印刷型电致发光显示器及其制作方法
摘要：
本发明公开了一种印刷型电致发光显示器及其制备方法。该印刷型电致发光显示器包括基板、驱动电路、图案化像素电极、第一像素区域层、第二像素区域层、发光层以及顶电极。基板上设有TFT阵列；基板上表面设有驱动电路以及多个图案化像素电极；第一像素区域层设在基板的上表面且覆盖各个图案化像素电极的边缘；第二像素区域层设在第一像素区域层上方，不同颜色子像素相邻区的第二像素区域层之间围成墨水沉积区，且不同颜色子像素相邻区的第二像素区域层的宽度以及高度均分别大于相同颜色子像素相邻区的第二像素区域层的宽度以及高度；各个墨水沉积区内均设有发光层，发光层的上表面沉积有顶电极。该印刷型电致发光显示器辨率高、抗干扰好。
摘要（英）：

The invention discloses a printed light-emitting display and a fabrication method thereof. The printed light-emitting display comprises a substrate, a driving circuit, patterned pixel electrodes, first pixel regional layers, second pixel regional layers, light-emitting layers and top electrodes, wherein a TFT array is arranged on the substrate, the driving circuit and a plurality of patterned pixel electrodes are arranged on an upper surface of the substrate, the first pixel regional layers are arranged on the upper surface of the substrate and cover an edge of each patterned pixel electrode,the second pixel regional layers are arranged above the first pixel regional layers, ink deposition regions are encircled by the second pixel regional layers adjacent to sub-pixels with different colors, the width and the height of the second pixel regional layer adjacent to the sub-pixels with different colors are respectively larger than the width and the height of the second pixel regional layer adjacent to the sub-pixel with the same color, each light-emitting layer is arranged in each ink deposition region, and the top electrodes are deposited on upper surfaces of the light-emitting layers. The printed light-emitting display is high in resolution and good in interference resistance.
