Embodiment Construction
[0062] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0063] see Figure 1 to Figure 4 , this embodiment provides a method for manufacturing a display panel, including the following steps: manufacturing a thin film transistor 2 on a substrate 1, which corresponds to figure 1 Step 1 to Step 2 in. The substrate 1 is a glass substrate or a plastic substrate, and the thin film transistor (Thin Film Transistor, TFT) is used as a switch to control whether the lines on the display panel are turned on or not. The thin film transistor 2 includes a source, a drain, a gate and an active layer, and the thin film transistor 2 has a top gate structure or a bottom gate structure.
[0064] see figure 1 , in the thin film transistor with bottom gate structure, the gate 21 is located on the substrate 1...

The invention discloses a display panel and a manufacturing method. The manufacturing method comprises the following steps: manufacturing a second flat layer on a substrate, etching the second flat layer to form a first hole, and enabling the first hole to be used for accommodating a pixel light-emitting layer; manufacturing a pixel light-emitting layer, wherein the pixel light-emitting layer is arranged in the first hole; etching the second flat layer to form a second hole, wherein the second hole is arranged around the first hole; manufacturing an inner packaging layer, wherein the inner packaging layer is arranged at the second hole and used for preventing water vapor and oxygen from invading the pixel light-emitting layer; and manufacturing a cathode, wherein the cathode is connected with the pixel light-emitting layer and the inner packaging layer. According to the technical scheme, the inner packaging layer is established around each independent light-emitting sub-pixel to blockwater and oxygen invading along the inorganic film layer of the back plate, so that the protection on the display panel and the pixels is enhanced. Herein, the inner packaging layer is embedded into the second flat layer and has better bonding capacity with the second flat layer, so that invasion of water and oxygen is better blocked, and the pixel stability is maintained.
Description
technical field [0001] The invention relates to the field of display panel fabrication, in particular to a display panel and a fabrication method. Background technique [0002] The full name of AMOLED is: Active-matrix organic light-emitting diode, translated as: active matrix organic light-emitting diode or active matrix organic light-emitting diode, which is a display technology. Among them, "OLED" refers to an organic light emitting diode (Organic Light Emitting Diode, OLED) display; "AM" refers to an active matrix body or an active matrix body, referring to the pixel addressing technology behind it. Compared with the more traditional TFT-LCD display, it has excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, and fast response speed, and has become the mainstream display technology today. [0003] As a new type of thin film transistor technology, IGZO (indium gallium zinc oxide) display technology...
