Title:
MULTI-ROW SCANNING LED GRAYSCALE SWITCHING DISPLAY METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/147170
Kind Code:
A1
Abstract:
A multi-row scanning LED grayscale switching display method. When displaying a relatively high grayscale, periodically scrambling display, causing an illumination cycle to be distributed as uniformly as possible in an image frame; and when displaying a relatively low grayscale, performing grayscale merging, and by means of a grayscale compensation method, making up for grayscale loss caused by analog circuit response time. This makes it possible, when a number of row scans is relatively high, to continue to maintain a relatively high refresh rate and grayscale level, and in a low-grayscale display situation, resolves problems including low-grayscale pitting, low-grayscale darkening and relatively poor low-grayscale linearity, realizing improved image display results.
