摘要： Micro LED display device and driving method thereof. The display device includes a display substrate and a data driving circuit. The display substrate includes multiple pixels, and each pixel includes a first subpixel and a second subpixel. The first subpixel has a first subpixel circuit and a first light-emitting element. The second subpixel has a second subpixel circuit and a second light-emitting element. The first subpixel circuit and the second subpixel circuit are configured independently. The data driving circuit is electrically connected to the first and the second subpixel circuits. The data driving circuit transmits a first data signal to the first subpixel circuits to drive the first light-emitting elements and a second data signal to the second subpixel circuits to drive the second light-emitting elements. The first data signal is a PWM signal, and the second data signal is a PAM signal.

摘要： A micro light-emitting diode display device includes a circuit substrate and a plurality of display pixels. The display pixels are arranged on the circuit substrate and are respectively electrically connected to the circuit substrate. Each display pixel includes a plurality of micro light-emitting elements. In each display pixel, a part of the micro light-emitting elements form at least one series-connection structure, and the micro light-emitting elements of the series-connection structure are within a wavelength range of the same lighting color. The circuit substrate respectively provides a same driving voltage to drive the micro light-emitting elements included in the series-connection structure of each display pixel and the micro light-emitting elements excluded from the series-connection structure.

摘要： A micro LED transparent display has a first display surface and a second display surface, which are opposite to each other. The micro LED transparent display includes a substrate, pixels and at least one grating layer. The first display surface and the second display surface are located on two opposite sides of the substrate, respectively. The pixels are arranged in arrays on the substrate, each of the pixels includes micro LEDs, and the micro LEDs are electrically connected to the substrate. The grating layer is disposed on the substrate, and the micro LEDs are located between the grating layer and the substrate. Lights generated from the micro LEDs of the pixels can be controlled by the grating layer, and the lights partially penetrate through the first display surface and are partially reflected and penetrate through the second display surface.
