Definitions

  • Diode matrix for controlling displays with organic diodes and manufacturing processes for this
  • the invention relates to a diode matrix for controlling displays and a production method therefor, the diode matrix comprising at least one (partially) organic diode and at least partially being able to be produced using printing technology.
  • the insulation material which usually consists of tantalum oxide (Ta 2 0 5 ). This makes this technology very expensive and it is difficult to implement it on a flexible film.
  • the object of the present invention is to create a diode or a diode matrix which shows a symmetrical characteristic curve for driving displays and which consists at least in essential functional layers of predominantly organic material.
  • the subject matter of the invention is a diode matrix with a symmetrical characteristic which, although implemented using MIM technology, has an organic material in its core, as a semiconducting material.
  • the invention also relates to a diode matrix which can be produced at least partially by printing technology.
  • the invention relates to a method for producing a diode matrix, in which at least one functional layer of a diode is applied to a substrate or a lower layer in terms of printing technology.
  • an organic semiconductor is introduced in the middle between two conductive functional layers, be it metals or organic conductors.
  • the resulting diode like the diodes manufactured using MIM technology, shows a symmetrical characteristic.
  • an organic semiconducting material can also be used as an intermediate layer in the context of MIM technology in a matrix of diodes, each of which has a symmetrical characteristic.
  • an organic material is used here for the first time (it is important that this material can be separated from the solution) as a semiconductor material, which makes completely new applications of technology possible because of an improved economic efficiency further spreading the technology paves the way.
  • the invention enables simple and inexpensive activation for matrix displays, in particular for OLED displays.
  • the invention proposes to implement a diode array using organic diodes, in particular using printed organic diodes, which provide a switch matrix for controlling the display.
  • organic diode * here encompasses all types of fully organic, partially organic and other diodes which have at least one functional layer made of organic material.
  • organic material and / or “functional polymer” here encompasses all types of organic, organometallic and / or inorganic plastics, which are referred to in English as "plastics *". These are all types of substances with the exception of Semiconductors that form the classic diodes (germanium, silicon) and the typical metallic conductor, so there is no restriction in the dogmatic sense to organic material as carbon-containing material, but rather the broad use of, for example, silicones. Furthermore, the term should not be subject to any restriction with regard to the molecular size, in particular to polymeric and / or oligomeric materials, but the use of “small molecules” is also entirely possible.
  • Nanoparticulate semiconductors are also to be recorded (such as ZnO, Ti02, CdSe, CIS nanoparticles), which can be processed from the solution.
  • the method for producing the diode matrix is preferably in terms of printing technology, with at least one functional layer being applied in terms of printing technology to a substrate or a lower layer.
  • the MIM unit is preferably applied using printing technology, and particularly preferably the entire diode matrix is produced using printing technology.
  • the invention for the first time presents a matrix of diodes, each of which comprises a symmetrical characteristic curve and an intermediate layer made of a semiconducting organic material arranged between two conductive layers.
