Abstract: A timing controller is provided. A data enable signal in a timing control module is regenerated by a signal regenerating module. A number of vertical valid display rows is regenerated as a vertical valid display period. A total charge time of all rows of pixels in each frame can be increased effectively. A horizontal blanking period is changed sequentially in a row-by-row manner, thereby compensating charge effects of rows of pixels accurately.

Abstract: The present invention relates to a backlight module and a preparation method therefor, and a display panel. According to the present invention, solid white ink is attached to a second base plate, and then the solid white ink corresponding to positions of bonding pad units is removed by means of laser engraving, so as to prevent the screen-printing white ink from damaging the second base plate. Aligned assembling is performed on a first assembly and a second assembly using a vacuum pairing device. The vacuum pairing device may be reused in other preparation processes of the display panel. Therefore, the device investment can be reduced, and the production costs can be lowered.

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: A spliced screen and a display terminal are disclosed. In the spliced screen, a structural component is disposed on two adjacent display panels and covers a splicing gap between the two adjacent display panels. A lamp plate is disposed on a surface of the structural component. When the spliced screen displays an image, a plurality of luminescent bodies disposed on the lamp plate close to the display panels also emit light, thereby preventing black strips from appearing on the image. In the spliced screen, a viewing angle of the display panels and a viewing angle of the lamp plate are same, so that a brightness of the display panels and a brightness of the lamp plates are same when the spliced screen is viewed from a lateral side. As such, display quality is improved.
