Solution Overview
Problem
Conventional VR display devices face issues with dynamic blur, display ghosting, and low definition due to high data transmission bandwidth and power consumption, especially when increasing refresh frequency and resolution, which negatively impact the immersive experience.
Innovation Solution
A virtual reality display device with a drive chip that decodes images with different color depths for fixation and non-fixation regions, generating specific data voltages to drive the display panel efficiently, reducing data transmission bandwidth and power consumption by applying high color depth in fixation regions and low color depth in non-fixation regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If refresh frequency and resolution of display are increased, then display quality is improved, but data transmission bandwidth and power consumption increase
Solution Approach 1:
The patent applies different color depths to different visual regions: high color depth (first color depth) is used for the fixation region where users focus attention, while low color depth (second color depth) is used for the non-fixation region. This local differentiation maintains display quality in critical areas while reducing overall data transmission bandwidth and power consumption.
2Manufacturing precision
If refresh frequency and resolution of display are increased, then display quality is improved, but data transmission bandwidth increases
Solution Approach 1:
The patent implements spatially varying color depth by dividing the display into fixation and non-fixation regions. The fixation region receives high color depth data to maintain visual quality, while the non-fixation region receives low color depth data, significantly reducing the total quantity of data transmitted without perceptible impact on user experience.
3Manufacturing precision
If high color depth is applied to entire display, then display quality is improved, but data transmission bandwidth and power consumption increase
Solution Approach 1:
The patent reduces device complexity by applying low color depth to non-fixation regions, which decreases the computational and transmission complexity of the display system while maintaining high quality in the fixation region where visual performance is critical.
