The Pixel Sharing Engines Technology, through hardware and software innovation, sees the pixel pitch reduced by 50%, the resolution increased by 4 times, and a balance between the cost and resolution of the display product struck. As regards hardware, the hardware arrangement of the LED chip is changed from the traditional RGB arrangement to RGBG arrangement, by adding a green LED chip according to the theory of spatial color mixing and the visual characteristics of human eyes. On this basis, the combination of sub-pixel multiplexing technology and sub-pixel sampling technology, plus up, down, left and right subpixel multiplexing, produces four virtual pixels, theoretically increasing the resolution by a factor of four. As for software, a special optimization algorithm for super-COB matching RGBG arrangement is adopted to improve display product clarity, reduce color errors, and restore the original image.
Pixel Sharing Engines Technology allows the addition of a small number of LED chips to the structure of 2K products, theoretically realizing the effect of 4K products, with the result that both the amount of LED chips and the production cost of Micro LED display products greatly drop. Ledman’s pioneering breakthroughs in technology have been widely recognized by the industry. In June 2021, Ledman saw its Pixel Sharing Engines Technology win the “2021 ISLE Technology Achievement Award” for its innovation and advancement. Now, the Pixel Sharing Engines Technology has been widely used in a number of Ledman’s COB display products.
What measures has Ledman taken to protect Ledman Pixel Sharing Engines Technology?
In 2020, after several years of dedicated research, Ledman applied for patent protection and computer software copyright protection for the “Pixel Sharing Engines Technology“. And the same year saw Ledman obtain the patent certificate and computer software copyright registration certificate from the China National Intellectual Property Administration (CNIPA). In July 2020, Ledman held a press conference to release the “Ledman Micro LED Pixel Sharing Engines Technology”, announcing mass production of the 0.79mm and 0.63mm pitch Micro LED UHD displays, which are based on COB integrated encapsulation technology and uses Pixel Sharing Engines Technology.
Ledman has applied for Pixel Sharing Engines Technology patents in China and many overseas countries. Thanks to the intensive input in the R&D of LED display technology and extensive patent layout of LED products, Ledman has more than 460 granted and pending patents.
