Embodiment Construction

[0049] The following is attached Figure 1-9 The application is described in further detail.

[0050] The embodiment of the present application discloses a mini-LED structure with splicing of partitioned cells. refer to figure 1 with 2 , including a PCB base carrier 1, a plurality of partition cells 2 are arranged on one surface of the PCB base carrier 1, and the partition cells 2 include a PCB partition carrier 21 electrically connected to the surface of the PCB base carrier 1 and a plurality of The mini-LED chips 22, a plurality of mini-LED chips 22 are fixedly connected to a surface of the PCB partition carrier 21 away from the PCB base carrier 1 and the mini-LED chips 22 are electrically connected to the PCB partition carrier 21. If it is found that the mini-LED chip 22 in a certain partition cell 2 cannot work normally, the worker can desolder the PCB partition carrier board 21 of the partition cell 2 and replace it with a new partition cell 2 . The number of mini-LED...

Abstract

The invention relates to a mini-LED structure with spliced partition cells and a production process, and belongs to the field of LED backlight, the mini-LED structure comprises a PCB base layer carrier plate, and a plurality of partition cells are arranged on one surface of the PCB base layer carrier plate; the partition unit grid comprises a PCB partition carrier plate and a plurality of mini-LED chips, the PCB partition carrier plate is electrically connected to the surface of the PCB base carrier plate, the mini-LED chips are fixedly connected to the surface, away from the PCB base carrier plate, of the PCB partition carrier plate, and the mini-LED chips are electrically connected with the PCB partition carrier plate. According to the invention, the condition that the mini-LED chip is inconvenient to deweld and replace is improved.

Description

technical field [0001] The present application relates to the field of LED backlights, in particular to a mini-LED structure and production process with partitioned cell splicing. Background technique [0002] According to the group standard of "General Technical Specifications for Mini LED Commercial Displays", mini-LED is defined as an LED device with a chip size between 50 and 200 μm. With the rapid development of mini-LED display technology, mini-LED display products have become increasingly popular. Began to be used in ultra-large-screen high-definition display, such as monitoring and command, high-definition studio, high-end cinema, medical diagnosis, advertising display, conference exhibition, office display, virtual reality and other commercial fields. [0003] In related technologies, the mini-LED backlight uses the entire FPC or PCB for circuit design and solid crystal. Taking the 13.3-inch mini-LED white light backlight panel as an example, the number of LED chips...
