Angle-Compensated Display Panel Control for Stable 3D Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to maintain high display quality when outputting three-dimensional images, particularly due to changes in region angles affecting luminance and color coordinates, which degrade the image output.
Innovation Solution
A display device with a display panel comprising first and second display regions, controlled by a driving controller that adjusts luminance and color coordinates based on angle control signals, using luminance and color coordinate compensation data generated from look-up tables to maintain optimal display quality during angle changes.

Engineering Contradiction Analysis
1Adaptability or versatility
If the region angle of the display panel is changed to output three-dimensional images, then the three-dimensional image output capability is improved, but the display quality deteriorates due to luminance and color coordinate changes
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting luminance and color coordinates based on the region angle. The driving controller modifies display parameters (luminance and color coordinates) in response to angle changes, ensuring that display quality is maintained across different viewing angles while enabling three-dimensional image output.
Solution Approach 2:
The patent implements feedback control by using the region angle information to adjust display parameters. The driving controller receives angle information and automatically compensates for luminance and color coordinate changes, creating a closed-loop system that maintains display quality despite angle variations.
2Manufacturing precision
If the luminance and color coordinates are adjusted dynamically, then the display quality is improved, but the device complexity increases
Solution Approach 1:
The driving controller performs multiple functions: it controls the display panel, processes angle information, and adjusts luminance and color coordinates. By integrating these functions into a single controller, the patent avoids adding separate complex subsystems while still achieving dynamic display quality adjustment.
Solution Approach 2:
The patent uses pre-stored luminance and color coordinate compensation data corresponding to different region angles. This preliminary preparation of compensation data allows the driving controller to quickly adjust display parameters without complex real-time calculations, reducing control system complexity.

AI summary
An electronic device includes: a beam splitter, a display device configured to output an image to the beam splitter, and an angle controller configured to control an angle of a display panel included in the display device. The display device includes the display panel including first and second display regions, a data driver configured to apply a data voltage based on a data signal to the display panel, a gate driver configured to output a gate signal to the display panel and a driving controller configured to output the data signal to the data driver. A region angle, which is an angle between the first display region and the second display region, is changed based on an angle control signal. The driving controller changes a setting luminance of at least one of the first display region and the second display region based on the angle control signal.
