Solution Overview

Problem

Conventional LED displays experience a gap and resulting black lines when two screens are angularly connected, preventing a seamless display effect.

Innovation Solution

A corner transition module with a module case, LED circuit board, and curved face cover is designed to connect LED displays at angles between 90° and 180°, ensuring consistent LED pixel spacing and using specific geometric formulas to determine the dimensions of the module case and curved face cover for a seamless arc transition.

1Shape

If conventional planar LED display modules are angularly connected, then the display can be assembled in a rectangular or square configuration, but a gap and black line will be formed at the connecting corner between screens

Engineering Contradiction:

Improvedisplay configurationVSAvoidseamless display effect

Core Design Contradiction:

ShapeVSManufacturing precision

Solution Approach 1:

The patent applies curvature by designing the corner transition module with an arc-shaped cross-section. The module case and curved face cover form a curved structure that bridges the gap between two planar display screens connected at an angle. This curved geometry allows the LED light-emitting array to follow an arc path, eliminating the linear gap that would otherwise appear at the corner connection point and achieving a seamless display effect.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Manufacturing precision

If a corner transition module with arc-shaped cross-section is used, then a seamless display effect is achieved, but the structural complexity and manufacturing difficulty increase

Engineering Contradiction:

Improveseamless display effectVSAvoidmodule structure

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The corner transition module is divided into distinct functional components: a module case with arc-shaped cross-section, a curved face cover, and a LED circuit board. This segmentation allows each component to be manufactured separately using standard processes, then assembled together. The modular design reduces the complexity of manufacturing the entire curved structure in one piece while maintaining the seamless display effect.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The corner transition module is designed to serve multiple functions: it provides the curved geometric transition for seamless display, houses the LED light-emitting array, contains the control circuitry, and structurally connects two display screens at an angle. By integrating these functions into a single module, the overall system complexity is reduced compared to using separate components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A corner transition module includes a module case, a LED PCB board, a curved face cover. The LED PCB board is set in the space defined between the module case and the curved face cover. The module case is mounted on a LED installing position. A plurality of LED installing holes is provided on the curved face cover to couple with the LEDs on the LED PCB board. The corner transition module solves the problem that two flat display screens being angularly connected in resulting in a display defects with a black line at the connecting corner. With the corner transition module, the non-planar screens are seamlessly connected to form a perfect full-screen display effect in high-performance graphics display without any black line.
