Illuminated Signs TRIZ Cases
- LED Matrix Lighting Device Using Segmented Circuit Boards
Segmented elongated circuit boards with electrical passageways provide even lighting across large areas while reducing material usage and installation time.
- Optical Element Internal Reflector Sunlight Back Reflection
An optical element uses an internal reflector to redirect sunlight via total reflection.
- Letter and Number Decorative Panel Slot Insertion Assembly
Segmented side plates with pre-formed insertion plates engage base plate slots to eliminate gluing delays and ensure consistent assembly quality.
- Backlight Unit Mold Frame Inclined Surface Edge Luminance
Inclined mold frame surface redirects light to backlight unit edges, resolving edge luminance uniformity issues.
- Pivoting Clamping Bridge for Poster Tensioning
A pivoting clamping bridge with a tension spring compensates for flexible carrier stretching by rotating the clamping arm.
- Optical Sheet Protrusions Brightness View Angle Trade-off
Segmented flat and prism regions resolve the brightness versus view angle contradiction by combining diffusion and condensation functions in one component.
- Elastic Member Mounting Device for Easy Panel Replacement
A plate-like member mounting device uses elastic members that deform under thrust to support panels securely.
- Modular Illuminated Sign Components with Integrated Connecting Bars
Segmented sign components with universal connecting bars resolve the trade-off between custom message flexibility and manufacturing cost.
- Removable Light Source Unit for LCD Backlight Maintenance
A removable light source unit couples to a lower receptacle sidewall for direct thermal conduction.
- Backlight Unit Frame Width Reduction via Extraction and Segmentation
A backlight unit design compresses frame width by removing the traditional case and segmenting the support structure into resin and metal components.
- Reflective Cover Segment Notch Asymmetry for Display Light Leakage
Asymmetric notch positioning in display device segment structures prevents light leakage and ensures uniform emission across character segments.
- LCD Support Main Curved Protrusion Prevents Panel Friction
Curved support main protrusions maintain liquid crystal panel spacing, preventing friction and scratches caused by vibration in thin display devices.
- LED Illuminated Sign Frame with Integrated Heat Dissipation
Integrated support panels dissipate heat from LED emitters while protecting electronic drivers within the sign assembly.
- Selective Reflective Layer for Array Substrate Light Utilization
A selective reflective layer on an array substrate reflects specific wavelengths while transmitting others to reuse light within the display stack.
- Back Light Unit With Segmented Diffusing Plate For Uniformity
Segmenting the diffusing plate into regions at varying distances from LEDs resolves the trade-off between backlight thickness and light uniformity.
- Retroreflective Sheeting Halftone Ink Pattern Reflectivity
Discrete halftone ink dots create light-transmissive openings that reduce absorption and scattering, eliminating the need for a clear topcoat layer.
