Fig. 2 is a flowchart of a second embodiment of the present invention.

Embodiments of the invention

Example embodiments will now be described more fully with reference to the drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the examples set forth herein; on the contrary, providing these embodiments makes the present invention more comprehensive and complete, and fully conveys the concept of the example embodiments For those skilled in the art. The drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repeated description will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to give a full understanding of the embodiments of the invention. However, those skilled in the art will realize that the technical solutions of the present invention may be practiced without omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be used. In other instances, well-known structures, methods, devices, implementations or operations have not been shown or described in detail to avoid obscuring the subject and obscuring aspects of the invention.

Example 1.

As shown in FIG. 1, the smart watch includes first and second screens. A second screen is provided outside the first screen of the original smart watch, and the observer can see the first screen through the second screen.

The first screen and the second screen are controlled by the control unit.

During normal use, the first screen displays the content, and the second screen is in a power-off state. The observer can view the content displayed on the first screen through the second screen.

The watch includes a judgment unit, which is connected to the control unit and can judge the display state of the first screen. The display status includes bright screen and off screen status.

The second screen is displayed in response to the judgment result of the judgment unit.

Example 2.

As shown in FIG. 2, when the first screen is in a bright state, the judgment unit feeds back a first judgment value to the control unit, and the control unit controls the second screen 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 control unit. The control unit drives the second screen to be powered on based on the second judgment value.

The second screen is a transparent screen in the power-off state. When the power is turned on, the control unit drives the second screen to perform a pure color display (no need to display text messages, incoming calls, weather, etc. like the first screen). The color of the solid color display is preset, and the basis for setting is the color of the watch frame. If the watch frame is golden, the solid color setting can be golden.

In general, the color of the solid color display is more or less different from the color of the watch frame. Therefore, when setting the color of the solid color of the second screen, the upper and lower errors of the three parameters of the RBG are controlled within 20.

Example 3.

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 judgment unit and the measurement result of the light sensor.

The control unit stores a brightness threshold, and when the brightness measured by the light sensor is greater than or equal to the brightness threshold, the control unit drives the second screen to be powered on based on the second judgment value; when the light sensor measures When the brightness threshold of is less than the brightness threshold, the control unit drives the second screen to power off based on the second judgment value.

Example 4.

Under different lighting brightness conditions, the user's visual experience is different. Therefore, multiple brightness thresholds can be stored in the control unit. The specific scheme is as follows.

For example, three brightness thresholds Q ₁ <Q ₂ <Q _{3 are} stored, and if the brightness threshold measured by the light sensor is less than Q ₁ , the control unit controls the second screen to be powered off.

If the brightness threshold measured by the light sensor is between Q ₁ and Q ₂ , the control unit controls the second screen to be powered on, and controls the brightness of the second screen to be Q ₁ .

If the brightness threshold measured by the light sensor is greater than Q ₃ , the control unit controls the second screen to be powered on, and controls the brightness of the second screen to be Q ₃ .

In this way, under the same light intensity, the colors of the viewer's viewing screen and the frame tend to be consistent.

Example 5.

In many cases, the color displayed on the screen is not as natural as the color displayed by the frame. Therefore, it is expected that there will be a more natural color display method that makes the color of the screen and the frame tend to be consistent and more natural. Thus, the display method of Example 4 is optimized.

The control unit includes an image processing unit, and when the control unit controls the brightness value of the second screen to the i-th brightness value, the image processing unit divides the second screen of the smart watch from the center to the edge There are 1-M total M areas, where the first area is the center of the second screen, the Mth area is the area where the second screen is in contact with the watch frame of the smart watch, and the image processing The unit divides the i-th luminance value into M luminance scores from small to large, the smallest luminance score Q ₁ is 0, and the largest luminance score Q _M is the i-th luminance value; the control unit controls the A th luminance value The (1<=A<=M) area displays the A-th luminance score Q _A among the M luminance scores.

Further, the second screen is an LED screen.

In this way, from the center to the edge to the watch frame, there is a color gradual effect, making the surface and the watch frame look like one.
