Advanced MVA (A-MVA) - Next Generation VA Technology
AU Optronics have recently been working on their next generation of MVA (Multi-Domain Vertical Alignment) panel technology, termed 'Advanced MVA' (A-MVA). This is designed to offer improved performance including reduced colour washout conquer the significant problem of color distortion with traditional wide viewing angle technology. This technology creates more domains than conventional multi-domain vertical alignment (MVA) LCDs and reduces the variation of transmittance in oblique angles. It productively improves color washout and provides better image quality in oblique angles than conventional VA LCDs. Also, it has been widely recognized worldwide that AMVA technology is one of the few ways to provide optimized image quality through multiple domains.
In addition, A-MVA provides an extra-high contrast ratio of greater than 1200:1 (reaching 2500:1 at time of writing) by optimized color-resist implementation and a new pixel design. The result is a more comfortable viewing experience for the consumer, even on dimmer images. This high contrast technology can also achieve wide viewing angles of up to 178 degrees. AMVA, which the Company believes to be the most competitive solution in low color washout technology, has been applied to AUO TV panels ranging from 32" up to 42", and has attracted widespread attention among global brand-name TV customers in the United States, Europe and Japan.
Simulated Pulsed Driving' (ASPD) - Motion Blur Reduction
AUO's 'Simulated Pulsed Driving' (ASPD) technology is designed to solve the issue of motion blur in liquid crystal displays. AUO's Simulated Pulsed Driving (SPD) technology simulates impulse-type displays with the adjustment of pixel driving and scanning backlight to reach a CRT-like image quality in motion picture response time. The technology can greatly reduce motion blur, and enable the image performance to reach optimal levels at 4ms equivalent gray to gray (8ms MPRT). The technology is also known as one of the few technologies ready for mass production and can be applied both to WXGA (1366x768) or Full HD (1920x1080) resolutions.
HiColor Technology and LED Backlighting - Improved Colour Richness and Gamut Range
The new HiColor Technology with LED backlight can reach 105% NTSC ? a 45% increase from conventional 72% NTSC. It also provides the true natural performance of Red, Green and Blue and enables brighter, richer, and more vivid display colors. In addition, AUO has adopted specific techniques to enhance the image performance of the LED backlight. The Color Management function can eliminate artificial colors caused by inconsistent chromaticity between light source and signal. The Gamut Enhancement function enhances and enriches colors. The Flexible Color Temperature Setting can change the intensity of the RGB LED to adjust the white point of backlight and meet the requirements of different applications with minimal luminance loss. Other advantages of LED backlights include instant light, low DC voltage, shock and vibration safe, fast response time, low temperature start, and an environmentally-friendly design that is both mercury and lead free.
AUO Picture Enhancer (APE) - Providing Sharp, Vivid Images and Clear Depth of View
This technology is designed to offer natural color images and clear depth of view. AUO's Image Processing Technology integrates the input image data management and the dynamic backlight control solution. The intrinsic image processing system circuit can dynamically adjust the contrast, sharpness, hue, color temperature, and color saturation to accommodate the image contents. Non-linear image processing can accommodate changes in the dynamics of human perception ideally used to overcome an existing problem with LCD TVs where a motion picture tends to loose its accuracy during darker states. AUO's Image Processing Technology enables vivid and sharp images, enhances color saturation, details in gray levels and contrast ratios, and retrieves natural colors. An added value of this technology is its energy and environmental conservation abilities as its dynamic backlight control function can automatically adjust the CCFL brightness.
Large-sized products will place emphasis on A-MVA technology with super wide viewing angle, HiColor technology with the achievement of color saturation, and ASPD technology with great motion picture quality; while medium-small sized- products will focus on high resolution and wide viewing angle. The BenQ VL4233 LCD TV (42" model) is expected to be the first featuring the new A-MVA panel technology. This will offer a spec of 8ms response time, 1200:1 contrast ratio, 500 cd/m2 brightness and 178/178 viewing angles. As a reminder, AUO form part of the BenQ group, and so will be in the front-runners of those using the newly devloped technologies.
