Abstract
The invention discloses a spliced screen and a preparation method thereof, and the preparation method comprises the following steps: providing an initial display module, the initial display module is defined with a display area and a non-display area, and the initial display module comprises a thin film transistor array layer and a light-emitting layer arranged on the thin film transistor array layer; wherein the thin film transistor array layer comprises a metal signal line extending from the display area to the non-display area; carrying out hollowing processing on the signal wires located in the non-display area to enable the signal wires located in the non-display area to form hollowing parts so as to obtain a transition display module; a cutting track is preset on the transition display module, and the cutting track is located at the center line of the hollowed-out part or located on the outer side of the center line of the hollowed-out part; and cutting the transition display module along the cutting track to obtain a target display module. According to the target display module, the metal signal lines can be prevented from being exposed in the air in the splicing process, the corrosion risk is reduced, and the reliability of products is improved.
Description
Technical field [0001] This application involves the field of display technology, which specifically involves a stitching screen and its preparation methods. Background technique [0002] The display panel can be divided into two categories: Passive Matrix (PM) and Active Matrix (AM) according to the driver. Essence [0003] The LED grille product on the traditional printing circuit board (PRINTED CIRCUIT BOARD (PCB board) uses a passive drive method, which will cause the display panel to have low resolution and cannot meet the high -end close -range viewing needs. Scene requirements. The LED on the glass back panel adopts a source of drive, which can realize high resolution, high -resolution requirements, meet more scene needs, and have congenital advantages in the field of transparent display, which can bring a better viewing experience to the audience. Can match the needs of high -end transparent scenes. [0004] At present, the LED display screen includes miniled and MicroLED...
