Flexible Glass Substrate for Mobile Terminal Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible OLED displays have low light transmittance, typically below 70%, which is insufficient for camera imaging quality, and the PI base material's yellow color does not meet imaging requirements, while curved displays lack adequate support during fastening.
Innovation Solution
A flexible display panel using a flexible glass substrate with a display module and an encapsulation layer, featuring a through hole for improved light transmission and a bending structure for support, allowing the panel to form an arc-shaped display without needing holes in the substrate, enhancing both light transmission and structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a PI base material is used in flexible OLED, then flexibility is achieved, but light transmittance decreases to 70% or lower
Solution Approach 1:
The patent changes the material parameter from PI base material to flexible glass substrate, which fundamentally alters the light transmittance property while maintaining flexibility. The flexible glass substrate achieves both flexibility and high light transmittance (above 85%) by changing the material composition and structure parameters.
2Illumination intensity
If holes are drilled on the substrate for light transmission, then light transmittance improves, but structural support deteriorates
Solution Approach 1:
The patent extracts the light transmission function from the substrate structure itself and relocates it to a dedicated light transmission hole in the support component. This separation allows the substrate to maintain its structural integrity while the support component provides the light transmission pathway, resolving the conflict between structural support and light transmission.
3Device complexity
If curved display is fastened without adequate support, then device complexity is reduced, but reliability deteriorates as the arched bending part cannot be well supported
Solution Approach 1:
The patent introduces a support component with an arc-shaped support surface as an intermediary between the flexible display panel and the device housing. This intermediary component provides the necessary support for the arched bending part, ensuring reliability while maintaining relatively simple device structure. The support component acts as a mediator that distributes mechanical stress and maintains the curved display's position.

AI summary
This application provides a flexible display panel and a mobile terminal. The flexible display panel is applied to the mobile terminal. The flexible display panel mainly includes a flexible glass substrate and a display module disposed on the flexible glass substrate. The flexible glass substrate is used as a support structure, and a first bending structure is disposed on each of two opposite edges of the flexible glass substrate. The flexible display panel forms an arc-shaped display panel when the display module is supported. In addition, the flexible display panel further includes an encapsulation layer, where the encapsulation layer encapsulates the display module on the flexible glass substrate. For the flexible display panel, the flexible glass substrate is used to carry the display module, thereby improving transparency of the entire flexible display panel. When a buried device is used in the mobile terminal, the flexible glass substrate is used to improve light transmission performance of the entire flexible display panel, thereby improving a use effect of the mobile terminal.
