The present invention relates to, for example, an electro-optical device using an electro-optic material such as liquid crystal, a driving method of the electro-optical device, and an electronic device having the electro-optical device.

Background Art Conventionally, electro-optical devices such as liquid crystal devices for displaying images are known. This electro-optical device includes, for example, a first substrate having a backlight, a plurality of scan lines, a plurality of data lines, and a plurality of pixel electrodes and switching elements formed corresponding to the intersections of the scan lines and the data lines, and the first substrate. And a second substrate formed opposite to the second substrate, and a liquid crystal formed between the first substrate and the second substrate to control light from the backlight.

Here, the electro-optical device is formed with a display area composed of a plurality of pixels formed in correspondence with the plurality of pixel electrodes and the switching elements described above. In addition, the plurality of pixels includes a pixel having a red (R) color filter, a pixel having a green (G) color filter, and a pixel having a blue (B) color filter.

According to the electro-optical device described above, the liquid crystal shutter is controlled by supplying an image signal to the above three types of pixels. When light is emitted from the backlight, the light passes through the liquid crystal shutter controlled by the pixel and then is irradiated onto the entire surface of the display area. Light incident on each pixel of the display area is emitted through the color filter.

In recent years, however, improvement in color reproducibility of electro-optical devices has been demanded. Thus, the following method is known.

First, there is an electro-optical device in which one kind of color filter is added to four kinds of pixels (see Patent Document 1). According to this electro-optical device, since color gamut can be enlarged by four kinds of pixels, color reproducibility can be improved.

Secondly, there is a method of displaying an intermediate gray scale by determining the lighting time per frame of the pixel.

That is, first, a liquid crystal panel is constructed by including pixels capable of displaying two types of gray scales of the first gray scale and the second gray scale, and a plurality of these pixels are bundled to form one block, and then the pixels constituting the block are first Divided into groups and second group. Then, the pixel belonging to the first group is turned on with either the first or the second grayscale over the reference period, while the pixel belonging to the second group is flashed with either the first grayscale or the second grayscale (for example, , Patent Document 2).

According to the electro-optical device using the method for displaying the intermediate gray scale disclosed in Patent Document 2, not only the gray level of each pixel is changed, but also the number of basic display gray scales is controlled by controlling the lighting time of the pixels constituting the block. Since multi-gradation display is possible without increasing, color reproducibility can be improved.

In the display area A, a plurality of pixels 57 are arranged in a matrix, and the plurality of pixels 57 are pixels 57 having a color filter of red (R) and a color of green (G). The pixel 57 which has a filter, the pixel 57 which has the color filter of blue (B), and the pixel 57 which has the color filter of cyan (C) are provided.

As described above, the pixel 57 has four types of red (R), green (G), blue (B), and cyan (C). Therefore, the four types of pixels 57 arranged in the horizontal direction in FIG. 3 are used as one set, and the sets of the pixels 57 are arranged in four groups in total and four groups in total in the horizontal direction to the pixel block 52. do.

In the present embodiment, the four types of pixels 57 are stripe arrays as shown in FIG.

First, the FRC implemented in the display gradation control circuit 96 with respect to the pixel 57 of red (R) and the pixel 57 of blue (B) will be described.

FIG. 4: is a schematic diagram which shows the lighting pattern for every frame of 16 red (R) pixels 57 among the pixels 57 which comprise the pixel block 52. FIG.

In Fig. 4, the vertical axis is a gradation level expressed using the lower two bits of the eight-bit display data.

On the other hand, the horizontal axis is a frame number. This frame number returns to "0" when counting up from "0" to "3".

The pixel block 52 of FIG. 4 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. It is comprised including four red (R) pixels 57.

Then, the position in the pixel block 52 of these 16 red (R) pixels 57 is represented by (x, y) (x is a column number, y is a line number). The pixel block 52 displays one gray scale as a whole by selectively lighting the sixteen red (R) pixels 57.

In the pixel block 52, the pixel 57 of " 0 " is lit at grayscale K (where 0 ≦ K ≦ 62), and the pixel 57 of “1” is lit at grayscale K + 1.

For example, when the lower two bits of the display data are "00" and the frame number is "0", the sixteen red (R) pixels 57 of the pixel block 52 are turned on as follows.

That is, the red (R) pixels 57 of (0,0), (1,1), (2,3), and (3,2) are turned on at grayscale K + 1, and the remaining red (R) pixels (57) are turned on. ) Light up in gradation K.

When the frame is switched and the frame number is "1", the red (R) pixel 57 of (0,2), (1,3), (2,1), (3,0) lights up in grayscale K + 1. The remaining red (R) pixels 57 are turned on with a gray K.

When the frame is switched and the frame number is "2", the red (R) pixels 57 of (0,1), (1,0), (2,2), and (3,3) light up in grayscale K + 1. The remaining red (R) pixels 57 are turned on with a gray K.

When the frame is switched and the frame number is "3", the red (R) pixel 57 of (0,3), (1,2), (2,0), (3,1) lights up in grayscale K + 1. The remaining red (R) pixels 57 are turned on with a gray K.

When the frame is switched again, the frame number returns to "0", and the red (R) pixel 57 lights up as in the case where the lower two bits of the above-described display data are "00" and the frame number is "0". Let's do it.

As described above, when the lower two bits of the display data are "00", the pixel block 52 including the 16 red (R) pixels 57 has a gray level (K + 1) which is an intermediate gray level of the gray level K and the gray level K + 1. / 4) Red (R) is displayed.

Similarly, when the lower two bits of the display data are " 01 ", the pixel block 52 composed of the 16 red (R) pixels 57 has a red color of gray (K + 1/2), which is an intermediate gray between gray K and gray K + 1. (R) is displayed.

Similarly, when the lower two bits of the display data are "10", the pixel block 52 which consists of 16 red (R) pixels 57 is red of gradation (K + 3/4) which is an intermediate gradation of gradation K and gradation K + 1. (R) is displayed.

Similarly, when the lower two bits of the display data are "11", the pixel block 52 which consists of 16 red (R) pixels 57 displays the red (R) of gradation (K + 1).

As described above, the electro-optical device 1 performs FRC by switching the lighting pattern for lighting with the grayscale K and the grayscale K + 1 in each of the sixteen red (R) pixels 57 constituting the pixel block 52 for each frame. By doing so, the red (R) of the intermediate gradations of gradation K and gradation K + 1 is displayed.

FIG. 5: is a schematic diagram which shows the lighting pattern for every column of 16 red (R) pixels 57 among the pixels 57 which comprise the pixel block 52. FIG.

In FIG. 4, the sixteen red (R) pixels 57 are represented for each frame, whereas in FIG. 5, the sixteen red (R) pixels 57 are represented for each column.

That is, in FIG. 5, the horizontal axis is a column number and means four columns (columns) from 0th to 3rd.

The pixel block 52 of FIG. 5 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. Two red (R) pixels 57 are configured.

The positions of these sixteen red (R) pixels 57 in the pixel block 52 are then expressed by [x, y] (x is the number of the frame and y is the number of the line). The pixel block 52 selectively lights up the 16 red (R) pixels 57, thereby displaying one gray scale as a whole.

5 and 4 express the same lighting pattern for the sixteen red (R) pixels 57 although the expression methods are different as described above.

For example, in Fig. 5, when the lower two bits of the display data are " 00 " and the column number is " 0 ", the red (R) pixel 57 to be turned on in grayscale K + 1 is [0,0], [ 1,2], [2,1], [3,3]. These pixels 57 are (0,0) in the case where the lower two bits of the display data are "00" and the frame number is "0" in FIG. 4, and the lower two bits of the display data are "00" and the frame (0,2) when the number is "1", when the lower two bits of the display data are "00" and (0,1) when the frame number is "2", the lower two bits of the display data is "00" And frame number is " 3 "

FIG. 6: is a schematic diagram which shows the lighting pattern for every frame of 16 blue (B) pixel 57 among the pixels 57 which comprise the pixel block 52. FIG.

In Fig. 6, similarly to Fig. 4, the vertical axis is a gradation level expressed using the lower two bits of the 8-bit display data, and the horizontal axis is a frame number. This frame number is synchronized with the frame number of FIG.

The pixel block 52 of Fig. 6 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. And blue (B) pixels 57.

Then, the position in the pixel block 52 of these 16 blue (B) pixels 57 is represented by (x, y) (x is a column number, y is a line number). The pixel block 52 selectively lights up the 16 blue (B) pixels 57 to display one gray scale as a whole.

In the pixel block 52, the pixel 57 of " 0 " is lit at gray scale L (where 0 ≦ L ≦ 62), and the pixel 57 of “1” is gray scale L + 1 (where 0 ≦ L ≦ 62) on.

For example, when the lower two bits of the display data are "00" and the frame number is "0", the sixteen blue (B) pixels 57 of the pixel block 52 are turned on as follows.

That is, the blue (B) pixels 57 of (0,1), (1,0), (2,2), and (3,3) are turned on at grayscale L + 1, and the remaining blue (B) pixels (57). ) In the gray scale L.

When the frame is switched and the frame number is "1", the blue (B) pixel 57 of (0,3), (1,2), (2,0), (3,1) lights up in gray scale L + 1. The remaining blue (B) pixels 57 are turned on with the gray level L.

When the frame is switched and the frame number is "2", the blue (B) pixel 57 of (0,0), (1,1), (2,3), (3,2) lights up in gray scale L + 1. The remaining blue (B) pixels 57 are turned on with the gray level L.

When the frame is switched and the frame number is "3", the blue (B) pixel 57 of (0,2), (1,3), (2,1), (3,0) lights up in gray scale L + 1. The remaining blue (B) pixels 57 are turned on with the gray level L.

When the frame is switched again, the frame number returns to " 0 ", so that the pixel 57 of blue (B) is turned on as in the case where the lower two bits of the above-described display data are " 00 " and the frame number is " 0 ". Let's do it.

As described above, when the lower two bits of the display data are "00", the pixel block 52 including the 16 blue (B) pixels 57 has a gray level (L + 1) which is an intermediate gray level of the gray level L and the gray level L + 1. / 4) blue (B) is displayed.

Similarly, when the lower two bits of the display data are " 01 ", the pixel block 52 composed of the 16 blue (B) pixels 57 has a gray level (L + 1/2), which is an intermediate gray level between the gray level L and the gray level L + 1. Blue (B) is displayed.

Similarly, when the lower two bits of the display data are "10", the pixel block 52 which consists of 16 blue (B) pixels 57 has the gray level (L + 3/4) which is an intermediate gray level of gray L and gray L + 1. Blue (B) is displayed.

Similarly, when the lower two bits of the display data are "11", the pixel block 52 which consists of 16 blue (B) pixels 57 displays the blue (B) of gradation (L + 1).

In this manner, the electro-optical device 1 performs FRC by switching the lighting pattern for lighting with the grayscale L and the grayscale L + 1 in each of the frames of the 16 blue (B) pixels 57 constituting the pixel block 52. By doing so, blue (B) of the intermediate gray of the gray level L and the gray level L + 1 is displayed.

FIG. 7: is a schematic diagram which shows the lighting pattern for every column of 16 blue (B) pixel 57 among the pixels 57 which comprise the pixel block 52. FIG.

In FIG. 6, the sixteen blue (B) pixels 57 are represented for each frame, whereas in FIG. 7, the sixteen blue (B) pixels 57 are represented for each column.

That is, in FIG. 7, the horizontal axis is a column number and means four columns (columns) from 0th to 3rd.

The pixel block 52 of FIG. 7 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. Two blue (B) pixels 57.

Then, the position in the pixel block 52 of these 16 blue (B) pixels 57 is expressed by [x, y] (x is a frame number and y is a line number). The pixel block 52 selectively lights up the 16 blue (B) pixels 57 to display one gray scale as a whole.

7 and 6 express the same lighting pattern for the 16 blue (B) pixels 57 although the expression methods are different as described above.

For example, in Fig. 7, when the lower two bits of the display data are " 00 " and the column number is " 0 ", the pixel 57 of the blue (B) lighted with the gray scale L + 1 is [0,1], [1,3], [2,0], [3,2]. These pixels 57 have (0,1) in the case where the lower two bits of the display data are "00" and the frame number is "0" in FIG. (0,3) when the number is "1", (0,0) when the lower 2 bits of display data is "00" and the lower 2 bits of the display data is "00" when the frame number is "2" And frame number is " 3 ".

As described above, when the lower two bits of the display data are "00" and the frame number is "0", from FIG. 4, (0,0), (1,1) among the 16 red (R) pixels 57 ), (2,3), (3,2) are lighted with the gradation K + 1, and the remaining red (R) pixel 57 is lighted with the gradation K.

6, (0,1), (1,0), (2,2), and (3,3) of the 16 blue (B) pixels 57 are turned on at gray scale L + 1, and the remaining blue (B) The pixel 57 is turned on with the gray level L. FIG.

Subsequently, when the frame number is "2", from FIG. 4, (0,1), (1,0), (2,2), (3,3) of the 16 red (R) pixels 57 Is lighted at grayscale K + 1, and the remaining red (R) pixels 57 are lighted at grayscale K.

6, (0,0), (1,1), (2,3), and (3,2) of the sixteen blue (B) pixels 57 are turned on at gray scale L + 1, and the remaining blue (B) The pixel 57 is turned on with the gray level L. FIG.

Therefore, in the case where the frame number is "0" and "2", the red (R) pixel 57 and the blue (B) pixel 57 display the gray level interchangeably.

Accordingly, of the 16 red (R) pixels 57 (0,0), (1,1) of FIG. 4 and the 16 blue (B) pixels 57 of FIG. 6, (0,1), (1, 0) are adjacent to each other and are out of phase with each other on the spatial frequency. Further, (2,3), (3,2) of the 16 red (R) pixels 57 of FIG. 4 and (2,2), (3 of the 16 blue (B) pixels 57 of FIG. 6. And (3) are adjacent to each other and are out of phase with each other on the spatial frequency.

As described above, in the electro-optical device 1, the two types of pixels described above are different in phase with each other on the spatial frequency with respect to the sixteen red (R) pixels 57 and the sixteen blue (B) pixels 57. Carry out FRC with the lighting pattern specified.

Next, the FRC performed by the display gray scale control circuit 96 with respect to the green (G) pixel 57 and the cyan (C) pixel 57 will be described.

FIG. 8: is a schematic diagram which shows the lighting pattern for every frame of 16 green (G) pixel 57 among the pixels 57 which comprise the pixel block 52. FIG.

In FIG. 8, the vertical axis is a gradation level expressed using the lower two bits of the eight-bit display data.

On the other hand, the horizontal axis is a frame number. This frame number returns to "0" when counting up from "0" to "3".

The pixel block 52 of FIG. 8 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. Four green (G) pixels 57 are configured.

The position in the pixel block 52 of these sixteen green (G) pixels 57 is then expressed by (x, y) (x is the number of the column and y is the number of the line). The pixel block 52 selectively lights up the sixteen green (G) pixels 57 to thereby display one gray scale as a whole.

In the pixel block 52, the pixel 57 of " 0 " is lit by the gray scale M (where 0 ≦ M ≦ 62), and the pixel 57 of “1” is lit by the gray scale M + 1. .

For example, when the lower two bits of the display data are "10" and the frame number is "0", the sixteen green (G) pixels 57 of the pixel block 52 are turned on as follows.

That is, the green (G) pixels 57 of (0,3), (1,2), (2,0), and (3,1) are turned on in gray scale M, and the remaining green (G) pixels 57 ) Is turned on at gradation M + 1.

When the frame is switched and the frame number is "1", the green (G) pixel 57 of (0,0), (1,1), (2,3), (3,2) lights up in gradation M The remaining green (G) pixels 57 are turned on with a gray scale M + 1.

When the frame is switched and the frame number is "2", the green (G) pixel 57 of (0,2), (1,3), (2,1), (3,0) lights up in gradation M The remaining green (G) pixels 57 are turned on with a gray scale M + 1.

When the frame is switched and the frame number is "3", the green (G) pixel 57 of (0,1), (1,0), (2,2), (3,3) lights up in gray scale M The remaining green (G) pixels 57 are turned on with a gray scale M + 1.

When the frame is switched again, the frame number returns to "0", and the green (G) pixel 57 lights up as in the case where the lower two bits of the above-described display data are "10" and the frame number is "0". Let's do it.

As described above, when the lower two bits of the display data are "10", the pixel block 52 including the 16 green (G) pixels 57 has a gray level (M + 3) which is an intermediate gray level of the gray level M and the gray level M + 1. / 4) green (G).

Similarly, when the lower two bits of the display data are "00", the pixel block 52 composed of the sixteen green (G) pixels 57 has a gray level (M + 1/4) that is an intermediate gray level between the gray level M and the gray level M + 1. Green (G) is displayed.

Similarly, when the lower two bits of the display data are " 01 ", the pixel block 52 composed of the sixteen green (G) pixels 57 has a gray level (M + 1/2) that is an intermediate gray level between the gray level M and the gray level M + 1. Green (G) is displayed.

Similarly, when the lower two bits of the display data are "11", the pixel block 52 which consists of 16 green (G) pixels 57 displays the green G of gradation (M + 1).

In this manner, the electro-optical device 1 performs FRC by switching the lighting pattern for lighting with the gray scale M and the gray scale M + 1 in each of the sixteen green (G) pixels 57 constituting the pixel block 52 for each frame. By doing so, the green (G) of the intermediate gradations of the gradation M and the gradation M + 1 is displayed.

FIG. 9: is a schematic diagram which shows the lighting pattern for every column of 16 green (G) pixel 57 among the pixels 57 which comprise the pixel block 52. FIG.

In FIG. 8, the sixteen green (G) pixels 57 are represented for each frame, whereas in FIG. 9, the sixteen green (G) pixels 57 are represented for each column.

That is, in FIG. 9, the horizontal axis is a column number and means four columns (columns) from 0th to 3rd.

The pixel block 52 of FIG. 9 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. Four green (G) pixels 57, respectively.

The position in the pixel block 52 of these sixteen green (G) pixels 57 is then expressed by [x, y] (x is the number of the frame and y is the number of the line). The pixel block 52 selectively lights up the sixteen green (G) pixels 57 to thereby display one gray scale as a whole.

9 and 8 express the same lighting pattern for the sixteen green (G) pixels 57 although the expression methods are different as described above.

For example, in Fig. 9, when the lower two bits of the display data are " 10 " and the column number is " 0 ", the green (G) pixel 57 to be turned on in gray scale M is [0,3], [ 1,0], [2,2], [3,1]. These pixels 57 are (0,3) when the lower two bits of the display data are "10" and the frame number is "0" in FIG. 8, and the lower two bits of the display data are "10" and the frame (0,0) when the number is "1", when the lower two bits of display data are "10" and (0,2) when the frame number is "2", the lower two bits of display data is "10" And (0, 1) when the frame number is "3".

FIG. 10: is a schematic diagram which shows the lighting pattern for every frame of 16 cyan (C) pixel 57 among the pixels 57 which comprise the pixel block 52. FIG.

In Fig. 10, as in Fig. 8, the vertical axis is a gradation level expressed using the lower two bits of the 8-bit display data, and the horizontal axis is a frame number. This frame number is synchronized with the frame number of FIG.

The pixel block 52 of FIG. 10 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. And cyan pixels (57).

Then, the position in the pixel block 52 of these 16 cyan (C) pixels 57 is represented by (x, y) (x is a column number and y is a line number). The pixel block 52 selectively lights up sixteen cyan (C) pixels 57, thereby displaying one gray scale as a whole.

In the pixel block 52, the pixel 57 of " 0 " is lit at grayscale N (where 0 ≦ N ≦ 62), and the pixel 57 of " 1 " is lit at grayscale N + 1.

For example, when the lower two bits of the display data are "10" and the frame number is "0", the sixteen cyan (C) pixels 57 of the pixel block 52 are turned on as follows.

That is, the cyan (C) pixels 57 of (0,2), (1,3), (2,1), and (3,0) are turned on with grayscale N, and the remaining cyan (C) pixels are lit. (57) is lighted with gradation N + 1.

When the frame is switched and the frame number is "1", the cyan (C) pixel 57 of (0,1), (1,0), (2,2), (3,3) is converted to grayscale N. The remaining cyan (C) pixels 57 are turned on with a gray level N + 1.

When the frame is switched and the frame number is "2", the cyan (C) pixel 57 of (0,3), (1,2), (2,0), (3,1) is converted to grayscale N. The remaining cyan (C) pixels 57 are turned on with a gray level N + 1.

When the frame is switched and the frame number is "3", the cyan (C) pixel 57 of (0,0), (1,1), (2,3), (3,2) is converted to grayscale N. The remaining cyan (C) pixels 57 are turned on with a gray level N + 1.

When the frame is switched again, the frame number returns to " 0 ", and the cyan (C) pixel 57 is replaced with the case where the lower two bits of the above-described display data are " 10 " and the frame number is " 0 ". Lights up.

As described above, when the lower two bits of the display data are "10", the pixel block 52 including the sixteen cyan (C) pixels 57 has a gray scale which is an intermediate gray scale of the gray scale N and the gray scale N + 1. N + 3/4) cyan (C) is displayed.

Similarly, when the lower two bits of the display data are "00", the pixel block 52 composed of the sixteen cyan (C) pixels 57 has a gray level (N + 1/4) which is an intermediate gray level of the gray level N and the gray level N + 1. Cyan (C) is displayed.

Similarly, when the lower two bits of the display data are "01", the pixel block 52 which consists of 16 cyan (C) pixels 57 has a gray level (N + 1/2) which is an intermediate gray level of the gray level N and the gray level N + 1. Cyan (C) is displayed.

Similarly, when the lower two bits of the display data are "11", the pixel block 52 which consists of 16 cyan (C) pixels 57 displays cyan (C) of gradation (N + 1).

In this way, the electro-optical device 1 switches the lighting pattern for turning on the gray level N and the gray level N + 1 in each of the 16 cyan (C) pixels 57 constituting the pixel block 52 for each frame to select FRC. By doing so, cyan (C) of the intermediate gradations of gradation N and gradation N + 1 is displayed.

FIG. 11: is a schematic diagram which shows the lighting pattern for every column of 16 cyan (C) pixel 57 among the pixels 57 which comprise the pixel block 52. FIG.

In FIG. 10, 16 cyan (C) pixels 57 are represented for each frame, whereas in FIG. 11, 16 cyan (C) pixels 57 are represented for each column.

That is, in FIG. 11, the horizontal axis is a column number and means four columns (columns) from 0th to 3rd.

The pixel block 52 of FIG. 11 is a 4x4 16 represented by four lines (rows) from No. 0 to No. 3 and four columns (columns) from No. 0 to No. 3. And cyan (C) pixels 57.

The positions of these sixteen cyan (C) pixels 57 in the pixel block 52 are then expressed by [x, y] (x is a frame number and y is a line number). The pixel block 52 selectively lights up sixteen cyan (C) pixels 57, thereby displaying one gray scale as a whole.

11 and 10 express the same lighting pattern for the sixteen cyan (C) pixels 57 although the expression methods are different as described above.

For example, in Fig. 11, when the lower two bits of the display data are " 10 " and the column number is " 0 ", the cyan (C) pixel 57 to be turned on in grayscale N is [0,2], [1,1], [2,3], [3,0]. These pixels 57 are (0,2) in the case where the lower two bits of the display data are "10" and the frame number is "0" in FIG. 10, the lower two bits of the display data are "10" and the frame. (0,1) when the number is "1", when the lower two bits of display data are "10" and (0,3) when the frame number is "2", the lower two bits of display data is "10" And (0,0) when the frame number is "3".

As described above, when the lower two bits of the display data are "10" and the frame number is "0", from FIG. 8, (0,3), (1,2) of the 16 green (G) pixels 57 ), (2,0), (3,1) are lighted with gradation M, and the remaining green (G) pixels 57 are lighted with gradation M + 1.

10, (0,2), (1,3), (2,1), and (3,0) of the sixteen cyan (C) pixels 57 are turned on with gray scale N, and the remaining The cyan (C) pixel 57 is turned on with a gray level N + 1.

Subsequently, when the frame number is "2", from (8,2), (1,3), (2,1), (3,0) of the 16 green (G) pixels 57 from FIG. Is lighted at gradation M, and the remaining green (G) pixels 57 are lighted at gradation M + 1.

10, (0,3), (1,2), (2,0), and (3,1) of the sixteen cyan (C) pixels 57 are turned on with gray scale N, and the remaining The cyan (C) pixel 57 is turned on with a gray level N + 1.

Therefore, in the case where the frame number is "0" and "2", the green (G) pixel 57 and the cyan (C) pixel 57 display the gray level interchangeably.

Thus, (0,3), (1,2) of the 16 green (G) pixels 57 of FIG. 8 and (0,2), (of the 16 cyan (C) pixels 57 of FIG. 1 and 3 are adjacent to each other and are out of phase with each other on the spatial frequency. Further, (2,0), (3,1) of the 16 green (G) pixels 57 of FIG. 8 and (2,1), (of the 16 cyan (C) pixels 57 of FIG. 3,0) are adjacent to each other and are out of phase with each other on the spatial frequency.

As described above, in the electro-optical device 1, the two kinds of pixels described above are inversely phased with each other on the spatial frequency with respect to the sixteen green (G) pixels 57 and the sixteen cyan (C) pixels 57. FRC is performed with the lighting pattern set to be.

According to this embodiment, there exist the following effects.

(1) In the electro-optical device 1, a pixel 57 having a color filter of red (R) and a pixel 57 having a color filter of blue (B) and a pixel 57 having a color filter of green (G) ( A plurality of pixels 57 are formed, including the pixel 57 having a color filter of 57 and cyan (C), and for each frame constituting the reference frame, each pixel 57 has a first gray level or a second gray level. Display in gradation. Therefore, when viewed from the reference frame, the intermediate gradations between the first gradation and the second gradation can be displayed, and the color reproducibility can be improved.

(2) A plurality of data lines transmit image signals such that adjacent ones of pixels 57 having a color filter of red (R) and pixels 57 of a color filter of blue (B) are in phase out of each other on a spatial frequency. It supplies to 20 each. Further, the image signals are sent to the plurality of data lines so that the adjacent ones of the pixels 57 having the green (G) color filter and the pixels 57 having the cyan (C) color filter are opposite to each other on the spatial frequency. It supplies to 20 each. Therefore, the pixel 57 having the color filter of red (R) and the pixel 57 having the color filter of blue (B), the pixel 57 having the color filter of green (G) and cyan (C) The pixels 57 having color filters can be canceled with each other, so that generation of flicker and color deviation can be suppressed.

<Variation example>

In addition, this invention is not limited to the said embodiment, A deformation | transformation, improvement, etc. in the range which can achieve the objective of this invention are included in this invention.

For example, the four types of pixels 57 constituting the pixel block 52 are not limited to the lighting pattern shown in the present embodiment, and are red (R) and blue (B), green (G), and cyan. What is necessary is just to light it by the pattern which can cancel each color of (C).

In addition, in this embodiment, the some pixel 57 is the pixel 57 which has the color filter of red (R), the pixel 57 which has the color filter of green (G), and the color filter of blue (B). Although the pixel 57 which has and the pixel 57 which has the color filter of cyan (C) was provided, it is not limited to this.

For example, red (R) and blue (B), green (G), and cyan (C) described above, respectively, the colored region (R) of the red-based color and the colored region (B) of the blue-based color described below ) And colored regions G and C of two kinds of colors selected from the colors blue to yellow.

The four color regions are selected from two colors selected from the blue color region, the red color region, and the blue to yellow color in the visible light region (380 to 780 nm) whose color changes depending on the wavelength. It consists of a colored area of. What is used here as a system is not limited to pure blue color as long as it is a blue system, for example, contains blue purple, cyan, etc. If it is a red system color, it is not limited to red but includes orange. In addition, these colored areas may be comprised by a single colored layer, and may be comprised overlapping the colored layer of several different color.

The other colored region selected from the colors blue to yellow is green to orange, and more preferably green to yellow. Or green to yellowish green.

Here, each colored region does not use the same color. For example, when the green color is used in two colored areas selected from the colors blue to yellow, the other uses a blue or yellowish green color for one green color.

This makes it possible to realize a wider color reproducibility than the conventional RGB colored region.

Although a wide range of color reproducibility has been described in color, as another specific example, it is expressed by the wavelength which transmits a colored region below.

Next, it expresses with the x, y chromaticity diagram as another specific example.

The blue colored region is a colored region at x ≦ 0.151, y ≦ 0.200, preferably a colored region at x ≦ 0.151, y ≦ 0.056, and more preferably 0.134 ≦ x ≦ 0.151, 0.034 ≦ y ≦ It is a colored area at 0.200. More preferably, it is a colored area | region in 0.134 <x <= 0.151 and 0.034 <= y <0.056.

The red-colored region is a colored region at 0.520 ≦ x, y ≦ 0.360, preferably a colored region at 0.643 ≦ x, y ≦ 0.333, more preferably 0.550 ≦ x ≦ 0.690, 0.210 ≦ y ≦ 0.360 It is the coloring area in. More preferably, it is a coloring area | region in 0.643 <= x <0.690 and 0.299 <y <0.333.

One colored region selected from the colors blue to yellow is a colored region in x ≦ 0.200, 0.210 ≦ y, preferably a colored region in x ≦ 0.164, 0.453 ≦ y, more preferably 0.080 ≦ It is a colored area | region in x <= 0.200 and 0.210 <= y <0.759. More preferably, it is a colored area | region in 0.098 <= x <0.164, 0.453 <= y <0.759.

The other colored region selected from the colors blue to yellow is a colored region at 0.257≤x and 0.450≤y, preferably a colored region at 0.257≤x and 0.606≤y, more preferably 0.257≤ It is a colored area | region in x <= 0.520 and 0.450 <= y <0.720. More preferably, it is a colored area | region in 0.257 <= x <= 0.357 and 0.606 <= y <0.670.

In addition, this x, y chromaticity diagram is a numerical value obtained by the illumination light from a lighting apparatus passing through a color filter in the case of a transmissive display, and a numerical value obtained by reflecting external light in the case of a reflective display. When the colored region of these four colors is provided with a transmissive region and a reflective region in the subpixel, the transmissive region and the reflective region can also be applied in the above-described ranges.
