In a sensing mode, the plurality of the first light sources is activated to generate and provide the first light for the sensing unit layer. In a displaying mode, the plurality of the second light sources is activated to generate the second light for displaying an image at the display side.

Abstract: A method for transferring micro devices is provided. The method includes the following operations: providing a carrier substrate and forming micro devices on the carrier substrate; forming a fixing layer on the carrier substrate, in which the fixing layer is at least in contact with bottom parts of the micro devices; patterning the fixing layer to selectively expose a portion of the micro devices; providing a transfer device correspondingly located on the carrier substrate, and picking up the exposed micro devices by the transfer device; and providing a receiving substrate and transferring the exposed micro devices to the receiving substrate.

Abstract: A method of transferring micro-devices is provided. A carrying unit including a carrying substrate, a plurality of electrodes, a dielectric layer covering the electrodes, and a plurality of micro-devices disposed on the electrodes, including a first micro-device and a second micro-device, are also provided. A voltage is applied to an electrode corresponding to the first micro-device, so that an electrostatic force generated on the first micro-device by the carrying unit is larger than a force generated on the second micro-device by the carrying unit. A transfer stamp contacts the first micro-device and the second micro-device, and moves when the transfer stamp contacts the first micro-device and the second micro-device and the electrostatic force is greater than the force generated by the carrying unit, so that the second micro-device is picked up by the transfer stamp and transferred to a receiving unit, and the first micro-device remains on the carrying unit.

Abstract: An LED display is provided in considering of both the human eye perception and inconsistent luminous efficiencies of LEDs in a red, blue, and green sub-pixels. A total area of a light-exiting surface of a red micro LED is larger than a total area of a light-exiting surface of a green micro LED so as to improve the problem that the sub-pixels of different colors have inconsistent luminous efficiencies.
