BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display panel, and more particularly, to a liquid crystal display panel and a driving device thereof capable of improving character display capability.                         

Conventional liquid crystal display devices display an image by adjusting the light transmittance of the liquid crystal using an electric field. To this end, the liquid crystal display includes a liquid crystal panel in which liquid crystal cells are arranged in a matrix and a driving circuit for driving the liquid crystal panel.

In fact, the liquid crystal display includes a liquid crystal panel 2 in which liquid crystal cells are arranged in a matrix as shown in FIG. 1, and a gate driver 4 for driving gate lines GL0 to GLn of the liquid crystal panel 2. ), A data driver 6 for driving the data lines DL1 to DLm of the liquid crystal panel 2, a gamma voltage generator 8 for supplying a gamma voltage to the data driver 6, and a gate. A timing controller 10 for controlling the driver 4 and the data driver 6 is provided.

The timing controller 10 controls the driving timing of the gate driver 4 and the data driver 6 in response to a clock signal, horizontal and vertical synchronization signals, etc. input from the outside. In other words, the timing controller 10 generates and supplies a gate shift clock GSC, a gate start pulse GSP, and the like to the gate driver 4 in response to the clock signal and the horizontal and vertical synchronization signals. In addition, the timing controller 10 generates a data clock signal, a data control signal, a polarity control signal, and the like in response to the input clock signal and the horizontal and vertical synchronization signals, and supplies the same to the data clock signal. The red (R), green (G), and blue (B) video data input from the outside are supplied to the data driver 6.

The gate driver 4 supplies the gate high voltage to the gate lines GL1 to GLn during the corresponding syringe period (1H) in response to the control of the timing controller 10 to drive the thin film transistors TFT. In the period, the gate low voltage is applied. In addition, the gate driver 4 applies a gate low voltage to the uppermost gate line GL0 formed for the storage capacitor Cst of the first scan line.

The data driver 6 converts a digital data signal from the timing controller 10 into an analog data signal in response to the control of the timing controller 10 to supply a gate high voltage to the gate lines GL1 to GLn for one horizontal period. The data signal for one horizontal line is supplied to the data lines DL1 to DLm every (1H). At this time, the gamma voltage generator 8 supplies the data driver 6 with a gamma voltage which is set in advance to have a different level according to the voltage level of the data signal. The data driver 6 converts the digital data signal into an analog data signal using the gamma voltage so that the gamma characteristic of the liquid crystal display device is corrected. In addition, the data driver 6 inverts the polarity of the data signals supplied to the data lines DL1 to DLm according to the polarity control signal from the timing controller 10.

The liquid crystal panel 2 is a thin film transistor TFT formed at intersections of liquid crystal cells arranged in a matrix form and n + 1 gate lines GL0 to GLn and m data lines DL1 to DLm. It is provided. The thin film transistor TFT supplies a data signal from the data lines DL1 to DLm to the liquid crystal cell in response to the gate high voltages from the gate lines GL1 to GLn. The liquid crystal cell may be equivalently represented as a liquid crystal capacitor Clc including a common electrode facing each other with a liquid crystal interposed therebetween and a pixel electrode connected to the thin film transistor TFT. A storage capacitor Cst is further formed in the liquid crystal cell to maintain the data voltage charged in the liquid crystal capacitor Clc until the next data voltage is charged, that is, while the gate low voltage is applied. The storage capacitor Cst is formed between the previous gate line and the pixel electrode.

In the liquid crystal panel 2, the thin film transistor array substrate that determines the shape of the liquid crystal cell is illustrated in FIG. 2.

Referring to FIG. 2, a pixel electrode 22 is provided in a cell region having a cross structure of gate lines GL0, GL1,..., And data lines DL1, DL2,. The pixel electrode 22 is connected to any one of the data lines DL1, DL2,... Through the source and drain electrodes 18, 20 of the thin film transistor 12. The gate electrode 16 of the thin film transistor 12 is connected to any one of the gate lines GL1, GL2,... The storage capacitor 14 is formed at an overlapping portion of the pixel electrode 22 and the previous gate line GLi-1. Each of the data lines DL1, DL2, ... is supplied with red, green, and blue data signals for color display.

Red, green, and blue color filters are formed to correspond to the cell region in which the pixel electrode 22 is formed, and the reference voltage is supplied to the thin film transistor array substrate and the upper substrate, which faces the liquid crystal layer. The common electrode is formed in front. Each of the liquid crystal cells in which the red, green, and blue color filters are formed corresponds to the subpixels (R, G, and B), and is a combination of the red, green, and blue subpixels (R, G, and B) arranged side by side. The pixel is represented.                         

In the conventional liquid crystal display device having such a configuration, the number of pixels is increasing as the resolution is increased to display a clear image. This increase in the number of pixels has led to an increase in the number of drive ICs (Integrated Circuits) for driving them, particularly expensive data drive ICs, thereby increasing the manufacturing cost. In addition, the liquid crystal display panel of the conventional stripe structure is easy to express a straight line, but the ability to express diagonal lines is poor. For example, as shown in Fig. 3, the ability to express "A" with diagonal lines is poor.

4 and 5, the pentile matrix structure shown in FIG. 2 can realize equivalent resolution even with a much smaller number of pixels than the existing matrix structure in which subpixels are arranged in a stripe shape. However, the pentile matrix structure illustrated in FIG. 5 has a problem in that oblique expression is easier than the existing matrix structure illustrated in FIG. Accordingly, recently, there is a demand for a liquid crystal display panel capable of smoother fonts.

In addition, in the liquid crystal display panel of the pentile matrix shown in FIGS. 4 and 5, since one pixel includes five subpixels, data must be supplied to the subpixels in a different data driving manner. In particular, the pentile matrix driving method requires that R and G subpixels share a single data line in order to reduce the number of expensive data drive ICs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 6 to 10E.

6 is a plan view illustrating a liquid crystal display panel having a hetile structure according to the first embodiment of the present invention. Each pixel P included in the hetile structure includes two G subpixels G1 and G2 facing in a diagonal direction, two B subpixels B1 and B2 facing in a different diagonal direction, and B It consists of two R subpixels R1 and R2 positioned between the subpixels B1 and B2 and the G subpixels G1 and G2. Thus, as each pixel is composed of six subpixels R1, G1, B1, R2, G2, and B2, the hetile structure uses fewer pixels than the conventional pentile matrix of which each pixel is composed of five subpixels. The same resolution can be achieved.

Each of the subpixels R1, G1, B1, R2, G2, and B2 is provided with six thin film transistors 30 connected to the gate line GL and the data line DL as switching elements. The thin film transistor 30 may include a gate electrode and data lines DL11, DL12, DL13, DL21, DL22, DL23 ... connected to any one of the gate lines GL11, GL12, GL21, GL22. And a drain electrode connected to the source electrode when the semiconductor layer (not shown) is activated by the gate high voltage applied to the gate electrode. The pixel electrode provided in the subpixel area is connected to the drain electrode. On the thin film transistor 30 and the thin film transistor substrate on which the pixel electrode is formed and the upper substrate (not shown) facing each other with the liquid crystal layer interposed therebetween, the red, green, and blue color filters correspond to the sub pixel region where the pixel electrode is formed. In addition, a common electrode for supplying a reference voltage to the liquid crystal layer is formed on the entire surface. Accordingly, each of the subpixels R1, G1, B1, R2, G2, and B2 is driven according to the data voltage supplied to the pixel electrode to emit light of a corresponding color, thereby displaying an image.

In FIG. 6, six subpixels R1, G1, B1, R2, G2, and B2 included in one pixel are driven by two gate lines GLi1 and GLi2. For example, the first R subpixel R1, the first G subpixel G1, and the first B subpixel B1 positioned at the top of the subpixels are the odd gate lines GL11, GL21, GL31,. The second R subpixel R2, the second G subpixel G2, and the second B subpixel B2 positioned at a lower end thereof are driven in a period where the gate high voltage is supplied to the gate high voltage. GL12, GL22, GL32, ...) are driven in the period in which the gate high voltage is supplied.

The odd gate line GLi1 and the even gate line GLi2 are formed by bending a predetermined angle at a predetermined period. For example, the odd gate line GLi1 is bent at a predetermined angle between the first R subpixel R1, the first B subpixel B1, and the first G subpixel G1 formed in a rhombus shape. The even gate line GLi2 is bent at a predetermined angle between the second R subpixel R2, the second B subpixel B2, and the first G subpixel G1 formed in a rhombus shape.

In addition, the subpixels R1, G1, B1, R2, G2, and B2 included in one pixel receive a data signal through three data lines DLk1, DLk2, and DLk3. For example, the first B subpixel B1 and the second G subpixel G2 are connected to the k1th data line DLk1, and the first G subpixel G1 and the second B subpixel B2.

DLk2 alternately supplies the G data signal and the B data signal to the second B subpixel B2 and the first G subpixel G1 every one horizontal period.

The k1, k2, k3 data lines DLk1, DLk2, DLk3 are formed by bending at predetermined angles at predetermined periods. For example, the k1th data line DLk1 is bent at a predetermined angle between the second R subpixel R2, the first B subpixel B1, and the second G subpixel G2 of the previous pixel. The kth data line DLk2 is bent at a predetermined angle between the first R subpixel R1, the first B subpixel B, and the second G subpixel G2 of the previous pixel. The kth data line DLk3 is formed by bending at a predetermined angle between the second R subpixel R2, the second B subpixel B2, and the first G subpixel G1.

As described above, the liquid crystal display panel and the driving apparatus thereof having the hetile structure according to the first exemplary embodiment of the present invention have each pixel as six sub-pixels R1, G1, B1, R2, G2, and B2. The same resolution can be realized by using fewer pixels than a conventional pentile matrix composed of five sub-pixels. In addition, by driving six subpixels with a total of three data lines, the number of data lines can be reduced, and further, the number of data drive ICs can be reduced. In addition, since the data line and the gate line are formed by bending at a predetermined angle, the first to sixth sub-pixels formed in the pixel region of the data line and the gate line are formed in a polygonal shape with diagonal lines, so that not only the linear representation but also the diagonal representation ability is provided. Is improved.

It consists of R1 and R2. Here, the areas of the B subpixels B and the G subpixels G are similar to the areas of the two B subpixels B and the two G subpixels G shown in FIG. 6, respectively.

In this way, each pixel P is composed of a total of four subpixels R1, R2, G, and B. Since the area of each pixel is similar to that of each pixel shown in FIG. 6, each pixel includes five subpixels. It is possible to implement the same resolution using fewer pixels than the conventional pentile matrix.

Each of the subpixels R1, R2, G, and B is provided with four thin film transistors 30 connected to the gate line GL and the data line DL as switching elements.

And a drain electrode connected to the source electrode when the semiconductor layer (not shown) is activated by the gate high voltage applied to the gate electrode. The pixel electrode provided in the subpixel area is connected to the drain electrode. On the thin film transistor 30 and the thin film transistor substrate on which the pixel electrode is formed and the upper substrate (not shown) facing each other with the liquid crystal layer interposed therebetween, the red, green, and blue color filters correspond to the sub pixel region where the pixel electrode is formed. In addition, the common electrode for supplying a reference voltage to the liquid crystal layer is formed on the front surface. Accordingly, each of the subpixels R1, R2, G, and B is driven according to the data voltage supplied to the pixel electrode to emit light of a corresponding color, thereby displaying an image.                     

Meanwhile, as illustrated in FIG. 8, the G subpixel G and the B subpixel B shown in FIG. 7 are connected to the first and second pixel electrodes 70a, 70b, 80a, and 80b and the connection portions 70c, respectively. 80c). That is, the first and second pixel electrodes 70a, 70b, 80a, and 80b of the G subpixel G and the B subpixel B may have two gate lines GLi1, GLi2 and two data lines DLk1, The connection parts 70c and 80c are formed in the pixel area provided by the DLk2, and the connection parts 70c and 80c are formed in the intersection area of the G subpixel G and the B subpixel B that intersect in the area overlapping the gate line GLi2.

The connection portion 70c of the G subpixel is formed of a metal different from the gate lines GL and the pixel electrodes 70a and 70b, for example, of the same metal as the data line DL. The connection part 70c is connected to the first and second pixel electrodes 70a and 70b of the G subpixel through the first and second contact holes 84a and 84b.

The connection portion 80c of the B subpixel is formed of the same metal as the pixel electrodes 80a and 80b and is directly connected to the first and second pixel electrodes 80a and 80b of the B subpixel without contact holes.

In contrast, the connection portion 80c of the B subpixel is connected to the first and second pixel electrodes 80a and 80b through the contact hole, and the connection portion 70c of the G subpixel is connected to the first and second pixels without the contact hole. It may be connected to the electrodes 70a and 70b.

In FIG. 7, four subpixels R1, R2, G, and B included in one pixel are driven by two gate lines GL. For example, the first R subpixels R1 and B subpixels B of the subpixels are driven in a period when a gate high voltage is supplied to the odd gate lines GL11, GL21, GL31, ..., The second R subpixels R2 and G subpixels G are driven during a period when a gate high voltage is supplied to the even gate lines GL12, GL22, GL32, ....

In addition, the subpixels R1, R2, G, and B included in one pixel receive a data signal through two data lines DLk1 and DLk2. For example, the B subpixel B and the G subpixel G2 are connected to the k1th data line DLk1, and the first R subpixel R1 and the second R subpixel R2 are k2th data. It is connected to the line DLk2. Accordingly, the k-th data line DLk alternately supplies the B data signal and the G data signal to the B subpixel B and the G subpixel G every one horizontal period, and the kth data line DLk1 The R data signal is supplied to the first R subpixel R1 and the second R subpixel R2 every one horizontal period.

As described above, the liquid crystal display panel having the hetile structure and the driving apparatus thereof according to the second embodiment of the present invention have four subpixels R1, G, B, and R2 as each pixel includes four subpixels R1, G, B, and R2. Since the TFT is required, the light transmittance is improved over the pentile matrix structure required by the five TFTs. In addition, since two data lines are required to implement four sub-pixels, the number of data lines can be reduced, and the number of data drive ICs can be reduced by two-thirds compared to that of the stripe type structure. In addition, since the data line and the gate line are formed by bending at a predetermined angle, the first to fourth sub-pixels formed in the pixel region of the data line and the gate line are formed in a polygonal shape with diagonal lines, so that not only the linear representation but also the diagonal representation ability is provided.

And a control signal generator 44 for generating a data control signal DCS. The frame memory 40 stores and outputs pixel data RGB input from the outside in units of frames. The pixel data sorter 42 separates pixel data from the frame memory 40 into odd horizontal line data and even horizontal line data, and then sequentially outputs them. For example, the pixel data alignment unit 42 outputs pixel data of odd horizontal lines among pixel data of one frame, and then outputs pixel data of even horizontal lines.

The gate driver 48 drives the odd horizontal lines and the even horizontal lines of the liquid crystal display panel 52 separately. For example, the gate driver 48 sequentially supplies gate high voltage scan pulses to the odd gate lines GLi1 for one frame, and then sequentially scans gate high voltages to the even gate lines GLi2. Will be supplied. In this case, the gate driver 48 is generated every horizontal period in which a scan pulse is generated.

The data driver 50 converts pixel data of odd horizontal lines into an analog pixel signal when the odd gate lines GLi1 are driven, and supplies pixels of even horizontal lines when the even gate lines GLi2 are driven. The data is converted into an analog pixel signal and supplied. Accordingly, the odd horizontal lines are sequentially driven by the odd gate line GLi in each frame, and the even horizontal lines are sequentially driven by the even gate lines GLi2.

In detail, when the odd horizontal lines of the liquid crystal display panel illustrated in FIG. 6 are driven in the nth frame, the data driver 50 supplies the B data signal to the k1 th data line DLk1 and the k2 th data line. The G data signal is supplied to DLk2, and the R data signal is supplied to kth data line DLk3. Then, when the even horizontal lines are driven in the nth frame, the data driver 50 supplies a G data signal to the k1 th data line DLk1 and a B data signal to the k2 th data line DLk2. The R data signal is supplied to the k3 th data line DLk3.

In addition, when the odd horizontal lines of the liquid crystal display panel illustrated in FIG. 7 are driven in the nth frame, the data driver 50 supplies the B data signal to the k1 th data line DLk1 and the k2 th data line DLk2.

Next, when the even horizontal lines are driven in the nth frame, the data driver 50 supplies a G data signal to the k1 th data line DLk1 and an R data signal to the k2 th data line DLk2.

That is, any one of the R subpixel, the G subpixel, and the B subpixel is formed in a rhombus shape, and the remaining subpixels are formed in a hexagonal shape. In addition, in order to drive the liquid crystal display panel of the hetile structure according to the present invention, other devices besides the device proposed in FIG. 9 may drive the liquid crystal display panel of the hetile structure. In addition, although the sub-pixels of the liquid crystal display panel according to the present invention have been described to implement one of R (Red), G (Green), and B (Blue), other colors, for example, in addition to R, G, and B, , Y (Yellow), C (Cyan), M (Magenta), W (White) may be implemented.

As described above, the liquid crystal display panel and its driving apparatus according to the present invention each pixel is composed of six subpixels, or four subpixels having an area similar to the six subpixels. Accordingly, the same resolution can be realized by using fewer pixels than the conventional pentile matrix composed of five sub-pixels. In addition, the number of data lines can be reduced by driving up to six subpixels with up to three data lines, and further, the number of data drive ICs can be reduced. In addition, the data line and the gate line are formed by bending at a predetermined angle, so that up to six sub-pixels formed in the sub-pixel area of the data line and the gate line are arranged in an oblique or intersecting structure, so that not only a straight line expression but also a character of a curve and a handwriting I can express it.
