Description

A method for preventing metal pointers from accidentally touching the bright screen of a smart watch

technical field

The invention relates to a control method for a smart watch, in particular to a method for causing a metal pointer to cause the smart watch to turn on the screen by mistake.

Background technique

The current smart watches are generally controlled by buttons, and there are also some smart watches with touch function, but because the surface of the watch is mostly glass front, the range that can be touched is very narrow, which also makes the user feel inconvenient in operation and the experience is not good. Due to the direct purchase of some air-touch ICs, and due to the limitation of the touch range and watch hands, the hands of smart watches can only be set to the hour and minute hands. After adding the second hand, the touch feeling is not good, and there is a phenomenon of touch failure. In order to solve the phenomenon of poor touch feeling and touch failure, the applicant used creative work to reasonably arrange the installation of the touch FPC in the previous application, even when using a thicker glass shell or other thicker shells, Touch doesn't work either. Especially for watches with more two or three needles currently used, installing multiple pointers on the pointer shaft will inevitably increase the thickness of the smart watch, and a large-area touch FPC can well solve the technology of increasing air touch question.

However, through testing, it is found that although the distance of air touch is greatly increased, it also brings some negative effects. As shown in Figure 1, 101 is the metal pointer of the smart watch, and 9 is the touch after the area is enlarged. FPC, when the touch PFC takes into account the structure of the installation parts, the outer contour of the position close to the movement cover 6 has a step turning along with the outer contour of the movement cover 6, and the touch FPC The starting position in the clockwise direction is a right-angle shape, when the metal pointer 101 turns to the starting right-angle position of the touch FPC in Figure 1 (A in the figure) and the step turning position in the middle (B in the figure) , touch the FPC to sense a metal pointer that can cause the screen to light up, and the screen will light up.

Contents of the invention

For the above-mentioned technical problems, the present invention proposes the following solutions according to the structure of the touch FPC:

A method for a smart watch to prevent a metal pointer from accidentally touching the bright screen. The smart watch includes a movement main board 3, a touch FPC9, a display screen and at least one metal pointer 101. When the touch FPC9 is triggered, the display screen lights up. screen; the method comprises the steps of:

1) The test records the time T on the dial of the smart watch indicated by the pointer when the display screen is triggered to turn on when the at least one metal pointer rotates;

2) The main board of the movement calculates the moment t=f(T,n) when the at least one metal pointer triggers the bright screen at the same position for the nth time according to the properties of the at least one metal pointer;

3) The core board judges the current state: at the time T and the time t, if the display screen is in the bright screen state, then the display screen remains in the bright screen state; if the display screen is in the off-screen state, then the display screen remains off-screen state.

Further, the metal pointer includes a second hand and a minute hand, t=T+60ns of the second hand, and t=T+3600ns of the minute hand.

At the same time, for a smart watch that can realize multi-touch, a method for preventing a metal pointer from accidentally touching the screen of a smart watch, the smart watch includes a movement main board, a touch FPC9, a display screen and at least one metal pointer 101, when the When the touch FPC9 is triggered, the display screen is bright, and the core main board can identify the multi-touch of the touch FPC; the method includes the following steps:

1) The test records the time T on the dial of the smart watch indicated by the pointer when the display screen is triggered to turn on when the at least one metal pointer rotates;

2) The main board of the movement calculates the moment t=f(T,n) when the at least one metal pointer triggers the bright screen at the same position for the nth time according to the properties of the at least one metal pointer;

3) The main board of the movement judges the contact point of the touch FPC:

When the contact point is 1, the main board of the movement judges the state of the current display screen. At the time T and the time t, if the display screen is in the bright screen state, the display screen remains Bright screen state; if the display screen is in the off-screen state, then the display screen remains in the off-screen state;

When the number of contacts is greater than or equal to 2, the display screen is on.

Further, the metal pointer includes a second hand and a minute hand, t=T+60ns of the second hand, and t=T+3600ns of the minute hand.

Through the above-mentioned shielding method, when the metal pointer rotates to the right-angle position of the starting point of the touch FPC and the step turning position in the middle of the touch FPC in Figure 1, or other positions that cause the touch FPC to be triggered, the touch FPC can sense a positive It can cause the metal pointer of its bright screen to cause the phenomenon of false bright screen.

detailed description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and fully convey the concept of example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided in order to give a thorough understanding of embodiments of the invention. However, those skilled in the art will appreciate that the technical solution of the present invention may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other instances, well-known structures, methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

As shown in Figure 1, the smart watch includes a movement main board, a touch FPC9, a display screen 7 and at least one metal pointer 101. When the touch FPC9 is triggered, the movement main board controls the display screen to turn on.

In actual operation, the user can touch the touch FPC9 outside the glass screen of the smart watch to trigger the touch FPC9, thereby generating a bright screen. However, during the rotation of the metal pointer, since the FPC has a turning point, it is also easy to trigger the touch FPC, such as position A and position B in Figure 1 . Although there may be turning points, these turning points are not necessarily the turning points that will be triggered by touching the FPC when the metal pointer rotates. Therefore, it is necessary to verify by experiment.

First, the test records the time T on the dial of the smart watch indicated by the pointer when the display screen is triggered to turn on when the metal pointer rotates. During the test, multiple verifications are required. If the metal pointer rotates 10 times, 8 of which will cause the screen to turn on, then this position (the position at time T) is considered to be the position that causes the trigger; moreover, when the metal pointer rotates once, There may be multiple time Ts (for example, positions A and B in Fig. 1 correspond to a time T respectively). (Generally, the hour hand is relatively short, and it will not enter the range that causes the touch FPC to trigger when rotating)

Secondly, according to the type of the metal pointer, calculate the time t=f(T, n) when the metal pointer reaches the position periodically, for example, when the metal pointer is the second hand, t=T+60ns; when the metal pointer is the minute hand, t =T+3600ns.

Then, shield the trigger generated by the metal pointer when passing through this position. The core main board includes a processor, and the core main board judges the current state: at the time t (n=0, 1, 2, 3...), if the display screen is in the bright screen state, then The display screen remains in a bright screen state; if the display screen is in an off screen state, then the display screen remains in an off screen state. Specifically, the main board of the movement or the processor of the main board of the movement does not perform any processing on any triggers generated by the metal pointer passing through the position (such as position A and position B). When the screen is already on, when the metal pointer When passing position A, if there is 1 second left for the screen to turn on (assuming a total of 3 seconds to turn on the screen), continue to turn on the screen and turn off the screen after 1 second;

Further, when the touch FPC is a touch FPC capable of multi-touch, and the motherboard chip or processor can perform calculations on multi-touch, whether the display screen is bright or not in the above "then" Before judging the state of the screen and the information screen, first judge the number of contacts (points that can cause the touch FPC to be triggered). When the contact is 1, the main board of the movement judges the state of the current display. At said time t (n=0, 1, 2, 3...), if the display screen is in the bright screen state, then the display screen remains in the bright screen state; if the display screen is in the off-screen state, Then the display screen remains in the off-screen state; when the contact points are greater than or equal to 2, the display screen is turned on. That is, when the number of contacts is greater than 2, the situation of triggering the bright screen caused by a metal pointer must be excluded.

Through the above-mentioned shielding method, when the metal pointer rotates to the right-angle position of the starting point of the touch FPC and the step turning position in the middle of the touch FPC in Figure 1, or other positions that cause the touch FPC to be triggered, the touch FPC can sense a positive It can cause the metal pointer of its bright screen to cause the phenomenon of false bright screen.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
