Cited, deeply-sourced entries on the terms that come up in home theater spec sheets, room calibration, and panel-tech debates. Each entry pairs an atomic definition with mechanism, worked example, current product or standards mapping, and primary-source citations.
MLA
— Micro Lens ArrayLast verified 2026-04-25MLA is a microscopic lens layer added on top of WOLED pixels that redirects light emitted at oblique angles back toward the viewer. It raises peak HDR brightness by roughly 60 to 70 percent over a non-MLA panel of the same OLED chemistry, without changing the underlying emitter material or driving scheme.
QD-OLED
— Quantum Dot OLEDLast verified 2026-04-25QD-OLED is an OLED panel architecture that uses a blue OLED emission layer combined with quantum-dot color-conversion films for red and green, instead of the white OLED plus color-filter approach used by traditional WOLED. The conversion approach produces wider color volume and higher saturation at full luminance than WOLED of the same generation.
RT60
— Reverberation Time (60 dB decay)Last verified 2026-04-25RT60 is the time, in seconds, for a sound's energy to decay by 60 decibels after the source stops. It quantifies how reverberant a room is and is the primary single-number descriptor of room acoustics in the standards used for listening rooms (ITU-R BS.1116) and recording studios.
SBIR
— Speaker-Boundary Interference ResponseLast verified 2026-04-25SBIR is a frequency-response notch caused by sound reflecting off a nearby wall, floor, or ceiling and arriving out of phase with the direct sound at the listening position. The cancellation lands at the frequency whose quarter-wavelength equals the boundary distance, producing a measured dip of 6 to 15 dB.
