Abstract: A display device includes a display panel including a pixel including switching elements of a first type and a second type different from the first type, a gate driver for generating a gate signal based on a gate clock signal and providing the gate signal to the display panel, a data driver for providing data voltage to the display panel, an emission controller for providing an emission controlling signal to the display panel, and a driving controller for generating control signals for controlling the gate and data drivers, and the emission controller. In a low-frequency driving mode, the display panel operates in a writing frame for writing data in the pixel and in a holding frame for holding the data written in the pixel, and the driving controller provides the gate driver with a gate clock signal having a direct current (DC) voltage during the holding frame.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel comprising a switching element of a first type and a switching element of a second type different from the first type. The gate driver is configured to generate a gate signal based on a vertical start signal and a gate clock signal and output the gate signal to the display panel. The data driver is configured to output a data voltage to the display panel. The emission driver is configured to output an emission to the display panel. A driving frequency of the display panel is varied according to an input image. The gate clock signal has an active duration having a varied length according to the driving frequency.

Abstract: A display device includes a display panel and a display panel driver. The display panel includes a pixel having a switching element of a first type and a switching element of a second type different from the first type. The display panel driver drives the display panel. In a first mode, the display panel driver drives the switching element of the first type and the switching element of the second type with a high driving frequency. In a second mode, the display panel driver drives the switching element of the first type with the high driving frequency and the switching element of the second type with low driving frequency which is lower than the high driving frequency. In a third mode, the display panel driver drives the switching element of the first type and the switching element of the second type with the low driving frequency.
