Curved Display Device for Variable Stereoscopic Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices that utilize eyeglasses with shutters or parallax barriers face challenges in providing a strong stereoscopic effect for two-dimensional images, leading to increased power consumption and reduced pixel density, which limits the ability to display high-definition images with a sense of depth.
Innovation Solution
A display device with a curved display portion and a frame portion that can be adjusted in curvature, inclination, and size, allowing for a variable stereoscopic effect by analyzing image data to generate control signals that change the display's curvature and shape, enhancing the sense of depth without fatigue.

Engineering Contradiction Analysis
1Reliability
If a display device uses eyeglasses with shutters to display stereoscopic images, then the viewer can see a stereoscopic image, but the frequency of image writing to the pixel portion increases and power consumption increases
Solution Approach 1:
The patent applies the dynamics principle by making the display surface curvature variable rather than fixed. The display surface can dynamically change its curvature state between a first curvature (for stereoscopic images) and a second curvature (for two-dimensional images), allowing the system to adapt to different display modes and reduce power consumption when stereoscopic effect is not needed.
Solution Approach 2:
The patent implements parameter changes by varying the curvature parameter of the display surface. By changing the curvature from a first curvature to a second curvature, the system can switch between different display modes. This parameter change enables the display device to optimize performance for different image types without requiring additional components like shutters.
2Reliability
If a display device uses a parallax barrier to display stereoscopic images, then the viewer can see a stereoscopic image with naked eyes, but the number of pixels contributing to image display is reduced and high-definition images cannot be displayed

AI summary
To provide a display device that gives a viewer a strong stereoscopic effect or sense of depth or a natural stereoscopic effect or sense of depth in a two-dimensional image, a display device including a display portion having a curved surface is provided. The display portion may be bent in a horizontal direction or a vertical direction. Alternatively, the display portion may have a convex surface or a concave surface on a display surface side. The display device may include a frame portion. A display device including a frame portion and a display portion which has a display surface on a frame portion side, is located so as to be apart from the frame portion with a distance therebetween, and has a curved surface, in which the display portion overlaps with an opening of the frame portion, and an end portion of the display portion overlaps with the frame portion, is provided.
