AI Technical Summary
Technical Problem
Current automotive display designs face challenges in achieving the required viewing angles and brightness while minimizing power consumption, as existing prism sheets concentrate light rays along direct vision and increasing brightness for wider angles leads to significant energy loss.
Method used
An optical film with specific prism structures and array densities that divert light into different viewing angles, maintaining brightness and reducing power consumption by optimizing light distribution.
Benefits of technology
The optical film expands the viewing angle to meet automotive display standards without increasing overall brightness, thereby reducing energy consumption and enhancing visibility from various seating positions.

Abstract
The present disclosure relates to an optical film (100), an optical film group (600), a backlight module (200), and a display device (900). The optical film (100) comprises a main body (110), a plurality of first prism structures (120), and a plurality of second prism structures (130). The main body (110) has a first optical surface (111) and a second optical surface (112) facing each other. The first prism structures (120) are disposed on the first optical surface (111). Each of the first prism structures (120) has a first extension direction (D1). The second prism structures (130) are disposed on the second optical surface (112). Each of the second prism structures (130) has a second extension direction (D2). The first extension direction (D1) is different from the second extension direction (D2).
