The present application relates to light-emitting diode (LED) driver circuits, display devices, and display systems. An example LED driver circuit includes: a driver including a plurality of data channels; a controller electrically connected to the driver. The controller is configured to, in response to detecting that data in all the data channels is 0 in a predetermined time period, control all the data channels to be in a closed state. The predetermined time period is determined based on a duration of an external input signal input to the LED driver circuit.

An automatic driver-dimming-mode detection protocol includes subjecting, via a dimming bus, a luminaire driver to a first driver control signal of test analog voltages. Forcing the luminaire driver, via the first driver control signal, into a power output response that includes: (a) a constant output power mode, or (b) at least two discernable different output power levels. Detecting a dimming mode of the luminaire driver. The step of detecting the dimming mode of the luminaire driver includes: measuring, via a power metering circuit, a power metering measurement corresponding to the power output response; and based on the power metering measurement of the luminaire driver being: (a) the constant output power mode, determining that the luminaire driver is a digital dimming mode type (e.g., DALI), or (b) the at least two discernable different output power levels, determining that the luminaire driver is an analog dimming mode type (e.g., 0-10V).

A spectral power distribution (SPD) fusion lighting apparatus includes a first visible light source with a first SPD, a second visible light source with a second SPD, a driver circuit, and a controller. The first SPD is different than the second SPD markedly in a 50 nm wavelength range. The controller toggles the turning on of the first visible light and the second visible light at a frequency greater than 25 Hz. The first visible light source is turned on during one half of the duty cycle, whereas the second visible light source is turned on during the other half of the duty cycle. The first visible light source and the second visible light emit similar light outputs and have similar chromaticity coordinates on the CIE 1931 color space chromaticity diagram. In some embodiments a sound wave generator is used to generate a sound wave at the same frequency.
