    Abstract: A display device determines a target temperature based on an average luminance of each of the panel blocks, calculates a temperature change amount of each of the panel blocks by multiplying a difference between the target temperature and a previous prediction temperature of each of the panel blocks determined before a reference period by a block temperature coefficient of the panel blocks, and calculates a current prediction temperature of each of the panel blocks by adding the temperature change amount of each of the panel blocks to the previous prediction temperature of each of the panel blocks, the panel blocks include a first panel block and second panel blocks adjacent to the first panel block, and the block temperature coefficient of the first panel block is determined based on the target temperature of the first panel block and the target temperature of each of the second panel blocks.

    Abstract: A display apparatus includes pixels, each of the pixels including a light-emitting diode, a first transistor connected to a driving voltage line and the light-emitting diode, a second transistor connected to the first transistor and the light-emitting diode, a third transistor connected to the second transistor and a first initialization voltage line, and a fourth transistor connected to the light-emitting diode and a second initialization voltage line. During a frame, each of the pixels operates in a first scan period and a second scan period. The first scan period includes a write-period in which a data signal is supplied and a first emission period in which the pixel is configured to emit light at a brightness corresponding to the data signal.

    Abstract: A display device includes a display panel, a plurality of sensors, a signal control unit, and a backlight unit. A plurality of dimming regions is defined in the display panel. The signal control unit determines a plurality of representative luminance values corresponding to the plurality of dimming regions based on image data signals received from an external device and illuminance values of an external light measured by the plurality of sensors. The backlight unit provides lights having the representative luminance values to the display panel.

    Abstract: A display system includes a display apparatus and a pivot performing part. The display apparatus includes a display panel configured to display an image and including a gate line and a data line, a gate driving part configured to output a gate signal to the gate line, and a data driving part configured to output a data signal to the data line. The pivot performing part is configured to receive, from the display apparatus, a pivot request data for performing a pivot function which rotates the image, and is to perform the pivot function on image data of the image in response to the pivot request data. A manufacturing cost of a display apparatus may be decreased, and a delay time of an image display may be decreased.
