HP’s giant 42-inch multi-touch LCD, the LD4200tm

HP just announced its new LD4200tm, a 42-inch LCD that can handle multi-touch inputs. HP has positioned this device for businesses, so you may see this in a hotel near you soon. This display has a resolution of 1920 x 1080 and uses “an array of infrared (IR) light-emitting diodes (LEDs), along with photo sensors, to determine touch by pairing to create a grid of light beams across the display. When an object (such as a finger, pen or any other pointing device) touches the screen, the light beam within the grid is interrupted and thus, touch is recognized.” In other words, this display won’t be using your usual capacitive or resistive technologies for its touch screen. There’s no information as to the pricing of this thing, but since it’s for businesses, don’t expect to be adding this to your home any time soon. The LD4200tm is also designed to run 24-hours a day, 7 days a week.
