Embodiment Construction
[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] figure 2 It is a flowchart of a manufacturing method of a touch display panel in an embodiment of the present invention, such as figure 2 As shown, the manufacturing method of the touch display panel in the embodiment of the present invention includes the following steps:
[0021] S201: Provide a liquid crystal display panel that has been assembled;
[0022] S202: The Mylar tape is fixedly connected to the periphery of the surface on one side of the OCA adhesive and the OCA adhesive is extended from the outside of the Mylar tape to form a composite adhesive layer;
[0023] S203: The composite adhesive layer is aligned with the LCD panel, the OCA adhesive is aligned with the LCD panel of the LCD panel, and the Mylar tape inside the OCA adhesive is a...

The invention provides a manufacturing method for a touch display panel. The manufacturing method comprises the following steps that an assembled liquid crystal display panel is supplied, Mylar adhesive tape is fixedly connected with the periphery of the surface of one side of an OCA adhesive, the outer side of the Mylar adhesive tape stretches out of the OCA adhesive, and a composite adhesive layer is formed; the composite adhesive layer is attached to the liquid crystal display panel in an aligned mode; the portion, stretching outside the OCA adhesive, of the Mylar adhesive tape are folded and attached to the periphery of a frame of the liquid crystal display panel along the frame; a touch sensing layer is attached to the surface of the other side of the OCA adhesive in an aligned mode, and then the touch display panel is formed. According to the manufacturing method for the touch display panel, the Mylar adhesive tape and the OCA adhesive are fixed into a whole in advance and are flat to each other, the Mylar adhesive tape is attached along the OCA adhesive in the aligned mode, and therefore the aligned attaching step of the Mylar adhesive tape is omitted; the attaching flatness of the Mylar adhesive tape and the frame is high, and therefore occurrence of the wrinkling and cocking problems of Mylar adhesive tape attaching are reduced.
Description
Technical field [0001] The present invention relates to the technical field of touch display, in particular to a manufacturing method of a touch display panel. Background technique [0002] With the development of the information age and the acceleration of the pace of life, touch technology has gradually replaced the traditional mouse and keyboard due to its humanized design and simple and quick input, and has been widely used in various electronic products. Touch display panels are widely used due to their advantages of fast response, high sensitivity, good reliability, and high durability. The touch display panel mainly includes an aligned liquid crystal display panel (LCM) and a touch sensor layer (Touch Sensor). [0003] Figure 1A to Figure 1D Is a schematic diagram of the cross-sectional structure of the existing touch display panel in each step, see Figure 1A to Figure 1D As shown, the existing manufacturing method of the touch display panel is to attach Mylar glue 302 to t...
