Description

Array substrate and display device

Technical Field

The application relates to the field of display, in particular to an array substrate and a display device.

Background

At present, the number of chips of the tri-gate transistor architecture is only one third of that of a gate-drain architecture, so that the cost of the display panel can be obviously reduced and the product benefit can be improved by adopting the tri-gate transistor architecture; thus, the tri-gate transistor architecture has become preferred by panel manufacturers worldwide due to its superior characteristics.

However, the charging time of the tri-gate transistor pixel is only one third of that of the one-gate-one-drain pixel, and the charging time is shortened, which easily causes insufficient charging of the pixel, especially in RG (red and yellow), RB (red and blue), and GB (yellow and blue) mixed color images, and color shift problems are easily caused due to the charging difference between sub-pixels, such as: in the RG color mixed picture (yellow), the charging rate of the G pixel is larger than that of the R pixel, so that the brightness of the G pixel is larger than that of the R pixel, which causes the RG color mixed picture (yellow) to be greenish, thereby causing a color shift problem and affecting the display effect of the panel.

Therefore, how to solve the technical problem of color shift caused by the charging difference between the factor pixels is a difficult problem for panel manufacturers all over the world to try to overcome.

In the description of the present application, it is to be understood that the terms "length," "width," "thickness," "upper," "lower," and the like, as used herein, refer to an orientation or positional relationship as shown in the drawings, which is used for convenience in describing the present application and to simplify the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be taken as limiting the present application. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between.

Specifically, referring to fig. 1, fig. 1 is a schematic view of a first structure of an array substrate provided in the present embodiment, and as shown in fig. 1, an array substrate 10 provided in the present embodiment includes a pixel unit 101, where the pixel unit 101 includes a plurality of display pixels 1011 arranged in an array, each of the display pixels 1011 includes a first display pixel 1011a and a second display pixel 1011b, and the first display pixel 1011a and the second display pixel 1011b are vertically arranged.

The first display pixel 1011a and the second display pixel 1011b each include a first sub-pixel 10111, a second sub-pixel 10112 and a third sub-pixel 10113; and the sub-pixels in the first display pixel 1011a are vertically arranged in sequence as a first sub-pixel 10111, a second sub-pixel 10112 and a third sub-pixel 10113, and the sub-pixels in the second display pixel 1011b are vertically arranged in sequence as a first sub-pixel 10111, a third sub-pixel 10113 and a second sub-pixel 10112.

As can be understood, each column of the pixel unit 101 is circularly arranged with the display pixels 1011, wherein the display pixels 1011 each include a first display pixel 1011a and a second display pixel 1011b which are vertically arranged in sequence; and the sub-pixels in the same row of the pixel unit 101 have the same color; that is, the sub-pixels in the same row are all one of the first sub-pixel 10111, the second sub-pixel 10112 and the third sub-pixel 10113; that is, the sub-pixels in the same row are all the first sub-pixels 10111, or the sub-pixels in the same row are all the second sub-pixels 10112, or the sub-pixels in the same row are all the third sub-pixels 10113.

In one embodiment, the first sub-pixel 10111, the second sub-pixel 10112 and the third sub-pixel 10113 are horizontally disposed.

However, it can be understood that, in the color mixing picture, only two of the sub-pixels are turned on, and therefore, only the charging status of the turned-on sub-pixels needs to be considered.

Referring to fig. 2, fig. 2 is a charging status diagram of display pixels in the array substrate according to the embodiment of the present disclosure, as shown in fig. 2, fig. 2 is a color-mixed picture formed by the second sub-pixel 10112 and the third sub-pixel 10113, at this time, the second sub-pixel 10112 and the third sub-pixel 10113 are turned on, the first sub-pixel 10111 is turned off, the groove 10112a on the row G2 represents a charging status of the second sub-pixel 10112 in the first display pixel 1011a, the groove 10113a on the row G3 represents a charging status of the third sub-pixel 10113 in the first display pixel 1011a, the groove 10112b on the row G5 represents a charging status of the third sub-pixel 10113 in the second display pixel 1011b, and the groove 10113b on the row G6 represents a charging status of the second sub-pixel 10112 in the second display pixel 1011 b.

It is understood that the charging condition of each sub-pixel can be obtained by observing the size of the groove, wherein the larger the groove, the more saturated the charging is proved, and the smaller the groove, the less sufficient the charging is proved. The grooves 10112a on the G2 row and the grooves 10112b on the G5 row are smaller, and the grooves 10112a on the G2 row and the grooves 10112b on the G5 row have the same size; the groove 10113a on row G3 is larger than the groove 10113b on row G6, and the groove 10113a on row G3 is the same size as the groove 10113b on row G6. Therefore, in one display pixel 1011, there is one of the second subpixel 10112 and the third subpixel 10113 that are fully charged, and there is one of the second subpixel 10112 and the third subpixel 10113 that are not fully charged.

However, in the conventional technique, the sub-pixels in the display pixels are arranged in the same order, so that in the mixed color image, the sub-pixel of one color to be displayed is always in an insufficiently charged state, and the sub-pixel of the other color to be displayed is always in a saturated state, thereby causing color shift. In the present application, by changing the arrangement order of the sub-pixels in the second display pixel 1011b, one of the second sub-pixel 10112 and the third sub-pixel 10113 that are charged to saturation is provided in one display pixel 1011, and one of the second sub-pixel 10112 and the third sub-pixel 10113 that are not charged to deficiency is provided, so that the luminance of the light emitted by the second sub-pixel 10112 and the third sub-pixel 10113 that are used for displaying are the same, and therefore, the color shift phenomenon does not occur in the color-mixed picture, and the uniformity of the display picture is improved.

Specifically, referring to fig. 1, fig. 3, and fig. 3 are schematic diagrams illustrating a first structure of a pixel unit according to an embodiment of the present disclosure, as shown in fig. 3, a pixel unit 101 according to an embodiment of the present disclosure includes a plurality of display pixels 1011 arranged in an array, each of the display pixels 1011 includes a first display pixel 1011a and a second display pixel 1011b, and the first display pixel 1011a and the second display pixel 1011b are vertically arranged, each of the first display pixel 1011a and the second display pixel 1011b includes a first sub-pixel 10111, a second sub-pixel 10112, and a third sub-pixel 10113, sub-pixels in the first display pixel 1011a are vertically arranged in sequence to be the first sub-pixel 10111, the second sub-pixel 10112, and the third sub-pixel 10113, and sub-pixels in the second display pixel 1011b are vertically arranged in sequence to be the first sub-pixel 10111, the third sub-pixel 10113, and the second sub-pixel 10112.

The first sub-pixel 10111 is a red sub-pixel, the second sub-pixel 10112 is a green sub-pixel, and the third sub-pixel 10113 is a blue sub-pixel.

It is to be understood that the red sub-pixel may be represented by R, the green sub-pixel may be represented by G, and the blue sub-pixel may be represented by B, when the pixel unit 101 shown in fig. 3 is applied to a green-blue mixed color picture, the red sub-pixel does not emit light, and only the green sub-pixel and the blue sub-pixel emit light, and then the charging condition of the pixel unit 101 is as shown in fig. 2. As can be seen from fig. 2, in one display pixel 1011, there is one of the second subpixel 10112 and the third subpixel 10113 that are fully charged, and there is one of the second subpixel 10112 and the third subpixel 10113 that are not fully charged. Therefore, in the green-blue mixed color picture, because the green sub-pixel and the blue sub-pixel have the same charging consistency, the brightness of the light emitted by the green sub-pixel and the blue sub-pixel is consistent due to the charging consistency of the green sub-pixel and the blue sub-pixel, the problem of color deviation of green or blue can not occur, and the display uniformity of the green-blue mixed color picture is improved.

In one embodiment, the first sub-pixel 10111 is a red sub-pixel, the second sub-pixel 10112 is a blue sub-pixel, and the third sub-pixel 10113 is a green sub-pixel, because only the colors of the second sub-pixel 10112 and the third sub-pixel 10113 are exchanged, as can be seen from fig. 2, in one display pixel 1011, there is one of the second sub-pixel 10112 and the third sub-pixel 10113 that are charged to saturation, and there is one of the second sub-pixel 10112 and the third sub-pixel 10113 that are not charged to deficiency, so there is only one of the green sub-pixel and the blue sub-pixel that are charged to deficiency, and therefore, in the green-blue picture, the green sub-pixel and the blue sub-pixel have the same charging performance as before, and the luminance of the emitted light is the same, and therefore, the color mixing problem of green bias or blue bias does not occur, thereby improving the uniformity of the display of the green-blue mixed color picture.

Specifically, please refer to fig. 1, fig. 4 is a second schematic structural diagram of the pixel unit provided in the embodiment of the present application, as shown in fig. 4, the pixel unit 101 provided in the embodiment of the present application includes a plurality of display pixels 1011 arranged in an array manner, the display pixels 1011 include first display pixels 1011a and second display pixels 1011b, and the first display pixels 1011a and the second display pixels 1011b are vertically arranged, the first display pixels 1011a and the second display pixels 1011b include first sub-pixels 10111, second sub-pixels 10112 and third sub-pixels 10113, the sub-pixels in the first display pixels 1011a are vertically arranged in sequence to form first sub-pixels 10111, second sub-pixels 10112 and third sub-pixels 10113, the sub-pixels in the second display pixels 1011b are vertically arranged in sequence to form first sub-pixels 10111, third sub-pixels 10113 and second sub-pixels 10112. The first sub-pixel 10111 is a green sub-pixel, the second sub-pixel 10112 is a red sub-pixel, and the third sub-pixel 10113 is a blue sub-pixel.

It is to be understood that the red sub-pixel may be represented by R, the green sub-pixel may be represented by G, and the blue sub-pixel may be represented by B, and when the pixel unit 101 shown in fig. 4 is applied to a red-blue mixed color picture, the green sub-pixel does not emit light, and only the red sub-pixel and the blue sub-pixel emit light. As can be seen from fig. 2, in one display pixel 1011, there are one of the second subpixel 10112 and the third subpixel 10113 that are fully charged, and there are one of the second subpixel 10112 and the third subpixel 10113 that are not fully charged. Therefore, in the red and blue mixed color picture, because the red sub-pixel and the blue sub-pixel have the same charging consistency, the brightness of the light emitted by the red sub-pixel and the light emitted by the blue sub-pixel are consistent, the problem of color deviation towards red or blue is avoided, and the display uniformity of the red and blue mixed color picture is improved.

In one embodiment, the first sub-pixel 10111 is a green sub-pixel, the second sub-pixel 10112 is a blue sub-pixel, and the third sub-pixel 10113 is a red sub-pixel, because only the colors of the second sub-pixel 10112 and the third sub-pixel 10113 are exchanged, as can be seen from fig. 2, in one display pixel 1011, there is one of the second sub-pixel 10112 and the third sub-pixel 10113 that are charged to saturation, and there is one of the second sub-pixel 10112 and the third sub-pixel 10113 that are not charged to deficiency, so that there is only one of the red sub-pixel and the blue sub-pixel that are charged to deficiency, and therefore, in the red-blue mixed color picture, the red sub-pixel and the blue sub-pixel have the same charging performance as before, and the luminance of the emitted light of the red sub-pixel and the blue sub-pixel are also the same, and therefore, the red-blue color shift problem does not occur, thereby improving the uniformity of the red and blue mixed color picture display.

Specifically, referring to fig. 1, fig. 5, and fig. 5 are schematic views of a third structure of a pixel unit provided in the present embodiment, as shown in fig. 5, a pixel unit 101 provided in the present embodiment includes a plurality of display pixels 1011 arranged in an array, each of the display pixels 1011 includes a first display pixel 1011a and a second display pixel 1011b, and the first display pixel 1011a and the second display pixel 1011b are vertically arranged, each of the first display pixel 1011a and the second display pixel 1011b includes a first sub-pixel 10111, a second sub-pixel 10112, and a third sub-pixel 10113, sub-pixels in the first display pixel 1011a are vertically arranged in sequence to form the first sub-pixel 10111, the second sub-pixel 10112, and the third sub-pixel 10113, and sub-pixels in the second display pixel 1011b are vertically arranged in sequence to form the first sub-pixel 10111, the third sub-pixel 10113, and the second sub-pixel 10112. The first sub-pixel 10111 is a blue sub-pixel, the second sub-pixel 10112 is a red sub-pixel, and the third sub-pixel 10113 is a green sub-pixel.

It is to be understood that the red sub-pixel may be represented by R, the green sub-pixel may be represented by G, and the blue sub-pixel may be represented by B, when the pixel unit 101 shown in fig. 5 is applied to a red-green color mixing picture, the blue sub-pixel does not emit light, and only the red sub-pixel and the green sub-pixel emit light. In addition, as can be seen from fig. 2, in one display pixel 1011, there is one of the second subpixel 10112 and the third subpixel 10113 which are fully charged, and there is one of the second subpixel 10112 and the third subpixel 10113 which are not fully charged. Therefore, in the red and green mixed color picture, the red sub-pixel and the green sub-pixel which are charged to saturation have one, and the red sub-pixel and the green sub-pixel which are not charged to deficiency have one, so that the brightness of the light emitted by the red sub-pixel and the brightness of the light emitted by the green sub-pixel are consistent due to the charging consistency of the red sub-pixel and the green sub-pixel, the problem of color deviation towards red or green can not occur, and the display uniformity of the red and green mixed color picture is improved.

In one embodiment, the first sub-pixel 10111 is a blue sub-pixel, the second sub-pixel 10112 is a green sub-pixel, and the third sub-pixel 10113 is a red sub-pixel, because only the colors of the second sub-pixel 10112 and the third sub-pixel 10113 are exchanged, as can be seen from fig. 2, in one display pixel 1011, there is one of the second sub-pixel 10112 and the third sub-pixel 10113 that are charged to saturation, and there is one of the second sub-pixel 10112 and the third sub-pixel 10113 that are not charged to deficiency, so that there is one of the green sub-pixel and the red sub-pixel that are charged to deficiency, and therefore, in the red and green mixed color picture, the green sub-pixel and the red sub-pixel have the same charging performance as before, and the luminance of the light emitted by the green sub-pixel and the red sub-pixel is also the same, and therefore, the green or red color shift problem does not occur, thereby improving the uniformity of the red and green mixed color picture display.

Of course, the first data line 1021 may be at a negative potential, and the second data line 1022 is at a positive potential, as long as the first data line 1021 and the second data line 1022 have opposite power polarities.

It can be understood that, with such an arrangement, the array substrate provided in the embodiment of the present application is applicable to a display panel using a flip pixel driving architecture, so that the arrangement order of sub-pixels in the display pixel can be changed, the charging difference of the sub-pixels can be reduced, the luminance difference of the sub-pixels can be reduced, the color shift problem of the display panel using the flip pixel driving architecture when a color-mixed picture is displayed can be further improved, and the display uniformity of the display panel using the flip pixel driving architecture can be improved.

In addition, the flip pixel driving structure means that in the pixel driving structure, the sub-pixels and the adjacent sub-pixels have opposite power supply polarities, wherein the adjacent two sub-pixels include not only the case that the two sub-pixels are adjacent in the vertical direction, but also the case that the two sub-pixels are adjacent in the horizontal direction.

Further, referring to fig. 8, fig. 8 is a fourth structural schematic diagram of the array substrate according to the embodiment of the present disclosure, as shown in fig. 8, the array panel 10 according to the embodiment of the present disclosure includes a first region 104a, a second region 104b, and a third region 104c disposed between the first region 104a and the second region 104b, where the third region 104c includes a first end 1041c and a second end 1042c disposed oppositely, the first end 1041c is an end of the third region 104c close to the data signal input end 10a of the array substrate 10, the second end 1042c is an end of the third region 104c far away from the data input end 10a of the array substrate 10, the first region 104a is disposed on the first end 1041c, and the second region 104b is disposed on the second end 1042 c.

A GOA driving circuit 105 is disposed outside the array substrate 10, and includes a first GOA driving sub-circuit 105a, a second GOA driving sub-circuit 105b, and a third GOA driving sub-circuit 105 c; the first GOA driver sub-circuit 105a corresponds to the first region 104a, the second GOA driver sub-circuit 105b corresponds to the second region 104b, and the third GOA driver sub-circuit 105c corresponds to the third region 104 c.

In one embodiment, the duty cycle of the clock signal of the first GOA driving sub-circuit 105a is 40/60, the duty cycle of the clock signal of the second GOA driving sub-circuit 105b is 50/50, and the duty cycle of the clock signal of the third GOA driving sub-circuit 105c is 45/55.

It can be understood that, as the distance from the data signal input end 10a of the array substrate 10 is farther, the charging rate of the pixels connected to the GOA driving sub-circuit 105 is gradually decreased due to the signal delay effect of the data line signal in the transmission process, so that the charging rate of the pixels connected to the GOA driving sub-circuit 105 is lower as the distance from the data signal input end 10a of the array substrate 10 is farther, and by changing the duty ratio of the clock signal of the GOA driving sub-circuit 105, the time that the gate signal of the GOA driving sub-circuit 105 is turned on is gradually increased as the distance from the data signal input end 10a of the array substrate 10 is farther, and the charging time of the pixels connected to the GOA driving sub-circuit 105 is gradually increased, so that the uniformity of the charging of the pixels in the array substrate 10 can be improved, and the color shift problem can be further improved.

In the array substrate provided by the application, by changing the arrangement sequence of the sub-pixels in the display pixels in the array substrate, the numbers of the sub-pixels with insufficient charging of each color and the sub-pixels of the charging group can be consistent when a color mixing picture is displayed, so that the charging difference among the sub-pixels with different colors can be changed, the brightness difference among the sub-pixels with different colors is reduced, and the color cast condition is further changed.
