How to make the LED display more HD

As society develops faster and faster, LED display screens can be seen everywhere. As the main carriers of advertising and information broadcasting, led display follows the trend of the times in contemporary era. High-definition video often gives people a more stunning visual experience, and the displayed content will be more realistic. How to make the LED display more HD?

To achieve high-definition display must have four factors, first the source requires full HD, the second is the display can support full HD, the third is to reduce the LED display pitch, the fourth is using LED display and video processor. Full-color LED displays are actually moving towards higher clarity.

First, improve the contrast of full-color LED display

Contrast is one of the key factors affecting the visual effect. In general, the higher the contrast, the clearer the image is and the brighter the color is. Contrast has more influence on the dynamic video display effect. Because the light and shade conversion in the dynamic image is faster, the higher the contrast, the easier the human eye can distinguish the conversion process.

In fact, the contrast improvement of full-color LED display screens is mainly to increase the brightness of full-color LED display screens and reduce the surface reflectivity of the screens. However, the brightness is not as high as possible. Too high will affect the LED display. The life of the screen can also cause light pollution. Light pollution has become a hot topic now. Excessive brightness will affect the environment and people. The LED panel and LED light-emitting tube undergo special processing to reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

Second, increase the gray level of full-color LED display

Gray scale refers to the brightness level of the single primary color brightness of a full-color LED display screen, which can be distinguished from the darkest to the brightest. The higher the gray level of a full-color LED display, the richer the color, the more colorful the color; display a single color, simple changes. The increase in gray level can greatly increase the color depth, so that the display level of the image color increases geometrically. LED gray scale control level is 14bit~16bit, which makes the high-level display product's image level resolution detail and display effect reach the world advanced level. With the development of hardware technology, LED gray scale will continue to develop higher control accuracy.

Third, reduce the full-color LED display pitch

Reducing the dot pitch of a full-color LED display can improve its sharpness. The smaller the dot pitch of a full-color LED display, the finer the screen display. However, this must be mature technology as the core support, the input cost is relatively large, the full color LED display produced into the price is also high, but fortunately the market is also moving towards a small pitch led display development.

Fourth, LED display and video processor combination

The LED video processor can use advanced algorithms to modify the signal with poor image quality and perform a series of processing such as deinterlacing, edge sharpening, motion compensation, etc., to enhance the details of the image and improve the picture quality.

The video processor image scaling algorithm is used to ensure that the video image is scaled to maintain the sharpness and gray level of the image as much as possible. In addition, the video processor is also required to have rich image adjustment options and adjustment effects to process the image brightness, contrast, and gray scale so as to ensure that the screen output is soft and clear.

Will small pitch led display develop better than traditional led display in the future?

It is well known that the small pitch LED display is generally an indoor LED display with pitch below 2mm. At present, the small pitch LED display is widely used in the security monitoring, command and control center, radio and television station, video theater and other high-end fields.

The mainstream small pitch LED displays in the market include P1.25, P1.5625, P1.667, P1.875, P1.923, P2 and so on. Compared with the conventional LED display, the pixel control technology of small pitch LED display is more advanced and reliable, and it can improve the brightness, reducibility and uniformity of the display screen. Therefore, the small pitch LED display has a higher use value, and the advantages are very obvious comparing to the traditional DLP backdrop display. Below TCB give you a summary analysis of the comparative advantages of small pitch LED displays comparing to traditional display devices.

1. The integrity of display pixel is higher: the current high-end market of the indoor display is still DLP projection display, but DLP technology has some natural defects. It can not eliminate the display unit between the seam. The jointing of each display unit will devour at least one display pixel, so the display pixel is not complete. For small pitch, there will be no such problem. Small pitch LED display can perfectly compensate for this defect, and ensure that each display unit has a complete display pixel.

2. The screen color performance is better: as the DLP projection display shows the differences between the unit, so color and brightness uniformity for the entire screen is difficult to control. Also as time goes by, there will be more and more obvious differences between the display units . However, the professional small pitch LED display uses pixel level point control technology. The color performance of each display unit has a high degree of unity, which can make the screen's color expression better.

Image played by the small pitch LED display screen is with high pixel integrity, rich picture expression, and exquisite color. It is difficult for traditional display devices to do this. Therefore, TCB believes that high-quality, reliable and small pitch LED displays have broader development prospects than traditional displays.

Why outdoor small pitch led display get more and more popular

Outdoor small pitch LED display eliminating the audience’s strangeness of LED display screen, make display information dissemination effect greatly improved. Outdoor SMD led screen is more convenient to achieve human-computer interaction, for better display advertising creativity and user experience.  People will also accept this kind of led product more easier . However,where is the stage field of small spacing LED display?

LED outdoor consumers are mainly traditional outdoor media and leasing business. The development of sports has prompted the LED stadium screen. In recent years, the education sector has also become a rising buyers of outdoor LED screen display, public schools are equipped with the large outdoor screens and some high-end retailers are willing to pay for playing brand advertising.

As we all known that the smaller the distance between pixels, the number of led lights used in one square is more, the entire screen cost is higher and now, the price has become a major problem plagued the popularization and application of LED outdoor small spacing display. Therefore, the development of large size is not necessarily mainstream, after outdoor LED small spacing screen showing up, it will display very perfect in some small square places.

First, outdoor digital signage advertising machine market demand structure changes in size, large size is more popular. The complex outdoor environment on display has put forward higher requirements to the original terminal.  "Bright", "High Protection", "Tolerance" is the first premise. In this aspect, LED has the absolute advantage alternative to the traditional LCD digital signage.

Second, in recent years, a large number of domestic and foreign well-known brands and luxury goods settled in city commercial street. Using LED play brand information is more and more popular, small spacing LED screen is perfect for close viewing, which is very suitable for installation in the window or the street.

 

Third, with the development of smart city construction work started, smart bus stations and wisdom community are gradual implementation. The outdoor small spacing LED will undoubtedly make intelligent bus stop, kiosks more dynamic. It can be understood that using intelligent control system and advanced information technology connected with the powerful database to present report useful information in real time and to bring convenience for passengers, residents.

Outdoor small spacing LED screen started to small and medium size places. On the basis of not capturing the market of the original outdoor display, but based on  the expansion of new areas in the traditional market. The launch of a small pitch LED display not only make up the short board for the traditional LED display on display effect, but also combine with the touch, EVO 3D, cloud computing and other trend factors.

We should not only put the LED display locate at static advertising carrier field, we should think about how to achieve a good interaction between the audience and the display to maximize advertising effectiveness and output. It will indirectly enhance the LED display value, broaden the application field of small pitch LED display.
