THE PRISM FILM FOR TV REPAIR
Aug 17, 2018
The brightness enhancement film is also referred to as a prism film according to the microscopic prismatic structure of the product. The process of realizing the brightness enhancement effect according to the direction of the correction light may also be referred to as a brightness enhancement film, and is also often referred to as BEF (Brightness Enhancement Film). The brightness enhancement film is a transparent optical film composed of a three-layer structure. The bottom layer of the light-incident surface needs to provide a certain haze by back coating, the middle layer is a transparent PET substrate layer, and the uppermost light-emitting surface is a microprism structure. .

working principle
The light source passes through the light-incident surface and the transparent PET substrate layer, and when the prism layer passes through the fine prism structure of the surface layer, the light intensity distribution is controlled by refraction, total reflection, light accumulation, etc., and the light scattered by the light source is concentrated toward the front. Moreover, the light that is not utilized outside the viewing angle is recycled by the reflection of the light, thereby reducing the loss of light, and improving the overall brightness and uniformity, thereby increasing the brightness and controlling the viewing angle of the LCD panel display.
The BritNit(R) series of brightness enhancement film products produced by the company refers to the optical glue solidified into a pre-designed optical microprism structure coating on a PET substrate by precision coating and structural microreplication method, and the microprism structure is used for the light. The convergence of the concentrated light is concentrated toward the front to serve as a new high-performance optical material that enhances the overall brightness and uniformity of the LCD panel.
At present, the company's production and sales of brightening film products are mainly M series and G series, which are mainly used in large display products such as desktop monitors and LCD TVs.
With the company's technical investment and experience in the key aspects of brightness enhancement film product structure and formulation design, production line key equipment manufacturing and process control, the company will continue to enrich the product line of brightness enhancement film, such as R angle series products. Small and medium-sized series products and composite film series products to meet the diversified product needs of customers
