Samsung announced that it will launch its full range of events starting this month 31Mass production work of a 5-inch UHD (3840 x 2160) resolution QD-OLED screen. 
According to Samsung, it uses advanced ultra-precision inkjet printing technology to apply to the QD (quantum dot) light-emitting layer, and successfully creates a 140PPI high-density ultra-high-definition (UHD) display product by optimizing the inkjet nozzle and jet nozzle, achieving "the highest level of pixel density and UHD resolution in self-luminous displays", which is equivalent to the pixel density of 65-inch 8K TVs currently on the market.
Because the distance of the display is closer than that of the general TV, the user's sensitivity to picture quality will be higher, and at this stage on the market, the OLED screen within 30 inches is generally QHD (2560 x 1440) resolution, and some consumers who like games and high-definition video content have a soft spot for UHD products, and believe that the **QD-OLED screen can meet their needs.
In addition, Samsung also plans to bring the industry's highest 360Hz refresh rate next year with a 27-inch QHD (2560 x 1440) resolution QD-OLED display, which is much higher than the existing 240Hz counterpart. With its unique AI-based driving algorithm "Quantum Enhancer", Samsung has achieved a revolutionary increase in refresh rate while controlling the response time at 003ms, bringing an extraordinary gaming experience to FPS players.
Samsung said that it plans to pass the 27-inch, 31With a variety of product lines such as 5-inch, 34-inch and 49-inch, we will develop new customers and actively expand the high-end display market, aiming to expand the shipment of QD-OLED screens to more than double the same period last year.
