20100013785 | DISPLAY PANEL SUBSTRATE, DISPLAY PANEL, DISPLAY APPRATUS, AND METHOD FOR MANUFACTURING DISPLAY PANEL SUBSTRATE - A display panel substrate according to the present invention includes at least an insulating substrate, first conductive wires formed on the insulating substrate, a piezoelectric material film formed on the first conductive wires, second conductive wires intersecting with the first conductive wires, and a protecting film for protecting the first conductive wires, the second conductive wires, and the piezoelectric material film. The insulating film is formed at least in an area in an effective display area on the insulating substrate. The piezoelectric film is formed at least at an intersection of a first conductive wire and a second conductive wire. This makes it possible to provide a display panel substrate that allows integration of a touch panel function into a display panel without causing an increase in size of the display panel. | 01-21-2010 |
20100118058 | DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - In one embodiment of the present invention, an active-matrix type display unit, and a drive method thereof are disclosed. Gate-bus lines are provided at both top and bottom sides of each row. Two sub-pixels are formed at a region surrounded by two adjacent source-bus lines and two adjacent gate-bus lines. At the odd-numbered rows, for the left-side sub-pixel of those two sub-pixels, a scanning signal is supplied from the top-side gate-bus line, while a video signal is supplied from the left-side source-bus line. For the right-side sub-pixel, on the contrary, a scanning signal is supplied from the bottom-side gate-bus line, while a video signal is supplied from the right-side source-bus line. At the even-numbered rows, the gate-bus line from which a scanning signal is supplied is reversed to the case of the odd-numbered rows. The gate-bus lines are sequentially selected one by one, and all the video signal polarities are made the same during each horizontal scanning period. | 05-13-2010 |
20100134473 | LIQUID CRYSTAL DISPLAY DEVICE - In a liquid crystal display device performing alternating-current driving, at least one of a gate voltage amplitude Vgp−p(p) upon application of a positive polarity voltage and a gate voltage amplitude Vgp−p(n) upon application of a negative polarity voltage is changed in accordance with a liquid crystal driving frequency. Thus, an effective value of a liquid crystal application voltage in a positive polarity is set to be equal to an effective value of a liquid crystal application voltage in a negative polarity irrespective of the liquid crystal driving frequency, so that flicker is prevented from occurring when the liquid crystal driving frequency is switched. As the liquid crystal driving frequency is low, a gate low voltage Vgln after application of the negative polarity voltage is set to be low. Thus, a leak current from a TFT is reduced in the negative polarity, and a liquid crystal element is improved in voltage holding ratio. | 06-03-2010 |
