Abstract

The invention discloses an organic electroluminescence display panel and a manufacturing method thereof, and a display apparatus. An organic light emitting layer capable of displaying a sub pixel anda virtual sub pixel synchronously can be evaporated on a substrate by virtue of a layered refined mask plate and a shielding part of a shielding mask plate; the area of the organic light emitting layer of a special-shaped virtual sub pixel in the virtual sub pixel is smaller than that of the organic light emitting layer in the display sub pixel of the same light emitting color, wherein multiple uniformly arranged evaporation patterns are arranged in a rectangular evaporation region of the refined mask plate; by virtue of the rectangular evaporation region, the difficulty of the refined mask plate net stranding process and the evaporation process is lowered; the shielding mask plate comprises at least one special-shaped opening region; the positive projection of each rectangular evaporationregion on the shielding mask plate covers one corresponding special-shaped opening region, so that it is ensured that the organic light emitting layer pattern evaporated on the edge of the special-shaped opening region can be fully fitted with the edge of the special-shaped pixel region, and full-screen display of the special-shaped pixel region is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence display panel, a manufacturing method thereof and a display device. Background technique [0002] At present, the screens of common display devices, such as monitors, televisions, mobile phones, tablet computers, etc., are usually regular rectangles. With the development of display technology, the full screen has a large screen-to-body ratio and an ultra-narrow bezel. Compared with ordinary display screens, it can greatly improve the visual effect of the viewer, and thus has received widespread attention. At present, in a display device with a full screen such as a mobile phone, in order to realize the functions of Selfie, video call and fingerprint recognition, a front camera, an earpiece, a fingerprint recognition area or physical buttons are usually arranged on the front of the display device. Such as figure 1 As shown in the structural diagra...
