Problems solved by technology

The optical filters in the existing mobile phone cameras are all glued to the bracket of the camera module by glue. The process of adhering the optical filters is time-consuming and laborious, and the cost is high. If the glue is used for a long time, it will age, and the filter will fall off from the bracket; in order to overcome the above problems, some lens manufacturers have their own filter on the lens, thus eliminating the need to stick the filter when the camera module is assembled. However, setting the optical filter in the lens requires high lens processing requirements, which leads to a decrease in the production efficiency of the lens manufacturer, which in turn increases the cost. Therefore, the shipment of the optical filter in the lens is very small.
[0004] In addition, both TP and CCM are independent module components. During the assembly process of mobile phones, the production steps are cumbersome, which is not conducive to reducing costs.

Abstract

The invention provides a touch screen and shooting module integrated apparatus. The apparatus comprises a touch screen and a shooting module electrically connected with the touch screen. The touch screen comprises a panel and a touch control soft circuit board, wherein the panel is provided with a light transmission area and a light shading area, the light shading area is coated with a decorative layer, and the decorative layer is provided with a light transmission hole; the shooting module. The shooting module comprises a front shooting module arranged to be right opposite to the light transmission hole, wherein the front shooting module comprises a front lens, a front optical filter and a front lens soft circuit board; the front lens soft circuit board and the touch control soft circuit board are integrated on the same soft circuit board; the front optical filter is formed on the decorative layer; and the front optical filter is arranged to be right opposite to the light transmission hole. According to the invention, the touch control soft circuit board and the front lens soft circuit board are arranged to be integrated through an FPC so that the two share one connector, space is saved for the mainboard of a mobile electronic device such as a mobile phone and the like, and the assembling is facilitated; and the front optical filter can be directly formed on the decorative layer, and compared to the prior art, the production efficiency is saved, and the production cost is lowered.

Description

technical field [0001] The invention relates to touch camera technology, in particular to a touch screen and camera module integration device. Background technique [0002] Touch screen (Touch panel, hereinafter referred to as TP) and camera module (CMOS Camera Module, hereinafter referred to as CCM) are essential accessories for mobile electronic devices such as mobile phones, electronic watches, tablet computers, super notebooks, and mobile electronic devices at least The deployment of two CCMs has driven the rapid development of these electronic devices, especially with the advent of smartphones and tablets and consumer demand for continued reductions in overall costs. However, it is necessary to make electronic equipment develop towards the trend of lightness and thinness, so it is necessary to provide a module device integrating TP and CCM. [0003] While reducing the cost of electronic equipment, the thickness of electronic equipment cannot be increased, and even the ...
