    • Input position is accurately detected. In an x-detection period of a non-display period, a source drive circuit simultaneously applies to all signal wiring lines a pulse of a peak value proportional to a distance from a gate drive circuit. A coordinate detection circuit obtains an x-coordinate on the basis of a voltage induced at a pen corresponding to the peak value (x-coordinate) of the applied pulse. In a y-detection period, a pulse generation circuit applies one pulse to a common line. The pen detects a potential variation in amplitude proportional to a distance (y-coordinate) from the source drive circuit, generated approximately simultaneously on all the signal wiring lines via a capacitance. The coordinate detection circuit obtains the y-coordinate similarly to the case of x-coordinate detection.
    • 准确检测输入位置。 在非显示周期的x检测周期中,源驱动电路同时向所有信号布线施加与从栅极驱动电路的距离成比例的峰值的脉冲。 坐标检测电路基于与所施加的脉冲的峰值(x坐标)对应的笔感应的电压来获得x坐标。 在y检测周期中,脉冲发生电路将一个脉冲施加到公共线。 笔检测到与来自源驱动电路的距离(y坐标)成比例的振幅的电位变化,其通过电容在所有信号布线上大致同时地产生。 坐标检测电路与x坐标检测的情况类似地获得y坐标。

    • A display device is arranged in such a manner that rows on the screen on which pixel electrodes are provided in a matrix manner are sequentially selected so as to be scanned by scanning signal lines formed on a substrate, and a data signal is supplied from gray scale signal lines, which are formed on a counter substrate facing the substrate, to the pixel electrodes on the selected row, so that the display is carried out. Also, an idle period, (i) which is longer than a scanning period for scanning the screen once and (ii) during which period all scanning signal lines are in the state of non-scanning, is provided, and the scanning period and the idle period constitute one vertical period. With this arrangement, it is possible to (1) provide a driving method of a display device by which method the reduction of power consumption is sufficiently realized without causing the degradation of the display qualities, and (2) provide a display device using the same.

    • A display apparatus includes a liquid crystal display panel, a front side viscoelastic layer, a front side hard layer, a back side viscoelastic layer, a back side hard layer, a backlight unit, a driving circuit board, and a metal plate. The front side viscoelastic layer that is viscoelastic covers a display surface of the liquid crystal display panel. The front side hard layer has a higher modulus of elasticity than the front side viscoelastic layer. The back side viscoelastic layer that is viscoelastic covers a back surface of the liquid crystal display panel. The back side hard layer has a higher modulus of elasticity than the back side viscoelastic layer. The back side viscoelastic layer has a thickness Tb of not less than about 20 μm, and the front side viscoelastic layer has a thickness Ta and satisfies: Ta/Tb>1 (Tb≠0). Thus, the display apparatus is resistant to breakage caused by a load placed on a display surface of the liquid crystal display panel and an impact when dropped, thereby attaining mechanical durability.
