Embodiment Construction

[0022] As mentioned in the background section, the integrated touch module and touch display device formed by the existing full lamination technology are prone to display macular problems.

[0023] The existing method of forming an integrated touch module includes: first attaching a polarizer and a lower polarizer to the upper and lower surfaces of the LCD box; then installing a backlight on the surface of the lower polarizer to form an LCD module; The LCD module is fully bonded to the touch screen to form an integrated touch module.

[0024] The inventors found that since the upper and lower surfaces of the LCD box are glass substrates, and since the thermal expansion rate and shrinkage rate of the glass are different from those of the polarizer, the process of attaching the polarizer to the upper and lower surfaces of the LCD box , Affected by the temperature and humidity of the outside world, due to the different degrees of expansion or contraction of the glass and the pola...

Abstract

The invention provides a manufacturing method of an integrated touch control module. The method comprises the following steps of: arranging a first polaroid on the back surface of a touch screen; arranging a liquid crystal display device on the surface, which is deviated from the touch screen, of the first polaroid; arranging a second polaroid on surface, which is deviated from the touch screen, of the liquid crystal display device; and arranging a backlight source on the surface, which is deviated from the liquid crystal display device, of the second polaroid to form the integrated touch module. According to the manufacturing method of the integrated touch control module provided by the invention, the liquid crystal display device can be fully jointed with the touch screen in a relatively flat state in the manufacturing process of the integrated touch module, and the problem of poor flatness between the liquid crystal display device and the touch screen is solved; and on the other hand, the influence of the problem of poor flatness of the backlight source on the display effect of the integrated touch control module can be eliminated, and the problem of displaying of yellow spots on the integrated touch control module is solved on two aspects.

Description

technical field [0001] The invention belongs to the technical field of electronic appliances, and in particular relates to an integrated touch module, a manufacturing method thereof, and a touch display device. Background technique [0002] With the increasing number of multimedia information query devices, touch screens, as a touch display device, have begun to become an integral part of multimedia information query devices. As a simple, convenient and natural input device, it is widely used in various portable devices, such as mobile phones, PDA (Personal Digital Assistant, personal digital assistant) and so on. [0003] At present, the touch display devices of mid-to-high-end products of smart phones are basically made of full lamination technology. Liquid crystal display device) is fully bonded through optical glue, and the optical performance of the touch display device formed by the full bonding technology is better. [0004] However, touch display devices manufactur...
