Display Panel Optical Lenses Reduce Eye Image Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in minimizing overlap between right-eye and left-eye images provided by a single display panel without increasing overall thickness, which affects image quality and device thickness.
Innovation Solution
A display apparatus design featuring a display panel with light-emitting devices, an encapsulation unit, a black matrix, and optical lenses, where the black matrix extends between light-emitting devices and optical lenses are positioned to separate the right-eye and left-eye images, reducing overlap and maintaining a slim device thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a single display panel is used to provide both right-eye and left-eye images, then device thickness is reduced, but image overlap occurs between the two eyes
Solution Approach 1:
The patent divides the display panel into multiple light-emitting device regions, with specific areas designated for right-eye images and left-eye images. This segmentation allows each eye to receive dedicated light from its corresponding light-emitting devices, preventing image overlap while maintaining a single thin display panel structure.
Solution Approach 2:
The patent implements local quality differentiation by assigning different functional characteristics to different regions of the display panel. Specifically, certain light-emitting devices are configured to emit light primarily for the right eye, while others are configured for the left eye, creating localized optical zones that prevent cross-contamination of images.
2Reliability
If optical lenses are added to separate right-eye and left-eye images, then image quality improves, but device thickness increases
Solution Approach 1:
The patent extracts the image separation function from traditional optical lenses and transfers it to the light-emitting device structure itself. By configuring specific light-emitting devices to emit light in specific directions toward specific eyes, the patent eliminates the need for additional lens components, thereby maintaining thin device profile while achieving effective image separation.
Solution Approach 2:
The patent replaces the mechanical optical lens system with an electronic/optical control system at the light-emitting device level. Instead of using physical lenses to separate images, the patent uses controlled light emission from specifically positioned and oriented light-emitting devices, substituting a mechanical optical solution with a more integrated electronic-optical approach.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively separates right-eye and left-eye images, enhancing image quality and reducing the overall thickness of the display apparatus without increasing the thickness of the device body.
Implementation Method 1
The optical lenses are disposed on the black matrix. Each of the optical lenses extends in the second direction. Each of the optical lenses overlaps at least two light-emitting devices adjacent in the first direction

AI summary
A display apparatus including a display panel and an eyepiece is provided. The eyepiece may include a right-eye lens corresponding to a right eye of a user and a left-eye lens corresponding to a left eye of the user. The display panel may provide a right-eye image through the right-eye lens and a left-eye image through the left-eye lens. The display panel may include an encapsulation structure covering light-emitting devices, a black matrix on the encapsulation structure, and optical lenses on the black matrix. The black matrix may extend in a first direction and a second direction perpendicular to the first direction between the light-emitting devices. Each of the optical lenses may extend in the second direction. Each of the optical lenses may overlap at least two light-emitting devices adjacent in the first direction and a portion of the black matrix disposed between the corresponding light-emitting devices. Thus, in the display apparatus, an overlap between a right-eye image and a left-eye image provided to the user by a single-display panel may be minimized or reduced.
