Scrollable Flexible Display Support Bars for Panel Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels in display devices experience unevenness and poor display quality due to internal stress during unrolling, affecting the overall display effect.
Innovation Solution
The implementation of support columns on the rear face of the flexible display panel, slidably connected to a second housing, along with a tension structure and a reel mechanism, ensures uniform support and maintains panel flatness, reducing unevenness and enhancing display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a liquid crystal display is used, then power consumption is reduced and viewing angle is improved, but response time becomes insufficient for fast-moving images
Solution Approach 1:
The pixel electrode is divided into multiple segments (first pixel electrode and second pixel electrode) that can be independently controlled. This segmentation allows different regions of the same pixel to display different grayscale levels, enabling faster response times while maintaining the power efficiency and viewing angle benefits of liquid crystal display technology.
Solution Approach 2:
The patent implements dynamic control of pixel electrodes by applying different voltages to the first and second pixel electrodes based on the motion detection results. This dynamic adjustment allows the display to adapt response times to actual image content, using faster response for moving images and standard response for static images, thereby resolving the speed limitation while preserving energy efficiency.
2Speed
If motion detection and compensation are implemented, then fast-moving image display is improved, but device complexity increases
Solution Approach 1:
The motion detection function is integrated directly into the display device, combining the detection and compensation functions within a single system. This merging approach enables fast-moving image display through coordinated control of multiple pixel electrodes while avoiding the need for separate, complex external motion compensation systems.

AI summary
The present application belongs to the technical field of displays. Disclosed is a display apparatus. The display apparatus comprises a first housing, at least one second housing, a flexible display panel, a scroll, and a plurality of support bars. The plurality of support bars are arranged on the back surface of the scrolled display portion of the flexible display panel, the two ends of the plurality of support bars being in slide connection to the second housing correspondingly. Thus, the plurality of support bars can effectively support the flexible display panel, and can limit the degree of freedom of the flexible display panel in the Y-axis direction when cooperating with the second housing, so as to effectively lower the probability of the flexible display panel exhibiting undesirable unevenness, thereby allowing the flexible display panel to have a relatively good overall flatness, and further allowing the display apparatus to have a relatively good display effect.
