Title:
DISPLAY PANEL, PREPARATION METHOD THEREFOR, AND SPLICED SCREEN
Document Type and Number:
WIPO Patent Application WO/2021/233382
Kind Code:
A1
Abstract:
A display panel, which has a display region and a fan-out lead region, wherein the fan-out lead region is located within the display region. The display panel comprises a base, a pixel circuit layer, a plurality of fan-out leads, and an electrical field shielding pattern. The pixel circuit layer is disposed on the base and is located in the display region, the pixel circuit layer comprises a plurality of pixel circuits, at least one pixel circuit is located in the fan-out lead region, and the pixel circuit comprises a plurality of transistors. The plurality of fan-out leads are disposed between the base and the pixel circuit layer and are located in the fan-out lead region, and at least one fan-out lead is electrically connected to the pixel circuits. The electrical field shielding pattern is disposed between the pixel circuit layer and a film layer in which the plurality of fan-out leads are located, and the orthographic projection of the electrical field shielding pattern on the base at least covers the orthographic projection of an active layer pattern of the transistors of the pixel circuits located in the fan-out lead region on the base; and the electrical field shielding pattern is configured to access constant voltage and shield interference signals from the plurality of fan-out leads acting on the active layer pattern of the transistors of the fan-out lead region.
