Our revolutionary Flat Collimator Backlights, which direct all input light toward the user, can be used for backlight displays which require extremely high efficiencies. The compact size can be installed in most LCD modules with little or no modifications to the existing LCD chassis. This technology is also suitable for sunlight viewing applications. Our featured Flat Collimator Backlights include:
Dual Mode Backlighting System for Day or Night View
Using a color filter, this single light pipe backlighting system has two operational modes for day or night vision operation. The Dual Mode Backlighting System can illuminate a given display with lights of different spectrums and intensities. Output lights for both modes have the same angle. With the appropriate color filter placed between the CCFLs or LEDs and the light pipe, the Dual Model Backlighting System produces a spectrum of output light that is compatible with night vision goggles in the night vision mode.
Stacked Flat Collimator for Optimum Display Thermal Management
The Stacked Flat Collimator Backlights, which are stackable and transparent, were designed to achieve very high output brightness. The Stacked Flat Collimator is suitable for large size LCDs requiring very high brightness, excellent dimming and high efficiency.
Most traditional backlights position the CCFLs within the viewing area, so that the viewer looks directly at the CCFLs. The AMLCD is heated by the CCFLs positioned adjacent to it. Transferring heat to the backlight chassis and out of the unit is difficult.
The Advanced Micro-Prism Edge-Lit backlight, developed by BriteView Technologies, positions the CCFLs along the edge of the light guide outside of the viewing area, so that the viewer does not look directly at the CCFLs. The change in lamp placement enables heat transfer to the backlight and system chassis. The heat effect on AMLCD is negligible.
Viewing Area Expander BacklightWith a novel beam expander technology, this backlighting system can illuminate a lighting area essentially from edge to edge. This viewing area expanding technology is especially valuable for displays requiring a very limited boarder area.
Flat Collimator Using LED-Based Light Source
With the Divergent Angle Rotator technology, this backlighting system is designed using LEDs as the light source. The Divergent Angle Rotator backlight architecture can reduce or eliminate the head beams non-uniformity problem associated with a point-like light source without sacrificing brightness. The LED backlight includes white LED and RGB LED. The LED PC Board is made from an insulated metal substrate for heat management.
Color ManagementThe RGB LED Backlight uses a color management system feedback controller to provide light of the specified color coordinate or color temperature.
Heat managementBriteView designs metal chassis to dissipate heat generated by the LEDs, so that no fan is needed for the backlight.
Wide Viewing Angle Flat Collimator Backlights
This backlighting system utilizes the Divergent Angle Rotator technology to achieve a wide viewing angle of ±45°C in the horizontal direction. This feature is especially suitable for especially large display applications in which more than one person views the display. A viewing angle expanding film can be used to increase the viewing angle to over ±60°C.
Custom Design Backlighting Systems
BriteView Technologies can create custom designs to fit special display backlighting applications. In most cases, BriteView Technologies can develop prototypes in just a couple of weeks. For our customers, we have developed backlighting systems with the following requirements:
- Wide viewing angle of ±60°C in the horizontal direction
- Wide viewing angle in the vertical direction
- Peak intensity tilted towards one direction by a predetermined angle
- Backlight system without a border area, so that the total area of the backlight was the size of the display itself.
