Embodiment Construction
[0043] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0044] As mentioned in the background art above, the existing mass transfer LED chip transfer tact is relatively low, resulting in a very low yield rate. The reason is that in the existing Micro-LED color display panels, the distribution of LED chips that need to be transferred by mass transfer technology is relatively scattered, and the same LED chip needs to be used for too many mass transfer times, so that the existing giant The transfer tact in the mass transfer pro...

The invention discloses a preparation method of a display panel with a hybrid structure, and the display panel. The preparation method of the display panel comprises the steps: providing a driving back plate, wherein the driving back plate comprises a blue sub-pixel area, a green sub-pixel area and a red sub-pixel area, one blue sub-pixel area, one green sub-pixel area and one red sub-pixel area form an area occupied by a pixel unit, in the area occupied by the same row of pixel units, the sub-pixel areas of the same color in the areas occupied by different pixel units are adjacently arranged,and in the area occupied by the same column of pixel units, the sub-pixel areas of the same color in different pixel unit areas are arranged adjacently; forming an LED electrode, a first reflection electrode and a second reflection electrode on the driving back plate; transferring a blue-light LED chip to the driving back plate, and correspondingly and electrically connecting the blue-light LED chip with the LED electrode; and forming a green light organic light emitting device and a red light organic light emitting device. According to the technical scheme provided by the embodiment of the invention, the transfer beat and the yield of a large number of transferred LED chips are improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a method for preparing a display panel with a hybrid structure and the display panel. Background technique [0002] Micro-LED display technology has the advantages of low power consumption, high brightness, high color saturation, fast response, long life and high efficiency, and is considered to be the most competitive next-generation display technology. [0003] In the Micro-LED colorization solution, mass transfer technology is generally used to transfer millions or even tens of millions of LED chips to the driver backplane. However, the transfer tact of the existing mass transfer process is relatively low, resulting in a very low yield rate. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for preparing a display panel with a hybrid structure and the display panel, so as to improve ...
