Light-emitting diodes (LEDs) are increasingly being used in flat panel display (FPD) backlights and general lighting applications. Although this is not news, it poses a problem for engineers: Which of the various existing LED backlight technologies is best suited for their design?
Each technology is advertised for maximum brightness, optimal image quality and uniformity, lowest power consumption and lowest cost, and provides the most efficient application for current LEDs; however, how can it solve the problem? This problem for engineers depends on the specific application, key indicators, and the original functionality of the backlight and lighting technology. In this regard, fiber optic technology has been recognized as one of the best technologies that can be applied to a particular display application in all respects.
In fact, not all large-size FPD applications, like LCD TVs and digital signage, must have a full-color display with full-motion video. For example, the operating interface of test instruments and membrane switches typically uses a smaller passive matrix monochrome liquid crystal display (LCD). For test instrumentation, motor controllers, and handheld data acquisition device manufacturers, they are concerned with the brightness and uniformity of the display: it must look good. However, these applications are often produced in medium and small quantities, and the inventory module cannot be used. The important considerations are low power consumption, no heat generation, no electromagnetic radiation interference, thin profile and low tool cost, and a multi-purpose function for passengers. The technology of industrial design.
If a fiber optic panel made of plastic fiber or a multi-row fiber mounted on a back reflector, the resulting backlight provides an easy-to-import, easy-to-customize solution that allows OEMs to achieve high quality The backlights are integrated into their devices without increasing customer costs.
More and more membrane switch OEMs are increasingly adopting backlights to improve their user interfaces and increase the value of the entire device to their customers. Of course, functionality is still important, such as thermal and ESD protection, and the feel of the switch itself. Fiber optic panels made from multiple rows of fibers can be placed between the cover layer and the switch layer, allowing only a single LED to provide a wide range of uniform illumination and superior tactile feel.
In addition, designers can use a rare non-rectangular geometry, including holes and other irregular shapes. Traditionally this has dominated the field of cold light (EL) backlights, but fiber optic technology offers the industry's expectations for brightness, uniformity, durability and low power consumption, and without electromagnetic interference/radio frequency interference to degrade brightness and correlate with EL Fiber converter technology has received much attention.
In addition to LCD and membrane switch backlight applications, the versatility of fiber optic technology extends its reach to the field of lighting. In a water environment such as an advanced spa and an open-air swimming pool, backlighting and brightness of the control panel can be achieved by embedding a new generation of high-power LEDs into the fiber optic 'light engine'. This light engine has a special collimating lens that captures the light from the LED and focuses the light onto the fiber optic panel. Optical fiber optic lines can also be used in self-service DVD karaoke equipment to provide bright, color-smoothed singers or indicators that direct the user's attention to retrieval and recovery without the need for additional space, depth or directory environment changes. . As OEMs become more aware of the diverse functional characteristics of fiber optic lighting technology, more related applications are being developed.
