Provided is a display module including a communication interface; and a plurality of driver integrated circuits (ICs), wherein a first driver IC among the plurality of driver ICs is configured to: based on obtaining a driving signal from an external device through the communication interface, provide the driving signal to a second driver IC adjacent to the first driver IC so that the driving signal is sequentially provided to remaining driver ICs among the plurality of driver ICs, and provide, to a second display module among the plurality of display modules, the driving signal based on module connection information including whether the second display module is connected to any one display module among the plurality of display modules by a daisy chain method.

Display module, modular display apparatus comprising a plurality of display modules and control method thereof

A display device includes a communicator; a memory; a display panel including a plurality of display modules; and one or more processors. The processor receives position information and corrected pixel value of a first area in a first display module; identifies a pixel corresponding to the first area based on the position information; obtains a correction coefficient corresponding to the identified pixel based on the corrected pixel value and an output pixel value of the identified pixel; obtains correction coefficients corresponding to each of a plurality of remaining pixels based on the correction coefficient and a distance between the identified pixel and each of the remaining pixels and stores same in a memory; processes an input image based on the correction coefficients, and controls the display panel to display the processed input image. The device thereby improves display uniformity between display modules more effectively.

Display device and control method therefor

A display device is provided. The display device includes a light emitting diode (LED) module including a plurality of LEDs; a plurality of driving integrated chips (ICs), each of the plurality of driving ICs being configured to apply voltages to a corresponding group of the plurality of LEDs; and a controller. The controller is configured to identify a first voltage corresponding to a first LED from among the plurality of LEDs based on image data, identify a first LED driving voltage as the first voltage or a second voltage based on the first voltage and a reference value, and control a first driving IC, from among the plurality of driving ICs, that corresponds to the first LED based on the first LED driving voltage.
