摘要： A display device having a touch panel function includes a plurality of pixel circuits arranged in a matrix shape and sensing circuits arranged in a region between the adjacent pixel circuits for reading out a magnitude of coupling capacitance. A display driver writes a display signal in the pixel circuit every row line by driving the scanning lines and signal lines in a display operation period. A sensing driver senses a signal showing magnitude of the coupling capacitance from the sensing circuit every row line by driving the plurality of scanning lines and signal lines in a sensing operation period. The display operation period and the sensing operation period are repeated in turns. A voltage in a range used for the displaying operation is written into the signal line in a preliminary writing operation period between after the sensing operation period and before the display operation period.

摘要： When the horizontal period is less than a lower limit threshold value in a state that an LCD panel is driven in an SVGA mode, a mode judging circuit judges the resolution of an image signal as VGA. When the horizontal period is above an upper limit threshold value in a state that the LCD panel is driven in a VGA mode, the mode judging circuit judges the resolution of the image signal as SVGA. Even when frequency modulation is applied to the input signal, the modulation is absorbed by the width between the lower limit threshold value and the upper limit threshold value, whereby the resolution of the image signal can be reliably judged. A control signal generating circuit controls the timing of driving the LCD panel in accordance with the resolution, whereby image signals of a plurality of different resolutions can be reliably displayed on the LCD panel.
摘要翻译：当在SVGA模式下驱动LCD面板的状态下，当水平周期小于下限阈值时，模式判断电路将图像信号的分辨率判定为VGA。在LCD面板以VGA模式驱动的状态下，当水平周期高于上限阈值时，模式判断电路将图像信号的分辨率判断为SVGA。即使当对输入信号进行频率调制时，调制也被下限阈值和上限阈值之间的宽度吸收，从而可以可靠地判断图像信号的分辨率。控制信号发生电路根据分辨率控制驱动LCD面板的定时，从而可以在LCD面板上可靠地显示多个不同分辨率的图像信号。

摘要： A multi-gray level display designed to display multi-gray level images free of flicker or the like, by using a small number of voltages. The display comprises a first gray-level pattern generating circuit 311 for generating a first gray-level pattern which acquires a gray level during m frame periods, a second gray-level pattern generating circuit 321 for generating a second gray-level pattern which acquires another gray level during n frame periods (n is a positive integer greater than m), and a selection circuit 341 for selecting and outputting one of the preset voltages, in accordance with an output from the first gray-level pattern generating circuit 311 or the second gray-level pattern generating circuit 321 when the input multi-gray level display data corresponds to a gray level of either the first gray-level pattern or the second gray-level pattern.

摘要： Provided is a display device including a timing controller configured to generate a pulse of a start pulse signal (STH) once in every two frames. This configuration makes it possible to drive a source driver and a gate driver once in every two frames, and thereby to reduce power consumption. Moreover, when switching from a normal mode to a power saving mode, a personal computer only needs to turn on a power save control signal. Accordingly, it is possible to switch a liquid crystal display device into the power saving mode without causing distortion of a display screen.
摘要翻译：提供了一种显示装置，包括定时控制器，其被配置为在每两帧中产生一次起始脉冲信号（STH）的脉冲。这种配置使得可以在每两帧驱动源驱动器和栅极驱动器一次，从而降低功耗。此外，当从正常模式切换到省电模式时，个人计算机仅需要打开节电控制信号。因此，可以将液晶显示装置切换到省电模式，而不会导致显示屏的失真。

摘要： In the liquid crystal display device, in case a value prepared for setting brightness to a pixel is “001110”(L14), 8 bits obtained by the bit-shifting to lower direction by 2 bits(2 bit-shifting) and the setting of the bit value “1” is “11001110”. Frame rate control is thereafter performed by using upper 6 bits “110011” and 6 bits “110010” obtained when 1 is reduced from “110011”.
