Problems solved by technology

[0002] Micro-LED has developed into one of the hot spots of future display technology. Compared with the current LCD and OLED display devices, it has the advantages of fast response, high color gamut, high PPI, and low energy consumption; but its technical difficulties are many and complex, especially It is its key technology, mass transfer technology, and the miniaturization of LED particles has become a technical bottleneck. As the product of the combination of Micro-LED and backplane, Mini-LED has the characteristics of high contrast and high color rendering performance comparable to OLED. Slightly higher than LCD, only about 60% of OLED, easier to implement than Micro-LED and OLED, so Mini-LED has become a hot spot for major panel manufacturers
[0003] However, the wires connected to the driver circuit board (FPC) in the existing Mini-LED have a mesh structure. In order to avoid short-circuiting between different wires, it is necessary to design multiple metal layers so that different wires are designed in different metal layers. , leading to complex wiring design, and the design of multi-layer metal layers affects product yield and increases costs

Abstract

The application discloses a backlight module and a display device. The backlight module includes a substrate; a metal layer located on the substrate, the metal layer includes at least one signal wiring and at least one first signal connection line extending along a first direction, the at least one signal wiring and The at least one first signal connection line is arranged on the same layer; and at least one light emission control structure is located on the metal layer and distributed in at least one column, and at least one side of each column of the light emission control structure is correspondingly provided with one of the signal lines. and each of the light-emitting control structures in each column of the light-emitting control structures is connected to the corresponding signal wiring, and any two adjacent light-emitting control structures in each column of the light-emitting control structures pass through One said first signal connection line is connected. The application can simplify the wiring design, improve product yield, and reduce cost.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a backlight module and a display device. Background technique [0002] Micro-LED has developed into one of the hot spots of future display technology. Compared with the current LCD and OLED display devices, it has the advantages of fast response, high color gamut, high PPI, and low energy consumption; but its technical difficulties are many and complex, especially It is its key technology, mass transfer technology, and the miniaturization of LED particles has become a technical bottleneck. As the product of the combination of Micro-LED and backplane, Mini-LED has the characteristics of high contrast and high color rendering performance comparable to OLED. The slightly higher LCD is only about 60% of OLED, and it is easier to implement than Micro-LED and OLED. Therefore, Mini-LED has become a hot spot for major panel manufacturers. [0003] However, the wires con...
