Embodiment 1

[0026] Such as figure 1 As shown, the black and white film includes a white structural layer 110 and a black structural layer 120 . The white structural layer 110 is co-extruded with the black structural layer 120 .

[0027] The white structural layer 110 is composed of engineering plastics with a mass ratio of 39% to 98.8%, a white dye with a mass ratio of 0.05% to 30%, an antioxidant with a mass ratio of 0.05% to 1%, and a mass ratio of 0.05-4 % anti-ultraviolet absorber, 0.05% to 20% flame retardant by mass ratio, 1% to 6% antistatic agent by mass ratio, and a small amount of dispersant, compatibilizer and lubricating aid.

[0028] The black structural layer 120 is composed of engineering plastics with a mass ratio of 39% to 98.8%, a black dye with a mass ratio of 0.05% to 30%, an antioxidant with a mass ratio of 0.05% to 1%, and a mass ratio of 0.05-4 % anti-ultraviolet absorber, 0.05% to 20% flame retardant by mass ratio, 1% to 6% antistatic agent by mass ratio, and a s...

Embodiment 2

[0032] Such as figure 2 As shown, the black and white film includes a white structural layer 110 , a black structural layer 120 and an adhesive layer 130 . The white structural layer 110 is disposed between the black structural layer 120 and the adhesive layer 130, and the white structural layer 110, the black structural layer 120, and the adhesive layer 130 are formed by coating connected to each other. The adhesive layer provided in the black and white film can meet the functions of fixing, shading and light reflection of the frame of the light source of the display part, etc., and widens the application range of the black and white film. The functions and effects of other parts in this embodiment are the same as those in Embodiment 1, so they will not be repeated here.

Embodiment 3

[0034] Such as image 3 As shown, the black and white film includes a white structural layer 110 , a black structural layer 120 and an adhesive layer 130 . The adhesive layer 130 is disposed between the black structural layer 120 and the white structural layer 110, and the white structural layer 110, the black structural layer 120 and the adhesive layer 130 are formed by coating connected to each other. The adhesive layer provided in the black and white film can meet the functions of fixing, shading and light reflection of the frame of the light source of the display part, etc., and widens the application range of the black and white film. The functions and effects of other parts in this embodiment are the same as those in Embodiment 2, so they will not be repeated here.

Abstract

The invention discloses a black and white film which comprises at least one white structure layer and one black structure layer. In the invention, the structure and the composition of the black and white film are optimized, so the black and white film has the advantages of excellent shading effect, light resistance, complete satisfying of shielding demands of parts in a display apparatus, smooth and flat surface, no fading, and good high temperature dimensional stability, and the white surface has an excellent light reflection effect, thereby lights emitted by a backlight source can be fully and effectively utilized to improve the display effect of a liquid crystal display panel. An arranged bonding layer allows the fixation, the shading and the light reflection effects of display part light source frames and the like to be further satisfied, and the black and white film which has an excellent molding processing performance can satisfy various molding processing demands.

Description

technical field [0001] The invention relates to a film, in particular to a black and white film. Background technique [0002] In recent years, liquid crystal display technology has been widely used in electronic products in various fields of life, such as: mobile communication equipment display, computer / TV display, touch panel, monitor, GPS display, MP3 / MP4, etc. However, since the liquid crystal itself does not emit light, the liquid crystal display panel must rely on the backlight source to provide it with sufficient brightness and evenly distributed light sources, so that the liquid crystal display panel can display images normally. [0003] However, with the wide application of liquid crystal display technology, the requirements for the performance of liquid crystal display panels are also increasing day by day, mainly focusing on improving the brightness. At present, for the improvement of the display brightness of the liquid crystal display panel, it largely depends...
