Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to increase the display area of mobile terminals without expanding their size, while minimizing interference from light rays that can affect optical devices like cameras during illumination.
Innovation Solution
A terminal display assembly featuring a display screen with a first through hole for optical devices, covered by a first light-transmissive cover plate with a second through hole, and a light-shielding member to block light rays, ensuring that optical devices can transmit signals without occupying additional space and reducing glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If optical devices such as cameras and sensors are mounted on the display screen to transmit signals without occupying additional space, then the display area is increased, but light rays from the display screen may refract or reflect into the optical devices causing interference
Solution Approach 1:
The patent divides the cover plate structure into multiple segments: a first light-transmissive cover plate with a first through hole for optical devices, and a second light-transmissive cover plate with a second through hole larger than the first. This segmentation allows the display screen to be divided into a display area and a non-display area, enabling optical devices to be mounted on the display screen while maintaining display functionality. The segmented structure resolves the contradiction by providing separate functional zones that prevent light ray interference while preserving display area.
Solution Approach 2:
The patent introduces a light-shielding member as an intermediary element positioned between the display screen and the optical devices. This light-shielding member blocks light rays that would otherwise refract or reflect into the optical devices, preventing interference while allowing the optical devices to be mounted on the display screen. The intermediary structure resolves the contradiction by actively blocking harmful light rays while maintaining the spatial arrangement that increases display area.
2Area of stationary object
If the size of the mobile terminal remains unchanged, then portability is maintained, but the display area tends to be sacrificed and reduced
Solution Approach 1:
The patent utilizes the third dimension (thickness direction) by creating through holes that penetrate the display screen and cover plates. This dimensional approach allows optical devices to be mounted within the thickness of the terminal rather than occupying additional lateral space. By transitioning from a two-dimensional surface mounting to a three-dimensional through-hole mounting, the patent increases display area while maintaining the terminal's external dimensions, thus resolving the contradiction between display area and terminal size.

AI summary
The present disclosure provides a terminal display assembly (200) and a mobile terminal (20). The terminal display assembly (200) includes a display screen (22), a first light-transmissive cover plate (21), a light-shielding member (28), and a second light-transmissive cover plate (27). The display screen (22) defines a first through hole (221). The first light-transmissive cover plate (21) is provided on and covers the display screen (22) and defines a second through hole (211). The second through hole (211) has a size larger than that of the first through hole (221) to form a supporting surface (222) on the display screen (22). The light-shielding member (28) has a bottom wall (281) and a side wall (282) that define a receiving space (284). The bottom wall (281) is provided on the supporting surface (222) and has a third through hole (283). The third, second, and first through holes are in communication with each other. The second light-transmissive cover plate (27) is provided within the receiving space (284) to cover the first and third through holes.
