Problems solved by technology

[0005] One is to use a single photolithography process to shape, that is, to use half light leakage in some areas. However, this method has too high requirements for photolithography, the process window is small, it is easy to remain, it is difficult, and the yield is low;
[0006] The second is to use two photolithography processes. However, when this method is used, part of the first pixel definition layer 13a will be developed at the same time as the second development, and the second pixel definition layer 13b is likely to remain due to the deep channel problem, making the process difficult.

Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no interveni...

Abstract

The invention discloses an AMOLED display device and a manufacture method thereof. The AMOLED display device includes a TFT backboard provided with a plurality of pixel electrodes and a drive transistor; a face board part arranged facing the TFT backboard and provided with a display face and a packaging face arranged opposite to the display face; a pixel definition layer disposed between the TFT backboard and the face board part and including a first pixel definition layer formed on the TFT backboard and a second pixel definition layer formed on the packaging face of the face board part, wherein the second pixel definition layer is connected with the first pixel definition layer fixedly. The AMOLED display device is comparatively simple in manufacture, high in yield rate and low in material cost.

Description

【Technical field】 [0001] The present invention relates to an AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) display device, in particular to an AMOLED display with a double-layer pixel definition layer Device and method of manufacture thereof. 【Background technique】 [0002] see figure 1 , AMOLED (Active Matrix Organic Light Emitting Diode Panel) display device 10 usually sets a pixel definition layer 13 on a TFT (Thin Film Transistor, Thin Film Field Effect Transistor) backplane 11 to insulate a plurality of pixel structures 15, for example, The pixel definition layer 13 is provided with a plurality of openings, and the red, green and blue pixel structures 15 are correspondingly disposed in the plurality of openings. [0003] Since the TFT backplane 11 of the AMOLED display device 10 is easily damaged by friction from a metal shadowmask during vapor deposition. Moreover, during...
