    Abstract: An electroluminescence display is provided. The electroluminescence display comprises data lines and gate lines intersecting each other and pixels arranged in a matrix, wherein each of subpixels of each pixel comprises: a first driver configured to drive a light-emitting element by using a first EM switching element, which switches the current path between a power supply line to which a pixel driving voltage is applied and the light-emitting element in response to a first light-emission control signal, and a first driving element connected between the first EM switching element and the light-emitting element; and a second driver configured to drive the light-emitting element by using a second EM switching element, which switches the current path between the power supply line and the light-emitting element in response to a second light-emission control signal, and a second driving element connected between the second EM switching element and the light-emitting element.

    Abstract: A display device is provided in which each subpixel includes a driving TFT, an organic light-emitting diode, and at least one switching TFT for driving the subpixel. At least one of the driving TFT and the switching TFT is formed as a double-gate TFT having a first gate node and a second gate node, and each subpixel comprises a compensation circuit that senses a threshold voltage of the double-gate TFT and applies the same to the first gate node or the second gate node of the double-gate TFT.

    Abstract: A display apparatus includes a liquid crystal display (LCD) panel and a backlight coupled to the LCD panel. The LCD apparatus is capable of being operated in a plurality of modes. The gradation values of the image data is adjusted in accordance with gradation ranges, each gradation range having an upper limit gradation value and a lower limit gradation value. The first converted image data is then scaled by applying a scaling factor, followed by adjustment of backlight brightness. The frame rate of the LCD apparatus is also adjusted to implement the operation mode.
