Liquid Crystal Display Light Shielding Film Narrow Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices face issues with light leakage and insufficient spacing between panels due to the presence of a light shielding plate, which also requires adhesive bonding.
Innovation Solution
Incorporation of a light shielding film on the side surfaces of adjacent liquid crystal display panels to block light from a back light, allowing for narrow spacing and adhesive-free assembly, supplemented by a joint filler or light shield to further suppress light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light shielding plate is disposed in the gap between adjacent liquid crystal display panels, then light leakage is suppressed, but the spacing between panels cannot be sufficiently narrowed and adhesive bonding is required
Solution Approach 1:
The patent replaces the rigid light shielding plate with a flexible light shielding film that is formed directly on the side surface of the liquid crystal display panel. This film can be made extremely thin and flexible, allowing the panels to be positioned very close together without the need for a bulky separate shielding plate, thus resolving the contradiction between light leakage suppression and narrow spacing.
Solution Approach 2:
The light shielding function is merged with the panel structure itself by forming the light shielding film directly on the side surface of the panel. This eliminates the need for a separate light shielding plate and adhesive bonding, allowing the panels to be adhered directly to each other with minimal spacing.
2Object-affected harmful factors
If a light shielding plate is disposed in the gap between adjacent liquid crystal display panels, then light leakage is suppressed, but the assembly process becomes more complex requiring adhesive bonding
Solution Approach 1:
The light shielding function is merged with the panel structure itself by forming the light shielding film directly on the side surface of the panel. This eliminates the need for a separate light shielding plate and adhesive bonding, allowing the panels to be adhered directly to each other with minimal spacing.
Solution Approach 2:
The invention extracts the light shielding function from a separate component (light shielding plate) and integrates it into the panel structure itself through the light shielding film. This simplifies the overall assembly by reducing the number of separate components and eliminating the need for adhesive bonding between panels and shielding plates.
3Area of stationary object
If multiple liquid crystal display panels are arranged to configure one screen, then display area is increased, but light leakage occurs at the joint portions
Solution Approach 1:
The patent uses a flexible light shielding film formed on the side surfaces of the panels to block light leakage at the joint portions between adjacent panels. This allows multiple panels to be arranged to create a larger display area while effectively suppressing light leakage at the boundaries between panels.

AI summary
A liquid crystal display device includes a juxtaposed plurality of liquid crystal display panels, and a back light that emits light on the plurality of liquid crystal display panels. Each of the plurality of liquid crystal display panels includes, on a side surface opposing a side surface of the liquid crystal display panel adjacent thereto, a light shielding film that blocks the light from the back light.
