LEDinside: LED Digital Display Trend in Cinema and Home Theater Market
Samsung officially released 34-foot Cinema Screen in 2017, and the screen has been installed at Lotte Cinema World Tower in Korea. This is the world’s first LED digital display that enters movie theaters. Samsung’s goal is to raise its share to 10% in the cinema display market in 2020.
Samsung LED Cinema Screen features a fine pitch of 2.5mm. It is not a Micro LED display; however, the LED technology is able to provide HDR imaging. Its peak brightness (146fL) is nearly ten times higher than that of a regular movie projector (14fL). It has improved the uniformity of LEDs and reduced effects of distortion and interruption. In addition, it provides a 4K resolution (4,096 x 2,160) image quality. The overall specifications meet and even surpass the requirements of Development Cooperation Instrument (DCI).
According to LEDinside’s analysis, the cinema market most emphasizes high refresh rate and high resolution. The average frame rate is about 24 fps. Fine pitch display can solve the problem that the image is presented in low refresh rate, and it can greatly improve the audio-visual enjoyment to even reach a 3D-like effect. In future, the naked-eye 3D technology is likely to bring more business opportunities to the display.
However, LED digital display may encounter problems such as poor heat dissipation, high power consumption and dead pixels. In response to cinemas’ demand for real-time maintenance and replacement, the display must feature the front plug-and-play technology.
On the other hand, Sony’s Crystal Micro LED display received a lot of market attention. It has several edges- wide viewing angle, high contrast, better image quality, and is able to integrate seamlessly with other identical modules, especially needed at locations such as showrooms, museums, and cinemas. LEDinside’s research points out that traditional display and LCD makers have prioritized the development of Micro LED displays and have planned to enter Micro LED display market by cooperation and alliance. It is believed that Micro LED display will enter the high-end niche market in the next three years when advanced technology becomes mature.
