Solution Overview
Problem
Traditional slidable flexible display devices face issues such as sinking in touch areas, poor weather resistance, and material creep under pretension, leading to damage like wrinkles or creases due to unstable foaming materials and irreversible plastic deformation.
Innovation Solution
A slidable display device design featuring a housing assembly with a linkage mechanism, a network structure formed by staggered support strips and ribs, and an adhesive layer for improved support and temperature resistance, minimizing unsupported areas and preventing damage during touch control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If groove-shaped support structures are used in expanded state, then the display device can be slidably expanded, but the supportability deteriorates causing sinking in gaps by touch control
Solution Approach 1:
The support structure is segmented into multiple ribs arranged at intervals, which divide the display surface into multiple supported regions. This segmentation allows the display to be expanded while providing localized support at each rib position, preventing sinking in the gaps between ribs.
Solution Approach 2:
The support structure transitions from a single-plane groove shape to a three-dimensional configuration with ribs extending vertically. This dimensional change creates multiple support levels that maintain structural integrity during sliding expansion while preventing touch-induced sinking.
2Ease of operation
If traditional foaming materials are used for cushioning, then cushioning is provided, but characteristics change under high temperature and high humidity or low temperature resulting in unstable performance and peeling or cracking
Solution Approach 1:
The material parameters of the cushioning layer are changed by selecting materials with stable physical and chemical properties across a wide temperature range. This ensures that the cushioning characteristics remain consistent under high temperature, high humidity, or low temperature conditions, preventing peeling or cracking.
Solution Approach 2:
A composite cushioning structure is used, combining materials with complementary properties to achieve both cushioning functionality and environmental stability. The composite structure maintains stable characteristics under varying temperature and humidity conditions while providing necessary cushioning for the display device.
3Stability of the object's composition
If pre-tension is applied to whole scroll screen display terminals, then structural stability is maintained, but materials such as polymers are prone to irreversible plastic deformation and creep resulting in wrinkles or creases
Solution Approach 1:
Instead of applying uniform pre-tension to the entire display, localized support structures (ribs and support plates) are positioned at specific locations to provide targeted structural stability. This local quality approach maintains stability while avoiding excessive pre-tension on polymer materials, preventing plastic deformation and creep that would cause wrinkles or creases.

AI summary
A sliding display device includes a housing assembly and a flexible display screen. The housing assembly includes a bottom case, a first support body, a second support body, and a linkage mechanism. The linkage mechanism is configured to drive the second support body to slide out of the bottom case into an expanded state or slide into the bottom case into an unexpanded state. Part of the flexible display screen is hidden between the bottom case and the first supporting body in the unexpanded state. The flexible display screen includes a flexible display panel, a backplate, an adhesive layer, and at least a third support body. The third support body and the second support body collectively form a network structure.
