Description

Light leakage prevention electronic ink screen

Technical Field

The application belongs to the technical field of electronic ink screens, and particularly relates to an electronic ink screen capable of preventing light leakage.

Background

Electronic ink screens (commonly referred to as electronic paper) have a display effect similar to that of ink paper due to their reflective (non-self-luminous) bistable display technology. Compared with the common LCD, OLED and other self-luminous and back-luminous liquid crystal screens, the ink screen has no flicker or blue light, and the damage and fatigue feeling to eyes caused by watching the ink screen for a long time are far less than the influence of watching a mobile phone and a flat screen under the same condition. Aiming at the characteristic of the ink screen, manufacturers develop ink screen electronic books and electronic paper products, are pursued by a plurality of reading enthusiasts, and become helpful aids for people in the aspects of reading, education, scientific research and the like.

With the promotion of the market and the improvement of the user demand, the user has a higher pursuit for the screen appearance and the display effect of the electronic book product. In addition to higher definition and larger screen sizes, users also demand ink screen products that are flat, less prone to dust, shatter, non-reflective, and more importantly, light-tight. The characteristics of the former points can be achieved by covering the ink screen with an etched glass cover plate. However, the problem of light leakage has been solved only by absorbing light by filling a dark color paint in the light leakage region of the frame under the glass cover plate. The disadvantage of this is that the product can only be made with a dark border appearance, and therefore the requirements of some users who want a light-colored cover plate border appearance cannot be met.

The light leakage problem is mainly caused by that the reading lamp light emitted by the front light guide plate is diffracted and refracted when passing through the glass cover plate, and a halo is generated at the peripheral frame of the cover plate. When the thickness value of the glass cover plate is larger, the light leakage area is larger, and the light leakage is more obvious.

In order to meet the requirements of light-colored product frames and light leakage prevention in the prior art, etched glass materials are abandoned, PMMA composite material cover plates are selected instead, and because PMMA can be made into multi-layer polymerization, the upper layer is coated with light-colored paint as the appearance color of the frames, and the lower layer is coated with dark paint to prevent light leakage. Wherein the AG film positioned at the uppermost portion of the product can provide a specified haze, anti-glare. The upper layer of the multilayer coating below the AG film is light gray to set the appearance color of the frame, and the lower layer is black to absorb light to prevent light leakage. However, the above PMMA material has the following disadvantages compared with the etched glass cover plate: the PMMA material has lower surface strength and is easy to scratch; the PMMA screen has lower transmittance and definition, blurred vision, higher haze and roughness, and cannot fully exert the resolution effect; the cost is higher, and the process yield is lower; the problem of gap light leakage cannot be solved, and the heat dissipation effect is poor.
