The gate drivers 140 and 145 may be formed in the form of an IC (Integrated Circuit).

The data driver 150 samples and latches the data signal DATA in response to the data timing control signal DDC supplied from the timing controller 130, and converts the sampled data signal into a gamma reference voltage. The data driver 150 may invert the polarity of the data voltage at a specific frame period. The data driver 150 may invert the polarity of the data voltage in a frame inversion, a column inversion, a dot inversion, a Z inversion, or the like.

The data driver 150 supplies a data voltage (or a data signal) to the sub-pixels SP included in the liquid crystal panel 160 through the data lines DL. The data driver 150 is formed in the form of an IC (Integrated Circuit).

The liquid crystal panel 160 displays an image corresponding to the gate signal supplied from the gate drivers 140 and 145 and the data voltage supplied from the data driver 150.

Hereinafter, embodiments of the present invention will be described in addition to reviewing and solving the problems of the conventional liquid crystal display device.

BACKGROUND ART [0002]

FIG. 3 is a view for explaining a driving method of a conventional liquid crystal display device, and FIG. 4 is a view showing a problem of a conventional liquid crystal display device.

As shown in FIG. 3, the liquid crystal panel 160 is driven by a 4 dot inversion method in order to eliminate image quality issues that occur in a large or high resolution liquid crystal display device.

Conventionally, in order to drive the liquid crystal panel 160 in a 4-dot version mode, the data lines are arranged so that the left and right adjacent subpixels are connected to one channel. For example, the first channel CH1 provides a data voltage to the subpixels connected to the first data line DL1.

In addition, in the related art, gate lines are arranged such that two gate lines are paired and the upper and lower sub-pixels are alternately connected to each other. For example, the second and third gate lines GL2 and GL3 are arranged in pairs on the second scan line and provide gate signals to the upper and lower sub-pixels.

With respect to the above structure, when the liquid crystal panel 160 is driven by a 4-dot version system, a data voltage is supplied in a version form of Z on the liquid crystal panel 160. The subpixels are characterized by alternating positive and negative data voltages in the order of R + -> G + -> B + -> W + -> R- -> G- -> B- -> W- I repeat. In such a case, the polarity switching of the data voltage occurs every 4 horizontal times (4h time).

However, in the conventional liquid crystal display device, power consumption is increased and the problem of generation of heat of the data driver occurs even if the version is driven by 4 dots due to the increase of the size and the load of the liquid crystal panel 160. In addition, the conventional liquid crystal display device has a problem in that the reliability of the apparatus is deteriorated due to the driving failure caused by the heat of the data driver. In addition, in the conventional liquid crystal display device, due to the polarity accumulation (charging deviation-about charge area occurrence), the problem of image quality (also referred to as dribble defect) in which vertical stripes appear continuously on the liquid crystal panel 160 .

[Invention-First embodiment-]

FIG. 5 is a view schematically showing a part of a liquid crystal panel according to the first embodiment of the present invention, FIG. 6 is a view showing a part of the liquid crystal panel shown in FIG. 5, Fig. 8 is a diagram for explaining simulation results of the embodiment. Fig. Hereinafter, the horizontal line refers to the x direction and the vertical line refers to the y direction.

As shown in FIGS. 5 and 6, in order to solve the problems of the related art in the first embodiment, a switching transistor (TFT) of subpixels arranged in a diagonal direction (channel region asymmetry) The liquid crystal panel is constituted by the commonly connected subpixel groups PG. For example, the switching transistor (TFT) of the upper left (or upper right) subpixel and the switching transistor (TFT) of the lower right (or lower left) subpixel are connected to one data line.

The conditions for forming the subpixel group PG in the same manner as in the first embodiment and implementing the liquid crystal panel on the basis of the same will now be described.

The subpixel group PG includes a white subpixel W, a red subpixel R, a green subpixel G and a blue subpixel B arranged in two horizontal lines and four vertical lines, .

Specifically, subpixels are arranged in the order of a white subpixel W, a red subpixel R, a green subpixel G and a blue subpixel B in the Nth horizontal line. On the other hand, green subpixels G, blue subpixels B, white subpixels W, and red subpixels R are arranged in subpixels in the (N + 1) th horizontal line. However, the white subpixel W and the green subpixel G located on the left side of the first data line DL1 correspond to the dummy subpixel DSP. These are examples which may or may not have a switching transistor corresponding to a dummy sub-pixel (DSP). Accordingly, these connection relations refer to the white subpixel W and the green subpixel G arranged adjacent to the second data line DL2.

A white subpixel W, a red subpixel R, a green subpixel G, and a blue subpixel G are arranged in the same manner as the above-described subpixel group PG over two lines horizontally and vertically, The blue subpixel B is arranged. In other words, the (N + 2) th horizontal line has the same color arrangement structure as the (N + 1) th horizontal line and the (N + 3) th horizontal line has the same color arrangement structure as the (N + 1) th horizontal line.

The data lines have regions where the arrangement intervals of at least two (two regions) data lines are regularly different. The data lines have a portion spaced apart so that three subpixels are included between the two data lines and a portion spaced apart so that one subpixel is included between the two data lines.

Specifically, three subpixels are included between the first data line DL1 and the second data line DL2. On the other hand, one subpixel is included between the second data line DL2 and the third data line DL3. The reason why the disposition intervals of the data lines are different is to disperse the polarity of the data voltage up / down / left / right instead of being focused on a specific area. That is, if the arrangement interval is different, the polarity of the data voltage can be physically and structurally dispersed.

On the other hand, the switching transistor TFT of each subpixel is connected to the data line located on the left or right side through the first electrode (drain electrode). Therefore, the switching transistor (TFT) of each sub-pixel has a structure in which a first electrode is connected to a data line adjacent to itself, or a first electrode is connected to a data line located at a sub- .

The gate lines are arranged such that two gate lines are paired and connected alternately to the upper sub-pixel and the lower sub-pixel.

Specifically, the second and third gate lines GL2 and GL3 are arranged in pairs on the second horizontal line (the second and third scanning lines). The second gate line GL2 provides a gate signal to the upper sub-pixel G and the third gate line GL3 alternates up and down to provide a gate signal to the lower sub- And is connected to the gate electrode. However, in the first embodiment, the illustration of the dummy gate line is omitted. Thus, it should be understood that not only the first gate line GL1 but also the dummy gate line may be located in the first horizontal line.

In the liquid crystal panel implemented according to the first embodiment, the same polarity is applied twice consecutively and then the polarity is applied once (+, -, + +, - or -, +, - ), It is possible to solve the problem of the increase of the power consumption and the problem of the heating issue of the data driving part to some extent.

This is because the data lines are arranged in three lines and one line along the vertical direction, the gate lines are arranged in pairs in the horizontal direction, and the switching transistors (TFT) of the sub pixels are arranged in the vertical diagonal direction. In addition, the data voltage is supplied in a column-type version mode, but the polarity is charged in a dot-inversion form on the liquid crystal panel through the above structure.

However, in the first embodiment, as shown in FIG. 9, there is a possibility that a horizontal line defect may occur in a mixed color representation because polarity lumps (see yellow, cyan, and magenta square portions) exist in a specific region.

Hereinafter, the horizontal line refers to the x direction and the vertical line refers to the y direction.

As shown in FIGS. 8 and 9, in order to solve the problem of the conventional technique in the second embodiment, a switching transistor TFT of subpixels arranged in a diagonal direction (channel region asymmetry) The liquid crystal panel is constituted by the commonly connected subpixel groups PG. For example, the switching transistor (TFT) of the upper left (or upper right) subpixel and the switching transistor (TFT) of the lower right (or lower left) subpixel are connected to one data line.

The conditions for forming a subpixel group (PG) in the same manner as in the second embodiment and implementing the liquid crystal panel on the basis of the same will now be described.

(W), a red subpixel (R), a green subpixel (G), and a blue subpixel (G) in two horizontal lines and four vertical lines in the same manner as the above- The pixel B is arranged. However, subpixel groups are arranged in such a manner that the above structure is inverted over two lines in the next horizontal direction and four lines in the vertical direction.

For example, if the above-described subpixel group PG is a first subpixel group, then the second subpixel group is inverted as follows.

Specifically, green subpixels G, blue subpixels B, white subpixels W, and red subpixels R are arranged in subpixels in the (N + 2) th horizontal line. On the other hand, subpixels are arranged in order of the white subpixel W, the red subpixel R, the green subpixel G, and the blue subpixel B in the (N + 3) th horizontal line.

In other words, the (N + 2) th horizontal line has the same color arrangement structure as the (N + 1) th horizontal line and the (N + 3) th horizontal line has the same color arrangement structure as the Nth horizontal line. That is, unlike the first embodiment, the liquid crystal panel according to the second embodiment is implemented as a first subpixel group and a second subpixel group.

The data lines have regions where the arrangement intervals of at least three data lines are regularly different. The data lines have a portion spaced apart so that three subpixels are included between the two data lines and a portion spaced apart so that one subpixel is included between the two data lines.

Specifically, the second and third gate lines GL2 and GL3 are arranged in pairs on the second horizontal line (the second and third scanning lines). The second gate line GL2 provides a gate signal to the upper sub-pixel G and the third gate line GL3 alternates up and down to provide a gate signal to the lower sub- And is connected to the gate electrode. However, in the second embodiment, the illustration of the dummy gate line is omitted. Thus, it should be understood that not only the first gate line GL1 but also the dummy gate line may be located in the first horizontal line.

(+ +, -, + +, - or -, +, -, +) in which the same polarity is applied twice consecutively and then the other polarity is once applied to the liquid crystal panel implemented according to the second embodiment, ), It is possible to solve the problem of the increase of the power consumption and the problem of the heating issue of the data driving part to some extent.

However, in the second embodiment, subpixels (refer to the upper and lower subpixel portions of the fourth and fifth gate lines) representing the same color exist in the upper and lower portions, and the resolution is likely to decrease.

For example, the switching transistor (TFT) of the upper left (or upper right) subpixel of the first subgroup and the switching transistor (TFT) of the lower right (or lower left) subpixel are connected to one data line. And the switching transistor (TFT) of the upper left (or upper right) sub pixel and the switching transistor (TFT) of the lower left (or lower right) sub pixel of the second sub group are connected to one data line.

Specifically, in the (N + 2) th horizontal line, the white subpixel W, the red subpixel R, the green subpixel G, and the blue subpixel B are serially Pixels are arranged. In the (N + 3) th horizontal line, a green subpixel G, a blue subpixel B, a white subpixel W and a red subpixel R are provided in the same order as the (N + Pixel. In other words, the (N + 2) th horizontal line has the same color arrangement structure as the (N + 1) th horizontal line and the (N + 3) th horizontal line has the same color arrangement structure as the (N + 1) th horizontal line.

According to the above structure, the subpixels positioned on the liquid crystal panel have a form in which the first subgroup LRC and the second subgroup ULC alternate with respect to a pair of gate lines. In the first subgroup LRC, the portions forming the up-and-down diagonal direction from the left to the right and the portions forming the up-and-down diagonal direction from the right to the left are alternated.

On the other hand, the switching transistor TFT of each subpixel is connected to the data line located on the left or right side through the first electrode (drain electrode). Therefore, the switching transistor (TFT) of each subpixel has a first electrode connected to a data line adjacent to itself, or a first electrode connected to a data line located at a sub-pixel away from the first electrode, As shown in FIG.

The reason is that the data lines are arranged in three lines and one line along the vertical direction, the gate lines are arranged in pairs in the horizontal direction, and the switching transistors (TFT) of the sub pixels are arranged in the vertical diagonal direction and the vertical direction Because.

In addition, the data voltage is supplied in a column-type version mode, but the polarity is charged in a dot-inversion form on the liquid crystal panel through the above structure.

In FIG. 13, the actual drawing drawn in the liquid crystal panel 160 shows the order in which the charging is performed as the negative data voltage (-) is supplied. Referring to this charging sequence and the structure described above, the charging sequence of the positive polarity data voltage (+) will also be known.

On the other hand, in the third embodiment, the switching transistors (TFTs) of the subpixels are arranged in the up and down diagonal direction and the up and down direction, and the colors of the subpixels are arranged so as not to represent the same color. As a result, the third embodiment is able to eliminate (prevent) polarity clustering as in the first embodiment and the possibility of resolution degradation as in the second embodiment. That is, the third embodiment can be defined as an optimized structure so as to solve the problems that may occur in the first and second embodiments.

In addition, as can be seen from a comparison between the screen of FIG. 4 and the screen of FIG. 14, the third embodiment widens the interval at which the vertical stripes continuously appear on the liquid crystal panel 160, It can be said that the problem can be further alleviated (improved).
