Abstract: A display includes micro LEDs connected to a color conversion layer and driver ICs connected to the micro LEDs via an electrically connecting layer. Each micro LEDs includes an N pad and a P pad. The micro LEDs emit light of a same color, and the color conversion layer converts the light into various colors. The electrically connecting layer includes elongated negative electrodes connected to the N pads and elongated positive electrodes connected to the P pads. Each driver IC includes a first group of bonding pads on a face, a second group of bonding pads on an opposite face, and conductors for connecting the first group of bonding pads to the second group of bonding pads. Each bonding pad in the first group is connected to an elongated negative or positive electrode. The circuit board is connected to the second group of bonding pads of each driver IC.

Abstract: A touch panel includes a display substrate, pixel units supported on the display substrate, an electronic circuit for electrically connecting the pixel units to one another, and a molded resin portion for enclosing the pixel units. Each of the pixel units includes three miniature light-emitting diodes for emitting red light, green light and blue light respectively, a sensor, and a driver integrated circuit electrically connected to the miniature light-emitting diodes and the sensor.

Abstract: A method for making a light-emitting device includes providing a driver IC wafer with multiple control circuits. Groups of tiny light-emitting diodes are stacked on the driver IC wafer and electrically connected to the control circuits. Each of the groups comprises a tiny light-emitting diode for emitting red light, a tiny light-emitting diode for emitting green light and a tiny light-emitting diode for emitting blue light. The groups of tiny light-emitting diodes on the driver IC wafer are packaged. The driver IC wafer is cut into driver integrated circuits. Each of the driver integrated circuits includes one of the control circuits electrically connected to one of the groups of tiny light-emitting diodes. Thus, pixel units are provided. The pixel units are transferred to a display substrate and the control circuits of the pixel units are connected to a circuit of the display substrate. Thus, a single light-emitting device is provided.

Abstract: A method is provided for aligning micro light-emitting diodes. A platform is provided with arrays. Each of the arrays includes grooves. The platform is used to receive magnetic micro light-emitting diodes. Magnetic attraction and vibration are alternately exerted on the platform to cause the magnetic micro light-emitting diodes to fall into the grooves in a correct orientation. It is determined whether the magnetic micro light-emitting diodes fill the platform. Mass transfer is executed if the magnetic micro light-emitting diodes fill the platform.

Abstract: A laser-based locator includes a column, an axle, a rectilinear track, a sliding element and a laser source. The axle is supported by the column. The rectilinear track is connected to the axle and rotatable relative to the column between an original position and a lifted position. The rectilinear track extends parallel to the column in the original position. A length of the rectilinear track intersects a height of the column in the lifted position. The sliding element is supported on the rectilinear track so that the sliding element is reciprocated along the rectilinear track. The laser source is rotationally connected to the sliding element and operable to emit a laser.
