A display device and an operating method of the display device are provided. The display device includes a first light emitting diode (LED), a first switch, a second switch, a second LED, a third switch, and a first controller. A first terminal of the first switch receives a first electrical signal. A first terminal of the second switch receives a second electrical signal. A first terminal of the third switch receives a third electrical signal. Here, whether the first switch, the second switch, and the third switch are switched on or off is determined by whether the first LED and the second LED are damaged or not. The first controller is configured to detect whether the first LED and the second LED are damaged or not, generate the second electrical signal and the electrical signal, and generate a plurality of control signals controlling the first switch to the third switch.

Display device and operating method thereof

A display module including display pixels, driving circuit and first switches is provided. The display pixels are arranged in columns and rows in the display area, and every display pixel includes sub-pixels. The display pixels form pixel rows along the first direction, and the sub-pixels of the display pixels form sub-pixel columns along the second direction. The color of the light emitting from the sub-pixels of the same sub-pixel column are substantially the same. The first direction and the second direction are substantially perpendicular. The driving circuit includes signal connectors, and every signal connector connects one of the pixel rows. The first switch is connected between a power source and one of the pixel rows, transmitting driving signal. The first switch is controlled by the driving circuit. A display device and a driving method are also provided.

Display module with high resolution grayscale, display device, and driving method thereof

A pixel circuit includes a first lighting circuit, a second lighting circuit, and a compensation circuit. A first light emitting element of the first lighting circuit receives a first driving current when the first transistor switch of the first lighting circuit is turned on. The second light emitting element of the second light emitting circuit receives a second driving current when the second transistor switch of the second light emitting circuit is turned on. When the first light emitting element and the second light emitting element are driven by the first driving current and the second driving current, the compensation circuit provides a compensation current to the first light emitting element or the second light emitting element according to a difference in impedance between the first light emitting circuit and the second light emitting circuit.
