AI Technical Summary
Technical Problem
Existing display devices are prone to signal distortion during signal transmission, which leads to a decrease in image quality.
Method used
Image data is scrambled using a timing controller. Output data is determined by calculating the count of unbalanced patterns to reduce signal distortion. The system includes a scrambler, a pattern detection unit, and an output data determination unit. Dynamic scrambling mode is used to generate data with minimal signal distortion.
Benefits of technology
It effectively reduces signal distortion, prevents image quality degradation, and improves the image display effect of the display device.
