Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile terminals with full-screen displays, external light can diffract among dense wires in the transparent display region, affecting the display and camera photography effects.
Innovation Solution
A display panel design featuring a light-shielding layer with light-shielding structures and wires arranged such that orthographic projections of the wires are within the projections of the light-shielding structures, which shield external light from reaching the wires.

Engineering Contradiction Analysis
1Area of stationary object
If the screen-to-body ratio is increased to achieve full-screen display, then the display area is improved, but external light diffraction among wires in the transparent display region worsens the display effect and camera photography
Solution Approach 1:
A light-shielding layer is introduced as an intermediary component between the transparent display region and the wires. This layer includes light-shielding structures positioned to block external light from reaching the wires, thereby preventing light diffraction while maintaining the full-screen display design
Solution Approach 2:
The light-shielding structures are selectively positioned only in the transparent display region where wires are located, rather than covering the entire display. This localized approach blocks harmful light diffraction at wire locations while preserving transparency and light transmission in other areas of the display
2Object-affected harmful factors
If light-shielding structures are added to block external light from wires, then external light diffraction is reduced, but the device structure becomes more complex
Solution Approach 1:
The light-shielding layer is integrated with the existing display panel structure, combining the light-shielding function with the display structure. The light-shielding structures are formed as part of the layered architecture, merging multiple functions into a unified structure rather than adding separate independent components
Solution Approach 2:
The light-shielding layer serves multiple functions simultaneously: it blocks external light from reaching wires to prevent diffraction, maintains the transparency of the display region, and integrates with the existing display panel architecture. This multi-functionality reduces the need for additional separate components
