Improved parallel all colour organic electroluminescence display apparatus and mfg. method thereof

Abstract

The invention discloses a modified parallel full color organic electroluminescent display unit and the making method thereof, mainly arranging a first organic light emitting unit in the vertical extending position of the first color photoetching glue on a color filter, arranging a second organic light emitting unit in the vertical extending position of the second color photoetching glue, arranging a third organic light emitting unit in the vertical extending position of the third color photoetching glue, forming a fourth organic light emitting unit in the vertical extending position of the first, second and third color photoetching glues, filtering light sources of various colors of the organic electroluminescent unit by the color filter and arranging these light sources in groups, thus achieving the purpose of full color.

Description

technical field [0001] The invention relates to an improved side-by-side full-color organic electroluminescence display device and a manufacturing method thereof, which can not only effectively improve the light source penetration rate and color saturation, but also improve the production yield. Background technique [0002] In many displays, how to achieve full-color display technology is often the key to the success of the display development. As far as organic electroluminescence display devices (OLEDs) are concerned, the most common methods to achieve full-color display functions are: Two of the following: [0003] 1. Three primary colors independent pixel light emission: the organic electroluminescent components that can produce the three primary colors of red (R), green (G) and blue (B) are separately set up, and the three color lights are mixed and matched in an appropriate proportion to produce full-color display effect. [0004] However, since the organic electrol...

Problems solved by technology

[0008] In addition, before the organic light emitting unit 23 is arranged on the transparent substrate 11, a masking alignment procedure needs to be performed first, wherein, if an error occurs in the masking alignment procedure, it will directly affect the arrangement of the organic light emitting unit 23, for example , the shielding alignment procedure of the second organic light emitting unit 233 is inaccurate, which will cause a deviation in the setting position of the second organic light emitting unit 233 and cause an error in the original setting position of the second organic light emitting unit 233 area 239, since the second organic light emitting unit 233 is not provided on the error area 239, the error area 239 will not be able to generate the second light source S2, resulting in a reduction in the active area of ​​the second organic light emitting unit 233, from the original The luminous area A1 is reduced to the luminous area A2, thereby affecting the luminous brightness of the second light source S2 and the display quality of the display device

[0009] For this reason, how to design a novel improved side-by-side full-color organic electroluminescent display device and its manufacturing method in view of the problems encountered in the above-mentioned known technologies, which can overcome the problems caused by the evaporation process and the shielding alignment. Loss of efficiency can not only reduce the production cost and help to improve the product yield, but also has the effect of improving the light source transmittance and color saturation, which is the focus of the invention.
