Abstract: An optoelectronic device includes a backlight panel illuminating a display panel. The backlight panel includes an array of light emitting pixels, with each light emitting pixel including at least one subpixel formed by one or more light emitting diodes positioned on a substrate. At least one photodetector is positioned on the substrate and arranged to detect an amount of reflected light emitted by said subpixel and reflected by the display panel.

Abstract: A non-emissive display includes a backlight controller sending a pulse during each sub-frame of a plurality of frames to row and column drivers that drive backlight zones. The row drivers count each pulse to keep a pulse count total, and reset the pulse count total when it is equal to a first number indicating how many row drivers are present. Each row driver activates its channels and waits for a next pulse if the pulse count total is not equal to the first number and if the pulse count total is equal to a second number indicating in which sub-frame that first driver is to be activated. Each row driver waits for a next pulse if the pulse count total is not equal to the first number and the second number. Each column driver activates its channel in response to receipt of each pulse.

Abstract: An optoelectronic device includes a backlight panel illuminating a display panel. The backlight panel includes an array of light emitting pixels, each light emitting pixel having at least one subpixel with one or more light emitting diodes positioned on a substrate. The pixel further includes at least one photodetector positioned on the substrate and arranged to detect an amount of reflected light emitted by said subpixel and reflected by the display panel.

Abstract: Display elements, each having anode and cathode terminals, are arranged into rows and columns. Each row has an anode-line coupled to the anode terminals for its display elements. Each column has a cathode-line coupled to the cathode terminals for its display elements. A switch for each anode-line selectively couples that anode-line to a storage capacitor, and a switch for each cathode-line selectively couples that cathode-line to the storage capacitor. A display driver activates the row driver for a given row and the column driver for a given column. A switch driver closes the switch for the cathode-line for the given column, then opens the switch for that cathode-line. The display driver deactivates the row driver for the given row, after closing the switch for the cathode-line for the given column. The switch driver closes the switch for the anode-line for the given row.
