Problems solved by technology

However, when increasing the haze and roughness of the anti-glare film to reduce glare, there will still be residual reflections of the light source, which will affect the reading screen
Furthermore, when measuring the reflected energy distribution on the surface of the anti-glare film, there will be uneven energy distribution in the central protrusion, which will affect the comfort of reading

Embodiment Construction

[0047] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. The same reference numerals refer to the same elements throughout the specification. It will be understood that when an element such as a layer, film, region or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to a physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may refer to the existence of other elements between the two elements.

[0048] It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers and / or sections, t...

Abstract

The invention discloses an optical film and a display module using the optical film. The optical film includes a rough surface that defines a virtual reference plane. In the unit measurement area, the rough surface has multiple measurement points that constitute multiple virtual measurement surfaces, and the normal vector of each virtual measurement surface has an included angle with the normal vector of the virtual reference surface. , and each measurement point has a height value with respect to the virtual datum plane, wherein on the virtual datum plane, the projected area of ​​multiple virtual measurement planes with an included angle greater than 20 degrees is between 31% and 60% of the projected area of ​​the unit measurement area, And the projected area of ​​multiple virtual measuring surfaces with an included angle greater than 50 degrees is less than 7% of the projected area of ​​the unit measuring area; the height values ​​of 25% of the multiple measuring points are greater than the first height value, and the height values ​​of 75% of the multiple measuring points The height value is greater than the second height value, and the height value difference between the first height value and the second height value is greater than or equal to 0.6 μm and less than or equal to 2.5 μm.

Description

technical field [0001] The present invention relates to an optical film; in particular, the present invention relates to an anti-glare optical film and a display module using the optical film. Background technique [0002] Flat and curved display modules have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, vehicle hosts, personal computers, digital cameras, handheld video games, and the like. However, in order to improve the user's visual experience, manufacturers are constantly improving the optical performance of the display module. [0003] For example, the display surface of some display modules may generate glare due to external ambient light during use. In most usage situations, glare often causes visual discomfort to some users and affects the optical performance of displayed images. In order to solve this problem, some known display modules add a high haze layer with a rough surface on the display surfa...
