BACKGROUND
1. Field

One or more aspects of example embodiments of the present invention relate to a display apparatus. More particularly, one or more aspects of example embodiments of the present invention relate to a display apparatus that may be operated in an inversion driving scheme.

2. Description of the Related Art

A liquid crystal display forms an electric field in a liquid crystal layer disposed between two substrates, and changes an alignment of liquid crystal molecules of the liquid crystal layer to control a transmittance of light incident to the liquid crystal layer. Thus, a desired image is displayed through the liquid crystal display.

Methods of driving the liquid crystal display include a line inversion method, a column inversion method, and a dot inversion method according to a phase of a data voltage applied to the data line. The line inversion method inverts the phase of image data applied to data lines for every pixel row. The column inversion method inverts the phase of the image applied to the data lines for every pixel column. The dot inversion method inverts the phase of the image data applied to the data lines for every pixel row and every pixel column.

In general, a display apparatus may display colors by using three primary colors of red, green, and blue colors. Accordingly, the display apparatus includes sub-pixels respectively corresponding to the red, green, and blue colors. In recent years, a display apparatus that displays the colors using red, green, blue, and a primary color has been suggested. The primary color may be one or two or more of magenta, cyan, yellow, and/or white. In addition, a display apparatus including red, green, blue, and white sub-pixels has been developed to improve brightness of the image. Red, green, and blue image signals are applied to the display panel after being converted to red, green, blue, and white data signals.

The above information disclosed in this Background section is for enhancement of understanding of the background of the present invention, and therefore, it may contain information that does not constitute prior art.

FIG. 1 is a block diagram showing a liquid crystal display 1000 according to an exemplary embodiment of the present invention, and FIG. 2 is an equivalent circuit diagram of one pixel shown in FIG. 1.

Referring to FIGS. 1 and 2, the liquid crystal display 1000 includes a liquid crystal panel 100, a timing controller 200, a gate driver 300, and a data driver 400.

The liquid crystal panel 100 includes a lower substrate 110, an upper substrate 120 facing the lower substrate 110, and a liquid crystal layer 130 between the lower substrate 110 and the upper substrate 120.

The liquid crystal panel 100 includes a plurality of gate lines G1 to Gm extending in a first direction DR1, and a plurality of data lines D1 to Dn extending in a second direction DR2 crossing the first direction DR1. The gate lines G1 to Gm and the data lines D1 to Dn define pixel areas, and pixels are arranged in the pixel areas, respectively. FIG. 1 shows a pixel PX connected to a first gate line G1 and a first data line D1.

The pixel PX includes a thin film transistor TR, a liquid crystal capacitor Clc, and a storage capacitor Cst. The thin film transistor TR is connected to one of the gate lines G1 to Gm and one of the data lines D1 to Dn. The liquid crystal capacitor Clc is connected to the thin film transistor TR. The storage capacitor Cst is connected to the liquid crystal capacitor Clc in parallel. The storage capacitor Cst may be omitted.

The thin film transistor TR is arranged on (e.g., under) the lower substrate 110. The thin film transistor TR may be a three-terminal device including a control terminal, a first terminal, and a second terminal. The control terminal of the thin film transistor TR is connected to a corresponding gate line (e.g., the first gate line G1), the first terminal of the thin film transistor TR is connected to a corresponding data line (e.g., the first data line D1), and the second terminal of the thin film transistor TR is connected to the liquid crystal capacitor Clc and the storage capacitor Cst.

The liquid crystal capacitor Clc includes a pixel electrode PE arranged on the lower substrate 110, and a common electrode CE arranged on the upper substrate 120 as its two terminals, and the liquid crystal layer 130 arranged between the pixel electrode PE and the common electrode CE serves as a dielectric substance. The pixel electrode PE is connected to the thin film transistor TR, and the common electrode CE is arranged on an entire surface of the upper substrate 120 to receive a common voltage. However, the present invention is not limited thereto, and according to another exemplary embodiment, the common electrode CE may be arranged on the lower substrate 110, and in this case, at least one of the pixel electrode PE and the common electrode CE may include slits.

The storage capacitor Cst assists the liquid crystal capacitor Clc and includes the pixel electrode PE, a storage line, and an insulating layer between the pixel electrode PE and the storage line. The storage line is arranged on the lower substrate 110 to overlap with a portion of the pixel electrode PE. The storage line receives a constant voltage (e.g., a storage voltage).

The pixel PX displays one of primary colors. The primary colors include red, green, blue, and white colors, but are not limited thereto or thereby. For example, the primary colors may further include various colors, e.g., cyan, magenta, yellow, etc. In the present exemplary embodiment, the pixel PX includes red, green, blue, and white pixels.

The pixel PX may further include a color filter CF corresponding to one of the primary colors. In FIG. 2, the color filter CF is arranged on the upper substrate 120, but the present invention is not limited thereto or thereby. For example, according to another exemplary embodiment, the color filter CF may be arranged on the lower substrate 110.

The timing controller 200 receives image data RGB and control signals from an external graphic controller. The control signals may include a vertical synchronization signal as a frame distinction signal Vsync, a horizontal synchronization signal as a row distinction signal Hsync, a data enable signal DE maintained or substantially maintained at a high level during a period when data is output to indicate a data input period, and a main clock signal MCLK.

The timing controller 200 converts the image data RGB according to specifications of the data driver 400. The timing controller 200 applies the converted image data DATA to the data driver 400. The timing controller 200 generates a gate control signal GS1 and a data control signal DS1. The gate control signal GS1 is applied to the gate driver 300, and the data control signal DS1 is applied to the data driver 400.

The gate control signal GS1 is used to drive the gate driver 300, and the data control signal DS1 is used to drive the data driver 400.

The gate driver 300 generates gate signals in response to the gate control signal GS1, and applies the gate signals to the gate lines G1 to Gm. The gate control signal GS1 may include a scan start signal for indicating a start of scanning, at least one clock signal for controlling an output period of a gate on voltage, and an output enable signal for controlling the maintaining of the gate on voltage.

The data driver 400 generates grayscale (e.g., gray level) voltages corresponding to the image data DATA in response to the data control signal DS1, and applies the grayscale (e.g., gray level) voltages to the data lines D1 to Dn as data voltages. The data voltages include a positive (+) data voltage having a positive value with respect to the common voltage, and a negative (−) data voltage having a negative value with respect to the common voltage. The data control signal DS1 may include a horizontal start signal STH for indicating a start of transmitting of the image data DATA to the data driver 400, a load signal for indicating application of the data voltages to the data lines D1 to Dn, and an inversion signal for inverting a polarity of the data voltages with respect to the common voltage.

The polarity of the data voltages applied to the pixels PX is inverted after one frame period is finished and before a next frame period starts to prevent or protect the liquid crystals from burning and/or from deteriorating. For example, the data driver 400 inverts the polarity of the data voltages every frame period in response to the inversion signal. In addition, when an image corresponding to one frame is displayed through the liquid crystal panel 100, the data voltages having different polarities are output in a unit of at least one data line, and applied to the pixels to improve display quality.

The data driver 400 alternately outputs the positive (+) data voltage and the negative (−) data voltage every one data line.

Each of the timing controller 200, the gate driver 300, and the data driver 400 may be directly mounted on the liquid crystal panel 100, attached to the liquid crystal panel 100 in a tape carrier package after being mounted on a flexible printed circuit board, or mounted on a separate printed circuit board. In another example, at least one of the gate driver 300 and the data driver 400 may be integrated on the liquid crystal panel 100 together with the gate lines G1 to Gm, the data lines D1 to Dn, and the thin film transistor TR. Alternatively, the timing controller 200, the gate driver 300, and the data driver 400 may be integrated in a single chip.

FIG. 3 is a plan view showing a portion of the liquid crystal panel 100 according to an exemplary embodiment of the present invention.

In FIG. 3, the red, green, blue, and white pixels are indicated by “R”, “G”, “B”, and “W”, respectively. The pixels applied with the data voltages having the positive (+) polarity are represented by “R+”, “G+”, “B+”, and “W+”, respectively, and the pixels applied with the data voltages having the negative (−) polarity are represented by “R−”, “G−”, “B−”, and “W−”, respectively.

Hereinafter, a position of each pixel may be referred to by a row and a column. For example, the red pixel connected to the first gate line G1 and the first data line D1 is arranged at a first row and a first column.

The row index increases from top to bottom in the figures, and the column index increases from left to right in the figures.

The polarities of the data voltages applied to the pixels of the liquid crystal panel 100 shown in FIG. 3 indicate polarities of the data voltages in an i-th frame period. The polarities of the data voltages are inverted in an (i+1)th frame period. That is, the data driver 400 shown in FIG. 1 inverts the polarities of the data voltages applied to the data lines D1 to Dn at every frame period. For example, the data voltages having the positive polarity and the data voltages having the negative polarity are alternately applied to the data lines D1 to D9.

The liquid crystal panel 100 includes a red pixel diagonal group RDG, a green pixel diagonal group GDG, a blue pixel diagonal group BDG, and a white pixel diagonal group WDG.

The red pixel diagonal group RDG includes the red pixels located at positions satisfying the condition that a number of columns increases by 2 when a number of rows increases by 1. As shown in FIG. 3, the red pixel diagonal group RDG includes the red pixel arranged at the position of the first row and the first column, the red pixel arranged at the position of the second row and the third column, the red pixel arranged at the position of the third row and the fifth column, and the red pixel arranged at the position of the fourth row and the seventh column.

The red pixels included in a same red pixel diagonal group RDG are applied with the data voltages having the same polarity. For example, the red pixel arranged at the position of the first row and the first column, the red pixel arranged at the position of the second row and the third column, the red pixel arranged at the position of the third row and the fifth column, and the red pixel arranged at the position of the fourth row and the seventh column shown in FIG. 3 are applied with the positive (+) data voltages.

The green pixel diagonal group GDG includes the green pixels located at positions satisfying the condition that the number of columns increases by 2 when the number of rows increases by 1. As shown in FIG. 3, the green pixel diagonal group GDG includes the green pixel arranged at the position of the first row and the second column, the green pixel arranged at the position of the second row and the fourth column, the green pixel arranged at the position of the third row and the sixth column, and the green pixel arranged at the position of the fourth row and the eighth column.

The green pixels included in a same green pixel diagonal group GDG are applied with the data voltages having the same polarity. For example, the green pixel arranged at the position of the first row and the second column, the green pixel arranged at the position of the second row and the fourth column, the green pixel arranged at the position of the third row and the sixth column, and the green pixel arranged at the position of the fourth row and the eighth column shown in FIG. 3 are applied with the negative (−) data voltages.

The blue pixel diagonal group BDG includes the blue pixels located at positions satisfying the condition that the number of columns decreases by 2 when the number of rows increases by 1. As shown in FIG. 3, the blue pixel diagonal group BDG includes the blue pixel arranged at the position of the first row and the seventh column, the blue pixel arranged at the position of the second row and the fifth column, the blue pixel arranged at the position of the third row and the third column, and the blue pixel arranged at the position of the fourth row and the first column.

The blue pixels included in a same blue pixel diagonal group BDG are applied with the data voltages having the same polarity. For example, the blue pixel arranged at the position of the first row and the seventh column, the blue pixel arranged at the position of the second row and the fifth column, the blue pixel arranged at the position of the third row and the third column, and the blue pixel arranged at the position of the fourth row and the first column shown in FIG. 3 are applied with the negative (−) data voltages.

The white pixel diagonal group WDG includes the white pixels located at positions satisfying the condition that the number of columns decreases by 2 when the number of rows increases by 1. As shown in FIG. 3, the white pixel diagonal group WDG includes the white pixel arranged at the position of the first row and the eighth column, the white pixel arranged at the position of the second row and the sixth column, the white pixel arranged at the position of the third row and the fourth column, and the white pixel arranged at the position of the fourth row and the second column.

The white pixels included in a same white pixel diagonal group WDG are applied with the data voltages having the same polarity. For example, the white pixel arranged at the position of the first row and the eighth column, the white pixel arranged at the position of the second row and the sixth column, the white pixel arranged at the position of the third row and the fourth column, and the white pixel arranged at the position of the fourth row and the second column shown in FIG. 3 are applied with the positive (+) data voltages.

Each of the red pixel diagonal group RDG, the green pixel diagonal group GDG, the blue pixel diagonal group BDG, and the white pixel diagonal group WDG is provided in a plurality of respective diagonal groups. The red pixel diagonal groups RDG adjacent to each other are applied with the data voltages having opposite polarities. For example, the red pixel diagonal group RDG including the red pixel (R+) arranged at the position of the first row and the first column, the red pixel (R+) arranged at the position of the second row and the third column, the red pixel (R+) arranged at the position of the third row and the fifth column, and the red pixel (R+) arranged at the position of the fourth row and the seventh column receives the data voltages having the positive (+) polarity, while the red pixel diagonal group including the red pixel (R−) arranged at the position of the first row and the fifth column and the red pixel (R−) arranged at the position of the second row and the seventh column receives the data voltages having the negative (−) polarity.

Similarly, the blue pixel diagonal groups BDG adjacent to each other receive the data voltages having opposite polarities, the green pixel diagonal groups GDG adjacent to each other receive the data voltages having opposite polarities, and the white pixel diagonal groups WDG adjacent to each other receive the data voltages having opposite polarities.

The red pixels of the red pixel diagonal group RDG are arranged in a direction different from a direction in which the blue pixels of the blue pixel diagonal group BDG are arranged. For example, the red pixels of the red pixel diagonal group RDG are arranged in a third direction DR3, while the blue pixels of the blue pixel diagonal group BDG are arranged in a fourth direction DR4. The third direction DR3 crosses the fourth direction DR4, and crosses the first and second directions DR1 and DR2.

The green pixels of the green pixel diagonal group GDG are arranged in a direction different from a direction in which the white pixels of the white pixel diagonal group WDG are arranged. For example, the green pixels of the green pixel diagonal group GDG are arranged in the third direction DR3, while the white pixels of the white pixel diagonal group WDG are arranged in the fourth direction DR4.

In general, human eyes may be more sensitive to certain colors than to other colors. For example, human eyes may be more sensitive to the white and green colors than to the red and blue colors. Thus, when pixels having a specific color are consecutively arranged in one direction, a stripe pattern image may be observed.

Since the red pixels of the same red pixel diagonal group RDG receive the data voltages having the same polarity, the stripe pattern image may be observed, and since the blue pixels of the same blue pixel diagonal group BDG receive the data voltages having the same polarity, the stripe pattern image may be observed. According to one or more of the exemplary embodiments of the present invention, the direction in which the red pixels of the red pixel diagonal group RDG are arranged is different from the direction in which the blue pixels of the blue pixel diagonal group BDG are arranged, and thus, a red stripe pattern may be offset against a blue stripe pattern. That is, when the liquid crystal panel 100 displays the red and blue colors together with each other, the red and blue stripe patterns may be prevented or substantially prevented from being observed in the diagonal directions.

Similarly, since the green pixels of the same green pixel diagonal group GDG receive the data voltages having the same polarity, the stripe pattern image may be observed, and since the white pixels of the same white pixel diagonal group WDG receive the data voltages having the same polarity, the stripe pattern image may be observed. According to one or more of the exemplary embodiments of the present invention, the direction in which the green pixels of the green pixel diagonal group GDG are arranged is different from the direction in which the white pixels of the white pixel diagonal group WDG are arranged, and thus, a green stripe pattern may be offset against a white stripe pattern. That is, when the liquid crystal panel 100 displays the green and white colors together with each other, the green and white stripe patterns may be prevented or substantially prevented from being observed in the diagonal directions.

The pixels adjacent to each other in the first direction DR1 and having the same color receive the data voltages having different polarities. In other words, the pixels having the same color that are adjacent to each other in the first direction DR1, such that three pixels are arranged therebetween, receive the data voltages having different polarities. For example, the red pixel (R+) arranged at the first row and first column receives the positive (+) data voltage, and the red pixel (R−) arranged at the first row and fifth column receives the negative (−) data voltage.

The polarity of the data voltages respectively applied to the pixels arranged in the same row is inverted in the unit of four pixels. For example, in the liquid crystal panel 100 shown in FIG. 3, the polarities of the data voltages applied to earlier four pixels (e.g., pixels arranged in the first to fourth columns) from among the pixels arranged in the h-th row ROW_h and the (h+1)th row ROW_h+1 are +, −, +, and −, respectively, and the polarities of the data voltages applied to later four pixels (e.g., pixels arranged in the fifth to eighth columns) following the earlier four pixels from among the pixels arranged in the h-th row ROW_h and the (h+1)th row ROW_h+1 are −, +, −, and +, respectively. In addition, the polarities of the data voltages applied to earlier four pixels (e.g., pixels arranged in the first to fourth columns) from among the pixels arranged in the (h+2)th row ROW_h+2 and the (h+3)th row ROW_h+3 are −, +, −, and +, respectively, and the polarities of the data voltages applied to later four pixels (e.g., pixels arranged in the fifth to eighth columns) following the earlier four pixels from among the pixels arranged in the (h+2)th row ROW_h+2 and the (h+3)th row ROW_h+3 are +, −, +, and −, respectively.

According to the present exemplary embodiment, the polarities of the data voltages applied to the pixels may be changed in various ways in accordance with the arrangements of the first to fourth red-green pixel groups RG1 to RG4 and the first to fourth blue-white pixel groups BW1 to BW4, without changing the arrangement of the polarities of the data voltages applied to the data lines.

In the liquid crystal panel 106 shown in FIG. 9, the polarities of the data voltages applied to earlier four pixels (e.g., pixels arranged in the first to fourth rows) from among the pixels arranged in each of the h-th column COL_h and the (h+3)th column COL_h+3 are +, +, −, and −, respectively, and the polarities of the data voltages applied to later four pixels (e.g., pixels arranged in the fifth to eighth rows) following the earlier four pixels from among the pixels arranged in the h-th column COL_h and the (h+3)th column COL _h+3 are −, −, +, and +, respectively. In addition, the polarities of the data voltages applied to earlier four pixels (e.g., pixels arranged in the first to fourth rows) from among the pixels arranged in each of the (h+1)th column COL_h+1 and the (h+2)th column COL_h+2 are −, −, +, and +, respectively, and the polarities of the data voltages applied to later four pixels (e.g., pixels arranged in the fifth to eighth rows) following the earlier four pixels from among the pixels arranged in the (h+1)th column COL_h+1 and the (h+2)th column COL₁₃h+2 are +, +, −, and −, respectively.
