Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical film, especially a novel bright film. BACKGROUND

[0002] Optical film plays a vital role in the field of liquid crystal display devices, such as liquid crystal televisions, liquid crystal displays, smart phones and tablet computers. With the continuous pursuit of lighter and thinner display effects in liquid crystal display technology, the brightness enhancement film is also evolving towards ultra-thin and composite.

[0003] Under this background, the combination of diffusion film and brightness enhancement film is particularly important. Diffusion film can effectively balance the distribution of light through its unique light uniformity, while brightness enhancement film further enhances the focusing effect of light through its light gathering property. However, the diffusion film in the traditional backlight module, although it performs well in correcting the light diffusion angle, inevitably leads to the expansion of the light radiation area, thereby sacrificing the light intensity per unit area, i.e. reducing the brightness.

[0004] At the same time, although the brightness enhancement film successfully focuses the scattered light in the normal viewing angle direction through the ingenious refraction and internal total reflection of the prism structure, it significantly improves the brightness of the LCD and the utilization rate of light energy, but the traditional prism structure often follows a fixed arrangement rule, resulting in that the light enhancement effect is limited to a specific direction, and the comprehensive performance of brightness enhancement and diffusion still needs to be improved. SUMMARY

[0008] The novel bright film of the utility model uses incompletely elliptical modules arranged symmetrically to form a light collecting layer and a light emitting layer, better focuses light beams, improves the brightness of light sources passing through the module, and significantly enhances the light enhancement effect.

[0009] In addition, the novel bright film according to the application can have the following additional technical features:

On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0019] The novel bright film of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0020] As Figure 1 shown, the novel bright film of the embodiments of the present application comprises a base layer 10, an adhesive layer 20, a light receiving layer 30 and a light emitting layer 40.

[0021] The two groups of adhesive layers 20 are respectively coated on the upper and lower surfaces of the base layer 10, the light collecting layer 30 is attached to the lower surface of the lower group of adhesive layers 20, and the light emitting layer 40 is attached to the upper surface of the upper group of adhesive layers 20.

[0022] It should be noted that the adhesive layer 20 is a glue layer made of acrylic resin, so the adhesive layer 20 has good adhesion, and the adhesive layer 20 has good refractive index and good light transmittance. The light collecting layer 30 collects the light beam, then condenses the light beam through the base layer 10, and finally emits the condensed light beam through the light emitting layer 40 to enhance the brightness.

[0023] In an embodiment of the present application, as shown in Figure 1 The base layer 10 is a nano core layer, and the thickness of the base layer 10 is 25-75 μm.

[0024] It should be noted that the base layer 10 uses a nano core layer to concentrate the light beam, focus the light, and transmit the light.

[0025] In an embodiment of the present application, as shown in Figure 1 The light collecting layer 30 and the light emitting layer 40 are respectively an incomplete elliptical coating, and the light collecting layer 30 and the light emitting layer 40 are symmetrically arranged.

[0026] It should be noted that the light collecting layer 30 and the light emitting layer 40 are in the form of an incomplete ellipse, and the light collecting layer 30 concentrates the light beam and diffuses the light beam through the light emitting layer 40 to enhance the brightness.

[0027] In an embodiment of the present application, as shown in Figure 1 The light collecting layer 30 and the light emitting layer 40 are PC films, the thickness of the light emitting layer 40 is 50-168 μm, and the light transmittance of the light emitting layer 40 is 75-90.

[0028] It should be noted that the light emitting layer 40 emits light, and the light emitting layer 40 is made of PC film, and then the light emitting layer 40 brightens the light beam.

[0029] Further, the specific shape of the light emitting layer 40 and the light collecting layer 30 is set according to actual needs and application scenarios.

[0030] In an embodiment of the present application, as shown in Figure 1 The adhesive layer 20 is acrylic resin, and the refractive index of the adhesive layer 20 is 1.45-1.6.

[0031] It should be noted that the refractive index of the adhesive layer 20 ensures good light transmittance, and then the light collecting layer 30 and the light emitting layer 40 are adhered and fixed through the adhesive layer 20, thereby generating a novel bright film.

[0032] Specifically, the light bright film uses the steps of: the light beam is irradiated from below the light receiving layer 30, the light beam is collected through the light receiving layer 30, then the light beam is gathered through the base layer 10, and finally the light beam is scattered out through the light emitting layer 40. Through the design of the incomplete ellipse of the light receiving layer 30 and the light emitting layer 40, the light beam is focused to increase the brightness, so that the light bright film effectively improves the brightness.

[0033] In summary, the novel light bright film of the embodiment of the present application adopts the incomplete elliptical modules arranged in a symmetrical manner to form the light receiving layer and the light emitting layer, better focuses the light beam, improves the brightness of the light source passing through the module, and the light enhancement effect is obvious.
