LED Display Cover Curing Process via Glue Barrier

Solution Overview

Problem

Existing display screen covers for small-pitch LED screens are fragile, difficult to manufacture, and provide limited protection to LED lamp beads, often damaging them during assembly and offering inadequate structural strength.

Innovation Solution

A manufacturing process involving a glue barrier and press plate to cure a display screen cover directly onto a lamp panel, ensuring complete coverage and enhanced structural strength by filling gaps between LED lamp beads with glue, thereby protecting them from damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cover is attached to protect LED lamp beads, then protection effect is improved, but the cover structure becomes more fragile due to small holes for densely distributed LED lamp beads

Engineering Contradiction:

Improveprotection effectVSAvoidcover structure strength

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent merges the cover and LED lamp beads into a single integrated structure by injecting glue through holes in the cover to fill gaps between LED lamp beads, forming a unified whole that enhances structural strength while maintaining protection function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary action by injecting glue through holes in the cover before final assembly, filling gaps between LED lamp beads in advance to strengthen the cover structure and prevent future damage

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If holes are formed in the cover to allow LED lamp beads to penetrate, then LED lamp beads can be exposed, but the cover becomes more fragile and protection effect is limited

Engineering Contradiction:

ImproveLED lamp bead exposureVSAvoidcover structure strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The patent merges the cover and LED lamp beads into a single integrated structure by injecting glue through holes in the cover to fill gaps between LED lamp beads, forming a unified whole that enhances structural strength while maintaining protection function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent converts the harmful effect of holes weakening the cover into a benefit by using the same holes to inject glue that fills gaps between LED lamp beads, thereby strengthening the cover structure and improving protection effect

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If existing manufacturing processes are used, then production can proceed, but the manufacturing process is difficult and cost is high

Engineering Contradiction:

Improveproduction efficiencyVSAvoidmanufacturing difficulty

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The patent merges multiple manufacturing steps into a single integrated process by injecting glue through holes in the cover to fill gaps between LED lamp beads and form the cover structure simultaneously, simplifying the manufacturing process and reducing cost

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent performs preliminary action by injecting glue through holes in the cover before final assembly, filling gaps between LED lamp beads in advance to strengthen the cover structure and simplify subsequent manufacturing steps

Inventive Principle:

Principle #10Preliminary action

AI summary

The invention discloses a manufacturing process of a display screen cover, and a display screen. The manufacturing process includes the following steps: S1, providing a lamp panel provided with LED lamp beads; S2, arranging a glue barrier; S3, filling the hollow region of the glue barrier with glue I, and covering the LED lamp beads with the glue I; S4, providing a press plate; S5, curing the glue I; and S6, removing the press plate and the glue barrier. The cover does not need to be additionally assembled on the lamp panel, so that the lamp beads are protected against damage from the cover, and the yield of display screens is increased; and gaps between the lamp beads are completely filled with the cover, so that the lamp beads are fully protected.
