Quick view

The Sharp Aquos Quattron LC-70LE857U is a 70-inch LED-backlit LCD television featuring Sharp's proprietary Quattron technology, which adds a fourth primary color (yellow) to the traditional RGB spectrum for enhanced color reproduction. It supports 1080p Full HD resolution with active 3D capabilities, including 120Hz refresh rate for smooth motion and reduced crosstalk in 3D playback. The display panel utilizes LED backlighting that allows improved contrast ratios and energy efficiency compared to CCFL-backlit models. Additionally, this model includes an advanced video processor for upscaling lower resolution content and managing motion interpolation. It has multiple HDMI inputs and supports various multimedia formats for flexible connectivity and media playback. This model also features integrated Wi-Fi and Ethernet ports for smart TV functionality and internet access.

The Quattron technology with an additional yellow subpixel boosts color accuracy and vibrancy beyond standard RGB displays. Its large 70-inch screen size offers an immersive viewing experience suitable for home theaters. Active 3D support provides a more engaging 3D viewing without ghosting artifacts, leveraging the 120Hz refresh rate. LED backlighting ensures better contrast, brightness uniformity, and reduced power consumption. Smart TV capabilities enable access to streaming apps and online content directly. The inclusion of multiple HDMI ports and USB inputs provides excellent connectivity options for varied multimedia devices.

The LC-70LE857U is relatively bulky and heavy compared to modern slim TVs, making wall-mounting somewhat challenging. Its 3D technology requires specialized glasses, which can be an additional cost and usability concern. The smart TV platform may be outdated with limited app availability compared to newer models. Despite the Quattron technology improving color gamut, it may not match the accuracy and HDR performance of newer LED or OLED displays. The energy consumption, although better than older CCFL models, is higher than current energy-efficient TVs. Lastly, the TV lacks 4K resolution support, which has become the standard in recent years.
