Abstract: A light board includes a light-emitting unit array including a plurality of light-emitting units arranged in an array and a driver backplane disposed on a backlight side of the light-emitting unit array. The driver backplane includes a base, a trace layer, and an insulating protection layer stacked successively in a direction away from the light-emitting unit array. The trace layer includes a plurality of traces and one or more bonding terminals each electrically connected to one of the traces. An orthographic projection of the insulating protection layer on the base overlaps the traces. The insulating protection layer includes one or more first opening each exposing one of the bonding terminals. The insulating protection layer is disposed on an outermost side of the side of the driver backplane away from the light-emitting unit array.

Abstract: The present invention provides a full grayscale subjective consistency optical data obtaining method and a splicing display panel, an initial splicing display panel includes splicing and disposing first display panel (liquid crystal display panel) and second display panel in different types. The method includes: obtaining a plurality of bonding point colors, sets of reference bonding point optical parameters and sets of bonding point optical parameters of the first display panel and the second display panel corresponding to the bonding point colors respectively, and determining non-bonding point optical parameters in the second display panel corresponding to non-bonding point colors between adjacent two of the bonding point colors. A display image of the second display panel under effect of each set of the bonding point optical parameters is subjectively consistent with a display image of the first display panel under effect of a set of the reference bonding point optical parameters.
