Description
Technical Field
The utility model relates to an ink screen electronic book technical field especially relates to a leak protection light ink screen electronic book touch-sensitive screen and electronic equipment.
Background
The electronic ink screen is based on electrophoresis technology to achieve the display effect. Principle of electronic ink screen: the electronic ink screen is composed of a plurality of electronic inks, and the electronic inks can be seen as capsules. Each capsule has liquid charges, wherein the positive charges are white, and the negative charges are black. When we apply positive and negative voltages to one side, the charged liquid will be attracted and repelled respectively. Thus, each pixel point can display white or black. After the picture is formed, all the particles can not move any more, and the picture can not disappear even if the power is cut off. Therefore, when you look at the same page, the screen will not flash. The electronic ink screen only consumes power when the operations such as page turning and the like are carried out, and if the display content is not refreshed, even if the power supply is turned off, the picture on the display screen can still be kept, so that the electronic ink screen has the advantage of power saving, but the reading effect of the electronic ink screen is very close to that of a paper book and cannot be seen clearly under weak light and no light. Therefore, in the existing design, a light guide plate with a plurality of LED beads on one side is usually added between the electronic ink screen and the touch module to enhance the display brightness. Touch module, light guide plate and electronic ink screen equipment are in the same place, and the phenomenon of edge light leak can appear in the light guide plate, influences user experience and feels.

The printing ink shielding layer 11 is used for shielding the edge light-tight area of the touch control function layer below the printing ink shielding layer and the frame light-tight area of the electronic ink screen, so that the touch screen is attractive in appearance.
The touch functional layer 20 includes a main body 21 and a flange 22 extending from the edge of the main body 21 to a direction away from the protective cover 10, the flange 22 and the main body 21 are integrally formed, the main body 21 and the flange 22 cooperate to form an accommodating space, and the light guide plate 40 is completely accommodated in the accommodating space.
Further, the main body 21 includes a display area 211 located in the middle and a non-display area 212 located in the edge, the non-display area 212 surrounds the display area 211, the non-display area 212 and the flange 22 are combined to form an invisible portion, and the invisible portion is covered by the opaque layer 30.
The touch functional layer 20 further includes a flexible circuit board, and the flexible circuit board is connected to the end of the flange 22.
The opaque layer 30 is used to cover the invisible part, the OD (optical density) value of the opaque layer 30 is greater than or equal to 5 (the OD value is used to measure the ability of the material to absorb light, the larger the value is, the stronger the ability to absorb light is, i.e. the lower the transmittance is), the opaque layer 30 has a bending characteristic, and the opaque layer 30 may be black flexible ink or other materials with the same characteristics.
The light-impermeable layer 30 is disposed on a side of the invisible part close to and/or far away from the light guide plate 40, that is, the light-impermeable layer 30 may be disposed only on a side of the invisible part close to the light guide plate 40; the invisible part may be provided only on a side away from the light guide plate 40; it is also possible to provide both sides of the invisible portion close to and away from the light guide plate 40.
