Embodiment Construction

[0032] The invention will be described in further detail below in conjunction with specific embodiments.

[0033] Such as figure 1 The homogenizing film 11 shown includes a substrate 2, and a plurality of dimple lenses 3 are closely arranged on the first end surface 21 of the substrate 2 (see figure 2 ), these micro-concave lenses 3 cover the first end surface 21 of the uniform film 11, and two adjacent micro-concave lenses 3 are partially stacked, so that the duty cycle of the first end surface 21 reaches 100%. The size of each dimple lens 3 is not the same, specifically see image 3 and Figure 4 : the depression depths D of each micro-concave lens 3 are not all equal, but all take values ​​in the range of 0.1 μm-5 μm; the concave bottoms B of each micro-concave lens 3 are not all flush with each other; the notches T of each micro-concave lens 3 are not all flush with each other . The notches T of some microconcave lenses 3 are not parallel to the first end surface 21 ,...

Abstract

The invention relates to the field of optical film materials, in particular to a dodging film and a backlight packaging module. The invention provides a dodging film which comprises a substrate, a plurality of micro-concave lenses are closely arranged on the first end face of the substrate, and every two adjacent micro-concave lenses are partially stacked. The mutual relation of the micro-concave lenses meets the condition that the concave bottoms of the micro-concave lenses are not completely flush with one another and / or the concave openings of the micro-concave lenses are not completely flush with one another and / or the concave depths of the micro-concave lenses are not completely equal. According to the light uniformizing film, the duty ratio of the micro lens surface is high, the haze is high, the light transmitting effect is not affected, and the light uniformizing effect of the light uniformizing film is good. The invention further provides a backlight source packaging module adopting the light uniformizing film, and the light uniformizing effect of the backlight source packaging module is good.

Description

technical field [0001] The invention relates to the field of optical film materials, in particular to a uniform light film and a backlight source packaging module. Background technique [0002] The LCD display module has a wide range of application scenarios. An existing LCD display module includes a display screen and a backlight module. The backlight module is equipped with a backlight board, on which there are multiple Mini LED light sources, and the light emitted by each Mini LED light source is regarded as a point light source, and the light intensity of the point light source is concentrated in the center. If multiple Mini LED light sources are directly projected on the display screen, it will cause uneven light and dark images on the display screen, which will affect the visual effect of the imaging screen. A plurality of dodging films are installed to dodge the light of the point light source. There is an existing light uniform film, the main body of which is a sub...
