Embodiment 1

[0070] Such as figure 1 As shown, the embodiment of the present invention provides an image quality improvement film, see figure 2 , the image quality improvement film is used to be pasted on the side surface of the display layer 1 of the display panel for displaying the picture, and the image quality improvement film includes a scattering layer 2, and the scattering layer 2 is used to cover the pixels of the display layer 1 The area 11 is used to scatter light from the display layer 1 .

[0071] Such as figure 2 As shown, the image quality improvement film provided by the embodiment of the present invention is used to be pasted on the side of the display layer 1 of the display panel for displaying the picture, and the scattering layer 2 covers the pixel area 11 of the display layer 1 . In the embodiment of the present invention, the image quality improvement film provided by the embodiment of the present invention is used as an example to be attached to one side of the di...

Embodiment 2

[0086] Such as Figure 10 As shown, the embodiment of the present invention provides a method for preparing an image quality improvement film, the image quality improvement film is used to be attached to the side of the display layer of the display panel for displaying the picture, and the image quality improvement film The preparation method comprises the steps:

[0087] In step 101, a scattering layer is formed, and the scattering layer is used to cover the pixel area of ​​the display layer to scatter light from the display layer.

[0088] In the embodiment of the present invention, the outer contour size of the scattering layer is greater than or equal to the size of the pixel area of ​​the display layer of the display panel, and the light from the display layer is scattered after entering the scattering layer, thereby increasing the oblique viewing angle of the display panel.

[0089] In the present invention, the image quality improvement film is attached to the side sur...

Embodiment 3

[0091] Such as Figure 11 As shown, the embodiment of the present invention provides a method for preparing an image quality improvement film, the method comprising the following steps:

[0092] In step 201, the liquid crystal, polymerizable monomer and photoinitiator used to prepare the scattering layer are mixed according to the following mass percentage:

[0093] The mass percentage of the liquid crystal is 70% to 80%, the mass percentage of the polymerizable monomer is 19% to 29.5%, and the mass percentage of the photoinitiator is 0.3% to 1% of the mass percentage of the polymerizable monomer;

[0094]In the embodiment of the present invention, preferably, the liquid crystal is a nematic liquid crystal, and the polymerizable monomer is an acrylic monomer. Those skilled in the art can understand that the types of the liquid crystal and the polymerizable monomer can be specified according to the mode of the display panel. Determine, the mass percentage of each material in t...

Abstract

The invention discloses an image quality improving film, a preparation method thereof, a display panel and a display device, and belongs to the field of display technology. The image quality improving film includes a scattering layer for covering a pixel area of ​​the display layer to scatter light from the display layer. In the present invention, the image quality improvement film is attached to the side surface of the display layer of the display panel for displaying the picture, and the scattering layer of the image quality improvement film covers the pixel area of ​​the display layer, and the light from the display layer is scattered by the scattering layer, thereby The oblique viewing angle of the display panel is increased to meet the needs of users.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an image quality improvement film and a preparation method thereof, a display panel and a display device. Background technique [0002] Due to the advantages of lightness, thinness, low power consumption, high brightness and high image quality, display panels are widely used in various electronic devices such as monitors, tablet computers and smart phones. Wherein, the display panel includes a liquid crystal layer, and the liquid crystal molecules in the liquid crystal layer are an anisotropic substance, so that when the angle of the oblique viewing angle reaches a certain value, the viewer cannot see the picture on the display panel. [0003] The oblique viewing angle of the existing display panel can only reach 45 degrees, that is, only when the angle between the line connecting the observer and the center of the display panel of the display panel and the normal line of the di...
