  • Patent number: 7511985
    Abstract: A semiconductor memory device comprises a array of memory cells arranged in a matrix, each memory cell connected to one end of a variable resistor element where the electric resistance is shifted from the first state to the second state by applying the first writing voltage and from the second state to the first state by applying the second writing voltage, and the source or drain of the selecting transistor. The second writing time for the second writing action of shifting the electric resistance of the variable resistor element from the second state to the first state is longer than the first writing time of shifting the same reversely. The second number of the memory cells subjected to the second writing action at once is greater than the first memory cell number subjected to the first writing action at once, and at least the second number is two or more.

  • Patent number: 7511772
    Abstract: When a video signal type detecting section detects a video signal of PAL/SECAM (50 Hz) video signal, the input image data is subjected to enhancing conversion with a degree lower than the degree of enhancing conversion in the case of NTSC (60 Hz). With this, the response speed of liquid crystal is improved and an image noise on account of excessive enhancement is eliminated, so that the deterioration in image quality is prevented. As a result, the enhancing conversion with respect to the input image data is performed in such a manner as to compensate the optical characteristics of the liquid crystal display panel, and an image noise on account of excessive enhancing conversion with respect to PAL/SECAM (50 Hz) image data, and hence high-quality image display is realized.

  • Patent number: 7511708
    Abstract: A display device in accordance with the present invention changes to Vc the voltage of a terminal of a capacitor C2 the other terminal of which is connected to the gate of a driver TFT Q1. Thus, a desired voltage Vda is fed from a source line Sj to the drain of the driver TFT Q1 so as to adjust the threshold voltage Vth of the driver TFT Q1. The device then changes the voltage of the terminal of the capacitor C2 to Va to render the gate voltage of the driver TFT Q1 Vda-Vth-Vc+Va. A power supply voltage Vp is fed from the source of the driver TFT Q1.
