  • DISPLAY PANEL AND METHOD FOR MANUFACTURING THE SAME, DISPLAY DEVICE, AND TILED DISPLAY DEVICE
    Publication number: 20240097085
    Abstract: A display panel (10) includes a circuit backplane (1) and a reflective layer (3). The circuit backplane (1) includes a first main surface (11), a second main surface (12), and a plurality of side surfaces (13). The second main surface (12) is disposed opposite to the first main surface (11). The side surfaces (13) each connect the first main surface (11) and the second main surface (12). At least one side surface in the plurality of side surfaces (13) is a selected side surface (13a). The selected side surface (13a) is covered by the reflective layer (3), the reflective layer (3) being configured to be removed under a predetermined process condition.

  • Array substrate and preparation method thereof
    Patent number: 11239113
    Abstract: The present disclosure discloses an array substrate and a preparation method thereof. After a first passivation layer is formed, residual gas is directly drawn out of a closed chamber to prevent the residual gas from reacting to form an unstable layer on the first passivation layer. Furthermore, after the residual gas is drawn out, a preset gas fills the closed chamber, and is retained for a preset time period and then drawn out. The retaining of the preset gas can effectively alleviate the damage to the passivation layer by static electricity.
