Curved Surface Adjustment Mechanism for TV Backlight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curved surface TVs suffer from visual distortion and inconsistent viewing experience due to the size and shape of the screen, which affects the overall viewing experience, especially as the viewer moves away from the center.
Innovation Solution
A curved surface adjustment mechanism comprising a support, backplate, and adjustment assembly that allows for the sliding block and link to convert between curved and flat display states, enabling seamless switching between display effects by constraining the backplate's movement and utilizing sawtooth surfaces and guide strips for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a curved screen is used to improve viewing experience, then visual comfort at center position is improved, but visual distortion occurs at peripheral positions
Solution Approach 1:
The patent applies the dynamics principle by making the screen surface adjustable between curved and flat states. The backplate can be dynamically changed from a curved configuration (providing central visual comfort) to a flat configuration (eliminating peripheral distortion), allowing the display to adapt to different viewing requirements.
2Ease of operation
If a fixed curved screen is used, then visual experience at center is improved, but adaptability to different viewing positions is reduced
Solution Approach 1:
The adjustable mechanism enables the screen to dynamically switch between curved and flat configurations, providing adaptability to different viewing positions and scenarios.
Solution Approach 2:
The patent changes the geometric parameter of the screen surface (curvature radius) by adjusting the backplate configuration. The screen can transition from a curved state with a specific radius to a flat state, thereby adapting to different viewing requirements.
3Adaptability or versatility
If an adjustment mechanism is added to enable switching between curved and flat states, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into modular components: a support structure with guide strips, a backplate with corresponding guide grooves, and limiting mechanisms. This segmentation allows for easier assembly, maintenance, and manufacturing while achieving the desired adaptability.

AI summary
The present invention discloses a curved surface adjusting mechanism, which comprises a support, a backplate and an adjustment assembly; the support comprising two first frame portions opposite to each other; the adjusting assembly comprising a sliding block and a link hinged with the sliding block, the free end of the link hinged with the long side wall of the backplate, the sliding block which can slide along the longitudinal direction of the backplate. The present invention further discloses a backlight module. In the invention, a support is designed outside the backplate, and a slidable sliding block and a link connecting to the backplate are arranged between the support and the backplate. By the movement of the slider, it can freely switch the curved and flat states of the backplate, so that the surface display effect and flat display effect of TV can be converted more conveniently and efficiently.
