Description
Technical Field
The invention relates to the technical field of intelligent watches, in particular to an intelligent watch and an accurate touch method thereof.
Background
With the development of technology, more and more people are beginning to use wearable devices such as smartwatches. The smart watch is not only a watch, but also can realize various powerful functions through software support, data interaction and cloud interaction. The type of smart wrist-watch is diversified, and wherein, the smart wrist-watch that combines together traditional metal pointer and touch-sensitive screen is ready for consumer's favor.
With the development of wearable electronic devices, smart watches with both traditional metal pointers and touch display components have become a hot development trend of wearable devices. For the smart watch with the metal pointer and the touch display module, the metal pointer may interfere with the touch performance of the touch display module, and in order to eliminate the influence, the current smart watch with the metal pointer generally adopts the following two ways to realize touch operation:
in the first scheme, the touch display component is designed in a way that a touch screen and a display screen are separated (for example, LG, WATCH, W7 series products, and patent document with publication number US20170261940 A1). Wherein, the touch-sensitive screen sets up on the apron of intelligent wrist-watch table body, and the display screen setting is in the table body, and touch-sensitive screen and display screen pass through the flexible circuit board and connect. The metal pointer is arranged between the touch screen and the display screen. In this way, normal use of touch, display and metal pointers is considered.
In the second scheme, a transparent touch display component is disposed above the pointer (for example, application No. 201420718481.X, and application No. US20150078144 A1). In this way, the metal pointer can be exposed to the outside through the transparent display screen, and the interference of the metal pointer to the touch display component is avoided.
However, the touch display module and the display screen of the first scheme are difficult to assemble, the transparent touch display module of the second scheme is high in production cost, and when the touch screen and the display screen are combined and matched with an intelligent watch with pointers, due to the coexistence of the pointers and the display screen, the touch precision can be influenced to a certain extent by directly operating the display screen, and further, the main reason for influencing the touch precision is that the capacitance screen depends on capacitance change to realize the influence of coordinate determination, and once a finger is infected with water or a screen is infected with water or other non-touch objects influence the capacitance, the touch precision can be influenced.
Therefore, the accurate touch intelligent watch and the accurate touch method thereof are provided, wherein the pointer of the non-capacitive screen and the display screen coexist.
