摘要: A digital time-modulation pixel memory circuit on glass substrate has been designed and verified for a 3-mu m low-temperature polysilicon (LTPS) technology. From the experimental results, the proposed circuit can generate 4-bit digital codes and the corresponding inversion data with a time-modulation technique. While the liquid-crystal-display (LCD) panel operates in the still mode, which means the same image is displayed on the panel, a data driver for an LCD panel is not required to provide the image data of the frame by the proposed pixel memory circuit. This pixel memory circuit can store the frame data and generate its corresponding inversion data to refresh a static image without activating the data driver circuit. Therefore, the power consumption of a data driver can be reduced in the LCD panel.
