DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In the following, the technical scheme in the embodiment of the present application will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application. In addition, it should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. In the present application, in the absence of a contrary explanation, the location words used, such as “up” and “down”, usually refer to the up and down under the actual use or working state of the device, specifically the drawing direction in the attached drawings. The “inside” and “outside” are for the contour of the device.

The embodiments of the present application provide a display panel and a display device. The following are described in detail. It should be noted that an order of description of the following embodiments is not a limitation of the preferred order of the embodiments.

First, the embodiments of the present application provide a display panel. As shown in FIG. 1, the display panel 100 comprises a substrate 110. The substrate 110 is used as a bearing structure of the display panel 100 to support other functional film layers in the display panel 100 to ensure the structural stability of the display panel 100.

The substrate 110 is disposed with a plurality of scanning lines 121 and a plurality of data lines 130. The plurality of the scanning lines 121 extend along a first direction X and are arranged in parallel along a second direction Y. The plurality of the data lines 130 extend along the second direction Y and are arranged in parallel along the first direction X, and the first direction X is at an included angle with the second direction Y, that is, the plurality of scanning lines 121 and the plurality of data lines 130 are crossedly arranged on the substrate 110 in a distribution direction.

Among them, the first direction X can be defined as a column direction, and the second direction Y can be defined as a row direction, and the first direction X is perpendicular to the second direction Y. That is, the plurality of scanning lines 121 are distributed in multiple rows and the plurality of data lines 130 are distributed in multiple columns. Hence, the scanning lines 121 and the data lines 130 are distributed in multiple rows and multiple columns, so as to facilitate connection designs between subsequent structures and the scanning lines 121 and the data lines 130.

It should be noted that in the embodiments of the present application, the scanning lines 121 and the data lines 130 are located on different film layers of the display panel 100, and “crossedly arranged in the distribution direction” refers to a spatial cross, not a direct cross connection, so as to ensure that no electrical crosstalk occurs between the scanning lines 121 and the data lines 130.

The display panel 100 comprises a plurality of light-emitting components 120. The light-emitting components 120 are arranged on the substrate 110 in parallel along the second direction Y, that is, a distribution direction of the light-emitting components 120 is consistent with a distribution direction of the scanning lines 121. Each of the light-emitting components 120 comprises three scanning lines 121 and two light-emitting units 122 arranged in parallel along the second direction Y, that is, a light-emitting component 120 comprises the three scanning lines 121 and the two light-emitting units 122 distributed in rows. A position of the scanning lines 121 in one light-emitting component 120 relative to the light-emitting units 122 can be adjusted accordingly according to design requirements.

Each of the light-emitting units 122 comprises a plurality of light-emitting pixels 1221 arranged in parallel along the first direction X. And each of the light-emitting pixels 1221 comprises a plurality of sub light-emitting pixels 1221a arranged in parallel along the first direction X, that is, a distribution direction of the light-emitting pixels 1221 and a distribution direction of the sub light-emitting pixels 1221a in one light-emitting unit 122 are consistent with a distribution direction of the data lines 130. That is, one light-emitting component 120 comprises three scanning lines 121 and two rows of multi-column sub light-emitting pixels 1221a.

Each of the sub light-emitting pixels 1221a in one of the light-emitting components 120 are electrically connected with one of the scanning lines 121 in the one of the light-emitting components 120. By adjusting distribution modes of the three scanning lines 121 in the one of the light-emitting components 120, connection modes between the sub light-emitting pixels 1221a and the scanning lines 121 can be designed to prevent mutual interference between the plurality of sub light-emitting pixels 1221a while ensuring that the plurality of sub light-emitting pixels 1221a can all be electrically connected with one of the scanning lines 121.

It should be noted that when each of the sub light-emitting pixels 1221a is electrically connected with the one scanning line 121, the sub light-emitting pixel 1221a also needs to be electrically connected with one data line 130 at a same time to realize a regulation of light-emitting condition of the sub light-emitting pixel 1221a. By adjusting the distribution modes of the scanning lines 121 and the data lines 130, a regulation of the connection modes of the sub light-emitting pixels 1221a can be realized.

Alternatively, a number of the data lines 130 is less than a number of the sub light-emitting pixels 1221a in one of the light-emitting units 122, that is, the number of the data lines 130 is less than a number of columns of the sub light-emitting pixels 1221a. In the embodiments of the present application, one light-emitting component 120 comprises two light-emitting units 122 and three scanning lines 121. Compared with the traditional scanning lines 121 corresponding to each light-emitting unit 122, a layout number of the scanning lines 121 is increased, so that a layout number of the data lines 130 can be correspondingly reduced, and manufacturing cost of the scanning lines 121 is lower than that of the data lines 130, so that production cost of the display panel 100 can be reduced.

Wherein a product of the data lines 130 and the scanning lines 121 in the light-emitting component 120 is greater than or equal to a number of the sub light-emitting pixels 1221a in the light-emitting component 120. In an actual design process, each sub light-emitting pixel 1221a needs to be electrically connected with a scanning line 121 and a data line 130, and only one sub light-emitting pixel 1221a is connected with a same scanning line 121 and a same data line 130 at a same time, so as to realize an independent control of each sub light-emitting pixel 1221a. However, a plurality of sub light-emitting pixels 1221a can be connected to one scanning line 121 at a same time, and a plurality of sub light-emitting pixels 1221a can also be connected to one data line 130 at a same time, so as to reduce distribution numbers of the scanning lines 121 and the data lines 130 and simplify the distribution modes. By setting the product of the data lines 130 and the scanning lines 121 in one of the light-emitting components 120 to be greater than or equal to the number of the sub light-emitting pixels 1221a in one of the light-emitting components 120, it can be ensured that each sub light-emitting pixel 1221a in the one of the light-emitting component 120 can be electrically connected with the scanning line 121 and the data line 130.

In the embodiments of the present application, the distribution direction of the sub light-emitting pixels 1221a of the light-emitting units 122 is consistent with the distribution direction of the data lines 130, and the two light-emitting units 122 and the three scanning lines 121 form a light-emitting component 120, so that the sub light-emitting pixels 1221a in the light-emitting component 120 are respectively connected with one of the three scanning lines 121, and the number of the data lines 130 is less than the number of the sub light-emitting pixels 1221a of one of the light-emitting units 122. Hence, this structural design can increase the number of the scanning lines 121 and reduce a distribution number of the data lines 130, compared with the traditional structure in which the distribution modes of the scanning lines 121 and the data lines 130 are consistent with the distribution mode of the sub light-emitting pixels 1221a. And the manufacturing cost of the scanning lines 121 is lower than that of the data lines 130, which can reduce the overall production cost.

Alternatively, as shown in FIGS. 1 and 6, two scanning lines 121 of the light-emitting component 120 are arranged between the two light-emitting units 122 of the light-emitting component 120. Since the number of the data lines 130 is less than the number of the sub light-emitting pixels 1221a of one of the light-emitting units 122, that is, the number of the data lines 130 is less than the number of columns of the sub light-emitting pixels 1221a, one scanning line 121 cannot connect to a whole row of the sub light-emitting pixels 1221a at a same time. Arranging two of the three scanning lines 121 of the light-emitting component 120 between the two light-emitting units 122 is conducive to electrical connection between the light-emitting unit 122 and the adjacent scanning lines 121, so as to prevent mutual crosstalk in a connection process caused by a long distance between the scanning lines 121 and the sub light-emitting pixels 1221a in the light-emitting unit 122, which affects the regulation of the light-emitting condition of each sub light-emitting pixel 1221a.

One of the light-emitting units 122 of the light-emitting component 120 is arranged between the two scanning lines 121 of the light-emitting component 120, that is, the light-emitting component 120 has opposite sides in the second direction Y, and a remaining scanning line 121 in the light-emitting component 120 is arranged on one side edge of the light-emitting component 120 so that one of the two light-emitting units 122 is located between the two scanning lines 121. The remaining scanning line 121 is used to electrically connect with the sub light-emitting pixels 1221a in an adjacent light-emitting unit 122, so as to save a use of two scanning lines 121 between the two light-emitting units 122, and prevent that the sub light-emitting pixel 1221a far away from the scanning line 121 located on the one side edge of the light-emitting component 120 needs to be connected across pixels, thereby preventing mutual crosstalk between the sub light-emitting pixels 1221a.

Alternatively, in the second direction Y, two scanning lines 121 and one scanning line 121 are alternately arranged between two adjacent light-emitting units 122 in turn. That is, if the plurality of light-emitting components 120 are regarded as a whole, one side edge of the whole in the second direction Y is disposed with a scanning line 121. According to a direction indicated by an arrow in the second direction Y in FIGS. 1 to 5, the two scanning lines 121 and the one scanning line 121 are alternately arranged between the two adjacent light-emitting units 122 in turn.

That is, the two scanning lines 121 are arranged between the light-emitting unit 122 in a first row and the light-emitting unit 122 in a second row, and the one scanning line 121 is arranged between the light-emitting unit 122 in the second row and the light-emitting unit 122 in a third row; the two scanning lines 121 are arranged between the light-emitting unit 122 in the third row and the light-emitting unit 122 in a fourth row, and so on. In addition, a scanning line 121 is arranged on a side of the first row of the light-emitting units 122 away from the second row of the light-emitting units 122, or a scanning line 121 is arranged on a side of a last row of the light-emitting units 122 away from a penultimate row of the light-emitting units 122. This structural design makes the plurality of scanning lines 121 on the substrate 110 distribute regularly as a whole, which is helpful to an overall structural design of the display panel 100 and improve production efficiency.

Alternatively, as shown in FIG. 7, in the embodiments of the present application, two light-emitting units 122 of at least part of the light-emitting components 120 are respectively arranged between the two scanning lines 121 of the corresponding light-emitting component 120. That is, for the light-emitting component 120, the scanning lines 121 and the light-emitting units 122 are arranged alternately, so that the two light-emitting units 122 are respectively sandwiched between the two scanning lines 121. This structural design can reduce the scanning lines 121 arranged between the two light-emitting units 122 of a single light-emitting component 120, so that each sub light-emitting pixel 1221a can be electrically connected with its adjacent scanning line 121 directly, so as to reduce a risk of mutual crosstalk between the sub light-emitting pixels 1221a.

In some embodiments, one scanning line 121 and two scanning lines 121 are alternately arranged between two adjacent light-emitting units 122 in turn in the second direction Y. That is, if the plurality of light-emitting components 120 are regarded as a whole, a scanning line 121 is arranged on opposite edges of the whole in the second direction Y, respectively. According to a direction indicated by an arrow in the second direction Y in FIG. 7, the one scanning line 121 and the two scanning lines 121 are alternately arranged between the two adjacent light-emitting units 122 in turn.

That is, the one scanning line 121 is arranged between the light-emitting unit 122 in the first row and the light-emitting unit 122 in the second row, and the two scanning lines 121 are arranged between the light-emitting unit 122 in the second row and the light-emitting unit 122 in the third row; the one scanning line 121 is arranged between the light-emitting unit 122 in the third row and the light-emitting unit 122 in the fourth row, and so on. In addition, a scanning line 121 is arranged on the side of the first row of the light-emitting units 122 away from the second row of the light-emitting units 122 and the side of the last row of light-emitting units 122 away from the penultimate row of light-emitting units 122, respectively.

This structural design enables the sub light-emitting pixels 1221a in each light-emitting unit 122 to be electrically connected with the adjacent scanning line 121 directly without connecting cross pixels or cross scanning lines 121, so as to further reduce the risk of mutual crosstalk between the sub light-emitting pixels 1221a.

Alternatively, in the embodiments of the present application, the distribution modes of the three scanning lines 121 in the plurality of light-emitting components 120 are same. That is, the connection modes between the sub light-emitting pixels 1221a of each light-emitting component 120 and the corresponding scanning lines 121 are same. Hence, an overall connection mode of the plurality of light-emitting components 120 is in regular distribution, which is helpful to simplify a design of the pixel structure in the display panel 100, reduce production difficulty, and improve the production efficiency.

In some embodiments, the distribution modes of the three scanning lines 121 in the plurality of light-emitting components 120 can also be different, or a form of alternating design of multiple distribution modes in the above embodiments can be adopted, and its specific structure can be adjusted accordingly according to actual production requirements. There is no special restriction here, but only to ensure an effective regulation of the light-emitting mode of the plurality of sub light-emitting pixels 1221a in the display panel 100.

It should be noted that in the embodiments of the present application, the three scanning lines 121 of the light-emitting component 120 can all be located between the two light-emitting units 122 of the light-emitting component 120. Part of the sub light-emitting pixels 1221a in the two light-emitting units 122 are electrically connected with the adjacent scanning lines 121 directly, and part of the sub light-emitting pixels 1221a are electrically connected with a middle one of the three scanning lines 121. This structural design makes the distribution of the scanning lines 121 on the substrate 110 relatively concentrated and relatively less affected by the distribution mode of the sub light-emitting pixels 1221a, which is conducive to improving flexibility of the connection mode between the sub light-emitting pixels 1221a and the scanning lines 121.

Alternatively, in the embodiments of the present application, the light-emitting pixel 1221 comprises three sub light-emitting pixels 1221a, at least part of the light-emitting pixels 1221 is electrically connected with two data lines 130, and the sub light-emitting pixels 1221a in the light-emitting pixels 1221 are electrically connected with one of the data lines 130, respectively. As shown in FIGS. 1 to 7, taking multiple rows of three-row sub light-emitting pixels 1221a as a unit, the three row sub light-emitting pixels 1221a can be electrically connected with only two data lines 130. Compared with a tradition that three rows of the sub light-emitting pixels 1221a need to be connected with three data lines 130, it can reduce a distribution amount of the data lines 130, thereby reducing the production cost of the display panel 100.

In some embodiments, any one light-emitting pixels 1221 is electrically connected with two data lines 130. According to a direction indicated by an arrow in the first direction X in FIG. 1, every three columns are divided into a group, and each group is disposed with two data lines 130. Compared with a traditional distribution mode of the data lines 130, one data line 130 can be reduced in each group, so as to further reduce the distribution amount of the data lines 130 and reduce the production cost of display panel 100.

It should be noted that according to the different distribution modes of the scanning lines 121, part of the light-emitting pixels 1221 can be electrically connected with the two data lines 130, and part of the light-emitting pixels 1221 still retains a traditional setting mode of electrically connecting with the three data lines 130. This setting mode can increase selectivity of the connection mode between the sub light-emitting pixels 1221a and the scanning lines 121 and the data lines 130, and reduce the risk of mutual crosstalk between the sub light-emitting pixels 1221a due to line designs.

Alternatively, when one light-emitting pixel 1221 is electrically connected with two data lines 130, the data lines 130 can be arranged between two adjacent sub light-emitting pixels 1221a in the light-emitting pixel 1221, so that each sub light-emitting pixel 1221a can be electrically connected with the adjacent data line 130, so as to prevent cross pixel connection and reduce the risk of mutual crosstalk between the sub light-emitting pixels 1221a.

When each light-emitting pixel 1221 is electrically connected to only two data lines 130, and the data lines 130 are arranged between two adjacent sub light-emitting pixels 1221a in the light-emitting pixel 1221, in the first direction X, it is equivalent to that no data line 130 is arranged between the two adjacent light-emitting pixels 1221. Hence, connections between each column of the light-emitting pixels 1221 and the data lines 130 are independent of each other, which is helpful to simplify an overall layout design of the connection modes between the sub light-emitting pixels 1221a and the data lines 130.

Among them, each light-emitting pixel 1221 comprises three sub light-emitting pixels 1221a, which are red pixels, green pixels, and blue pixels respectively. In the embodiments of the present application, in the first direction X, the light-emitting pixel 1221 comprises red pixels, green pixels, and blue pixels arranged in sequence. In the second direction Y, the sub light-emitting pixels 1221a in a same column are pixels of a same color, so that when the sub light-emitting pixels 1221a are produced by a printing process, the printing can be carried out column by column, so as to improve printing efficiency.

It should be noted that in the first direction X, a color order of the three sub light-emitting pixels 1221a in the light-emitting pixel 1221 can be adjusted accordingly according to the design requirements, as long as colors of the sub light-emitting pixels 1221a located in a same column along the second direction Y are same, and there is no special restriction here.

It can be understood that the connection modes of the plurality of sub light-emitting pixels 1221a in each light-emitting component 120 with the scanning lines 121 and the data lines 130 are diverse, and specific connection modes can be adjusted accordingly according to an actual design situation. Changes made only to the connection modes are within the protection scope of the embodiments of the present application. Several of these connection modes will be described in detail below.

As shown in FIG. 1, in a light-emitting component 120, a first scanning line 121 is arranged on one side of the first row of the light-emitting pixels 1221, and a second scanning line 121 and a third scanning line 121 are arranged between two rows of the light-emitting pixels 1221. Each light-emitting pixel 1221 comprises three sub light-emitting pixels 1221a, the data lines 130 are successively arranged between the two adjacent sub light-emitting pixels 1221a in the light-emitting pixels 1221, and the data lines 130 are not arranged between the two adjacent light-emitting pixels 1221. Three rows of the scanning lines 121 and two columns of the data lines 130 can be electrically connected with six sub light-emitting pixels 1221a in one light-emitting component 120.

Wherein, any two sub light-emitting pixels 1221a of each light-emitting pixel 1221 in the first row are electrically connected with the first scanning line 121. Any two sub light-emitting pixels 1221a of each light-emitting pixel 1221 in the second row are electrically connected with the third scanning line 121. Remaining sub light-emitting pixels 1221a in the first row and the second row are electrically connected with the second scanning line 121. Meanwhile, the sub light-emitting pixels 1221a in the first column are electrically connected with the first data line 130. The sub light-emitting pixels 1221a in the third column are electrically connected with the second data line 130. And half of the sub light-emitting pixels 1221a of the second column are electrically connected with the first data line 130 and another half of the sub light-emitting pixels 1221a of the second column are electrically connected with the second data line 130. This setting method can not only ensure full utilization of the scanning lines 121 and the data lines 130, but also prevent the mutual crosstalk between the sub light-emitting pixels 1221a.

As shown in FIG. 7, in one light-emitting component 120, the first scanning line 121 is arranged on one side of the first row of the light-emitting pixels 1221. The second scanning line 121 is arranged between two rows of the light-emitting pixels 1221. The third scanning line 121 is arranged on another side of the second row of the light-emitting pixels 1221. The data line 130 is successively arranged between the two adjacent sub-light-emitting pixels 1221a in the light-emitting pixels 1221, and the data line 130 is not arranged between the two adjacent light-emitting pixels 1221.

Wherein, connection rules between each sub light-emitting pixel 1221a and the scanning line 121 and the data line 130 are consistent with connection rules in FIG. 1 above, which will not be repeated here. This setting mode enables the sub light-emitting pixels 1221a of each row to be electrically connected with the adjacent scanning lines 121 directly without connecting across the scanning lines 121, which can further reduce the risk of mutual crosstalk between the sub light-emitting pixels 1221a.

Alternatively, the substrate 110 is further disposed with a plurality of control switches 150. A number of the plurality of control switches 150 is equal to a number of the plurality of sub light-emitting pixels 1221a. The sub light-emitting pixels 1221a are connected with the control switches 150 in a one-to-one correspondence, and each of the control switches 150 is electrically connected with the scanning line 121 and the data line 130, so as to realize electrical connections of the sub light-emitting pixels 1221a with the scanning lines 121 and the data lines 130.

The control switch 150 is used to electrically connect the sub light-emitting pixel 1221a with the scanning line 121 and the data line 130, so that on and off of the corresponding control switch 150 can be controlled by changing input signals on the scanning line 121 and the data line 130, so as to control light emission of the corresponding sub light-emitting pixel 1221a. In addition, through a design of connection modes between the control switch 150 and the scanning line 121 and the data line 130, the light emission of the sub light-emitting pixel 1221a can also be controlled.

Alternatively, the plurality of scanning lines 121 and the plurality of data lines 130 on the substrate 110 form a plurality of cross areas 140. Each cross area 140 can be used as a connection point between the sub light-emitting pixel 1221a and the scanning line 121 and the data line 130. An arranging position of the control switch 150 can be adjusted according to a position of the cross area 140 to facilitate the electrical connection between the sub light-emitting pixel 1221a and the scanning line 121 and the data line 130.

A number of the plurality of cross areas 140 is equal to the number of the plurality of control switches 150, and the control switches 150 are arranged in each cross area 140, so that the plurality of sub light-emitting pixels 1221a correspond to the plurality of cross areas 140 in the one-to-one correspondence, that is, the product of the number of the plurality of scanning lines 121 and the number of the plurality of data lines 130 is equal to the number of the plurality of sub light-emitting pixels 1221a, so that a utilization rate of the scanning lines 121 and the data lines 130 reaches a maximum.

It should be noted that a position of the control switch 150 in the cross area 140 can be adjusted according to a position of the corresponding sub light-emitting pixel 1221a connected thereto, so that the control switch 150 is located at a position close to the corresponding sub light-emitting pixel 1221a connected thereto in the cross area 140, so as to shorten wiring between the sub light-emitting pixel 1221a and the corresponding control switch 150, reduce the risk of crosstalk between the sub light-emitting pixels 1221a, and reduce the production cost.

Alternatively, in the embodiments of the present application, each of the control switch 150 comprises a gate electrode, a source electrode, and a drain electrode. The gate electrode is used for electrical connection with one of the scanning lines 130, the source electrode is used for electrical connection with one of the data lines 121, and the drain electrode is used for electrical connection with one of the sub light-emitting pixels 1221a. Through a regulation of a scanning signal on the scanning line 130 and a data signal on the data line 121, conduction or disconnection between the source electrode and the drain electrode can be controlled, so as to control whether the sub light-emitting pixel 1221a emits light or not, so as to realize a regulation of the overall light-emitting effect of the display panel 100.

In some embodiments, the drain electrode of the control switch 150 is used for electrical connection with one of the data line 121, and the source electrode is used for electrical connection with one of the sub light-emitting pixel 1221a. The specific connection mode is related to a type and a line design mode of the control switch 150, which can be adjusted accordingly according to the specific situation, and there are no special restrictions here.

The gate electrode of the control switch 150 can be arranged on a same layer as the scanning lines 121 to reduce a number of film layers of the display panel 100 and reduce an overall thickness of the display panel 100. At a same time, a routing number between the gate electrode and the corresponding scanning line 121 can also be reduced and the production cost can be reduced.

In some embodiments, the gate electrode of the control switch 150 and the scanning line 121 are located in different film layers, the gate electrode and the scanning line 121 are separated by an insulating layer, and then an a via is provided at a corresponding position on the insulating layer to realize an electrical connection between the gate electrode and the corresponding scanning line 121. This structural design can reduce the risk of mutual crosstalk between the control switches 150 and ensure the display effect of the display panel 100.

Similarly, the source electrode and the drain electrode of the control switch 150 can also be arranged on a same film layer or on different film layers with the data lines 130. The specific setting mode can be adjusted according to an actual design situation, and there is no special restriction here.
