  • Temperature sensor for a liquid crystal display panel
    Patent number: 7425725
    Abstract: A sensor is provided, which includes a substrate, an insulating layer formed on the substrate, a semiconductor formed on the insulating layer, an ohmic contact formed on the semiconductor, a sensor input electrode and a sensor output electrode formed on the ohmic contact, and a passivation layer formed on the sensor input electrode and the sensor output electrode. A sensor control electrode may also be formed between the substrate and the insulating layer. A thin film transistor array panel including the sensor and a liquid crystal display panel including the sensor are further provided.

  • Liquid crystal display apparatus, light-sensing element and apparatus for controlling luminance of a light source
    Publication number: 20060118697
    Abstract: A liquid crystal display apparatus includes an LCD panel assembly. A backlight assembly includes a light source that irradiates the LCD panel assembly. A light-sensing part generates a detection signal corresponding to a quantity of the light. A reference signal-generating part generates a reference signal corresponding to a reference quantity of the light. A control signal-generating part compares the detection signal with the reference signal to generate a control signal. A backlight assembly-controlling part controls the luminance of the light source in accordance with the control signal.
