Please refer to FIG. 1 , which is a schematic diagram of a display panel 200 according to an embodiment of the invention. The display panel 200 includes a first row of pixels 210 and a second row of pixels 220. The first row of pixels 210 and the second row of pixels 220 respectively include a plurality of first color sub-pixels 310 and a plurality of sub-pixel combinations 230. Each sub-pixel combination 230 has a second color sub-pixel 320 and a third color sub-pixel 330 arranged in a first direction y. The plurality of first color sub-pixels 310 and the plurality of sub-pixel combinations 230 are staggered in a second direction x that is substantially perpendicular to the first direction y.

The corresponding two sides of the display panel 200 are composed of the first color sub-pixels 310. Therefore, in any row of pixels 210 or 220 of the first row of pixels 210 and the second row of pixels 220, the number of the first color sub-pixels 310 is one more than the number of the second color sub-pixels 320. And the number of the second color sub-pixels 320 and the number of the third color sub-pixels 330 are the same.

In addition, as shown in FIG. 1, the second color sub-pixel 320 of each sub-pixel combination 230 is connected to the center points A and B of the third color sub-pixel 330. a line substantially perpendicular to the center points C and D of the two first color sub-pixels 310 adjacent to the one-pixel combination 230 .

Although FIG. 1 only shows the first row of pixels 210 and the second row of pixels 220 of the display panel 200, the present invention is not limited thereto. The display panel 200 can include more rows of pixels, and both ends of each row of pixels are composed of the first color sub-pixels 310. In other words, in each row of pixels, the number of first color sub-pixels 310 is one more than the number of second color sub-pixels 320, and the second color sub-pixels 320 included in each row of pixels The number will be equal to the number of its third color sub-pixels 330. In addition, in other embodiments of the present invention, each row of pixels may include more first color sub-pixels 310 and sub-pixel combinations 230, as long as the first color sub-pixels 310 in each row of pixels The number is one more than the number of sub-pixel combinations 230.

Referring to FIG. 1 again, the first row of pixels 210 and the second row of pixels 220 may be two rows of adjacent pixels, and the first second color sub-pixel 320 of the first row of pixels 210. Optionally, adjacent to the first second color subpixel 320 of the second row of pixels 220, and the second third color subpixel 330 of the first row of pixels 210 is selectively operably The second third color sub-pixel 330 of the second row of pixels 220 is adjacent. In other words, the second color sub-pixel 320 and the third color sub-pixel 330 in the two sub-pixel combinations 230 on each side of each first color sub-pixel 310 are arranged differently, and two adjacent sub-pictures are arranged. The prime combination 230 has a different arrangement of the second color sub-pixel 320 and the third color sub-pixel 330. The above arrangement can also be applied to embodiments in which each row of pixels contains more first color sub-pixels 310 and more sub-pixel combinations 230.

In detail, if each row of pixels contains P first color sub-pixels 310 and P-1 sub-pixel combinations 230, and P is an integer greater than or equal to 3, the second row of the first row of pixels 210 -1 The second color sub-pixel 320 is adjacent to the 2s-1 second color sub-pixel 320 of the second row of pixels 220, and the second s third color sub-pixel of the first row of pixels 210 330 is adjacent to the 2sth third color subpixel 330 of the second row of pixels 220, where s is a positive integer and 2s is not greater than P-1.

Please refer to FIG. 2 and FIG. 3 . FIG. 2 is a schematic diagram of the display panel 200 displaying the first half-resolution screen 410 in the first time period. FIG. 3 is a schematic diagram showing the second half-resolution screen 420 displayed by the display panel in the second period. When the display panel 200 displays a picture, each of the sub-pixel combinations 230 may form a full-color pixel or a second side 232 adjacent to the first color sub-pixel 310 adjacent to the first side 231 thereof. The first color sub-pixel 310 constitutes a full-color pixel. The second side 232 is different from the first side 231. For each sub-pixel combination 230, the first color sub-pixel 310 adjacent to the first side 231 or its second side 232 in the first time period constitutes a full-color pixel, and is in the first The first color sub-pixel 310 adjacent to the other side 232 or 231 within the second time period constitutes another full color pixel.

For example, if a sub-pixel combination 230 forms a full-color pixel with the first color sub-pixel 310 adjacent to its first side 231 in the first time period, the sub-pixel combination 230 will be in the second The first color sub-pixel 310 adjacent to its second side 232 during the time period constitutes another full color pixel. Similarly, if a sub-pixel combination 230 forms a full-color pixel with the first color sub-pixel 310 adjacent to its second side 232 in the first time period, the sub-pixel combination 230 will be in the second time period. The first color sub-pixel 310 adjacent to its first side 231 constitutes another full color pixel. In an embodiment of the invention, the first time period and the second time period are respectively a frame period.

As shown in FIG. 2, in the first time period, each sub-pixel combination 230 of the first row of pixels 210 forms a full-color pixel with the first color sub-pixel 310 adjacent to the first side 231 thereof. (eg, full-color pixels P _{1, n} or P _{3, n} ), and each sub-pixel combination 230 of the second row of pixels 220 will have a first color sub-pixel 310 adjacent to its second side 232 Form a full-color picture (for example: full-color picture P _{2, n+1} or P _{4, n+1} ). Therefore, in the first time period, the full-color pixels P _1,n , P _3,n , P _2,n+1 and P _4,n+1 constitute the first half-resolution screen 410 described above. In this embodiment, the full-color pixels P _1,n , P _3,n , P _2,n+1 and P _4,n+1 constituting the first half-resolution screen 410 may be referred to as the first full The color picture is, and as shown in FIG. 2, the first full color pixels P _1,n , P _3,n , P _2,n+1 and P _4,n+1 are adjacent to each other.

As shown in FIG. 3, in the second time period, each sub-pixel combination 230 of the first row of pixels 210 forms a full-color pixel with the first color sub-pixel 310 adjacent to the second side 232 thereof. (eg, full-color pixels P _{2, n} or P _{4, n} ), and each sub-pixel combination 230 of the second row of pixels 220 will have a first color sub-pixel 310 adjacent to its first side 231 Form a full-color pixel (for example: full-color pixels P _{1, n + 1} or P _{3, n + 1} ). Therefore, in the second period, the full-color pixels P _2,n , P _4,n , P _1,n+1 and P _3,n+1 constitute the second half-resolution screen 420 described above.

In this embodiment, the full-color pixels P _2,n , P _4,n , P _1,n+1 and P _{3 ,n+1} constituting the second half-resolution screen 420 may be referred to as the second full The color picture is, and as shown in FIG. 3, the second full color pixels P _2,n , P _4,n , P _1,n+1 and P _3,n+1 are adjacent to each other. Since each sub-pixel combination 230 of the display panel 200 is driven together with the first color sub-pixel 310 on one side of the sub-pixel combination 230 in the first time period to display the first half-resolution picture 410 in the first time period The first full-color pixel is driven together with the first color sub-pixel 310 on the other side of the sub-pixel combination 230 in the second time period to display the second second-resolution image 420 in the second time period. Full-color pixels, so when the display panel 200 displays a plurality of first full-color pixels of the first half-resolution screen 410 and a plurality of second full-color pixels of the second half-resolution screen 420, the persistence through the vision The images can be combined into a full resolution picture having a higher resolution than the first half resolution screen 410 or the second half resolution screen 420.

In an embodiment of the invention, the display panel 200 includes a data driving unit and a scan driving unit. The data driving unit is configured to receive the image data, and write the image data into the first color sub-pixel 310, the second color sub-pixel 320 and the second pixel of the first row of pixels 210 and the second row of pixels 220 via the data line. Three-color sub-pixel 330. The scan driving unit is configured to output a plurality of scan signals via the scan line to turn on the corresponding first color sub-pixel 310, second color sub-pixel 320, and third color sub-pixel 330.

Please refer to FIG. 4 and refer to FIG. 1 at the same time. FIG. 4 is a schematic diagram of information for driving the display panel 200 of FIG. As described above, the data driving unit of the display panel 200 writes the image data into the first color sub-pixel 310, the second color sub-pixel 320, and the third color sub-pixel. 330. Further, when the data driving unit drives the first color sub-pixel 310, the second color sub-pixel 320, and the third color sub-pixel 330, the data driving unit divides the image data 250 into odd-numbered images. Data 251 and even-numbered image data 252. Wherein, in an odd period (such as the first period), the odd-numbered image data 251 is written into the odd-order pixels (such as the first row of pixels 210), and the even-ordered image data 252 is written into the even-order pixels ( Such as the second row of pixels 220). In even time periods (such as the second time period), the even-numbered image data 252 is written into the odd-order pixels (such as the first row of pixels 210), and the odd-order image data 251 is written into the even-numbered pixels (eg, The second row of pixels 220).

During an odd period of time, the image data of the even-numbered image data 252 used to drive the odd-order pixels (eg, the first row of pixels 210) is not written into the odd-order pixels (eg, the first row of pixels 210). The image data of the odd-numbered image data 251 for driving the even-numbered pixels (such as the second row of pixels 220) is not written into the even-order pixels (such as the second row of pixels 220); similarly, In an even period of time, the image data used to drive the odd-order pixels (such as the first row of pixels 210) in the odd-numbered image data 251 is not written into the odd-order pixels (such as the first row of pixels 210). The image data used to drive even-numbered pixels (such as the second row of pixels 220) in the even-numbered image data 252 is not written to the even-order pixels (eg, the second row of pixels 220). The display panel 200 displays the first half-resolution screen 410 and the second half-resolution screen 420 in the first period and the second period, respectively, and can be combined into a full-resolution screen through visual persistence. The display panel 200 having the limited pixel density presents a full-resolution screen having a higher resolution than the first half-resolution screen 410 or the second half-resolution screen 420.

However, the driving method of the odd-numbered period and the even-numbered period may also be reversed. For example, in an even-numbered period, the odd-numbered image data 251 is written into the odd-order pixels (eg, the first row of pixels 210), and the even-numbered image data 252 is written. Even-numbered pixels (such as the second row of pixels 220). In the odd-numbered period, the even-numbered image data 252 is written into the odd-order pixels (such as the first row of pixels 210), and the odd-numbered image data 251 is written into the even-order pixels (such as the second row of pixels 220).

In an embodiment of the invention, the display panel 200 can be a liquid crystal display or an organic light emitting diode display (OLED). In addition, among the red, green and blue colors, the human eye is most sensitive to green light, followed by red light and least sensitive to blue light. In an embodiment of the invention, the first color sub-pixel 310 may be, for example, a green sub-pixel, the second color sub-pixel 320 may be, for example, a blue sub-pixel, and the third color sub-pixel 330 may be, for example, a red sub-pixel. In such a case, the horizontal position of the visual center of gravity can be effectively adjusted by the green sub-pixel, and the vertical position of the visual center of gravity can be effectively adjusted by the red sub-pixel, and the visual center of gravity can be adjusted with zero side effects. Achieve the best expected results to the target location. However, the colors corresponding to the first color sub-pixel 310, the second color sub-pixel 320, and the third color sub-pixel 330 of the present invention are not limited to the above settings. For example, the first color sub-pixel 310 can be, for example, a blue sub-pixel, the second color sub-pixel 320 can be, for example, a red sub-pixel, and the third color sub-pixel 330 can be, for example, a green sub-pixel.

Please refer to FIG. 5. FIG. 5 is a flow chart of driving the display panel 200 according to an embodiment of the present invention. The driving method includes displaying the first half-resolution screen 410 in the first time period through the display panel 200 (step S510) and displaying the second half-resolution screen 410 in the second time period through the display panel 200 (step S520) to transmit the vision. The temporary combination is a full resolution screen.

As shown in FIG. 6, step S510 includes steps S512 and S514. In step S512, each sub-pixel combination 230 of the first row of pixels 210 and the first color sub-pixel 310 at the first side 231 of each sub-pixel combination 230 are driven to synthesize the first row. A plurality of first full-color pixels of the pixel 210 (eg, full-color pixels P _{1, n} , P _{3, n} ). In step S514, each sub-pixel combination 230 of the second row of pixels 220 and the first color sub-pixel 310 at the second side 232 of each sub-pixel combination 230 are driven to synthesize the second row. A plurality of first full-color pixels of the pixel 220 (eg, full-color pixels P _{2, n+1} , P _{4, n+1} ).

Further, as shown in FIG. 7, step S520 includes steps S522 and S524. In step S522, each sub-pixel combination 230 of the first row of pixels 210 and the first color sub-pixel 310 at the second side 232 of each sub-pixel combination 230 are driven to synthesize the first row. A plurality of second full-color pixels of the pixel 210 (eg, full-color pixels P _{2, n} , P _{4, n} ). In step S524, each sub-pixel combination 230 of the second row of pixels 220 and the first color sub-pixel 310 at the first side 231 of each sub-pixel combination 230 are driven to synthesize the second row. A plurality of second full-color pixels of the pixel 220 (eg, full-color pixels P _{1, n+1} , P _{3, n+1} ).

As can be seen from the above description, in the first time period, the driven first color sub-pixel 310 is the first color sub-pixel 310 and the second pixel 220 in the first row of pixels 210 located at the first side 231. The first color sub-pixel 310 is located at the second side 232. In the second time period, the driven first color sub-pixel 310 is the first color sub-pixel 310 of the first row of pixels 210 located at the second side 232 and the second row of pixels 220 is located at the first side The first color sub-pixel 310 of 231. Therefore, in the first period, the first first sub-pixels 310 of the first row of pixels 210 except the last first color sub-pixel 310 are driven, and the second row of pixels 220 is the first one except the first one. The other first color sub-pixels 310 of one color sub-pixel 310 are all driven. In contrast, in the second period, the first first color sub-pixels 310 of the first row of pixels 210 except the first first color sub-pixel 310 are driven, and the second row of pixels 220 except the last one. The other first color sub-pixels 310 of the first color sub-pixel 310 are all driven.

In contrast, in the second period, the first color sub-pixel 310 driven in the first row of pixels 210 is compared to the first color sub-pixel 310 driven in the second row of pixels 220. The length L ₂ of one sub-pixel combination 230 is offset in the two directions x. Since the first color sub-pixel 310 driven in the first row of pixels 210 and the first color sub-picture driven in the second row of pixels 220, whether in the first time period or in the second time period The prime 310 is staggered rather than completely aligned, so that by visual persistence, the user can visually feel a more detailed picture.

In addition, in order to further enhance the visual experience of the user, the visual weights of the first color sub-pixel 310, the second color sub-pixel 320, and the third color sub-pixel 330 may be adjusted, and each full-color pixel is adjusted.

Further, it is assumed that the visual weights of the first color sub-pixel 310, the second color sub-pixel 320, and the third color sub-pixel 330 are ω ₁ , ω _{2 ,} and ω ₃ , respectively, and the visual centers C _{1, n} , C ₂ The coordinates of _n , C _{3, n} and C _1,n+1 are (X _C1 , Y _C1 ), (X _C2 , Y _C2 ), (X _C3 , Y _C3 ) and (X _C4 , Y _C4 ), respectively. The visual weight of each of the sub-pixels is substantially equal to the product of its area and its brightness. In detail, the visual weight ω ₁ of the first color sub-pixel 310 is substantially equal to the product of the area of the first color sub-pixel 310 and the brightness of the first color sub-pixel 310, and the visual of the second color sub-pixel 320 The weight ω ₂ is substantially equal to the product of the area of the second color subpixel 320 and the luminance of the second color subpixel 320, and the visual weight ω ₃ of the third color subpixel 330 is substantially equal to the third color subpixel The product of the area of 330 and the brightness of the third color sub-pixel 330.

In addition, the coordinates X _C1 of the visual center C _1,n in the second direction x are equal to the sum of the products of the sub-pixels in the second direction x and the corresponding visual weights of the full-color pixels P _1,n . The sum of the visual weights; and the coordinate X _{C2 of the} visual center C _2n in the second direction x is equal to the coordinates of the full color pixels P _{2, n} in the second direction x and the corresponding visual weights The sum of the products divided by the sum of the visual weights. Therefore, if O ₁ is the origin, then

In order to obtain the best visual effect in the horizontal position, the distance d ₁ must be equal to half the sum of the width W _{1 of the} first color sub-pixel 310 and the length L ₂ of the second color sub-pixel 320 (ie equal to the first The length of the sub-pixel 310 is L ₁ ), so if O ₁ is the origin, then

Therefore, the sum of the visual weight of the second color subpixel and the visual weight of the third color subpixel is substantially equal to the visual weight of the first color subpixel.

The coordinate Y _C1 of the visual center C _1,n in the first direction y is equal to the sum of the product of the coordinates of the sub-pixels in the first direction y and the corresponding visual weights of the full-color pixels P _1,n divided by The sum of the visual weights; and the coordinate Y _{C3 of the} visual center C _3n in the first direction y is equal to the product of the coordinates of the sub-pixels in the first direction y and the corresponding visual weights in the full-color pixel P _{3 ,n} And divide by the sum of the visual weights. Therefore, if O ₁ is the origin, then

In addition, in order to obtain the best visual effect in the vertical position, the offset P ₁ is equal to 0, so if O ₁ is the origin, then

Thus, the width W of a second color sub-pixel 320 is ₂ and the width W of the third color sub-pixel 330 is substantially equal to the ratio of ₃ second color sub-pixel 320 Visual weights [omega] ₂ and the third color sub-pixel 330 The ratio of the visual weight ω ₃ .

The coordinate Y _C4 of the visual center C _1,n+1 in the first direction y is equal to the product of the coordinates of the sub-pixels in the first direction y and the corresponding visual weights in the full-color pixels P _1,n+1 . And divide by the sum of the visual weights. Therefore, if the center O ₂ of the first first color sub-pixel 310 of the second row of pixels 220 is taken as the origin, then ,and

In addition, in order to obtain the best visual effect, the distance d ₃ between two vertically adjacent full-color pixels (such as full-color pixels) must be equal to L ₁ , so if O ₂ is the origin, then

When the above equations (1), (2), and (3) are all established, the display panel 200 can have an optimum visual effect.
