Latest Patents
One of Janghoon Song's latest patents is an organic light emitting display and method for controlling emission thereof. This innovation discusses an organic light emitting display that can effectively reduce flicker while also minimizing power consumption. In a low-power operation mode, at least one holding frame is placed between writing frames where image data is written. The output of the source driver is enabled during the writing frames and disabled during the holding frames. The emission driver is controlled during the holding frames to increase the toggle frequency of the emission signal to be higher than or equal to N times the frame frequency, where N is a positive integer greater than or equal to 2. This driving method significantly reduces the perceived flicker.
Another notable patent is the organic light emitting diode display device. This device operates in a black mode where the threshold voltage of a driving TFT does not need to be accurately sensed. A low voltage value of zero or less is continuously supplied to a data line during the initialization, sampling, and programming periods in a pixel. Consequently, when the pixel is driven in the black mode, a reference voltage and a data voltage with different values are not alternately supplied to the data line, which minimizes power consumption.
