Flexible Display Panel Wrapping Housing for Full-Screen Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current full-screen display devices face challenges in increasing the screen-to-body ratio due to the presence of front cameras and speakers, which require complex design and production processes, and existing solutions either demand strict acoustic design or high-technique opening drilling, limiting further improvements.
Innovation Solution
A flexible display panel with splicing end surfaces featuring recesses that allow the flexible panel to wrap around a housing, creating grooves for camera and speaker placement on the back, reducing design complexity and enabling a full-screen design by covering the front surface completely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional hard screen design is used, then routing space is provided for driver IC, but the screen-to-body ratio cannot be maximized due to required bonding area and outer frame portions
Solution Approach 1:
The flexible display panel is bent from a two-dimensional flat structure into a three-dimensional configuration that wraps around the housing. The panel extends from the front surface, wraps around the side edges, and continues to the back surface, utilizing the third dimension (depth/thickness) to relocate routing areas away from the front display area, thereby achieving maximum screen-to-body ratio without sacrificing manufacturing capability
Solution Approach 2:
A flexible display panel with bending capability is employed instead of a rigid hard screen. This flexible panel can be conformally wrapped around the housing structure, allowing the routing areas (first and second routing areas) to be positioned on the back and side surfaces while maintaining full front surface display coverage. The flexibility enables the panel to adapt to the housing geometry without requiring additional outer frames or bonding areas on the front
2Manufacturing precision
If front camera and speaker are placed at top front, then display area is occupied, but screen-to-body ratio improvement is limited
Solution Approach 1:
The front camera and speaker are relocated from the front surface (two-dimensional plane) to the back surface of the housing by utilizing the flexible panel's wrapping capability. The panel is bent such that the areas corresponding to the camera and speaker positions on the front are continuous with routing areas on the back, effectively moving these components to the rear of the device. This dimensional transition eliminates their occupation of front display area while maintaining full-screen appearance
Solution Approach 2:
The front camera and speaker are extracted from the front display area and repositioned to the back of the housing. The flexible panel structure allows the routing for these components to be separated from the front viewing area, with the panel wrapping around to provide continuous coverage. This extraction eliminates the need for cutouts or notches in the front display, achieving true full-screen ratio
3Manufacturing precision
If special-shaped screen with slot or opening is used, then screen-to-body ratio increases, but design difficulty and manufacturing complexity increase
Solution Approach 1:
The flexible display panel is segmented into multiple functional areas: a first display area on the front, a first routing area on the back for driver IC bonding, a second display area wrapping around the sides, and a second routing area on the back for antenna placement. This segmentation allows each area to be optimized independently while maintaining continuous panel coverage, eliminating the need for complex routing designs around slots or openings in the front display

AI summary
The invention provides a full-screen display device based on flexible display panel, comprising a housing and a flexible display panel; a first and a second recesses penetrating the flexible display panel in thickness direction being disposed respectively at splicing ends at both ends of the flexible display panel; the two ends of the flexible display panel being spliced together on back of the housing to simultaneously wrap front and back of the housing to form a first display portion covering the front of the housing and a second display portion covering the back of the housing; and the first recess and the second recess communicating and surrounding to form a groove provided for a first element on the housing to pass through. Since the splicing ends of the flexible display panel are located on the back of the housing, the speaker and camera can be placed on the back display.
