  • Display apparatus and method of driving the same
    Patent number: 11990091
    Abstract: A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver provides a gate signal to the pixel. The data driver provides a data voltage to the pixel. The emission driver provides an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element which applies a driving current to the light emitting element, a storage capacitor connected to a control electrode of the driving switching element and a bias capacitor including a first electrode connected to the storage capacitor and a second electrode which receives a bias gate signal. A waveform of the bias gate signal varies based on an off ratio representing a ratio of an off period of the emission signal in a frame period.
