Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution display technologies, such as '8K' projection, require expensive hardware, making them unfeasible for mainstream market adoption due to high production costs.
Innovation Solution
A display equipment configuration using a display device, a backlight device, and lenticular lens arrays to refract light in a vertical direction, allowing multiple display elements to project pixels at different vertical heights, thereby improving display resolution without upgrading hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If 8K high-resolution projection technology is used, then display resolution is improved, but production cost and market price increase significantly
Solution Approach 1:
The patent divides the backlight into multiple independent light sources (first and second incident light sources) that can be controlled separately. This segmentation allows the system to achieve higher effective resolution by selectively activating different light sources for different pixel rows, avoiding the need for expensive 8K hardware while achieving similar display quality
Solution Approach 2:
The patent introduces a new dimension of control by using multiple backlight light sources positioned at different vertical locations to control different horizontal pixel rows. This dimensional approach to backlight control enables resolution enhancement without requiring proportionally expensive hardware upgrades
2Manufacturing precision
If multiple backlight light sources are used to control different pixel rows, then display resolution is enhanced, but device structure becomes more complex
Solution Approach 1:
Each backlight light source serves multiple functions: it provides illumination for specific pixel rows, acts as a controllable light source for resolution enhancement, and can be independently adjusted for brightness and timing. This multi-functionality reduces the need for additional specialized components, thereby limiting complexity growth
Solution Approach 2:
The patent controls display resolution and image quality by changing parameters of existing components (brightness, timing, and activation state of different backlight light sources) rather than adding complex hardware. This parameter-based control approach enhances resolution while maintaining relatively simple device structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances display performance by doubling the resolution in both horizontal and vertical directions, achieving high-resolution images with lower-level hardware, thus reducing production costs.
Implementation Method 1
After the first incident light and the second incident light sequentially are refracted by the plurality of first lenticular lens and the plurality of second lenticular lens, the first incident light and the second incident light are projected onto positions at different vertical heights on the display elements
Data Source
AI summary
Display equipment includes a display device, a backlight device, a first cylindrical lens array and a second cylindrical lens array. The display device includes multiple display units. At least three adjacent display elements are used to display at least one pixel in an image. The backlight device is configured to generate multiple first incident light and multiple second incident light. The first cylindrical lens array and the second cylindrical lens array are configured to refract the first incident light and the second incident light. After the first cylindrical lens array and the second cylindrical lens array refract the first incident light and the second incident light time-sequentially, the light will be projected at the positions with different vertical heights on the display units.
