[0011] The embodiments of this disclosure will be described below with reference to the drawings. This disclosure is not limited to the embodiments described below, and design modifications can be made as appropriate within the scope of satisfying the configuration of this disclosure. In the following description, the same reference numerals will be used in common across different drawings for the same parts or parts having similar functions, and repeated descriptions may be omitted. In addition, each configuration described in the embodiments may be combined or modified as appropriate without departing from the gist of this disclosure. In order to make the explanation easier to understand, the configurations in the drawings referenced below may be simplified or schematic, or some components may be omitted. Also, the dimensional ratios between components shown in each figure do not necessarily represent the actual dimensional ratios.

[0012] Figure 1 is a schematic cross-sectional view showing one configuration example of the liquid crystal display device 101 of this embodiment. The liquid crystal display device 101 comprises a liquid crystal panel 10 and a control device 50. The liquid crystal panel 10 includes a TFT substrate 20, a counter substrate 30, and a liquid crystal layer 40. As will be described later, the liquid crystal panel 10 includes a plurality of pixels arranged in the row and column directions. The liquid crystal layer 40 is located between the TFT substrate 20 and the counter substrate 30 and is sealed between the TFT substrate 20 and the counter substrate 30 by a seal 41.

[0013] The liquid crystal display device 101 may further include a pair of polarizing plates 42 and a backlight 80. The pair of polarizing plates 42 are arranged in a cross Nicol state with the liquid crystal panel 10 sandwiched therebetween.

[0014] The backlight 80 is arranged on the back surface 10b of the liquid crystal panel 10. The backlight 80 may be an edge type backlight or a direct - type backlight. Also, the backlight 80 may be capable of partial driving.

[0015] FIG. 2 is a schematic diagram showing a configuration example of the TFT substrate 20. The TFT substrate 20 includes a substrate 21, a plurality of source lines (data signal lines) SL, a plurality of gate lines (scanning signal lines) GL, and a plurality of pixels PX.

[0016] The substrate 21 has a main surface 21a including a display area 21h and a non - display area 21g which is an area other than the display area 21h. The plurality of gate lines GL, the plurality of source lines SL, and the plurality of pixels PX are arranged in the display area 21h. Specifically, the plurality of gate lines GL extend in the row direction (x - direction) and are arranged at a predetermined interval in the column direction (y - direction) intersecting the row direction. Also, the plurality of source lines SL extend in the column direction and are arranged at a predetermined interval in the row direction. A pixel PX is arranged in an area surrounded by an adjacent pair of gate lines GL and an adjacent pair of source lines SL. The plurality of pixels PX are arranged two - dimensionally in the row direction and the column direction. The source lines SL and the gate lines GL are extended into the non - display area 21g.

[0017] FIG. 3 is a circuit diagram showing the pixel PX of the TFT substrate 20 of the present embodiment. Each pixel PX includes a pixel electrode PE, a switching element SW, and a common electrode CE. The switching element SW is, for example, a thin film transistor (TFT) which is a three-terminal element, and a gate line GL, a source line SL, and a pixel electrode PE are connected to the three terminals. For example, the switching element is a TFT provided with a gate electrode GE, a source electrode SE, and a drain electrode DE, the gate electrode GE is connected to the gate line GL, the source electrode SE is connected to the source line SL, and the drain electrode DE is connected to the pixel electrode PE and the auxiliary capacitor CS. Thus, each pixel PX is connected to one of a plurality of gate lines GL and one of a plurality of source lines via the switching element SW.

[0018] Each gate line GL is connected to the gate electrode G of the TFT of the pixels PX arranged in the row direction among the plurality of pixels PX. On the other hand, each source line SL is connected to the source electrode S of the TFT of the pixels PX arranged in the column direction among the plurality of pixels PX.

[0019] The pixel electrode PE is arranged to face the liquid crystal layer 40. The common electrode CE is, for example, a single plate or sheet-like body that is connected to each other between adjacent pixels PX and extends over the entire display area 21h, and is located between the pixel electrode and the substrate 21. An insulating layer is arranged between the common electrode CE and the pixel electrode PE. The common electrode CE is provided over the entire display area 21h, and by applying a voltage between the pixel electrode PE and the common electrode CE, an electric field is generated in the liquid crystal layer 40, and the liquid crystal panel 10 is driven in a horizontal electric field mode such as IPS (In Plane Switching) or FFE (Fringe Field Switching). Thereby, a liquid crystal panel 10 with a wide viewing angle can be realized.

[0020] Multiple pixels PX include multiple pixels of different colors arranged in the same order in the row direction. Multiple pixels of different colors include pixels of colors with relatively high visual sensitivity. As shown in Figure 4, in this embodiment, the multiple colors are red (R), green (G), and blue (B), and multiple pixels PX include multiple red pixels PXr, multiple green pixels PXg, and multiple blue pixels PXb. Of red, green, and blue, green is the color with relatively high visual sensitivity, while red and blue are the colors with relatively low visual sensitivity. The color and arrangement of the pixels are determined by a color filter placed on the opposing substrate 30 or the TFT substrate 20.

[0021] Multiple different colors are not limited to the three primary colors of red, green, and blue; they may also be four primary colors consisting of red, green, blue, and yellow, or other combinations such as red, green, blue, and white. When the multiple different colors are red, green, blue, and yellow, the color with relatively higher visual sensitivity is yellow or green. Similarly, when the multiple different colors are red, green, blue, and white, the color with relatively higher visual sensitivity is white or green. The visual sensitivity of multiple different colors can also vary depending on the optical properties of the color filter used.

[0022] Furthermore, there may be two or more colors with relatively high visual sensitivity. For example, if the number of different colors is red, green, blue, and yellow, the colors with relatively high visual sensitivity may be yellow and green. If the number of different colors is red, green, blue, and white, the colors with relatively high visual sensitivity may be white and green. In other words, there may be one or more colors with relatively high visual sensitivity. The number of colors selected as colors with relatively high visual sensitivity can be determined by considering the balance between the effect of suppressing the occurrence of vertical streaks and the effect of suppressing the increase in power consumption.

[0023] A color pixel PXc, capable of displaying achromatic or arbitrary colors, is composed of three pixels adjacent in the row direction: a red pixel R, a green pixel G, and a blue pixel B. The red pixel PXr, green pixel PXg, and blue pixel PXb are called subpixels, and the group of these three subpixels is sometimes referred to as a pixel.

[0024] In the column direction, pixels of the same color are arranged, forming the columns Colr (red pixels), Colg (green pixels), and Colb (blue pixels). The column Colg (green pixels) is a column of pixels of a color that has relatively high visual sensitivity among several different colors. Each pixel in a column is connected to one of the source lines.

[0025] Figure 5 is a block diagram showing an example configuration of the control device 50. The control device 50 includes a timing controller 51, a gate drive circuit 52, and a source drive circuit 53. The control device 50 is composed of electronic circuits using active components such as ICs, LSIs, and FETs, and passive components such as resistors and capacitors.

[0026] The timing controller 51 receives a video signal from an external source. The video signal includes a video data signal and a video synchronization signal. Based on the received video signal, the timing controller 51 generates a gate control signal and a source control signal.

[0027] Gate control signals include, for example, a gate start pulse signal, a gate clock signal, and a gate clear signal. Source control signals include, for example, an image signal and a polarity control signal.

[0028] The gate drive circuit 52 and the source drive circuit 53 are located in a non-display area 21g of the substrate 21, as shown in Figure 2. The gate drive circuit 52 is connected to at least one end of the gate line GL. The source drive circuit 53 is connected to one end of the source line SL. The timing controller 51 is connected, for example, by a flexible printed circuit board (FPC) 90.

[0029] The gate drive circuit 52 and source drive circuit 53 may be components in a package covered with resin or the like, or bare chips, and may be mounted in the non-display area 21g of the substrate 21. Alternatively, the gate drive circuit 52 and source drive circuit 53 may be a monolithic driver composed of multiple TFTs or the like fabricated in the non-display area 21g of the substrate 21.

[0030] In this embodiment, the gate drive circuit 52 is located at both ends of the gate line GL and, like the TFT which is the switching element SW of the pixel PX, is a monolithic driver integrally formed with the substrate 21 by a TFT or the like formed on the substrate 21. On the other hand, in this embodiment, the source drive circuit 53 includes a plurality of source driver chips 53a. The source driver chips 53a are bare chips and are mounted on the substrate 21.

[0031] The gate drive circuit 52 receives the gate control signal, generates multiple scanning signals, and outputs them to multiple gate lines GL. The source drive circuit 53 receives the source control signal and outputs multiple data signals to the source line SL. The multiple data signals contain voltage values ​​corresponding to the grayscale display of each pixel. These voltage values ​​are positive (+) or negative (-) with respect to the reference potential (the potential applied to the common electrode), with a polarity determined by the polarity control signal.

[0032] Next, the control method for the liquid crystal display device 101 will be described. Figure 6 shows an example of the polarity of the data signal applied to each pixel when the liquid crystal panel 10 is driven by an AC drive in this embodiment. As described above, the "+" and "-" symbols indicate that the voltage applied to that pixel is positive or negative with respect to the reference potential. When a data signal is applied, the pixel electrode PE of each pixel is also maintained at a positive or negative potential with respect to the reference potential.

[0033] The timing controller 51 drives the rows of pixels of the color with relatively high visual sensitivity using a dot inversion drive method, and drives the rows of pixels of colors other than the color with relatively high visual sensitivity using a column inversion drive method. The dot inversion drive method referred to here means inversion driving one or more rows at a time, such as one row at a time or two rows at a time. If there are two colors with relatively high visual sensitivity, the rows of pixels of those two colors are driven using the dot inversion drive method, and the rows of pixels of the other colors are driven using the column inversion drive method. In this embodiment, the timing controller 51 drives the row of green pixels Colg using a row-by-row dot inversion drive method (1H dot inversion drive), and drives the row of red pixels Colr and the row of blue pixels Colb using the column inversion drive method. Since each pixel of the row of green pixels Colg is connected to one source line SL, the polarity of the data signal is inverted at the timing when the gate drive circuit 52 outputs a scan signal to each gate line GL. Therefore, in the column direction, the polarity of the green pixels PXg is alternately inverted.

[0034] On the other hand, in the red pixel column Colr and the blue pixel column Colb, the same polarity data signal is applied to all pixels in the column direction. In the row direction, adjacent red pixel columns Colr and blue pixel columns Colb are applied data signals with opposite polarities. Upon application of the data signal, the pixel electrode PE of each pixel PX becomes a potential with the same polarity as the data signal relative to the reference potential, and this is maintained for the duration of one frame.

[0035] Figure 7 shows the polarity of the data signal applied to each pixel in the frame following the frame in which the liquid crystal panel 10 was driven by a data signal supplied with the polarity shown in Figure 6. As shown in Figure 7, the polarity of the data signal applied to each pixel is reversed in the next frame.

[0036] Driving a liquid crystal panel using a column-reverse drive method has the advantage of achieving low power consumption. However, when the entire screen is displayed in intermediate colors (gray), even a slight deviation of the common electrode's potential from the optimal value will result in a brightness difference between pixels to which a positive data signal is applied and pixels to which a negative data signal is applied. For example, if the common electrode's potential deviates slightly to the positive side from the optimal value, the potential difference between the pixel electrode and the reference electrode will be smaller than the set value for pixels to which a positive data signal is applied, and larger than the set value for pixels to which a negative data signal is applied. As a result, for example, the brightness of the red pixel column and the blue pixel column will decrease, while the brightness of the green pixel column will increase. Consequently, vertical streaks along the column direction will appear in the display of intermediate colors, which should be uniform.

[0037] In the liquid crystal display device of this embodiment, some pixels are driven by a dot inversion driving method, and the remaining pixels are driven by a column inversion driving method. As a result, the occurrence of such vertical streaks is suppressed in pixels driven by the dot inversion driving method. In particular, since the green pixels, which have high visual sensitivity, are driven by the dot inversion driving method, the vertical streaks become less noticeable due to the visual characteristics.

[0038] On the other hand, driving using the dot inversion driving method consumes more power than driving using the column inversion driving method. In the liquid crystal display device of this embodiment, the increase in power consumption can be suppressed by limiting the number of pixels driven by the dot inversion driving method to only a portion of the pixels.

[0039] Therefore, according to the liquid crystal display device and control method of this embodiment, high display quality can be achieved with low power consumption.

[0040] (Second Embodiment) Figure 8 shows the polarity of the data signals applied to each pixel when the liquid crystal panel 10 is driven by an AC drive in this embodiment. In the first embodiment, the polarity of the green pixels is reversed for each pixel in the column direction. In this embodiment, the columns of green pixels are driven by a two-row dot inversion drive (2H dot inversion drive) method. The columns of red pixels and blue pixels are driven by a column inversion drive method, similar to the first embodiment.

[0041] With this type of drive, the polarity of the source line connected to the row of green pixels is reversed every time two gate lines are scanned. By making the reversal period longer than in the first embodiment, power consumption can be reduced even with the dot reversal drive method compared to the first embodiment.

[0042] Figure 9 shows the polarity of the data signal applied to each pixel when the column of green pixels is driven using a dot inversion drive method every four rows (4H dot inversion drive). The column of green pixels is driven using a dot inversion drive method every four rows, while the columns of red pixels and blue pixels are driven using a column inversion drive method similar to that of the first embodiment. Compared to dot inversion every two rows, the period for reversing the polarity of the source line can be made longer, thus further reducing power consumption.

[0043] However, if pixels of the same polarity continue for a long period in a row of green pixels, vertical streaks become more visible. The appearance of vertical streaks varies depending on the size and resolution of the liquid crystal panel 10 and the usage of the liquid crystal display device, so the number of rows of dot inversion in the row of green pixels should be determined according to these factors.

[0044] (Third embodiment) Figure 10 is a circuit diagram showing pixels PX on the TFT substrate 20 of the liquid crystal display device of this embodiment. Similar to the first embodiment, each row of red pixels and each row of blue pixels are connected to one source line SL. In contrast, each row of green pixels is connected to two source lines SL. More specifically, multiple green pixels arranged in the column direction are alternately connected to two source lines SL.

[0045] As shown in Figure 10, if the two source lines are designated as source line SL1 and source line SL2, then in the row of green pixels, odd-numbered pixels are connected to source line SL1, and even-numbered pixels are connected to source line SL2. Figure 11 shows the polarity of the data signals applied to each pixel when the liquid crystal panel 10 is driven by an AC drive method in this embodiment.

[0046] Similar to the first embodiment, the rows of red pixels and the rows of blue pixels are driven using a row inversion drive method. The row of green pixels is driven using a dot inversion drive method, and the multiple green pixels arranged in the row direction alternately have their polarity reversed.

[0047] The row of green pixels is driven by source lines SL1 and SL2. Source lines SL1 and SL2 output data signals to the green pixels with opposite polarities for the duration of one frame. The polarities of source lines SL1 and SL2 remain constant and do not change (reverse) during the duration of one frame. In other words, similar to the column inversion drive scheme, the polarities of source lines SL1 and SL2 do not change during the duration of one frame.

[0048] In the example shown in Figure 11, source line SL1 supplies a negative polarity data signal to the row of green pixels, and source line SL2 supplies a positive polarity data signal to the row of green pixels. When the gate line GL is scanned in the column direction, each TFT of the green pixels turns ON, and the negative polarity data signal supplied from source line SL1 and the positive polarity data signal supplied from source line SL2 are sequentially supplied to the green pixels. As a result, the polarity of the data signals in the row of green pixels is alternately reversed, and the row of green pixels is driven using a row-by-row dot inversion driving method.

[0049] According to the liquid crystal display device of this embodiment, as with the first embodiment, the occurrence of vertical streaks is suppressed when the entire screen is displayed in intermediate colors. Furthermore, since each row of green pixels is driven by two source lines, there is no need to invert the polarity of the data signal at the timing of gate line scanning during one frame period. As a result, power consumption can be reduced even further than that of the liquid crystal display device of the first embodiment.

[0050] The liquid crystal display device and the control method for the liquid crystal display device described herein can also be described as follows.

[0052] According to the first configuration, since one or more rows of pixels of relatively high visibility are driven by a dot inversion driving method, the visibility of vertical streaks is suppressed even when displaying an image using a single intermediate color. Furthermore, since only some pixels are driven by the dot inversion driving method, an increase in the overall power consumption of the liquid crystal display is suppressed.
