DETAILED DESCRIPTION

[0024] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0025] Referring to FIG. 1-6, a 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 electrically connected with the circuit board assembly 3, the low-power display screen 5 includes a top transparent electrode layer 51, a color developing particle layer 52 and a bottom electrode layer 53, the color developing 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 ITO (indium tin oxide) or other transparent conductive material, as a common electrode, covering the entire display area, the bottom electrode layer 53 applies a segment code electrode layer, the segment code electrode layer is formed by a plurality of electrodes 6 arranged in a predefined segment to form display content, each segment electrode 6 can be independently controlled, when the segment code electrode layer is applied, the resolution of the display content is determined by the predefined segment number, usually the resolution is low, at the same time, due to the fewer control units, the power consumption of the segment code electrode layer is also low; the bottom electrode layer 53 can also apply 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 that is overlaid on the TFT substrate layer, a plurality of pixel electrodes 6 are arranged in a dot matrix on the TFT substrate layer, each pixel electrode 6 is correspondingly connected with a transistor, the display content is formed by controlling the transistor matrix, the resolution of the dot matrix electrode layer can be very high, depending on the density of the pixel electrodes 6, at the same time, the power consumption is relatively high compared with the segment code electrode layer, the bottom electrode layer 53 can be a hard gasket layer or a soft gasket layer, when the soft gasket layer is applied, the low-power display screen 5 can be applied to various curved display areas, improving its applicability, the color developing particle layer 52 is arranged with a plurality of color developing particles, the color developing particles have self-charges, the color developing particles include positive charge color developing particles 54 and negative charge color developing particles 55, the colors of the positive charge color developing particles 54 and the negative charge color developing particles 55 are different, when an electric field is applied between the top transparent electrode layer 51 and the bottom electrode layer 53, the color developing particles are driven by the electric field to move towards the corresponding opposite electric field direction, the top transparent electrode layer 51 and the bottom electrode layer 53 can form the same layout type electric field as the display content layout under the driving of the control chip built in the circuit board assembly 3, the color developing particles are guided by the layout type electric field to gather to form the target display content and show to the user through the top transparent electrode layer 51, specifically, in the display device, when the display content is needed, the color developing particles move to the corresponding position under the action of the electric field between the upper transparent electrode and the lower electrode, forming the required image or text. When the electric field is turned off or powered off, the color developing particles remain in their positions under the action of the magnetic hysteresis effect of the liquid, so the display content will not disappear. Even if the device is powered off, the content is still visible until the next time the electric field acts to change the content.

[0026] In the first embodiment, the color-developing particle layer 52 is filled with a transparent liquid, and the color-developing particles are suspended in the transparent liquid in the color-developing 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-developing particles 54 are white, and the negatively charged color-developing particles 55 are black. At this time, the black particles float upwards, and the white particles sink downwards, so that a black display is formed 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 upwards, and the black particles sink downwards, so that a white display is formed at the top transparent electrode layer 51.

[0027] Since the transparent liquid has a bistable characteristic, i.e., a hysteresis effect, when the electric field between the top transparent electrode layer 51 and the bottom electrode layer 53 disappears, the display particles also remain suspended at the position at the moment when the electric field disappears, so that the display content seen outside the top transparent electrode layer 51 remains unchanged.

[0028] In the second embodiment, the color-developing particle layer 52 is filled with a plurality of particle shells 56, the particle shells 56 are transparent shells, the color-developing particles are wrapped in the particle shells 56, and the positively charged color-developing particles 54 and the negatively charged color-developing particles 55 coexist in the particle shells 56, and the positively charged color-developing particles 54 and the 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 upwards and gather at the upper end of the particle shell 36, and the white particles sink downwards and gather at the lower end of the particle shell 36, so that a black display is formed 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 upwards and gather at the upper end of the particle shell 36, and the black particles sink downwards and gather at the lower end of the particle shell 36, so that a white display is formed at the top transparent electrode layer 51.

[0030] Since the transparent liquid has a bistable characteristic, i.e., a hysteresis effect, when the electric field between the top transparent electrode layer 51 and the bottom electrode layer 53 disappears, the display particles also remain suspended at the position at the moment when the electric field disappears, so that the display content seen outside the top transparent electrode layer 51 remains unchanged.

[0031] In the third embodiment, the color-developing particle layer 52 is filled with a transparent liquid, and the color-developing particles are integrally connected by the positively charged color-developing particles 54 and the negatively charged color-developing particles 55. 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 in the color-developing particle layer 52.

[0032] If the top transparent electrode layer 51 is positively charged, 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 particles rotates towards the side of the top transparent electrode layer 51 until it faces the top transparent electrode layer 51, and the white end of the color developing particles rotates towards the side of the bottom electrode layer 53 until it faces the bottom electrode layer 53, thus forming a black display at the top transparent electrode layer 51. Conversely, if the top transparent electrode layer 51 is negatively charged, the bottom electrode layer 53 is positively charged, the white end of the color developing particles rotates towards the side of the top transparent electrode layer 51, and the black end of the color developing particles rotates towards the side of the bottom electrode layer 53, thus forming a white display at the top transparent electrode layer 51.

[0033] Since the transparent liquid has a bistable characteristic, i.e. hysteresis effect, when the electric field between the top transparent electrode layer 51 and the bottom electrode layer 53 disappears, the display particles also remain in the position at the moment of disappearance of the electric field, thus the display content seen outside the top transparent electrode layer 51 remains unchanged.

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

[0035] When the low-power display mechanism is applied to a low-energy storage device smart ring, the smart ring comprises a shell 1, a see-through window 11 is arranged on the shell 1, a low-power display screen 5 is arranged at the see-through window 11, a circuit board assembly 3 and a battery 4 are arranged on the inner side of the shell 1, the circuit board assembly 3 comprises a flexible circuit board 31, a charging interface 32 and electronic components 33 are packaged on the flexible circuit board 31, a potting adhesive layer 2 is arranged 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 packaged in the potting adhesive layer 2, the charging interface 32 extends out of the potting adhesive layer 2, the low-power display screen 5 displays the corresponding content under the control of the control chip built-in the smart ring circuit board assembly 3 according to the control instruction, and the display content is displayed to the user from the see-through window 11 on the shell 1, and the display content can be switched intermittently by software setting control circuit, since the low-power display screen 5 only consumes power at the moment of switching display content, and does not consume power in standby mode, the display is switched in intermittent mode, so that the power consumption is very low, and the charging interface 32 can charge the battery 4 when an external power supply is connected to the charging interface 32 using a charging line.

[0036] In summary: the utility model discloses, low -power consumption display screen 5 only needs to consume electric energy when changing display content, and the content can be kept for a long time, even if power failure also can not disappear, and under strong light can make display content clear and visible, this design reduces the energy consumption through reducing frequent electric field application, significantly, is suitable for being applied to various low energy storage device and uses.
