An FPGA-based MiniLED zonal backlight system on Gowin. Achieves real-time 1280x800@60Hz video processing with 360-zone luminance control. Implements multiple local dimming algorithms with ambient-light adaptive tuning.
An open-source tool for semiconductor band-structure calculation and visualization. Turns abstract equations into interactive plots for faster parameter validation in learning and prototyping.
A personal media collection system for books, movies, series, and music. Built with Astro 5 and a zero-database JSON architecture to keep deployment lightweight and data portable.
Synthetic Metals, 2026 (IF = 4.6)
Investigates OLED light-extraction and color-shift tradeoffs using an external quasi-periodic convex-sphere film. Demonstrates enhanced extraction with low color shift and near-Lambertian distribution.
Explores TFSI ionic-liquid modified PEDOT:PSS to improve OLED hole injection and device stability. Currently focused on process tuning and repeatability validation.
