Today the anti-static layer sits not on the screen but on the protective film that gets peeled off and thrown away. Static is generated at the very surface that separates, so the anti-static layer moved from the base film to the adhesive face, and every reduction in static brought contamination and corrosion with it. The mainstream PEDOT:PSS is expensive but survived because it is used as thin as 0.03 micrometers, while CNT, which meets the same condition, still has to clear the wall of dispersion.
Until now, metasurface holograms needed a laser. Researchers at the University of Toronto produced them with a halogen lamp. A Q-200 resonance compresses a 300-nanometer band to under 4 nanometers, so the device generates coherence itself. That flips the strengths and weaknesses of laser holograms: speckle averages itself out and shrinks, while thin strokes blur.
Of the 7 patents LG Display asserted against Tianma, the only one Tianma tried to invalidate at the US Patent Office was a Y-OCTA structure patent. That patent was granted on the two lines left after Samsung prior art stripped away the rest, and when Tianma came back armed with Samsung documents again, its petition never reached a technical hearing. What shut the door was an ownership structure that brought AVIC in back in 2011.
From September 27 to October 4, 28 major journals were checked in full and narrowed to 128 papers with a display connection, of which 15 are introduced here. Two in-depth articles are covered separately. This window brought together work on bringing the screen close to the eye and on the lifetime and efficiency of blue OLEDs.
Researchers at Kyung Hee University made the internal light-extraction structure of a top-emitting microcavity OLED gentler. A more deeply etched microlens array sent only 43.5% of the light forward; a gentle corrugation sent 77.3%. Even with low roughness, a steep local slope unsettled the cavity. The result says that disturbing the cavity less comes before scattering harder.
Liquid crystals are highly sensitive to temperature — a property displays have spent decades trying to erase. An Italian team turned that sensitivity into a signal, building a capacitive sensor with a liquid-crystal gel dielectric fabricated on ordinary LC panel-line equipment, one that kept working submerged in water and bent. What set sensitivity apart wasn't how much liquid crystal was loaded, but the phase it was in when cured.
Moth-eye fills the missing refractive index of 1.23 with shape instead of material. Even when bump height is identical, a different profile can split reflectance by a factor of two, and that profile is set entirely by the voltage and etching used to carve the mold. But the same nanoscale gaps trap fingerprint oil that a dry cloth cannot wipe away, so the technology has settled not on the outside of a screen but in places hands never touch.
From September 20 to 27, 1,220 papers published in 28 major journals were checked and narrowed to 119 with a display connection, of which 15 are briefly introduced here. Two more are covered as separate in-depth articles. This window brought together the process of making pixels and the problems that show up when pixels are made smaller.
