Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lenticular lens or parallax barrier is used to distribute images to multiple viewpoints, then stereoscopic display capability is achieved, but luminance deterioration and pattern superimposition occur when viewed from different angles
Solution Approach 1:
The patent applies local quality by making each pixel emit light with a specific angular distribution tailored to its position. Pixels are controlled to direct light preferentially toward intended viewpoint directions, creating localized optical characteristics that collectively achieve uniform luminance across multiple viewing angles while maintaining stereoscopic capability
Solution Approach 2:
The patent implements dynamics by enabling each pixel to dynamically adjust its light emission pattern based on its position in the display. The light emitting elements can change their radiation characteristics in response to positional information, allowing the display to adapt its optical properties for different viewing directions and maintain consistent luminance
2Adaptability or versatility
If pixels are arranged to display images for multiple viewpoints, then multi-viewpoint display is achieved, but image quality deteriorates due to uneven reflection structures
Solution Approach 1:
The patent applies local quality by assigning different light emission patterns to pixels based on their specific positions. Each pixel is configured to emit light in directions appropriate for its location, ensuring that the collective output maintains high image quality across all viewpoints without requiring uniform reflection structures
Solution Approach 2:
The patent replaces mechanical/optical structures (such as complex reflection plates or microlens arrays) with a controllable light emitting system. By using individually controllable light emitting elements, the system achieves precise light direction control without the manufacturing complexity and precision requirements of traditional optical components
3Ease of manufacture
If conventional techniques are used for manufacturing the display panel, then manufacturing simplicity is maintained, but high-definition display quality cannot be achieved
Solution Approach 1:
The patent applies self-service by enabling each pixel to automatically determine and execute its appropriate light emission pattern based on its position. The system uses positional information to self-configure its optical characteristics, eliminating the need for complex external optical components and simplifying manufacturing while achieving high-definition display quality
Solution Approach 2:
The patent implements parameter changes by varying the light emission characteristics of pixels based on their positional parameters. By changing emission intensity, angle, and timing according to position, the system achieves high-definition multi-viewpoint display using conventional manufacturing techniques without requiring precision optical components

AI summary
A display panel, a display device, and a terminal device, which can achieve a high image quality by decreasing deterioration of the image quality that may be caused due to combining a reflection plate including an uneven structure with an image distributing device, are provided. The display panel includes a lenticular lens for distributing light emitted from each of pixels towards different directions from each other along an arranging direction (a first direction) of a pixel for displaying an image for a first viewpoint and a pixel for displaying an image for a second viewpoint within a pixel unit, wherein a reflection plate including an uneven structure is formed in each of the pixels, and a layout pattern of the uneven structure on the reflection plate is different to the lenticular lens.
