Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, such as LED displays, face challenges in reducing the distance between LEDs to improve image fineness and display quality, due to the need for a certain interval to accommodate driving circuits.
Innovation Solution
A display panel design that includes a display module with a lens layer. The lens layer, comprising an array of convex lenses, refracts light emitted by pixel units, allowing for a reduced pixel distance in the display image without decreasing the pixel unit distance in the display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the distance between pixel units is reduced to improve image fineness, then the display quality is improved, but it becomes difficult to accommodate driving circuits
Solution Approach 1:
The patent divides the display into pixel units (physical LED components) and pixels (visual display elements). By segmenting the functional roles, multiple pixels can be generated from fewer pixel units through optical imaging, allowing driving circuits to be accommodated with larger pixel unit spacing while still achieving fine image quality through increased pixel density in the displayed image.
Solution Approach 2:
The patent introduces a lens layer as an intermediary between pixel units and the displayed image. The lens layer optically magnifies and projects the light from pixel units to create a higher density of pixels in the displayed image, thereby decoupling the physical spacing requirements of pixel units from the visual fineness requirements of the display.
2Manufacturing precision
If the pixel distance is reduced to increase pixel density, then the display quality is improved, but the pixel unit distance must also be reduced which increases manufacturing difficulty
Solution Approach 1:
The patent replaces the mechanical approach of physically spacing pixel units closer together with an optical approach using lens magnification. Instead of reducing pixel unit distance mechanically, the system uses optical imaging to create the effect of higher pixel density, making manufacturing easier while achieving the same visual result.
Solution Approach 2:
The patent changes the optical parameters of the system by introducing lenses with specific focal lengths and imaging distances. By adjusting the imaging distance and lens parameters, the system achieves pixel density multiplication without changing the physical spacing of pixel units, thereby simplifying manufacturing.
3Manufacturing precision
If the number of pixel units is increased to improve display quality, then the image fineness is improved, but the cost increases
Solution Approach 1:
The patent uses optical imaging to create multiple pixel copies in the displayed image from fewer pixel units. Each pixel unit's light output is optically projected and imaged to form multiple pixel elements in the final display, effectively copying the visual information without requiring proportional increases in the number of physical pixel units.
Solution Approach 2:
The patent makes each pixel unit serve multiple functions: it generates light that is then optically distributed to form multiple pixels in the displayed image. This multi-functionality allows fewer pixel units to achieve the display quality that would traditionally require many more individual pixel units, thereby reducing cost.

Function Achieved in This Case
The solution enhances the fineness of the displayed image by increasing the density of pixels in the display image, while maintaining the pixel unit density in the display module, thus improving display quality and cost control.
Implementation Method 1
The lens layer, comprising an array of convex lenses, refracts light emitted by pixel units, allowing for a reduced pixel distance in the display image without decreasing the pixel unit distance in the display module.

AI summary
A display panel includes a display module and a lens layer. The display module has a display region and includes a plurality of pixel units disposed in the display region and distributed in an array, each pixel unit is configured to emit light. The lens layer is disposed on a display side of the display module. Light emitted by the plurality pixel units passes through the lens layer to form a display image, and the display image includes a plurality of pixels distributed in an array. The number of pixel units included in a row of pixel units in a first direction is less than the number of pixels included in a row of pixels in the first direction. A first pixel distance is smaller than a first pixel unit distance.
