non glare lcd panel factory
Dazzle is the side effect of lighting. It happens when the surrounding light isstronger than that of the screen, which makes user uncomfortable when usingthe cellphone, Pad, and so on. The newly developed technology – AG(Non-Etching)- to decrease it.
For everything from the increasingly popular kiosks found in shopping malls, retail stores, and commercial outdoor settings, to sophisticated medical instruments used in sterile operating rooms, LCD"s, or Liquid Crystal Displays, are the preferred user interface for displaying data. However, if steps are not taken to control glare caused by bright natural and artificial light and the smudging that can occur with normal handling and touching, as well as protect against conditions in nature, display visibility can become a serious problem.
Clear display visibility is mission critical for Apollo Display Technologies, LLC, specialists in flat panel LCD manufacturing. "Our displays are used in all sorts of environments under all kinds of conditions," says Richard McKay, Manager of Value Added Technology, a15-year veteran in the flat panel industry. "No matter where or how they are used, they must be easily readable at all times. Our clients absolutely cannot tolerate glare or smudging that could interfere with visibility," says McKay.
To meet its customers" needs to minimize glare on LC displays, the company specifies protective overlays made of ACRYLITE Anti-Reflective acrylic sheet manufactured by CYRO Industries. Anti-reflective acrylic not only has outstanding light transmission and glare reduction properties, but can also be coated with a variety of special materials to protect it from the environment.
"Apollo Display is a unique animal in the display industry," says McKay. "As LCD specialists, we"re nimble and adaptable enough to satisfy customers with just about any application." Indeed, Apollo creates LCD displays for indoor and outdoor kiosks, ATMs, automotive displays, and medical and military instrumentation, among many other applications.
Unlike flat panel distributors who outsource everything, Apollo focuses strictly on displays and does all of its manufacturing in-house. This includes designing and manufacturing its own controller electronics and creating LCD upgrades and laminations in its specially designed clean rooms.
All of its LC displays are not only used in glare-inducing environments, but many are interactive and frequently touched by the people using them. In addition, in some instances, like marine or military applications, they can be exposed to severe weather conditions and corrosive or oily substances.
The rapidly growing indoor and outdoor kiosk business represents 25 percent of Apollo"s sales, and retail store and shopping mall kiosks are becoming increasingly popular. "Retailers recognize the value of a sophisticated, high-end looking kiosk that grabs the attention of customers and pulls them into their stores, or functions inside the store as a value-added high-tech marketing tool," says McKay. To cater to the kiosk market, Apollo designs and manufactures open frame LCD monitors that can be dropped right into the finished kiosk, eliminating the need for individual components and flat panel integration, enabling retailers to have the display up and running immediately.
Because kiosks are used by the general public, some kind of screen protection is absolutely necessary. "The display is the most expensive component in the kiosk and the screen needs to be able to withstand use, and abuse," says McKay. "But, at the same time, the acrylic sheet and protective coating cannot degrade the quality of the image on the screen. And because kiosks are often positioned directly beneath bright store lights and natural light we must also prevent glare."
"We found anti-reflective ACRYLITE best for retail kiosk applications because it"s tough enough to hold up to someone hitting it with a hard object like an umbrella handle, ring or bottled beverage," he says. "It maintains its clarity in natural and man-made lighting. And the anti-reflective coating, which is on both sides of the sheet, eliminates glare and enhances the readability of the display," says McKay. Coated on one side, ACRYLITE Anti-Reflective sheet transmits 94 percent of visible light. Coated on both sides, it transmits 97 percent.
Apollo uses various methods to "high bright" indoor and outdoor displays which increases the brightness of stock LCD"s. A 10.4-inch display, for example, has a typical brightness of 350 nits, or candellas (a unit of light measurement) per meter squared, which is the standard for light output for all LCDs. Upgrading the light output of the panel and its backlighting system can increase this to 500 or even 850 nits. At this level of brightness, the display is more easily readable under high ambient lighting conditions," "Laminating the ACRYLITE Anti-Reflective sheet to an LCD maintains its brightness of about 350, 500 or 850 nits and further enhances readability in these extreme lighting conditions" he says.
Another major market for LCD"s is medical instruments and other devices, which are often used in operating rooms that are brightly lit to afford doctors the best view of the operating field. Thirty percent of Apollo"s business is in the medical market. "Surgeons must be able to read displays instantly, often from awkward or uncomfortable angles," McKay notes. "Any glare from the operating room lights is simply unacceptable. Anti-reflective ACRYLITE virtually eliminates the glare, allowing us to enhance the display for even better visibility, even under the intense operating room lights."
One of the areas in which Apollo is experiencing rapid expansion is in the casino gaming market. "Successful games are usually produced in quantities of two to five thousand units. At this high volume of material, cost is critical. Glass is not only heavy, it"s prohibitively expensive. Plus, the screens need to be protected against glare and frequent handling. Anti-reflective acrylic has been ideal for addressing this business," says McKay.
Color gamut is a measure of how many colors can be represented on a display. The higher the color gamut, the more colors represented, making color more rich and saturated. While no display can come close to what is seen with the human eye, a 100% color gamut panel is the best available in PC display. When a panel is 100% color gamut, it’s typically described as Adobe RGB. The XPS 15 4K Ultra HD display is factory color measured and color coordinates are saved onto the panel so you can reproduce color accurately. They are vivid, show more shades, higher saturation and more colorfulness. The user sees a more pleasant, colorful and accurate image. The XPS 15 and 17 are the only laptops that are true 100% minimum Adobe RGB, meaning the panel can represent all color in the Adobe color space without compromise. Professionals are able to get a full color representation of their content in the field - they can take a photo with an RGB setting on their camera, use Adobe software, and see that image on their display with exactly the same colors represented.
A laptop with high brightness is easy to see when using outdoors & prefect for watching movies or web surfing. A 500-nit panel, found on XPS laptops, is brighter than a typical laptop panel (200-nit).
Navigation made easy. A panel with multi-touch allows users to interact with their multimedia by directly touching the computer LCD, minimizing the need for a keyboard, touch pad or mouse. A touch screen is a more natural way to interact with your PC. You have the freedom to just touch the screen and manipulate directly. Plus, it is a more collaborative experience — no fighting over the mouse or who has control of the screen. And two people can interact with one application at the same time, with up to ten-finger-touch functionality.
