Customize Prism Sheet
Brightness enhancement film (BEF) is an optical film with a uniform prism pattern formed by acrylic resin on the surface of PET with very high transparency. It is generally used with upper and lower layers (i.e. horizontal and vertical stripes) to enhance brightness orthogonally. It is assembled on the front of the backlight source to focus the light emitted by the light source toward the user of the display device. In addition, the unused light outside the viewing angle is recycled according to the re-reflection effect of light and focused toward the user at the most appropriate angle.

what is prism sheet?
Brightness enhancement film is a core component of the display screen. It refers to a film or sheet in the TFT-LCD backlight module that can improve the luminous efficiency of the entire backlight system.
Brightness enhancement film is also called prism sheet according to its microscopic prismatic structure. It can also be called brightness enhancement film according to the process of correcting the direction of light to achieve the brightness enhancement effect. It is also often referred to as BEF.
Brightness enhancement film is a transparent optical film composed of a three-layer structure. The light-incoming surface of the bottom layer needs to provide a certain degree of haze through back coating; the middle layer is a transparent substrate layer; the light-emitting surface of the top layer is a micro-prism structure.
advantages of prism sheet
1. Improve light output efficiency:
- BEF can refract and guide the light from the backlight source, focusing more light on the area that needs to be illuminated.
- This can improve the overall light output efficiency and reduce light source waste.
2. Enhance brightness and uniformity:
- BEF can evenly distribute light and reduce the difference between local bright and dark areas.
- This can improve the overall brightness and uniformity of the display or lighting equipment and improve the visual effect.
3. Control light angle:
- The microstructure inside BEF can change the angle of light emission.
- This can adjust the angle of light projection according to needs, such as controlling the viewing angle in LCD screens.
4. Reduce glare and reflection:
- BEF can effectively eliminate the glare of the light source and reduce reflection and scattering.
- This can improve the contrast and clarity of the display or lighting equipment.
5. Strong compatibility:
- BEF is compatible with various light sources and optical structures, and is easy to integrate into different lighting and display products.
- This makes BEF widely used in LCD, LED, OLED and other fields.
pruduce process of prism sheet
1. Material selection
- Usually use optical grade plastic raw materials with high light transmittance and good wear resistance such as polycarbonate (PC) and polymethyl methacrylate (PMMA).
2. Extrusion film
- The plastic raw material is heated and melted by an extruder, and then continuously extruded into film through special molds and rollers.
- This step can produce a flat and smooth base film.
3. Microstructure processing
- Use precise embossing or replication technology on the surface of the base film to produce microscopic optical structures.
- These microstructures can refract and guide light, thereby exerting the optical function of BEF.
4. Cutting and finishing
- Cut the continuously manufactured BEF film and divide it into products of the required size.
- Inspect, package and sort the finished products to ensure that they meet the quality requirements.
5. Coating treatment
- Sometimes it is necessary to perform special coating treatment on the surface of BEF, such as anti-glare, anti-scratch and other functional coatings.
- The coating can further improve the performance and service life of BEF.
6. Quality Control
- Strict quality inspection and monitoring will be carried out in all aspects of production to ensure stable and reliable product performance.
- Including testing and verification of multiple indicators such as optical performance, mechanical strength, and weather resistance.
Application scenarios of prism sheet
1. Liquid Crystal Displays (LCDs):
- BEF is a crucial component in LCD backlighting systems, helping to improve the brightness and uniformity of the display.
- By controlling the angle and distribution of light, BEF enhances the overall luminance and contrast of LCD panels.
2. Light-Emitting Diode (LED) Lighting:
- BEF can be used in LED-based lighting fixtures to optimize the light output and directionality.
- It helps to create more uniform and efficient illumination by managing the LED light rays.
3. Automotive Lighting:
- BEF is employed in various automotive lighting applications, such as headlights, taillights, and interior lighting.
- It helps to shape the light beam patterns and improve the overall lighting performance.
4. Signage and Advertising Displays:
- BEF is utilized in illuminated signs, billboards, and other types of advertising displays to enhance brightness and visibility.
- It ensures consistent and eye-catching lighting effects across the display surface.
5. Backlit Keyboards and Keypads:
- BEF is used in backlit keyboards and keypad applications to provide even and comfortable illumination.
- It helps to eliminate hot spots and dark areas, improving the overall aesthetics and usability.
6. Optical Sensors and Detectors:
- BEF can be integrated into optical sensor systems, such as those used in security cameras or industrial automation.
- It helps to optimize the light collection and distribution, improving the performance and sensitivity of the sensors.
