Multi-Area Display Panel Viewing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to independently control the viewing angle of images in different areas of the display, which is necessary for applications such as vehicle displays where specific viewing modes are required for different user positions.
Innovation Solution
A display device with a display panel divided into multiple areas, each driven by a panel driver that provides mode control signals to pixels, allowing each area to be independently operated in either a public mode with a wide viewing angle or a private mode with a narrower viewing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device uses a single viewing angle mode for the entire display area, then the device complexity is reduced, but the adaptability to different user positions deteriorates
Solution Approach 1:
The display panel is divided into multiple areas (first area and second area) that can be independently controlled. Each area can be driven in different viewing angle modes (public mode with wide viewing angle or private mode with narrow viewing angle) based on user position, allowing the system to adapt to different viewing scenarios without requiring a completely complex redesign of the entire display system
Solution Approach 2:
Different areas of the display panel are assigned different viewing angle characteristics. The first area can display images with a first viewing angle while the second area displays images with a second viewing angle. This local differentiation allows each area to be optimized for specific user positions or viewing scenarios, improving overall adaptability without requiring the entire display to be redesigned
2Adaptability or versatility
If the display device provides multiple viewing angle modes for different areas, then the adaptability to different user positions is improved, but the device complexity increases
Solution Approach 1:
The display system dynamically switches between different viewing angle modes (public mode and private mode) for different areas based on real-time detection of user position. The panel driver receives detection signals and dynamically adjusts the driving modes of different areas, allowing the system to adapt to changing viewing scenarios without requiring manual configuration or complex pre-programming
Solution Approach 2:
The system incorporates user position detection that provides feedback to the panel driver. Based on this feedback, the panel driver automatically determines which viewing angle mode should be applied to which area, enabling intelligent and adaptive control without requiring complex user interaction or manual setting mechanisms

AI summary
A display device includes: a display panel including a first area and a second area; and a panel driver configured to drive the display panel, to provide a first mode control signal to pixels in the first area, and to provide a second mode control signal to pixels in the second area, wherein the first area is configured to be driven in a first mode to display an image having a first viewing angle or a second mode to display an image having a second viewing angle narrower than the first viewing angle based on the first mode control signal, and wherein the second area is configured to be driven in the first mode or the second mode based on the second mode control signal.
