Abstract
A portable information handling system integrated organic light emitting diode (OLED) display presents a compensation image having pixels illuminated at predetermined color and luminance settings. The compensation image is captured by a external camera as a calibration image and analyzed to compare pixel color and luminance provided by the OLED display with expected color and luminance to determine pixel compensation values that correct the OLED display for presentation of a uniform visual image that reproduces an intended visual image when the compensation values are applied at presentation of visual images by the OLED display.
Claims20
An information handling system comprising:
- a housing having first and second housing portions rotationally coupled by a hinge;
- a processor disposed in the housing and operable to execute instructions to process information;
- a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- a display integrated in the housing and having plural organic light emitting diode (OLED) pixels, the display operable to present visual images by illuminating the OLED pixels based upon a pixel value;
- a graphics processor interfaced with the processor and display, the graphics processor operable to process the information to generate pixel values that define visual images for presentation at the display;
- a compensation image generator operable to present a compensation image at the display having a predetermined luminance and color;
- and
- a compensation engine stored in non-transitory memory and having instructions that execute on the processor to receive a camera image taken by an external camera, the camera image capturing the display presenting the compensation image, the instructions further comparing the camera image and the compensation image to calibrate color and luminance presented at the OLED pixels .
A method for compensating an information handling system display presentation of visual images, the method comprising:
- generating a compensation image at the display having a predetermined luminance and color at each of plural organic light emitting diode (OLED) pixels of the display;
- capturing a camera image of the display presenting the compensation image, the capturing performed by an external camera;
- comparing the compensation image and the camera image to determine calibration information that calibrates color and luminance presented at the OLED pixels;
- and
- applying the calibration information to adjust the color and luminance of the OLED pixels for presentation of content as visual images.
A portable information handling system comprising:
- a processor operable to execute instructions to process information;
- memory operable to store the information and instructions;
- a camera interfaced with the processor and operable to capture an image of an information handling system having an integrated organic light emitting diode (OLED) display presenting a compensation image;
- a communication medium operable to communicate with the information handling system having the integrated OLED display;
- and
- a non-transitory memory operable to store instructions that execute on the processor to:
- retrieve through the communication medium a compensation visual image presented at the OLED display;
- capture a calibration picture of the OLED display with the camera;
- compare color and luminance of the OLED pixels detected in the calibration picture with color and luminance of the compensation visual image to determine calibration information defining adjustments to pixel values applied to the OLED display;
- and
- communicate the calibration information through the communication medium.
