摘要： An illumination module includes a longitudinal support member including a base portion and a pair of sidewalls extending from the base portion that together define a channel that extends in a longitudinal direction. A printed circuit board (PCB) on the base portion extends in the longitudinal direction within the channel. A plurality of light emitting diodes (LEDs) are on the PCB in a linear array. A reflective sheet is within and extends across the channel, and includes a plurality of holes that correspond with locations of the LEDs on the PCB, and the LEDs are at least partially within the holes. An optical film extends across the channel above the reflective sheet and defines an optical cavity between the reflective sheet and the optical film. The optical film, the reflective sheet and the sidewalls of the support member are configured to recycle light in the optical cavity by reflecting some light emitted by the LEDs back into the optical cavity and transmitting some light emitted by the LEDs out of the optical cavity.

摘要： A liquid crystal display (LCD) device includes a pixel array including a plurality of pixels configured to display an image. The plurality of pixels respectively include a first subpixel configured to display first color image data, and a second subpixel configured to display second and third color image data. The LCD device may further include a backlight configured to emit the first, second, and/or third colors of light, and a backlight controller. The backlight controller may be configured to activate the backlight to emit the first and second colors of light at a same time to generate a first image component including a combination of the first color image data and the second color image data, and to separately emit the third color of light at a different time than the first and second colors of light to generate a second image component including the third color image data. The pixel array may be configured to display the first and second image components to provide a single image frame. Related devices and methods of operation are also discussed.

摘要： Provided are methods and apparatus for combining light emitters and devices including the same. Embodiments include methods of selecting combinations of multiple light emitters that are grouped into multiple bins. The multiple bins correspond to multiple emitter group regions in a multiple axis color space and multiple luminosity ranges. Such methods may include prioritizing multiple combinations of light emitters from at least two of the bins, each of the combinations including chromaticity values corresponding to a desired color region and a luminosity value corresponding to a specified luminosity range.
