Transparent Cover Diaphragm for High Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices face challenges in achieving a higher screen-to-body ratio due to the formation of black edges caused by the diameter of holes in light-transmitting regions, the width of display screen wires, and the distance between the display screen and camera components, which limits the full-screen structure's integrity and aesthetic appeal.
Innovation Solution
The implementation of a diaphragm structure on the transparent cover, which reduces the diameter of the light-transmitting hole and the width of the camera module, thereby minimizing the black edge and enhancing the screen-to-body ratio by aligning the camera module's lens with the diaphragm and using a screen-printing ink layer to limit light entry, while maintaining imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a through-hole is provided in the display screen for accommodating the camera module, then the camera can be integrated into the front surface, but a black edge is formed around the hole which reduces the screen-to-body ratio and visual integrity
Solution Approach 1:
The patent transitions from a 2D planar hole structure to a 3D recessed structure by providing a recessed region in the display screen. The camera module is accommodated within this recessed region, allowing the outer surface of the display screen to remain substantially flat and visually continuous, thereby eliminating the black edge effect while maintaining camera integration capability.
Solution Approach 2:
The camera module is nested within the recessed region of the display screen. The recessed region acts as a container that houses the camera module, allowing the camera to be integrated into the front surface without protruding or creating a visible hole, thus maintaining the visual integrity of the display.
2Reliability
If the diameter of the light-transmitting hole is increased to improve light transmission for the camera, then imaging quality improves, but the black edge width increases reducing the screen-to-body ratio
Solution Approach 1:
By creating a recessed region with depth, the patent allows the light-transmitting opening to be positioned closer to the camera lens while keeping the outer display surface flat. This vertical dimensionality change enables adequate light transmission for imaging quality without increasing the horizontal diameter of the visible hole, thus preventing black edge widening.
3Area of stationary object
If the distance between the display screen and camera module is reduced to minimize the black edge, then the screen-to-body ratio improves, but imaging quality may be compromised
Solution Approach 1:
The recessed region provides a vertical space that allows the camera module to be positioned close to the display screen surface while maintaining adequate separation for imaging functionality. The depth of the recessed region enables the camera to be housed nearby without compromising imaging quality, thus achieving both a high screen-to-body ratio and reliable imaging.
4Illumination intensity
If a light-shielding structure is added around the camera hole to block light leakage, then display quality improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The light-shielding function is merged with the structural recessed region. The recessed region itself, by its geometric configuration and positioning, naturally shields light from reaching the camera from oblique angles. This integration eliminates the need for separate light-shielding components, thereby controlling light leakage while maintaining simple device structure and manufacturing process.
