Abstract: A pixel includes first and second subpixels. The first subpixel includes a first light emitting element, a first transistor configured to drive the first light emitting element, a second transistor configured to apply a data voltage to the first transistor in response to a first write gate signal and a fifth transistor configured to apply a power supply voltage to the first transistor in response to an emission signal. The second subpixel includes a second light emitting element having a viewing angle different from the first light emitting element, a sixth transistor configured to drive the second light emitting element, a seventh transistor configured to apply the data voltage to the sixth transistor in response to a second write gate signal different from the first write gate signal and a tenth transistor configured to apply the power supply voltage to the sixth transistor in response to the emission signal.

Abstract: A display apparatus includes an image data receiver receiving image data of an image to be displayed. A driving mode determining controller receives anomalous trichromat data of a user, determines a driving mode as either a general driving mode or an anomalous trichromat correction driving mode, and outputs a driving mode signal indicative of the determination. A correction mode requirement luminance calculator calculates a correction mode requirement luminance for an image output for the user. A backlight boosting determination controller determines a level of boosting light emitted from a backlight, and outputs a boosting determine signal. An image data converter converts image data corresponding to the anomalous trichromat data of the user and the correction mode requirement luminance, and outputs a data signal corresponding to correction image data. The backlight emits light having an intensity corresponding to signals. A pixel transmits light according to the data signal.

Abstract: Provided is a data driver including a digital to analog converter configured to convert image signal data into a plurality of data voltages, and an output buffer unit including a plurality of channels for outputting the plurality of data voltages. The output buffer unit includes a plurality of output blocks. Each output block includes one or more channels. Data voltages outputted from a first output block among the plurality of output blocks are delayed with a first time difference. Data voltages outputted from a second output block among the plurality of output blocks are delayed with a second time difference which is different from the first time difference.
