CORRECTING IMAGERY WITH DIFFERENTIAL APPLIED SCALARS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18059322 titled 'CORRECTING IMAGERY WITH DIFFERENTIAL APPLIED SCALARS

Simplified Explanation

The patent application describes a method for compensating pixel degradation by applying different scalars to adjust the drive current of each pixel in an image display system.

• The input image data is associated with a commanded luminance for each pixel.
• A degradation value is determined for each pixel to assess the pixel's condition.
• An elevated drive current is calculated based on the degradation value to maintain the commanded luminance.
• A required scalar is determined for each pixel to prevent the elevated drive current from exceeding a threshold.
• An applied scalar is calculated for each pixel to adjust the drive current accordingly.
• The applied scalar for a pixel may be influenced by the required scalar of neighboring pixels and their spatial relationship.
• The corrected imagery is then output using the applied scalars.

Potential Applications

This technology can be applied in various display systems such as televisions, monitors, and digital signage to enhance image quality and compensate for pixel degradation over time.

Problems Solved

This innovation addresses the issue of pixel degradation in display systems, ensuring consistent image quality and preventing overdriving of pixels, which can lead to reduced lifespan and image distortion.

Benefits

Potential Commercial Applications

Commercial applications of this technology include consumer electronics, professional displays, medical imaging devices, and automotive displays, where high-quality imagery is essential for user satisfaction and product performance.

Possible Prior Art

One possible prior art for this technology could be existing methods for compensating pixel degradation in display systems, such as dynamic backlight control or pixel-level dimming techniques.

How does this technology impact power consumption in display systems?

This technology could potentially optimize power consumption by adjusting drive currents based on pixel degradation, but the exact impact on power efficiency is not explicitly addressed in the abstract.

Can this method be applied to different types of display technologies, such as OLED or microLED displays?

The abstract does not specify the compatibility of this method with specific display technologies, leaving room for further exploration into its applicability across different display types.

Original Abstract Submitted

Disclosed is the differential application of scalars to compensate pixel degradation. Input image data is associated with a commanded luminance at each of a plurality of pixels. A degradation value is determined for each pixel. Based on the degradation value, an elevated drive current is determined to produce commanded luminance at the pixel. A required scalar is determined for each pixel to hold the elevated drive current from exceeding a drive current threshold. An applied scalar for each pixel is determined for each pixel to be applied to the elevated drive current. For at least some pixels, the applied scalar for a first pixel is based at least on [I] the required scalar of a second pixel and [] a spatial relationship between the first pixel and the second pixel. Applied scalars are then used to output corrected imagery.
