preparation example Construction
[0138] The preparation method of the present invention comprises steps:
[0139] provide a base;
[0140] An electrode layer, a light-emitting layer and a modulation layer are sequentially prepared on the substrate, or a modulation layer, a light-emitting layer and an electrode layer are sequentially prepared on the substrate to obtain an electroluminescence tetrode.
[0141] Of course, the electrode layer, the light emitting layer and the modulation layer are sequentially prepared on the substrate, or after the modulation layer, the light emitting layer and the electrode layer are sequentially prepared on the substrate, the preparation method may further include the steps of:
[0142] Remove substrate.
[0143] The resulting electroluminescent tetrode then does not contain the substrate, and if the substrate is not removed, the resulting electroluminescent tetrode contains the substrate.

Abstract
The invention discloses an electroluminescent tetrode integrating luminescence, switch and color control, and a control method thereof. The electroluminescent tetrode comprises an electrode layer, a luminescent layer and a modulation layer which are arranged in sequence; the luminescent layer comprises at least two luminescent sub-layers; the electrode layer comprises at least two electrodes, and every two adjacent electrodes are arranged at intervals; and the electrodes and the luminescent sub-layers are arranged in a one-to-one correspondence mode, and the modulation layer is used for controlling all the luminescent sub-layers. The luminescent layer is divided into at least two luminescent sub-layers, the electrode layer is divided into at least two electrodes which are arranged at intervals, and the electrodes and the luminescent sub-layers are in one-to-one correspondence, so that the luminescent sub-layers can be respectively controlled through the modulation layer, and the luminescent sub-layers can form a pixel, namely, a control signal is given to the modulation layer; therefore, each luminescent sub-layer can be controlled in an integrated manner.
Description
technical field [0001] The invention relates to the technical field of electroluminescence, in particular to an electroluminescent tetrode integrating light emission, switching and color control and a control method thereof. Background technique [0002] The full-color display unit is an important part of intelligent electronic devices, so the display unit, like other electronic components, is facing the needs of miniaturization, integration and intelligence. With the introduction of the concept of system-level integration of electronic devices, more and more multifunctional electronic devices have aroused people's interest. [0003] On the other hand, organic electronics is considered to be the development direction of flexible electronics in the future. In recent years, research on organic transistors (OTFTs) has made remarkable progress, and active-matrix organic light-emitting diode (OLED) displays using organic transistors have also been reported a lot. In the widely ...
