A digital time‐modulation pixel memory circuit on glass substrate has been designed and verified in a 3‐μm low temperature poly‐silicon (LTPS) technology. The proposed circuit can generate 4‐bit digital codes and the corresponding inversion data by time‐modulation technique to refresh the static image without activating the data driver circuit. Therefore, the data driver of liquid crystal display (LCD) panel is not required to provide the image data of the frame by the proposed circuit while the LCD panel operates in the still mode. The power consumption from data driver can be further reduced in the LCD panel.
