According to TheElec report on October 17, a Samsung Display executive said on Friday that Micro LED panels will be more suitable for use in augmented reality (AR) devices than OLED display panels.
Samsung Display Group leader Kim Min-woo reportedly said at the MicroLED Display Seminar in Seoul that this is because AR devices require high brightness, which will require the development of new light-emitting diodes, which OLED cannot achieve. OLEDs have traditionally had lower brightness levels compared to LEDs.
Sources have 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. It is understood that OLEDoS (OLED on silicon) and LEDoS (LED on silicon) are a display technology that combines semiconductors with OLED or LED. Displays manufactured using these technologies can achieve ultra-high resolution in tiny sizes and have the advantages of high brightness, high contrast, high PPI, fast response speed and low power consumption, and are suitable for AR/VR devices.
In this event Kim It is also said that AR, virtual reality and mixed reality all have different specific needs. AR requires more brightness than VR because it interacts with the real world. This also means it needs to be lighter and the panels relatively smaller.
Kim said the AR display needs to be at least 5,000ppi, the pixel pitch must be 5 microns or less, and the red, green and blue sub-pixels must be 3 microns or less. He also said the LED chips must also be 10 microns or less.
According to data, Micro LED display technology refers to the use of self-luminous micron-level LEDs as light-emitting pixel units, which are assembled on the drive panel to form a high-definition pixel unit.
Density LED array display technology. Due to the characteristics of micro LED chips such as small size, high integration and self-illumination, it has greater advantages in display compared with LCD and OLED in terms of brightness, resolution, contrast, energy consumption, service life, response speed and thermal stability.
