Abstract

The invention relates to an LED chip assembly, a display panel and a preparation method. The LED chip assembly includes a substrate, a plurality of LED chips on the substrate, and at least two marker bases, the marker bases and the LED chips are formed on the same growth substrate, and can be transferred to the transient substrate together with the LED chips It is used for positioning in the transfer process of the LED chip. The LED chip assembly provides a new solution for setting alignment marks on the transient substrate. In this solution, the transfer process of the LED chip and the marking base can be realized together. , avoids the need to transfer the marking base and the LED chip to the transient substrate after setting the marking base on the substrate other than the growth substrate, improves the setting efficiency of the alignment mark on the transient substrate, and is conducive to improving the giant volume transfer efficiency.

Description

technical field [0001] The present invention relates to the technical field of LEDs, and in particular, to an LED chip assembly, a display panel and a preparation method. Background technique [0002] The radiation theory and structure of Light-Emitting Diode (LED) are different from traditional light sources, such as fluorescent lamps or incandescent lamps. LEDs have the advantages of low power consumption, long life and fast response time. In addition, LEDs are compact, shockproof, and environmentally friendly, so LEDs are widely used in the market. For example, LEDs can be used in display devices, indoor or outdoor lighting, data storage devices, communication devices, medical devices, and the like. [0003] The LED can be used as a backlight source of a display device, or can be used as a pixel unit of a display device after being reduced in size (micron level). And mass transfer technology has become the key to making small-sized LEDs as pixel units. In mass transfe...
