The invention relates to an electroluminescent display and the production method thereof. The electroluminescent display includes a pixel drive structure and an electroluminescent structure. The pixel drive structure is equipped on a first rigid substrate, the electroluminescent structure is equipped on a second flexible substrate, and the electroluminescent structure and the pixel drive structure are pressed into an integral body via a transfer layer. The production method includes forming the pixel drive structure on the first rigid substrate; forming the electroluminescent structure on the second flexible substrate; and connecting the electroluminescent structure and the pixel drive structure into an electroluminescent display via press connection method. In the invention, by arranging the pixel drive structure and the electroluminescent structure on two substrates respectively, aperture ratio of the electroluminescent display is furthermost improved while efficiency of the electroluminescent display is ensured, therefore display effect is improved and contrast of the electroluminescent display is also improved.
Description
technical field [0001] The invention relates to electroluminescence display technology, in particular to an electroluminescence display device and a manufacturing method thereof. Background technique [0002] In order to be competitive in the field of flat panel displays, electroluminescent display devices are also developing towards large capacity, high resolution, low power consumption and large size. Due to the disadvantages of crosstalk, duty cycle, etc. in the passive matrix driving method, it is difficult to obtain high-quality display images, and cannot meet the needs of display terminals in the rapidly developing information age. The active matrix driving method has been widely used. in various display fields. Currently, the structure of the active matrix driven electroluminescence display device is mainly divided into a bottom emission (Bottom Emission) structure and a top emission (Top Emission) structure. [0003] Fig. 7 is a schematic diagram of an electrolumin...
