Touch screen and LCD (liquid crystal display) module attaching jig group and attaching method

Abstract

The invention discloses a touch screen and LCD (liquid crystal display) module attaching jig group and an attaching method. The attaching jig group comprises a first jig used for attaching an LCD panel and a touch screen as well as a second jig used for attaching a backlight module and the whole after attachment of the LCD panel and the touch screen, wherein the first jig comprises a first bottom plate and four first positioning blocks connected with four corners of the first bottom plate respectively, and a first LCD panel positioning part and a touch screen positioning part are arranged in the position where each first positioning block and the first bottom plate are connected; the second jig comprises a second bottom plate and four second positioning blocks connected with four corners of the second bottom plate respectively, and a second LCD panel positioning part and a backlight module positioning part are arranged in the position where each second positioning block and the second bottom plate are connected. The LCD panel and the touch screen are attached together in a shape border aligning manner firstly, the consistency of peripheral borders of a product display area is guaranteed, then the whole and the backlight module are attached together in a shape border aligning manner, and the contour dimension of the backlight module is guaranteed very well.

Description

technical field [0001] The invention relates to the technical field of liquid crystal touch screen production, in particular to a bonding fixture and a bonding method for a touch screen and a liquid crystal module. Background technique [0002] At present, with the development of science and technology and the touch control of electronic display products, more and more touch screen and liquid crystal module lamination products have appeared in the market; however, in the production process, the touch screen and liquid crystal Alignment methods are two methods: snapping the outline frame alignment and snapping the display area frame alignment: [0003] 1. When laminating by catching the outline frame alignment, the outline frame of the touch screen and the liquid crystal module is captured by the jig, and the lamination tolerance is ensured by adjusting the fixed distance between the two sides on the jig, such as figure 1 shown; [0004] 2. When laminating by capturing the ...
