Solution Overview

Problem

Electronic devices that display three-dimensional images, such as head-mounted displays, face increased power consumption when displaying full-color left-eye and right-eye images, leading to reduced usage time and potential eye fatigue.

Innovation Solution

Implementing a display driver integrated circuit that shifts the color gamut of left-eye and right-eye images by alternating colors in each image, reducing power consumption while maintaining three-dimensional image quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If full color left-eye image and right-eye image are displayed, then image quality is improved, but power consumption increases

Engineering Contradiction:

Improveimage qualityVSAvoidpower consumption

Core Design Contradiction:

Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent divides the color display into separate channels for left-eye and right-eye images, assigning different color subsets to each eye. The left-eye image uses certain color channels (e.g., red and green) while the right-eye image uses other color channels (e.g., blue and green), segmenting the full color information across two monochromatic or limited-color images that can be processed more efficiently

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different color gamuts are applied locally to different eyes based on their respective image content requirements. Each eye receives optimized color information tailored to its specific needs, with the left-eye and right-eye images having different color compositions that are then combined by the human visual system to perceive full-color three-dimensional imagery

Inventive Principle:

Principle #3Local quality

2Illumination intensity

If full color left-eye image and right-eye image are displayed, then image quality is improved, but usage time is reduced

Engineering Contradiction:

Improveimage qualityVSAvoidusage time

Core Design Contradiction:

Illumination intensityVSDuration of action of moving object

Solution Approach 1:

The color information is segmented across left-eye and right-eye images, allowing each to be displayed with reduced color complexity. This segmentation reduces the overall power consumption of the display system, thereby extending battery life and usage time while still delivering full-color perception through binocular combination

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The display system alternates between displaying left-eye image frames and right-eye image frames in a periodic manner, with each frame containing specific color information. This periodic alternation at high frequency creates the perception of simultaneous full-color display while actually reducing instantaneous power demands on the display hardware

Inventive Principle:

Principle #19Periodic action

3Illumination intensity

If full color left-eye image and right-eye image are displayed, then image quality is improved, but eye fatigue increases

Engineering Contradiction:

Improveimage qualityVSAvoideye fatigue

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

Different color compositions are applied locally to left-eye and right-eye images, optimizing the spectral content for each eye's specific viewing conditions and reducing chromatic stress. By tailoring the color gamut to each eye's requirements rather than forcing full color on both, the system reduces eye fatigue while maintaining overall image quality

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of displaying full color in both left-eye and right-eye images simultaneously, the patent inverts the conventional approach by displaying complementary or alternating color information in each eye. This inversion strategy reduces the total chromatic load on the visual system while still achieving full-color perception through the combination of the two differently-colored images

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An electronic device includes a first display panel which displays a left-eye image, a second display panel which displays a right-eye image, a display driver integrated circuit which provides left-eye output grayscale data to the first display panel and provides right-eye output grayscale data to the second display panel, and a processor which provides left-eye input grayscale data and right-eye input grayscale data to the display driver integrated circuit. Each of the left-eye image and the right-eye image includes one or two selected from a first color, a second color different from the first color, and a third color different from the first and second colors.
