Display device

A display device is disclosed that includes a display panel on which one or more sub-pixels including a light emitting device and a driving transistor for driving the light emitting device are disposed in a display area, and whose shape is changed during a transforming period, a timing controller for receiving image data and a command signal defining the transforming period, and converting the image data to output converted image data, and a data driving circuit for receiving the converted image data and outputting a data voltage, wherein, in the transforming period, at least one sub-pixel emits light based on the image data input to the timing controller, and emits light with a luminance lower than a luminance corresponding to a grayscale of the image data. Accordingly, there may be provided a display device capable of changing a shape during an image display period.

Display device with power management circuit for transforming period

A display device includes a display panel in which a plurality of subpixels including a light emitting element that emits light by a high potential voltage supplied to a driving voltage line, and a plurality of reference voltage lines connected to the plurality of subpixels to detect a characteristic value are disposed; a data driving circuit configured to supply a low potential voltage to the driving voltage line through the plurality of reference voltage lines; a base voltage switching circuit configured to control a ground voltage node connected to a cathode electrode of the light emitting element; a current detecting circuit configured to detect a current flowing between the base voltage node and a ground; and a timing controller configured to control the base voltage switching circuit and generate a defect detection signal for the driving voltage line according to a current detected by the current detecting circuit.

Display device and display driving method

A display device includes: a display panel, a driving printed circuit board connected to the display panel, a control printed circuit board connected to the driving printed circuit board, at least one cable which connects the driving printed circuit board and the control printed circuit board, and a hinge connecting module disposed at both ends of at least one cable. Therefore, it is possible to implement an image having a high resolution by increasing the number of driving printed circuit boards attached to the display panel.
