DISPLAY PANEL AND METHOD FOR MANUFACTURING DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2020/233305
Kind Code:
A1
Abstract:
Disclosed are an organic light-emitting diode display panel, and a method for manufacturing the organic light-emitting diode display panel. The organic light-emitting diode display panel comprises: a plurality of first light-emitting layers, which are configured to transmit light of a first color when being excited, wherein the various first light-emitting layers are arranged in a first direction (D1) and a second direction (D2), which intersects with the first direction (D1), in an array; and each of the first light-emitting layers comprises a shadow region (SR), and the shadow region (SR) is a peripheral region of the first light-emitting layer, and has a thickness less than a first thickness threshold; and a pixel definition layer (203), comprising a plurality of first openings which are covered by the corresponding first light-emitting layers, wherein each of the plurality of first openings defines a first light-emitting region of each of the plurality of first light-emitting layers; each of the first openings is provided with a reduced size in the first direction (D1), such that the corresponding first light-emitting region defined by the first opening is provided with a first offset tolerance range in the first direction (D1), and is provided with a second offset tolerance range in the second direction (D2); and within the first offset tolerance range, the corresponding first light-emitting region is allowed to offset in the first direction (D1), but does not overlap the shadow region (SR) of the corresponding first light-emitting layer, and within the second offset tolerance range, the corresponding first light-emitting region is allowed to offset in the second direction (D2), but does not overlap the shadow region (SR) of the corresponding first light-emitting layer, wherein the first offset tolerance range is basically equal to the second offset tolerance range.
