[0002] With the development of Internet technology and intelligent products, a variety of intelligent wearable products have appeared on the market. These products are used to implement various detection and monitoring functions and integrate with the Internet to achieve intelligence. Unlike traditional rings, smart rings have different electronic functions and can be flexibly designed according to needs. Common smart rings integrate flexible circuit boards and various sensors inside the rings, which can monitor various human vital signs. Smart rings are very powerful. However, because smart rings are worn on the human finger, the space inside the ring is extremely limited. Therefore, the electrical components inside the ring must be integrated and miniaturized as much as possible. In terms of batteries, they can only use small batteries with low energy storage.

[0003] While low-energy storage batteries prioritize their battery life, they no longer have redundant power to supply high-energy consumption devices. Therefore, it is difficult to see smart rings with displays in the products currently on the market. The reason is that traditional display devices consume too much power, and the low-energy storage batteries of smart rings cannot meet the usage requirements. However, without a display, many prompt functions of smart rings cannot be directly displayed on the smart ring itself, but need to be read through the accompanying APP client, which brings great inconvenience to users.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6A low-power display mechanism applied to a low-energy storage device includes a circuit board assembly 3, a battery 4, and a low-power display screen 5. The battery 4 and the low-power display screen 5 are both electrically connected to the circuit board assembly 3. The low-power display screen 5 includes a top transparent electrode layer 51, a color particle layer 52, and a bottom electrode layer 53. The color particle layer 52 is sandwiched between the top transparent electrode layer 51 and the bottom electrode layer 53. The top transparent electrode layer 51 is usually made of a transparent conductive material such as ITO (indium tin oxide) and serves as a common electrode to cover the entire display area. The bottom electrode layer 53 is a segmented electrode layer. The display content is formed by a plurality of electrodes 6 arranged in a predefined segment shape. Each segment electrode 6 can be independently controlled. When a segment code electrode layer is used, the resolution of the display content is determined by the predefined number of segments. Usually, the resolution is low. At the same time, due to the small number of control units, the power consumption of the segment code electrode layer is also low. The bottom electrode layer 53 can also use a dot matrix electrode layer. The dot matrix electrode layer includes a TFT substrate layer that plays a supporting role and a thin film transistor layer covering the TFT substrate layer. The TFT substrate layer has a plurality of pixel electrodes 6 arranged in a dot matrix. Each pixel electrode 6 is connected to a corresponding transistor. The display content is formed by controlling the transistor matrix. The resolution of the dot matrix electrode layer can be very high, which depends on the density of the pixel electrode 6. At the same time, the power consumption is higher than that of the segment code electrode layer. The bottom electrode layer 53 can be a hard pad layer or a soft pad layer. When the soft pad layer is used, the low-power display screen 5 can be suitable for use in various curved display areas, which improves its applicability. The color particle layer 52 is arranged with a plurality of color particles. The color particles are self-charged. The color particles include positively charged color particles 54 and negatively charged color particles 55. The colors of the positively charged color particles 54 and the negatively charged color particles 55 are different. When the top transparent electrode layer 51 and the bottom transparent electrode layer 52 are connected, the color of the positively charged color particles 54 and the negatively charged color particles 55 are different. When an electric field is applied to the interlayer region between the upper and lower electrode layers 53, the color-forming particles are driven by the electric field to move in the direction of the corresponding opposite electric field. Driven by the control chip built into the circuit board assembly 3, the top transparent electrode layer 51 and the bottom electrode layer 53 can form a patterned electric field identical to the display content layout. Under the guidance of the patterned electric field, the color-forming particles gather to form the target display content and display it to the user through the top transparent electrode layer 51. Specifically, in the display device, when content needs to be displayed, by controlling the electric field between the upper transparent electrode and the lower electrode, the color-forming particles move to the corresponding position under the action of the electric field to form the required image or text. When the electric field is turned off or the power is cut off, the color-forming particles maintain their position unchanged due to the hysteresis effect of the liquid, so the displayed content does not disappear. Even if the device is powered off, the content remains visible until the content changes when the electric field is applied next time.

[0026] In the first embodiment, the color particle layer 52 is filled with a transparent liquid, and the color particles are suspended in the transparent liquid of the color particle layer (52). If the top transparent electrode layer 51 is positively charged and the bottom electrode layer 53 is negatively charged, the positively charged color particles 54 are white and the negatively charged color particles 55 are black. At this time, the black particles will float up and the white particles will sink, forming a black display at the top transparent electrode layer 51. Conversely, if the top transparent electrode layer 51 is negatively charged and the bottom electrode layer 53 is positively charged, the white particles will float up and the black particles will sink, forming a white display at the top transparent electrode layer 51.

[0027] Since the transparent liquid has a bistable characteristic, namely the hysteresis effect, when the electric field between the top transparent electrode layer 51 and the bottom electrode layer 53 disappears, the display particles will maintain their orientation and be suspended at the position at the moment the electric field disappears. Therefore, the display content seen outside the top transparent electrode layer 51 will also remain unchanged.

[0028] In the second embodiment, the color-developing particle layer 52 is filled with a plurality of particle shells 56 , which are transparent shells. The color-developing particles are wrapped in the particle shells 56 , and positively charged color-developing particles 54 and negatively charged color-developing particles 55 coexist in the particle shells 56 . The positively charged color-developing particles 54 and negatively charged color-developing particles 55 are suspended in the transparent liquid in the particle shells 56 .

[0029] If the top transparent electrode layer 51 is positively charged and the bottom electrode layer 53 is negatively charged, the positively charged color-developing particles 54 are white and the negatively charged color-developing particles 55 are black. At this time, the black particles float up and gather at the upper end of the particle shell 36, while the white particles sink and gather at the lower end of the particle shell 36, forming a black display at the top transparent electrode layer 51. Conversely, if the top transparent electrode layer 51 is negatively charged and the bottom electrode layer 53 is positively charged, the white particles float up and gather at the upper end of the particle shell 36, while the black particles sink and gather at the lower end of the particle shell 36, forming a white display at the top transparent electrode layer 51.

[0030] Since the transparent liquid has a bistable characteristic, namely the hysteresis effect, when the electric field between the top transparent electrode layer 51 and the bottom electrode layer 53 disappears, the display particles will maintain their orientation and be suspended at the position at the moment the electric field disappears. Therefore, the display content seen outside the top transparent electrode layer 51 will also remain unchanged.

[0031] In embodiment three, the color-developing particle layer 52 is filled with a transparent liquid, and the color-developing particles are formed by positively charged color-developing particles 54 and negatively charged color-developing particles 55 connected as one body. One side of the color-developing particles is the positively charged color-developing particles 54, and the opposite side is the negatively charged color-developing particles 55. The color-developing particles are suspended in the transparent liquid of the color-developing particle layer 52.

[0032] If the top transparent electrode layer 51 is positively charged and the bottom electrode layer 53 is negatively charged, the positively charged color-developing particles 54 are white and the negatively charged color-developing particles 55 are black. At this time, the black end of the color-developing particle rotates toward the top transparent electrode layer 51 until it faces the top transparent electrode layer 51, and the white end of the color-developing particle rotates toward the bottom electrode layer 53 until it faces the bottom electrode layer 53, forming a black display at the top transparent electrode layer 51. Conversely, if the top transparent electrode layer 51 is negatively charged and the bottom electrode layer 53 is positively charged, the white end of the color-developing particle rotates toward the top transparent electrode layer 51 and the black end of the color-developing particle rotates toward the bottom electrode layer 53, forming a white display at the top transparent electrode layer 51.

[0033] Since the transparent liquid has a bistable characteristic, namely the hysteresis effect, when the electric field between the top transparent electrode layer 51 and the bottom electrode layer 53 disappears, the display particles will maintain their orientation and be suspended at the position at the moment the electric field disappears. Therefore, the display content seen outside the top transparent electrode layer 51 will also remain unchanged.

[0034] In the technical solution of this application, the color-developing particles are suspended in a liquid with a hysteresis effect and can move to the corresponding position under the action of an external electric field to form the desired display content. When the electric field disappears, the hysteresis effect of the liquid can keep the color-developing particles in place, so the display content can be maintained for a long time and remains clearly visible even after the device is powered off. This design significantly reduces energy consumption by reducing the frequent application of electric fields and is particularly suitable for low-energy storage devices such as smart rings, smart bracelets, and smart glasses.

[0035] When the low-power display mechanism is applied to a low-energy storage device smart ring, the smart ring includes a shell 1, a perspective window 11 is provided on the shell 1, the low-power display screen 5 is provided at the perspective window 11, the circuit board assembly 3 and the battery 4 are provided on the inner side of the shell 1, the circuit board assembly 3 includes a flexible circuit board 31, a charging interface 32 and electronic components 33 are encapsulated on the flexible circuit board 31, a potting layer 2 is provided on the inner side of the shell 1, the circuit board assembly 3, the battery 4 and the low-power display screen 5 are all encapsulated in the potting layer 2, the charging interface 32 Extending out from the potting glue layer 2, the low-power display screen 5 displays corresponding content according to the control instructions under the control of the built-in control chip of the smart ring circuit board assembly 3. The displayed content is presented to the user from the perspective window 11 on the shell 1. The control circuit can be set to intermittently switch the displayed content through software. Since the low-power display screen 5 consumes power only at the moment of switching the displayed content and does not consume power when in standby mode, the intermittent mode is used to switch the display, so that its power consumption becomes very low. The charging interface 32 can charge the battery 4 to supplement power when connected to an external power supply using a charging cable.

[0036] To sum up: In the present invention, the low-power display screen 5 consumes electrical energy only when the display content is changed, and the displayed content can be maintained for a long time and will not disappear even if the power is cut off. In addition, the displayed content can be clearly seen even under strong light. This design significantly reduces energy consumption by reducing the frequent application of electric fields and is suitable for use in various low-energy storage devices.
