Problems solved by technology

[0006] The manufacturing process of this prior art requires the cathode partition wall 3 to automatically pattern the cathode layer 5, but the resolution of the cathode partition wall 3 is not easy to improve, so the aperture ratio is difficult to improve, so the aperture ratio of the display will be due to the existence of the cathode partition wall 3 And reduce, and in order to manufacture the inverted trapezoidal structure, it needs to use expensive chemical gain amplification photoresist, and the angle of the inverted trapezoid is not easy to control, thus causing the problems of low yield and high cost

Embodiment Construction

[0024] In order to have a deeper understanding and recognition of the features, purposes, and effects of the present invention, the preferred embodiments are now listed and described in conjunction with the accompanying drawings as follows:

[0025] Please refer to Fig. 4, which is a schematic view of the appearance of the strip-shaped convex body 30 of the present invention, which is elongated and can be arranged on a substrate 15. The strip-shaped convex body 30 is respectively provided with two opposite A first side 301 and a second side 302 , and the angle between the first side 301 and the substrate 15 forms an obtuse angle, and the angle between the second side 302 and the substrate 15 forms an acute angle.

[0026] If the strip-shaped convex body 30 is made of organic material, it can be manufactured by oblique exposure. The manufacturing method includes procedures such as organic material coating, pre-baking, oblique exposure, development, and curing. The material of b...

Abstract

The invention discloses a bearing structure, comprising a substrate made with plural bar raised bodies, where the bar raised body has a first side and a second side opposite in the axial direction, the included angles between the first and second sides and the substrate are an obtuse angle and an acute angle, respectively, and the baring structure is made with an organic electroluminescent structure with plural subpixels, and the organic electroluminescent structure is made with a gap below the second side of each bar raised body so that the organic electroluminescent structure is differentiated into different subpixels in gapless form, thus increasing display opening rate.

Description

technical field [0001] The invention relates to an organic electroluminescence display, in particular to an organic electroluminescence structure with a high aperture ratio and a manufacturing method thereof. Background technique [0002] Organic electroluminescent displays (OLEDs) can be divided into passive matrix driven OLEDs and active matrix driven OLEDs according to their driving methods. They mainly use current to drive organic thin films to emit light. The organic electroluminescent structure includes an anode layer, an organic layer, and a cathode layer. [0003] In order to obtain high-efficiency light-emitting characteristics, the general method used in organic electroluminescent displays is to make organic materials into organic electroluminescent structures by evaporation, which uses metal shielding and vacuum evaporation to form fine patterns of organic materials. change. [0004] Please refer to FIG. 1-1, FIG. 1-2, and FIG. 1-3, which are schematic diagrams ...
