Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional naked eye 3D display technologies face limitations such as small observation range, poor picture continuity, and reduced display brightness due to the use of lenticular lens gratings and slit gratings, which restrict their commercial application and effectiveness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenticular lens gratings and slit gratings are used for naked eye 3D display, then 3D display function is achieved, but observation range is limited and picture continuity is poor
Solution Approach 1:
The patent extracts and removes the lenticular lens grating and slit grating components from the display system. Instead of using these optical gratings to achieve 3D effects, the invention directly controls light-emitting elements to emit light in different directions, thereby eliminating the limitations of small observation range and poor picture continuity associated with traditional grating-based approaches.
Solution Approach 2:
The patent replaces the mechanical/optical grating system with an electrical control system. By applying voltages to electrode pillars, the light-emitting elements are controlled to tilt and emit light in specific directions, substituting the passive optical grating mechanism with an active electrical control mechanism that achieves better observation range and picture continuity.
2Adaptability or versatility
If lenticular lens gratings are used, then 3D display is enabled, but display brightness is reduced
Solution Approach 1:
The patent removes the lenticular lens grating component that causes light loss and reduced brightness. By directly controlling light-emitting elements to emit light in different directions without passing through gratings, the system eliminates the light absorption and scattering issues that reduce display brightness in traditional 3D displays.
Solution Approach 2:
The patent implements dynamic control of light-emitting element orientation by applying voltages to electrode pillars. This allows real-time adjustment of light emission directions to match viewer positions, ensuring that light reaches the intended eyes efficiently without being lost to the grating structure, thereby maintaining high brightness while enabling 3D display.
3Adaptability or versatility
If electrostatic voltages are applied to control elastic electrode pillars, then viewing angles and brightness are improved, but device complexity increases
Solution Approach 1:
The patent makes the electrode pillars serve multiple functions: they act as both structural support for the light-emitting elements and as electrostatic actuators for controlling the tilt angle. This multi-functionality reduces the need for separate control mechanisms, thereby managing device complexity while achieving improved viewing angles and brightness through voltage-controlled elastic deformation.
