Auto-stereoscopic Display Panel Timing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto-stereoscopic 3D displays require additional software processing to generate interlaced images, reducing efficiency and limiting hardware compatibility, as they need external hosts with specific software to display stereoscopic images.
Innovation Solution
The display panel is driven by gate drivers corresponding to odd-column and even-column pixels, with different driving timings for each, allowing direct generation of stereoscopic images without software synthesis, using a timing controller, gate drivers, and a source driver to coordinate the display of left-eye and right-eye images through a barrier unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If software processing is used to generate interlaced images for auto-stereoscopic 3D display, then stereoscopic images can be displayed, but display efficiency is reduced and hardware compatibility is limited
Solution Approach 1:
The display panel is designed with self-service capability to directly generate interlaced images for auto-stereoscopic 3D display without requiring external software processing. The panel includes a first pixel array for displaying left-eye images and a second pixel array for displaying right-eye images, with each pixel array having independent control circuits that can independently control the display timing and content of each eye's image, enabling the display device to autonomously produce the required interlaced image format.
Solution Approach 2:
The pixel array is segmented into distinct first and second pixel arrays, where the first pixel array is dedicated to displaying left-eye images and the second pixel array is dedicated to displaying right-eye images. This segmentation allows independent control and timing for each eye's image data, eliminating the need for software-based interlacing while maintaining hardware compatibility across different systems.
2Adaptability or versatility
If software processing is installed in the external host to display stereoscopic images, then 3D images can be displayed on the auto-stereoscopic 3D display, but compatibility between the display and host is restricted
Solution Approach 1:
The display panel is designed with self-service capability to directly generate interlaced images for auto-stereoscopic 3D display without requiring external software processing. The panel includes a first pixel array for displaying left-eye images and a second pixel array for displaying right-eye images, with each pixel array having independent control circuits that can independently control the display timing and content of each eye's image, enabling the display device to autonomously produce the required interlaced image format.
Solution Approach 2:
The software processing function for generating interlaced images is extracted from the external host system and transferred to the display panel itself. By embedding the interlacing capability directly in the hardware of the display panel, the invention removes the dependency on host software, thereby expanding compatibility to work with any standard host device without requiring specific software installations.
3Productivity
If gate drivers respectively corresponding to odd-column and even-column pixels are used, then stereoscopic images can be displayed without software synthesis, but the display module complexity increases
Solution Approach 1:
The pixel array is segmented into distinct first and second pixel arrays, where the first pixel array is dedicated to displaying left-eye images and the second pixel array is dedicated to displaying right-eye images. This segmentation allows independent control and timing for each eye's image data, eliminating the need for software-based interlacing while maintaining hardware compatibility across different systems.
Solution Approach 2:
The invention combines the functions of multiple gate drivers into a unified control structure that manages both odd-column and even-column pixels through coordinated timing signals. By merging the control functions and using a standardized interface, the complexity is managed systematically while maintaining the benefits of independent pixel control for efficient stereoscopic image display.

Function Achieved in This Case
This approach eliminates the need for software synthesis, enhancing hardware compatibility and display efficiency by directly generating stereoscopic images on the display panel, improving the viewing experience and compatibility with external hosts.
Implementation Method 1
an image presented to a viewer's left and right eyes is vertically cut in unit of pixel columns... When the new image is displayed, a parallax barrier is added in front of the new image. Through the shielding effect of parallel grating strips, the left eye and the right eye can respectively see a left-eye image and a right-eye image in the re-arranged image, so that a stereoscopic image can be perceived by the viewer's brain.

AI summary
An auto-stereoscopic three-dimensional (3D) display including a display module and a driving module is provided. The display module includes a display panel and a barrier unit. The display panel has odd-column pixels and even-column pixels. The barrier unit coordinates with a left-eye image and a right-eye image displayed by the display panel to switch vertically and alternatively arranged slits and barriers, so as to produce a stereoscopic image in a viewer's eyes through parallax. The driving module provides left-eye image data and right-eye image data to drive the display module. The driving module drives the odd-column and even-column pixels respectively according to different driving timings, so as to respectively and sequentially enables the odd-column and even-column pixels during a plurality of corresponding frame periods to receive the left-eye image data and the right-eye image data and allow the display panel to display the left-eye and right-eye images.
