The present disclosure relates to an image display apparatus and a video wall including the same. An image display apparatus according to an embodiment of the present disclosure includes: a panel including a plurality of light emitting diodes; and a driving controller configured to output a scan signal for each of a plurality of subframe periods, and output a data signal for displaying an image, to the plurality of light emitting diodes, and the driving controller is configured to divide at least some subframe periods among the plurality of subframe periods into a plurality of group periods, and separately drive the light emitting diodes during at least some periods among the plurality of group periods. Accordingly, luminance non-uniformity between a plurality of light emitting diodes may be reduced.

Image display apparatus, and video wall including the same

A liquid crystal display and a method of driving the same are disclosed. The liquid crystal display includes a timing controller, N source drive integrated circuits (ICs), where N is an integer equal to or greater than 2, N pairs of data bus lines, each of which connects the timing controller to each of the N source drive ICs in a point-to-point manner, a lock check line that connects a first source drive IC of the N source drive ICs to the timing controller and cascade-connects the N source drive ICs to one another, a feedback check line that connects a last source drive IC of the N source drive ICs to the timing controller.
