Description

Display screen protective glass

Technical Field

The utility model relates to a display screen protection lens belongs to and shows technical field.

Background

Display screens such as LCD, OLED, micro LED can be attached with certain protective lens in front, and the protective lens can not only protect the display screen, but also increase the aesthetic property of the display screen.

The display screen protective lens is generally provided with a shielding layer, and a space is reserved in the middle of the shielding layer to form a transparent window which is sleeved with a display area of the display screen.

In the case of an off screen, the display area of the display screen tends to be black, and thus the shielding layer is also generally designed to be black so as to coincide with the display area.

However, in practice, a large number of electrodes or film layers are arranged inside the display screen, and the electrodes or film layers often reflect light in the screen-off state, and the reflected light (intensity and color) changes greatly with the viewing angle, so that the color of the shielding layer is difficult to be consistent with that of the display screen. Some attempts to solve this problem by adjusting the color of the shielding layer have difficulty achieving the desired effect.

Therefore, when the current display screen protective lens is applied to a display screen, the shielding layer of the current display screen protective lens is often difficult to achieve the color and luster consistent with the color and luster of a display area, and the attractiveness of the current display screen protective lens is not ideal.

Disclosure of Invention

The utility model aims at providing a be used for display screen protection lens, it can improve shielding layer and display area's color and luster uniformity when using, has more ideal aesthetic property. The adopted technical scheme is as follows:

a protective lens for a display screen, characterized by:

comprises a transparent plate, a shielding layer and a light eliminating layer;

the shielding layer is arranged on the inner side surface of the transparent plate, and at least part of the shielding layer is left empty to form a transparent window;

the extinction layer is arranged on the inner side face of the transparent plate, is a soft layer with the light transmittance of not more than 40%, covers the transparent window and extends to the part of the shielding layer.

Specifically, the transparent plate may be a transparent glass plate or a plastic plate, particularly a transparent glass plate or a plastic plate having a thickness of 0.2mm to 2.0 mm. The shielding layer can be a single-layer or multi-layer black or dark ink layer, a photosensitive resin coating or a sticking film.

Therefore, when the protective lens is attached to the front of a display screen and the transparent window is aligned with the display area of the display screen, ambient light is reflected from the display area of the display screen in the screen-off state of the display screen to pass through the extinction layer twice in front and at the back, and the overall transmittance of the extinction layer is not more than 16% (namely 40% multiplied by 40%). In particular, in the case where the light transmittance of the matte layer is preferably not more than 20%, the total transmittance of ambient light reflected from the inside of the display region on the matte layer is not more than 4%. Therefore, the extinction layer greatly reduces the reflected light of the interior of the display area to the outside light, even if the reflected light changes along with the viewing angle, the reflected light can be directly ignored, and the shielding layer is designed to be black enough, so that the shielding layer can be consistent with the color of the display area, and the display area has ideal aesthetic property when being applied.

The extinction layer is a soft layer, and specifically, it may be a soft material layer having elasticity or plasticity. The thickness is preferably 10 μm to 200. mu.m. Preferably, the extinction layer comprises a soft glue layer and light absorbers distributed in the soft glue layer, and in order to realize the light transmittance of the extinction layer which is not more than 40%, the proportion of the light absorbers in the soft glue layer is only required to be adjusted. The soft adhesive layer may be further preferably an acrylic resin layer or a silicone layer. The light absorber may further preferably be a carbon particle or a dye molecule. Because the extinction layer is a soft layer, the extinction layer can overcome the height difference between the shielding layer and the transparent window through deformation (the shielding layer generally has a single-layer height of 5-200 μm) to fill the edge inner angle of the shielding layer, so that bubbles are prevented from being left in the edge inner angle of the shielding layer, and when the protective lens is applied, the display area and the shielding layer can be in continuous transition in color and luster.

In order to further ensure that the extinction layer can fill the inner corner of the edge of the shielding layer, the protective lens preferably further comprises a flattening layer, wherein the flattening layer is adhered to the inner side of the extinction layer, covers the transparent window and extends to part of the shielding layer. Specifically, the flattening layer is a transparent plastic film (such as a PET film) or a transparent glass plate with the thickness of 20-300 μm, and the flattening layer is arranged and can be pressed during application, so that the extinction layer clamped in the flattening layer is pressed to fill the inner corners of the edges of the shielding layer.

Preferably, the protective lens further comprises a touch circuit, and the touch circuit and the display screen can form a touch display when the protective lens is applied. Specifically, the touch circuit may be disposed on an inner side surface of the transparent plate or an inner side surface of the shielding layer. In addition, the flattening layer can also be provided with a touch circuit layer, especially in the case that the flattening layer is a transparent glass plate.

Compared with the prior art, the utility model provides a display screen protection lens has following beneficial effect:

when the protective lens is attached to the front of a display screen and the transparent window is aligned with the display area of the display screen, ambient light is reflected from the display area of the display screen in a screen-off state, the ambient light needs to pass through the extinction layer twice in front and at the back, and the overall transmittance of the extinction layer is not more than 16% (namely 40% multiplied by 40%). Therefore, the extinction layer greatly reduces the reflected light of the interior of the display area to the outside light, even if the reflected light changes along with the viewing angle, the reflected light can be directly ignored, and the shielding layer is designed to be black enough, so that the shielding layer can be consistent with the color of the display area, and the display area has ideal aesthetic property when being applied. In addition, because the extinction layer is a soft layer, the extinction layer can overcome the height difference between the shielding layer and the transparent window through deformation to fill the inner corners of the edges of the shielding layer, so that bubbles are prevented from being left in the inner corners of the edges of the shielding layer, and the display area and the shielding layer can be in continuous transition in color and luster when the protective lens is applied.

The following further describes the design of the present invention with reference to the drawings and examples.

Detailed Description

Example one

As shown in fig. 1, 2 and 3, the display screen protective lens 100 includes a transparent plate 10, a shielding layer 20 and a matting layer 30.

The transparent plate 10 is a transparent glass plate (or a transparent plastic plate) with a thickness of 0.55mm (0.2 mm-2.0 mm), and is cut and engraved to form the required lens contour dimension.

The shielding layer 20 is a black cured photosensitive resin layer (which may be an ink layer or a light-shielding film) having a thickness of 20 μm (any of 5 μm to 200 μm) provided on the inner surface of the transparent plate 10, and a transparent window 21 for protecting the lens 100 is formed in the middle of the transparent plate 10.

The extinction layer 30 is arranged on the inner side of the transparent plate 10, covering the transparent window 21 and extending over and covering the edges of the shielding layer 20. The matte layer 30 is mainly made of a soft acrylic resin mixed with carbon particles (or dye molecules) as a light absorber, and has a thickness of 40 μm. By setting the ratio of the absorbants, the extinction layer 30 has only about 20% transmittance. At the edges of the masking layer 20, the matting layer 30 is deformed to fill the interior corners 22 of the edges of the masking layer 20 to avoid leaving air bubbles in the interior corners 22 of the edges of the masking layer 20.

As shown in fig. 3, when the protection lens 100 is attached to the front of a display screen 200, and the transparent window 21 is aligned on the display area of the display screen 200, when the display screen 200 is in a screen-off state, ambient light is reflected from the display area to pass through the extinction layer 30 twice, and the total transmittance of the display screen on the extinction layer 30 is not greater than 4%, so that the reflection of the display area to the external light is greatly reduced, and even if the reflected light changes with the viewing angle, the reflected light can be ignored directly. Since the shielding layer 20 is black, it has the same color as the display area, and it has a desirable aesthetic property when applied. The soft light-extinction layer 30 fills the inner corners 22 at the edges of the shielding layer 20, and no air bubbles remain to enable the continuous transition in color between the display area and the shielding layer 20. Therefore, the protective lens 100 has a desirable aesthetic property when applied.

In other embodiments of the present embodiment, the protection lens 100 may further include a touch circuit, so that it and the display screen 200 may form a touch display.

According to the actual design requirement, in other embodiments of the present embodiment, the light transmittance can be made to be other values not greater than 40% by changing the thickness of the extinction layer 30 or the ratio of the light absorbers.

Example two

As shown in fig. 4, in addition to the first embodiment, a 30 μm thick (any of 20 μm to 300 μm) PET film as a flattening layer 40 is added to the inner side of the transparent plate 10, thereby constituting the second embodiment of the present invention. The flattening layer 40 is adhered to the inner side of the transparent plate 10 by the soft extinction layer 30, and the soft extinction layer 30 can be flattened by the flattening layer 40 in the manufacturing process or the process of assembling the display screens 200, so that the extinction layer 30 can be further ensured to fill the inner corners 22 of the edges of the shielding layer 20.

EXAMPLE III

As shown in fig. 5, in addition to the first embodiment, a transparent second glass plate is added as a flattening layer 40' on the inner side of the transparent plate 10, thereby forming a second embodiment of the present invention. The second glass plate 40' is adhered to the inner side of the transparent plate 10 by the soft extinction layer 30, and the soft extinction layer 30 can be flattened by the flattening layer 40 in both the manufacturing process and the process of assembling the display screens 200, so that the extinction layer 30 can be further ensured to fill the inner corners 22 of the edges of the shielding layer 20.

The second glass plate can be provided with a second touch circuit (the glass plate can also be provided with a touch circuit at the same time), so that the second glass plate and the display screen 200 can form a touch display.

In addition, it should be noted that the names of the parts and the like of the embodiments described in the present specification may be different, and all the equivalent or simple changes made according to the structure, the features and the principle of the present invention are included in the protection scope of the present invention.
