Embodiment 1

[0028] Such as figure 1 As shown, a light-leakage-proof electronic ink screen includes: a glass touch panel 10, a touch sensing layer 20, a light guide plate 30, and an ink display 40 arranged sequentially from the surface to the inside, the glass touch panel 10 and A first optical adhesive layer A is arranged between the touch sensing layers 20, and a first dark paint layer C is coated on the light leakage area M of the first optical adhesive layer A. On the glass touch panel 10, The side surfaces of the touch sensing layer 20 , the light guide plate 30 and the ink display screen 40 are further provided with a second dark paint layer D, and the second dark paint layer D is arranged from the surface to the inside.

[0029] In this embodiment, the light leakage area M of the first optical adhesive layer A is coated with the first dark paint layer C, so as to weaken the reflection and transmission of light to a large extent; in the glass touch panel 10 The sides of the touch se...

Embodiment 2

[0040] Such as figure 2 As shown, an electronic ink screen that prevents light leakage, this embodiment is also provided with an anti-glare AG film 50 on the basis of the first embodiment above.

[0041]Specifically: in this embodiment, the glass touch panel 10, the touch sensing layer 20, the light guide plate 30, and the ink display screen 40 are sequentially arranged from the outside to the inside, the glass touch panel 10 and the touch sensing layer 20 The first optical adhesive layer A is arranged between them, the light leakage area M of the first optical adhesive layer A is coated with the first dark paint layer C, and the glass touch panel 10, the touch sensing layer 20, the light guide plate 30 and the side of the ink display screen 40 are also provided with a second dark paint layer D, and the second dark paint layer D is arranged from the surface to the inside.

[0042] In this embodiment, a thin layer of AG film 50 is also configured, and the AG film 50 covers th...

Abstract

The invention discloses an electronic ink screen capable of preventing light leakage. The electronic ink screen comprises a glass touch panel, a touch sensing layer, a light guide plate and an ink display screen which are sequentially arranged from outside to inside, a first optical adhesive layer is arranged between the glass touch panel and the touch sensing layer, and a light leakage area of the first optical adhesive layer is coated with a first dark color coating layer; and second dark color coating layers are further arranged on the side surfaces of the glass touch panel, the touch sensing layer, the light guide plate and the ink display screen and arranged from outside to inside. The problem of light leakage of an electronic ink screen product is solved, the visual experience of a user on the screen is greatly improved, and meanwhile the protection effect on eyes is also enhanced.

Description

technical field [0001] The present application belongs to the technical field of electronic ink screens, and in particular relates to an electronic ink screen that prevents light leakage. Background technique [0002] Electronic ink screen (commonly known as electronic paper) because of its reflective (no self-illumination) bistable display technology, the screen display effect is like ink paper. Compared with ordinary LCD, OLED and other self-illuminating and back-emitting LCD screens, the ink screen has no flicker and no blue light, and the damage and fatigue caused by watching the ink screen for a long time are far less than watching mobile phones under the same conditions. and the impact of flat screens. In response to this feature of the ink screen, the manufacturer has developed ink screen e-books and electronic paper products, which are sought after by many reading enthusiasts and become people's effective assistants in reading, education, and scientific research. ...
