Abstract (en)
[origin: EP2012298A2] The present invention discloses methods and display drivers for pixel status detection of flat panel displays. The method includes the following steps of: providing scan data to the register; using the scan data to drive the pixel; detecting the pixel status to obtain status data; refreshing the register with the status data; and, comparing the scan data with the status data to determine whether the pixel is in abnormal status or not. Based on the aforementioned method, the pixel status could be real-time monitored.
