Solution Overview
Problem
Conventional display modules with frames visible when combined, affect image quality due to frame visibility and blurred magnified images in the rim area.
Innovation Solution
A frameless display module with a light transmissive layer that magnifies images from sections with higher pixel density, reducing frame visibility and maintaining image quality by distributing display pixels differently across sections and using a light transmissive layer to create a seamless combined image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the image in the rim area is magnified to reduce frame visibility, then the frame affect is reduced, but the image resolution becomes bad and blurred
Solution Approach 1:
The patent applies local quality by dividing the display area into a first area (central region) and a second area (rim area), with different pixel densities in each region. The second area has higher pixel density specifically to maintain image quality after magnification, while the first area uses lower pixel density to reduce overall complexity. This localized differentiation resolves the contradiction between frame visibility reduction and image resolution maintenance.
Solution Approach 2:
The patent changes the parameter of pixel density distribution across different areas of the display. By increasing pixel density in the second area (rim area) where magnification occurs, the system maintains adequate image resolution even after the magnification process. This parameter change allows the rim area to be magnified for frame coverage while preserving acceptable image quality.
2Ease of manufacture
If uniform pixel density is used across the display, then the manufacturing is simpler, but the magnified rim area image quality deteriorates
Solution Approach 1:
Instead of uniform pixel density, the patent implements local quality variation by creating a first area with lower pixel density and a second area with higher pixel density. The second area's elevated pixel density specifically addresses the quality degradation that occurs during magnification of the rim area, while the first area maintains simpler construction with lower density.
3Area of stationary object
If multiple displays are combined to create a bigger picture, then the display area is increased, but the frames become visible and cross the combined image
Solution Approach 1:
The patent segments the display into distinct functional areas: a first area for central content display and a second area (rim area) specifically designed for magnification. This segmentation allows the rim area to be enlarged through magnification to cover and hide the frames between adjacent displays, while the central area maintains normal display function.
Solution Approach 2:
The patent applies dimensionality change by magnifying the second area (rim area) in the visual dimension. This magnification enlarges the rim area's contribution to the final image, allowing it to extend into regions that cover the frames between adjacent displays. The dimensional transformation of the rim area enables frame coverage without affecting the central display content.

Function Achieved in This Case
The solution effectively hides the frame and maintains good image quality by varying pixel density and using a light transmissive layer to magnify images, creating a seamless and high-quality combined display.
Implementation Method 1
The light transmissive layer magnifies the first image provided by the display layer, transmitting from the second surface to the first surface and formed a second image

AI summary
A display module including display layer and light transmissive layer is provided. The display layer includes display pixels, the display pixels are distributed in first section and second section to display a first image, and the density of the display pixels in the second section is higher than the density of the display pixel in the first section. The light transmissive layer has first surface and second surface, wherein the second surface is facing the display layer. The light transmissive layer enlarges the first image provided by the display layer onto the first surface to form second picture, wherein the image from the second section is transmitted to the boarder area through the light transmissive layer. A display device is also provided.
