Abstract

The invention discloses a splicing display panel, a preparation method of a splicing unit and a splicing display device.The splicing display panel comprises at least two splicing units. Each splicing unit comprises a substrate which is provided with a plurality of wiring holes penetrating through the substrate; a driving circuit arranged on the substrate base plate; a plurality of LED chips arranged at the side, provided with the driving circuit, of the substrate and conducted with the driving circuit; and a chip-on-film arranged at the side, opposite to the LED chips, of the substrate and electrically connected with the driving circuit through the wiring holes. A splicing seam formed when two adjacent splicing units are spliced is non-linear. The wiring hole is formed in the substrate, the driving circuit is conducted to the back face of the substrate base plate, the splicing seams of the splicing units are arranged to be non-linear, seamless splicing is achieved, and meanwhile the optical uniformity of the splicing seams is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a tiled display panel, a method for preparing the tiled unit in the tiled display panel, and a tiled display device including the tiled display panel. Background technique [0002] In recent years, LED (light-emitting diode, light-emitting diode) displays have developed rapidly, and as pixel sizes continue to decrease, application scenarios have become wider. From the original indoor and outdoor large-scale long-distance advertising screens to indoor and outdoor short-distance high-definition display screens, LED displays will become the mainstream of indoor and outdoor large-screen high-definition displays in the future. [0003] At present, large-screen LED displays mainly use module splicing technology, that is, small-sized LED modules are spliced ​​into large screens of any size. However, since the current patchwork is a linear splicing, and there will be a patchw...
