Narrow bezel display backplane, preparation method thereof, and display

Abstract

The present invention provides a narrow-frame display backplane, a preparation method thereof, and a display, wherein the narrow-frame display backplane includes a chip mounting auxiliary structure arranged on the backplane body, and the chip mounting auxiliary structure includes a first dielectric layer, the front side of the first dielectric layer is provided with a first contact point and a first metal connection line for mounting the LED chip, and the reverse side of the first dielectric layer is provided with a first through hole, and the first through hole The position of the hole corresponds to the position of the initial contact point on the backplane body, a conductive material is arranged in the first through hole, and the first metal connection line is used to connect the first contact point with the Conductive material in the first via. The present invention can realize the installation of the LED chip on the first contact point on the front surface of the first dielectric layer, so that the LED chip has a larger installation space, and there is no need to reserve a data wiring area on the backplane body, thereby Effectively reduces the frame of the display back panel.

Description

technical field [0001] The invention relates to the field of display backplanes, in particular to a narrow-frame display backplane, a preparation method thereof, and a display. Background technique [0002] Mini / Micro LED displays have good stability, long service life, and advantages in operating temperature. At the same time, they also inherit the advantages of LED low power consumption, color saturation, fast response speed, and strong contrast. Application prospect. [0003] Such as figure 1 The shown Micro-LED display backplane includes several pixel areas, and each pixel area includes a red LED, a blue LED, and a green LED. The RGB pixel area is the display AA area, and the A and B areas outside the display AA area are the data wiring area. Since the LED driver is driven by each LED with a separate current and there are thousands of data lines, the width of the data wiring area is relatively large. Wide, so that the border of the display will be very large. When the...
