Abstract:
1. A light emitting display apparatus, comprising: a data controller; a pixel portion comprising a plurality of pixels for emitting light in response to a data signal and a scan signal, wherein each pixel comprises: a data driver configured to generate and transmit the data signal to the pixel portion; a scan driver configured to generate and transmit the scan signal to the pixel portion; and a timing controller configured to selectively receive video data and to control the data driver and the scan driver; wherein the data controller is configured to receive the diverted current from each of the pixels and to determine whether the sum of the diverted currents flowing through at least two pixels indicates that at least one of the pixels is receiving an overcurrent, wherein the overcurrent exceeds a maximum rated current for the pixel, wherein the data controller is further configured to control a switching portion so as to prevent the video data from being transmitted to the timing controller if the sum of the diverted currents flowing through at least two pixels indicates that at least one of the pixels is receiving an overcurrent, wherein the data controller further comprises:
