20100097366 | LIQUID CRYSTAL DISPLAY - In one embodiment of the present invention, each pixel includes first and second subpixels. CS bus lines connected to the respective storage capacitors of the first and second subpixels are electrically independent of each other. A CS voltage has a waveform that inverts its polarity at least once a frame, which includes a first subframe for sequentially scanning a series of odd rows and a second SF for sequentially scanning even rows that have been skipped during the first SF. A source signal voltage varies so as to have two frames or subframes with mutually opposite polarities. A CS voltage has a waveform that has quite opposite consequences on the effective voltage of a subpixel of a pixel connected to the j | 04-22-2010 |
20100097367 | LIQUID CRYSTAL DISPLAY DEVICE, SCAN SIGNAL DRIVE DEVICE, LIQUID CRYSTAL DISPLAY DEVICE DRIVE METHOD, SCAN SIGNAL DRIVE METHOD, AND TELEVISION RECEIVER - In one embodiment of the present invention, a liquid crystal display device is disclosed in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. The first period and the second period are defined as follows. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion. Thus, even when a data signal waveform is not sharp upon polarity inversion, it is possible to suppress display unevenness and perform a high-quality display. | 04-22-2010 |
20100103339 | LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal display device according to the present invention includes: a plurality of pixels that are arranged in rows and columns so as to form a matrix pattern; and TFTs (TFT-A, TFT-B and TFT-C), source bus lines, gate bus lines and CS bus lines (CS-A and CS-B), which are associated with the respective pixels. Each pixel includes at least three subpixels (SP-A, SP-B and SP-C) with liquid crystal capacitors that are able to retain mutually different voltages. By supplying a signal (CS-A or CS-B) that makes two of the at least three subpixels display mutually different luminances at least at a certain grayscale tone from the source, gate and CS bus lines to each pixel, the at least three subpixels are able to display mutually different luminances. | 04-29-2010 |

20100118013 | LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE DRIVE METHOD, AND TELEVISION RECEIVER - In one embodiment of the present invention, a gate driver creates a dummy insertion period in which the driver does not apply a gate on pulse to a scanning signal line immediately after the time of the inversion of a data signal. When a period from the time of the application of the gate on pulse to an odd numbered or even numbered scanning signal line to which the gate on pulse is applied previously to the time of the application of the gate on pulse to an even numbered or odd numbered scanning signal line to which the gate on pulse is applied later is set as an adjacent line writing time lag period for two scanning signal lines adjacent to each other, a CS control circuit allows the polarity of every CS signal to be reversed on the same cycle at least in the adjacent line writing time lag period. This makes it possible to provide a liquid crystal display device capable of offering high quality display in which unevenness in the display is suppressed without being affected by the blunt waveform of the data signal and the blunt waveform of a retention volume signal at the time of the inversion. | 05-13-2010 |
20100123832 | LIQUID CRYSTAL PANEL DRIVING APPARATUS, LIQUID CRYSTAL DISPLAY APPARATUS, METHOD FOR DRIVING LIQUID CRYSTAL DISPLAY APPARATUS, DRIVE CONDITION SETTING PROGRAM, AND TELEVISION RECEIVER - In one embodiment of the present invention, a liquid crystal panel driving apparatus is disclosed which sequentially receives pieces of video data for one data signal line, (i) prepares a data string by sorting, in order of outputting, a plurality of pieces of video data inputted in a predetermined period while adding a piece of dummy data to a predetermined position, (ii) assigns one horizontal scanning period to an output of a piece of video data while assigning a dummy scanning period to an output of a piece of dummy data, and (iii) sets one horizontal scanning period shorter than an interval of inputting of pieces of video data. This makes it possible to suppress an increase in vertical display period even though a piece of dummy data is added to inputted video data while a dummy scanning period is assigned thereto. | 05-20-2010 |

20100253668 | LIQUID CRYSTAL DISPLAY, LIQUID CRYSTAL DISPLAY DRIVING METHOD, AND TELEVISION RECEIVER - First and second data signal lines are provided for a column of pixels, and signal potentials of opposite polarity to each other are supplied to the data signal lines respectively. In at least one embodiment, a predetermined pixel is taken as the first pixel. A pixel other than the (2×n×i+1)-th pixel in the scanning direction is connected to a data signal line different from that connected to the previous pixel, whereas the (2×n×i+1)-th pixel is connected to the same data signal line as that connected to the previous pixel. The polarity of the signal potential supplied to each data signal line is inverted every n horizontal scanning periods. Every adjacent two scan signal lines starting from the scan signal line connected to the predetermined pixel are sequentially selected at the same time among scan signal lines. A liquid crystal display with this structure enables an increase of the pixel charging time as well as prevention of flickering. | 10-07-2010 |
