Display Device Reducing Color Break via Differential Subframe

The frame period is segmented into three subframe periods (first, second, and third subframe periods) to sequentially output different colors (red, green, blue). This segmentation allows each color to be displayed in its dedicated time slot, improving color reproduction accuracy while the sequential timing prevents color break by ensuring complete color separation.

The light source device operates in a periodic cycle, sequentially emitting red, green, and blue light in each frame period. This periodic action with controlled timing ensures that each color is output in its designated subframe period, achieving accurate color reproduction while the rhythmic cycling prevents color break through consistent temporal separation.

Pixel data with low gradation values (below the threshold) are extracted and excluded from the color reproduction process. By removing these problematic data points that cause color break, the system achieves better color accuracy while retaining the majority of valid image information, effectively filtering out only the harmful elements.

Different processing is applied to different regions of the pixel data based on their gradation values. High gradation pixel data undergoes normal color conversion and output, while low gradation pixel data is excluded from color reproduction. This local quality differentiation ensures that only suitable data contributes to color accuracy while maintaining overall image integrity.
