Display Panel Border Lapping Rubber Frame to Resist Water Ripples
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices suffer from water ripple phenomena when pressed due to external forces causing extrusion on the display panel, leading to defects such as middle and peripheral water ripples, primarily because of the gap between the display panel border and the rubber frame.
Innovation Solution
The display panel border is designed to lap over the rubber frame, which acts as a supporter, transmitting a reacting force to counteract external forces and reduce the extrusion on the liquid crystal layer, eliminating the gap between the rubber frame and the border, thereby mitigating the water ripple effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel border is separated from the rubber frame (prior art design), then the assembly is easier to manufacture, but the display panel is vulnerable to external forces causing water ripple phenomenon
Solution Approach 1:
The display panel border is integrated with the rubber frame through a lapping structure, where the border extends beyond the display panel and laps over the rubber frame. This merging eliminates the gap between components and creates a unified support structure that effectively resists external forces and prevents water ripple phenomenon.
2Reliability
If the rubber frame thickness is increased to improve support, then the water ripple resistance improves, but the device thickness and complexity increase
Solution Approach 1:
Instead of increasing rubber frame thickness in one dimension, the solution extends the support structure in another dimension by having the display panel border lap over the rubber frame. This creates a distributed support system that enhances force resistance without proportionally increasing the rubber frame thickness.
3Reliability
If the display panel border laps over the rubber frame, then the support and water ripple resistance improve, but the manufacturing precision requirements increase
Solution Approach 1:
The lapping structure utilizes the existing thickness parameter of the display panel border to create the support function. By designing the border to naturally extend and lap over the rubber frame, the structure leverages existing dimensional parameters rather than requiring additional precision-critical interfaces or adjustment mechanisms.

Function Achieved in This Case
This configuration significantly increases the force required to induce water ripples from 1.5N to 5N, improving the display effect by reducing stress on the liquid crystal layer and enhancing the display panel's resistance to external pressures.
Implementation Method 1
a reacting force provided by the rubber frame is transmitted through the display panel border to the substrate of the display panel

AI summary
The invention refers to a technical problem of display device, and discloses a display device. The display device includes a backlight source, a rubber frame provided on the backlight source, a LGP and an optical film layer provided in the rubber frame, and shading bars lapping over the rubber frame and the optical film layer respectively, and further includes a display panel, which contains a display panel border lapping over the rubber frame. In the above technical solution, the rubber frame is used for a supporter to support the display panel. Specifically, the display panel border exposed from the display panel laps over the rubber frame, so that the rubber frame is able to support the border as a supporter when the display panel is pressed.
