Embodiment 1
[0049] FIG. 1 is a block diagram showing the electrical configuration of main parts of a liquid crystal display device according to a first embodiment of the present invention. The liquid crystal display device in this example, as shown in FIG. 1 , includes a timing controller 11 , a source driver 12 , a gate driver 13 , a liquid crystal display panel 14 , and a backlight 15 .
[0050] FIG. 2 is a schematic diagram showing an example of the electrical structure of the liquid crystal display panel 14 in FIG. 1 . This liquid crystal display panel 14 is a transmissive liquid crystal panel that makes the light of the backlight incident. As shown in FIG. ), multiple rows of scanning electrodes Yj (j=1, 2, . The data electrodes Xi are arranged at predetermined intervals in the x direction, and are applied with corresponding display data Di. The scan electrodes Yj are provided at predetermined intervals in the y direction perpendicular to the x direction, and are applied with a sca...
Embodiment 2
[0065] FIG. 11 is a timing chart illustrating the operation of the liquid crystal display device according to the second embodiment of the present invention. 12 is a diagram illustrating the voltage polarity inversion of data written in each pixel region of the second embodiment, FIG. 13 is a waveform diagram illustrating each part of the operation of each liquid crystal display device of the second embodiment, and FIG. 14 is A diagram of another example of voltage polarity inversion of write data written in the pixel region of the second embodiment. 15 is a diagram showing another example of voltage polarity inversion of write data written in a pixel region in the second embodiment. 16 is a diagram showing another example of voltage polarity inversion of write data written in the pixel region in the second embodiment. The processing contents of the driving method used in the liquid crystal display device in this example will be described with reference to the above-mentioned...
Embodiment 3
[0069] FIG. 17 is a timing chart illustrating the operation of the liquid crystal display device according to the third embodiment of the present invention. The above-mentioned embodiment 1 is driven at half the frequency of normal black insertion, but in embodiment 3, when the double-speed driving of the liquid crystal panel and each circuit is possible, 1 frame is divided into 4 fields, and the odd number When the switching frequency of the even-numbered field is set to a frequency more than twice the frame frequency, a liquid crystal display device, a drive control circuit and a driving method used in the liquid crystal display device can be provided, and the frequency multiplication caused by the high-speed frame frequency is related to the frequency multiplication of the liquid crystal display device. The frequency halving effect caused by the inventive drive cancels out, so the flickering frequency of black display and image display is doubled with the same operating freq...
