Accumulating small-pitch LED display chips are widely favored by global display screen customers

Since the end of 2013, Accumulation Technology has introduced small-pitch LED display chips - MBI5151, MBI5152, and MBI5153, which are highly regarded by global display screen customers. Small-pitch LED display enters indoor applications, which is an unstoppable trend. Indoor advertising screens (shopping malls, shop windows, subways), multi-purpose conference halls, banquet halls, studios, central control rooms (traffic, military, map display rooms) ), even to the real LED TVs for home applications.

Small-pitch LED display applications are so widespread and promising, but there are still six major challenges that plague LED display manufacturers. These challenges include: ghosting, first line sweeping, low gray unevenness, low gray bias, Gradation dark lines and LED dead pixels cross phenomenon. Accumulate a series of small-pitch LED display chip products, completely solve the pain points of LED display manufacturers, and make the small-pitch LED display meet the critical eyes of the terminal customers; therefore, under the favor of the global display screen, the accumulation of Led Driver chips has always been high. The advantages of grayscale, high refresh and high reliability have also successfully made display manufacturers using MBI515X series chips win in various applications, and successively handed over beautiful sales transcripts.

In the conference environment application such as LCD splicing screen or DLP projection, the small-pitch LED display with the accumulation of exclusive MBI515X series chips perfectly complements the high-quality image quality, while the complete and delicate large-size screen experience, less the traditional LCD solution. The borders are bound, the business message is completely conveyed, and the noble and extraordinary atmosphere is added to make the guests feel honored!

In the application of TV studio, the small-pitch LED display is equipped with the MBI515X series, which accumulates high-refresh and high-gray scale. The camera can avoid the frequency interference phenomenon during shooting without the need to slow down the shutter speed, and complete the detailed broadcast picture.

The application of the central control room or the monitoring room is not interrupted in the case of multi-screen display, and can be arbitrarily cut into the size of the picture or the single picture. Therefore, the small-pitch LED display screen is combined with a high-reliability dedicated chip, which is in line with the high-reliability playback quality of this application, and the need for LCD display stitching or DLP projection to dim the ambient light source display image requirements.

In addition, in the application of rental screens, the diverse environment includes stage, event, conference or exhibition site, etc. The small-pitch LED display is matched with the high-gray, high-gray chip series, except for the splicing. The enhanced visual feast of fine lifting and delicate grayscale image processing enhances the opportunity to interact with the audience.

Figure 6 shows the FMEA exhibition site in the Middle East Dubai. The fine grayscale image processing of the small-pitch LED display successfully attracts the attention of the rental screen buyers and completes the order transaction.

After entering the indoor application, the small-pitch LED display brings the distance to the audience. Because of this, viewers and end customers have stricter requirements on the quality of LED displays. LED Driver chips play an important role in the performance of LED display screens. As a leading manufacturer, Accumulation Technology will continue to make breakthroughs and innovations, and work together with customers to develop high-quality small-pitch LED displays.

Accumulation Technology will demonstrate six challenges and solutions for small-pitch LED displays at ISE 2015. The booth number of Accumulation Technology is 8-H350, and invites you to experience it together. (This article is the accumulation of technology contribution)
