Abstract

The Local Color display technology utilizes a high refresh rate LCD open-cell without a color filter, and enables color adjustment through independent RGB backlight zones that are isolated by an Anti-Scatter Grid (ASG). Synchronized calibration between the open-cell and the backlight zones is achieved by aligning the backlight controller with the Vertical Clock Pulse (CPV) / Vertical Start Pulse (STV) signals in the open-cell gate driver, thereby determining the open-cell scan line position. After the synchronous calibration is completed, the backlight controller refreshes the corresponding RGB backlight zones whenever the open-cell scan line passes through them. The Local Color display technology can reduce the cost of open-cell by 20%, improve the resolution to 3x, improve the brightness to 8x, improve the color gamut to BT2020, and improve the grayscale to 32-bits.
