The optical film materials for the new high brightness LCD display screen include: reflective film, quantum dot film, diffusion film, enhancing film, DBEF, and composite film.
1. Reflective sheet: It is a type of reflective sheet composed of transparent sheets that can generate reflection through its back. Its characteristics include fewer surface defects, high flatness, high reflectivity (98%), and good thermal stability.

2. Quantum dot film: It can convert about two-thirds of the blue light emitted by the backlight into pure red and green light, and then mix blue light to form high-quality white light, achieving high color gamut coverage of the display and restoring color.

3. Diffusion film: composed of a three-layer structure, including the bottom scratch resistant layer, the middle transparent PET substrate layer, and the top diffusion layer;
Diffuser film refers to a new type of high-performance optical material that solidifies optical adhesive into a pre designed optical structure diffusion layer on a PET substrate through precise coating, allowing light to diffuse through the diffusion coating, resulting in uniform distribution of light and converting point or line light sources into surface light sources.
Lower diffusion plate: 1. High shielding performance; 2. High brightness; 3. Anti scratch. Fog density: 86~95%; Light transmittance: 70-95%
Upper diffusion plate: 1. High transmittance; 2. High brightness; 3. Anti scratch. Mistiness: 40-85%; Transmittance: 96~99%

4. Zenith: It is a new type of high-performance optical thin film, due to its micro prism array structure on the surface. The light enhancing film product is a new high-performance optical material that solidifies optical adhesive into a pre designed optical micro prism structure coating through a precision coated structural micro replication method on a PET substrate, and utilizes the micro prism structure to concentrate scattered light towards the front side, thereby improving the overall brightness and uniformity of LCD panels.

5. Composite film: It is a multifunctional optical film material that uses composite technology to assemble multiple different optical films (2 or 3 types) into a single film. This product can achieve overall thinning and cost reduction of liquid crystal modules while ensuring its optical performance. At the same time, the application of composite film structure can also increase the assembly yield of backlight modules, reduce assembly time, and improve production efficiency while saving labor costs, This is an inevitable development trend for optical functional films used in liquid crystal displays.
DOP: Composite film of diffusion film and enhancement film; POP: Composite film of light enhancing film and light enhancing film; MOP: Composite film of microlens and light enhancing film; POD: Composite film of light enhancing film and diffusion film; Composite film of COP: DBEF+light enhancing film; COPP: A composite film consisting of DBEF, light enhancing film, and light enhancing film.
