Description

Technical Field

[0001] The present invention relates to the field of electronic display technology, and in particular to a dual-contact multi-level driven electronic paper nail art and a control method thereof. Background Art

[0002] The nail art method used in the nail art industry is fixed color or fixed pattern. If you want to change the color of the nail art or change a different pattern, you need to put on and re-apply the nail art. In this way, the process of putting on the nail art will become complicated and waste more time. At the same time, frequent changes of nail art will also damage the nail body.

[0003] In the prior art, electronic manicures have emerged, which can change a variety of colors according to personal preferences without removing the nails, eliminating the damage to the fingernails caused by putting on and taking off the nails every time the color and pattern are changed. However, existing electronic manicures, such as Chinese patent CN119523243A, describe an electronic paper manicure solution using three metal contacts. The first PIN pin is connected to the common electrode, and the second and third PIN pins are connected to the positive and negative poles of the driving electrode respectively. Three physical contact points are required to achieve dual-level control. The multiple contacts bring about the problems of bloated structure and a high probability of poor contact. Summary of the Invention

[0004] The present invention is made in view of the above-mentioned problems, and its purpose is to provide an electronic paper nail art with dual-contact multi-level drive, which replaces the traditional positive / negative dual contacts by inputting multi-level timing signals through a single contact, and optimizes three fixed contacts to two contacts, thereby reducing the required width of the electronic nail art, improving the aesthetics, and reducing the risk of poor contact of the contacts. The electronic paper layer is controlled by the difference between the timing drive signal of the second contact and the reference voltage, supporting richer color gradients.

[0005] Specifically, a first aspect of the present invention provides a dual-contact multi-level driven electronic paper nail art, comprising: a transparent cover; An electronic paper layer is provided on the lower end surface of the transparent cover; A driving electrode layer is provided on the lower end surface of the electronic paper layer and is electrically connected to the electronic paper layer; Two metal contacts, a first contact electrically connected to a reference level end of the driving electrode layer, for inputting a constant reference level; The second contact is electrically connected to the signal input end of the driving electrode layer and is used for inputting a timing driving signal including multiple levels.

[0006] The first contact is constantly connected to a reference voltage to provide an electric field reference anchor point; the second contact input includes a multi-level timing drive signal to form a dynamic electric field through a voltage difference.

[0007] Furthermore, the electronic paper layer is a color display execution layer that displays different colors based on the movement of charged particles.

[0008] Electronic paper contains charged color particles, whose movement is controlled by the direction and strength of the electric field between two electrodes. The direction of the electric field determines the direction of particle movement (floating / sinking), and the electric field strength determines the distance the particles move (the depth of color). The present invention adjusts the second contact voltage to form different electric field combinations under the fixed reference voltage of the first contact to present different color patterns. By switching the voltage of a single contact (the second contact), the functions of the positive / negative / common electrodes in the traditional solution are equivalently realized.

[0009] Furthermore, the driving electrode layer is an electric field generating layer, which is used to convert the voltage signal input by the contact into a spatial electric field distribution to control the movement of particles in the electronic paper layer.

[0010] Furthermore, the multi-level timing driving signal is a discrete level signal whose multi-level input is controlled by a timing sequence.

[0011] Furthermore, the multi-level is preferably four levels.

[0012] Electronic paper particles respond nonlinearly, and increasing the number of levels will significantly increase the cost of the driver IC. However, if the number of levels is too small, fewer color levels can be modulated. Through time modulation, four levels can achieve dozens of visual color levels, which is the optimal solution combining cost and performance.

[0013] A second aspect of the present invention provides a control method for a dual-contact multi-level driven electronic paper nail art, comprising the following steps: Step 1: inputting a reference level signal to the driving electrode layer through the first contact, and inputting a multi-level driving signal to the driving electrode layer through the second contact; Step 2: driving the electrode layer to generate a spatially distributed electric field on the electronic paper layer based on the voltage difference between the first and second contacts; Step 3: The charged particles in the electronic paper layer migrate in a directed manner under the action of the electric field, displaying the target color.

[0014] Furthermore, the absolute value range of the voltage difference between the first and second contacts is 0V~15V.

[0015] The absolute value range of the voltage difference is 0v~15v, which is the threshold for the response of electronic paper particles. Too low a voltage cannot drive the particles, while too high a voltage may break down the microcapsules of the electronic paper layer, affecting the final display effect.

[0016] The voltage difference control of the present invention covers unipolar and bipolar solutions and has strong adaptability.

[0017] Furthermore, the charged particles in the electronic paper layer lock their positions due to the bistable property after the signal is removed so as to permanently display the desired color. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to better understand the solutions of the embodiments of the present invention, some relevant terms and concepts that may be involved in the embodiments of the present invention are first introduced below.

[0029] (1) Bistability refers to the physical property of electronic paper that after the driving electric field is removed, the charged particles are locked in space due to the balance between dielectrophoretic force and van der Waals force, and the color display state can be maintained without continuous power supply.

[0030] In this embodiment, a dual-contact multi-level driven electronic paper nail art device includes: a transparent cover; An electronic paper layer is provided on the lower end surface of the transparent cover; A driving electrode layer is provided on the lower end surface of the electronic paper layer and is electrically connected to the electronic paper layer; Two metal contacts, a first contact electrically connected to a reference level end of the driving electrode layer, for inputting a constant reference level; The second contact is electrically connected to the signal input end of the driving electrode layer and is used for inputting a timing driving signal including multiple levels.

[0031] The first contact is constantly connected to a reference voltage to provide an electric field reference anchor point; the second contact input includes a multi-level timing drive signal to form a dynamic electric field through a voltage difference.

[0032] Furthermore, the electronic paper layer is a color display execution layer that displays different colors based on the movement of charged particles.

[0033] Electronic paper contains charged color particles, whose movement is controlled by the direction and strength of the electric field between two electrodes. The direction of the electric field determines the direction of particle movement (floating / sinking), and the electric field strength determines the distance the particles move (the depth of color). The present invention adjusts the second contact voltage to form different electric field combinations under the fixed reference voltage of the first contact to present different color patterns. By switching the voltage of a single contact (the second contact), the functions of the positive / negative / common electrodes in the traditional solution are equivalently realized.

[0034] When the electronic paper layer receives the electric field given by the driving electrode, the pigment particles in the electronic paper capsule switch colors and patterns under the principle of electrophoresis.

[0035] Furthermore, the driving electrode layer is an electric field generating layer, which is used to convert the voltage signal input by the contact into a spatial electric field distribution to control the movement of particles in the electronic paper layer.

[0036] Furthermore, the multi-level timing driving signal is a discrete level signal whose multi-level input is controlled by a timing sequence.

[0037] The timing sequence controls the discrete level signals of the multi-level input, that is, the first voltage lasts for t1 time, the reference voltage lasts for t2 time, the second voltage lasts for t3 time, and the third voltage lasts for t4 time, with the input voltage and duration as the sequence input.

[0038] Furthermore, the multi-level is preferably four levels.

[0039] Electronic paper particles respond nonlinearly, and increasing the number of levels will significantly increase the cost of the driver IC. However, if the number of levels is too small, fewer color levels can be modulated. Through time modulation, four levels can achieve dozens of visual color levels, which is the optimal solution combining cost and performance.

[0040] like Figure 1 As shown, the second aspect of the present invention provides a control method for electronic paper nail art with dual-contact multi-level drive, comprising the following steps: Step 1: inputting a reference level signal to the driving electrode layer through the first contact, and inputting a multi-level driving signal to the driving electrode layer through the second contact; Step 2: driving the electrode layer to generate a spatially distributed electric field on the electronic paper layer based on the voltage difference between the first and second contacts; Step 3: The charged particles in the electronic paper layer migrate in a directed manner under the action of the electric field, displaying the target color.

[0041] Furthermore, the absolute value range of the voltage difference between the first and second contacts is 0V~15V.

[0042] The absolute value range of the voltage difference is 0v~15v, which is the threshold for the response of electronic paper particles. Too low a voltage cannot drive the particles, while too high a voltage may break down the microcapsules of the electronic paper layer, affecting the final display effect. 0v~15v can both meet the electronic paper driving needs and avoid causing the microcapsules of the electronic paper layer to break down.

[0043] The voltage difference control of the present invention covers unipolar and bipolar solutions and has strong adaptability. Unipolar means that multiple voltages are either positive or negative, while bipolar means that both positive and negative are available.

[0044] Furthermore, the charged particles in the electronic paper layer lock their positions due to the bistable property after the signal is removed so as to permanently display the desired color.

[0045] The bistability characteristic refers to the physical property of electronic paper that after the driving electric field is removed, the charged particles are locked in spatial position due to the balance between the dielectrophoretic force and the van der Waals force, and the color display state can be maintained without continuous power supply. This allows the color pattern required for the electronic nail art to remain unchanged for several days after being controlled, without the need for frequent control.

[0046] In this embodiment, a four-level control is adopted, the control scheme is a bipolar scheme, the reference level is 0v, the first voltage is 15v, the second voltage is -15v, and the third voltage is -7v. The input level signal waveform of the second contact is as shown in FIG. Figure 2 shown.

[0047] In another preferred embodiment of the present invention, if two different colors need to be displayed on the nail art, the electronic paper layer needs to be divided into two parts, and a third contact is added. The first electronic paper layer and the second electronic paper layer share the first contact that provides the reference level. The color of the first electronic paper layer is controlled by the multi-level drive signal of the second contact, and the color of the second electronic paper layer is controlled by the multi-level drive signal of the third contact.

[0048] The solution of the present invention can also be extended to display more blocks. For each additional display area, a control contact needs to be added, and the reference contact can be shared.

[0049] It should be noted that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments are merely examples, and any embodiments having substantially the same structure and effect as the technical concept within the scope of the technical solution of the present invention are all included in the technical scope of the present invention. In addition, without departing from the scope of the present invention, other embodiments that can be conceived by those skilled in the art and that combine some of the constituent elements in the embodiments are also included in the scope of the present invention.
