On the 21st (local time), at the Nangang Exhibition Center in Taipei, Taiwan, the largest IT and computing exhibition in Asia, 'Computex 2025', showcased Samsung Display's 27-inch UHD Quantum Dot (QD)-Organic Light Emitting Diode (OLED) products displayed at private booths of Taiwanese corporations such as ASUS and MSI. At the entrance of the private booth, a robot from Rainbow Robotics was performing a 'robot show' by placing OLED and Liquid Crystal Display (LCD) panels into two cylinders and blowing air to demonstrate how much lighter the OLED is compared to the LCD.
The 27-inch UHD product ranks among the highest in sharpness within 27-inch monitor screens. The pixel density is above 160 pixels per inch (PPI), making it the highest among self-emissive gaming monitors. While resolution simply indicates the number of pixels that make up the display screen, pixel density refers to the actual density of pixels, regardless of the size of the screen.
The 27-inch 5K resolution product has a pixel density of 220 PPI, recognized for being optimized for professional tasks such as image and video editing. However, currently, only Liquid Crystal Display (LCD) products are available in the market. Samsung Display was the first to unveil a 27-inch 5K high resolution utilizing OLED technology.
According to market research firm Omdia, Samsung Display recorded shipments of approximately 150,000 units of 27-inch UHD QD-OLEDs in the first quarter, which accounts for 27% of the total OLED shipments for monitors in the first quarter.
A representative from Samsung Display noted, 'The 27-inch size accounts for the largest proportion of the monitor market' and added, 'With UHD high-resolution products being released at reasonable prices in this universal size, the demand from both general consumers and monitor manufacturers has been confirmed, and the company is expanding supply in response to this.'
Implementing UHD high resolution in a 27-inch self-emissive monitor is considered one of the examples of the 'technology barriers' established by Samsung Display. Although self-emissive panels with UHD resolution are produced in various sizes such as 32 inches and 34 inches, Samsung Display is the only company supplying UHD self-emissive panels in the more price-accessible 27-inch universal size.
The technological capability to implement high resolution in self-emissive displays is closely related to the front-emission structure of QD-OLED. Existing self-emissive displays had the problem of light being emitted towards the substrate, causing some of the light to be blocked and reducing the aperture ratio. However, since QD-OLED emits light in the opposite direction of the substrate, the part of the light being blocked is minimized, greatly increasing the aperture ratio. With a higher aperture ratio, the same brightness can be produced in much smaller pixel sizes, making it advantageous for implementing high resolution.
A representative from Samsung Display stated, 'For the transition from LCD to OLED technology to occur, we must not only demonstrate performance superiority but also be able to showcase solutions that consumers and clients have been waiting for at a reasonable price in a timely manner.' He further added, 'Samsung Display will continue to lead the self-emissive monitor market by introducing a product line that encompasses not only gaming but also movie viewing and work.'
