Unlock your LCD's potential, through energy saving, Passive Film Enhancements.
AGDisplays provides optical film enhancements for notebook and desktop LCD's, industrial LCDs and LCD televisions. Our products can be retrofitted into any LCD to increase the efficiency of existing visual technology. High bright enhancements increase brightness by 40 to 145 percent and intensify the display's contrast, while anti-glare enhancements minimize reflections from ambient lighting noticeably improving readability. We maintain state-of-the-art clean room facilities equipped with a tab bonder, automated laminating and temperature controlled de-laminating equipment.
AGDisplays enhancements provide
- Bright display without an increase in power
- Increased side-view abilities
- Increased display contrast and readability
- Resistance to scratches and contaminants
- Increased display clarity and image quality
Privacy of information
- Increased color sharpness
Our team knows that LCD's panel manufactures use various configurations of optical films to direct, brighten, and diffuse the light produced from the backlight source. The process of installing additional optical films can increase the brightness with no increase on the LCD's power consumption. For systems requiring lower power use, film enhancement can be developed to achieve the targeted brightness level using lower power consumption.
Evaluating and analyzing the panel's stock film stack is a crucial step in determining the most effective passive film enhancement. Our experienced technicians will evaluate and suggest the best recipe available to optimize brightness. With so many film manufactures in the industry AG Displays stocks a wide range of brightness enhancement film that enables our techs to determine the proper enhancement configuration. While the addition of brightness enhancement film can achieve a brightness increase, many times multiple configurations can be assessed to allow the customer several options in pricing and overall brightness levels.
AG Displays implements stringent policies and procedures for our Class 1,000 clean rooms. This assures that all enhancement processes produce the desired outcome for our customers, while maintaining the integrity of the LCD panel. AGDIsplays performs multiple quality tests during the enhancement process. Our final QC assures the quality and workmanship of every LCD meets our required values.
Brightness Enhancement Film (BEF)
Brightness enhancement film or BEF film can increase the brightness of liquid crystal displays through improved management of the existing light produced by the backlight. The prisms on the brightness enhancement film redirect light from the backlight toward the LCD user. BEF Film utilizes refraction and reflection to increase the efficiency of your backlight source, regardless of the source (CCFL or LED). BEF Film allows light to exit the LCD at a specific angle. Light outside of this angle is reflected back into the LCD until it exits at the proper angle. Multiple BEF films used in unison can absorb and reflect light from both the 0 and 90 degree absorption angles and can increase the light output while maintaining the recommended current draw of the stock LCD.
Dual Brightness Enhancement Film (DBEF)
Another tansmissive film used to increase brightness is Dual Brightness Enhancement Film or DBEF as it is commonly referred to. DBEF is a thin film reflective polarizer that captures and uses light normally lost to absorption in the bottom LCD polarizer and redirects it until allowing it to exit the LCD backlight assembly at the proper angle. Using DBEF film in conjunction with BEF film can often offer the highest yield of light output. The correct mating of BEF and DBEF films is critical when designing a film enhancement to assure the maximum return is achieved. Multiple version of DBEF film is available which allows the correct film to be chosen for each specific application. AG Displays stocks multiple version of this film so we can quickly identify, and implement the correct solution, resulting in less time loss during the engineering stage of development.
DBEF works through polarization recycling. The diagram below shows a conventional backlit system emitting P1 and P2 light. A typical bottom glass polarizer absorbs P2 light, but Vikuiti DBEF reflects P2 into the backlight, where it is recycled into P1 and P2 light. With Vikuiti DBEF, more P1 light is available to be transmitted through the LCD, increasing on-axis illuminance by up to 60% for a slab backlight and up to 97% for a wedge light guide. Vikuiti DBEF achieves additional on-axis illumination performance in a wedge backlight display by redirecting available light to the LCD user.
Enhanced Specular Reflector (ESR)
ESR is an acronym for Enhanced Specular Reflector which is a film placed in the backlight cavity and is a 100% polymer film with a reflectivity of 98.5% across the visible spectrum. This non-metallic thin film construction lends itself to incorporation into a wide variety of configurations and applications. This film used in conjunction with other brightness enhancing films can obtain the highest light output especially when designing a solution for use in direct sunlight light.
