Abstract: A camera colorimeter system simultaneously lights up one or more pixel units on a display panel, each pixel unit including colored subpixels, for characterization of the display panel. The system includes optical elements that directs the light emitted by the simultaneously lit one or more pixel units to a filter and a corresponding imaging device. Each filter is configured to block wavelengths of light other than predetermined range of wavelengths, thereby ensuring that each imaging device captures a filtered spectrum of light that originates from subpixels of the same color. Using the filtered spectrum, the system reconstructs the full spectrum of light, which can subsequently be used to regenerate the display characteristics of each pixel unit (and corresponding colored subpixels). Thus, the camera colorimeter system can characterize a display panel in significantly less time as compared to conventional systems and methods.

Abstract: Embodiments relate to determining characteristics of a display panel by using capturing images through multiple filters where the multiple filters include at least two filters that collectively enable replicating of a color matching function. At least two filters of the multiple filters have transmission profiles that correspond to the same color matching function (x color matching function) in different wavelength ranges. Image capturing devices capture the display panel through respective filters. The captured images are processed to the display characteristics of pixels or regions of the display panel.

Abstract: A display calibration apparatus may include a display mounting assembly with a mounting platform and a multi-axis positioning device coupled to the mounting platform for adjusting an orientation of the mounting platform. The display calibration apparatus may also include a camera device positioned to receive light emitted by a plurality of sub-pixels of a display mounted on the mounting platform. The camera device may include an image sensor array that captures light emitted by the plurality of sub-pixels of the display. In addition, the display calibration apparatus may include a camera lens and a focuser. The camera lens may be positioned to direct light emitted by the plurality of sub-pixels of the display onto the image sensor array of the camera device, and the focuser may be disposed between the camera device and the camera lens to move the camera lens axially along an optical axis of the camera lens.

Abstract: An apparatus for measuring characteristics of an electronic display panel includes an array of optical elements. Each optical element has a first surface and a second surface. The first surface faces the electronic display panel and receives light from pixels of the electronic display panel. The second surface faces away from the electronic display panel and has an area smaller than the area of the first surface. The second surface emits a combined version of the light received by the first surface. The apparatus further includes a light sensor facing the second surface to measure one or more parameters of the emitted light.

Abstract: A system calibrates luminance of an electronic display panel. The system includes a luminance detection device, an actuator and a computing device. The luminance detection device comprises a plurality of detectors arranged along a width or length of the electronic display panel to simultaneously measure luminance parameters of at least one row or column of areas in the electronic display panel. Each of the plurality of detectors covers an area in the at least one row or column of the electronic display panel. The actuator is configured to cause a relative translational movement in a length direction or a width direction of the electronic display panel. The computing device is coupled to the luminance detection device to receive the measured luminance parameters, and the computing device is configured to generate calibration data for adjusting brightness of areas of the electronic display panel by processing the measured luminance parameters.

Abstract: An apparatus for treating pixels or regions of a display panel includes a measuring device configured to measure a parameter of light emitted by one or more pixels of each region of the display panel. The apparatus includes a parameter comparator operably coupled to the measuring device and configured to select one or more pixels or one or more regions of the display panel such that the measured parameter of light emitted by the one or more pixels or the one or more regions exceeds a threshold value. The apparatus also includes a laser device configured to emit a laser beam onto the selected one or more pixels or the selected one or more regions.
