Abstract: A display module configured to form a portion of a modular display device including a plurality of display modules includes first to third I2C communication interfaces and a processor. The processor is configured to: receive, via the first I2C communication interface from a first display module adjacent in a first direction, an x coordinate value of the first display module; receive, via the second I2C communication interface from a second display module adjacent in a second direction, a y coordinate value of the second display module; identify x and y coordinate values of the display module based on the received x and y coordinate values; transmit, via the third I2C communication interface, the identified x coordinate value to a third display module adjacent in a third direction; and transmit, via the third I2C communication interface, the identified y coordinate value to a fourth display module adjacent in a fourth direction.

Abstract: Disclosed is a display apparatus in which each pixel corresponds to at least one light-emitting element. The display apparatus includes a display including a plurality of pixels, a driver configured to drive a plurality of light-emitting elements constituting the plurality of pixels, and a processor configured to control the driver to drive the plurality of light-emitting elements based on a first pulse width modulation signal having a duty corresponding to a grayscale of an input image, and to control the driver to drive light-emitting elements constituting a specific pixel, among the plurality of pixels, using a second PWM signal having a duty corresponding to the grayscale of the input image, wherein a frequency of the first PWM signal is different from a frequency of the second PWM signal.

Abstract: A display device and a control method therefor are disclosed. The display device includes: a display; a transmitter configured to transmit an infrared (IR) signal; and one or more processors configured to: control the display to display a multi-screen including a plurality of images based on a plurality of image signals received from a plurality of source devices, each of the plurality of source devices using a same IR protocol; perform, based on a user command indicating a first image from among the plurality of images, a process for selectively controlling a first source device, from among the plurality of source devices, which provides the first image; and transmit an IR signal for selectively controlling the first source device through the transmitter.
