A tiling display apparatus includes a plurality of display modules connected with one another to configure a tiling screen and display division images and a system chip configured to change a display position of each of the division images, based on module arrangement information about each of the plurality of display modules, wherein seam patterns are configured to be coupled with adjacent display modules are provided in border regions of each display module, and each display module obtains, as the module arrangement information, connection state information about the seam patterns.

Tiling display apparatus

A display apparatus comprises: a display panel including pixels that emit light, wherein an amount of emitted light is controlled based on a data voltage, and an emission time of the pixels is controlled based on a duty ratio of an emission control signal applied to the pixels; a timing controller configured to control the emission control signal in an active period of one frame and in a blank period of the one frame, where the data voltage is supplied to the pixels during the active period of the one frame and the data voltage is maintained during the blank period of the one frame; and a gate driver configured to apply to the pixels the emission control signal having a first duty ratio during the active period and the emission control signal having a second duty ratio that is different from the first duty ratio during the blank period.

Display apparatus and flicker reduction method thereof

A tiling display apparatus includes a set board configured to generate a control command signal and a plurality of display modules connected to one another through a first interface circuit based on a serial communication scheme, for executing a target operation corresponding to the control command signal, and the first interface circuit is implemented with a bidirectional serial interface having a feedback loop type between adjacent display modules of the plurality of display modules.

A tiling display apparatus includes a plurality of display modules connected to one another to configure a screen, a set board configured to output an input data enable signal and image data synchronized therewith to one of the plurality of display modules, and first to N(where N is a natural number of 3 or more) timing controllers configured for the plurality of display modules, the first to Ntiming controllers are sequentially connected to one another in a first direction through a first interface line based on a cascading scheme and configured to receive the input data enable signal and the image data at different timings which are sequentially delayed and synchronize a display time of the image data on the basis of an independently generated output data enable signal.

The present disclosure discloses a display device and a driving method of the display device. The display device includes a display panel for displaying an image, a driver for driving the display panel, a controller for controlling the driver, and a duty cycle controller for defining an unknown area in which vertical resolution information is not known and a known area in which the vertical resolution information is known within one frame when a driving frequency of the display panel is changed, and varying a duty cycle for driving the known area.

Display device with duty cycle control and driving method thereof

Display device and driving method thereof

An infinitely expandable display apparatus and a driving method thereof are disclosed. An infinitely expandable display apparatus includes a cabinet including a plurality of display units each having an application specific integrated circuit (ASIC) embedded therein, a set board generating a driving command signal needed for driving of the cabinet, and a set interface circuit connecting the set board to the cabinet. The plurality of display units are connected to one another through a unidirectional interface circuit, and at least one of the plurality of display units transfers the driving command signal and an execution result signal based thereon to a neighbor display unit on the basis of a cascading scheme.
