Abstract:
An LCD(Liquid Crystal Display) panel using solar cell pixels and an LCD are provided to reduce power consumption of the LCD by using natural energy as driving power of an LCD. An LCD panel(100) includes red, green and blue liquid crystal pixels and a solar cell pixel which are arranged in a matrix form. The solar cell pixel has the same area as those of the red, green and blue pixels. The red, green blue pixels and the solar cell pixel are arranged in a 4x1 matrix or a 2x2 matrix. The solar cell pixel outputs an electric signal proportional to the intensity of incident light. An LCD includes a display module and a solar cell module. The display module includes red, green and blue liquid crystal pixels formed on a substrate. The solar cell module is located at the side of the display module and includes a solar cell pixel which generates power using incident light.

Abstract:
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.
