AI Technical Summary

Problems solved by technology

First of all, in terms of process, since the use of shielding will inevitably produce alignment errors, it is known that the organic light-emitting matrix 16 of the organic electroluminescent structure must use three shields, thus increasing the risk of poor alignment. Poor alignment of the light-emitting matrix 16 will cause problems such as shadow effects, resulting in poor display quality
In addition, when the size of the organic electroluminescent panel to be manufactured is large, a large shield must be used, and the large shield is likely to produce a bending effect, which will also cause deviations in the pattern transfer of the organic light emitting matrix 16

Description

technical field [0001] The present invention relates to an organic electroluminescent structure and a manufacturing method thereof, in particular to an organic electroluminescent structure having a light-emitting and electron-transporting layer with dual functions of organic light-emitting and electron-transporting, and an organic electroluminescent structure that can reduce the use of A method for fabricating an organic electroluminescent structure using a number of shields that defines an organic light-emitting layer. Background technique [0002] Flat Panel Displays have incomparable advantages over traditional Cathode Ray Tube (CRT) displays, such as power saving, no radiation, light weight and short size, etc. Therefore, Flat Panel Displays have gradually replaced CRT displays. With the improvement of flat-panel display technology, the price of flat-panel display products continues to decrease, making flat-panel displays more popular and developing towards large display...
