  • Patent number: 8835829
    Abstract: An image sensor includes a light-sensing element, a first transistor, and a second transistor. The light-sensing element has a first end and a second end electrically connected to a select line. The first transistor has a first end electrically connected to a first control line, a control end electrically connected to the first end, and a second end electrically connected to the first end of the light-sensing element. The second transistor has a first end electrically connected to a voltage source, a control end electrically connected to the first end of the light-sensing element, and a second end electrically connected to an output line. The light-sensing element uses the material of silicon rich oxide so that the light-sensing element can sense the luminance variance and have the characteristic of the capacitor for the level boost.

  • Publication number: 20140098014
    Abstract: A liquid crystal display panel includes a pixel array, a first shift register, M first output cells, a second shift register, and N second output cells. The first register is disposed on a first side of the pixel array. The M first output cells are coupled to and next to the first shift register for providing M gate signals to M rows of the pixel array according to a first clock signal. The second register is disposed on a second side of the pixel array. The N second output cells are coupled to and next to the second shift register for providing N gate signals to N rows of the pixel array according to a second clock signal. M and N are positive integers.
