Electroluminescent Light Sources TRIZ Cases
- OLED Fabrication Using Thermal Transfer for Red and Green Emission Layers
A method transfers pre-formed red and green organic emission patterns to a display substrate using Joule heating from heat-generating elements.
- Anxiety-Adaptive Lighting System for Outdoor Safety
A lighting system uses physiological sensors to detect user anxiety and dynamically adjusts illumination levels.
- Switching Regulator Control Circuit for LED Dimming EMI Reduction
Ramping LED current via a programmable reference signal reduces electromagnetic interference and control loop overshoot during PWM dimming.
- Organic Light-Emitting Display Pixel Segmentation for External Light Transmittance
A segmented organic light-emitting display pixel structure separates emission and penetration zones to maximize external light transmittance.
- Adaptive LED Driver Power Regulation for Emergency Lighting
Closed-loop power feedback compensates for LED variations, ensuring 90-minute runtime without manual tuning.
- Multi-Layered Solid-State Light Emitter Structure
A multi-layered engineered structure uses alternating active and buffer layers to generate efficient light emission from solid-state emitters.
- LED Driver Switching Thermistor and Discharge Resistor for Power Efficiency
A light source driving apparatus uses a switch to connect thermistors and discharge resistors only during startup or power cut-off.
