Display panel, splicing display device and method for preparing the same

A splicing display device, comprising:

• a first sub-screen and a second sub-screen that are spliced with each other along a first direction, wherein each of the first sub-screen and the second sub-screen includes a display panel, comprising:
• a display area, and
• a non-display area surrounding periphery of the display area, and
• the display panel comprises:
• a driving chip located in the non-display area at one side of the display area in a first direction;
• and
• a pixel structure comprising a plurality of first repeating units which are located in the display area, the first repeating unit comprising a first display pixel group and a first virtual pixel group which are disposed side by side along the first direction, wherein the first display pixel group comprises a plurality of first display sub-pixels disposed along a second direction, and the first virtual pixel group comprises a plurality of first virtual pixel bits disposed along the second direction, the first direction intersects with the second direction;
• wherein within the first repeating unit, an ordering of emissive colors of the plurality of first display sub-pixels along the second direction is in reverse to a preset ordering of emissive colors of the plurality of first virtual pixel bits along the second direction;
• and
• wherein within the first sub-screen, the driving chip is located at one side of the pixel structure away from the second sub-screen;
• within the second sub-screen, the driving chip is located at one side of the pixel structure away from the first sub-screen;
• and
• wherein within the first repeating unit of one of the first sub-screen and the second sub-screen, the first display pixel group is located at one side of the first virtual pixel group away from the driving chip, and within the first repeating unit of the other of the first sub-screen and the second sub-screen, the first display pixel group is located at one side of the first virtual pixel group near the driving chip.

A method for preparing a splicing display device, comprising:

• providing a plurality of array substrates, the array substrate comprising a driving chip and an electrode arrangement structure which are spaced in a first direction, wherein the electrode arrangement structure comprises a plurality of electrode repeating units, and the electrode repeating unit comprises a first electrode group and a second electrode group which are disposed side by side in the first direction, wherein the first electrode group comprises a plurality of first electrode units which are disposed side by side along a second direction, and the second electrode group comprises a plurality of second electrode units which are disposed side by side along the second direction and electrically connected with the first electrode units, the first direction intersects with the second direction;
• transferring light-emitting chips of multiple colors to one of the array substrates and electrically connecting the light-emitting chips with the first electrode units to form a first sub-screen;
• transferring light-emitting chips of multiple colors to another one of the array substrates and electrically connecting the light-emitting chips with the second electrode units to form a second sub-screen, wherein an ordering of emissive colors of the light-emitting chips along the second direction in the first sub-screen is in reverse to an ordering of emissive colors of the light-emitting chips along the second direction in the second sub-screen;
• and
• splicing the first sub-screen and the second sub-screen along the first direction, wherein within the first sub-screen, the driving chip is located at one side of the electrode arrangement structure away from the second sub-screen, and within the second sub-screen, the driving chip is located at one side of the electrode arrangement structure away from the first sub-screen.
