A Samsung Display executive said Friday that compared with OLED display panels, MicroLED panels will be more suitable for use in augmented reality (AR) devices. This is because AR devices require high brightness, which will require the development of new light-emitting diodes, which OLED cannot achieve, according to reports, Samsung Display Group leader Kim Min-woo told a MicroLED Display Symposium in Seoul. Compared to LEDs, OLEDs have traditionally had lower brightness levels.
Sources previously revealed that Samsung is developing OLEDoS (OLED on silicon) and LEDoS (LED on silicon) display panels, and its long-term goal is to develop LEDoS with a resolution of 6,600 pixels per inch. OLEDoS (OLED on silicon) and LEDoS (LED on silicon) are display technologies that combine semiconductors with OLEDs or LEDs. Displays manufactured using these technologies can achieve ultra-high resolution in tiny sizes. It has the advantages of high brightness, high contrast, high PPI, fast response speed, and low power consumption, and is suitable for AR/VR devices.
During the event, Kim also said that AR, virtual reality, and mixed reality all have different specific needs. AR needs more brightness than VR because it interacts with the real world. This also means that it needs to be lighter, with a relatively small panel.
The AR display needs to be at least 5,000ppi, Kim said, with a pixel pitch of 5 microns or less, and red, green, and blue subpixels of 3 microns or less. He also said that LED chips must also be 10 microns or smaller.
According to the data, Micro LED display technology refers to a display technology that uses self-luminous micron-scale LEDs as light-emitting pixel units and assembles them on a drive panel to form a high-density LED array. Due to the small size, high integration, and self-illumination of micro LED chips, compared with LCD and OLED in terms of display, it has greater brightness, resolution, contrast, energy consumption, service life, response speed and thermal stability. The advantages.
