Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] see image 3 , Figure 4 and Figure 8 , the method for controlling the thickness consistency of the capacitive touch screen provided by the present invention, such as image 3 As shown, on any one of the upper substrate or the lower substrate, such as the upper substrate 11, an adhesive, i.e. glue 12, is dripped by a glue dispenser 32; then on any substrate, such as still on the upper substrate 11 , through the nozzle 41, the spacer 42 is sprayed onto the upper substrate 11 with a gas of a certain pressure, and the spacer 42 is dispersed on the substrate. The aforementioned spacer can be...

Abstract

The invention provides a capacitive touch screen and a control method of thickness consistency thereof. The touch screen comprises an upper substrate and a lower substrate which are adhered together through an adhering agent, wherein the adhering agent contains a spacing agent with particle diameter between 2mum and 2mm. The control method sequentially comprises the steps of: adding the adhering agent and the spacing agent on the upper substrate or on the surface of the lower substrate with a flexible circuit board; then adhering the upper substrate and the lower substrate together and ensuring that glue is dispersed and leveled to fill in the adhering surface of the upper substrate and the lower substrate; and curing and preparing the capacitive touch screen, wherein the spacing agent can be firstly dissolved in the solution and can also be directly sprayed on the surface of substrate subjected to dipping the glue, and the spacing agent is mixed with the glue and then dripped or printed on the surface of the substrate. Because of adding the spacing agent with selective particle shape and diameter, the flatness of the two substrates of the touch screen is controlled within not more than + / -1mum, the gap of the two substrates is controlled between 2mum and 2mm, and the thickness consistence of the touch screen can be controlled within not more than + / -0.05mm.

Description

technical field [0001] The invention relates to a capacitive touch screen and a manufacturing method of the capacitive touch screen, in particular to a method for controlling the thickness consistency of the capacitive touch screen. Background technique [0002] The touch screen can be used as an interface tool for operating electronic devices through the display screen, allowing users to input information directly on the surface of the display device with a touch screen by touching or handwriting, which is more friendly and convenient than input devices such as mice and keyboards. Therefore, it is more and more widely used in various portable devices, such as mobile phones, PDAs and so on. For example, a user may input desired information on a display device that is displaying an image and is combined with a touch screen. [0003] According to the type of contact object used (such as fingers, pens, etc.) and the way of confirming the contact (the position where the contact...
