The specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.
Example one
In a first embodiment of the present invention, as shown in fig. 1 and 2, a brightness enhancement film includes: the light enhancement film comprises a light enhancement film body 1 and two light enhancement lugs 2 symmetrically arranged at the bottom of the light enhancement film body 1, wherein the light enhancement lugs 2 are arranged in an arc shape.
Specifically, the brightness enhancement film body 1 is of a square structure, and the brightness enhancement film body 1 generally has two pieces, namely an upper brightness enhancement film and a lower brightness enhancement film, the brightness enhancement film body 1 is used for enhancing the brightness generated by the backlight source, wherein one brightness enhancement film body 1 can increase the brightness by 60%, and if the two brightness enhancement film bodies 1 are orthogonal, the brightness can be increased by 100%, so that in the embodiment, the two brightness enhancement film bodies 1 are overlapped to increase the brightness by 100%;
it is worth explaining, add lustre to ear 2 and fix add lustre to the below of membrane body 1, and the size at adding lustre to ear 2 is according to concrete installation space and decides, and add lustre to ear 2 specifically for fan-shaped structure, its arc limit sets up in the order of keeping away from adding lustre to membrane body 1 to guarantee that the edge of adding lustre to ear 2 is enough slick and sly, does not have any edges and corners, makes the backlight light-emitting more even, has also further solved bad effects such as dark shadow and bright ray of corner simultaneously, the corner of here indicates add lustre to membrane body long limit with the hookup location department of membrane body minor face.
In this embodiment, a concave portion 3 is disposed at the middle position of the top of the brightness enhancement film body 1;
specifically, the recessed portion 3 is of a drop-shaped structure, and the recessed portion 3 is provided for meeting the use requirement of the drop screen on the market, and further, the recessed portion 3 in the embodiment can be changed according to the change of the opening position of the camera of the electronic product in the existing market, and is not limited to the position.
In this embodiment, the brightness enhancement film body 1 has two long sides and two short sides, and the long sides of the brightness enhancement film body and the short sides of the brightness enhancement film body which are adjacent to each other are connected through an arc surface;
specifically, the electronic product among the prior art is the rectangle structure mostly, therefore will add lustre to membrane body 1's laminating electronic product's shape to guarantee that the shape of membrane body 1 and display screen is unanimous, to guarantee that the demonstration of display screen is more even, the inhomogeneous condition of luminance is difficult for appearing, and add lustre to membrane body long limit with through the cambered surface connection between the membrane body minor face of adding lustre to, avoid adding lustre to membrane body 1 to have the edges and corners all around, further guaranteed the homogeneity of light-emitting.
In this embodiment, the light enhancement lug 2 is connected between the short edge of the light enhancement film and the cambered surface, and the light enhancement lug 2 and the light enhancement film body 1 are integrally arranged;
it is specific, add lustre to ear 2's mounted position can further improve the problem of light-emitting homogeneity, and more component is generally installed to the upper portion of current electronic product, the difficult mounted position who reserves to add lustre to ear 2, and electronic product's lower part can fully leave the space that can supply to add lustre to ear 2 installation, therefore in this embodiment, install the position department at the lower part of adding lustre to ear 2 with adding lustre to ear 2, add lustre to ear 2 and 1 integrative settings of membrane body simultaneously, the step of producing alone and processing to add lustre to ear 2 has been saved on the one hand, on the other hand can increase lustre to ear 2 and the joint strength of membrane body 1 that adds lustre to.
In the embodiment, the radian range of the light enhancement lug 1 is 2 pi/3-4 pi/3;
specifically, namely, the central angle of the brightening ear 1 is between 120 degrees and 240 degrees, due to the structural arrangement of the brightening film body 1, once the central angle is less than 120 degrees, the arc shape of the brightening ear 1 is not obvious and is close to the arc surface, so that the uniformity of light emission is influenced, and once the central angle is more than 240 degrees, the arc structure of the brightening ear 1 is changed into a shape close to the edge angle, so that the uniformity of light emission is influenced, and meanwhile, the conditions of dark shadow and bright rays can also occur;
it should be noted that, in the present embodiment, the radian of the brightening ear 1 is pi.
In the embodiment, the length and width of the brightening ear 1 are between 1.5mm and 3.5 mm;
specifically, the size of 1.5mm-3.5mm can be determined according to the specific size of the electronic product and the installation position of the reserved brightening ear 1.
To sum up, the embodiment of the utility model provides a membrane that adds lustre to through the setting of the ear 2 that adds lustre to of circular arc type, the edge of the ear 2 that adds lustre to that makes does not have the edges and corners more slick and sly for the light that the backlight sent is more even at the corner light-emitting of membrane body 1 that adds lustre to, can effectively improve bad effects such as corner shadow and bright ray.
