摘要: In a display device, the anode voltage of an organic light emitting element is periodically reset. The control terminal of a driving transistor is periodically reset, and an input data voltage is connected to the control terminal through an input terminal and an output terminal of the driving transistor. As a result, good control over the displayed luminance is achieved. Other features are also provided.

摘要: A liquid crystal display (LCD) apparatus includes a first substrate, a second substrate, a liquid crystal layer and a backlight assembly. The first substrate includes a display part and a sensor part. The sensor part is disposed in a peripheral area of the display part and senses external light. The second substrate is disposed opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. The backlight assembly is disposed adjacent to the second substrate to expose the first substrate and to provide light. A light detecting function of the sensor part may be increased, so that the backlight may be used effectively and the power consumption of the display apparatus may be reduced.

摘要: A display device includes a light emitting element, a capacitor, a driving transistor, and first to third switching units. The capacitor is connected between a first node and a second node. The driving transistor has an input terminal connected with a first voltage, an output terminal, and a control terminal connected with the second node, and it outputs a driving current to the light emitting element. The first switching unit selects and connects one of a data voltage and a second voltage to the first node. The second switching unit switches a connection between the second voltage and the second node. The third switching unit selects and connects one of the second node and the light emitting element to the output terminal of the driving transistor.
