[0029] The scheme of the embodiments of the present application will be described in detail below with reference to the accompanying drawings of the specification. In the following description, specific details such as specific system structures, interfaces, techniques, etc. are presented in order to thoroughly understand the present application, but are not intended to limit the present application.

[0030] The present application provides an electronic display, please refer to Figure 1 , Figure 1 is a structural exploded view of a first embodiment of the electronic display of the present application.

[0031] The electronic display 100 includes:

[0032] The display layer 101 is provided with a plurality of pixel units (not shown in the figure) arranged in an array, for displaying a pixel pattern; the cover plate 102 covers the display layer 101.

[0033] The display layer 101 can be a display layer 101 formed of liquid crystal, light-emitting diode, electronic ink or other display technology composite material. By applying a certain voltage to the display layer 101, the brightness and color of each pixel unit displayed are controlled. Changes in applied voltage result in changes in state, thereby displaying different colors or gray scales, which are combined to form a certain pixel pattern.

[0034] The cover plate 102 protects the display layer 101 of the display 100 from direct contact with dust, oil stains and fingerprints, improves the durability of the display 100, and provides better display effect for the display layer 101.

[0035] The electronic ink layer 103 includes electronic ink particles (not shown in the figure) and is disposed between the display layer 101 and the cover plate 102; the electronic ink layer 103 is used to display colors based on the pixel pattern.

[0036] The microcapsules in the electronic ink layer 103, as display units, contain charged pigment electronic ink particles suspended in a clear liquid. Two, three or more kinds of colored electronic ink particles can be encapsulated in the microcapsules, usually white pigment particles with positive charges and colored pigment particles with negative charges. When an electric field of a certain direction is applied, the corresponding pigment particles are moved to the side of the microcapsules close to or away from the cover plate 102, thereby displaying different colors.

[0037] Please refer to Figure 2 , Figure 2 is a structural top view of the first embodiment of the electronic display of the present application.

[0038] The electronic display 100 generates a corresponding voltage signal to control the position of the movement of the electronic ink particles (not shown in the figure) according to the voltage signal of the display layer 101, thereby controlling the color and gray scale displayed by each microcapsule and displaying the corresponding color. For example, according to the background color of the pixel pattern displayed by the display layer 101, the electronic ink layer 103 displays the same or similar color, or displays a preset color to form a personalized design of the frame color, wherein the color that can be displayed by the electronic ink layer 103 can be a gradient or a uniform one or more color blocks.

[0039] Please refer to Figure 3 , Figure 3 is an exploded view of the second embodiment of the electronic display of the present application.

[0040] In an alternative embodiment, the electronic ink layer 103 has a hollow frame structure, and at least part of the display layer 101 is exposed through the hollow part.

[0041] The circuit or electronic elements required to accommodate the layers of the display 100, especially the circuit for signal interaction between the layers, will be arranged in the frame area to avoid affecting the display effect of the display layer 101. The hollow frame structure of the electronic ink layer 103 can effectively shield the circuit and form a relatively continuous picture with the pixel pattern displayed by the display layer 101, thereby achieving better visual display effect.

[0042] Please refer to Figure 4 , Figure 4 is a structural top view of an embodiment of the electronic ink layer of the second embodiment of the electronic display of the present application. In an alternative embodiment, the frame structure is a one-piece structure or includes multiple sub-ink layer plates 1031, which are enclosed by the multiple sub-ink layer plates 1031. In a specific embodiment, the one-piece structure can improve the integration between materials and can have better continuous color display effect.

[0043] Please refer to Figure 5 , Figure 5is a top view of another embodiment structure of the electronic ink layer of the second embodiment of the electronic display of the present application. In another specific embodiment, by seamlessly splicing the sub-ink layer plate 1031, the budget can be effectively reduced, while avoiding the need for overall replacement due to damage, and having good maintainability. The frame structure of the electronic ink layer 103 of the product can be set according to the size of the display 100, and the production mode of the sub-ink layer plate 1031 process.

[0044] In an optional embodiment, a functional layer 104 is provided between the display layer 101 and the electronic ink, and the functional layer 104 includes a touch layer 1041 and / or a light source layer 1042; and the electronic ink layer 103 covers the functional layer 104.

[0045] The devices and circuits of the functional layer 104 are arranged around the frame of the display 100, exposing the display layer 101 and avoiding affecting the display effect of the display layer 101. The touch layer 1041 provides an interactive mode for the display 100, which can be directly interacted through touch. The light source layer 1042 provides a light source with adjustable uniform brightness for the display 100, such as providing front light for the display layer 101, or providing backlight for the electronic ink layer 103, etc., so that the display layer 101 can improve the contrast and brightness of the display 100 in various application scenarios, and enhance the display effect. In other embodiments, the functional layer 104 can also include a polarizing or filtering layer to improve the display effect, or a magnetic induction layer 1052, an infrared induction, light induction, or a camera to improve the interactive effect.

[0046] Please refer to Figure 6 , Figure 6 is a structure cross-sectional view of the second embodiment of the electronic display of the present application.

[0047] In an optional embodiment, a transparent adhesive layer 1021 for fixing is provided between the cover plate 102 and the electronic ink layer 103, between the display layer 101 and the electronic ink layer 103, and between the cover plate 102 and the display layer 101.

[0048] In a specific embodiment, the transparent adhesive layer 1021 fixes the cover plate 102 and the display layer 101 through the hollow part of the electronic ink layer 103.

[0049] In order to ensure the display effect of the pixel pattern of the display layer 101 displayed through the cover plate 102, the transparent adhesive is filled between the cover plate 102 and the display layer 101, which can avoid the change of materials such as air affecting the light propagation to cause the deformation of the pixel pattern, and can also improve the firmness of the display 100.

[0050] In a specific embodiment, the transparent adhesive layer 1021 is a multi-layer coating that is pressed together to form a whole transparent adhesive layer 1021. Preferably, the transparent adhesive layer 1021 is completely adhered together in a seamless manner to provide better display effect and prevent dust and moisture from entering between the layers of materials, thereby effectively ensuring the optical transmittance of the display layer 101 and the electronic ink layer 103 and ensuring the display effect of the display 100. In other embodiments, the transparent adhesive layer 1021 can also be partially glued to form a discontinuous transparent adhesive layer 1021 for fixation.

[0051] It can be understood that the layers of the functional layer 104 of the display 100, the functional layer 104 and the electronic ink layer 103, and the functional layer 104 and the display layer 101 can be fixed by the transparent adhesive layer 1021. In other embodiments, ordinary adhesive can also be used for fixation.

The electronic ink layer 103 is loaded with a first polarity voltage, and the electronic ink particles are in a first position state. The electronic ink layer 103 is loaded with a second polarity voltage, and the electronic ink particles are in a second position state. Wherein, the electronic ink particles are in different position states, and the electronic display 100 displays different colors.

[0054] In a specific embodiment, the microcapsules in the electronic ink layer 103 act as display units and contain charged pigment electronic ink particles suspended in a clear liquid. The microcapsules can encapsulate black and white colored electronic ink particles, which are usually positively charged white pigment particles and negatively charged colored pigment particles.

[0055] According to the principle of positive and negative attraction, when the electronic ink layer 103 is loaded with a first polarity voltage, such as a maximum working number of negative polarity voltage on the side close to the cover plate 102, the white electronic ink particles are close to the cover plate 102, and the black electronic particles are away from the cover plate 102, displaying white. When the electronic ink layer 103 is loaded with a second polarity voltage, such as a maximum working number of positive polarity voltage on the side close to the cover plate 102, the black electronic ink particles are close to the cover plate 102, and the white electronic particles are away from the cover plate 102, displaying black. Other polarity voltages of other voltages can also be applied to mix the two colors of electronic ink particles to present different shades or brightness of gray, so that the entire electronic ink layer 103 presents different color effects.

[0056] Please refer to Figure 8 , Figure 8is a structural sectional view of the display layer of the third embodiment of the electronic display of the present application.

[0057] In a specific embodiment, the display layer 101 comprises a first electronic ink film 1011 and a device layer 1012 arranged in a stack, the first electronic ink film 1011 is arranged on one side of the electronic ink layer 103, and the device layer 1012 is arranged on the side of the first electronic ink film 1011 away from the electronic ink layer 103, the device layer 1012 comprises a driving transistor (not shown in the figure), and the driving transistor is used to receive a driving signal to display a pixel pattern.

[0058] The first electronic ink film 1011 comprises electronic ink particles (not shown in the figure), and a pixel unit is formed by different color electronic ink particles, each driving transistor is connected to each pixel unit, and the size of the current flowing between the source and the drain of the transistor is adjusted by sending a driving signal to the gate to control the arrangement of the electronic ink particles, thereby changing the gray scale or color of the pixel unit.

[0061] In order to ensure the display effect and color uniformity of the electronic ink layer 103 and the display layer 101, the electronic ink particles (not shown in the figure) of the first electronic ink film 1011 and the second electronic ink film 1032 can be two kinds of electronic ink particles of black and white of the same color, and in other embodiments, they can be white or other color electronic ink particles.
