Solution Overview
Problem
As mobile terminals become increasingly feature-rich, the space constraint often leads to a reduction in display area, and existing solutions fail to effectively integrate optical components like cameras and sensors without occupying additional space.
Innovation Solution
A terminal display assembly that includes a display screen with a through hole for optical components, a light-transmission cover plate, and a seal ring to prevent dust and light leakage, allowing for signal transmission without occupying additional space and maintaining the terminal's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more components are disposed on the mobile terminal face where the screen is mounted, then the functionality of the mobile terminal is enhanced, but the display area of the screen is reduced
Solution Approach 1:
The patent integrates optical components (camera, sensor) through the display screen by creating through-holes in the display structure, effectively utilizing the depth dimension and rear surface space rather than adding components on the front face. This allows components to be embedded within the display assembly thickness, preserving the front display area while enabling enhanced functionality.
Solution Approach 2:
The optical components are nested within the display assembly structure, with the camera and sensor positioned in through-holes that penetrate the display screen. The seal ring is nested around these components, and the light-transmission cover plate is positioned above the through-holes. This nested arrangement allows multiple functional elements to coexist within the limited space of the display assembly without compromising the display area.
2Area of stationary object
If optical components are integrated through the display screen, then the display area is increased, but dust and light leakage may occur
Solution Approach 1:
The seal ring serves as an intermediary element positioned around the optical components within the through-holes. It creates a sealing barrier between the optical components and the external environment, preventing dust ingress and blocking stray light from reaching the optical sensors. The light-transmission cover plate positioned above the through-holes acts as another intermediary that allows light transmission for the display while blocking stray light from entering the through-holes.
3Reliability
If the seal ring thickness is greater than the optical adhesive thickness, then the sealing effect is improved, but the assembly complexity increases
Solution Approach 1:
The patent specifies a parameter relationship where the seal ring thickness is greater than the optical adhesive thickness. This parameter change ensures that the seal ring protrudes beyond the adhesive layer, providing a reliable sealing barrier that prevents dust and light leakage. The increased thickness of the seal ring relative to the adhesive creates a stepped structure that simplifies the assembly process by providing clear positioning and engagement features.
