At CES 2024, the South Korean tech giant Samsung Display revealed information about the RGB OLEDOS. Pixel density is 3500PPI, RGB Olledos from Imagine, an American company acquired by Samsung Display last year, will also be exhibited.
Samsung Display will present red (R) green (G) blue (B) OLEDoS (OLED on Silicon) for extended reality (XR) devices and foldable organic light emitting diode (OLED) at CES held in the United States.
RGB Olledos is Olledos that implements both light and color in RGB subpixels. Vision Pro, a mixed reality (MR) device scheduled to be released by Apple early this year, uses WOLED+CF OLEDOS, which applies an RGB color filter (CF) to white (W)-OLED. WOLED+CF Oledos produces color as white light from WOLED passes through an RGB color filter.
RGB Olledos, which Samsung Display is unveiling at CES, is 1.03 inches and is the size of a 500 won coin. The pixel density is 3500PPI (Pixels Per Inch), supporting a resolution similar to that of a 4K TV.
‘Rollable Flex’, where the panel rolls and unwinds like a roll of toilet paper to expand up to 5 times, ‘Flex Hybrid’, which combines two foldable and slideable technologies, and a wireless earphone case with display. etc. are also displayed.
Samsung Display said, “The thickness of the ultra-thin ultra-thin (UT) OLED panel is about 0.6mm, similar to a business card, and is about one-third of a liquid crystal display (LCD) panel of the same size,” adding, “The weight of three UT OLED panels is the same size. “It is light enough to be similar to the weight of one LCD panel,” he explained. He continued, “By applying a new module construction method, the thickness has been reduced while maintaining strength,” and added, “It will contribute to laptop and tablet manufacturers increasing portability and differentiating designs.”
Samsung Display said, “When developing a new thin film transistor (TFT) that controls current flow, we applied only 100% oxide. Oxide moves electrons about 10 times faster than amorphous silicon (a-Si) and has low current leakage.” “This is small,” he said. He added, “If current leakage is reduced, the flicker phenomenon, where the screen flickers and trembles slightly when the display is driven at a low refresh rate, can be resolved, which has the effect of further reducing power consumption through the low refresh rate.” He continued, “The product released this time is the first IT panel to support a variable refresh rate of as low as 1Hz.”
