4K Ultra-HD Quality The PN-70TH5 employs an LCD panel with 4K Ultra-HD (3840 x 2160-pixel) resolution. This 70-inch LCD monitor with four times the resolution of full-HD renders the textures of videos & images & reproduces the finest details of small text & intricate graphics. Besides the obvious benefits for office & educational settings the PN-70TH5 practically engulfs the viewer in highly realistic sensations & detailed accuracy. It satisfies the needs of professionals in industries such as architecture & engineering as well as in academic settings & creative sectors. Capacitive Touch Technology Sharp's original capacitive touch technology gives the PN-70TH5 highly sensitive touchscreen operation. It allows ultra-precise multiple touch inputs to be detected X & Y conductive grids etched onto layers of display. This achieves high sensitivity & precision by reducing the noise level to one-eighth of conventional models. Say goodbye to unintended input errors. You can operate & write on the screen as intended with touch pens or fingers & gain maximum benefit from its superb performance. Direct Bonding Technology Thanks to direct bonding technology the PN-70TH5 provides a consistent & natural feeling when you write on the screen. The LCD panel is bonded directly to the protective glass layer thereby eliminating the air gap between them. This minimises the parallax difference & reduces the reflection & refraction of light. As a result onscreen touch & writing operations are smooth & the display looks natural & offers clear visibility..
