Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D liquid crystal display devices face issues with brightness reduction due to opaque barriers, increased weight and thickness from additional optical components, and image interference, particularly in parallax barrier and cylindrical lens displays.
Innovation Solution
An integrated pixel structure with a light angle control structure and a reflecting structure, built into each sub-pixel unit, guides light to exit in predetermined directions without additional optical barriers, allowing for 2D/3D and single/multiple view switching without extra components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an opaque parallax barrier is installed to allocate images to different eyes, then stereo image display is enabled, but light output is blocked causing brightness reduction
Solution Approach 1:
The patent uses a light angle control structure with specific geometric shapes (triangles, trapezoids, or parallelograms) that utilize refraction and reflection of light to direct different portions of light to different eyes. This optical control mechanism replaces the opaque parallax barrier while maintaining stereo image display capability and preserving light output, thereby resolving the contradiction between enabling stereo display and maintaining panel brightness.
2Ease of operation
If additional optical components (parallax barrier or cylindrical lens layer) are added to achieve naked-eye 3D display, then stereo image capability is improved, but device weight and thickness increase
Solution Approach 1:
The patent integrates the light angle control structure directly into the liquid crystal panel assembly, merging the optical control function with the display panel itself. This integration eliminates the need for separate external optical components such as parallax barriers or cylindrical lens layers, thereby achieving naked-eye 3D display capability while reducing overall device weight and thickness.
Solution Approach 2:
The patent employs a light angle control structure with specific geometric configurations (triangles, trapezoids, parallelograms) that utilize angular refraction and reflection to direct light to different viewing angles. This dimensional approach to optical control replaces traditional external optical components, enabling stereo display without additional weight while maintaining the necessary optical functionality.
3Ease of operation
If a parallax barrier is used to allocate pixels to different eyes, then stereo view is achieved, but image interference occurs at boundaries
Solution Approach 1:
The patent uses a light angle control structure with specific geometric shapes (triangles, trapezoids, parallelograms) that utilize refraction and reflection of light to direct different portions of light to different eyes. This optical control mechanism replaces the opaque parallax barrier while maintaining stereo image display capability and preserving light output, thereby resolving the contradiction between enabling stereo display and maintaining panel brightness.

AI summary
A pixel structure, a 3D image/multiple view liquid crystal display device and a method of manufacturing the same are provided. The pixel structure comprises a first substrate, a second substrate being parallel with the first substrate, a liquid crystal layer disposed between the first substrate and the second substrate, a reflecting structure, and a light angle control structure. The reflecting structure is disposed on the first substrate, and the light angle control structure is disposed on the second substrate. The light angle control structure is configured to reflect a light entering from the first substrate to the reflecting structure, and the reflecting structure is configured to reflect the light again such that the light exits from the pixel structure in a predetermined direction.
