Description

smart watch

Technical field

The present invention relates to a smart watch, in particular to a smart watch which makes the screen color tend to the frame.

Background technique

Watches are becoming more and more fashionable products. Wearing watches just shows the time and cannot meet the needs of users. Smart watches came into being. Smart watches generally have a screen that can be powered on, and users can perform interactive operations through this screen. In idle time (that is, when the user is not viewing the contents of the watch), the screen is generally completely black due to power failure. For a smart watch with a black frame, the whole watch looks like one, with excellent visual effects. CN1990820A discloses an electrochromic film. The prior art provides a point color film that can achieve the electrochromic effect by using a single transparent substrate. CN107144980A discloses a sunglasses system based on Bluetooth control, which involves the miniaturization of electrochromic applications (applied to glasses). Electrochromic materials have bistable performance. Electrochromic display devices made of electrochromic materials do not require a backlight, and after displaying a static image, as long as the display content does not change, it will not consume electricity. The purpose of energy saving. By using different redox materials, the display screen can display different colors.

technical problem

In the era of highlighting individuality, the choice of color varies from person to person, and the color of the bezel is no longer limited to black. Therefore, it is expected that certain measures should be taken to make the color of the screen consistent with the color of the bezel when the screen is turned off and black. Technical issues.

Technical solutions

In view of the above technical problems, the present invention provides a smart watch that can activate the secondary screen when the main screen is powered off, and display the same color as the watch frame through the secondary screen, so that the whole watch looks The overall color is basically the same.

The technical scheme of the present invention is as follows:

A smart watch, the smart watch includes:

First screen

A first control unit, the control unit can control the first screen;

The second screen and the second control unit;

A judging unit, which is connected to the second control unit and can judge the display state of the first screen;

The second control unit may control the second screen to display in response to the judgment result of the judgment unit.

Further, the second screen is configured such that: the second screen is in a transparent state when it is not powered on; the second screen is in a position farther from the control unit than the first screen, so that the observer can see through the transparent state. The first screen can only be seen by the second screen; the second screen is made of electro-glass material, and the electro-glass material includes a base, a transparent conductive layer, an electrochromic layer, an electrolyte layer and an ion storage layer; The second control unit also includes an electrochromic control module and an electric field control module.

Further, when the first screen is in a bright screen state, the judgment unit feeds back a first judgment value to the second control unit, and the second control unit controls the second control unit based on the first judgment value. The screen is powered off; when the first screen is off, the judgment unit feeds back a second judgment value to the second control unit; the second control unit drives the electric field based on the second judgment value The control module sends electric field parameters to the electrochromic control module, and the electrochromic control module controls the second screen to change color.

Further, the second screen is displayed in a pure color under the action of the electric field control module, and the color displayed in the pure color is consistent or substantially consistent with the color of the bezel. By setting different glass material contents, the electrochromic color can be changed.

Further, the smart watch further includes a light sensor connected to the control unit; the second screen displays in response to the judgment result of the second judgment unit and the measurement result of the light sensor.

Further, the second control unit stores N electric field parameters ranging from small to large, E _i ,1<=i<=N, where E ₁ <E ₂ <...<E _N , the N a parameter input to the electrical field after electrochromic control module, the electrochromic control module controls the second screen color screen brightness parameter values corresponding to each Q _i is the luminance threshold N, 1 <= i <= N , _{_{wherein, Q 1 <Q 2 <......}} <Q N, the second control unit stores said N luminance threshold Q _i,

When the brightness Q measured by the light sensor is less than the minimum brightness threshold Q ₁ stored by the control unit, the second control unit controls the second screen to power off;

When the luminance of the light sensor is measured Q _{_{Q i <= Q <Q i}} + _1, the second control unit controls the electric field control module outputs the electric field corresponding parameter Q _I E _i to the electrical electrochromic control module, the electrochromic control module controls the second brightness of the second screen and the screen color value Q _i;

When the brightness of the light sensor is greater than the measured Q Q _N, the second control unit controls the electric field control module outputs the electric field corresponding parameters Q _N E _N electrochromic to the control module, the electrical The color change control module controls the second screen to change color and the brightness value of the second screen is Q _N.

Beneficial effect

Through the above technical solution, the watch is in the off-screen state, and when the user sees the watch, he can still see the whole watch with the color integrated with the watch frame or the watch with gradual color.
