A touch-sensing display screen includes an upper transparent substrate, a lower substrate opposite the upper substrate, and a backlight unit having an infrared light source configured to radiate infrared light through the upper substrate in a first direction. A transparent window is disposed in alignment with the infrared light source and between the upper and lower transparent substrates. A portion of the infrared light radiated in the first direction is reflected back through the upper substrate and through the transparent window in a second direction by an object touching a surface of the upper transparent substrate. A pixel thin-film transistor on the lower substrate is configured to activate a pixel electrode, and an infrared light-sensing thin-film transistor is configured to sense the infrared light received through the upper substrate in the second direction, and output an infrared light-sense signal in response thereto.
