[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6An upper structure of a color electronic ink display screen includes a protective layer 1, a touch-sensing layer 2, a color filter layer 3, and an electronic ink layer 4, as well as a edging frame composed of a bottom frame 5 and a top frame 6. The protective layer 1 is located at the top of the edging frame, the touch-sensing layer 2 is located at the bottom of the protective layer 1, the color filter layer 3 is located at the bottom of the touch-sensing layer 2, and the electronic ink layer 4 is located at the bottom of the color filter layer 3. The electronic ink layer 4 is attached to the bottom of the edging frame. The protective layer 1, the touch-sensing layer 2, the color filter layer 3, and the electronic ink layer 4 are connected sequentially by applying optically transparent adhesive. The optically transparent adhesive has high transparency and good adhesion properties, which can ensure seamless bonding between the layers, reduce light reflection and refraction between layers, and improve the light transmittance and display effect of the screen.

[0027] Furthermore, the edge-binding frame consists of a bottom frame 5 and a top frame 6, with the bottom frame 5 at the bottom and the top frame 6 at the top. The four corners of the bottom frame 5 and the top frame 6 are connected by matching screws. The bottom frame 5 has a support block 8 inside, and the top frame 6 has a rubber clamping block 7 inside. The rubber clamping block 7 and the support block 8 form a fixing groove. The fixing groove inside the edge-binding frame can effectively protect the protective layer 1, the touch sensing layer 2, the color filter layer 3, and the electronic ink layer 4, preventing internal cracks caused by edge collisions and improving the overall screen protection effect.

[0028] Furthermore, the protective layer 1 is composed of an optical processing layer 9 and a base material layer 10. The base material layer 10 is located at the bottom of the protective layer 1, and the bottom end of the base material layer 10 is attached to the touch sensing layer 2. The optical processing layer 9 is located at the top end of the base material layer 10. The base material layer 10 is either high-strength glass or transparent plastic. The high-strength glass, i.e., tempered glass, is processed through a special heat treatment process to form a compressive stress layer on the glass surface and a tensile stress layer inside, which greatly improves its impact and scratch resistance. It can effectively resist the scratches of sharp objects and the collisions in daily use, providing reliable physical protection for the display screen. The transparent plastic, polycarbonate, is a thermoplastic engineering plastic with excellent comprehensive performance. It has good optical properties, high light transmittance, and excellent toughness and impact resistance. It is not easy to break and can protect the internal components from damage while ensuring the visibility of the display screen.

[0029] Furthermore, the bottom of the optical processing layer 9 is an anti-glare coating 12, which is connected to the base material layer 10. The top of the optical processing layer 9 is an oleophobic and hydrophobic coating 11. The microstructure of the anti-glare coating 12 has a special texture that can scatter and diffuse ambient light, preventing strong specular reflection on the screen surface and reducing screen reflection from interfering with the user's vision. The oleophobic and hydrophobic coating 11 can reduce the surface energy of the screen surface, making it difficult for liquids such as water and oil to adhere and spread. This makes it easier for users to wipe the screen, keep it clean, reduce the impact of stains on the display effect, and extend the screen's lifespan.

[0030] Furthermore, the color filter layer 3 is composed of two parts: a substrate 13 and multiple filter units 14. The bottom end of the color filter layer 3 is the substrate 13, which is connected to the electronic ink layer 4. The top end of the substrate 13 is provided with a layer of filter units 14 arranged at equal intervals.

[0031] Furthermore, the filter unit 14 contains three primary color blocks 16, and the three primary color blocks 16 are combined into an equilateral triangle pixel group by red, green and blue filter units. An optical isolation ring 15 is provided on the outside of the filter unit 14. The triangular arrangement of the three primary color blocks 16, through reasonable layout, can improve the brightness and contrast of the screen while ensuring color accuracy. The optical isolation ring 15 is an optical isolation material with low refractive index. This material can change the propagation path of light. When light propagates to the edge of the filter unit, it will be guided by this isolation material to avoid entering the adjacent filter unit, thereby achieving an effect similar to the black matrix blocking light crosstalk.
