Description

Method for adjusting image display quality on monitor and related monitor

technical field

The present invention relates to a display, in particular to a method for adjusting image display quality on the display and a related display.

Background technique

Organic light emitting diode (OLED) is a very novel display technology nowadays. Its light emitting principle is different from the existing well-known display technology, such as cathode ray tube (cathode ray tube, CRT), Super twist nematic (STN) liquid crystal display (liquid crystal display, LCD), plasma display panel (plasma display panel, PDP), field emission display (field emission display, FED), monocrystalline silicon liquid crystal display panel (liquid crystal on silicon, LCOS), and light emitting diode (light emitting diode, LED), etc. Organic light-emitting diodes use organic materials to form a light-emitting diode element, which itself has the characteristic of actively emitting light. With the rapid development of the existing manufacturing process, organic light-emitting diode technology is also widely used in display products. Because organic light-emitting diodes have the characteristics of active light emission, other components of the product can be reduced, and product costs can be greatly reduced. Therefore, it is very suitable for on next-generation displays.

During the manufacturing process of existing flat panel display products, the resolution of the display cannot be too high due to the limitation of the process conditions and the precision of the machine. Taking organic light emitting diodes as an example, in the process of manufacturing organic light emitting diode products, because organic materials are manufactured by evaporation method, metal shield mask (metal shield mask) needs to be used, which is not in the well-known semiconductor manufacturing process. In the photomask photodevelopment technology, the precision of the metal shield cannot be compared with that of the photomask, so the resolution of the OLED product cannot be too high. For example, the existing technology can only achieve about 120-150 display pixels per inch, that is, about 120-150ppi, thus reducing the competitiveness of OLED products in terms of screen resolution.

The traditional image display method is to display the image signal on a display with the same resolution. Please refer to FIG. 1 , the right half of FIG. 1 shows an image signal 12 , and the left half shows a display 10 with a corresponding resolution. The image signal 12 is transmitted to the display 10 by an electronic system. For example, if the resolution of the display 10 is nxm, that is, the display 10 includes n horizontal pixel rows (display pixel row), and each pixel row includes mx3 sub-pixels (display sub-pixel), where " x3" means that each pixel contains sub-pixels of three primary colors of red (R), green (G), and blue (B). The electronic system must transmit each picture, that is, the image signal 12 (which also includes nxmx3 pen data) to the pixel position corresponding to the display 10 in a one-to-one manner, so as to present a complete picture on the display 10 superior. As shown in FIG. 1 , the first, second, third, and fourth pixels on the first pixel row of the image signal 12 are respectively displayed on the first, second, third, third, and fourth pixels on the first pixel row of the display 10. and the fourth pixel, and the nth pixel column of the image signal 12 is displayed on the nth pixel column of the display 10, therefore, the resolution of the display 10 and the image signal 12 have a 1:1 relationship.

However, with the development trend of display product applications, the amount of information displayed on the display is gradually increasing, and the requirements for the display are also getting higher and higher, especially in terms of screen resolution. The higher the screen resolution requirements, the more pixels the display must have. In this way, the interval between each pixel will become smaller and smaller, and even exceed the process limit of the machine. Therefore, the high-quality flat-panel display products The manufacturing feasibility and yield of the resolution are getting lower and lower.

Please refer to FIG. 2 , the right half of FIG. 2 also shows the image signal 12 , but the left half shows another display 20 whose resolution does not correspond to the image signal 12 . Specifically, the resolution of the display 20 is only nxm/6, that is to say, the display 20 only includes n/2 horizontal pixel rows, and each pixel row only includes mx3/3 sub-pixels, similarly, "x3 " also means that each pixel contains sub-pixels of the three primary colors of red (R), green (G), and blue (B). Since the resolution of the display 20 is only one-sixth of the resolution of the display 10 shown in FIG. On the location point, on the contrary, only part of the data in the image signal 12 can be displayed on the pixel location point corresponding to the display 20 . As shown in FIG. 2 , during the actual display period (shown in FIG. 6 ), the first and fourth pixels in the first pixel column of the image signal 12 can be displayed on the first pixel column of the display 20 respectively. 1, and the second pixel, but the second, and the third pixel do not have corresponding pixels on the first pixel column of the display 20, so they have to be discarded; on the other hand, the (n-1th pixel of the image signal 12 ) pixel row can be displayed on the n/2th pixel row of the display 20, but the nth pixel row has to be discarded because there is no corresponding pixel row on the display 20.

The method for adjusting image display quality on a display and the related display of the present invention utilize the characteristic that each pixel on the display includes a plurality of sub-pixels, and divide the plurality of pixels contained in the image signal one by one by dividing the clock method and the pixel row weighting method Sub-pixel by sub-pixel is displayed on the display to improve the image display quality on the display.

Please refer to FIG. 3 to FIG. 6 . FIG. 3 to FIG. 5 are schematic diagrams of the image signal 12 and the display 50 in the first embodiment of the present invention, and FIG. 6 is an operation timing diagram of the display 50 . The display 50 includes n horizontal pixel columns, but unlike the display 20, each pixel column only includes mx3/3 sub-pixels, and each pixel column of the display 50 includes red (R) sub-pixels in addition to mx3/3 sub-pixels. A pixel 52, and a green (G) sub-pixel 54. Similarly, each pixel of the display 50 also includes three primary color sub-pixels of red (R), green (G), and blue (B) arranged in sequence.

In the first embodiment of the present invention, the display 50 includes a display panel 56 , a receiving unit 58 , and a control unit 60 , as shown in FIG. 12 , which is a functional block diagram of the display 50 . The display panel 56 includes n pixel rows, each pixel row includes m/3 pixels and two sub-pixels, and each pixel includes 3 sub-pixels; the receiving unit 58 is used to receive the image signal 12, and the image signal 12 includes n Each pixel row includes m pixels, and each pixel includes 3 sub-pixels; the control unit 60 is used to display each pixel contained in the image signal received by the receiving unit 58 on a sub-pixel basis on the display panel 56.

The operation process of the display 50 is described as follows. During the first sub-display period sub-frame1 (the first sub-display period sub-frame1 is about one-third of the actual display period frame), the first pixel in the first pixel column of the image signal 12 is still displayed on the display 50 The first pixel in the first pixel column of the image signal 12, that is to say, the R, G, and B image sub-signals in the first pixel of the first pixel column of the image signal 12 are respectively displayed on the first pixel column of the display 50 On the red (R), green (G) and blue (B) sub-pixels in the first pixel, as shown in Figure 3; , and the third pixel is discarded, in the second sub-display period sub-frame2 (the second sub-display period sub-frame2 is also about one-third of the actual display period frame), the image signal 12 displayed on the display 50 The second pixel in the first pixel column of the display 50 is the green (G) and blue (B) sub-pixels in the first pixel of the first pixel column displayed on the display 50, and the red (R) sub-pixel in the second pixel 4, in detail, the green (G) and blue (B) sub-pixels in the first pixel of the first pixel column of the display 50 and the red (R) sub-pixel in the second pixel Green (G), blue (B), and red (R) sub-pixels included in the second pixel of the first pixel column that respectively display the image signal 12; in addition, in a third sub-display period sub-frame3 (the The third sub-display period sub-frame3 is also about one-third of the actual display period frame), the third pixel in the first pixel column of the image signal 12 displayed on the display 50 is displayed on the first pixel of the display 50 The blue (B) sub-pixel in the first pixel of the column, and the red (R) and green (G) sub-pixels in the second pixel, as shown in FIG. 5 .

By analogy, in the first sub-display period sub-frame1, the fourth, seventh..., and (m-2)th pixels in the first pixel column of the image signal 12 are respectively displayed on the first pixel of the display 50 The second, the third..., and the (m/3) pixel in the column, as shown in Figure 3; the fifth, the eighth..., and the (m-1) pixel in the first pixel column of the image signal 12 The pixels are respectively displayed on the green (G) and blue (B) sub-pixels in the second pixel of the first pixel column of the display 50, the red (R) sub-pixel in the third pixel, the green (G) in the third pixel ) and blue (B) sub-pixels and the red (R) sub-pixels in the fourth pixel..., and the green (G) and blue (B) sub-pixels in the (m/3) pixel and the display 50 compared to the display 20 On the additionally added red (R) sub-pixel 52; the sixth, the ninth..., and the m-th pixel in the first pixel column of the image signal 12 are respectively displayed in the second pixel of the first pixel column of the display 50 Blue (B) sub-pixel and red (R) and green (G) sub-pixel in the third pixel, blue (B) sub-pixel in the third pixel and red (R) and green (G) in the fourth pixel The sub-pixels..., and the blue (B) sub-pixel in the (m/3)th pixel and the additional red (R) sub-pixel 52 and green (G) sub-pixel 54 of the display 50 compared with the display 20 .

Equivalently, the image signal 12 is divided into three image sub-signals (the first image sub-signal 14 contains the image signals of the first, fourth, seventh... points in the horizontal direction of the image signal 12, and the second image sub-signal 16 contains The image signal of the second, fifth, eighth... point in the horizontal direction of the image signal 12, the third image sub-signal 18 includes the image signal of the third, sixth, ninth... point in the horizontal direction of the image signal 12), the display 50 In the first sub-display period sub-frame1 is the first image sub-signal 14 of the display image signal 12, and the display 50 is the second image sub-signal 16 of the display image signal 12 in the second sub-display period sub-frame2. In the third sub-display period sub-frame3, the third image sub-signal 18 of the image signal 12 is displayed, so as to display the complete image signal 12 repeatedly, as shown in FIG. 7 . In this way, although each pixel column of the display 50 only includes m/3 pixels and two sub-pixels, and m/3 is one third of the number m of pixels contained in each pixel column of the image signal 12, but Since the display 50 displays each pixel included in the image signal 12 sub-pixel by sub-pixel instead of pixel-by-pixel, equivalently, the resolution of the display 50 in the horizontal direction is the same as the resolution of the image signal 12 in the horizontal direction. . On the other hand, the resolution of the display 50 is three times the resolution of the display 20, although the number of pixels contained in each pixel column of the display 50 is the same as the number of pixels contained in each pixel column of the display 20. number.

In the first embodiment of the present invention, each pixel of the display 50 is assumed to contain only three sub-pixels, that is, red (R), green (G), and blue (B) sub-pixels, and these three sub-pixels are It is arranged in a straight line, that is, the red (R) sub-pixel is first, followed by the green (G) sub-pixel, and finally the blue (B) sub-pixel. However, in the display of the present invention, each pixel It is not necessarily necessary to include exactly three sub-pixels, and may include more than three sub-pixels. For example, each pixel of the display of the present invention may include not only red (R), green (G), and blue (B) sub-pixels, but also white (W) sub-pixels. In addition, in the display of the present invention, the sub-pixels contained in each pixel do not have to be arranged in a straight line. For example, in addition to the sub-pixels contained in each pixel of the display of the present invention can be arranged in a regular triangle In addition, they can also be arranged in a linear or square shape, as shown in Figures 8A, 8B and 8C. In FIG. 8A, each pixel of the display of the present invention includes three sub-pixels arranged in a regular triangle shape. In FIG. 8B, each pixel of the display of the present invention includes four sub-pixels arranged in a straight line. In FIG. 8C , each pixel of the display of the present invention includes four sub-pixels arranged in a square shape.

In addition, in addition to dividing the actual display period frame into three approximately equal sub-display periods to display the first, second, and third image sub-signals 14, 16, and 18, the display of the present invention can also divide the actual The display period frame is divided into three unequal sub-display periods, or divided into two equal or unequal sub-display periods. Taking the actual display period frame divided into two equal sub-display periods as an example, in the fourth sub-display period (the fourth sub-display period is about half of the actual display period frame), the image signal 12 The first image sub-signal (which comprises the image signal of the first, third, fifth... point in the horizontal direction of the image signal 12) is respectively displayed on the first, second, third... pixel of the display of the present invention, On the other hand, in the fifth sub-display period (the fifth sub-display period is also about 1/2 of the actual display period frame), the second image sub-signal of the image signal 12 (which includes the horizontal direction of the image signal 12 The image signals of the second, fourth, sixth... points) are respectively displayed on the blue (B) sub-pixel in the first pixel of the display of the present invention and the red (R) and green (G) sub-pixels in the second pixel On the blue (B) sub-pixel in the second pixel and the red (R) and green (G) sub-pixels in the third pixel On the blue (B) sub-pixel in the third pixel and in the fourth pixel On the red (R) and green (G) sub-pixels... (certainly, in the fifth sub-display period, the second image sub-signal of the image signal 12 can also be respectively displayed on the green in the first pixel of the display of the present invention (G) and blue (B) sub-pixels and red (R) sub-pixels in the second pixel, green (G) and blue (B) sub-pixels in the second pixel and red (R) in the third pixel on the sub-pixels, on the green (G) and blue (B) sub-pixels in the third pixel, and on the red (R) sub-pixel in the fourth pixel...). In this way, the resolution of the display of the present invention has a 1:2 relationship with the image signal 12 .

Furthermore, in the first embodiment of the present invention, each pixel column of the display 50 includes not only m/3x3 sub-pixels, but also a red (R) sub-pixel 52 and a green (G) sub-pixel 54, however, this Each pixel of the inventive display may also contain neither red (R) sub-pixel 52 nor green (G) sub-pixel 54 , or additionally only red (R) sub-pixel 52 . Specifically, if the display of the present invention neither includes red (R) sub-pixel 52 nor green (G) sub-pixel 54, then, in the first sub-display period sub-frame1, the first pixel of the image signal 12 The first, fourth, seventh..., and (m-2)th pixels in the column are still respectively displayed on the above-mentioned display that includes neither the red (R) sub-pixel 52 nor the green (G) sub-pixel 54 On the first, second, third..., and (m/3) pixels in the first pixel column; but in the second sub-display period sub-frame2, the second pixel in the first pixel column of the image signal 12 , the fifth, the eighth..., and the (m-4) pixels are still respectively displayed in the green (G) and blue (B) sub-pixels and the second pixel in the first pixel of the first pixel column of the above-mentioned display The red (R) sub-pixel in the second pixel, the green (G) and blue (B) sub-pixel in the second pixel and the red (R) sub-pixel in the third pixel, the green (G) and blue ( B) The red (R) sub-pixel in the sub-pixel and the fourth pixel..., and the green (G) and blue (B) sub-pixel in the (m/3)-1th pixel and the (m/3)th pixel red (R) sub-pixel, but because each pixel column of the above-mentioned display does not contain red (R) sub-pixel 52, so, in the second sub-display period sub-frame2, the first pixel column of the image signal 12 In the (m-1)th pixel, only the green (G) subpixel and the blue (B) subpixel are displayed in the (m/3)th pixel of the first pixel column of the above-mentioned display. (B) on the sub-pixel; similarly, in the third sub-display period sub-frame3, only the blue (B) sub-pixel in the mth pixel of the first pixel column of the image signal 12 is displayed on the first pixel of the above-mentioned display On the blue (B) sub-pixel in the (m/3)th pixel of the column.

Finally, please refer to FIG. 6 again. In FIG. 6, the third image sub-signal 18 is correspondingly displayed in the blue (B) sub-pixel in each pixel in the third sub-display period sub-frame3 and continues in the On the red (R) and green (G) sub-pixels in the pixels behind the pixel, but the first image sub-signal 14 in another image signal following the image signal 12 is in another first sub-display period sub-frame1 ( It is continued in the third sub-display period sub-frame3), and is correspondingly displayed on the red (R), green (G), and blue (B) sub-pixels in each pixel. However, the display of the present invention may also be based on an operation sequence different from that of the display 50 (that is, first (R, G, B), then (G, B, R), finally (B, R, G), and then back to ( R, G, B)) display image signal 12 . Please refer to FIG. 9 . FIG. 9 is an operation timing diagram of another display in the second embodiment of the present invention. As shown in Figure 9, when the third image sub-signal 18 is correspondingly displayed in the blue (B) sub-pixel in each pixel and the red in the pixel following the pixel in the third sub-display period sub-frame3 After the (R) and green (G) sub-pixels are on, the display in the second embodiment of the present invention will display another image signal following the image signal 12 in the reverse order of the image sub-signals, that is, its image The display order of the sub-signals is the third image sub-signal 18, the second image sub-signal 16, and the first image sub-signal 14, wherein the third image sub-signal 18 is still correspondingly displayed in the blue (B) sub-pixel and On the red (R) and green (G) sub-pixels in the pixels following the pixel, the second image sub-signal 16 is correspondingly displayed on the green (G) and blue (B) sub-pixels and On the red (R) sub-pixel in the pixels following the pixel, the first image sub-signal 14 is correspondingly displayed on each pixel. In this way, the image signal 12 can be blurred as much as possible.

The above method can improve the image display quality of the display of the present invention in the horizontal direction, and how to improve the image display quality of the display of the present invention in the vertical direction will be described below.

Please refer to FIG. 10 , which is a schematic diagram of the image signal 12 and the display 80 in the third embodiment of the present invention. Unlike the display 50 which includes n horizontal pixel rows, the display 80 only includes n/2 horizontal pixel rows. In addition, for the convenience of illustration, each pixel row of the display 80 includes m×3 sub-pixels.

Since the number of pixel columns included in the display 80 for displaying the image signal 12 is only 1/2 of the number of pixel columns included in the image signal 12, in order not to miss any pixel column data in the image signal 12 , in the third embodiment of the present invention, the pixel columns in the image signal 12 that do not correspond to the pixel columns of the display 80 are evenly displayed on the pixel columns of the display 80 .

The operation of the display 80 is described as follows. Since the second pixel column of the image signal 12 has no corresponding pixel column on the display 80, in the third embodiment of the present invention, one-half of the second pixel column of the image signal 12 is displayed on the display 80. 80 on the first pixel row (the first pixel row of the display 80 corresponds to the first pixel row of the image signal 12), and the remaining half of the second pixel row of the image signal 12 is displayed on the second pixel row of the display 80 On two pixel columns (the second pixel column of the display 80 corresponds to the third pixel column (3=2*2−1) of the image signal 12 ). Since the first pixel row of the display 80 needs to display the second pixel row of 1/2 of the image signal 12 in addition to the first pixel row that needs to display its corresponding image signal 12, therefore, in order to uniformize the display 80 The brightness of the displayed image signal 12, the first pixel column of the display 80 is displayed (the first pixel column of the image signal 12*1+the second pixel column of the image signal 12*1/2)/(1+1/ 2). As mentioned above, the remaining half of the second pixel column of the image signal 12 is displayed on the second pixel column of the display 80. In addition, the corresponding image signal 12 is displayed on the second pixel column of the display 80. The third pixel column of the image signal 12 and one-half of the fourth pixel column of the image signal 12. Similarly, in order to uniformize the brightness of the displayed image signal 12 on the display 80, the second pixel column of the display 80 is to display (the second pixel column of the image signal 12*1/2+the third pixel of the image signal 12 column*1+the fourth pixel column*1/2)/(1/2+1+1/2) of the image signal 12. By analogy, in addition to displaying the (k*2-1)th pixel row of the corresponding image signal 12 on the kth pixel row of the display 80, the (k*2-2)th pixel row of the image signal 12 is also displayed (one-half of the previous pixel row of the (k*2-1) pixel row of the image signal 12), and the (k*2) pixel row of the image signal 12 (the (k*2)th pixel row of the image signal 12 -1) one-half of the last pixel row of the pixel row), similarly, in order to normalize the brightness of the displayed image signal 12 on the display 80, the kth pixel row of the display 80 is to display (the first pixel row of the image signal 12 (k*2-2) pixel row*1/2+(k*2-1) pixel row*1+image signal 12 (k*2) pixel row*1/2)/( 1/2+1+1/2). Finally, on the n/2th pixel column of the display 80, except for the (n/2*2-1)th pixel column of the corresponding image signal 12, that is, the (n-1)th pixel column of the image signal 12 , and display the (n/2*2-2)th pixel column of the image signal 12 (that is, one-half of the (n-2) pixel column of the image signal 12), and the (n/2)th pixel column of the image signal 12 2*2) one-half of the pixel row (that is, the nth pixel row of the image signal 12), similarly, in order to normalize the brightness of the displayed image signal 12 on the display 80, the n/2th pixel of the display 80 The column is to display (the (n-2)th pixel column of the image signal 12*1/2+the (n-1)th pixel column of the image signal 12*1+the nth pixel column of the image signal 12*1/2)/ (1/2+1+1/2).

In this way, although the number of pixel columns included in the display 80 is only half of the number of pixel columns included in the image signal 12, the display 80 still uses 1/2 of the number of pixel columns included in the display through the aforementioned pixel column weighting method. Therefore, although the resolution of the display 80 has a 1:2 relationship with the image signal 12, the image display quality of the display 80 is improved through the pixel column weighting method.

In the third embodiment of the present invention, the k pixel column of the display 80 is the (2*k-1) pixel column corresponding to the image signal 12, however, the k pixel column of the display of the present invention may also correspond to The other pixel columns of the image signal 12 .

Please refer to FIG. 11 . FIG. 11 is a schematic diagram of the image signal 12 and the display 90 in the fourth embodiment of the present invention. Similarly, the display 90 also includes n/2 horizontal pixel rows, and for the convenience of illustration, each pixel row of the display 90 also includes m×3 sub-pixels.

Since the number of pixel columns included in the display 90 for displaying the image signal 12 is only 1/2 of the number of pixel columns included in the image signal 12, in order not to miss any pixel column data in the image signal 12 , in the fourth embodiment of the present invention, the pixel columns in the image signal 12 that do not correspond to the pixel columns of the display 90 are evenly displayed on the pixel columns of the display 90 .

The operation of the display 90 is described as follows. Since the first pixel row and the third pixel row of the image signal 12 have no corresponding pixel row on the display 90, in the fourth embodiment of the present invention, the first pixel row of the image signal 12 is divided into two One and half of the third pixel row of the image signal 12 is displayed on the first pixel row of the display 80, and the first pixel row of the display 80 is the second pixel row corresponding to the image signal 12 (2=1 *2). Because on the first pixel column of the display 90, in addition to the second pixel column that needs to display its corresponding image signal 12, it is necessary to display the first pixel column of 1/2 image signal 12 and the 1/2 image signal Therefore, in order to uniformize the brightness of the displayed image signal 12 on the display 90, the first pixel column of the display 90 is to display (the first pixel column of the image signal 12*1/2+image signal 12 The second pixel column*1+the third pixel column*1/2)/(1/2+1+1/2) of the image signal 12. By analogy, on the kth pixel column of the display 90, in addition to displaying the (k*2) pixel column of its corresponding image signal 12, the (k*2-1) pixel column of the image signal 12 (image One-half of the previous pixel column of the (k*2)th pixel column of the signal 12), and the (k*2+1)th pixel column of the image signal 12 (the (k*2)th pixel column of the image signal 12 One-half of the last pixel column of the column), similarly, in order to normalize the brightness of the displayed image signal 12 on the display 90, the kth pixel column of the display 90 is displayed (the (k*2th pixel column of the image signal 12 -1) pixel column *1/2+ (k*2) pixel column of image signal 12*1+ (k*2+1) pixel column of image signal 12*1/2)/(1/2+ 1+1/2). Finally, in addition to displaying the (n/2*2) pixel column corresponding to the image signal 12 on the n/2th pixel column of the display 90, that is, the nth pixel column of the image signal 12, the image signal is also displayed. 1/2 of the (n/2*2-1) pixel column of 12 (that is, the (n-1) pixel column of the image signal 12), similarly, in order to normalize the displayed image signal on the display 90 The brightness of 12, the n/2th pixel row of the display 90 is to display (the (n-1)th pixel row of the image signal 12*1/2+the nth pixel row*1 of the image signal 12)/(1/2+ 1).

In this way, although the number of pixel columns included in the display 90 is only half of the number of pixel columns included in the image signal 12, the display 90 still uses 1/2 of the number of pixel columns included in the display through the aforementioned pixel column weighting method. Therefore, although the resolution of the display 90 has a 1:2 relationship with the image signal 12, the image display quality of the display 90 is improved through the pixel column weighting method.

Compared with the prior art, the method for adjusting image resolution on a display and the related display of the present invention adopt the division clock method, the pixel row weighting method, and the pixel sharing (pixelsharing) method (that is, the image signal is divided into A plurality of pixels included in the display are displayed on the display sub-pixel by sub-pixel), therefore, even though the resolution of the display is not large enough, it is still possible to display the image data without losing any image data.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
