Recently, Hisense Business display, a B2B section of Hisense, officially launched a new generation of star map series COB products. It is reported that the new product uses a leading industry-level small-size flip COB chip, and is equipped with Hisense's self-developed film hunting platform to achieve radio and television reference quality, and achieve new breakthroughs in energy saving, low consumption and efficient maintenance, becoming another masterpiece of Hisense LED products.

As the mainstream technology of super large screen display in the future, LED represents the development direction of the display industry in the future. With the continuous development of LED display products to higher pixel density and smaller pixel spacing, COB technology has become the main development direction of micro-spacing LED display. According to industry research data, the COB display accounts for about 8.52% of the entire small spacing LED display in 2022. With the gradual development of micro-distance display technology and the reduction of cost, COB shows that the market segment will continue to grow by more than 30% in the next few years. Because of this, the major manufacturers have increased COB product development and innovation to seize the market.

The new generation of Hisense small spacing LED display COB star map series, its LED light-emitting chip size is only 70 μ m, smaller than the current industry level of 75 μ m, extremely small light-emitting pixel area, greatly improve the contrast, bring more immersive display effect. The product is also equipped with Hisense self-developed composite nano-coating technology, so that the light transmittance reaches 60%, and the reflectivity is less than 3.5%, which is better than the industry 40%, 50% transmittance and 5.2% reflectivity, further improving the contrast of the product, making the perceptual contrast of the star map COB series up to 40000. At the same time, the new generation of Hisense COB star map series products are more accurate in color reduction, meet the studio A standard, in the studio, exhibition and other scenes, can truly restore the display details, the picture effect is more vivid, bringing the ultimate display effect.

It is worth mentioning that Hisense small spacing LED display COB star map series is equipped with Hisense self-developed shadow hunting platform, which is a newly upgraded LED display technology platform based on the accumulation of Hisense display image quality technology for more than 50 years. The Hunting platform pursues the integration and innovation of products, environment and solutions, and focuses on miniaturized, high-efficiency LED chips, highly integrated, high-bandwidth, low-EMI ASIC control chips, and self-developed high-quality chips, with the leading picture quality experience as the core to create LED industry reference-level image products and solutions.

At present, the LED industry generally believes that the high screen refresh rate is 3840Hz, but the continuous emergence of new scenes such as XR virtual shooting puts forward higher requirements for the large screen display. The refresh rate is insufficient, and it is easy to appear scanning lines and water ripples when shooting with professional cameras. Hisense COB star map series, the refresh rate is as high as 7680Hz, solve the camera scan pattern phenomenon from the source, meet the XR virtual broadcast without scan pattern requirements, and the motion picture does not shake, it is more comfortable to watch for a long time. Through chip-level multi-angle optical simulation and DBR material and microstructure design optimization, the viewing angle of the large screen is greatly improved to 170 °, which can meet the needs of side seats on the ultra-long screen and seats on the second and third floors in the command center and other scenes.

In terms of energy saving, Hisense COB star map series products adopt the industry's only full-link energy-saving design to achieve maximum power consumption under 600nits, 188w/ "ultra-low power consumption, better than industry-level 300w/", screen temperature below 37 ℃, experience comfort near the screen, energy saving and low consumption. Taking 100ping as an example, it can save about 3 million kilowatt-hours of electricity a year.

Under the blessing of Hisense ASIC control chip, Hisense COB star map series still adheres to the design of the previous generation of COB products without sending card and receiving card, the link is concise, stable and reliable. Because the two-way data transmission can be realized between the lamp board and the box, the intelligent detection of the lamp board data provides greater convenience for maintenance, and the automatic correction can be realized after the lamp board is replaced, without professional equipment, and the correction efficiency is greatly improved.

Continuously strengthen the layout of LED product technology and industrial chain, enable the scene change of LED industry, is the goal of Hisense commercial display. In the future, Hisense Commercial Show will continue to give full play to the advantages of the in-depth layout of the industrial chain, continue to innovate product research and development, and create new changes in scene experience.
