Title:
ORGANIC LIGHT-EMITTING DIODE DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/201096
Kind Code:
A1
Abstract:
An organic light-emitting diode display panel (20) and a manufacturing method therefor, and a display apparatus, belonging to the technical field of display. The organic light-emitting diode display panel comprises: a base substrate (201); a pixel defining layer (202) and multiple first electrodes (203) on the base substrate (201), wherein the pixel defining layer (202) defines, on the base substrate (201), multiple sub-pixel areas arranged in an array, one first electrode (203) is formed in each of the sub-pixel areas, and work functions of first electrodes (203) sequentially increase along a direction away from the center of the first electrodes (203); an organic light-emitting layer (204) on each first electrode (203); and a second electrode (205) electrically connected to the organic light-emitting layer (204), wherein the polarity of the first electrode (203) is different from that of the second electrode (205). According to the present invention, the problem in the related art of the uniformity of the brightness of light emitted by an organic light-emitting layer being poor is solved.
