Sharp Corporation will introduce into the Japanese market a new 32-inch-class LCD monitor, the PN-K322B. This professional-use monitor features an originally developed high-sensitivity, high-precision touchscreen and delivers 4K resolution (3,840 × 2,160 pixels)—a level of resolution four times that of full HD.

The PN-K322B is Sharp's latest ultra-high-definition display. Its high-precision touchscreen allows accurate onscreen handwriting of fine text and lines, with writing performed via a dedicated touch pen with a pen-tip width of just 2 mm. The display also supports multi-touch operation.

Thanks to IGZO technology and an edge-lit LED backlight, the PN-K322B boasts a slender profile with a thickness of just 36 mm*2—the thinnest in its class. An included stand allows the monitor to slide easily between two angles depending on the application: vertical for viewing the monitor or low-angle for onscreen writing and touchscreen operation.

The PN-K322B features a palm cancellation function that prioritizes pen input even when the user's hand is resting on the touchscreen. Input connectors on the PN-K322B are compatible with the latest DisplayPort™ and HDMI™ interface specifications, enabling the monitor to display*3 4K ultra-HD content delivered from a PC via a single-cable connection.

Demand for ultra-high-definition 4K displays is growing for numerous business and professional applications such as graphic and video content creation and editing. To further grow demand for 4K displays, Sharp will propose usage applications in other fields too, such as in customer service applications at retailers and showrooms or in exhibition displays at museums and art galleries.
