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.

Abstract: A display device is provided including a display panel. A pixel of the display panel includes a light emitting element, first through sixth transistors, and a capacitor. The first transistor is connected between a power line and the light emitting element and operates depending on a potential of a first node. The second transistor is connected between a data line and a second node. The capacitor is connected between the first node and the second node. The third transistor is connected between the first transistor and the first node. The fourth transistor is connected between the first node and a reference voltage line. The fifth transistor is connected between the second node and the reference voltage line. The sixth transistor is connected between the power line and the second node.

Abstract: A display panel includes sub-pixels each including a light-emitting element and a pixel circuit including a first transistor and a second transistor; a timing control unit to generate bias data based on first characteristic information of the first transistor, and generate correction data based on second characteristic information of the second transistor; and a data sensing driving unit configured to receive the bias data and the correction data, and output a bias voltage and a grayscale voltage to the pixel circuit. The pixel circuit includes the first transistor to output a driving current to the light-emitting element; a first driving circuit to control a magnitude of the driving current based on the bias voltage; and a second driving circuit including the second transistor and configured to control a pulse width of the driving current based on the grayscale voltage.

Abstract: A flexible display is disclosed. In one aspect, the display includes at least one first pattern including a plurality of display elements configured to display an image and extending in a first direction. The display device also includes at least one second pattern extending in a second direction and overlapping at least a portion of the first pattern. The second pattern has a curved shape in the first direction and the second direction crosses the first direction. The first and second patterns form at least one cavity region defining a space therebetween and the first and second patterns form a mesh structure.
