Abstract
Various methods and systems are provided for a self-sanitizing touchscreen in a liquid crystal display of a medical device. In one example, ultraviolet light of a first wavelength may be generated from one or more light emitting diode (LED) engines positioned along a perimeter of the touchscreen or integrated in the LCD assembly to sanitize the touchscreen, the ultraviolet (UV) light flooding the touchscreen to sanitize the touchscreen.
Claims16
A system for a LCD assembly of a medical device, comprising:
- a touchscreen panel including a frame lining a perimeter of the touchscreen panel, the touchscreen panel configured to be used by an operator during operation of the medical device;
- a series of LED engines integrated in the frame of the touchscreen panel, the series of LED engines being configured to generate ultraviolet (UV) radiation of a first wavelength;
- and
- a series of optical lenses corresponding to the series of the LED engines, the series of optical lenses being configured to focus the UV radiation onto the touchscreen panel, the focused UV radiation irradiating substantially an entire surface area of the touchscreen panel facing the operator.
