the clarity of display panels. As density increases, further reduction in pixel pitch becomes progressively more difficult. The following is a brief analysis of the professional application scenarios of LED displays to help eliminate customer misunderstandings in the application of certain products.
Analysis of application fields of small spacing display screens
As a new generation of indoor professional display panels, small-pitch LEDs have the most direct impact on traditional DLP. From another perspective, small-pitch LED displays actually form a technical replacement for DLP in product applications. But this substitution is not a simple one-to-one. There are still great application differences between small-pitch LED displays and DLP, so the technical selection of screens is particularly important for different projects. The following is a brief analysis of the professional application scenarios of LED displays to help eliminate customer misunderstandings in the application of certain products.
Radio and television studio scene application
Video background applications in radio and television studios are most typical of anchor background video walls. The studio has very strict requirements on technical indicators such as color temperature, brightness, grayscale, viewing angle, contrast, refresh rate, etc. of the display panel. Before the emergence of LED high-definition display, more implementation solutions were rear projection splicing or LCD splicing. Traditional LED electronic screens are difficult to meet the needs of such places in terms of technical parameters and performance, and the emergence of small-pitch products has directly subverted the studio’s understanding of LED.
Small-pitch screens can easily meet the application of such scenarios in terms of various technical indicators, and because the LED advertising screen has no seams and small unit size, it can easily meet the inner-curved digital stage design, and it is even more advanced in terms of contrast, color, etc. It is better than other panels, so radio and television applications will be an important area for high-definition LED advertising screens.
Applications in the field of security monitoring
In the early days of small-pitch applications, in the design of solutions for the security field, especially small and medium-sized projects, everyone would feel helpless about the insufficient resolution of LED advertisements because there were a large number of security signals and a large number of signals on the screen. Under the condition of limited display area, the resolution is insufficient, especially in the context of digital high-definition signal sources. This hardware asymmetry is particularly obvious. Through the accumulation of experience in many projects and familiarity with the security business model, the hybrid model of LED + LCD has gradually been accepted by customers.
This model, under the condition that customers can display multiple signals on the screen, introduces LED as the main screen display, avoiding technical defects such as the patchwork of the LCD screen, and can respond well to security customers when calling for research and judgment signals for amplified close-ups. needs. Through flexible configuration solutions and the integration of different dot spacing and LCD and other display technologies, LED advertising screens have also entered the application field of security, and with the increase in dot density, there is an opportunity to directly abandon LCD in some projects. Adopt full-screen LED advertising screen mode. Of course, with the advancement of LED electronic screen technology, we will also see more new display areas being developed.
It is not difficult to find that small-pitch LED display products are gradually penetrating into the professional display field from traditional commercial display carriers. From the product itself to the back-end system, adjustments and improvements are being made all the time.
